Sustained Primate Conservation

W. R. Kingston

There has recently been considerable publicity for the "Debt for Conservation" schemes, under which heavily discounted foreign debt notes are bought up by sponsors in the United States, converted back to local currency, and the much enhanced proceeds donated to government agencies promising to use them for "the purchase and maintenance of reserves including the provisions of guard posts and guards." This is undoubtedly a very good idea, and the very generous response of many U.S. citizens both to this and to World Wildlife Fund appeals shames the U.K. and western Europe generally. However, having spent the major part of the past twelve years working on conservation-oriented primate projects in Peru and Brazil, I am convinced that care needs to be taken to utilize this money to the best advantage rather than seeing it frittered away with no lasting benefits, at least to nonhuman primates.

There is no doubt that conservation of the whole habitat rather than one particular species should be the objective. The vast majority of species of platyrrhine primates occur in at least one of the reserves listed in the IUCN Directory of Neotropical Protected Areas, and most of these are government owned. There should therefore be very little need to purchase land for the protection of any species, the one obvious exception being the case of Brachyteles in Brazil, the main population of which is on a privately owned estancia.

With regard to guards or wardens, the current procedure of paying some local man a pitifully low salary and providing neither suitable equipment, transport, nor back-up facilities is worse than useless. To be anything like effective, there must be clear delineation of the duties and area under his charge; he must be paid a wage well above the local average to make it obviously to his advantage to keep his job; guards should patrol in pairs who should not be related. There must be a proper H.Q. building manned by a supervisor with wireless communication to the individual guards, who should be required to check in from suitably spaced posts on their territories at frequent intervals. Suitable transport``4 wheel drive vehicles or powered river boats``must be provided and liaison with the nearest police or military post kept open at all times. All this may sound very expensive, but even a very good local salary is cheap by U.S. standards: $100 (U.S.) per month is much above the current levels. The transport and other equipment would cost a lot less than the purchase of thousands of hectares of land. The funding authority should have the right to visit any site unannounced at any time, and to receive properly kept accounts of expenditure.

In practice, I do not think the concept of guards will ever be effective in most reserves in Amazonia unless the cooperation and involvement of local populations as a whole can be achieved. This will only come about if it can be demonstrated to these relatively uneducated but very practical people that conservation of the area gives them easily appreciated greater material benefit than its destructive exploitation. They cannot be expected to appreciate the concern for some small inedible and unsaleable creature, however important it may be to some remote "gringo," or to realise that the very tasty Ateles or Lagothrix they have hunted all their lives cannot reproduce fast enough to keep pace with improved hunting results brought about by the increasing availability of cheap shotguns. Their cooperation will be achieved if the reserve can provide regular work, either directly or by the provision of raw materials, such that the whole community benefits. Given this, they will support the guards and oppose destructive practices by anyone, including their own government.

The other essential requirement for continuity is the generation, or at least provision, of a regular income which must not be dependent on continuous appeals to the public of the developed nations. As I have said in an earlier paper (Kingston, 1985), machinery and equipment wears out and staff must be paid every month. There is a limit to public response, particularly when human tragedies of famine, flooding, and earthquakes result in an almost continuous appeal for funds, and we are quite obviously failing to control the suicidal population increases which are the greatest threat of all. Surely selected relatively small areas of the richest ecosystem in the world can be so managed so as to earn their own keep in a nondestructive manner. I am quite certain that this can be achieved in certain existing reserves in both Brazil and Peru, and at a cost well within the figures being published as available. A more detailed account of my proposals will be published elsewhere.

Preliminary Report on the Use of a Natural Foraging Task to Reduce Aggression and Stereotypies in Socially Housed Pigtail Macaques

Maria L. Boccia
University of Colorado Health Sciences Center


Nearly all nonhuman primates are highly social. Among the most significant elements that can be introduced for enrichment, therefore, are social companions (O'Neill, 1988; Reinhardt, Eisele, & Houser, 1988). Provision of social companions, however, may introduce several potential hazards. In addition to the problem of disease transmission, the prevalence of dominance hierarchies introduces the potential for competition for food, water, and preferred perch sites, as well as aggression leading to injury. The study reported here examines the impact of providing a natural foraging task on the agonistic behavior of socially housed pigtail monkeys.


A group of socially housed pigtail monkeys (Macaca nemestrina) , consisting of an adult male, 7 adult females, and 7 juveniles and infants, was studied. Water was freely available and food was provided at 0900 hr by scattering monkey biscuits and fresh fruit across the floor of the pen. The pen was 2.1x2.5x4 m. with cinderblock walls, wire mesh ceiling, and woodchip bedding on the cement floor. Additional space was provided with shelving and pipes.

Foraging consisted of a supplementary feeding of approximately one cup of sunflower seeds in the middle of the afternoons, 4-6 hours after the group was fed their daily ration of chow and fruit. The seeds were dispersed throughout the cage in the woodchip bedding. Animals were thus permitted to forage, by searching through the bedding, to find the seeds. For 2 weeks before and after beginning this regimen, five-minute focal animal samples of behavior were obtained from 5 females 9-10 years old, 3 females 4-5 years old, and 3 juveniles 1-2 years old. These data, including social and exploratory behaviors, were subjected to ANOVAs with condition (pre/post introduction of seeds) and age as factors.


With the introduction of the foraging task, social, exploratory, and abnormal behaviors changed. Stereotypies decreased (p = .04), and hairpulling, which prior to the introduction of the seeds occurred primarily in the afternoons, was nearly eliminated. In addition, bedding (p = .003) and other types of exploration (p = .05) increased, agonistic behaviors decreased (fight: p = .01; aggress: p = .08; submit: p = .01), and play increased (p = .01) (see Figure 1).

Figure 1: Behavioral responses of all monkeys observed in response to the introduction of sunflower seeds (Loc = locomote; AS = attempt to search outside pen; OE = explore objects; BE = explore bedding; SM = stereotypic motor behavior).

Several behaviors were differentially affected, depending on the age class of the monkeys: juveniles showed the greatest increase in play (p = .01) and decrease in locomotion (p = .008); adults the greatest increase in bedding exploration (p = .04). Affiliative behaviors showed different changes depending on the monkey's age: juveniles showed a decrease, while the adults and subadults showed an increase (p = .04) (see Figure 2).

Figure 2: Different responses of adults, subadults, and juveniles to introduction of sunflower seeds.


Feeding strategies may compound or reduce the hazards of housing primates in social groups. Given the trend toward social housing as an enrichment strategy for laboratory primates, it is imperative to discover techniques which can be easily and inexpensively implemented ,cb and which will minimize aggressive behavior and the attendant risk of physical injury. The presence of a food which requires a natural foraging activity not only reduced such agonistic behavior and increased play, but also reduced stereotypies, including hairpulling behavior in the pigtail macaques studied here. The effects of this manipulation were somewhat affected by the age of the monkeys, suggesting that the impact of enrichment strategies will have to be assessed for differences across age and possibly sex, as well as for species differences.

It appears to be possible, however, to use social housing as a means of enrichment for primates, and incorporate management procedures that will reduce the levels of stereotypies, and the potential hazards of agonistic interactions. A follow-up study is currently in progress to determine if this foraging task continues to be effective in reducing aggression, hairpulling, and stereotypies on a longterm basis.

Nylon Balls Re-visited

Kathryn A. L. Bayne
National Institutes of Health

Renquist and Judge (1985) have recommended placement of nylon balls&S'1. in the cages of singly-housed nonhuman primates for the purpose of environmental enrichment and prevention or reduction of abberant behaviors. The absence of any specific description by Renquist and Judge of the ways in which nonhuman primates use nylon balls prompted this author to further investigate the kinds of interactions the animals have with this device. In a comment appended to Renquist and Judge's article, the editor of this journal indicated that from a management standpoint the potential for noise disturbance might be a negative outcome of the incorporation of this enrichment device in nonhuman primate cages. Renquist and Judge also noted one instance of a ball that blocked a floor drain, and the destruction of a $7000 sewer pump has been reported to this author. These illustrations aptly point out that no enrichment device is without its drawbacks, some of which can have unexpected economic impacts.

Informal observations of the nonhuman primates in two animal rooms were made for 30 to 90 minutes between 1000 and 1600 hrs, two to three times a week over a period of three months. The animals in the rooms had been maintained in the facility from less than one year (for infant and juvenile monkeys) to five years. They ranged in age from less than one year to 27 years. As the animals came from a variety of sources (both feral and captive born), they represented a broad scope of rearing conditions (nursery, nuclear family, peer, mother/infant, mother/peer). Each cage in this particular facility at the NIH is routinely equipped with a nylon ball; therefore all animals had been exposed to the ball from the time they were placed in their cages. It may be assumed, then, that any consistent interaction between an animal and the ball was not due to a novelty effect.

*  Animal sits on ball, occasionally with legs propped up 
   on cage wall
*  Animal holds ball with hands or feet
*  Animal chews on/bites ball
*  Animal holds ball in mouth while sitting or moving around 
   the cage
*  Animal picks at seam of ball
*  Animal paces around cage and moves ball with hand with each 
   pass by it
*  While sitting, animal repeatedly rolls ball away and watches 
   it roll back
*  Animal rubs ball on cage floor, thereby generating noise
*  Animal repeatedly picks up and drops ball

Table 1: Observed interactions between nonhuman primates and nylon balls.

During each half-hour period a minimum of three animals out of an average of 34 animals in a room (different animals during different observation times) manipulated the nylon ball. This figure of 10% of the rhesus population coincides with what Line (1987) has reported. During a single half-hour observation period seven animals (19% of the animals in the room) interacted with a ball. The various ways in which the rhesus (Macaca mulatta) , stumptail (M. arctoides) , and cynomolgus monkeys (M. fascicularis) used the nylon ball are described in Table 1. As can be expected with any enrichment tool, some individual animals routinely manipulated the nylon balls while others interacted with it less frequently or not at all. Occasionally the interaction was part of a stereotypic pattern (e.g., circling around the cage and touching the ball with each pass), so it may be suggested that for those particular animals the presence of the nylon ball has not eliminated all the abnormal behavior patterns manifested by these animals. Also, one animal consistently incorporated the nylon ball into a self-abusive behavior pattern, alternately biting his leg and the nylon ball.

An environmental enrichment device like the nylon ball helps elucidate features of devices in general which are important to the animal. Since the design of the nylon ball is very simple, it may be easier to identify those features of it which are the most salient and interesting (or "species appropriate," as Line refers to it) to the animals. These features may then prove to be important in directing the design of future enrichment devices aimed at improving the psychological well-being of nonhuman primates.

The concept of improving psychological well-being by providing an animal with control over its environment is often referred to by investigators in this field (Novak & Drewsen, 1988; Line, 1987; Mineka et al, 1986; Curtis, 1985). Does the nylon ball confer to the nonhuman primate some control over the cage environment (e.g., by using it to generate noise)? If it is regarded by the animal as an extension of the cage, then it is one of the few elements that is moveable. This mobility or portability may be an attractive feature of the ball. Baldwin and Suomi (1974) have found that infant rhesus monkeys explored moveable objects more frequently and for longer durations than stationary stimuli. For example, many animals, when given the opportunity to do so, will operate the squeeze apparatus of their cages by themselves on a regular basis. This, too, may be a demonstration of the animals' need to be able to alter the environment themselves, or live in an environment which is changeable to some degree. Often the first reaction of a nonhuman primate to its new cage is to pick up the nylon ball and cling to it while moving around the cage (M. April, personal communication).

Even if the nylon ball is not regarded by the animals as an extension of the home cage per se, it is certainly viewed by some animals as "property" or part of the home territory. Animal care and laboratory technicians have reported to this author how difficult it can be to remove a nylon ball from an animal's cage, as the animal will often grab the ball and hold it away from the individual attempting to remove it. Do enrichment strategies that require the rotation of devices or "toys," then, inject an element of stress into a program designed to improve "psychological well-being" by periodically removing part of an animal's territory and substituting a novel object?

Since approximately 10% of the monkeys in a room utilize the ball at any given time, the consistency in appeal of the nylon ball is not equal for all macaque species or individuals. Yet, many animals interact with the ball on a regular basis. As can be expected with any enrichment device, then, the nylon ball is not a ubiquitous solution for enhancing the psychological well-being of nonhuman primates. For researchers, the nylon ball may be useful as a tool to assist in the identification of those features of a device which are interesting to nonhuman primates and which could be incorporated in novel enrichment devices and strategies.

Polyvinyl Chloride Piping as Perch Material for Squirrel Monkeys

Axel V. Wolff
National Institutes of Health

Environmental enrichment and methods to encourage and facilitate primates to exhibit species-specific behavior are issues receiving increasing attention (Reinhardt & Smith, 1988; Reinhardt et al, 1987; Line, 1987). Polyvinyl chloride (PVC) piping has been successfully used for primate cage enrichment by various institutions. The present article illustrates how our facility utilizes this material as perches for squirrel monkeys (Saimiri sciureus).

A colony of 250 squirrel monkeys of both sexes and of varying ages was studied. They are at the Laboratory of Central Nervous System Studies, National Institute of Neurological and Communicative Disorders and Stroke, animal facility in Frederick, MD. The animals were housed one to four in each standard stainless steel (Harford Metal Products, Inc.) primate cage measuring 20x22x34 in.

To enrich the cage environment, PVC piping was installed. The 1/2-inch internal diameter piping, cut to lengths of 20-1/4 inches, was capped at both ends. The caps allowed the piping to be wedged securely into the cage, but facilitated rapid removal without the use of tools. The caps also effectively sealed the interior of the pipes. The small size of the squirrel monkeys prevented them from moving or dislodging the perch in any way. The perch became a part of the cage and could be easily cleaned in place. However, since disinfection in 180deg F water in an automatic cage washer tends to distort the shape of the perch, removal of the bar and soaking in a mild sodium hypochlorite solution was preferable.

