The Behavioral Profile and Environmental Enrichment of a Squirrel Monkey Colony

A major factor hindering the definition of simple, effective guidelines for optimizing primate well-being is the fact that the environmental needs of primates differ across species: husbandry techniques that promote the well-being of one species will not necessarily transfer to another species (NIH, 1991). The most powerful perspective from which to devise environmental enrichment devices for a specific primate taxon in captivity, and subsequently to evaluate their implementation, is a detailed knowledge of that species' natural history (Fragaszy & Adams-Curtis, 1991; Redshaw & Mallinson, 1991).

Quite recently, several long-term field studies have documented the typical behavior and daily activities of wild squirrel monkey (Saimiri sciureus) populations (e.g., Janson & Boinski, 1992). In this report we present a preliminary comparison of the behavioral profiles of wild squirrel monkeys and those in a typical, well-maintained research colony. We also document the effects of a variety of simple enrichment techniques which were selected to exploit the specialized foraging behavior of squirrel monkeys. We particularly sought to identify enrichment techniques that would be effective, yet easy and inexpensive to employ.

Our findings indicated an unexpectedly high level of atypical behavior in a husbandry regime typical for squirrel monkeys used in research. The enrichment techniques we examined ameliorated, but did not eradicate, undesirable behavior.


Study animals. The subjects were 16 squirrel monkeys (Saimiri sciureus), one female and the remainder male (no significant sex difference was identified in the data). Judging from the pelage, they appeared to be hybrids from several subspecies (Costello et al., 1993). All the subjects had been intermittently used in the same general research protocol (testing reinforcement schedules) for varying periods (1 to > 5 years). The animal husbandry protocols and caging employed in this colony were approved by the Institutional Animal Care and Use Committee (IACUC) at the University of Florida, and the colony has been regularly inspected and approved by the USDA.

The monkeys were housed in two cage racks (each with eight single-animal cages in two stacked rows of four) facing each other across a space approximately 3 m wide in a windowless animal room (approximately 4 x 4 x 3 m). Cages were 17.5 x 24 x 26.5" and equipped with a perch and water bottle, with a litter pan beneath containing wood shavings that the subjects could reach. The sides of a cage adjacent to another cage were solid sheet metal, and the remaining walls of a cage were thick wire mesh. Thus a monkey had constant visual contact with the eight monkeys in the opposite rack, but no regular visual contact with monkeys occupying the same rack. The light-dark schedule in the room was 12:12. Each subject was fitted with a collar that attached to the outside of its cage via a one m long thin metal chain.

The monkeys were provided with monkey chow daily and constant access to water. Fruit was given several times a week. On an irregular basis the monkeys had one or two small plastic toys (mirrors and chains) suspended in their cage and were given "treats" such as meal worms and sweet breakfast cereal.

Data collection. All behavioral observations took place from 1400-1700 hr on weekday afternoons from 14 September to 13 November 1992. The first two weeks of observation were used to establish mutual reliability among the five observers. The control (baseline) behavior of the 16 squirrel monkeys was determined in the next two weeks. During this baseline period all enrichment devices and protocols were excluded from the cages. In each of the subsequent weeks of observation a single enrichment device was introduced into each cage. In the final week of the study, the subjects were split into two groups, each of which received a different device (PVC or jug).

Focal interval sampling (Fragaszy et al., 1992) was employed. This interval sampling technique gives reliable estimates of the relative allocation of time to different behavior categories, but not the duration of each behavioral bout.

For each observation session, an observer's initial focal subject was randomly selected. That subject was observed for a five-minute observation trial with scan samples at 30-second intervals. The observer employed a check sheet for each trial and marked the behavior categories observed at the beginning of each of the 10 intervals. Subsequent focal subjects were selected in a predetermined sequence dependent on the initial focal subject, until all had been observed. Two such series of all subjects usually were completed in each observation session. For each subject for each condition there was a minimum of four and a maximum of eight observation trials. Data were deleted for some individuals for some conditions because of an unforeseen mishap.

The behavior catalog (see Table 1) was designed to obtain detailed information on passive vs active behavior states, especially those activities that might demand mental alertness or challenging physical coordination, or possibly indicate abnormal or stereotypic behavior patterns. Several categories also addressed the distribution of the squirrel monkeys' use of the cage volume. These categories were not mutually exclusive. For example, a subject could simultaneously use the perch and ingest food, or vertically cling to the front of the cage and manipulate its leash while scratching. Total inactive includes Huddle, Vertical cling , and Stationary rest , while Total manipulate includes manipulation of enrichment devices, leash, and genitals. Idiosyncratic behavior includes behavior such as head rolling, face rubbing, shivering, and scratching, that are potentially abnormal if exhibited at high frequencies, while Stereotypic behavior refers to abnormal, repetitive motor patterns, such as pacing, swaying, or running in horizontal or vertical loops.

Enrichment Devices. The enrichment devices used were selected because they are inexpensive and simple to prepare, clean, maintain, and replace. They also had to be small and lightweight, and not require complex manipulations or the application of great force to function. Five environmental enrichment techniques were evaluated: crumbs, ball, tiny bottle, PVC tube , and jug .

Crumbs represented an enhancement of a common foraging situation in the cages; a monkey searching through the cage litter for pieces of food that fall through the mesh bottom of the cage. One cup of finely crushed monkey chow was scattered in each subject's litter immediately prior to the start of behavioral observations. A single bouncy, durable plastic ball about 1" in diameter was placed in each cage for the entire week in the second experimental condition. The balls were identical in shape and material, differing only in color. Tiny bottle was an empty plastic vitamin bottle (about 1.5" x 3"). PVC tube was a hollow plastic tube about 5" x 1" with screw-on end caps. About 10 small holes about .25" in diameter had been drilled in the walls of each tube. The tube was filled with litter mixed with approximately 2 oz. of peanuts and raisins. Jug was an empty two-liter plastic beverage container containing one cup of a litter-nut-dried fruit mixture. The tiny bottle, PVC tube, and jug were each placed inside each subject's cage prior to the initiation of observation each day and removed at the end of that day's observation session. When a device containing food and litter was being evaluated (jug and PVC tube), observations continued even after a subject's device had been emptied.

Data Analysis. The objective of the statistical analyses was to determine if the mean percent of time each behavior was exhibited significantly differed between each experimental condition and the control condition. Multiple trials were pooled for each subject within each condition. In other words, the mean percent of samples that each behavior category was observed for each subject within each experimental condition was determined. Two-tailed paired t-tests were used to evaluate significant differences between the control and experimental conditions.

It should be noted that the multiplicity of paired t-tests (5 experimental conditions x 17 behavior categories = 85 tests) inflated the possibility of significant results. At a significance level of P < 0.05 at least 5%, or about 4 paired t-tests, would be expected to achieve a significant level due to random variation.


