Successful Application of PCR-amplified DNA Markers for Paternity Determination in Rhesus Monkeys (Macaca mulatta) and Chimpanzees (Pan troglodytes)

Prior to the establishment of the NIH Regional Primate Research Centers in 1962, pedigreed nonhuman primates were not widely available, thus limiting the possibilities of genetic research. But now availability of approximately five rhesus generations and three chimpanzee generations affords many opportunities for biomedical research where genetically-defined animals are necessary, such as studies of transgenic animal models, models for human AIDS (Desrosiers, 1990), and complex (polygenic) human diseases (MacCluer, 1993; Stone, et al., 1987). The efficient use of animal models requires accurate pedigrees. This can best be accomplished by using genetic markers capable of corroborating and ascertaining parentage. In effect, genetic markers are indispensable tools for genetic management, allowing the formulation of rational breeding plans for maintaining genetic variation, minimizing inbreeding, and providing sound research strategies even when the focus is not genetics (Ely & Ferrell, 1992; Williams-Blangero, 1993). For example, genetic markers allow evaluation of the effects of common ancestry (i.e., shared genes) on experimental outcomes, since related animals may exhibit correlated responses for any trait under genetic control (Williams-Blangero, 1993). Thus, potentially misleading results are possible unless pedigrees have first been confirmed with genetic markers. Even with fastidious husbandry and record-keeping, up to 5.5% errors are common in primate pedigrees (VandeBerg, 1992).

Until recently, the genetic markers of choice for monitoring pedigrees included biochemical polymorphisms, blood types and lymphocyte antigens (Stone et al., 1993). Although still useful, these classical markers are neither as efficient nor as convenient as the newer DNA markers (Smith et al., 1992; Stone et al., 1993). Fortunately, there are nearly 4000 human-derived short tandem repeat (STR) DNA markers commercially available which can be screened to determine their utility for genetic typing of nonhuman primates. Here we report the use of human-derived STR markers amplified by polymerase chain reaction (PCR) for solving disputed parentage cases in rhesus monkeys and chimpanzees with very high efficiency.


Rhesus samples were obtained from animals housed at the University of Texas M. D. Anderson System Cancer Center, Bastrop, TX (Bastrop); the Wisconsin RPRC, Madison, WI; and the Laboratory of Comparative Ethology, NICHD, Poolesville, MD. Chimpanzee samples were obtained from Bastrop; the Primate Foundation of Arizona, Mesa, AZ; New Iberia Research Center, New Iberia, LA; and the Coulston Foundation, Holloman AFB, NM.

Five to 10 ml of whole blood were collected into vacuum tubes containing EDTA, an anti-coagulant, and shipped to our laboratory by overnight courier. High molecular weight DNA was extracted by a salting-out method (Miller et al., 1988) and resuspended in 500-1000 micro-l of full-strength buffering solution (10 mM Tris-Cl, 0.2 mM EDTA, pH 7.5) depending on yield. These samples were used as template DNA in PCR reactions using human-derived PCR primers obtained from Research Genetics (Huntsville, AL). Primers were randomly selected from all 22 human autosomes to determine which ones amplified rhesus or chimpanzee DNA. The goal was to identify primers which amplified homologous, polymorphic loci in these nonhuman primate species. Primers which amplified were optimized for MgCl2 concentration (1.5-3.5 mM) and buffer pH (8.5-10.0) using a commercially available PCR optimization kit (Invitrogen, PCR Optimizer). Otherwise, standard PCR cocktails consisted of 50 ng of each primer (forward and reverse), 200 micro-M of dATP, dGTP, dTTP, 2.4 micro-M of dCTP and 2.5 micro-M of 33P-dCTP, 0.5 U Taq polymerase (Promega), 50 mM KCl, 10 mM Tris-Cl, pH 8.3, and 15 ug template DNA in a reaction volume of 15 micro-l. PCR was performed with an initial 5 min denaturation at 94deg.C followed by 30 cycles of 1 min/94deg. denaturation, 45 sec/55deg. annealing, and 1.5 min/72deg. extension plus 2 sec autoextend per cycle, with a final extension of 10 min at 72deg.C. PCR reactions were performed on an Ericomp TwinBlock thermal cycler in 96-well microtiter trays with a mineral oil overlay. Four microliters of PCR product were diluted 1:2 with a denaturing loading dye (formamide/EDTA/xylene cyanol/bromophenol blue), loaded into 6% denaturing polyacrylamide gels and electrophoresed for 2.5 hr at 60W. Gels were dried for 30 min on a vacuum pump, wrapped in Saran wrap, then inserted in autoradiograph cassettes with Kodak XAR-5 X-ray film and allowed to expose at room temperature (22+/- 4deg.) for 3-4 days, before developing.

Since the alleles at STR loci are codominant, allele frequencies were determined directly by gene counting. Gene diversity (equivalent to expected heterozygosity) was estimated as one minus the sum of the squared allele frequencies (Nei, 1987). Paternity exclusion probabilities were caluculated using the generalized paternity exclusion index (Chakravarti and Li , 1983).


In the process of screening 480 STR markers from human chromosomes I through X, we identified 381 primers which amplified rhesus DNA. Of these, 145 markers (38%) appeared to amplify homologous loci, as determined by similarity of the length of the amplified fragment to the known lengths of the human alleles. From these, we selected 14 STR markers for paternity testing which were polymorphic, as indicated by tests on a sample of five unrelated rhesus, and which exhibited Mendelian segregation in an 8-member, 3-generation rhesus pedigree. This battery of markers was then studied for its application to paternity testing. As shown in Table 1, each locus exhibited from 2 to 7 alleles (mean = 3.6), with gene diversity between about 20% to about 78% (mean = 58%). The estimated mean paternity exclusion probabilities for these 14 markers ranged from 0.089 to 0.737 (mean = 0.356), with a combined mean exclusion probability, PE, of 0.99999. In other words, the probability that a false sire could be correctly excluded by one or more of these 14 markers is nearly 100%.

We used these 14 STR markers in an attempt to resolve paternity cases. First we used our "progressive paternity exclusion" strategy to reduce the number of putative sires by testing several biochemical polymorphisms including the transferrins (Stone et al., 1993). After that, we ended up with 16 paternity cases involving 37 putative sires, with up to five sires per case. Thirteen of the 16 paternity cases (81%) were definitively resolved using the STR markers, by excluding all putative sires, except one, at two or more loci. We concluded that the the remaining putative sire, who was not excluded at any locus, was indeed the true sire.

Table 2: STR loci (markers) used in chimpanzee paternity determination.

We studied another set of 35 human STR markers for use in chimpanzee paternity cases. Of these, eight (23%) did not amplify. However, 27 primers (77%) amplified a chimpanzee DNA fragment in the expected size range: 19 (70%) detected polymorphic loci, while eight of these (30%) detected monomorphic loci. As shown in Table 2, 12 of these 19 polymorphic markers exhibit between two and seven alleles each (mean = 4.3), with gene diversity between about 49% and about 76% (mean = 63.5%). Locus-specific mean exclusion probabilities range from 0.184 to 0.861 (mean = 0.518), with a cumulative mean exclusion probability of 0.99998. These 12 markers were used in eight paternity cases involving a total of 23 putative sires, with up to four putative sires per case. Six of the eight paternity cases (75%) were unequivocally resolved using this battery of STR markers.


To our knowledge, this is the first report of the successful use of PCR-amplified human STR markers for routine paternity testing in nonhuman primates. Human-derived STR markers have been used in other studies involving nonhuman primates, including population history, individual identification, and phylogenetics (Bowcock et al., 1994; Deka et al., 1994; Garza et al., 1995; Morin et al., 1994; Pascall et al., 1994). The application of STRs to parentage determination in nonhuman primates has been suggested, but not previously reported, as part of routine colony maintenance and genetic management (Garza et al., 1995; Morin et al., 1993). Other researchers reported the cloning of species-specific STR markers (Takenaka et al., 1993), but this labor-intensive approach yielded a small number of markers which limited their use in other species and their application to genetic studies such as linkage.

We have demonstrated that human-derived STR markers can be applied to routine paternity testing in rhesus monkeys and chimpanzees with a high degree of success. These STR markers are much more efficient than the classical genetic markers. For example, the three most useful classical markers routinely used in our laboratory (transferrin, carbonic anhydrase II, diaphorase I) averaged 4.7 alleles per locus, but only 38% average heterozygosity. More importantly, the mean exclusion probability was 0.25559, with a cumulative exclusion probability of only 0.61030. In contrast, using our battery of 14 STR markers, we were able to attain a cumulative mean exclusion probability of 0.99999 in rhesus monkeys. Similarly, the 12 STR markers used in chimpanzees gave a cumulative mean exclusion probability of 0.99998. We anticipate that our ability to solve paternity cases will become even more powerful as we identify more polymorphic STR markers. We also expect to reduce the amount of time and cost involved in paternity testing by developing multiplexed PCR reactions by identifying three to four STR markers, easily distinguishable by their different allele sizes, to run in the same lane on a single gel.

Finally, it is important to understand why genetic tests sometimes fall short of the theoretical expectations. We typed 37 putative sires involved in 16 rhesus paternity cases with up to 14 STR markers each. Each marker defines a DNA type, or genotype, at a single locus. Among the 37 putative sires, we defined 147 genotypes which enabled us to exclude 27 putative sires and make 13 paternity determinations. On average, 5.4 (147/27) genotypes were needed per exclusion, while 11.3 (147/13) genotypes were required per case. However, the remaining three disputed parentage cases, which were refractory to resolution despite using many polymorphic markers, clearly involve animals who share more than the expected number of alleles. Many shared alleles can indicate common descent, that is, inbreeding. We are not the first to infer that a very high exclusion index sometimes translates into a smaller number of conclusive paternity determinations due to inbreeding (Smith et al., 1992). Even highly efficient DNA markers cannot compensate for lack of sound breeding practices as part of routine colony maintenance.