Initial reaction to the perch on the first few days was one of apprehension, followed by curiosity, and finally acceptance and usage. Within one month of introduction, usage of the perches was exhibited by all animals at some time during the daily routine. Perch usage consists of sitting, eating, sleeping, and locomotion in a fashion similar to tree limb use in wild monkeys. Occupation of the perch can be by one or all cagemates. Aggression for possession or control of the perch has not been noted.

Sanitary perches for small arboreal primates, such as squirrel monkeys or marmosets, encourage species-specific behavior without compromising routine husbandry or sanitation procedures. Cost, installation, and maintenance are minimal. Larger species need more permanently anchored perches. An additional unexpected benefit of the PVC piping has been a decrease in dorsal tail-head abrasions, frequently seen in squirrel monkeys that sit on the stainless steel flooring of standard primate cages.

Rhesus Monkey Colony Management: A 1988 Update


This workshop is a follow-up to a symposium on colony management of rhesus monkeys that I organized for the 1986 ASP meetings in Austin, TX. We had representatives from five of the NIH supported Primate Centers (Oregon, Washington, California, Yerkes, Delta), Yemassee, and the Caribbean Primate Research Center. At that time, it was strongly suggested that we continue the exchange of information, hence, the present workshop. This year we see the addition of the New England Primate Center, as well as representatives from two commercial breeders of macaques.--Margaret R. Clarke.

Charles Rivers Key Lois

I'll give you a brief overview of the Charles Rivers Colony in the Florida Keys. Key Lois was started in 1973 as a commercial venture, and in 1976 we started a colony with the FDA on Raccoon Key. Our base of operations is Summerland Key, about 25 miles north of Key West. Key Lois is about 100 acres, about 3 km out on the Atlantic side, and has about 1500 rhesus. Raccoon Key is about 200 acres, about 5 km out on the Gulf side, and has about 2200 rhesus.

The main problem we're having right now is defoliation. The islands have become overpopulated, especially Key Lois, which has really been stripped. We are reaching agreements with the Departments of Environmental Regulations and of Natural Resources of the state of Florida, whereby we will reduce the free-ranging population by putting a few corrals on the island. I hate to get into that, but there is no alternative if we are to meet our commercial obligations. So we will, in the future, have a combined corral/island operation.

The other problem with our colony is that we should have had more planning for replacement breeders. A lot of our native Indian animals are reaching 17-18 years of age and the birth rate is starting to drop. We are going to have to concentrate on replacing breeder stock. Along with the corral operation, we're not sure exactly what that is going to do to us, but I'm not taking any new orders right now.--Paul Schilling, Charles Rivers Key Lois, Box 259, Summerland Key, FL 33042.

Yerkes Regional Primate Research Center

As we reported at the Austin meetings in 1986, a series of overthrows of the highest ranking matriline in one of our rhesus groups took place between January of 1976 and February of 1983. Three of these 4 overthrows occurred between late 1982 and early 1983. These were the result of predominantly adult female members of the multiple lower ranking matrilines jointly attacking the adult female and adolescent members of the then-highest-ranking matriline of the group. In the 3 overthrows of 1982 and 1983, the next-ranking matriline assumed highest position, while the surviving members of the deposed matrilines fell to, or near, the bottom of the hierarchy. The group has been under continuous study since the last overthrow in 1983 and, in sharp contrast to the instability of late 1982 and early 1983, we can report that there have been no similar matrilineal overthrows, nor any significant changes in the matrilineal rankings since that time. Female dominance relationships have remained quite stable for the last 5 years, aside from expected maturational changes, and these also have been largely predictable in terms of youngest sister ascendancy.

We also reported in 1986 that the lack of participation in the overthrows by adult males, and their ineffective defense of the members of the attacked alpha matriline demonstrated independent functioning of the female core of the group from these adult males. Further evidence of this was noted in the fall of 1985, when all of the adult male members of the group were removed as part of an on-going research project. Their removal did not lead to any reorganization of female dominance relationships and the relative rankings of the matrilines have remained stable.

The relative positions at the bottom of the matrilineal hierarchy of the members of the overthrown matrilines which have remained in the group have also remained fairly stable, with one notable exception. A female of the alpha matriline overthrown in late 1982 (who was orphaned at that time when she was less than a year old) is now fully mature and has risen in rank to a position within that of the alpha matriline. This was a consequence of a relationship that she formed with an adult female member of the alpha matriline and despite resistance on the part of several mid-ranking adult females. After obtaining her high rank, she then aided her older sister, who began challenging higher ranking females, and she, too, rose drastically in rank. There is nothing to suggest, however, that other female members of the deposed matrilines will attain positions held by their mothers at the time of the overthrows. This is true for females who were adults when their matrilines were overthrown, as well as for those who were infants or very young juveniles at the time.

I think these observations recorded in the years since the series of overthrows support three basic conclusions regarding this group: First, this group is in no way characterized by what might be labeled "long term instability or abnormality." Second, young animals of overthrown matrilines can remain viable members of their group after the violent depositions of their matrilines, although they are likely to remain low ranking. Finally, not only were the violent reorganizatons which took place in the past independent of the adult males, but the stability which followed the overthrows has been maintained for over 5 years now, despite removal of all of the adult male group members in 1985.--Carolyn Ehardt, Department of Anthropology and Linguistics, University of Georgia, Athens, GA 30602.

I'd like to share a little anecdote with you. When we removed all of the adult males in 1985, the only males left in the group were immature natal males. Our alpha female's younger brother became the alpha male, but was, and still is, subordinate to his sister, although he was dominant to all of the males in the group. At age 4-1/2, he appeared to be the absolute alpha male in that group, and everything seemed to be perfectly in order until, one day, to our total surprise, a bunch of males in the group ganged up on him, attacked him, and beat him quite severely. We pulled him out immediately. He had minor injuries, but some of the cuts were deep. His matriline had come to his aid, and several of them were roughed up a bit, but his matriline retained status. When we returned him to the group he was immediately the target of attack by all of the other natal males. His matriline came to his aid at once. His sister sat directly in front of him and just stared at any male that tried to get to him, which turned out to be very effective. His aunt, a much larger and more vigorous female, physically attacked any male who came near him. Since she was about 7 kg and was attacking 8 to 9 kg males, she got roughed up, and then couldn't defend her nephew against other attacking males. So her vigorous attack was far less effective than the passive defense his sister provided.

We also noted something that had been reported previously. The female members in the matriline defended the males, while the alpha female's 2-year-old nephew and a very vigorous 4-year-old cousin led all the other males past their aunt and their mother to attack the alpha male. It appeared to us that other females were beginning to take advantage of that by moving in, and we feared that the alpha matriline might be overthrown in defense of this male. At this point, we elected to pull him out of the group. That was 1-1/2 years ago, and the alpha matriline has re-established itself; everything is as it was before. We felt that the male attack on this male did jeopardize the stability of the alpha matriline, and his removal re-established stability in the group. This demonstrates once again that female members are faithful to the matriline, whereas males are not. They are independent and fight quite freely with each other regardless of matrilineal affiliation. The matriline may give some support to a male, but the dominance position of a matriline does not seem dependent on the support or dominance of its male members.--Irwin Bernstein, Department of Psychology, University of Georgia, Athens, GA 30602.

New England Primate Research Center

The timed-mating program at the New England Regional Primate Research Center (NERPRC) includes 170 rhesus females and 25 males. We assign 60 of their offspring each year for fetal and developmental research, returning another 30 to 40 to our colony. This program is now producing its fourth generation.

NERPRC is reorganizing to allow more social contact among the program's females. Construction is nearly complete on a new building giving animals living in 15-18 m&S'2 rooms access to outdoors. Each room will house 3-5 females. Individuals move to a breeding room around the time of ovulation. We anticipate two main areas of difficulty with this program: a) the transition from the single cage environment to the small group setting; b) regular changes in the composition of the groups as individuals move to and from breeding rooms.

In 1987 we established a primate ethology unit to carry out ongoing studies of behavior of the monkeys to establish protocols for reintroductions and group formation for long term individually housed monkeys. This works as 4 components: 1) retrospective searches of the animal records to establish the extent and nature of their social experience; 2) applying one or more behavioral assessment scales; 3) observing their interactions in groups of 2 or 3; and 4) comparing the success of each individual with data collected in the other steps to develop a predictive model for successful resocialization.

We followed these steps in the establishment of a specific-pathogen-free colony in late 1987, consisting initially of about 25 rhesus monkeys with low or absent titres to type D retrovirus and Herpes B virus. This preliminary test of the protocol for social group formation from individually-housed animals was successful. To date, we've removed 1 female who was overly aggressive, 2 who never integrated into the group, and 1 whose B virus titre increased. Last year this colony produced 3 births, and we have added about 60 more juvenile rhesus and crab-eating monkeys in 3 other groups.

We are especially interested in the experiences of others who have made the transition from single to group-housed animals on a similar scale. We would also like to hear from colleagues using a variety of behavioral assessment methods to plan and monitor the progress of these moves.--Andrew J. Petto and Lyna M. Watson, NERPRC, One Pinehill Drive, Southborough, MA 01772.

Oregon Regional Primate Research Center

The first rhesus breeding corral at the Oregon Regional Primate Research Center was constructed in 1974. This 1-acre corral was initially stocked with 55 adult females and 13 adult males, which were a mix of wild-caught animals from India and colony-reared animals from the Center. In the following 3 years, 5 additional corrals were constructed. Maintenance of the corrals continued uneventfully until 1981, when a significant amount of fighting occurred among females. Genealogical analysis of animals involved in episodic aggression suggested matrilineal overthrows.

A number of different procedures were initiated in an attempt to reduce the fighting: 1) Grain was scattered to distract the animals. 2) Barrels were placed in the corrals to serve as hiding places. 3) The policy of treating and then returning injured monkeys was modified. If a monkey was removed for more than a week, it was not returned. 4) The number of adult males was increased in the corrals to control the fighting. 5) Animals were harvested from low-ranking matrilines, rather than equally from all matrilines.

Despite these changes in management practices, bouts of serious aggression continued. Two years ago a new management policy was instituted that involved eliminating matrilines. Two corrals were stocked with 2- and 3-year-old unrelated females. Current plans are to harvest all the yearling males, and all the 2-year old females every year from each corral. After a period of 6 to 8 years, corrals will be decomissioned in rotation, and the remaining adult females will be transferred to the Center's timed breeding colony or to research projects. New corrals will again be formed with a mix of 2- and 3-year-old females that have been harvested from other corrals.

This program appears to be working well. Birthrates in the two newly constituted corrals have been high, and there have been no significant episodes of serious aggression. However, two problems have occurred. 1) There is a relatively high rate of infant mortality among primiparous females. Differences in maternal behavior have been reported between multiparous and primiparous rhesus females and these will be investigated. 2) The corrals were stocked with age-graded cohorts of males (i.e., several 2-year-olds, several 3-year-olds, etc). When the young males reached puberty they were attacked by older males. Current plans are to put fully adult males in a corral. These males will be left as a group after the corral has been decomissioned, and then they will be released into a new corral. Separate groups of adult males will be rotated among the corrals to reduce inbreeding.

This program is supported by RR-0163 from NIH, USPHS.--G. Gray Eaton, Michael Axthelm, Stephen T. Kelley, & W. P. McNulty, Oregon Regional Primate Research Center, Beaverton, OR 97006.

Delta Regional Primate Research Center

This is an update on introductions of adult males into corral-living groups of rhesus monkeys at the Delta Primate Center. The FDA rhesus monkey breeding colony, consisting of 22 one-half acre corrals, had been stocked in 1974 with 5 males and 45 females each (sex ratio 1:9). By 1985, the sex ratio in some was as high as 1 male to 35 females. In the Fall of 1985, we formed 5 all-male groups, each with 5 to 9 fully adult males. They were housed in catchpens adjacent to corrals needing males, and were given a period of time to adjust to each other. Females from the adjacent corral were introduced, a few at a time, for 1-week periods, until they had all been with the males, and then the males were released into the corral. This approach failed for two reasons; the males became competitive in the presence of females and started fighting, and the females were attacked by group members once they were returned to the corral. Four of 5 females in one group were dead within a few hours of being returned to their corral, despite the fact that they never had been out of visual contact. In conjunction with these two problems, this procedure did not result in any improvement in the number of males being successfully introduced into established social groups.

In the Fall of 1986 and 1987, with advice from Irwin Bernstein, we implemented a new program which has been more successful. We target corrals with no or few males for replacement males. Those males are removed one full month before the start of the breeding season, and are housed in groups of 4-6 in catchpen areas. Peer groups of maturing males (4-5 years of age) are also housed in catchpen areas. Males are introduced approximately 1 month after the females start cycling. Males are released into a group with which they have had no social experience, which in our case also means that they are not released into the corral adjacent to their catchpen. The timing of the introduction is crucial as it must coincide with the breeding season for females who have not been with males. The only time free-ranging rhesus females accept males into the social group is during the breeding season, and this behavior is unchanged in corral-living situations. The males are released early in the day into their target corrals, and they are observed until dusk. If there are problems, the males are returned overnight to the adjacent catchpen and are released again in the morning.

In the Fall of 1987, we introduced 52 males. Twenty-two of them (42%) were accepted and now are living in the corrals. Twenty-one were pulled out because it was obvious that they were not integrating into the group, and these are being housed in peer groups until October, 1988. Nine animals were euthanized for trauma injury, but none were killed outright by group members.