Tables 1a and b show the mean percent (and standard deviation) of samples allocated to each of the 17 behavior categories during the control and five experimental conditions. The categories are arranged in sequence according to time spent in the baseline (control) condition. Comparisons in which the mean percent of a behavior in the experimental condition significantly differed from the control condition are indicated by asterisks (* P > 0.05; ** P > 0.01; *** P > 0.001).

Table 1b : Mean (SD) percent of samples in each behavior category for tiny bottle, PVC tube, and jug conditions.

Standard deviations from the group means for the control and experimental conditions were large, often exceeding the mean value. Only seven subjects ever engaged in genital manipulation, and eight subjects accounted for all instances of mouthing of body parts. Three of the 16 animals never handled any of the environmental enrichment devices placed in their cages.


Comparison with wild squirrel monkeys (c.f. Boinski, 1988). Wild squirrel monkeys are insectivorous and frugivorous. Typically, they spend 45-65% of their time travelling and searching for insects, 11% feeding, and 6-10% of their time resting. During daily activities in the wild a squirrel monkey manually and visually investigates potential foraging sites, makes foraging decisions, monitors the activity of other troop members, and searches for potential predators at a near-frenetic pace. Squirrel monkeys do not rely on strength or complex manipulative skills when foraging.

The most obvious difference between wild squirrel monkeys and those in the colony was that the former exhibited little behavior that could be considered stereotypic (e.g. pacing) or idiosyncratic (e.g. head rolling, mouthing body parts, or manipulating genitals). Juvenile and young adult male squirrel monkeys in Costa Rica did manipulate and mouth their own genitals during the brief breeding season, but at a very low incidence, less than 0.10% of time samples.

Wild squirrel monkeys engaged in locomotion in more than 25% of samples and manually searched for food on and within foliage during another 25% of samples, making 50% spent on activities comparable to "total movement," which engaged the captive study subjects for 12.5% of samples. Total manipulation among wild squirrel monkeys, as reflected by manual foraging, was seven times more common than in the captive subjects. Scanning out of cage, although relatively common in captivity at 11.4% of samples, was half as frequent as visual searching for food and anti-predator vigilance combined in the wild (24%). Huddling occurred in only a mean of 5% of behavior samples in the wild, but was six times more frequent in the study subjects. Only in regard to total inactive behavior was the difference between the two groups relatively small. Wild squirrel monkeys exhibited a lying, sitting standing, huddling, or otherwise stationary posture during 70% of samples compared to the captive subjects' 80%.

Evaluation of enrichment. The pattern of group responses varied across the five experimental conditions, but were generally beneficial (see Table 1). Total manipulation increased 20% (mostly due to a 21.4% increase in manipulation of the enrichment device) and idiosyncratic behavior was reduced 6.8% on average when a PVC tube was in a cage. Jug increased total manipulation a dramatic 32.1%, and reduced the use of the perch by 20.0% and ingest food 10.4%. Ball also had desirable effects; total idiosyncratic behavior (-3.0%) and ingesting food (-11.2%) decreased and total manipulation (8.2%) and manipulation of the enrichment device (7.0%) increased.

More moderate or mixed effects were documented during the other conditions. Tiny bottle significantly increased total manipulation (6.6%) and manipulation of the enrichment device (6.7%), and reduced total idiosyncratic behavior (-2.0%) and ingesting food (-11.8%). In addition, huddling decreased by a large amount (-20.9%), but this positive response was counterbalanced by several undesirable behavioral shifts: stationary/resting increased 17.3% and total movement decreased (-9.6%). Although huddling decreased (-9.1%) during crumbs , total idiosyncratic behavior increased (2.6%).

A tentative conclusion is that placing in the cage just about any device (within reason) that is sufficiently small or lightweight to be manipulated safely by a squirrel monkey would contribute to environmental enrichment. However, two of the most successful items, PVC tube and jug , were the two that dispensed food. Every device that was placed in the cages, except jug , also decreased idiosyncratic or stereotypic behaviors. Only crumbs , probably the easiest and cheapest technique examined, increased an undesirable (idiosyncratic) behavior. But even crumbs had a beneficial effect, reducing huddling.

Recommendations for colony management. Our results certainly argue for the presence and regular use of enrichment devices, especially those that dispense food, in the cages of singly-housed squirrel monkeys. Given the wide range of devices that proved at least moderately successful, we infer that there is much flexibility as to what devices can be employed. The major constraint would be that any potential enrichment device be of sufficiently small weight and size that it could be handled by a squirrel monkey. Devices designed to be gnawed or manipulated in a complex or strength-requiring manner would probably not be of direct benefit, except perhaps for the variety and novelty they could contribute to the cage environment. A preferred food might be more effective than, and just as easy to use as, chow crumbs, and should be tested as forage.

We did not test for any interaction effects from using multiple techniques or devices simultaneously. However, we suspect that this would be a profitable tactic to explore. This study also did not directly address the effect of a variety of enrichment devices being sequentially placed in the cages as has been shown effective with other primates (Anderson & Chamove, 1984); Poole, 1991). Yet because the duration of each experimental condition was relatively short (one week), our positive results may, in part, be ascribed to either a lack of sufficient time to become habituated to the devices, or the frequent rate at which the devices changed.

Paternity Resolution Using Simple Protein Polymorphisms in Chimpanzees

Sarah Williams-Blangero, Andrey Perelygin, Kathleen Brasky, and Paul Samollow

Southwest Foundation for Biomedical Research


Genetic management is an important component of the overall management of chimpanzee colonies. The basis for all genetic management decisions is the pedigree structure of a colony which defines genealogical relationships between all animals that have ever resided in the colony. The maintenance of basic record information on all colony animals as outlined by Dyke (1993) allows rapid construction of colony pedigrees using specialized software [e.g., PEDSYS (Dyke, 1989)]. Genetic management decisions may be focused on conservation concerns with maintaining the long-term viability of a colony (conservation-oriented genetic management) or on research concerns with maximizing the value of the colony for given research programs (research-oriented genetic management). A fully defined pedigree structure allows colony managers to avoid inbreeding, maintain genetic variability, select experimental samples of unrelated individuals, and initiate genetic analyses of experimentally relevant quantitative trait data, thereby optimizing opportunities for both conservation-oriented and research-oriented genetic management (Williams-Blangero, 1993).

A pedigree is constructed from information on maternity and paternity for each animal in a colony. Founders derived from outside sources will have unknown parentage, but maternity and paternity for animals born in the colony can be defined. In chimpanzee colonies, maternity is generally known unambiguously. The need for extensive genetic testing to resolve paternity in these colonies depends upon the breeding scheme used. When multiple adult males are housed with female breeders, then routine paternity testing may be an important component of colony management since pedigrees cannot be well defined in the absence of this information (Ely & Ferrell, 1990).