Travelers' Health Notes: Myiasis Warning Again

In the July, 1993 issue of the LPN, we printed a report of myiasis (the invasion of human or animal tissue by the larvae of flies) in a scientist who had been conducting research in the rain forest of Costa Rica. In the December, 1995 issue of Missouri Medicine (92[12], 764-765), K. J. Mott & P. C. Anderson report on a zoologist who returned from a field trip in a Peruvian rainforest with two Dermatobia hominis in the skin of his hand. Physicians must be aware of their patients' travel histories!

"In Central and South America, D. hominis is the most common intruder into the skin of explorers. The infestation begins insidiously after the eggs are deposited on the skin of the unaware host. The comforting warmth of the skin stimulates the eggs to hatch. The larvae then burrow into the skin to complete development before reemerging approximately 50 days later.

"Dermatologically, soon after penetration of the skin by the larva, a small 2-3 mm papule develops that is not likely to be noticed in a bug-ridden jungle. The tiny papule soon enlarges into a dome-shaped nodule, at which point the clinical appearance may resemble a furuncle, particularly when the lesion becomes pointed as the posterior end of the larva protrudes from the wound. An intermittent foul-smelling discharge, commonly mistaken for `pus', is actually sloughed larval remnants. Severe piercing pain, a reliably classic symptom of myiasis, is attributed to the tearing of the host's tissues by the oral hooks of the larva during feeding. Removal of the larva is in itself curative."

Toys for the Boys: Environmental Enrichment for Singly Housed Adult Male Macaques (Macaca fascicularis)

Cobie Brinkman
Division of Psychology and Centre for Visual Science, Australian National University


In the last ten years, ever since providing for the "psychological well-being" (PWB) of captive nonhuman primates (Animal Welfare Act, 1985) was first demanded, "environmental enrichment" has been considered an essential part of such provision. No agreed-upon definition of PWB exists because it is likely to be specific to both the species (Clarke & Mason, 1988; Thomas & Lordon, 1989) and the individual (Boccia et al., 1995); but a reasonable degree of PWB is assumed when an animal is in good health, its behavioral repertoire approaches that seen in wild populations, and abnormal behaviors are reduced or absent (Novak & Suomi, 1989). Environmental enrichment (EE) may thus be defined as any measure which promotes expression of natural, species-specific behaviors and a decrease in, if not disappearance of, abnormal behaviors.

An impressive list of EE devices, toys, and husbandry procedures can be collated from the literature (e.g., Reinhardt & Reinhardt, 1992), and several books have appeared (Novak & Petto, 1991; Segal, 1989). But there are problems. Many toys have no attraction beyond their novelty value (Fazji et al., 1989; Reinhardt & Reinhardt, 1992), and some devices such as food puzzles require a considerable investment of human labor and thus, money (Moazed & Wolff, 1988). Regarding husbandry procedures, because macaques are social animals, housing of previously singly caged macaques in pairs or in groups appears to conform to the definition of PWB, and can produce long-lasting results, especially for females or for adults paired with an infant (Reinhardt, et al., 1995). However, pairing or grouping of adult males has often proved to be difficult because of aggression (Crockett, et al., 1994), and such pairings may be easy only when animals are related, have grown up together, or when there is a considerable age difference, as in adult males and infants (Reinhardt et al., 1995). For males in particular, it may be unreasonable to assume that for every monkey in captivity, a compatible partner exists and that this partner can be found, as pointed out by Crockett (1993).

Because of increased captive breeding, more males will be available for research. Because of experimental demands, such animals may have to be housed singly but may be involved in experiments for many months. To provide for PWB for such single male macaques is a formidable challenge to animal house staff and researchers. Few papers deal with the specific problems of a small number of animals actively involved in research. This paper describes some toys, devices, and procedures which have been found to be useful (or not!) for adult male macaques housed singly for a number of years while involved in behavioral research into control of movement.

The Boys

Five male longtailed macaques (Macaca fascicularis) provided data for this paper. All were captive-born, weaned between 6 and 12 months of age, then reared in a mixed-sex peer group with visual and auditory contact with the natal group and, when 2 to 3 years old, transferred to an all-male group of juveniles. Two monkeys were half-brothers from the same natal group, the others were unrelated. All had been housed singly for short periods (2 to 3 weeks), and all but one spent up to three years as breeder males before the start of this study, at which time they were aged between 6 and 13 years and weighed 6 to 10 kg. Several times/week, they took part, for 1 to 2 hours, in different tests of motor behavior for food rewards. These experiments lasted for 2 to 3 years. Housing, cage furniture, toys and devices, and foods, the most common sources of EE (Bayne, 1991), will be presented below. All were used for periods of 1 to 3 years, and some for 4 to 5 years, until the present day. All aim at extending the "psychological space" (Chamove, 1989) of an animal with restricted physical space.

The Toys

In Australia, few laboratories use nonhuman primates. Therefore, the National Health and Medical Research Council's Policy on the Use of Non-human Primates in Medical Research (1995) is not as prescriptive as the U.S. equivalent. Expected is an environment that "meets the behavioural demands of the species", allows the animal to "display species-specific behaviours" and, preferably, "appropriate social groupings". On the other hand, contact with conspecifics must be provided when adult males require single housing because of aggression.

Housing: There is no prescribed cage size or shape, and cages are usually built locally. The males of this study were housed in cages with a floor area of 95 x 100 cm (appr. 3'1" x 3'3"), and a height of 110 cm (3'8", inside dimensions). Walls and roof were made of 1" x 2" galvanized steel mesh while vertical steel bars, 5 cms (2") apart, were used for the front, which included a 40 x 40 cm (1'4") sliding door. The floor was made of stainless steel 5 x 5 cm mesh over a removable, stainless steel sawdust tray (Figure 1). The cage was mounted on a 50 cm (1'8")-high trolley. Cages were kept in sets of 5, 4, 3, or 2, so animals could see and hear each other, in conventional animal holding rooms. Compatible animals, such as the two half-brothers, were allowed tactile contact as well, by placing the cages with the fronts facing each other. However, very little contact, such as allogrooming, was ever seen, and clear dominance rankings existed for all animals despite single housing.

Figure 1: Monkey in cage with toys.

Cage furniture: Each cage was fitted with a perch 40 cm (1'4") below the roof, made of two hardwood slats pushed through the mesh and held in place by large drop-in bolts (Figure 1). Perches were preferred for eating, resting, and sleeping. Perches that were easier to clean were made of 5 cm diameter PVC piping (orange conduit or bright yellow gas pipe), secured in the same way. Animals spent more time on perches made of two pipes, 5 cm apart, than on a single-pipe perch. Each cage also had one or two sun-dried hardwood branches (Figure 1). These were not secured. The animals would sit on them, and three of the animals liked "rearranging the furniture", handling and lifting the branches.

Table I: Toys and devices assessed for longterm use and benefit.

Toys and devices: A number of toys and devices have been tried. If possible, they had to be cheap, cleanable (cleaned toys were given back to the original owner to prevent them from acting as fomites, cf. Bayne et al., 1993), and require little extra human labor. They are listed in Table I. It can be seen that some, such as balls, mirrors and rawhide bones (Eaton et al., 1993), were of little interest to the animals; others were used by at least some monkeys for long periods. The latter include 3 cm

(1.25") plastic rings cut from 40 cm (1'4") diameter PVC pipe; large infant formula or instant coffee cans and their metal lids, which animals would use as hand-held mirrors; thick cotton horse-lead ropes clipped to the cage, which were chewed on, and which at least one animal would thread across and around perch and branches; and coconuts (Taff & Dolhinow, 1989), which were groomed bare if not broken first. Very successful toys, used extensively by all animals, were cardboard boxes or tubes and cedar wood in the shape of barbells. Pine was found to be too soft and hardwoods too hard, but cedar was slowly chewed into wood chips by the animals (which did not seem to ingest any wood, or suffer upsets if they did). Lengths of garden hose, threaded through one or more cages, were used for manipulation, climbing, and chewing (again without apparent ingestion or adverse effects). Brightly colored plastic fishing line reels were hung on hoses and ropes for more manipulation and chewing. By far the most successful enrichment was plastic two-liter milk bottles, or soft drink, juice, or syrup bottles; not rinsing the latter before giving them to the monkeys added extra flavor to the animals' experience. Bottles were either suspended from the cage front with a clip and short chain, or put inside the cage. Animals would manipulate them, throw them, chew them, and tear them into pieces. Clear (PET) bottles were preferred (apparently because they make more noise when handled) over softer, opaque bottles, and monkeys would play for days even with PET pieces. Labels were systematically "groomed" off. Sometimes monkeys were given empty shampoo bottles with caps removed but only lightly rinsed. The olfactory stimulus appeared to be of great interest because the animals carried the bottles around, sometimes for hours, before destroying them. Plastic bottles have retained their appeal for over four years now.

Food: Until recently, no primate chow was produced in Australia. Instead, animals were fed 4 to 8 ounces per day of a mix made up of commercial rat, rabbit, goat, and sheep pellets, corn kernels, and black, unshelled sunflower seeds. Because the species is "crab-eating" in the wild, cat biscuits were added. The mix was supplemented daily by a medium apple, half a banana, and some cabbage. The mix could be put into the plastic bottles, with a cut-off large funnel, or mixed into (sterilized) sawdust in the tray or a large horse feed bin hung at the front of the cage. Animals would forage for long periods in the tray, but not in the bin. Breakfast cereals or molassed horse grain mix were sometimes substituted. Other fruits and vegetables were often used. The animals have sampled just about anything grown in this country and apparently enjoyed it, with the exception of some pungent (onions, leeks) or bland (lettuce, commercial tomato and strawberries) foods. Fruits and vegetables were cut up and placed on top of the cage. The animals could retrieve them by pushing them to one of a few 5 x 5 cm holes cut into the ceiling to make it into a large "puzzle-box" (cf Reinhardt, 1993). To prevent food falling onto the floor, a 5 cm-high barrier was erected around the cage top (Figure 1). Corn kernels or sunflower seeds were sometimes given in a PVC pipe with a screw top at one end, easily made from plumbing supplies. Small holes drilled in the pipe allowed food to fall out when the tube was rolled or handled. Browse was also given: poplar or willow branches in summer, lucerne hay in winter.