The success of introduction correlated with the origin of the all-male group. We had old colony males, maturing Delta-born males, maturing Hazleton males who had always lived in social groups, and maturing Davis males who had been born in social groups but had been singly housed since 1 year of age. All of the younger males had been housed in catchpens at Delta for 4-6 months prior to introductions. The group of 3 old males entered their new group without incident, and they continued living there throughout the breeding season. Of the 14 Delta-born males, only 3 were successful at group membership, and remained in the corrals. Four were euthanized for trauma, and 5 are waiting for another chance this next year. Of the Hazleton/Davis animals, there was a 46% success rate. Four of the Davis males are in the group, 4 are waiting for this next year. Twelve of the Hazleton males are still in social groups, 10 are waiting for next year, and 5 were euthanized. Thus, the older males were the most acceptable, but the next most acceptable were complete strangers. There were no significant differences between the socially-housed Hazleton males and socially-then-singly-housed Davis males.

We will have more data next Fall. Many old males are dying of old age and must be replaced. We are particularly interested in looking at the success rate for animals rejected last year compared to first time introductions, in hope of identifying characteristics of males not having the social or physical expertise to successfully join an established group. We will continue to develop a plan for the proper combination of timing, group composition, and individual characteristics to maximize success of male introductions.--Margaret R. Clarke and James L. Blanchard, Delta Regional Primate Research Center of Tulane University, Covington, LA 70433.

Hazleton--Texas Primate Center

The Texas Primate Center is located approximately 40 miles west of Corpus Christi, TX. It is a 208 acre facility with 688 corncrib type cages, housing approximately 6000 macaques; 750 are cynomolgus, the rest are rhesus. Breeding harems are comprised of 1 male to an average of 7 females. The facility is divided up into colony areas, with a colony support building provided for each area.

The first procedure to be discussed is the return of convalescing adults back into the colony. Because of our limited hospital space, it is imperative that we return animals back to the harems as quickly as possible. We select animals, particularly adult females that have completed medical treatment but are still in need of some convalescence, for placement in corn cribs with 10-12 juvenile weanlings. One to 3 females will stay in that crib until fully recovered and strong enough to go back into breeding harems. This procedure normally works very well. The juveniles seem to enjoy having the adults in their presence, and the adults are certainly under less stress than they would be going directly into breeding harems with other adult animals. Once they have recovered, it is much easier to introduce them back into groups. Normally, individual females or small groups of females are placed together to make up totally new harems.

The second procedure to be described is our foster infant program. Approximately 30 infants a year are either rejected or orphaned at or near birth. We have no nursery, and we have a policy which prohibits taking those infants home and hand rearing them. An alternative is fostering as a means of saving these offspring. Our technique is to take the individual infant out to the colony and go from crib to crib to locate females that have a particular interest in the infant. We then select one of the females carrying an infant of a similar age, place them in an individual cage, and introduce the infant to be fostered to her. Normally the female will accept the infant. If everything seems to be going well, we leave all 3 animals inside for a 5 to 7 day period for observation before returning them to the harem. Occasionally it's necessary to repeat this procedure with another female if incompatibility develops. In some cases, if lactation doesn't appear to be adequate at first, we supplement the infant with infant formula 2 to 3 times a day until we are sure that it is feeding adequately.

The third procedure is introduction of breeder males into groups of established breeder females. At the time of quarterly TB testing, animals are palpated for pregnancy. Once we finish testing the colony, we evaluate conception rates in the various harems, and develop a plan to share the more productive males with those harems that have lower conception rates. We accomplish this sharing by swapping the groups of females, leaving the males in place. We find that we have much better acceptance of the males by using this technique. We also have found that it is more successful when we select groups of females from distant parts of the colony where they have not had visual and vocal contact with one another. Normally we can determine the compatibility very quickly. When it is not successful, we generally remove the most aggressive females from the group. Other times it is necessary to split up the group completely and establish new breeding harems.--Steve Pearson, Hazleton--Texas Primate Center, P.O. Box 549, Alice, TX 78332.

California Primate Research Center

The problem I want to address today is inbreeding, a problem for the management of all captive primate populations where natural male migration is not possible. Our population consists of approximately 1000 rhesus, housed in 1/2 acre field cages at the California Primate Research Center (CPRC). David Glenn Smith, using Paternity Exclusion Analysis at the CPRC, found that rhesus mate randomly with regard to paternal kinship, but only one case (full sibs) of matrilineal inbreeding was found. In an earlier study (1977-84), Smith compared the 40 inbred individuals he found in the CPRC field cages to non-inbred individuals. The only statistically significant difference was that inbred animals had slightly lower birth (but not growth) rates. However, he noted that reproductive loss is greater after 3-4 generations, so there may be a problem in the future at the CPRC. Inbreeding is a problem in biomedical research when a source population becomes genetically homogeneous and distinct from other primate center populations. (Are research results compatible if test animals come from genetically distinct populations?)

The CPRC has been working on two solutions to the problem of inbreeding. The first is to increase genetic diversity through the introduction of rhesus from diverse geographical populations. Most of the CPRC rhesus are of Indian origin. In 1982, 3 Chinese rhesus males were introduced into a cage of 53 juvenile Indian rhesus. These males have now produced a number of hybrids who weren't significantly different from non-hybrids when they were studied as infants by D. G. Smith et al, but which now appear larger than their Indian counterparts.

In October, 1987, we introduced 3 Burmese rhesus males into a field cage of 73 juveniles (1.5 to 3.5 years old). At that time, we were concerned about trauma due to general xenophobia, and the fact that some of the Chinese hybrid juvenile males were actually larger than the Burmese males. However, when the Burmese males were released into the field cage, all juveniles retreated to the ceiling and sides of the cage, where they stayed for several days. We had one breeding season (1987-88) with the Burmese males in the field cage, resulting in 13 conceptions and 11 live births to date. All the mothers are primiparous and are doing beautifully, but the Burmese males did not fare so well. In January 1988, the oldest of the males (approximately 16 years) was hospitalized for dehydration and hypothermia. In March, the alpha male (second oldest at approximately 12 years) was badly traumatized by unknown assailants and removed from the cage. Neither male was returned to the field cage. By late spring, the new alpha male was a 3-year-old Chinese hybrid, even though there were 6 older males in the cage with him. Upon completion of Dave Smith's paternity exclusion analysis we should know if the fathers of the 1988 infants in this field cage are Burmese and/or the younger Chinese and Indian males.

The second solution is an infant cross fostering program launched by Steve Smith in 1984, and first reported at the ASP meetings in Austin in 1986. This program started as a series of infant swaps between field cages, and Steve Smith was able to make 36 swaps in 3 years with a 75% success rate. Thirty-two of the 36 fostered animals are still in the field cages, including one 5-year-old female (who unfortunately had a stillbirth this year), and eight 4-year-old males. We don't know yet what their reproductive success (RS) will be.

This year to date we have been successful in 11 of 14 infant foster attempts (79%). The three failures were an infant reject, a mutual reject, and a maternal reject. Examining both infant and maternal behavior, it looks as though we need to pay more attention to temperament differences in order to increase fostering success rates. Infants who are highly agitated during the transfer process may not be very good candidates for fostering; the best foster pairs are very calm mothers with very calm infants. Six of the 11 fosters this year were genetic fosters--that is, we took either full Chinese, 1/2 Chinese, or 1/2 Burmese rhesus infants born indoors and swapped them with infants in the field cages. These fosters were all successful. We did just one straight foster of an animal that was born in the field cages. He was rejected by his mother (who had been quite ill), raised in the nursery for nearly a month, and then fostered to a primiparous female who had a stillbirth. Both mother and infant are doing well.

It has also become apparent from D. G. Smith and S. Smith's work at the CPRC that both males and females inherit maternal rank but 1) RS of natal males is significantly correlated with maternal rank and not paternal rank (although the son of a high-ranking female and an alpha male has an additional RS bonus) and 2) the advantage of maternal rank does not seem to accrue to daughters. Given greater variance in male RS, we are now attempting to place male foster infants only on high-ranking (especially alpha) females, and placing female foster infants only when male infants are not available.

There are several things we don't know about inbreeding but are working to understand. One is the actual lifetime RS of fostered individuals; we're banking on very successful male breeders in the future. We don't know enough about the long term effects of inbreeding as we haven't had enough inbred animals to know how serious a problem this will be. We also don't have enough information about hybrid vigor, although our subjective impression is that Chinese hybrid males seem consistently larger and higher ranking than their pure Indian counterparts. In the future we will continue the infant cross fostering program and attempt to diversify the CPRC rhesus population even further. We are expecting some Vietnamese animals from Sukhumi this fall and hope to use these animals to start a new field cage with juvenile rhesus of Indian stock--Linda M. Scott, California Primate Research Center, Davis, CA 95616.

Letters: Endangered Chimps

No Controversy

The opening paragraph in the article "Chimps and Research: Endangered?" (Laboratory Primate Newsletter, 1988, 27[4], 9-12) states that scientists in the conservation and biomedical communities are "at each others' throats," the latter "clamoring for chimps for AIDS research." On the next page there is a reference to "a letter to Nature " by Alfred Prince and Jane Goodall, opposing importation of chimpanzees from the wild for research and arguing that the current captive population is sufficient for research needs.

The letter mentioned is a position paper by Alfred M. Prince, Jan Moor-Jankowski, Jorg W. Eichberg, Huub Schellekens, Rudolph F. Mauler, Marc Girard, and Jane Goodall, which appeared in volume 333[6173], 1988, p. 513 of Nature. Not only Dr. Prince but five of the other co-authors are well-known for their biomedical research using chimpanzees, so our paper proves that there is no controversy between us and our co-author, Dr. Jane Goodall, the noted conservationist. Dr. Eichberg, the co-discoverer of the chimpanzee as a model for human AIDS, is responsible for a large chimpanzee colony in the U.S., as am I. Dr. Schellekens directs the hepatitis and AIDS program in the large Dutch chimpanzee center, supported by the European Economic Community as an international resource, while Dr. Girard directs the vaccine research at Pasteur Vaccins, France, and Dr. Mauler the vaccine program at Behringwerke, West Germany.--J. Moor-Jankowski, Director, Laboratory for Experimental Medicine and Surgery in Primates, New York University School of Medicine, 550 First Avenue, New York, NY 10016.

Restrictions on Use

Since the "endangered" classification places significantly greater restrictions on the use of such animals, including those already in captivity, many areas of disease prevention and treatment research, including studies on AIDS, could be severely hampered by this reclassification, particularly those for which chimpanzees may be the only appropriate research animals. Any reclassification should be based upon a responsible and objective survey of the number and circumstances of chimpanzees in the wild and not on anyone's guess or wish. It is important to note that no chimpanzees are being imported to the United States from their natural habitats in the wilds of Africa.

In 1973, the U.S. joined the Convention on International Trade in Endangered Species (CITES), and it became law in 1975. Since then, the U.S. has not imported chimpanzees from the wild. Thus, reclassifying the chimpanzees as "endangered" would not provide additional protection of these animals from exportation from Africa to the U.S., since our government already abides by CITES. And, contrary to current rumors, the National Institutes of Health does not plan importation of wild chimpanzees.

It should also be recognized that the NIH has established a National Chimpanzee Breeding Program in the U.S. to insure that chimpanzees do not become extinct in captivity and that there will remain an adequate supply for biomedical research in this country. This Program and the concern of the scientific and zoological community can assure the long-term survival of this species in captivity. Regardless of how chimpanzees are classified, it is essential for the advancement of several areas of medical studies that those chimpanzees presently in research institutions and their progeny of the future continue to be available for research so long as their numbers in research and breeding establishments in the U.S. are stable or increasing.--Frederick A. King, Director, Yerkes Regional Primate Research Center, Emory University, Atlanta, GA 30322.

Pet Chimpanzees

We know the number of chimpanzees in research institutions and government facilities, and even have a general idea of the number left in the wild, but how can we account for the number in this country owned by private individuals as pets? The Primate Supply Information Clearinghouse (PSIC) has received calls from owners of fairly young (2-3 years old) solitary chimps who want to locate and buy another. Many of these pet owners are upset at the problems locating a supply, and if they do find some breeder who has one for sale, they don't like the current price! Would changing the status from Threatened to Endangered essentially eliminate the private ownership of young chimpanzees? How many of these privately held animals will have to be "given" to a colony or sanctuary when they become adults? Who is monitoring the health status and census of these animals, and how did they become "obtainable" by anyone with the money? I doubt if there are answers to these questions, and I doubt if we can investigate very thoroughly, as I have had numerous dealings with commercial importers, distributors, and pet stores selling these and other "exotic" animals. Their records, histories, and dates of receipt become conveniently vague. There are also problems with which authorities to report these animals to, lack of manpower among the authorities, and lack of somewhere to send confiscated animals.--Cathy A. Johnson-Delaney, PSIC, University of Washington, Seattle, WA 98195.


The U.S. Fish and Wildlife Service has decided to reclassify wild chimpanzees as "endangered," while leaving chimps living in research facilities under the less dire heading of "threatened." The compromise will allow experimentation on man's closest relative to continue, while bringing into play more stringent restrictions on the importation of chimpanzees from Africa, where the species is under severe pressure due to massive habitat destruction, hunting, and capture.--From a News and Comment article in Science, December 2.

Guidelines to Prevent Simian Immunodeficiency Virus Infection in Laboratory Workers and Animal Handlers

Simian immunodeficiency virus (SIV) belongs to the family Retroviridae (subfamily Lentivirinae) and is closely related to human immunodeficiency virus types 1 and 2 (HIV-1 and HIV-2), the etiologic agents of acquired immunodeficiency syndrome (AIDS). Although no reports of infection in humans have been documented, the expanding use of SIV as a model of HIV infection has raised concern about the potential risk of SIV transmission to humans. Therefore, a working group was established by CDC and the National Institutes of Health (NIH) to formulate specific guidelines intended to minimize the risk of SIV transmission to humans.