Many institutions that maintain chimpanzees rely on a single-male multi-female breeding group arrangement. In these situations, parentage testing is not a frequent requirement since maternity is known and there is only one potential sire. Occasional errors in paternity assignment will occur due to transfers of males between cages with fertile females, between-cage mating, and record-keeping errors, suggesting that pedigree verification may be useful (VandeBerg, 1992). However, such cases will generally be rare; genetic management practices should not be focused solely on routine parentage testing for all infants and their parents.

Implementation of a research-oriented genetic management program (Williams-Blangero, 1993) results in a wide range of available information with which to evaluate genetic variability in a colony. At the Southwest Foundation for Biomedical Research we have developed a panel of 18 polymorphic gene loci that will ultimately be used for research on the genetic determinants of normal physiological variation and for research-oriented genetic management of the chimpanzee colony. The availability of a common set of markers for all colony animals will allow routine pedigree verification, and permit resolution of paternity cases as they arise. This paper presents analyses of two paternity cases that arose in the SFBR chimpanzee breeding colony during 1994.

Materials and Methods

Two questionable paternity cases, each involving two potential sires, were identified by colony management staff and referred for genetic testing. One of the potential sires was common to both cases. For each case, blood samples were obtained from the offspring, the dam, and the two possible sires. Genotypes at 9 loci currently being assessed across the colony were determined using standard electrophoretic techniques (as shown in Table 1) for each of the seven animals sampled. The loci considered were third component of complement (C3), ceruloplasmin (Cp), glucose-phosphate isomerase (Gpi), peptidase A (PepA), peptidase D (PepD), 6-phosphogluconate dehydgrogenase (Pgd), phosphoglucomutase 1 (Pgm1), the X-linked locus thyroxinebinding globulin (Tbg), and transferrin (Tf).

The 9 loci typed showed variability in both families assessed for parentage determination, although only third component of complement (C3) and transferrin (Tf) exhibited more than 2 alleles within the colony (Table 1). Of these 9 loci, 4 were informative for assigning paternity among the animals considered. Table 2 presents the typing results for the informative loci in each of the families.

Table 2 : Genotypes at loci informative for parentage determination

These markers enabled resolution of paternity in both cases. In Family 1 the information available for the dam and the offspring indicated that the true sire had to carry an A allele at the Cp locus, a B allele at C3 , and an A allele at Tf since these alleles were present in the offspring but not in the dam. Both potential sires carried a B allele at C3 , but only the first sire (chimp3) carried the A allele at Cp and the A allele at Tf . Therefore, on the basis of two loci, Cp and Tf , we are able to assign paternity of chimp1 to chimp3 in Family 1.

The genetic data also allowed resolution of paternity in Family 2. Data available for the female offspring and the dam indicated that the true sire must carry a B allele at Cp , a C allele at C3 , a C allele at Tbg , and a D allele at Tf . The second sire (chimp7) carried all the required alleles, while the first sire could be excluded on the basis of C3 and Tbg . From these results we concluded that chimp7 was the sire of chimp5.


The results of these parentage analyses indicated that simple biochemical markers can suffice to resolve paternity issues in many cases. Although only two to five alleles per marker were found across the colony, the variability was still adequate to discriminate between the two potential sires in each case.

The value of standard genetic markers with clear biological interpretations, as opposed to more complex genotypes such as those generated by multilocus probes, should not be underestimated (VandeBerg, 1992). In addition to resolving parentage issues, standard genetic markers can be used in population structure assessments of the genetic variability present in a colony, in marker-marker linkage analyses, and in quantitative trait linkage analyses. The marker information generated in the genetic management program can thus enhance research opportunities by providing a rich resource to be utilized in combination with phenotypes assessed through research programs, and marker information generated by genetic studies of colony animals can be used by colony managers in genetic management programs. The availability of a common panel of markers, built up from various research and management activities for all animals in a breeding colony, allows routine monitoring and verification of the pedigree using software which checks for the presence of discrepant alleles in families [e.g., PEDSYS (Dyke, 1989)]. Such multipurpose utilization of genetic information generated by researchers and colony managers can greatly enhance the value of the colony for both breeding and research.

Assessing Group Housing for an Aged Female Rhesus Macaque

Jennifer Fligiel and Viktor Reinhardt

Wisconsin Regional Primate Research Center


In trying to maintain social housing for social animals in a laboratory or zoo, caregivers must continually monitor individuals' compatibility and suitability for group housing. Aging, because of its concomitant health problems, might change an individual's suitability for group living: some animals must be removed from the group permanently or just for treatment, while others might be more appropriately treated within the group. The present case study examines the impact of permanent group housing on the well-being of an aged female rhesus macaque (Macaca mulatta). The subject had a history of weight loss associated with diarrhea. This study attempted to determine if the weight loss was due to social stress.


The subject of this study was Ann, a 30-year-old rhesus macaque. She was the alpha female of a healthy breeding troop of 18 macaques housed at the Wisconsin Regional Primate Research Center (WRPRC). Besides Ann, the troop contained three adults (>12 years), including the alpha male; 7 young adults (6-12 years); three subadults (2-5 years); and four infants (<2 years). They lived as a breeding troop in an indoor pen 5.68 m deep, 2.48 m wide and 2.06 m high as described by Reinhardt (1992a). The group had visual contact with another troop housed under identical conditions in the same room. The animals were fed commercial monkey biscuits at 7:30, bread at 11:10, and fruit at 15:10. The biscuits were placed on the ceiling of the pen in such a way that the animals had to manipulate the biscuits through the wire mesh to obtain them (Reinhardt, 1992b). Enough were given so that they were available throughout the day. Water was available ad libitum.

This study addressed the following questions: Is Ann abused? Does she have access to food? What is her physical condition? The observational portion was subdivided into three parts.

1. Preliminary Study : J. F. became acquainted with the eighteen animals in the troop by observing them for 3 hours at a distance of 1 m from the wire mesh walls. The dominance order recorded by J. F. confirmed the order reported in a recently published paper (Reinhardt, 1992b).

2. Behavioral Observation: The troop was observed daily for 30-minute sessions equally distributed between 9:00 and 17:00 for 12 days. J. F. took written notes 1 m from the wire mesh walls. Interactions were recorded for analysis at a later time. Record sheets were divided into five-minute intervals and allowed simultaneous recording of Ann's location and behavior. Interpretation of behavior was based on the CCAC definitions of specific morphological postures, behaviors, and characteristics of non-human primates (CCAC, 1991).