Because "psychological well-being" has no clear definition, its assessment is problematical (Novak et al., 1995; Novak & Suomi, 1989; Thomas & Lordon, 1989) and, therefore, so are the effects of enrichment. The latter usually are measured as decreases in nonfunctional, abnormal behaviors, such as stereotypies, and increases in species-specific behaviors, or in time spent with environmental enrichment devices (e.g., Bryant, et al., 1988); but not all studies present quantitative data (see reviews by Fajzi et al., 1989; Reinhardt & Reinhardt, 1992). In the present study, animals were free from abnormal behaviors as they changed from social to single housing, unlike the rhesus studied by Goosen (1989), possibly because they had been in single cages several times before and, therefore, did not experience the change as stressful. Avoidance of stress, should single housing be necessary, either for experimental or medical reasons, was, in fact, the aim of having periods of single housing as part of a captive-born monkey's standard "education". Also, from the start, animals were provided with EE and involved in the experimental training program, which in itself can be enriching (Laule, 1993). After two to three years, no abnormal behaviors had developed (Chamove, 1993, James, 1993) and the animals were judged to behave in a manner appropriate to their species, age, and sex (James, 1993). No formal quantitative data are available, but because of the long periods of time during which the same animals have been kept in single housing, and during which these cheap toys, devices, and procedures have been tried and retried, others faced with the problems of singly housed social animals may find this qualitative evaluation of use. No other studies have reported on EE exposure for such long periods (Reinhardt & Reinhardt, 1992). It should also be noted that the animals used here are longtailed macaques. This species appears to be more susceptible to stress than the rhesus monkey (Clarke & Mason, 1988). The use of this species is increasing and its EE needs, as compared to those of rhesus monkeys, should be further explored.

Although cage size is not strongly correlated with well-being when assessed over short periods (Crockett et al., 1993; Crockett and Bowden, 1994; Line et al., 1991), when animals are kept in them for a number of years it may become important. The size of the cages used here allowed the animals both walking and climbing space, and they could sit on the perch without their tails touching the ground (Figure 1). The cage has almost twice the floor area and is 50% higher than the U.S. equivalent for animals this size (USDA, 1991). It is larger than the European standard range, and close to that of the UK (Poole & Hubrecht, 1994). While this size may still not be adequate, it has kept the animals in good physical condition. When transferred to their present quarters, where space is increased four to eight times, the motor weakness and incoordination seen by others (O'Neill, 1989), when conventionally singly caged animals were given access to a large exercise area, were absent.

An inspection of Table I reveals that successful toys are ones that can be manipulated and carried around. Shape also matters (Mench, 1994): monkeys all but ignored plastic balls (cf Line and Morgan, 1991) but did not tire of a variety of plastic bottles. All used wooden barbells intensively. This contrasts with the variable use by rhesus monkeys of wooden sticks or branches (Champoux et al., 1987; Line & Morgan, 1991), and virtual ignoring of wooden blocks by longtailed macaques (Brinkman, unpublished observations). The importance of texture is reflected in a preference for cardboard boxes or tubes over phone books, and the interest shown in coconuts (cf. Taff & Dolhinow, 1989) compared to simple balls. Use of colored piping, hose, rope, and reels may provide a more pleasing surround for trichromatic nonhuman and human primates. The interest shown in fragrant bottles indicates that olfaction, hitherto largely neglected as enrichment, warrants further attention. Auditory stimulation is almost equally neglected. The monkeys appeared to ignore a radio (cf. O'Neill, 1989), except when attendants switched stations; but when a radio can be controlled by the animals, it is more effective (Line et al., 1991). In the present study, monkeys seemed to use cans and PVC food tubes to create noises by rolling them against the mesh or dropping them repeatedly.

Common to all toys which never lost appeal (hoses, cardboard tubes, bottles, wooden barbells) was that animals could chew and tear them. Such chewing could be a form of stereotypy which cannot be indulged in conventional single caging (except for bar-biting, a behavioral abnormality seen in some domestic animals; see Broom & Johnson, 1993, p.77). However, such behavior was never seen in these monkeys during previous periods of single-caging, and animals did not resort to it in association with stressful events, e.g., when changing cages, when visitors were present, or during other procedures known to be stressful (Crockett et al., 1993; Line et al.,1991). Rather, the oral exploring, chewing, and tearing may represent behaviors normally associated with foraging and food collection in the wild: free-ranging macaque populations are notoriously destructive. In zoos, their environment soon becomes bare unless specially protected (Coe, 1989). The opportunity to chew and tear has also benefitted the animals' dental health: no animal has required any cleaning of its teeth in the past few years.

Offering different kinds of food provides motor, sensory, olfactory and gustatory variety. Often, foods and fruits from gardens (and bottles of all kinds) have been brought in by attendants and other researchers. Their increased awareness and appreciation of the monkeys' behavioral needs, generated by the enrichment program, has been one of the most valuable outcomes, since the animals continue to benefit (Petto, et al., 1992).

Use of Two Food Foraging Devices by Singly Housed Baboons

Since the advent of USDA regulations requiring research facilities to provide environmental enrichment as a means for promoting psychological well-being in nonhuman primates, numerous strategies for providing for psychological well-being have been proposed by the primate community (Bayne, 1991). In laboratory settings where experimental protocols require individual housing, one prevalent enrichment strategy has been to provide "enrichment devices" to promote psychological well-being (e.g., Fajzi et al., 1989). Little scientific data exists, however, to support the usefulness of these devices in increasing well-being in nonhuman primates, particularly for those housed singly (Bloomsmith et al., 1991).

A large variety of enrichment devices are available for use with nonhuman primates, including feeding devices to promote foraging-type behaviors (e.g., Bloom & Cook, 1989). Engaging in feeding behaviors accounts for most of a nonhuman primate's daily activity in the wild (O'Neill et al., 1989). In captivity, feeding devices appear to engage non-human primates for longer periods of time than non-food devices. Further, studies have shown a reduction in aberrant behaviors in rhesus monkeys (Bayne et al., 1991) and chimpanzees (Maki et al., 1989) when food devices are present. One could conclude that such feeding devices do indeed promote well-being, since engaging in species-typical behaviors such as grooming and foraging are thought to indicate an increase in well-being (Novak and Suomi, 1991). The purpose of the present study was to determine the effects of two foraging devices, P-nut Butter Rolls® and Prima-Foraging Grooming Boards®, on the behavior of singly caged baboons in an experimental laboratory setting.


Subjects: Six adult male baboons (Papio anubis and P. cynocephalus), weighing 21 to 32 kg, were individually housed in the same colony room in regulation Group 4 primate cages equipped with a seating bench and free access to water. All baboons were maintained on a 12-hr light/dark cycle (lights on/off at 6 a.m./ 6 p.m.). All baboons could see and hear each other at all times. During the course of this study, all baboons participated in daily behavioral signal detection experiments. Food intake was controlled at 200 g/day. About 90% of this amount was obtained during daily 100-min experimental sessions. Baboons performed a signal detection task in which each correct detection of an acoustic signal was rewarded with a 500-mg Bio-Servreg. pellet. The remaining food was given at the end of day in the form of Purina monkey chow, along with two pieces of fresh fruit. A physical health examination was conducted once a month. All animals received a tuberculin test by the veterinary staff every three months. Animal care was in accordance with current NIH guidelines concerning the humane treatment of nonhuman primates.

Apparatus: A P-Nut Butter Rollreg. (Bio-Environmental Modifiers, Frankfort, Kansas) and a Prima-Foraging Grooming Boardreg. with Fleece Padsreg. (Bio-Serv, Frenchtown, New Jersey) served as the enrichment devices. The P-Nut Butter Roll was a device with two concentric tubes. The innermost tube was free-moving about its axis and was typically coated with creamy peanut butter (approximately 1/4 cup); the outer tube revolved around the inner tube, and had six 2 in. long x 3/4 in. wide slots for accessing the peanut butter. The Prima-Foraging Grooming Board was a dual-plated autoclavable stainless steel device. A fleece pad (90% polyester, 10% acrylic) covered the board and the board was then attached to a bracing frame. The fleece pad was coated with a small drizzling of dark corn syrup and 1 cup of mixed flavors of Prima-Foraging Crumbles (Bio-Serv, Frenchtown, New Jersey) were pressed onto the pad.

To monitor the movements of these foraging devices, wireless activity monitors were attached to each device. Each activity monitor was a 5.5 x 3.3 x 1.5 cm (LWH) unit enclosed in a plastic case (Personal Activity Monitor, manufactured by Individual Monitoring Systems, Baltimore MD). Details of the monitor's use with nonhuman primates have been described previously (Hienz et al., 1992). The monitor's internal microprocessor records "activity counts" whenever the device undergoes any accelerative movement. A monitor is sensitive to accelerations exceeding 1 m/s/s. Each activity count indicates an above-threshold acceleration within a .22-sec interval. In the present study, these activity counts were summed over 15-min intervals (i.e., summed over 4096 consecutive .22-sec bins). An activity monitor was attached to the inside of the internal tube of each P-Nut Butter Roll, or was bolted to the back of each grooming board. Each foraging device was suspended on the outside of the cage by a chain so that touching the device caused the entire device to move. Both devices were accessible through the front of a cage, but could not be pulled into a cage. Activity monitors were removed every two weeks to retrieve the data.