Originally reported in 1985, the first isolate from a rhesus macaque was called simian T-lymphotropic virus III (STLV-III) (Daniel et al.). Viral isolates have since been obtained from several species of nonhuman primates including African green monkeys (Ohta et al., 1988), sooty mangabeys (Fultz et al., 1986), pig-tailed macaques (Benveniste et al., 1986), and stump-tailed macaques (Lowenstine et al., 1987). Limited studies of wild-caught African green monkeys from Central Africa indicate a seroprevalence of approximately 30-50%, apparently without associated immunodeficiency disease. The seroprevalence of SIV among rhesus monkeys in captive colonies (whether from natural infections or interspecies transmission) appears to be low (i.e., 0-1%) (Daniel et al., 1988). In contrast, captive sooty mangabeys may have seroprevalence rates as high as 80% (McClure, personal communication). The prevalence of SIV infection among many other nonhuman primate species is unknown.

In rhesus monkeys and other susceptible nonhuman primate species (e.g., pig-tailed macaque, crab-eating macaque), SIV infection leads to a chronic wasting disease syndrome with depletion of CD4 (T4) lymphocytes and lymphadenopathy. The clinical course of this infection in monkeys, like that of AIDS in humans, is complicated by opportunistic infections (King, 1986). SIV also causes a primary encephalopathy with many of the features of HIV-associated encephal- opathy (Ringler et al., 1988). Therefore, SIV infection is an important animal model of AIDS.

SIV proteins, especially the viral core proteins (i.e., p24, capsid protein), are antigenically related to HIV-1 proteins (Kanki et al., 1985). Some SIV isolates, however, are antigenically more related to HIV-2 than to HIV-1 by cross-reactivity of viral capsid and envelope proteins. SIV isolates that have been molecularly cloned share approximately 75% of their genomic sequences with HIV-2 and approximately 30% with HIV-1 (Chakrabarti et al., 1987). SIV isolates are clearly distinct from Type D primate retrovirus (i.e., simian retrovirus 1) that also causes a form of chronic wasting immunodeficiency disease in several primate species (Heidecker et al., 1987). Also, SIV is distinct from simian T-cell lymphotropic virus type I (STLV-I), which shares extensive genomic sequences with human T-lymphotropic virus type I and is associated with T-cell lymphomas in nonhuman primates (Watanabe et al., 1985).

SIV can be isolated from a variety of tissues and body fluids``including blood, plasma, cerebrospinal fluid, and parenchymal tissues``of infected nonhuman primates. Limited data exist concerning the presence or concentration of virus in semen, cervical secretions, saliva, urine, breast milk, and amniotic fluids of experimentally or naturally infected nonhuman primates. However, the virus apparently is rarely isolated from semen, urine, and saliva despite repeated attempts at isolation (M. Daniel, N. Lerche, personal communication). There is no evidence to indicate that SIV is transmitted by the respiratory route (N. Lerche, H. McClure, M. Daniel, personal communication).

The cell tropism of SIV in culture depends partially on the strain of virus propagated and conditions of cell culture. Strains of SIV have been successfully cultured in human lymphocyte cell lines (e.g., HuT 78, HT, CEMx174) and in primary human and nonhuman primate peripheral blood leukocyte cultures (Kannagi, Yetz, & Letvin, 1985). SIV appears to be primarily tropic for CD4 (T4)-positive leukocytes and has not been successfully propagated in B-lymphocyte cell lines (e.g., Raji). SIV antigen has been demonstrated by immunohistochemical methods in lymph node sinus histiocytes, macrophages, and giant cells (Ward et al., 1987), as well as in macrophage-derived cells in brain tissue from diseased monkeys (Ringler et al., 1988).

Limited data exist concerning the reactivation of Herpesvirus simiae (B virus) or other latent infectious agents in SIV-infected macaque monkeys. However, all macaque monkeys not proven to be free of B virus infection, regardless of SIV infection status, should be regarded as infected with B virus and handled according to published guidelines (CDC, 1987). The routine screening of macaques for evidence of B virus infection or SIV infection is not recommended. However, in situations in which studies may cause immunosuppression (e.g., during experimental SIV infections), the investigator may elect to determine the infection status of the animals because B virus shedding may be enhanced in infected animals.

Evaluating the Risk of SIV Transmission to Humans

The risk, if any, of human infection with SIV has not been defined. However, since SIV shares many characteristics with HIV, many of the same biosafety precautions are indicated. No serologic or virologic evidence of infection in humans exists; specific precautions in handling SIV are based on recommendations developed for HIV and other lentiviruses. No licensed tests exist for serologic evaluation of humans exposed to SIV, which complicates medical surveillance and investigations of the virus infection following exposure to SIV. In addition, the antigenic cross-reactivity between SIV and HIV may complicate testing of exposed humans.

However, standardized serologic procedures that test for SIV antibody are used in laboratories performing research with the virus. Recently, a protein unique to SIV and HIV-2 (product of gene vpx) was used as antigen in a serologic test that may allow easier distinction between HIV-1 and SIV antibodies (Henderson et al., 1988). Furthermore, gene amplification (i.e., polymerase chain reaction) may allow differentiation of specific virus gene sequences directly from specimens obtained from exposed persons. Based on these events, development of specific and sensitive tests is under way.

Guidelines to Prevent SIV Infection in Laboratory Workers and Animal Handlers

Exposure Concerns. In the laboratory, SIV must be presumed to be present in all SIV cultures, in all materials derived from such cultures, in all specimens from SIV-antibody-positive nonhuman primates, and in/on all equipment and devices coming in contact with these materials. In this setting, the skin (especially when scratches, cuts, abrasions, dermatitis, or other lesions are present) and mucous membranes of the eye, nose, and mouth should be considered as potential pathways for virus entry; contact of these sites with SIV-containing materials should be considered an exposure to SIV.

Biosafety Levels. Biosafety level (BSL) 2 standards and special practices, containment equipment, and facilities, as described in the CDC/NIH publication Biosafety in Microbiological and Biomedical Laboratories (1984), are recommended for activities involving all clinical specimens, body fluids, and tissues from SIV-infected primates. In laboratories maintaining BSL 2, personnel must have documented specific training in handling primate retroviruses, and the laboratory must have limited and properly secured access and written standard operating procedures for techniques in which SIV is used. Procedures involving cultures of SIV should be conducted in biological safety cabinets or other physical containment equipment.

Inoculation Precautions. In the research laboratory, inoculation of SIV-containing material represents an important potential route of exposure to SIV in humans. The use of syringes, needles, glass, and other sharp objects should be avoided, but when their use is essential, needles and disposable cutting instruments should be discarded after use into a lidded puncture-resistant container located in the work area. Needles should not be resheathed, bent, broken, removed, or otherwise manipulated by hand.

Gloves. Latex or vinyl gloves should be worn by all personnel engaged in activities that may involve direct skin contact with infectious specimens, cultures, or tissues. Gloves should not be washed or disinfected for reuse; reuse of such gloves may cause "wicking" (i.e., enhanced penetration of liquids through undetected holes in the glove) or deterioration of the gloves. When gloves have become visibly contaminated, they should be carefully removed and, after the hands are washed, replaced with a fresh pair of gloves. Handwashing with soap and water immediately after infectious materials are handled and work is completed, even when gloves have been worn, should be routine practice.

Clothing. Laboratory coats, gowns, or uniforms should be worn by laboratory workers when engaged in any work involving SIV or materials known or suspected to contain SIV. Clothing that becomes contaminated with SIV or SIV-containing materials should be decontaminated before being laundered or discarded. Clothing can be decontaminated by extensive soaking of the garment with chemical disinfectants (e.g. 1 to 10 dilution of household bleach).

Aerosol Control. Although aerosol transmission of SIV has not been demonstrated, the generation of aerosols, droplets, splashes, and spills should be avoided. A biological safety cabinet should be used for all procedures that might generate aerosols or droplets and for all infected cell culture manipulations. When centrifuging infected materials, centrifuge containers with safety caps that are designed to contain aerosols (in the event of spillage) should be used. When cell sorters are used, plastic shielding or other containment devices should be used to reduce exposure to infectious droplets.

Contaminated Virus Preparations. During the propagation of SIV in the research laboratory, manipulation of concentrated virus preparations or conduct of procedures that may produce aerosols or droplets should be performed in a BSL 2 facility, with additional practices and containment equipment recommended for BSL 3 (CDC, 1984). These practices should include wearing closed-front surgical-type gowns, masks and protective eyewear or face shields, and latex or vinyl gloves that extend to cover the wrist and sleeves of the surgical gown. Activities involving large-volume production or manipulation of highly concentrated SIV should be conducted in a BSL 3 facility, using only BSL 3 practices and equipment. All discarded cultures and laboratory supplies used in experimental manipulations of cultures should be autoclaved before disposal.

Decontamination. The susceptibility of SIV to chemical disinfectants has not been defined. Work surfaces, however, should be decontaminated daily with commercially available chemical disinfectants such as sodium hypochlorite solution 10% (1 to 10 dilution of household bleach), ethanol 70-85%, or ethanol-iodine complex 2%. These effectively inactivate HIV (Martin, McDougal, & Loskoski, 1985; Resnick et al., 1986). Prompt decontamination of spills (immediate absorption and control of the spill and soaking of the contaminated area with chemical disinfectant) should be standard practice. Gloves should be worn when cleaning up such spills. The use of plastic-backed absorbent padding to control spillage during manipulation of cultures or other SIV-containing fluids should be encouraged.

Animal Biosafety Levels. Animal BSL 2 practices, containment equipment, and facilities are recommended for activities involving nonhuman primates or any animals experimentally infected or inoculated with SIV. Animal-care personnel, investigators, technical staff, and other persons who enter animal rooms should wear coats, protective gloves, coveralls or uniforms, and, as appropriate, face shields or surgical masks and eye shields to protect the skin and mucous membranes of the eyes, nose, and mouth.

Handling SIV-Infected Nonhuman Primates. Nonhuman primates experimentally infected with SIV may have other primary, as well as opportunistic, pathogens in their body fluids and tissues. Thus, laboratory workers and animal handlers should follow accepted BSL 2 practices at all times to prevent inadvertent exposure to agents that may be present in clinical specimens or body fluids. All macaque monkeys not known to be free of Herpesvirus simiae (B virus) should be regarded as infected and handled according to published guidelines (CDC, 1987).

Personnel Training. Primary investigators, other scientific personnel, and other persons who handle nonhuman primates used in SIV research should be trained in proper methods of animal restraint and use of protective clothing. Animal handlers should be familiar with various drugs routinely used for providing chemical restraint and with proper procedures for administering medications. All persons engaged in research involving nonhuman primates should be specifically trained in the natural history of SIV infection. Particular attention should be given to the need to wear protective clothing to prevent mucous membrane contact with potentially infectious material, particularly animal blood from an SIV-infected nonhuman primate. Caution should be emphasized during venipuncture procedures or the administration of injections to nonhuman primates involved in SIV research. Intravenous injections of nonhuman primates should be done while the animal is anesthetized and should be administered through a plastic or teflon catheter with syringes fitted with interlocking connectors.

Medical Surveillance. A licensed test specific for SIV antibody is not yet available. Standardized serologic procedures to identify SIV antibody are used in laboratories performing research with the virus. A medical surveillance program should be in place in all laboratories that test specimens, conduct research, or produce reagents involving SIV. The nature and scope of the surveillance program will vary by institutional policy and applicable local, state, and federal regulations (U.S. Departments of Labor & of Health and Human Services, 1987). Laboratories performing research with SIV should initiate a program to store serum from laboratory workers. Serum specimens should be collected at 6-month intervals and stored. Routine testing of the serum is optional but, if performed, should be done using standardized serologic procedures in qualified laboratories.

Human Exposure to SIV. If a laboratory worker has a parenteral, skin, or mucous membrane exposure to blood, body fluids, or virus culture material from nonhuman primates, the source material should be identified and, if possible, tested for the presence of SIV. All wounds incurred from SIV-infected nonhuman primates or from SIV-contaminated instruments hould be cleansed with soap and water. Such incidents should be reported to the animal-care supervisor and/or laboratory supervisor and recorded in an accident report log. If the source material is positive for SIV antibody, virus, or antigen, or unavailable for examination, the worker should be counseled regarding the risk of infection and evaluated medically. The worker should be advised to report and to seek medical evaluation for any acute febrile illness that occurs within 12 weeks after the exposure. Medical evaluation should include examination for serum antibody against SIV. Seronegative workers should be retested 6 weeks after the exposure and periodically thereafter (e.g., 12 weeks and 6 months after exposure). All institutions should establish written policies regarding the management of laboratory exposure to SIV; such policies should deal with confidentiality, counseling, and other related issues. The lack of data concerning the potential transmission of SIV between humans does not allow for specific recommendations concerning behavior changes in a person confirmed seropositive for SIV. However, an SIV-positive person should not donate blood.

Postexposure Treatment. No effective prophylactic treatment for SIV exists; research is needed in animals concerning postexposure prophylaxis (e.g., immune globulin, antiviral therapy). Data from such research may be useful in future exposures of humans to SIV. -- [From Morbidity and Mortality Weekly Report, 37, 1988, 693-694, 699-704.]

Research Reports

Pulmonary Hypertension

A newly discovered animal model for pulmonary hypertension, based on naturally occurring pulmonary vascular disease in the stumptailed macaque (Macaca arctoides) , may be helpful in developing biochemical markers for early detection of the disease in humans, according to Dr. Kenneth M. Weesner of the Bowman Gray School of Medicine in Winston-Salem, NC. An appropriate animal model for human pulmonary vascular disease is critically needed, because diagnosis often comes after the disorder is far advanced and perhaps irreversible. The cause of primary pulmonary hypertension is completely unknown. This disease is progressive and eventually causes severe symptoms, although it may be clinically silent for many years.