3. Food Competition: J. F. placed bananas, raisins, or Gummy Bears on a 1 m-square area on the floor of the cage, a different treat every day, for three days, and recorded Ann's interactions with the other animals.

Ann's weight and medical history were obtained from the colony management computer at the WRPRC.


Analysis of agonistic interactions during the preliminary study clearly confirmed that Ann was the highest ranking female member of the troop. While she was subordinate to Niko (the alpha male), she remained dominant over all others, including her 14-year-old daughter Olga. Ann consistently yielded to Niko, who was never aggressive toward her.

Ann spent more time interacting with others (44 observations) than she did in self-oriented activities (4 observations). One of Ann's predominant behaviors was grooming. Subordinates were frequently observed grooming Ann, while she mainly groomed Niko and her daughter. In fact, Ann's primary association with Niko was grooming. Ann's most frequent interaction with subordinates was threatening them (17 observations); but she herself was threatened by a subordinate only once.

During all three food competition tests, Ann was one of the two dominant macaques. Only Niko obtained more food, and without any aggression toward Ann. Even before J. F. could place the food within the enclosure, Ann was sitting in front of all the others, and she remained between them and J. F. When subordinate members approached, Ann responded consistently with a threat. Any subordinate troop member who managed to obtain a piece of food left with it promptly. All of Ann's responses to subordinates were aggressive (e.g., slapping, lunging, biting, or staring). Subordinates' responses were consitently submissive (yielding, fear-grimacing, crouching).

Ann's medical history shows episodes of weight loss and diarrhea starting in January, 1991. On 12-14-90 her weight was stable at about 12 kg, and there had been no record of diarrhea. On 1-14-91 it was reported that she had watery diarrhea and anorexia. On that same day she received a dose of metronidazole. A second dose was administered the next day, when her weight was recorded as 8 kg. Ann had lost 1/3 of her body weight within a month. With daily supplemental feedings (Ensure @) over a 2-month period, her weight increased to 10.4 kg. One year later, Ann suffered several relapses of diarrhea and by 1-29-93 her weight had gone down to 6.9 kg. Metronidazole was again prescribed and administered daily until 2-3-93 when Ann's stool consistency was healthy. She reached 7.8 kg on 4-7-93, where she has stabilized. Ann presently receives supplemental feedings five times a week, which she readily accepts, and continues to receive Metronidazole as needed for non-specific diarrhea.


The aged female, Ann, maintained very high dominance rank, which guaranteed that she very rarely was a target of aggression. Her relationship with the alpha male showed no agonistic signs of tension. The behavior exhibited in the food competition clearly showed that she had the ability to obtain enough food. Other troop members respected Ann's status-related privileges, even in this highly competitive situation. Ann was also observed to have enough space to retire from the troop when she wanted to.

Weight loss such as Ann's has been observed in other aged macaques (Vertein & Reinhardt, 1993). Such weight loss can be critical if it progresses too quickly and goes unchecked. In the above-mentioned study supplemental feeding was shown to stop weight loss in all of the aged subjects (30 years and older).

Ann's role as an alpha animal, although potentially stressful, affords her the full benefits of being dominant, e.g., in food competition, where she can acquire enough to sustain herself. Because only one threat was observed toward Ann during this study, it appears that the potential of threatening behavior as a stressor in Ann's life in the troop is minimal. This was one of our main concerns regarding Ann's retention as a troop member. However, as a result of this study, we feel that Ann should be left with this highly cohesive group.

Primate Training and Enrichment Workshop Report

Ellen Messner
Tufts University School of Veterinary Medicine.

The fourth Primate Training and Enrichment Workshop was held in May 1994 by the University of Texas M. D. Anderson Cancer Center Science Park and Active Environments at the Science Park in Bastrop, TX. The enrichment part of the program was run by Mollie Bloomsmith and Steven Schapiro, while Gail Laule and Tim Desmond presented the training aspects.

More than half of the 31 participants work with captive primates in labs, as primary investigators, technologists, and caretakers. Zoo people and conservationists were also present, including a person who works at a chimpanzee sanctuary in Africa. The instructors did a nice job of identifying common needs among the diverse group, pointing out that the benefits of the program could be applied to the various levels of interaction and uses of primates represented.

We started with an overview of the definitions of training and enrichment, as well as the benefits and means of achieving them. In the afternoon we were shown the enrichment and training programs of the Science Park facilities, which include training chimpanzees to present body parts for inspection and to accept a number of veterinary procedures (e.g., thermometer use, blood draws, and urinating on cue for collection).

As an exercise we were presented with four situations, representing different aspects of primate management, including getting the animals to shift between cages and dealing with stereotypical behavior. We broke into groups, each working toward a solution for one of the prob- lems, to be presented on the last day.

We also worked in groups of four designing and building enrichment devices for chimpanzees or monkeys, which were tested by the primates of the Science Park. Results were presented to the entire group at the end of the workshop, along with the price of the materials. Some very creative low-cost projects resulted.

We also had a session called "The Training Game" in which we took turns training each other using only a clicking sound as a reward. Surprisingly, we learned as much being trained as training. Animal demonstrations and before-and-after videos showed how much can be accomplished with this tool. For future workshops, I suggest additional sessions of this training game, hands-on training of live animals, and an advanced course for those who had grasped the basics and were ready to learn the finer points.

The course cost $225 including most meals and transportation to and from the airport. One of the many pleasant things about this workshop was the friendliness and helpfulness of the people involved, from the primate caretakers to the facility administrators to the instructors.

Anyone involved in primate care and use would learn something in this workshop. Even people not involved in the daily hands-on aspects of primate care would profit from a better understanding of why enrichment and training are so important and how they can actually be a benefit to a primate facility, not just a requirement.

The Importance of Animals in Biomedical and Behavioral Research

A Statement from the Public Health Service

Virtually every medical achievement of the last century has depended directly or indirectly on research with animals. The knowledge gained from animal research has extended human life and made it healthier through many significant achievements, as illustrated by the following examples: vaccines to prevent poliomyelitis and other communicable diseases; surgical procedures to replace diseased heart valves; corneal transplants to restore normal vision; new medicines to control high blood pressure and reduce death from stroke; antipsychotic drugs to treat mental disorders; broad spectrum antibiotics to treat infections; and chemical agents to cure or slow childhood can- cers. Of course, there are many other diseases and disorders, such as AIDS, many forms of cancer, the common cold, Alzheimer's disease, schizophrenia, hepatitis, arthritis, cystic fibrosis, and brain and spinal cord injuries--just to name a few--for which no effective prevention, treatment, or cure now exists.