To record the general movements of baboons, activity monitors were placed inside protective metal cases and the cases then mounted on soft leather neck collars (3/4-in wide) that were custom-fitted to each baboon's neck. Each animal could move the case freely along the collar. The collars are well-tolerated by baboons, and do not interfere with eating or restrict body movements (Hienz et al., 1992). Each animal wore a monitor for a minimum 2-week baseline period prior to introduction of the foraging devices.

General Procedures: Three weeks prior to the start of the experiment, all enrichment devices were removed from the cages, and human interactions were recorded. Technicians entered the room under the following conditions: 1) to perform daily maintenance (e.g., to clean pans, etc.); 2) to transfer an animal from its home cage to an experimental chamber for daily behavioral sessions; 3) to mount enrichment devices on cages; and 4) to deliver afternoon supplemental feedings (4:30 pm). During testing, all food devices were removed from the baboons' cages prior to daily behavioral sessions, and were subsequently loaded with food and placed back on all animals' cages every weekday at 3:15 pm, five minutes prior to the onset of video taping sessions. Because baboons did not perform in behavioral sessions on weekends, the devices were loaded and attached at varied times between 6:00 am and 1:00 pm on weekend days. All animals were exposed to the enrichment devices over a six-week period. For the first two weeks of testing, one of the two enrichment devices was placed in a baboon's cage; the device was then removed for two weeks, followed by presentation of the other device for the next two weeks. The order of presentation of the two foraging devices is shown in Table 1. Because feeding schedules differed on weekends, only weekday data were employed for the present analyses.

Data Collection/Analysis: Videotapes were collected via three closed-circuit video cameras (Panasonic, WV-1410 CCTV cameras) mounted to the ceiling and connected to a videotape recorder programmed for automatic taping. Each camera was oriented towards a different pair of baboons, and an automated switch box randomly selected which pair was videotaped at the following times: 3:20-3:40 pm, 3:45-4:05 pm, and 4:10-4:30 pm, Monday through Friday. Each pair of baboons was videotaped during one of these times each day. Samples of each baboon's behaviors thus were obtained soon after receiving a device. Behavioral scoring of the videotapes was performed with an Event Scoring System (Princeton Economics, Inc., Princeton, MA) using the behavioral categories presented in Table 2.

Table 2: Behavioral categories used for scoring video tapes.

Videotapes of all baboons were scored during both device-absent and device-present testing phases. Samples of the use of each foraging device were taken from a minimum of three video segments representing intervals A) immediately after device presentation during the first week, B) one hour after device presentation during the first week, and C) immediately after device presentation during the second week. Comparing data from segments A and B allowed an assessment of any changes in device use over the initial exposure period, while comparison of segments A and C allowed assessment of changes over the 2-week period. One observer scored all video segments. Reliability was assessed by having a second observer score 20% of the segments; reliability was greater than 80% for all segments scored by both observers.


The recorded movements of the foraging devices are displayed in Figure 1, which shows 24-hr movement patterns for grooming boards (left column) and P-Nut Butter Rolls (right column) for each baboon. A peak in device activity occurred immediately after each device was presented (3 pm), with this peak decreasing within the next two hours. Occasional device movements were recorded overnight. Movements of the foraging devices resumed in the morning after the lights came on. Frequently, animals continued to interact with the devices on the following morning even though no food was observed on the devices at this time. In general, the same patterns of movement occurred for both devices. Paired t-tests of total daily activity across the two-week period showed that five of six baboons moved the P-Nut Butter Rolls more than the grooming boards (p < .01). This finding may be due to increased difficulty in retrieving food from the P-Nut Butter Roll, which would create more movement, or it may simply demonstrate a food preference. Analyses of the videotapes revealed that the most common ways in which the baboons interacted with a grooming board were for them to either brace the board with one hand and groom the fleece with the other, or press the board to the cage with both hands and lick the fleece. For the P-Nut Butter Roll, baboons typically braced the cylinder to the cage in some manner (e.g., pressing the cylinder to the cage), and then extracted peanut butter by either digging at the slot with one finger, or shoving all the fingers of one hand into the slot and then licking the fingers.

Figure 1: Average 24-hour patterns of movement for grooming boards (left column) and P-Nut Butter Rolls (right column) recorded from each baboon. Plotted are the number of minutes of movement of each device per 15-min interval over a 24-hr period, averaged across the two-week device exposure period (excluding weekend data). Lights-off times are indicated by the shaded areas.

Figure 2 shows the total minutes of device movements per day recorded from the grooming board (left) and the P-Nut Butter Roll (right) for each animal, plotted across consecutive weekdays. Variations occurred in how much the devices were moved across the two-week exposure periods. In some instances, the devices were moved most frequently during the first 1-3 days of exposure to the devices (i.e., grooming boards for baboons AC, CA, and WE; P-Nut Butter Rolls for baboons AC, BE, and DR), suggesting a "novelty" effect following initial exposure to the devices. Some baboons showed a gradual decrease, or habituation, in their interactions with the devices, as indicated by decreasing device movements over days (i.e., grooming boards for baboons AC, CA, and WE; P-Nut Butter Rolls for baboons AC, DR, and FR). In still other instances, some baboons moved the devices at about the same rate over the two-week period (grooming boards for baboons BE, DR, and FR; P-Nut Butter Rolls for baboons BE, CA, and WE). Finally, in two instances baboons interacted very little with the grooming board (baboons DR and FR). These differing movement patterns over time indicate that a range of individual differences exists among nonhuman primates in their interaction with foraging devices.

Figure 2: Total minutes of device movements per day for grooming boards (left) and P-Nut Butter Rolls (right) for each baboon, plotted across consecutive weekdays.

Table 3 shows the percentage of time that each baboon engaged in the six behavioral categories of Table 2 prior to being exposed to either of the two foraging devices. In general, most baboons engaged in general movements and/or rested. Baboons AC and WE, however, showed a relatively high percentage of stereotypic behaviors during this baseline period. Baboon AC repeatedly circled, braced, and sat on his bench, while baboon WE circled his cage repeatedly.

Table 3: Percentage of time occupied by behaviors during the baseline video segment.

To determine whether or not foraging device use was correlated with these six behavioral categories, the percentage of time that baboons engaged in device use was plotted as a function of the percentage of time they engaged in each of these six behavioral categories prior to exposure to either foraging device. Of the six categories, stereotypy and self-directed behaviors were highly correlated with subsequent foraging device use. Figure 3 shows plots for P-Nut Butter Roll use (left) and grooming board use (right) as a function of the percentage of time that baboons had previously engaged in stereotypical behaviors. Baboons with greater amounts of prior stereotypical behavior also interacted with the foraging devices more. The correlation between stereotypic behavior and P-Nut Butter Roll use was extremely high (r = .951, p <. 005), whereas the correlation between stereotypic behavior and grooming board use was lower (r = .626, 0.2 > p > 0.1). Further, no animal exhibited stereotypic behaviors during the videotaping times when foraging devices were attached to the cages. Figure 4 shows P-Nut Butter Roll use (left) and grooming board use (right) as a function of the percentage of time that baboons engaged in self-directed behaviors. Baboons displaying lower amounts of self-directed behaviors interacted with the foraging devices less frequently. The correlation between self-directed behaviors and P-Nut Butter Roll use approached significance (r = .793, 0.1 > p > 0.05); the correlation between self-directed behaviors and grooming board use was lower (r = .616, 0.2 > p > 0.1). The remaining behavioral categories showed no significant correlations with foraging device use.

Figure 3: The percentage of time baboons engaged in using the P-Nut Butter Roll (left) and grooming board (right), plotted as a function of the percentage of time baboons engaged in stereotypical behaviors prior to introduction of the foraging devices. A linear correlation function and the corresponding Pearson's r value are shown.

Figure 4: The percentage of time that baboons were engaged in using the P-Nut Butter Roll (left) and grooming board (right), plotted as a function of the percentage of time baboons engaged in self-directed behaviors prior to introduction of the foraging devices. A linear correlation function and the corresponding Pearson's r value are shown.

Average food pellet intakes were also examined during baseline and testing periods to determine whether exposure to the foraging devices influenced the animals' performances in the signal detection task. No differences in overall pellet intake were found between the foraging device and non-device periods (p = .64), and daily plots of each animal's signal detection thresholds showed no systematic deviations from baseline performance levels.


Our results show that singly caged adult male baboons readily interact with food-based foraging devices, and that stereotypical behaviors are reduced when the devices are present. In addition, the foraging devices elicited species-typical behaviors such as foraging and grooming, even after food appeared to be absent from the devices. These results indicate that food-based enrichment devices can have substantial benefits for singly caged baboons (e.g., reducing stereotypic behaviors). Similar results of reductions in abnormal behaviors following the introduction of feeding devices have been reported for rhesus monkeys (Bayne et al., 1991), chimpanzees (Maki et al., 1989), and cynomologus monkeys (Lam et al., 1991).

A finding of great potential significance is the correlation between foraging device use and the frequency of prior stereotypic and self-directed behaviors. In the present study, foraging devices were used more frequently by those baboons exhibiting relatively higher frequencies of stereotypic behaviors; conversely, the devices were used less frequently by baboons exhibiting relatively higher frequencies of self-directed behaviors (e.g., self-groom-ing). These correlations suggest the importance of noting the nature of abnormal behaviors in nonhuman primates before prescribing enrichment strategies for treating such problems. For example, feeding devices might be particularly helpful for animals exhibiting stereotypic "pacing" behaviors, but less so for animals exhibiting self-directed behaviors such as hair-pulling. Clearly, additional research using other nonhuman primate species is needed to determine the generality of this finding.

Previous investigators have reported that nonhuman primates show no habituation to food-related devices (e.g., Boccia, 1989). In the present study, however, the use of activity monitors allowed for a more accurate assessment of the pattern of device use over time, with the resulting data showing that some habituation occurred in two baboons (see Figure 2). Such decreases in device use could be due to animals developing more efficient methods in removing food from the devices. On the other hand, baboons also interacted with the devices in the morning after the food had been removed, suggesting that the devices may have remained beneficial even when food was not available. This "residual" interaction with an empty foraging device would contribute additional movements to the total daily device movement times of Figure 2, which may be why more habituation to the foraging devices was not observed when total movement over 24-hrs was measured.