A study of the pulmonary circulation of stumptailed macaques revealed that nearly one-third of 63 animals had severe medial thickening of pulmonary arteries that was not due to a congenital heart defect. Hemodynamic studies of 29 live animals of different ages revealed that 8 had elevated pulmonary artery pressure, 10 had normal pressure, and 11 had intermediate pulmonary pressure. Those with elevated pulmonary artery pressure had a blunted increase in pulmonary pressure compared to those with normal pressure, when exposed to hypoxic conditions which cause constriction of the pulmonary artery. The pulmonary hypertension seen is not severe enough to warrant trials of therapeutic measures.

"The most crucial research question involving this colony is a biochemical marker. There is some evidence that platelet activation may lead to the increased pulmonary artery pressure that we are seeing, both in monkeys and in humans," Dr. Weesner says. "This may serve as a biological marker that we can use in the early stages of the disease to identify people who can't be identified hemodynamically or by echocardiography."

If vasoconstriction is involved, it may be possible to develop biological and biochemical markers for pulmonary hypertension using various vasoactive mediators. Echocardiography can be used to detect pulmonary hypertension in humans, but because the disease may be silent the dilemma of which asymptomatic patients to test remains. Biological markers also may make the stumptailed macaque model useful for evaluating prospective treatments for pulmonary hypertension.--From a report by Jonathan Adams in the Research Resources Reporter, November, 1988, 12[11], 9-10.

False-Positive AIDS Tests

The enzyme-linked immunosorbent assay, ELISA, a serum screening test widely used for detection of antibodies to HIV, the human immunodeficiency virus that causes acquired immune deficiency syndrome (AIDS), can produce a high rate of false-positive results in testing certain species of African monkeys. Researchers at the California Regional Primate Research Center (PRC) in Davis suggest that a reaction between natural antibodies and cellular protein contaminants of preparations of viral antigens might be responsible for the high rate of false-positive results and may mask some true-positives.

"ELISA testing is a good method of screening for antibodies, but it is imperative to verify positive ELISA results with a test that is more specific, such as the Western blot," says Dr. Niels C. Pedersen.

Approximately one-fourth of the sera from 526 old-world primates representing 50 different species of monkeys tested positive by the ELISA for antibodies to 3 different retroviruses. The viruses were human T-lymphotropic virus I (HTLV-I), which causes T cell leukemia; HIV; and simian retrovirus type I (SRV-1, a type D retrovirus that also causes simian AIDS). This high incidence of positive responses prompted the investigators to retest the ELISA positives by the Western blot method. Only 20% of those retests were positive.

Six species had the highest concentration of false-positive reactions: Mandrillus sphinx (mandrill), Macaca fascicularis (crab-eating Macaque), M. silensus (lion-tailed macaque), Cercopithecus aethiops (African green monkey), Cercopithecus neglectus (DeBrazza's guenon), C. cephus (moustached guenon), and Miopithecus talapoin (talapoin). Patterns of false-positive reactions were identical in the six species. In other tests, the sera reacted positively to nonretroviruses and cellular debris, suggesting that the sera reacted with cellular material that contaminated the viral protein preparations.

"Some species of animals have a lot of nonspecific antibodies, and it is only by doing the next step, Western blot testing, that you can determine if the ELISA positives are specific or nonspecific," says Pederson. He adds that Western blot testing, although more accurate than ELISA and other available tests, is partly subjective and has quality-control limitations. He feels that more specific and objective approaches need to be developed for even better retrovirus antibody testing.--From a report by Barbara J. Proujan in the Research Resources Reporter, September, 1988, 12[9], 9-12.

Male Rhesus Monkey's Unusual Behavior: Interspecies Adoption

Victor E. Collazo
Caribbean Primate Research Center

The Caribbean Primate Research Center maintains a large number of rhesus monkeys (Macaca mulatta) in harem social groups. Several times, the sires have shown paternal behavior towards their own offspring in these social groups, going as far as temporarily adopting infants. The sire E411, a 12-year-old male, housed with 3 adult females and 2 yearlings in a 40 sq-m concrete pen, expressed this paternal behavior beyond the limits of its own progeny.

One morning, a caretaker noticed that E411 was carrying a live infant. To his surprise, after closer observation, the employee discovered that the "infant" was not a monkey, but an approximately three-week-old cat which apparently had wandered inside the corral and was caught (or adopted) by E411. A relatively large number of feral cats inhabit the proximities of the Center, facilitating the occurrence of this unusual event. The intruder was treated very gently and showed no signs of abuse from its "foster father." The adult male rhesus held the kitten against his chest most of the time (see Figure 1), but for quadrupedal walking, carried it in his mouth, holding it by the nape of the neck.

The male rhesus kept the young cat in this way until it was removed a day later by the caretakers, to prevent the kitten's death from starvation.

Figure 1: E411 and kitten.

This is the first documented case of interspecies adoption in this Center that involves an adult male. The other case (Martinez & Kessler, 1979) was of an adult female who adopted a live feral rat after the death of her newborn infant.

Chimpanzee Sperm Bank

Kenneth G. Gould, chief of reproductive biology at Yerkes Regional Primate Center, has established the world's first sperm bank for chimpanzees, and says he has indisputable proof that it works``a female chimp named Alice who is three months pregnant. For more than 3 decades, scientists have known how to freeze human and cattle sperm successfully, but the formulas they used didn't prevent ice crystals from destroying chimpanzee sperm. Dr. Gould began experimenting with various mixtures and freezing rates in an attempt to prevent formation of ice crystals. Eventually he found that chimp sperm had to be frozen more slowly than other species, and also had to be treated with glycerol. Experiments indicate that about 60% of the spermatozoa survive, compared to about a 70% survival rate in cattle sperm banks. Ten females have each been artifically inseminated one time with previously frozen sperm, and one is pregnant and past the time period when spontaneous abortions in chimps are common. A second female may be pregnant.

The new sperm bank will help scientists preserve one of medicine's most valued research animals, which are a threatened species that no longer can be legally captured in the wild. It will help breeders maintain a genetically diverse population of captive chimps in the United States and give scientists a model for developing sperm banks for other primates like gorillas, which are even closer than chimps to extinction in the wild. -- From an article by Hal Straus in The Atlanta Constitution, October 25, 1988.

Lawsuit Against U.C. Dismissed

On August 18, an Alameda County Superior Court judge dismissed a suit brought against the University of California system by Animal Allies, formally the Sacramento branch of People for the Ethical Treatment of Animals. The activists sued to gain access to the university's ten animal care and use committees. The judge ruled that the UC committees are not subject to the state's open meeting law. Therefore, the committees do not have to be open to the general public. Animal Allies plans to appeal the court's decision. -- From NABR Update, 9[19], September 26, 1988.

Pickett Retires

Dr. Betty H. Pickett, Director of the Division of Research Resources (DRR) for the past 6 years, retired on October 1 after 31 years of Federal service. Her NIH career began in 1958 as Executive Secretary of the Behavioral Sciences Study Section in the Division of Research Grants. Later, she was appointed Chief of the Cognition and Learning Section, Division of Extramural Research Programs, NIMH. From 1968 to 1978, she served as Deputy Director of that Division, receiving the DHEW Superior Service Award for her work.

In 1979, Dr. Pickett became Deputy Director, and later Acting Director, of NICHD. In 1982, she was appointed by Dr. James P. Wyngaarden, NIH Director, as Director of the DRR--the component of NIH responsible for creating, developing, and making available a broad array of centers, resources, and institutional support required by the biomedical research activities of the NIH and other research components of the Public Health Service.

Dr. Pickett plans to divide her time between her homes in Washington, DC and Surry, ME. Dr. Robert A. Whitney, Jr., Director of the Division of Research Services, has been named Acting Director of DRR by Dr.Wyngaarden, who plans to amalgamate the two divisions.


The new Governing Board of the International Council for Laboratory Animal Science (ICLAS) and a number of observers met September 17-18 in Liestal, Switzerland. Scholarships were awarded to students from Nigeria, Kenya, and Uganda, and the report of a scholarship holder from Poland was accepted. Secretary General Osmo Hänninen distributed a draft plan for the East African Regional Laboratory Animal Center, which had been prepared on the basis of discussion with Kenyan experts. Past Secretary General Ramsay Hovell reviewed the present phase of work in the preparation of a manuscript for the ICLAS/WHO guidelines for laboratory animal services for developing countries. He was authorized to finalize the editing. It was recommended that a special course on laboratory animal science be organized in Brazil before or after the XXIV World Veterinary Congress, to be held there in 1991. The East African Regional Symposium of Laboratory Animal Science, which will be held in November, 1989, will be the main meeting of ICLAS this year.

NIH Briefs Congressional Aides

The National Institutes of Health (NIH) sponsored a presentation entitled "Why Biomedical Research with Animals is Essential" for congressional aides and staff on June 17, 1988 in Washington, DC. Speakers included Dr. Franklin M. Loew, dean of the Tufts University School of Veterinary Medicine (whose statement is printed in the Fall, 1988, issue of ILAR News) , Dr. William F. Raub, deputy director of NIH, and Dr. Steven A. Rosenberg, chief of the Surgery Branch, National Cancer Institute, NIH.

Costs for New Animal Rules

Regulations on amendments to the Animal Welfare Act of 1985 are expected to be released soon from the Office of Management and Budget, where they have been under review since July. According to the Agriculture Department's Animal and Plant Health Inspection Service (APHIS), the long-awaited "Part 3" of new regulations would cost research institutions about $111 million in capital expenditures on primate facilities.

APHIS's proposed primate rules draw heavily on recommendations from an advisory committee that included ten researchers. They contain a new section on social housing, revise specifications for "primary enclosures," and spell out ways to enrich cage environments. A draft of the proposed rules, described in Science (1988, 242, 662-663) in a "News and Comments" article by Constance Holden, says that primates are "social beings in nature and require contact with other nonhuman primates for their psychological well-being." Therefore, they must be housed with others, in pairs or groups, "whenever possible and consistent with" their health, safety, and well-being.

New prescriptions for cage sizes are set for each of seven categories by weight. They correspond for the most part with recommendations in the NIH "Guide for the Care and Use of Laboratory Animals." The rules state that "the physical environment in primary enclosures must be enriched by providing means of expressing species-typical activities." Special enrichment measures must be designed for juveniles, primates showing signs of psychological distress, and animals used in research that does not involve physical activity.

According to the regulatory impact analysis, a large part of the additional outlay of $111 million will be for new cages. The total number of cages needing replacement is estimated at over 59,000. New recreational equipment is estimated at $100 to $1000 per cage. In addition, 429 facilities are said to need to add building space for primate housing, and 264 to require renovations. How and by whom the costs of all the changes will ultimately be borne remains an unanswered question. The only federal money specifically targeted for animal facilities improvement is a program in NIH's Division of Research Resources. The fiscal 1989 budget for this is $11.6 million, which requires matching funds from the recipient.

Animal Models

*Naturally occurring chronic gastritis and C pylori infection in the Rhesus monkey: A potential model for gastritis in man. Baskerville, A. & Newell, D. G. (Public Health Laboratory Service, Centre for Applied Microbiology and Research, Porton Down, Salisbury, Wiltshire SP4 0JG, England). Gut, 1988, 29, 465-472.
. . Histological examination of the stomachs of 11 rhesus monkeys at autopsy showed chronic gastritis in a high proportion of all ages. Gastric Campylobacter-like organisms apparently identical to human C. pylori were cultured and/or detected immunohistologically in several animals. Two of 5 cynomolgus monkeys examined had gastritis, which may be associated with the presence of C. pylori. Ten baboons examined did not have gastritis, nor was C. pylori cultured from their stomachs.

Animal Welfare

*Experts ponder simian well-being. Holden, C. Science, 1988, 241, 1753-1755.
. . A report on the conference on psychological well-being of captive primates held in Boston this September, under the sponsorship of Tufts University, the New England Primate Center, and the University of Massachusetts, with a grant from the American Psychological Association.


*Social factors influencing choice of food source in a captive group of chimpanzees (Pan troglodytes) . Gust, D. A. (Yerkes Regional Primate Research Center Field Station, Emory Univ., 2409 Taylor Rd., Lawrenceville, GA 30243). American Journal of Primatology, 1988, 16, 81-87.
. . A group of 16 chimpanzees maintained in a large, outdoor compound chose among three feeding stations that were spatially separated and located along the periphery of the compound. The study provides quantitative data supporting postulations that factors such as social relationship, kinship, and estrous cycle stage affect the composition of groupings of chimpanzees at feeding stations, and the results are consistent with field observations.

*Preliminary report on the activity cycle and diet of the red-bellied lemur (Lemur rubriventer) in Madagascar. Overdorff, D. (Duke Univ. Primate Center, 3705 Erwin Rd., Durham, NC 27705). American Journal of Primatology, 1988, 16, 143-153.
. . Data were collected on diet, patterns of activity, and group composition of red-bellied lemurs in a southeastern rainforest of Madagascar during June and July 1986. In June, the group's major food resource was fruit, and they maintained a strict diurnal activity cycle. In July, they fed on flowers (80%), fruits (10%), and leaves (10%), and were nocturnal as well as diurnal. The transition from a diurnal to a random, 24-hour activity pattern may be an adaptive strategy to avoid predation by diurnal raptors.