The use of living animals remains an important way to solve some medical problems. Researchers continually seek other models to understand the human organism, study disease processes, and test new therapies. In seeking more rapid and less expensive ways to obtain basic biological information that can be applied to human disease, scientists often study simpler organisms, such as bacteria, yeasts, roundworms, fruit flies, squids, and fishes. Researchers have spent decades learning how to sustain cells, tissues, and organs, from both animals and humans, outside the body to understand biological processes and develop new medical treatments. Mathematical, computer, and physical models complement animal experimentation as well. Although computers alone cannot produce new biological information, they enable scientists to analyze vast amounts of data and test ideas. In the end, the validity of the results obtained from these model systems must be verified in appropriate animal systems and, possibly as the final step, in clinical trials using human volunteers.

Like most people, scientists are concerned about animal well-being. Elaborate safeguards in the form of Federal laws have been implemented to ensure that institutions comply with the regulations and policies affecting the care and use of animals in research. Before beginning a project, all research proposals involving animals must be carefully reviewed and approved at each research facility by an Institutional Animal Care and Use Committee comprised of scientists, veterinarians, and private citizens. Veterinarians trained in laboratory animal medi- cine are responsible for observing and caring for animals, providing guidance to researchers, and overseeing institutional animal care pro- grams. In addition, institutions conducting animal research are routinely inspected by the U.S. Dept of Agriculture and monitored by the U.S. Public Health Service. Many institutions are further accredited by an independent evaluating body, the American Association for Accreditation of Laboratory Animal Care.

For more than a century, there have been organized groups and indi- viduals who have objected to using animals in biomedical research. This opposition has increased markedly in the last two decades. Animal activist organizations spurred by a philosophy that there is no moral justification for the use of animals in research--even to save human lives--have attempted to slow or halt the work of scientists, conduct mass demonstrations, or even commit acts of vandalism or terrorism. The few health professionals who support the activist movement stand apart from the vast majority of the nation's physicians, and most Americans readily accept the fact that animal research is necessary to achieve medical progress.

Institutions receiving support from the Public Health Service are obliged to adhere to the highest possible standards for the humane care and responsible use of laboratory animals. And scientists themselves have adopted the principle: "Good Animal Care and Good Science Go Hand in Hand." -- March 1994, by the Coordinating Committee on Animal Research

News Briefs

Update on Ivan Gorilla

Ivan is one of the gorillas who was featured in the 1990 National Geographic program, Urban Gorilla. Jane Dewar is an independent scholar who has visited many zoos in the U.S. and Europe. Keepers have permitted her to go "behind the scenes" and hand feed nearly 100 of the 375 gorillas she has "met." Her travels and meetings with gorillas and their keepers may give her a unique perspective and insight. She reports here on a visit this July, just before Ivan went into quaran- tine in preparation for his move to Zoo Atlanta this fall .

I had seen reports and articles about Ivan, the lonely gorilla housed at a huge flea market-type mall in Tacoma, WA. Photographs and stories led me to dread my visit to meet Ivan, with whom I had the honor of spending more than 2 days. I expected to see a decrepit, neurotic, and pitiful gorilla, but was elated to discover this was not at all the case.

I was surprised by how large (40' x 40') Ivan's main enclosure was, with running water, some ropes and a tire for climbing, and a heated floor (the latter may affect Ivan's ability to reproduce). Ivan also has a small outdoor enclosure (seen in the film "Urban Gorilla") and access to a converted truck trailer. Hay and burlap bedding was available in the outdoor and behind-the-scenes holding areas; Ivan made a nest to rest in while I was visiting him in the trailer.

Ivan is about 30 years old, captured as a baby in Africa. For most of his life he has lived apart from his species, so I was surprised to see how many typical zoo gorilla behaviors he displayed when we met. When I first saw Ivan, he was resting in his main exhibit, ignoring other store visitors who were trying to attract his attention. As Ivan looked up at me, I practiced my best gorilla manners, nodding my head while diverting my gaze. Ivan instantly stood up, came over for a closer look, and then began strutting around with stiff legs, tilted head, and short side glances as he alternated between tight lipped and open mouth staring, apparently trying to figure me out!

Later, as I met him behind-the-scenes, Ivan gently accepted fresh fruit and other treats I had brought, purring contentedly as he ate, despite apparently being in pain from several abcessed teeth (which were pulled later that week). Among the many zoo gorillas I have met, Ivan has one of the sweetest personalities. He seems very well-adjusted, enjoying the company of humans while maintaining his silverback dignity, despite his years of isolation from his own species. Nature won't give Ivan too much longer, but I have good feelings about his move to Zoo Atlanta, where perhaps, like Willie B. before him, Ivan will show the world how resilient, tolerant and special gorillas can be. -- Jane Dewar, 11622 West 87th Street, Burr Ridge, IL 60521

Philippine Export Ban

According to a story in Animal People , a Philippine official confirmed that the country will ban the export of both wild-caught and captive-bred nonhuman primates later this year. The promise to stop the export of wild-caught animals was made in 1986 and the phase-out began in 1989. The inclusion of captive-bred animals under the ban was linked to easing the burden of enforcement because officials would not have to determine where each animal was born. -- From the June 9, 1994 NABR Update.

New Director at Yerkes RPRC

Thomas R. Insel, M.D., most recently head of the NIMH Unit of Developmental Biopsychology, NIH, has been named seventh director of the Yerkes Regional Primate Research Center at Emory University. He follows Frederick A. King, Ph.D., who retired after heading Yerkes since 1978. Insel, who describes himself as a "psychiatrist turned neuroscientist," will have a joint appointment in Emory's Dept of Psychiatry and Behavioral Science.

Although much of his earlier work involved both human and nonhuman primates, including rhesus and squirrel monkeys, in the past five years Insel has worked mostly with rodents to study the cellular and molecular basis of social behaviors. These studies have demonstrated an important role for the neuropeptides oxytocin and vasopressin in the formation of social bonds. Now he hopes to investigate these same mechanisms in the primate brain.

More Golden Lion Tamarins Discovered

An estimated 290 golden lion tamarins live in Poço das Antas Biological Reserve, the only federal reserve set aside by the Brazilian government to protect the species. An additional 550 are found in research institutions and zoos. Cooperating zoos have released 120 captive-born tamarins onto private farms near the Poço das Antas reserve, which is too small to shelter the extra animals.

Using satellite imagery, World Wildlife Fund-supported researcher Cecilia Kierulff recently located 266 golden lion tamarins in remote areas of Brazil's Atlantic Forest. In 1992 Kilrulff began using Landsat TM5 remote sensing images to identify patches of forest outside the reserve that correspond to the tamarins' habitat. Next, she interviewed local inhabitants to discover which areas actually were inhabited by the animals. Finally, she played recordings of "group meeting" calls to attract the tamarins at likely locations. -- From Focus, 1994 , 16[ 3 ].