Both the P-Nut Butter Roll and grooming board proved compatible with ongoing research protocols in that the devices were easily incorporated into technicians' daily routines. Further, although the food retrieved from the devices slightly decreased daily pellet intakes, it did not appear to adversely affect the accuracy of the baboons' performances in their behavioral tasks. Evaluating other devices in this way will assist research facilities not only in providing environmental enrichment to meet USDA regulations, but also in providing enrichment that will be most beneficial to their nonhuman primates. Although an individualized approach to enrichment may not be convenient in some research settings, this approach may alleviate some aberrant behaviors and thus increase psychological well-being in singly caged nonhuman primates.

Primates in Art and Illustration

An exhibit titled "Primates in Art and Illustration" will be held in conjunction with the IPS/ASP Joint Meeting in Madison, WI, August 11-16, hosted by the Wisconsin RPRC. The committee for the exhibit welcomes suggestions for artists to contact as well as submissions from primatologists.

Exhibit dates will be August 9-30. In addition to primatologists attending the meeting, we anticipate considerable interest in this exhibit from people in Madison and the surrounding area.

Painters, illustrators, sculptors and photographers are invited to submit samples of their work related to nonhuman primates. Works which are anthropomorphic in nature are discouraged. We anticipate being able to mount approximately 50-55 works in two galleries, with each artist being represented by not more than 3-5 items. Works will be juried by a panel of primatologists and local area artists. Unless specially arranged, all works will be for sale with the gallery taking a 20% commission, plus an additional 10% designated for the IPS/ASP Conservation Fund. Not only is the Conservation Fund important, but people will be more likely to purchase items if they know that part of the purchase goes toward preservation of endangered primates.

Only works related to nonhuman primates will be considered. Please send 3-5 slides or photographs of your work to: IPS/ASP Art Exhibit, c/o Larry Jacobsen, Wisconsin RPRC, Univ. of Wisconsin, 1220 Capitol Ct, Madison, WI 53715-1299 [for further information, phone 1-608-263-3512; fax 1-608-263-4031; or e-mail:].

Resources Wanted and Available

Telemetry for Multiple Subjects

Prof. Dr. H. Rothe reports that a data-collecting system for simultaneous collecting of heart rates and behavioral data of up to eight small laboratory mammals has been developed by Dipl. Biol. Jens Kerl of the University of Göttingen. The data-logging program stores heart rate data together with the corresponding behavioral data for each animal. During a preliminary study on a pair of common marmosets (Callithrix jacchus), the system proved to be a powerful tool.

Primate Vocalizations

The Wisconsin RPRC Library makes a concerted effort to collect, catalog, and make accessible a wide range of recorded primate vocalizations. Without an effort to conserve this material, which may ultimately be the only audiovisual documentation for some endangered primates, these important vocalizations may be lost. "Whether you have one call or a full repertoire available, we would like to hear about your work. If you have audiotaped vocalizations you could contribute, we would like the best quality copies available. If you cannot part with the original recording, we accept copies which we may retain. We also have the facility to make copies. This process usually takes 2 weeks, after which the original is returned to the contributor. If you are planning any future research which may involve taping vocalizations, please keep us in mind. Any help in pointing us toward potential sources of material would also be appreciated." For further information, contact Ray Hamel, Special Collections Librarian, Wisconsin RPRC, 1223 Capitol Ct, Madison, WI 53715.

Announcements From Publications

Journal of Medical Primatology

Munksgard Press has announced that "Due to problems between the New York University Medical Center and LEMSIP (Laboratory for Experimental Medicine and Surgery in Primates) the publication of Journal of Medical Primatology has been delayed and, subsequently, Dr. Jan Moor-Jankowski has asked us as publishers to be released as Editor-in-Chief."

Professor Jorg W. Eichberg of the Biomedical Primate Research Centre in Rijswijk, the Netherlands, will be the new Editor-in-Chief. The journal will be published bimonthly, i.e. a total of six issues including the special issue from the Annual Primate Centre Meeting. "Professor Eichberg is currently assembling a new Editorial Board and will announce the Board, including a new aim and scope, in the first 1996 issue of Journal of Medical Primatology." As a consequence of the delay, only four of the eight 1995 issues will be published.

African Primates

African Primates is in need of articles for issue no. 3 which is due to come out in mid-1996. Articles in French are particularly desired. African Primates publishes information relevant to the conservation of nonhuman primates and their ecosystems in Africa. Please refer to issue no. 1 for answers to your questions or contact Tom Butynski, Zoo Atlanta, P.O. Box 24434, Nairobi, Kenya [fax: 254-2-890615; e-mail:]. It is hoped that this newsletter will enhance the conservation of African primates: by increasing interest in their survival, by alerting people to situations where primate species and populations are under threat, and by providing a forum for useful debate on some of the more pressing, controversial, and sensitive issues that have an impact on the conservation of these primates.

The success of this newsletter depends largely upon the willingness of those people involved with primate conservation in Africa to provide relevant information on research findings, field survey results, advances in field and laboratory techniques, field action alerts, book reviews, events, job announcements, funding possibilities and recent publications. African Primates also announces letter-writing campaigns and other activities which might benefit from the support of its readership.

Award Nominations

ASP Conservation Awards and Grants

Nominations for Conservation Awards and Grants are now being sought by the American Society of Primatologists (ASP). These awards and grants, funded from the ASP Conservation Fund, are a contribution to the larger conservation picture and a mechanism to recognize deserving colleagues and students, including those from primate habitat countries -- countries with native primate fauna -- for whom the prestige of an ASP award or grant can be a valuable aid to the recipient's conservation efforts. An award nomination is basically a letter of recommendation. A grant proposal should consist of a few narrative pages plus a budget page.

The Subscription Award provides the American Journal of Primatology to worthy individuals in habitat countries who otherwise would have little access to the scientific literature on nonhuman primates. The Society expects to support several such continuing awards. Preference is given to those who will make the journal available in a central place for colleagues to use, and to those who can justify brief reapplication every two years to build up their library of the journal. A nominating letter should describe the nominee's credentials and his/her primate-related activities, and explain why the nominee deserves to receive high priority.

The Conservation Award ($500) provides recognition and financial support for students and young investigators from habitat countries who demonstrate potential for making significant and continuing contributions to primate conservation. Those eligible include students, young investigators, and educators in countries with native nonhuman primates and for whom no more than five years have elapsed since receipt of the terminal degree. Nominators should provide the nominee's name, title and full mailing address and a statement about the nominee's qualifications for the award, focusing on past and potential contributions to primate conservation. Supporting letters from other individuals acquainted with the work of the nominee may be submitted. Past awards have been presented by U.S. Ambassadors or other senior officials, thereby obtaining favorable publicity for the award, its recipient, and primate conservation in the recipient's country.

Senior Biology and Conservation Award ($500 Honorarium) is one of ASP's highest honors. It is given to recognize an individual without an advanced degree who has made substantial contributions over many years to promote primate conservation either through direct action or via enhancement of biological knowledge or well-being of primates. Such contributions could arise from work done in field, laboratory or zoo settings. Nominees might work directly with primates or be engaged in activities supporting those who work with primates. Examples include park rangers, census takers, animal caretakers, research technicians, assistants or facilitators, and individuals involved in private enterprise benefitting primate conservation. Nominating letters should detail the nominee's qualifications, contributions to primate conservation, period of service, and full mailing address. Supporting letters from other individuals acquainted with the work of the nominee may be submitted. This award typically is presented at public ceremonies by senior officials.

Conservation Small Grants (up to $1,500 but usually $500) are given for conservation research or other projects, including conservation education. ASP and IPS members working in habitat countries are especially urged to apply or to help someone from a habitat country submit a meaningful project, which can be a portion of a larger effort. Grant proposals must be typed in English, should not exceed 2000 words, and should include a brief budget page. Recipients of grants must agree that a brief progress report, in a form suitable for publication in the ASP Bulletin, will be made within 12 months of the award.

Evaluation and Application Procedure: With the exception of requests for emergency support, which can be considered at any time for immediate action, the Conservation Committee will make its recommendations for awards and grants to the ASP Executive Committee at its annual meeting. Successful nominees and applicants will be informed following the meeting and their names published in the ASP Bulletin. The 1996 deadline for submission of nominations and grant proposals is June 30. They should be sent to Ramon J. Rhine, Psychology Dept, University of California, Riverside, CA 92521.

W. W. Howells Prize

The W. W. Howells Prize is awarded by the Biological Anthropology Section of the American Anthropological Association to honor a book in the area of biological anthropology. The book should inform a wider audience of the significance of physical/biological anthropology in the social and biological sciences and demonstrate a biocultural perspective. Nominated works should represent the highest standards of scholarship and readability. The book may have multiple authors, but may not be an edited volume. Books must be published within the last three to four years and once nominated will remain on the list for three to five years, depending on their date of publication.

Previous winners of the Prize are: 1993: Dorothy Cheney and Robert Seyfarth (1990) How Monkeys See the World: Inside the Mind of Another Species. University of Chicago Press. 1994: Matt Cartmill (1993) A View to a Death in the Morning: Hunting and Nature through History. Harvard University Press. 1996 (awarded in 1995): William C. McGrew (1992) Chimpanzee Material Culture. Cambridge University Press.

Nominations, in the form of a letter and accompanying material, such as book reviews, should be sent to: Karen Rosenberg, Department of Anthropology, University of Delaware, Newark, DE 19716 [302-831-1855; fax: 302-831-4002; e-mail:].