*Sexually dimorphic transitions revealed in the relationships of yearling rhesus monkeys following the birth of siblings. Holman, S. D. & Goy, R. W. (MRC Neuroendocrine Development & Behaviour Group, AFRC Inst. of Animal Physiology, Babraham, Cambridge, CB2 4AT, U.K.). International Journal of Primatology, 1988, 9, 113-133.
. . Social interactions of 1-year-old animals 6 weeks before the birth of siblings were compared with interactions occurring 6 weeks after. Among yearling females, no dramatic changes in interactions with their mothers or with other group members were detected, but yearling males refocused their attentions away from their mothers and toward other, often unrelated members of the group.

*Maternal time budgets of gelada baboons. Dunbar, R. I. M. & Dunbar, P. (Dept. of Anthropology, University College London, Gower St., London WC1E 6BT, U.K.). Animal Behaviour, 1988, 36, 970-980.
. . Data from gelada baboons, Theropithecus gelada, were used to evaluate J. Altmann's model of maternal time budgets. The results provide substantial confirmation of the model's general principles: the time that a female devoted to feeding increased with the age of her infant roughly in line with the model's predictions. The results suggest that Altmann's assumption that the additional demand for feeding time is taken out of social time is only partially correct. Social time was conserved as far as possible, with extra feeding time being taken out of resting time until much of the available resting time was used up. Then the female released some of her social time, but still sought to preserve those social relationships that are most important to her long-term reproductive interests.

*Resolution of aggressive conflicts by immature long-tailed macaques Macaca fascicularis. Cords, M. (Ethologie und Wildforschung, Zoologisches Inst., Univ. Zürich-Irchel, Winterthurerstrasse 190, 9057 Zürich, Switzerland). Animal Behaviour, 1988, 36, 1124-1135.
. . The behavior following aggressive interactions differed from that following friendly or neutral control interactions among unrelated immature male M. fascicularis. The behavior characterizing encounters between former opponents differed in the two situations, with more affiliative interactions post-conflict. The pattern of interactions between former opponents is interpreted as a repair mechanism for relationships strained by aggression.

*Experimental matrilineal inheritance of rank in female Japanese macaques. Chapais, B. (Dépt. d'Anthropologie, Univ. Montréal, C.P. 6128, Montréal, PQ H3C 3J7, Canada). Animal Behaviour, 1988, 36, 1025-1037.
. . In a group of 17 Japanese macaques comprised of three families with similar age-sex compositions, experimental female subgroups were formed such that in each of them a female (dependent) was given more alliance power than a dominant target. Results indicate that in each of the subgroups that was tested the dependent female inherited the rank of her ally (mother or older sister) above same-age or older targets. The fact that females who were given more alliance power did not solicit their ally, or challenge the target females, before they were aided by their ally suggests that aggressive interventions are the primary mechanism of rank inheritance. The role and dynamics of the recognition of alliances in the establishment of rank relationships are discussed.

*Experimental rank reversals among peers in Macaca fuscata: Rank is maintained after the removal of kin support. Chapais, B. & LaRose, F. (Address same as above). American Journal of Primatology, 1988, 16, 31-42.
. . Experimental subgroups were formed by placing together peers from different families and a single kin (ally) of one subordinate peer (mother or older sister). These experiments induced a series of rank reversals whereby the subordinate peer, whose ally was present, outranked the dominant peers. Following the rank reversals, the ally of the newly dominant peer was removed and the peers left together. All five experimentally inverted rank orders of peers remained stable.

*Individual and group effects on early caregiver-infant relationships in red-bellied tamarin monkeys. Pryce, C. R. (Dept. of Anthropology, University College London, Gower St., London WC1E 6BT, U.K.). Animal Behaviour, 1988, 36, 1455-1464.
. . The relationship between changes in caregiver-caregiver and caregiver-infant behavior was studied during the infants' first month in 10 family groups of red-bellied tamarins with twin infants. Each caregiver initiated carrying by retrieving an infant from another caregiver, and sometimes retained an infant against a retrieve attempt by another caregiver in order to continue carrying it. Results indicate that competition to care for infants has a direct effect on the early development of each caregiver-infant relationship within the family group.

*Mating season effects on mother-infant conflict in Japanese macaques, Macaca fuscata. Worlein, J. M., Eaton, G. Gray, Johnson, D. F., & Glick, B. B. (G. G. Eaton, Dept. of Reproductive Biology & Behavior, Oregon Regional Primate Research Center, 505 N.W. 185th Ave., Beaverton, OR 97006). Animal Behaviour, 1988, 36, 1472-1481.
. . The impact of seasonal mating on the mother-infant relationship during the first year of the infant's life was documented in a confined troop of Japanese macaques. During the weeks in which the mothers were being mounted, negative behavior directed towards the infants increased. As maternal rejections and punishments escalated, the infants displayed regressive behavior. The mother-infant relationship undergoes a period of conflict during the mating season not because the mother is weaning her infant, but because it is to her reproductive advantage to regulate the times in which the infant is allowed to suckle.

*Arbeitsteiliges und kooperatives Problemlöseverhalten in Primatengruppen [Labor-division and co-operation in problem-solving primate groups]. Vössing, A. (Zoologisches Inst. der Univ. Münster, Abt. für Verhaltensforschung). Zoologische Beiträge, 1987, N. F. 31, 305-340.
. . A group of vervets (4 male, 7 female) and a group of lemurs (2 male, 4 female) were daily given a box, containing food and fastened with a variety of latches. One vervet opened the latches and box in 95% of the cases, while 2 lemurs shared 75% of the solutions.

*Changes in the size, composition, and reproductive condition of wild marmoset groups (Callithrix jacchus jacchus) in north east Brazil. Scanlon, C. E., Chalmers, N. R., & Monteiro da Cruz, M. A. O. (Biology Dept., The Open University, Milton Keynes, MK7 6AA, England). Primates, 1988, 29, 295-305.
. . Five groups of Callithrix jacchus jacchus were studied in the field. Group size and composition were similar to that described for other callitrichids, but changes in group membership occurred much more frequently than previously reported. It is argued that marmoset social organization is best studied at the level of the whole population within an area, rather than at the level of the individual group.

*Responsiveness to objects in two social groups of tufted capuchin monkeys (Cebus apella). Visalberghi, E. (Ist. di Psicologia, CNR, Via Aldrovandi, 16b, Roma 00197 Italy). American Journal of Primatology, 1988, 15, 349-360.
. . The responses of two social groups of Cebus apella to novel or familiar objects were examined, both in scarce and abundant conditions. The aim was to obtain a description of capuchins' general norms of behavior toward objects, focusing on the variability across sex/age classes. Sex and age significantly affected the behavioral pattern of interaction with blocks. Dominance did not seem to constrain monkeys' responsiveness.

*Long-term retention of self-recognition by chimpanzees. Calhoun, S. & Thompson, R. L. (R. L. Thompson, Dept. of Psychology, Hunter College, CUNY, New York, NY 10021). American Journal of Primatology, 1988, 15, 361-365.
. . Two young chimpanzees showed retention of self-recognition after 1 year without access to mirrors. The animals had been positive on the Gallup dye test. One year later they were once again anesthetized, marked on the brow and ears, and following recovery, exposed individually to a large mirror. Both demonstrated mirror-oriented mark-directed responses. Time-sample observations of behavior toward the mirror further support self-recognition.

*Inferring patterns of aggression from red howler monkey injuries. Crockett, C. M. & Pope, T. (13034 1st Ave. NE, Seattle, WA 98125-3005). American Journal of Primatology, 1988, 15, 289-308.
. . Thirty-eight percent of 119 howler monkeys, examined at capture, showed scars or other evidence of "damage." Sociobiological costs of aggression in red howlers are difficult to assess because many howlers, despite frequent and severe injury, subsequently survive and reproduce. The authors recommend caution in inferring mortality from injuries, especially when social mobility and emigration out of the study area are common.

*Orangutan diet, range, and activity at Tanjung Puting, Central Borneo. Galdikas, B. M. F. (Orangutan Research and Conservation Project, Tromol Pos 1, Pangkalan Bun, Kalimantan Tengah, Indonesia). International Journal of Primatology, 1988, 9, 1-35.
. . This study focuses on an orangutan population in a swampy lowland area near sea level. The animals were predominantly frugivorous, but the overall variety in their diet was remarkable; 317 different food types have been identified, including fungus, insects, and honey. Contact with other orangutans usually increased a focal animal's day length, day range, and amount of time spent moving. This suggests that foraging alone maximized each orangutan's foraging returns by minimizing the day range traveled. Orangutan solitariness is the result of large body size and of a predominantly frugivorous and opportunistic diet.

*The variable social organization of Hanuman langurs (Presbytis entellus) , infanticide, and the monopolization of females. Newton, P. N. (Animal Ecology Research Group, Dept. of Zoology, Oxford OX1 3PS, England). International Journal of Primatology, 1988, 9, 59-77.
. . Data from 24 wild populations of Hanuman langurs are used to test hypotheses seeking to explain variation in troop structure and the incidence of infanticide. The occurence of infanticide is associated with a one-male troop structure and not with a high density. It is suggested that a one-male troop structure will arise if a male is able to monopolize a group of females, a multimale troop if he cannot.

*A case of offspring desertion by a female chimpanzee and the behavioral changes of the abandoned offspring. Hiraiwa-Hasegawa, M. & Hasegawa, T. (Dept. of Anthropology, Faculty of Science, Univ. of Tokyo, Hongo, Bunkyo-ku, Tokyo, 113 Japan). Primates, 1988, 29, 319-330.
. . This is the first record of an immature chimpanzee (a five-year-old male) abandoned by its emigrating mother, although a similar phenomenon has been reported for gorillas and Hanuman langurs. The abandoned offspring followed an adult male of the group, and that male gave most care to it. The youngster's time spent on grooming others increased, the time spent on being groomed decreased, and the rate of aggression toward him increased after his mother's desertion.


*Psychological well-being of primates in captivity. Novak, M. A. & Suomi, S. J. (Dept. of Psychology, Univ. of Massachusetts, Amherst, MA 01003). American Psychologist, 1988, 43, 765-773.
. . No consensus presently exists in terms of how to define or identify psychological well-being in primate subjects. A strategy is proposed for defining psychological well-being that includes assessment of physical health, comparison with species-normative behavioral repetoires, detection of distress, and evaluation of coping responses. This set of definitions is then used to characterize prototypical primate laboratory environments in terms of fostering psychological well-being. The importance of factors other than housing, such as species-specific characteristics, rearing histories, and phenotypic differences, is also emphasized. It seems unlikely that simple prescriptions will be broadly applicable across the whole range of captive primates.

*Developing effective social and environment enrichment strategies for macaques in captive groups. O'Neill, P. (NIH Animal Center, 22766 Club Hollow Rd., Dickerson, MD 20842). Lab Animal, 1988, 17[4], 23-24, 27-28, 31-36.
. . A group of 17 to 20 rhesus monkeys representing 3 matrilines are free-ranging in a 5-acre enclosure for 8 months in the year, then housed indoors in an enriched playroom interior for the winter. Data was collected to determine what types of activity 4 different age groups engaged in during a 6-week period in winter. The data show both striking differences and similarities among the age groups. Toys and apparatus introduced into the cage environment are not simply alternatives taking the place of social interactions, but rather are tools for redirecting and in some cases enhancing or stimulating social interactions primarily through play.

*Rearing cynomolgus monkeys (Macaca fascicularis) on surrogate mothers with bottle feeding. Timmermans, P. J. A., Röder, E. L., & Kemps, A. M. L. J. (Dept. of Comparative & Physiological Psychology, Univ. of Nijmegen, P. O. Box 9104, 6500 HE Nijmegen, the Netherlands). Laboratory Animals, 1988, 22, 229-234.
. . Fifty-two cynomolgus monkeys were reared in peer groups on surrogate mothers and fed by bottle during the first months of life. A description of the technique of bottle feeding and the structure of surrogate mothers is presented, along with a growth curve. The weight of mother-reared infants stayed within the standard deviation of the mean weight of the artificially-reared subjects.

*The social behaviour of hand-reared siamang at Adelaide Zoo. Parker, S., St. Clair, M., & Wheeler, L. (Reprint requests to D. Langdon, Adelaide Zoo, Frome Rd., Adelaide, SA 5000, Australia). Australian Primatology, 1988, 3[2/3], 3-5.
. . Description of an unsuccessful attempt to introduce two male infant siamangs to a foster mother.

*Food distribution, dominance, and aggressive behaviors in bonnet macaques. Boccia, M. L., Laudenslager, M., & Reite, M. (Dept. of Psychiatry, C-268, Univ. of Colorado Health Sciences Center, 4200 East Ninth Ave., Denver, CO 80262). American Journal of Primatology, 1988, 16, 123-130.
. . This study examines the impact of manipulation of the distribution of food resources in a laboratory-housed group of bonnet macaques to assess the impact of distribution on aggressive behaviors. Food was restricted to a space which allowed access to only one or two individuals at a time or was dispersed throughout the living enclosure to allow universal access in alternating periods. During periods of clumped distribution, the monkeys obtained access to the food in order of their dominance status. In addition, overall levels of aggressive behaviors increased, submissive behavior increased, and play decreased during those periods. These results confirm the findings from field studies indicating increases in agonism with restriction of food resources.

*Formula-fed and breast-fed baboons: Weight growth from birth to adulthood. Glassman, D. M. & Coelho, A. M., Jr. (Dept. of Sociology & Anthropology, Southwest Texas State Univ., San Marcos, TX 78666). American Journal of Primatology, 1988, 16, 131-142.
. . Longitudinal weight data were collected from two groups, each with 11 females and 11 males, of savannah baboons (Papio cynocephalus anubis) for the total period of growth from birth to approximately 8 years of age. One group were fed a standard infant formula by a nursery care technician for the first 18 weeks of postnatal life, while the other was breast-fed by their mothers for an equivalent period of time. After 18 weeks, the animals were removed from either nursery or mother and assigned to one of four age-cohort social groups, each balanced for treatment and gender. No significant weight differences were found between rearing conditions for the initial 15 weeks of growth. However, breast-fed females averaged greater weight at all later ages, and had a slightly more intense adolescent growth spurt than their bottle-fed peers.