Information Requested and Available

Pet Monkey Information

Cathy A. Johnson-Delaney, of the Primate Information Center at the University of Wisconsin, published a comprehensive paper in Exotic Pet Medicine II (1994, 24 , 121-156) covering information and advice for the small animal practitioner who occasionally sees a non-human primate pet. This paper would be a good reference for primatologists to pass on to such veterinarians who consult them.

International Directory of Primatology

The Wisconsin Regional Primate Research Center, University of Wisconsin--Madison, has just published the second edition of their International Directory of Primatology, to enhance communications among the many organizations and individuals involved in primate research, conservation and education. It can be used by primatologists as a desktop working tool or by librarians and other professionals who need to answer questions or direct students to primate programs or other information resources.

The directory is divided into four sections and five indexes. The sections cover (1) geographically arranged entries for major primate centers, laboratories, educational programs, foundations, conservation agencies and sanctuaries, (2) groups involved with nonhuman primate population management, (3) professional primate societies, including the membership roster of the International Primatological Society, and (4) major information resources in the field. Access to this information is supported by organizational, field site, species, subject and name indexes.

Copies of the International Directory of Primatology--354 pp., spiral bound--are available in the USA for $15 (includes surface postage and handling). To offset mailing costs, the price to other countries is $23, payable in US dollars. Orders to: Larry Jacobsen, IDP Coordinator, WRPRC Library, 1220 Capitol Ct., Madison, WI 53715-1299 [608-263-3512; FAX: 608-263-4031; e-mail:].

All-Male Social Group Formation

In the article "All-Male Social Group Formation: Does Cutting Canine Teeth Promote Social Integration?" by M. R. Clarke & J. L. Blanchard (1994, 33 [2], 5-8), the third paragraph in the "Methods" section should read as follows:

Procedure: Subjects were paired by age, weight, and number of removals from all-male or mixed social groups. One male from each pair was assigned to the experimental group (canines to be cut), and the other male from the pair was assigned to the control group (canines intact). The 13 males in the experimental group were treated with procaine penicillin G for five days, starting one day prior to the procedure. The monkeys were anesthetized with ketamine hydrochloride (10mg/kg) and acepromazine (0.1 mg/kg). The mouth was washed thoroughly with Nolvasan, and a diamond burr was used to cut all 4 canine teeth at the level of adjacent teeth. The pulp cavity was opened to a depth of 2-3 mm, packed with calcium hydroxide, and filled with amalgam. Animals were then allowed 5 days to recover from the procedure.

Spanish Primatology Association

The names of some of the officers of the Spanish Primatology Association were misspelled in the last issue. They should be Joachim Veá, Vice-President; Fernando Pelaez, Secretary; Maribel Baldellou and Juan Carlos Gómez, Officers for Research; Carmen Maté and Francisco Gómez, Officers for Conservation and Well-being.

Animal Models

*Early colonic damage and invasion of Campylobacter jejuni in experimentally challenged infant Macaca mulatta. Russell, R. G., O'Donnoghue, M., Blake, D. C., Jr., Zulty, J., & DeTolla, L. J. (Prog. of Comp. Med., Rm G-100, Med. School Teaching Fac. Bldg, 10 S. Pine St, Baltimore, MD 21201). Journal of Infectious Diseases , 1993, 168, 210-215.
. . Two 3.5-month-old rhesus, kept in one cage, developed diarrhea 32 hours after one was challenged with C. jejuni orally. Both infants were culture-negative on day 17. Electron microscopic observations indicated that cell invasion was the primary mechanism of colon damage and diarrheal disease. C. jejuni invade cells in the superficial layers of the colonic epithelium and initiate degenerative changes resulting in mucosal damage, with loss of cells from the luminal surface and erosion with diarrhea.

*Neonatal disease induced by SIV infection of the rhesus monkey (Macaca mulatta). Bohm, R. P., Jr., Martin, L. N., Davison-Fairburn, B., Baskin, G. B., & Murphey-Corb, M. (Dept of Vet. Sciences, Tulane RPRC, Covington, LA 70433). AIDS Research and Human Retroviruses , 1993, 9 , 1131-1137.
. . Mean survival time after inoculation in 3-day-old infants is considerably shorter than in animals inoculated as juveniles, and a greater percentage of infected animals demonstrated persistent antigenemia and progressive disease. A decline in the CD4+CD29+ lymphocyte subset may be a more reliable early indicator of progressive disease and early death than declining CD4+ percentages in the SIV-infected neonate.

*Profound systemic hypothermia protects the spinal cord in a primate model of spinal cord ischemia. Rokkas, C. K., Sundaresan, S., Shuman, T. A., Palazzo, R. S., Nitta, T., Despotis, G. J., Burns, T. C., Wareing, T. H., & Kouchoukos, N. T. (N. T. K., Dept of Surgery, Jewish Hospital, Washington Univ. Med. Center, 216 S. Kings- highway Blvd, St. Louis, MO 63110). Journal of Thoracic and Cardiovascular Surgery, 1993, 106 , 1024-1035.
. . Six survivors of hypothermic aortal clamping were neurologically intact, while all eight survivors of a normothermic equivalent procedure were paraplegic or paraparetic. Profound hypo- thermia produced by hypothermic cardiopulmonary bypass may be an effective method of protection of the spinal cord in patients undergoing repair of aneurysms of the thoracoabdominal aorta and may reduce the prevalence of ischemic injury to the spinal cord.

*HDL as a protective factor against coronary artery atherosclerosis evidence from pathology in experimental animals. Rudel, L. L. (Dept. of Biochem. & Comp. Med., Bowman Gray School of Med., Medical Center Blvd, Winston Salem, NC 27157-1040). Cardiovascular Risk Factors , 1993, 3 , 262-269.
. . A review of data from correlative studies relating HDL cholesterol concentration in blood plasma to coronary artery atherosclerosis. The data in nonhuman primates strongly support the hypothesis that HDL protect against development of coronary artery atherosclerosis, although the data indicate that HDL assume a more important role when LDL have become atherogenic.


*Prenatal stress exposure alters postnatal behavioral expression under conditions of novelty challenge in rhesus monkey infants. Schneider, M. L. (Dept of Therapeutic Science, 2175 Med. Science Center, 1300 University Ave, Madison, WI 53706-1532). Developmental Psychobiology, 1992, 25 , 529-540.
. . Infants of mothers mildly stressed during pregnancy demonstrated more disturbance behavior, and lower levels of gross motor/exploratory behavior, than infants of unstressed mothers. Moreover, half of the prenatally stressed infants showed an abnormal response, falling asleep, while none of the control infants displayed this behavior.