Internet Connection for Medical Institutions

The National Library of Medicine (NLM) is encouraging the development of a communications infrastructure to promote the rapid interchange of medical information nationally and throughout the world. This infrastructure is based upon the Internet, a network of networks that was developed with the support of the National Science Foundation. Internet access provides health professionals engaged in education, research, clinical care, and administration with a means of accessing remote databases, libraries, NLM's Grateful Med, DOCLINE, and Loansome Doc; of transferring files and images; and of interacting with colleagues throughout the world. To accelerate the pace with which health-related institutions become part of the electronic information web, NLM is offering grants to support Internet connections.

Support is available for development and enhancement of multi-institution networks including extending connectivity to outlying sites, or otherwise furthering NLM's goal of expanding information outreach. Institutions will usually be expected to fund the local area network and support other costs of the gateway system. Grant funds may be used to expand access to the Internet in an institution with an existing connection.

Prospective applicants are asked to submit a letter of intent by April 17, 1996. The application receipt date is May 16, 1996. Direct inquiries to Ms. Frances E. Johnson, Div. of Extramural Programs, NLM, Bldg 38A, Rm 5S-520, Bethesda, MD 20894 [301-496-4221; fax: 301-402-0421; e-mail:].

L. S. B. Leakey Foundation Grants

The L. S. B. Leakey Foundation was formed to further research into human origins, behavior, and survival. Recent priorities have included research into the environments, archaeology, and human paleontology of the Miocene, Pliocene, and Pleistocene; into the behavior, morphology, and ecology of the great apes and other primate species; and into the behavioral ecology of contemporary hunter-gatherers. Other areas of study related to human evolution have been funded occasionally.

Advanced pre-doctoral students, as well as established scientists, are eligible for General Research Grants, normally given to the exploratory phases of promising new projects that most closely meet the stated purpose of the Foundation. A special Fellowship for Great Ape Research promotes long-term research on the behavior and ecology of wild populations of great apes, especially if, in addition to the basic scientific goals of the project, the work contributes to the development or testing of models of human evolution. Both continuing and new projects wlll be considered. Strong preference is given to post-doctoral applicants prepared to make a long-term commitment to the study site. The Paleoanthropology Award is intended for potentially long-term, multidisciplinary research programs which seek to recover the physical and/or cultural remains of early humans and their hominid ancestors. Franklin Mosher Baldwin Memorial Fellowships are awarded to Africans who seek to complete an advanced degree in anthropology at a major institution and is limited to a two-year program of advanced training towards an M.A., Ph.D., or equivalent. Priority is given to students of disciplines related to human evolution.

Wildlife Research Expedition, Peru

The Dallas Zoological Society and the Detroit Zoological Institute announce their Third Wildlife Research Expedition to Peru to study and census rare primates of the Peruvian Amazon, June 5-19, 1996. A group of volunteers will work with experienced zoo personnel, local assistants, and Peruvian students to map the travels of seven species of primates (squirrel, woolly, titi, and two species of capuchin monkeys, sakis, and red uakaris), noting population densities and spacing.

This will not be the usual travel experience. In fact, it is an adventure only for the physically hardy. The primate expedition entails regular eight-hour treks through the forest, swamps, and hills of the rain forest. Occasionally, balancing acts over fallen timber that span streams or gullies may be necessary, as well as clambering over fallen logs, under branches, and around thorny bushes. Always a wary eye is kept for the local herpetofauna. Days on the primate study begin around 6 am and conclude sometime after 8 pm with dinner, discussions, and clean-up.

Living conditions are comfortable but primitive. Participants will sleep in large 3-person tents (or you may bring your own single-person tent), bathe in the stream, and utilize pit toilets. So, pack your sense of humor first and prepare to be amazed by the power of nature in a wonderland where the birds bark like dogs and the primates (and dogs) sing like birds.

Cost of the trip is $2,100, excluding airfare. Some of the trip expenses are tax deductible. For more information please contact: Cynthia Bennett, Research Curator, or Wanda Weaver, Dallas Zoo, 621 East Clarendon Dr.,

Dallas, TX 75203 [214-670-6833; e-mail: or]; or Scott Carter, Mammal Curator, Detroit Zool. Inst., P.O. Box 39, Royal Oak, MI 48068-0039 [810-398-0903].

Program In Primate Behavior

This summer Florida State University, Panama Canal Branch, will offer an intensive training program in the scientific study of primate behavior. The program, June 16 to July 26, 1996, will be held on the 33-hectare island of Isla Tigre in Gatun Lake. Eight tamarins (Saguinus geoffroyi) have recently been released on the island. These tamarins allow the close approach of observers and are individually identified by bead collars. These will be the primary focus of behavioral and ecological research conducted during the class.

Students taking the program will take concurrent courses in Primate Behavior, Ecology, and Research Topics in Psychology and will therefore earn 9 semester hours of credit for the successful completion of the program. This is an intensive program designed for students who have a serious interest in the study of primate behavior and ecology. The cost with round trip air fare from Florida will be $2,708, while the cost for students from Panama will be $2,237.

News Briefs

Univ. of Washington Press Release

Officials at the University of Washington's Primate Field Station at Medical Lake, WA, responded to the death of a 5-month-old macaque monkey last November by notifying the U.S. Department of Agriculture's Animal and Plant Health Inspection Service, dismissing the employee responsible for the incident, and taking steps to prevent a recurrence.

As part of a regular site inspection, USDA inspectors on Dec. 7 confirmed that the macaque had died from apparent water deprivation. The water supply to the room where the animal was housed had been turned off over a weekend.

A post-mortem examination by field station personnel showed that the animal had been ill and possibly dehydrated before being deprived of water. The USDA report stated that the death would likely not have occurred if the animal had not had a prior medical problem, since no other animal in the room died.

The employee responsible for the room was dismissed from employment for failing to check the automatic watering device and for entering a false report that indicated the device had been checked.

The facility has taken appropriate steps to prevent a recurrence of this type of incident. -- University of Washington Press Release, January 5, 1996

Gorilla Birth at Los Angeles Zoo

A gorilla was born at the Los Angeles Zoo on 17 January, 1996. The infant, a female, was born to Angel, an 8-year-old female, and Tzambo, a 23-year-old male. This was Angel's first pregnancy; she was born at the zoo and reared in her natal group. Tzambo is wild-caught, and has sired only one other offspring. The infant was full term; weight at birth was 5 lbs. 10 1/2 oz., gestation was 257 days.

Unfortunately, the infant was found abandoned on the floor, unmoving, and her body temperature was below 74 degrees. After the infant was warmed and stabilized, we attempted to re-introduce her, but the mother showed no interest in her. She is being hand-reared in the zoo's nursery. She is strong and appears to be thriving at this writing, and we hope to attempt an early introduction to her natal group.

In L.A. we have made every attempt to allow females to rear their infants since we stopped routinely pulling all gorillas at birth in 1987. That year, we had three infants born, all reared by their mothers. Of these three mothers, two were hand-reared with no prior offspring and no experience with infants, and one was a mother who had had several infants pulled. Our philosophy is to leave infants with the mother unless leaving it obviously risks the infant's life, as was the case here. Interestingly, this mother was mother-reared in a stable group with another infant 4 months older than she was. In other words, she had everything going for her. -- From reports on Primate-Talk by Jennifer J. Chatfield, Gorilla Keeper, Los Angeles Zoo

Life and Death at Woodland Park Zoo

Woodland Park Zoo announced the birth of Jumoke and Congo's first western lowland gorilla baby. The five-and-a-half-pound female was born Monday, February 12, at 11:23 pm PST. Jumoke and Congo's infant marked the seventh successful gorilla birth at Woodland Park Zoo.

Congo was born in Cameroon around 1959. On breeding loan from the Honolulu Zoo, Congo came to Woodland Park from Phoenix Zoo in 1992. His transfer to Woodland Park provided his first-ever experience with a grassy, naturalistic habitat. Congo had never successfully mated with his two previous mates, Fifi and Hazel, at Honolulu and Phoenix, respectively.

Just two weeks after his daughter's birth, on February 27, Congo suffered a seizure and died suddenly while being examined by the animal health staff. Gorilla keepers noticed on the 25th that Congo was lethargic. He showed very little interest in eating or drinking and behaved as if he was suffering from some non-specific pain. Zoo animal health staff initially diagnosed Congo to be afflicted with Balantidium, causing diarrhea and excessive gas. He was treated with an antibiotic and ibuprofen for pain. The keepers were offering fluids and treats to encourage him to eat at 10:00 am on the 27th, when he suffered a seizure. The animal health staff immobilized Congo to further examine him and assess his condition but, while they were examining him, he stopped breathing and died in spite of resuscitation attempts.

The preliminary postmortem indicated no obvious cause of death. Complications related to age (average life expectancy for a captive gorilla is 40 years) and a very severe systemic infection, possibly associated with abscessed teeth, were apparent. A fractured upper left canine and an upper right second molar were found to be abscessed (he had had prior dental problems resulting in root canals and fillings). Also found was a systemic infection causing infarcts, including 50% loss of left kidney and small portions of the liver. There was also hemorrhage in the lungs, possibly as a result of resuscitation attempts, and some lesions in the heart. The actual cause of death will not be known until a histology review.

Congo epitomized the true "gentle giant" spirit of his species and was a wonderful animal to work with and to be around. The zoo's staff is devastated by this loss. We hope to to attempt an early introduction to her natal group. -- Laurence Gledhill, Woodland Park Zoo, on Primate-Talk

Chimpanzee with AIDS Euthanized

The first animal to develop the clinical disease of Acquired Immune Deficiency Syndrome (AIDS) as a result of infection with the human immunodeficiency virus (HIV-1) was euthanized February 13. The animal, a 15-year-old Yerkes Primate Research Center chimpanzee named Jerom, was humanely euthanized because medical tests, including one conducted that morning, indicated that his anemia was becoming more severe and untreatable. Anemia, which also occurs in people with AIDS, results from the failure of the bone marrow to produce adequate numbers of oxygen-carrying red blood cells.