*Successful feeding enrichment for captive chimpanzees. Bloomsmith, M. A., Alford, P. L., & Maple, T. L. (Univ. of Texas System Cancer Center, Science Park Veterinary Resources Dept., Rt. 2, Box 151-B1, Bastrop, TX 78602). American Journal of Primatology, 1988, 16, 155-164.
. . Four feeding enrichment procedures were implemented simultaneously on 41 adult chimpanzees in six social groups in the experimental phase of this ABA design study. The procedures were planned to elicit time-consuming, noncompetitive feeding. 270 hours of data were collected over a 6-month period. The barrage of feeding enrichment techniques significantly reduced agonism and abnormal behaviors.


*Madagascar's lemurs: On the edge of survival. Jolly, A. National Geographic, 1988, 174, 132-161.
. . A report, with photographs by Frans Lanting, on conservation efforts on Madagascar.

*Experimental technique for the conservation of private lands. Horwich, R. H. & Lyon, J. (RD 1, Box 96, Gay Mills, WI 54631). Journal of Medical Primatology, 1988, 17, 169-176.
. . A community-based sanctuary for black howler monkeys (Alouatta pigra) has been established on 18 square miles of riverine forest along the Belize River, Belize. It is based on voluntarily signed pledges by subsistence farmers to abide by management plans for their lands. Conservation-education programs which impact favorably on the villagers are being carried out.

*Rain Forest Conservation: A Plea for a More Dynamic, D.I.Y. Approach. W. R. Kingston. [Available from W. R. Kingston, The Old Smithy, Bishops Frome, Worcester WR6 5BA, U.K.]
. . A proposal for carefully controlled commercial and tourist facilities in threatened tropical rain forests, which would simultaneously protect and make self-supporting endangered habitats and species.


*Reversal of chloroquine resistance in malaria parasite Plasmodium falciparum by desipramine. Bitonti, A., Sjoerdsma, A., McCann, P. P., Kyle, D. E., Oduola, A. M. J., Rossan, R. N., Milhous, W. K., & Kavidson, D. E. Jr. (Merrell Dow Research Inst., Cincinnati, OH 45215). Science, 1988, 242, 1301-1303.
. . Desipramine was found to be one of the most effective compounds yet described for the reversal of chloroquine resistance both in vitro and in vivo.

*Relearning the lessons of Herpes B virus: A report for the monkey handler. Cummins, L. B. (White Sands Research Center, 2512 Christina Pl., Alamogordo, NM 88310). Lab Animal, 1988, 17[3], 25-27.
. . Two basic questions are asked: What have we learned from the 1987 Herpes B virus outbreak, and what must we do differently in the future to prevent this rare but serious disease? The most important factor in attending to an exposure is having a procedure in place well in advance of the time it is needed. Until new developments are introduced to reduce exposure to Herpes B virus and to control infections when they occur, we are left with the preventive measures we have relied on for so long``but we must apply them diligently and not become negligent.

*Spontaneous and experimental hepatitis A in Old World monkeys. Shevtsova, Z. V., Lapin, B. A., Doroshenko, N. V., Krilova, R. I., Korzaja, L. I., Lomovskaya, I. B., Dzhelieva, Z. N., Zairov, G. K., Stakhanova, V. M., Belova, E. G., & Sazhchenko, L. A. (USSR Academy of Medical Sciences, Inst. of Experimental Pathology & Therapy, P.O. Box 66, Gora Tapetziya, Sukhumi 384900, USSR). Journal of Medical Primatology, 1988, 17, 177-194.
. . Virologic, serologic, biochemical, and morphological data characterizing spontaneous hepatitis A (HA) in cynomolgus macaques and green monkeys are reported. Experimental HA was induced in macaques as a result of infection with human hepatitis A virus (HAV-h). Disease similar to human HA was induced in cynomolgus macaques by HAV isolates from spontaneously sick rhesus and green monkeys. This experimental model of HA in macaques can be used for vaccine and anti-viral preparation testing.

*Use of BCG vaccines in the control of tuberculosis: A joint statement by the ACIP and the Advisory Committee for Elimination of Tuberculosis. Morbidity and Mortality Weekly Report, 1988, 37, 663-664, 669-675.
. . Immunization with BCG vaccine lowers the risk of serious complications of primary TB in children. However, it is no longer recommended for health care workers or other adults at high risk for acquiring TB infection. In addition, BCG should not be given to perons who are immunocompromised, including those with human immunodeficiency virus infection.

*Cholera vaccine: Recommendations of the Immunization Practices Advisory Committee. Morbidity and Mortality Weekly Report, 1988, 37, 617-618, 623-624.

*Simian AIDS ELISA: Sensitivity, specificity and predictive values based on a comparison with Western blot technique. Spinner, A. & Sutjipto, S. (California Primate Research Center, Univ. of California, Davis, CA 95616). Laboratory Animal Science, 1988, 38, 568-572.
. . One hundred thirty-one rhesus macaques were tested for the presence of antibody against SAIDS type D retrovirus by both ELISA and Western blot techniques. Sensitivity, specificity, and predictive values for the SAIDS ELISA were calculated based on a comparison with Western blot results. Sera was tested from two distinct populations, endemic (71 macaques from a half-acre outdoor corral where SAIDS was first recognized) and control (60 rhesus macaques from both indoor and outdoor areas where the disease was not recognized). ELISA is shown to be a useful screening tool based on its high sensitivity for both populations, providing a rapid and economical way to diagnose and manage SAIDS in captive nonhuman primate colonies.

*Hepatocystis in populations of baboons (Papio hamadryas s.l.) of Tanzania and Ethiopia. Phillips-Conroy, J. E., Lambrecht, F. L., & Jolly, C. J. (Dept. of Anatomy and Neurobiology, Washington Univ., St. Louis, MO 63110). Journal of Medical Primatology, 1988, 17, 145-152.
. . Bloodsmears from 119 yellow baboons (Papio hamadryas cynocephalus) in 6 groups in Mikumi National Park, Tanzania, and from 189 olive (P. h. anubis) , hamadryas (P. h. hamadryas) , and hybrid baboons in three groups in Awash National Park, Ethiopia, showed differing levels of infection with Hepatocystis simiae. 0% to 42% in the Tanzanian groups were carriers of the parasite, but none of the Ethiopian baboons was positive. The remarkable absence of H. simiae in the Ethiopian baboons is believed to be related to environmental factors that exclude transmission in the absence of the Culicoides vector.


*Application of DNA fingerprinting probes to Old World monkeys. Weiss, M. L., Wilson, V., Chan, C., Turner, T., & Jeffreys, A. J. (Dept. of Anthropology, 139 Manoogian Hall, Wayne State Univ., Detroit, MI 48202). American Journal of Primatology, 1988, 16, 73-79.
. . Analysis of tandem-repetitive minisatellite DNA in humans provides great discriminatory power in paternity identification and individualization of tissue samples. The molecular probes used to study these hypervariable loci are here applied to DNA isolated from related animals in four species of Old World monkeys. Probes 33.6 and 33.15 are shown to cross-hybridize with variable minisatellites in Macaca fuscata, M. silenus, Erythrocebus patas, and Colobus guereza. The DNA fingerprint patterns are consistent with germ-line stability and mendelian inheritance. Application of DNA fingerprinting to Old World monkeys thus provides a new tool for identifying parentage and can thereby aid in colony management. The technique can also help to elucidate the role of behavioral factors in evolution. The breadth of applicability in other primates remains to be mapped.

Instruments and Techniques

*Real-time ultrasonic evaluation of the baboon pregnancy: Biometric measurements. Farine, D., MacCarter, G. D., Timor-Tritch, I. E., Yeh, M.-N., & Stark, R. I. (R. I. Stark, Dept. of Pediatrics, Babies Hospital, 622 W. 168th St., New York, NY 10032). Journal of Medical Primatology, 1988, 17, 215-221.
. . Ultrasonic and direct biometric measurements of nine fetal baboons were made during 23 evaluations. Both the femur length and the biparietal diameter were correlated to gestational age. These initial results have facilitated intrauterine surgery. The data presented will help in determining adequate fetal growth and in dating baboon pregnancies.

*Comparison of blood flow parameters measured by Doppler ultrasound and radionuclide techniques in the baboon (Papio ursinus) . Bosman, H., Dormehl, I. C., Hordijk, C., Maree, M., & Hugo, N. (I. C. Dormehl, AEC Inst. of Life Sciences, Faculty of Medicine, Univ. of Pretoria, P.O. Box 2034, Pretoria 0001, South Africa). Journal of Medical Primatology, 1988, 17, 223-231.
. . Ascending aortic blood velocity was measured in the baboon by using continuous wave Doppler ultrasound. The blood flow parameters thus obtained were compared to those by the standardized radionuclide technique. It appears that, due to the anatomical position of the ascending aorta and brachiocephalic trunks in relation to the ultrasound beam, Doppler ultrasound does not provide an accurate method of measuring aortic blood velocity in the baboon.

*A backpack system for chronically instrumented unrestrained baboons. Maclean, J. M., Phippard, A. F., Gillin, A. G., & Horvath, J. S. (Renal Hypertension Unit, Royal Prince Alfred Hospital, Camperdown, NSW 2050, Australia). Australian Primatology, 1988, 3[2/3], 7-8.
. . A system to protect and immobilize exteriorized instruments in conscious unrestrained baboons, while allowing periodical access for experimental work. The backpack has a removable transparent cover, which allows remote inspection of the catheters and their exit sites between the scapulae. A second backpack cover attaches to a flexible stainless steel tether, which carries catheter extension tubing or electrical connections to recording equipment during experimental sessions. A plate located inside the backpack between the base and cover provides a mounting point within the backpack on which catheter ends and electrical connections can be fixed.

*Spider monkey home ranges: A comparison of radio telemetry and direct observation. Fedigan, L. M., Fedigan, L., Chapman, C., & Glander, K. E. (Dept. of Anthropology, Univ. of Alberta, Edmonton, Alberta, Canada). American Journal of Primatology, 1988, 16, 19-29.
. . The ranging patterns of 2 male and 5 female spider monkeys were studied with the use of radio telemetry in Santa Rosa National Park, Costa Rica. The probability of encountering a radio-collared spider monkey in a 3-hour search using radio telemetry (0.91) was much greater than using a visual search (0.20), and telemetric data resulted in a larger estimate of mean home range size than did observational data, when all subjects were compared. However, the difference appeared to be owing to the presence of male ranges in the telemetric, but not the observational, data. When comparison was made between radio-tracking and observation results for range size for adult females only, there was no significant difference.

Pharmacology & Anesthesia

*Alphaxolone-alphadolone for anesthesia of squirrel monkeys of different ages. Lögdberg, B. (Inst. of Environmental Health, Univ. of Lund, Sölvegatan 21, S-223 62 Lund, Sweden). Journal of Medical Primatology, 1988, 17, 163-167.
. . This report describes 75 cases of reliable 1-2 hour surgical anesthesia of newborn to adult squirrel monkeys, with rapid induction and recovery, using a single intramuscular dose of alphaxolone-alphadolone (doses between 11.5 and 30 mg/kg body weight).

*Obstetric analgesia and infant outcome in monkeys: Neonatal measures after intrapartum exposure to meperidine or alfentanil. Golub, M. S., Eisele, J. H., & Donald, J. M. (California Primate Research Center, University of California, Davis, CA 95616). American Journal of Obstetrical Gynecology, 1988, 158, 1219-1225.
. . Neurobehavioral evaluations were conducted in neonatal monkeys (Macaca mulatta) exposed to narcotic analgesics during labor through their dams. They were compared to controls whose dams received no analgesic. Drug-exposed infants showed neurobehavioral effects over the first 3 days of life. Drug exposure was also associated with increased elicited muscle tone early in the neonatal period and earlier maturation of sitting, standing, and walking, as well as lower hematocrits and an earlier onset of linear growth rate as reflected in body weight. No qualitative or quantitative differences were noted between the two drug treatments.


*A study of postnatal appendicular skeletal maturation in captive-born squirrel monkeys (Saimiri boliviensis). Galliari, C. A. (Centro Argentino de Primates, CONICET, Casilla de Correo 145, (3400) Corrientes, Argentina). American Journal of Primatology, 1988, 16, 51-61.
. . This study is based on a mixed longitudinal radiographic sampling of appendicular bones in 82 captive-born squirrel monkeys. All appendicular ossification centers had appeared radiographically by 17 weeks of age, and epiphyseal fusion was complete by 47-53 months of age. No statistically significant differences were found between the sexes in comparisons carried out at birth and at 6 and 8 months of age.

*Elevation in plasma glucagon levels in response to stress in squirrel monkeys: Comparisons of two subspecies (Saimiri sciureus boliviensis and Saimiri sciureus sciureus) . Meyers, B. A., Mendoza, S. P., & Cornelius, C. E. (S. P. Mendoza, California Primate Research Center, Univ. of California, Davis, CA 95616). Journal of Medical Primatology, 1988, 17, 205-214.
. . Bolivian and Brazilian squirrel monkeys were captured and restrained to determine patterns of glucagon and glucose response. In both subspecies, plasma glucagon and glucose levels rose rapidly in response to restraint procedures; glucagon levels in boliviensis and glucose levels in both subspecies returned to basal values in 15 minutes. The magnitude of the glucagon and glucose responses differed significantly between the subspecies.