*Food search demand effort effects on behavior and cortisol in adult female squirrel monkeys. Champoux, M., Zanker, D., & Levine, S. (NIH Animal Center, P.O. Box 529, Poolesville, MD 20837). Physiology & Behavior , 1993, 54 , 1091-1097.
. . Animals were exposed to feeding conditions in which the availability and accessibility of food were altered. A high-demand condition offered 120% of normal daily intake buried in wood chips; variable-demand alternated this condition with a low-demand, in which 600% of normal daily intake was offered in the same way. In the variable- demand condition, plasma cortisol was elevated above baseline during the periods of high effort, while the other group's plasma cortisol was elevated throughout the experiment. Contact with other animals, as well as a species-specific inactive posture, decreased as a result of exposure to high demand. The imposition of increased food-seeking efforts provides an ecologically relevant and noninvasive method of producing chronic stress in the squirrel monkey.

*Immature siblings and mother-infant relationships among free-ranging rhesus monkeys on Cayo Santiago. Berman, C. M. (Dept of Anthropology, SUNY, Buffalo, NY 14261). Animal Behaviour , 1992, 44 , 247-258.
. . Data for 124 mother-infant pairs suggest that mothers with one or more immature daughters in addition to their infants are in contact with their infants less than those with no immature daughters. High-ranking mothers with older immature daughters also reject their infants significantly more than those without older daughters, and tend to begin mating earlier in the mating season. The presence of sons has relatively little impact on mother-infant interaction, or on the timing of the mother's resumption of mating.

*Foraging behavior of a tamarin group (Saguinus fuscicollis weddelli) and interactions with marmosets (Callithrix emiliae). Lopes, M. A. & Ferrari, S. F. (Dept. Zoologia, Museu Goeldi, Caixa Postal 399, 66.040-970 Belem-PA, Brazil). International Journal of Primatology , 1994, 15 , 373-387.
. . Association between the two species appeared to be less systematic overall than those observed between S. fuscicollis and congeners at other sites. Whether and to what extent C. emiliae benefits from the presence of S. f. weddelli are questions that require additional study.


*Introduction and integration of strangers into captive groups of tufted capuchins (Cebus apella). Fragaszy, D., Baer, J., & Adams-Curtis, L. (Dept of Psychology, Univ. of Georgia, Athens, GA 30602-3013). International Journal of Primatology , 1994, 15 , 399-420.
. . Results indicate that, in this species: 1) introductions of adult females can be carried out with acceptable risk to the newcomers provided that careful monitoring occurs; 2) juveniles can be introduced with minimal risk; 3) adult males can be introduced into groups lacking resident adult males with minimal risk. Capuchins differ in important ways from Old World monkeys in their response to introductions of strangers.

*The effects of food treat provisioning and human interaction on the behavioral well-being of rhesus monkeys (Macaca mulatta). Bayne, K. A. L., Dexter, S. L., & Strange, G. M. (Behavior & Nutrition Unit, Vet. Resources Program, NCRR, NIH, Bethesda, MD 20892). Contemporary Topics , 1993, 32 [2], 6-9.
. . Investing extra time (2 minutes per subject, 3 times a week) with rhesus monkeys, using their signals for communication, and providing supplementary food can result in a significant reduction of certain undesirable behaviors. The effects of this program appear to continue for at least a 10-week post-experimental period.

*Caged rhesus macaques voluntarily work for ordinary food. Reinhardt, V. (4605 Crescent Rd, Madison, WI 53711). Primates , 1994, 35 , 95-98.
. . Animals given a choice of freely collecting their standard food ration from an ordinary food box or working for its retrieval from a custom-made food puzzle spent on average a total of 32 sec retrieving 29 biscuits from the box, and 673 sec getting 11.3 biscuits from the puzzle.


*Differential growth among components of the palate in rhesus monkeys (Macaca mulatta). King, A. H. & Schneiderman, E. D. (E. D. S., Baylor College of Dentistry, Dept of Oral & Maxillofacial Surgery, 3302 Gaston Ave, Dallas, TX 75246). Cleft Palate-Craniofacial Journal , 1993, 30 , 302-308.
. . Measurement of 108 male and 107 female skulls, ranging in age from 1 to 7 years, suggest that sutures of the midface, in particular the transverse palatine suture, may be important in the bony development of the palate during growth. These sutures may contribute to the overall modulation of palatal development. The greater midfacial prognathism seen in adult rhesus males than in females may be associated with increased relative growth of the palatine segment during puberty.


*Nonhuman primate tularemia (Francisella tularensis) epizootic in a zoological park. Calle, P. P., Bowerman, D. L., & Pape, W. J. (Animal Health Ctr, NYZS, 185th St & Southern Blvd, Bronx, NY 10460). Journal of Zoo and Wildlife Medicine , 1993, 24 , 459-468.
. . Twelve nonhuman primates of 4 species (Varecia v. variegata, Lemur catta, Hylobates-lar, and Cercopithecus n. nictitans) developed typhoidal tularemia during a 6-week epizootic. An additional 13 asymptomatic primates housed with or adjacent to symptomatic animals were prophylactically treated and did not develop illness. Seventy-three primates in the facility were not treated and did not develop tularezootic, many house mice had been found dead in the building in which the primates were housed. The likely infection route was through the ingestion of food that had been contaminated by mouse feces, urine, or saliva after it was distributed to the enclosures. The epizootic was controlled by antibiotic treatment of ill and potentially exposed primates, management and husbandry alterations designed to decrease rodent access to primate diets, and elimination of rodent vectors.

*Vaccination of chimpanzees against infection by the hepatitis C virus. Choo, Q.-L., Kuo, G., Ralston, R., Weiner, A., Chien, D., Van Nest, G., Han, J., Berger, K., Thudium, K., Kuo, C., Kansopon, J., McFarland, J., Tabrizi, A., Ching, K., Moss, B., Cummins, L. B., Houghton, M., & Muchmore, E. (M. H., Chiron Corp., 4560 Horton St, Emeryville, CA 94608). Proceedings of the National Academy of Sciences, U.S.A. , 1994, 91 , 1294-1298.
. . Seven chimpanzees were immunized with both putative envelope glycoproteins [E1 (gp33) and E2 (gp72)] that were copurified from HeLa cells infected with a recombinant vaccinia virus expression vector. A strong humoral immune response was obtained in all vaccinees. The five highest responders showed complete protection against an I.V. challenge with homologous hepatitis C virus 1. The remaining two vaccinees became infected, but both infection and disease may have been ameliorated in comparison with four similarily challenged control animals, all of which developed acute hepatitis and chronic infections.