"There was no evidence that Jerom was in pain before his death," said Thomas R. Insel, M.D., director of the Yerkes Center, which is part of Emory University. "But, it was clear to the veterinarians, the researchers and myself that Jerom had reached terminal stages of the disease and was beyond the point of recovery. We wanted to prevent further deterioration of his clinical condition. There was little likelihood that additional information would be gained by prolonging his life."

With Jerom's death, the number of Yerkes chimpanzees involved in AIDS research totals 12. Thus far, none of these animals, all of which live in pairs for social companionship, shows signs of AIDS. They will remain the core of the AIDS research efforts with chimpanzees, since there are no immediate plans to infect additional chimpanzees.

"Whether you're working with human patients or with nonhuman animals, AIDS research continues to raise ethical issues within the scientific and medical communities and within the public at large," Dr. Insel pointed out. "Studying and caring for the first animal with AIDS has been challenging. We have treated opportunistic infections aggressively but ultimately we were left fighting a relentless disease for which there still is no cure."

Jerom was one of 13 chimpanzees at Yerkes who were inoculated with HIV-1 as part of a research study conducted with the U.S. Centers for Disease Control and Prevention in Atlanta, to develop a primate model for research, including vaccine studies. The project was initiated over 10 years ago. Like most of the animals at Yerkes, the 13 chimpanzees were captive-born for research purposes.

Although Jerom became persistently infected with HIV -- his immune system produced antibodies against the virus, and virus was isolated repeatedly from samples of his blood -- from the time he was infected over a decade ago, clinical signs of AIDS did not occur until late summer of 1995.

Although he did not receive anti-viral drugs, Yerkes veterinarians treated Jerom for clinical disease that occurred secondarily to the HIV infection. In addition to receiving extensive care from Yerkes veterinarians, Jerom also was the focus of a great deal of personal attention from the center's primate caretakers and the center's behavioral scientist who is in charge of enrichment of the laboratory animals' environment.

Yerkes researchers and animal care experts also have been paying close attention to Nathan, one of the 12 remaining chimpanzees. He received an experimental blood transfusion from Jerom in September 1995. Nathan's CD4+ cells have dramatically declined but he has not yet developed clinical AIDS. That the virus affected Nathan's immune system more quickly than Jerom's was not a surprise, explained Dr. Harold McClure, who heads the Yerkes AIDS research studies, since scientists know that "passage" of an infectious agent from one animal to another can alter the virus and increase its pathogenicity.

The development of clinical AIDS in Jerom was reported by Yerkes scientist Dr. Frank Novembre at a scientific conference last fall, and on Jan. 30 at the Conference on Retroviruses and Opportunistic Infections in Washington, D.C.

Yerkes scientists have initiated studies to determine whether the HIV isolate from the chimpanzee with AIDS can infect and induce disease in pigtailed macaque monkeys. "The availability of a more readily available, less expensive monkey model for HIV-1 infection would be an extremely important animal model system for studies of the pathogenesis of HIV-1-induced disease as well as for the evaluation of AIDS drugs and vaccines," said Dr. McClure, Associate Director for Research Resources at Yerkes. -- From a February 13 press release by the Yerkes Primate Research Center, Emory University

Anatomy & Physiology

Correlation of CSF 5-HIAA concentration with sociality and the timing of emigration in free-ranging primates. Mehlman, P. T., Higley, J. D., Faucher, I., Lilly, A. A., Taub, D. M., Vickers, J., Suomi, S. J., & Linnoila, M. (LABS, P.O. Box 557, Yemassee, SC 29945). American Journal of Psychiatry, 1995, 152, 907-913.
. . In adolescent male rhesus macaques living in naturalistic settings, CSF 5-HIAA concentration is positively correlated with affiliative sociality. Animals with low CSF 5-HIAA concentrations exhibit less social competence and emigrate from their social groups at a younger age than those with higher concentrations.

Social effects and circadian rhythms in squirrel monkey pituitary-adrenal activity. Lyons, D. M., Ha, C. M. G., & Levine, S. (Dept of Psychiatry & Behav. Sci., Stanford Univ. School of Med., Stanford, CA 94305). Hormones and Behavior, 1995, 29, 177-190.
. . Observations and measurements suggest that squirrel monkeys housed without companions hypersecrete cortisol at a morning peak because adrenal responsiveness to ACTH is enhanced. Low circulating ACTH levels in turn are maintained by robust glucocorticoid feedback mechanisms that inhibit the synthesis or release of pituitary ACTH.

Primate rod and cone photoreceptors may differ in glucose accessibility. Nihira, M., Anderson, K., Gorin, F. A., & Burns, M. S. (M. S. B., Dept of Ophthalmology, UC Davis School of Med., 1603 Alhambra Blvd, Sacramento, CA 95816). Investigative Ophthalmology & Visual Science, 1995, 36, 1259-1270.
. . Brain glycogen phosphorylase immunoreactivity was found in cone, but not rod, photoreceptors in the eyes of adult humans and monkeys. Rod and cone photoreceptors have the biochemical capability to transport exogenous glucose from the circulation. Cones could be more resistant to acute reductions in circulating glucose during hypoglycemia. However, during hypoxic insult, glycogen-olysis and anaerobic glycolysis could result in increased production of intracellular lactic acid, potentially predisposing the cone to acidotic damage.

Recombinant human megakaryocyte growth and development factor stimulates thrombocytopoiesis in normal nonhuman primates. Farese, A. M., Hunt, P., Boone, T., & MacVittie, T. J. (Exp. Hematology, Armed Forces Radiology Research Inst., 8901 Wisconsin Ave, Bethesda, MD 20889-5603). Blood, 1995, 86, 54-59.
. . Recombinant human megakaryocyte growth and development factor (r-HuMGDF) was administered subcutaneously to normal, male rhesus monkeys once a day for 10 consecutive days at 2.5, 25, or 250 micro-g/kg of body weight. Results suggest that the single protein MGDF is a major physiological regulator of thrombocytopoiesis.

Hematological and serum biochemical values in pregnant and postpartum females of the squirrel monkey (Saimiri sciureus). Suzuki, T., Suzuki, N., Shimoda, K., & Nagasawa, H. (Inst. of Ozaki Lab., Hamri Co, Ltd., 2638-2 Ozaki, Sanwamachi, Sashima-gun, Ibaraki 306-01, Japan). Experimental Animals, 1996, 45, 39-43.
. . Values from 18 animals, from 12 weeks before to 12 weeks after normal births, plus control values from nonpregnant females.

Regional distribution and characterization of nitric oxide synthase activity in the brain of the common marmoset. Gerlach, M., Oehler, D., Blum-Degen, D., Lange, K. W., Mayer, B., Reichmann, H., & Riederer, P. (Univ.-Nervenklinik, Abt. Klin. Neurochem., Julius-Maximilians-Univ., Füchsleinstr. 15, D-97080 Würzburg, Germany). NeuroReport, 1995, 6, 1141-1145.
. . The brain of the common marmoset shows no hemispheric asymmetry of specific NOS activity.

Animal Models

The pathogenicity of behavior and its neuroendocrine mediation: An example from coronary artery disease. Manuck, S. B., Marsland, A. L., Kaplan, J. R., & Williams, J. K. (Behavioral Physiology Lab., 506 Old Engineering Hall, 4015 O'Hara St, Univ. of Pittsburgh, Pittsburgh, PA 15260). Psychosomatic Medicine, 1995, 57, 275-283.
. . In cynomolgus monkeys several psychosocial variables, e.g., social instability and behavioral dominance and subordination, promote coronary atherogenesis, either independently or in interaction. Animals exhibiting a heightened cardiac responsivity to stress also develop the most extensive coronary lesions. Social stress causes injury to arterial endothelium and, among chronically stressed animals, impairs endothelium-dependent vasomotor responses of the coronary arteries.

Chemotherapy-induced hemolytic uremic syndrome: Description of a potential animal model. Hillyer, C. D., Duncan, A., Ledford, M., Barrett, T. J., Klumpp, S. A., Anderson, D. C., McClure, H. M., & Winton, E. F. (Emory Univ. Hospital Blood Bank, 1364 Clifton Rd, NE, Atlanta, GA 30322). Journal of Medical Primatology, 1995, 24, 68-73.
. . Data from four rhesus monkeys that developed fatal hemolytic uremic syndrome after high-dose chemotherapy indicate that these animals may model this syndrome in oncology and bone marrow transplant patients.

Tumor necrosis factor-alpha in serum of macaques during SIVmac251 acute infection. Clayette, P., Le Grand, R., Noack, O., Vaslin, B., Le Naour, R., Benveniste, O., Théodoro, F., Frétier, P., & Dormont, D. (Lab. Neuropath. exp. de Neurovirologie, CEA/DSV/DPTE/SSA, 60-68 ave. Division Leclerc, B.P.6, 92265 Fontenay aux Roses, Cédex, France). Journal of Medical Primatology, 1995, 24, 94-100.
. . SIVmac251-infected cynomolgus macaques could be a model to explore the interdigitation existing between HIV and tumor necrosis factor in acute and chronic infection, and to develop new therapeutic strategies.

Zidovudine treatment prolongs survival and decreases virus load in the central nervous system of rhesus macaques infected perinatally with simian immunodeficiency virus. Rausch, D. M., Heyes, M. P., Murray, E. A., & Eiden, L. E. (Sect. on Molecular Neurosci., Lab. of Cell Biology, NIMH, Bldg 36, Rm 3A17, Bethesda, MD 20892). Journal of Infectious Diseases, 1995, 172, 59-69.
. . Two of 5 infected, untreated monkeys developed motor impairment within 6 months following infection; motor impairments did not occur in infected, zidovudine-treated monkeys until after the drug was discontinued.