*Variation in rates of activity and inhibition of serum cholinesterase among anthropoid primates. Breed, R. T. & Jolly, C. J. (C. J. Jolly, Dept. of Anthropology, New York Univ., New York, NY 10003). International Journal of Primatology, 1988, 9, 97-112.
. . Cholinesterase activity in the plasma of 5 hominoid and 5 cercopitheciod species was measured and characterized by profiles of inhibition by dibucaine and NaF. Chimpanzees and gorillas strongly resemble humans, and differ from other hominoids and cercopithecoids, in patterns of dibucane and fluoride resistance and relative activity toward various thio esters. "Silent" cholinesterase phenotypes of probable veterinary significance, and analogous to a rare human variant, are apparently normal in some catarrhine species and are present as a polymorphism among orangutans and lion-tailed macaques.

*Endogenous rhythms in the succession of sleep-wake stages in Microcebus murinus. Petter-Rousseaux, A. & Barre, V. (CNRS, Lab. d'Anatomie Comparée, 55 rue Buffon, 75005 Paris, France). International Journal of Primatology, 1988, 9, 147-163.
. . Sleep-wake stages were studied by means of EEG recordings in 3 female Microcebus maintained under dim red light for 2 to 12 months and in a female maintained in constant bright light first for 1 month, then for 4 months. A circadian rhythm was apparent in all cases. In addition, the reduction of the alert-wake state in winter and its large increase in summer hints at a circannual rhythm.

*Prenatal growth in the cynomolgus and rhesus macaque (Macaca fascicularis and Macaca mulatta) : A comparison by ultrasonography. Tarantal, A. F. & Hendrickx, A. G. (California Primate Research Center, Univ. of California, Davis, CA 95616). American Journal of Primatology, 1988, 15, 309-323.
. . Observations during the embryonic and fetal periods in cynomolgus and rhesus macaques have been compared with diagnostic ultrasound. Results indicate no significant differences in size during the embryonic and early fetal periods, but a greater acceleration of growth in the rhesus begins at approximately 100-110 gestational days. Analysis of embryonic and fetal heart rates indicate no differences between the two species. Normal predictive values for a variety of growth parameters including gestational sac, greatest length, biparietal diameter, and femur length have been calculated by multiple regression analysis. These charts have proven useful for confirming the gestational age after timed matings and for predicting the age of animals for which the conception date is not known.

*A preliminary study of olfactory behavior of captive Lemur coronatus during the breeding season. Kappler, P. M. (Dept. of Zoology & Primate Center, Duke Univ., Durham, NC 27705). International Journal of Primatology, 1988, 9, 135-146.
. . The olfactory behavior of a captive population of crowned lemurs was studied during their annual breeding season in order to investigate its possible role in the fine-tuning of mating synchrony after photoperiodic initiation of reproductive activity.

*Twinning among Callimico goeldii. Altmann, J., Warneke, M., & Ramer, J. (Allee Lab. of Animal Behavior, Univ. of Chicago, 940 E. 57th St., Chicago, IL 60637). International Journal of Primatology, 1988, 9, 165-168.
. . One of the main features that distinguishes callimicos from callitrichids is the production of only a single infant per gestation, rather than the litter size of two that sets the Callitrichidae apart from all other anthropoid primates. This is a report on 4 sets of twins among 188 pregnancies among callimicos at Brookfield Zoo. In the one pair that survived, one infant had to be hand-raised, while only one infant in one other pair survived.

*Proximate and ultimate causes of reproductive suppression among female yellow baboons at Mikumi National Park, Tanzania. Wasser, S. K. & Starling, A. K. (Dept. of Psychology, Univ. of Washington, Seattle, WA 98195). American Journal of Primatology, 1988, 16, 97-121.
. . Attack coalitions, whereby two or more individuals attack another animal simultaneously, were studied for 14 months in 53 sexually mature female baboons from one small and two large troops. Results suggest that attack coalition behavior is a form of reproductive competition whereby females attempt to suppress the reproduction of others at predictably competitive times and thereby reduce the competition their own infants face from the time they are weaned.

*Ejaculate quality, testes size and sperm competition in primates. Møller, A. P. (Dept. of Zoology, Uppsala Univ., Box 561, S-751 22 Uppsala, Sweden). Journal of Human Evolution, 1988, 17, 479-488.
. . Literature data on 25 primate species were examined for correlations between measures of ejaculate quality and testes size and body size, respectively. Ejaculate volume and sperm concentration were positively correlated with body size in an interspecific analysis. Testes size, after controlling for the effect of body size, was related to breeding system in primates; species in which more than one male copulated with each oestrous female had larger testes than those with single-male breeding systems. Primate species with multi-male breeding systems produced ejaculates with relatively higher sperm motility and with relatively more motile sperm than did primates with single-male systems.

*Coalitions, cooperation and reproductive tactics among adult male baboons. Bercovitch, F. B. (Wisconsin Regional Primate Research Center, Univ. of Wisconsin, 1223 Capitol Court, Madison, WI 53715). Animal Behaviour, 1988, 36, 1198-1209.
. . Male savanna baboons, Papio cynocephalus, form coalitions with each other as a technique for gaining access to a female in consort with another male. Reciprocal altruism has been invoked as the primary mechanism underlying this reproductive tactic, but a 19-month field study of the reproductive behavior of olive baboons, P. c. anubis, in Kenya contradicted this interpretation. Males who solicited others for coalition formation were not more likely to gain access to consort females than were their fellow coalition members. Males who refused to participate in a coalition at one time were still sought as coalition partners at other times by the same male. Coalitions were generally formed by older, middle- to lower-ranking males and targeted at younger, higher-ranking males. Coalitions are a low risk reproductive tactic and the benefits are not partitioned according to initiator/joiner status.

*Alterations in primate sperm motility with maturation and during exposure to theophylline. Gould, K. G., Young, L. G., & Hinton, B. T. (Yerkes Regional Primate Research Center, Emory Univ., Atlanta, GA 30322). American Journal of Primatology, 1988, 15, 325-336.
. . Data show that sperm from the caput epididymis of the chimpanzee have the capacity for normal motility, but do not have the capacity to bind to and penetrate an ovum, while sperm from its cauda epididymis have the capacity for normal motility as well as the capacity to bind to and penetrate an ovum.

*Puberty in primates. Plant, T. M. (Dept. of Physiology, Univ. of Pittsburgh School of Medicine, Pittsburgh, PA 15261). In E. Knobil, J. Neill et al. (Eds.). The Physiology of Reproduction (pp. 1763-1788). New York: Raven Press, 1988.
. . The study of puberty in primates has been restricted almost exclusively to the infraorder, Catarrhini. In such higher primates, puberty may be viewed as manifesting itself as a result of the cascade of physiological and behavioral processes that are set in motion by the reawakening of a dormant, but apparently fully mature, hypothalamic GnRH pulse generator. Although physiological models with a central neural timekeeping system or growth-tracking device have been proposed to account for the timing of puberty, the mechanisms that dictate the arrest and reawakening of the hypothalamic GnRH pulse generator during postnatal life remain a fundamental problem in developmental neurobiology. Studies of New World primates and prosimians are scant, and therefore it is not presently possible to speculate whether the timing of puberty in the lower primates is subserved by the same mechanisms that govern this process in Old World monkeys, apes, and humans.

*Progesterone levels during pregnancy in the greater thick-tailed Galago (Galago crassicaudatus) . Izard, M. K. & Fail, P. A. (Duke Univ. Primate Center, Durham, NC 27705). Journal of Medical Primatology, 1988, 17, 125-133.
. . Serum progesterone concentrations in Galago crassicaudatus were measured at 3-week intervals throughout the 136-day pregnancy. Progesterone concentrations were significantly elevated over those of nonpregnant controls as early as 6 weeks after conception, and continued to increase throughout gestation. The progesterone profile in pregnant G. crassicaudatus quantitatively resembles that of chimpanzees and qualitatively resembles that of humans. In two animals that aborted, progesterone concentrations after abortion decreased to values comparable to those seen in nonpregnant animals.

*The primate oviduct and endometrium. Brenner, R. M. & Maslar, I. A. (Oregon Regional Primate Center, 505 NW 185th Ave, Beaverton, OR 97005). In E. Knobil, J. Neill et al. (Eds.), The Physiology of Reproduction (pp. 303-329). New York: Raven, 1988.
. . The cyclic fluctuations in serum estradiol and progesterone that occur during the primate menstrual cycle are clearly responsible for the dramatic, cyclic changes that occur throughout the reproductive tract. This review focuses on the similarities and differences in hormonal responsiveness that exist between the primate endometrium and oviduct.

*Infant mortality in mother-reared captive chimpanzees at Taronga Zoo, Sydney. Courtenay, J. (Dept. of Zoology, Australian National Univ., Canberra City, ACT, 2601, Australia). Zoo Biology, 1988, 7, 61-68.
. . Sex-specific mortality probabilities were calculated for mother-reared chimpanzees using standard demographic techniques with Taronga Zoo records. Male mortality was found to be considerably higher than female mortality. Changes in infant mortality over time were calculated, with particular reference to changes that had occurred since the chimpanzees were transferred to a new open air enclosure in 1980. Mortality was found to have decreased dramatically since the move to the new enclosure, but the observed decline was exaggerated by the very high proportion of female infants. The main causes of infant death were pneumonia and trauma. In addition, undetermined causes in the first day of life were numerous. An examination of the contexts of infanticide in wild and captive chimpanzees revealed slight differences, but factors such as aggression towards unfamiliar individuals and redirected aggression were common to both. Cannibalism in the zoo has so far been limited to the bodies of stillborn infants.

*Responses of foster-mothers and troop members to adopted newborns in a captive group of rhesus monkeys. Holman, S. D. & Goy, R. W. (MRC Neuroendocrine Development and Behaviour Group, AFRC Inst. of Animal Physiology, Babraham, Cambridge CB2 4AT, England). Primates, 1988, 29, 343-352.
. . Two male and two female rhesus monkeys between 24 and 120 hours old, born to females caged singly, were exchanged with same-sex infants born to females in a large troop which was held in an enclosure in a different building. Both foster-mothers and other troop members recognized the unfamiliarity and novelty of the foster infant, but the infants were still accepted into the group.

*Social correlates of reproductive suppression in captive callitrichid family groups. Carroll, J. B. (Jersey Wildlife Preservation Trust, Les Augres Manor, Trinity, Jersey, Channel Islands). Dodo, 1986, 23, 80-85.
. . Case histories from the records of the callitrichid colony at Jersey Wildlife Preservation Trust, which suggest that familial relationship between father and daughter or mother and son is important in suppression of breeding, rather than dominance relationships between mother and daughter or father and son.


*Gentle lemurs: New species, and how they are formed. Groves, C. P. (Dept. of Prehistory & Anthropology, Australian National Univ., Canberra, ACT 2601, Australia). Australian Primatology, 1988, 3[2/3], 9-12.
. . Descriptions of, and comments on, the characterization, taxonomy, evolution, and conservation, of the species and subspecies of Hapalemur.

*Systematics of the Lemuridae (Primates, Strepsirhini). Groves, C. P. & Eaglen, R. H. (Dept. of Prehistory & Anthropology, Australian National Univ., Canberra ACT 2601, Australia). Journal of Human Evolution, 1988, 17, 513-538.
. . After reviewing the literature and examining museum specimens of the family Lemuridae, the authors suggest the elevation of the fulvus group to the rank of genus, and propose the name Petterus for it, with type P. fulvus. The incorporation of Petterus in the family Lemuridae, without including any suprageneric groupings, provides a way of indicating the present uncertainty about the phylogenetic affinities among its members.

*Molecular systematics of higher primates: Genealogical relations and classification. Miyamoto, M. M., Koop, B. F., Slightom, J. L., Goodman, M., & Tennant, M. R. (Dept. of Zoology, Univ. of Florida, Gainesville, FL 32611). Proceedings of the National Academy of Science, 1988, 85, 7627-7631.
. . The authors obtained 5' and 3' flanking sequences (5.4 kilobase pairs) from the psi-eta-globin gene region of Macaca mulatta and combined them with available nucleotide data. The completed sequence, representing 10.8 kilobase pairs of contiguous noncoding DNA, was compared to the same orthologous regions available for human (Homo sapiens, as represented by 5 different alleles), common chimpanzee (Pan troglodytes), gorilla (Gorilla gorilla), and orangutan (Pongo pygmaeus). The nucleotide sequence for Macaca mulatta provided the outgroup perspective needed to evaluate better the relationships of humans and great apes. Pairwise comparisons and parsimony analysis of these orthologues clearly demonstrated that humans and great apes share a high degree of genetic similarity and that humans, chimpanzees, and gorillas form a natural monophyletic group. These conclusions strongly favor a genealogical classification for higher primates consisting of a single family (Hominidae) with two subfamilies (Homininae for Homo, Pan, and Gorilla, and Poninae for Pongo).

Taxonomic status of Saguinus tripartitus (Milne-Edwards, 1878). Thorington, R. W. Jr. (NHB 390, Smithsonian Institution, Washington, DC 20560). American Journal of Primatology, 1988, 15, 367-371.
. . A review of specimens and field notes show that Saguinus tripartitus and S. fuscicollis lagonotus are sympatric, although they probably occur in different habitats. Therefore, S. tripartitus should be treated as a distinct species, not as a subspecies of S. fuscicollis.


In many cases, the original source of references in this section has been the Current Primate References prepared by The Primate Information Center, Regional Primate Research Center SJ-50, University of Washington, Seattle, WA 98l95. Because of this excellent source of references, the present section is devoted primarily to presentation of abstracts of articles of practical or of general interest. In most cases, abstracts are those of the authors.