Reactivation of human immunodeficiency virus type 2 in macaques after simian immunodeficiency virus SIVmac superinfection. Petry, H., Dittmer, U., Stahl-Hennig, C., Coulibaly, C., Makoschey, B., Fuchs, D., Wachter, H., Tolle, T., Morys-Wortmann, C., Kaup, F.-J., Jurkiewicz, E., Lüke, W., & Hunsmann, G. (Dept of Virology & Immunology, DPZ, Kellnerweg 4, D-37077 Göttingen, Germany). Journal of Virology, 1995, 69, 1564-1574.
. . The presence of an apathogenic viral variant seems to retard the disease occurring after infection with a pathogenic virus, rather than to confirm total protection. This partial protection appears to depend on a specific proliferative T-cell response early after infection.

Early intrathecal events in rhesus macaques (Macaca mulatta) infected with pathogenic or nonpathogenic molecular clones of simian immunodeficiency virus. Smith, M. O., Heyes, M. P., & Lackner, A. A. (Dept of Clinical Sci., College of Vet. Med. & Biomed. Sci., Colorado State Univ., Fort Collins, CO 80523). Laboratory Investigation, 1995, 72, 547-558.
. . Findings support the following hypotheses of early events in SIV neuropathogenesis: (a) Pathogenic virus invades the CNS within days of i.v. inoculation and elicits an intrathecal immune response, including intrathecal synthesis of IgG and macrophage activation; (b) the immune response initially is associated with a decreased virus load in the CNS; (c) as immunodeficiency develops, virus load in the CNS increases once again; and (d) both virus and host factors are important in determining the course of events.

Distribution of SIV in lymph nodes of serially sacrificed rhesus monkeys. Baskin, G. B., Martin, L. N., Murphey-Corb, M., Hu, F.-S., Kuebler, D., & Davison, B. (Dept of Pathology, Tulane RPRC, 18703 Three Rivers Rd, Covington, LA 70433). AIDS Research and Human Retroviruses, 1995, 11, 273-285.
. . One male and one female with high levels of antigenemia and one each with a lower level were sacrificed at 2, 4, 8, and 24 weeks after inoculation with SIVDeltaB670. Results showed that disease course is determined within 2 weeks after experimental inoculation with uncloned pathogenic SIV, and that viral RNA is widespread in the lymph nodes of animals with rapidly or slowly progressing disease.

Progression to AIDS in macaques is associated with changes in the replication, tropism, and cytopathic properties of the simian immunodeficiency virus variant population. Rudensey, L. M., Kimata, J. T., Benveniste, R. E., & Overbaugh, J. (J. O., Dept of Microbiology, SC-42, Univ. of Washington, Seattle, WA 98195). Virology, 1995, 207, 528-542.
. . This study demonstrates important similarities in the phenotypic viral changes that accompany development of AIDS in SIV and HIV-1 infections.

Seroepizootiology of Helicobacter pylori gastric infection in nonhuman primates housed in social environments. DuBois, A., Fiala, N., Weichbrod, R. H., Ward, G. S., Nix, M., Mehlman, P. T., Taub, D. M., Perez-Perez, G. I., & Blaser, M. J. (Dept of Med., Uniformed Services Univ., 4301 Jones Bridge Rd, Bethesda, MD 20814-4799). Journal of Clinical Microbiology, 1995, 33, 1492-1495.
. . Plasma collected over a year from 196 rhesus monkeys housed in indoor gang cages, outdoor corrals, or free-ranging forest demonstrate that these animals may serve as a model for human infection.

Effects of Helicobacter pylori infection on gastric mucosal defense factors in Japanese monkeys. Fujiyama, K., Fujioka, T., Murakami, K., & Nasu, M. (Second Dept of Internal Med., Oita Med. Univ., Hasama-machi, Oita, 879-55 Japan). Journal of Gastroenterology, 1995, 30, 441-446.

Long-tailed macaques avoid conflicts during short-term crowding. Aureli, F., van Panthaleon van Eck, C. J., & Veenema, H. C. (Yerkes RPRC, Emory Univ., Atlanta, GA 30322). Aggressive Behavior, 1995, 21, 113-122.
. . Data from 42 individual M. fascicularis in different age-sex classes showed that only mild forms of aggression increased under short-term crowded conditions. Crowding resulted in a decrease in counteraggression, allogrooming, playing, and exploring, along with an increase in huddling with companions. The animals reduce the risk of severe aggression when interindividual distances are small by simply decreasing the level of activity. When aggression does occur during crowding, tension reduction mechanisms such as reconciliation and redirection are used as often as in control conditions.

Temperament in nonhuman primates. Clarke, A. S. & Boinski, S. (Harlow Primate Lab., Univ. of Wisconsin, 22 N. Charter St, Madison, WI 53711). American Journal of Primatology, 1995, 37, 103-125.
. . Studies of temperament in nonhuman primates have provided a useful framework for characterizing consistent variations among primates in behavioral and physiological responsivity at both the individual and species levels. The temperamental dimension that has been most useful is that of bold/shy or fearful/unfearful in response to novelty. Characteristics desplayed by individuals appear to have a constitutional basis, yet are to some extent modifiable by experience. Tentative evidence suggests that bold primate species may utilize more active and instrumental foraging strategies than less bold species.

Exploratory behavior and learning in laboratory marmosets (Callithrix jacchus jacchus): Comparisons between experimental-cage and home-cage activity. Forster, F. C. (Dept of Psychology, Lancaster Univ., Lancaster LA1 4YF, England). Primates, 1995, 36, 501-514.
. . In an isolated experimental cage, marmosets which learned a lever-pressing task showed higher general activity levels than controls; in the group home cages, the mere addition of novel objects resulted in enhancement of exploratory behavior. Although the activities associated with learning tended to decline over time, the novel objects remained interesting throughout the experiment.

Are daughters more costly to produce for Japanese macaque mothers? Sex of the offspring and subsequent interbirth intervals. Takahata, Y., Koyama, N., Huffman, M. A., Norikoshi, K., & Suzuki, H. (Naruto Univ. of Education, Naruto, Tokushima 772, Japan). Primates, 1995, 36, 571-574.
. . A tendency for longer interbirth intervals following the birth of daughters than of sons was seen in a sample of 237 live births recorded over 30 years.

Behavioral changes across the menstrual cycle in isosexual groups of bonnet macaques (Macaca radiata). Bassoff, T. B. (20 Plaza St [F1], Brooklyn, NY 11238-4929). Primates, 1995, 36, 549-562.
. . Behavioral changes were recorded over a six-month period for two lab-housed triads of bonnet macaques. An increase in contact aggressive hehaviors during the early-mid follicular phase and the mid-late luteal phase does not suggest a simple hormonal correlate, as these two phases are characterized by high levels of estrogen and progesterone, respectively. However, the distribution of nonaggressive hierarchical behaviors suggest that this category of agonistic interaction may be related to mating competition.

Effects of chronic melengestrol acetate contraceptive treatment on perineal tumescence, body weight, and sociosexual behavior of hamadryas baboons (Papio hamadryas). Portugal, M. M. & Asa, C. S. (C. S. A., St. Louis Zoo, Forest Park, St. Louis, MO 63110). Zoo Biology, 1995, 14, 251-259.
. . Treatment with melengestrol acetate can be recommended based on its ability to suppress ovarian cyclicity without causing social disruption. However, because this and other progestins stimulate weight gain, their use is contraindicated in overweight or obese animals.


Successful survival of primates receiving transplantation with "dead," nonbeating donor hearts. Gundry, S. R., Fukushima, N., Eke, C. C., Hill, A. C., Zuppan, C., & Bailey, L. L. (Div. of Cardiothoracic Surgery, Dept of Surgery, Loma Linda Univ. Med. Center, 11234 Anderson St, Loma Linda, CA 92354). Journal of Thoracic and Cardiovascular Surgery, 1995, 109, 1097-1102.
. . Baboon hearts recovered 15 to 31 minutes after cardiac standstill caused by anoxia can be transplanted, reperfused, and reanimated without difficulty with the use of clinically applicable methods. The use of donors with nonbeating hearts could be extended to human cardiac transplantation, greatly expanding the donor pool.

Secondary organ allografting after a primary "bridging" xenotransplant. Ye, Y., Luo, Y., Kobayashi, T., Tani-guchi, S., Li, S., Niekrasz, M., Kosanke, S., Baker, J., Mieles, L., Smith, D., & Cooper, D. K. C. (Oklahoma Transplantation Inst., Baptist Med. Center, 3300 NW Expressway, Oklahoma City, OK 73112). Transplantation, 1995, 60, 19-22.
. . In four baboons that had undergone previous xenotransplants, subsequent organ allografting was not followed by hyperacute, antibody-mediated, or accelerated cellular rejection. Organ xenotransplantation using discordant or concordant donor species does not prohibit subsequent allotransplantation.

Red cell compatibility testing in baboon xenotransplantation. Triulzi, D. J. & Jochum, E. E. (Dept of Pathology, Univ. of Pittsburgh Med. Center, 3636 Blvd Allies, Pittsburgh, PA 15213). Transfusion, 1995, 35, 756-759.
. . Description of a simple technique to determine the ABO group in baboons, to aid in the selection of baboon donors for hepatic xenotransplantation.

Heteroagglutinins and their significance in baboon hepatic xenotransplantation. Triulzi, D. J., Jochum, E. A., Marino, I. R., & Starzl, T. E. (Address same as above). Transplantation, 1995, 60, 127-131.
. . Based on data from two human patients who received baboon livers, human antibaboon heteroagglutinins do not appear to be associated with hyperacute or cellular rejection, but their role in the complement-mediated injury, suspected in both cases, cannot definitively be excluded.

Virus infection of baboons. Plagemann, P. G. W. (Dept of Microbiology, Univ. of Minnesota, Minneapolis, MN 55455). Nature, 1995, 377, 98.
. . Simian hemmorrhagic fever, which is endemic in some populations of Papio anubis and P. cyanocephalus, could be transferred to humans by xenotransplantation.