*Variation in course of hepatitis E in experimentally infected cynomolgus monkeys. Tsarev, S. A., Emerson, S. U., Tsareva, T. S., Yarbough, P. O., Lewis, M., Govindarajan, S., Reyes, G. R., Shapiro, M., & Purcell, R. H. (LID/NIAID/NIH, Bldg 7, Rm 200, 9000 Rockville Pike, Bethesda, MD 20892). Journal of Infectious Diseases , 1993, 167 , 1302-1306.
. . Five monkeys developed hepatitis after inoculation with a prototype strain of hepatitis E virus. For 4 monkeys, increased alanine aminotransferase (ALT) activity was first observed on days 21-26, viremia occurred before and during enzyme elevation, and the animals seroconverted coincidentally with the end of viremia or shortly thereafter. The fifth animal had a more severe hepatitis, with peak ALT values more than twice the peak levels of the others. This animal developed biphasic hepatitis with peaks of ALT activity on days 26 and 54; viremia and seroconversion were correlated only with the second peak of enzyme elevation and liver histopathology only with the first peak. Viral shedding in this fifth animal lasted twice as long as in the others.

*The incidence of senile plaques and multiple infarction in aged macaque brain. Uno, H. (Wisconsin RPRC, 1223 Capitol Ct, Madison, WI 53715). Neurobiology of Aging , 1993, 14 , 673-674.
. . Examination of 51 brains from rhesus monkeys 25 to 36 years old showed the incidence of senile plaque in 20-30-year-old animals is between 40-66%; in monkeys older than 31 years, the incidence increases to 71%. The most common areas for plaques are in the basal prefrontal region and the amygdala. Multiple infarction in the aging monkey appears to be rare.


*Maintenance of genetic variability in a specific pathogen-free breeding colony. Ely, J. J., Manis, G. S., Keeling, M. E., & Stone, W. H. (Dept of Biology, Trinity Univ., 715 Stadium Dr., San Antonio, TX 78212). Laboratory Animal Science , 1994, 44 , 211-216.
. . Comparison of 18 genetic loci in a SPF colony and the non-SPF population from which it was derived showed no change in the average gene diversity between the populations. However, gene diversity at blood group Q locus increased significantly in the SPF population, while blood group M locus showed an insignificant trend toward decreased gene diversity.

Instruments & Techniques

*Xenotransplant-associated zoonoses: Strategies for prevention. Michaels, M. G. & Simmons, R. L. (Children's Hospital of Pittsburgh, Infectious Diseases, 3705 Fifth Ave at De Soto St, Pittsburgh, PA 15213). Transplantation , 1994, 57 , 1-7.
. . An overview of specific infectious organisms found in baboons and swine, the animals most often viewed as xenotransplant donors, and potential preventive strategies.

*Repair of temporomandibular joint disc perforation using a synovial membrane flap in Macaca fascicularis monkeys: Light and electron microscopy studies. Sharawy, M. M., Helmy, E. S., Bays, R. A., & Larke, V. B. (Dept of Oral Biology, School of Dentistry, Med. College of Georgia, Augusta, GA 30912). Journal of Oral and Maxillofacial Surgery , 1994, 52 , 259-270.
. . Surgical repair of experimentally perforated discs reversed degenerative alterations, which persisted in matched unrepaired discs.


*Maternal dietary zinc influences DNA strand break and 8-hydroxy-2'-deoxyguanosine levels in infant rhesus monkey liver. Olin, K. L., Shigenaga, M. K., Ames, B. N., Golub, M. S., Gershwin, M E., Hendrickx, A. G., & Keen, C. L. (C. L. K., Dept of Nutrition, Univ. of California, Davis, CA 95616). Proceedings of the Society for Experimental Biology and Medicine , 1993, 203 , 461-466.
. . Infants born to monkeys fed low zinc diets are characterized by evidence of DNA damage shortly after birth; this damage may be due to an increased rate of oxidative damage and/or a reduction in the rate of DNA repair.


*Dose-dependent suppression of aqueous humor formation by timolol in the cynomolgus monkey. Robinson, J. C. & Kaufman, P. L. (P. L. K., Dept of Ophthalmology, Univ. of Wisconsin, Clinical Sci. Center, 600 Highland Ave, Madison, WI 53792). Journal of Glaucoma , 1993, 2, 251-256.
. . Timolol doses as small as 2.5 microg can suppress aqueous formation by a statistically significant 20%. In the monkey, as in the human, timolol is a far more potent suppressor of aqueous formation than is generally realized, and standard clinical doses may in fact be overdoses in both species.


*Suppression of luteinizing hormone secretion during short-term fasting in male rhesus monkeys: The role of metabolic versus stress signals. Schreihofer, D. A., Parfitt, D. B., & Cameron, J. L. (J. L. C., Dept of Psychiatry, School of Med., Univ. of Pittsburgh, 3811 O'Hara St, Pittsburgh, PA 15213). Endocrinology , 1993, 132 , 1881-1889.
. . Results support the hypothesis that the signal(s) which suppresses normal LH secretion after brief periods of fasting is related to the metabolic status of the body during the transition from a fed to a fasted state, rather than a function of the psychological state imposed by withholding food.

*Hypoglycemia-induced inhibition of luteinizing hormone secretion in the rhesus monkey is not mediated by endogenous opioid peptides. Heisler, L. E., Pallotta, C. M., Reid, R. L., & Van Vugt, D. A. (D. A. V. V., Dept of Ob-Gyn, Etherington Hall, Queen's Univ., Kingston, P.O. Canada K7L 3N6). Journal of Clinical Endocrinology and Metabolism , 1993, 76 , 1280-1285.
. . Infusion of naloxone did not reverse the effects of insulin-induced hypoglycemia on LH concentrations. Hypoglycemia inhibited LH levels only during a period of restraint, suggesting either an additive or synergistic effect of the two stresses on LH secretion.

*Role of postural status in the nocturnal hemodynamic patterns of nonhuman primates. Engel, B. T., Talan, M. I., & Chew, P. H. (Lab. of Behavioral Sciences, NIA, Gerontology Research Ctr, 4940 Eastern Ave, Baltimore, MD 21224). Journal of Applied Physiology , 1993, 74, 1684-1688.
. . A consistent hemodynamic pattern characterized by an overnight fall in cardiac output and central venous pressure and a rise in total peripheral resistance that maintained blood pressure homeostasis was found in tethered monkeys as well as in chaired ones. Because the pattern occurred under both conditions, it is likely that it is a stable biologic effect, which is probably related to an overnight loss in fluid volume that is not replaced in animals that sleep throughout the night.


Climate and reproductive seasonality in two free-ranging island populations of rhesus macaques (Macaca mulatta). Lehman, S. M., Taylor, L. L., & Easley, S. P. (L. L. T., Dept of Anthropology, P.O. Box 248106, Univ. of Miami, Coral Gables, FL 33124). International Journal of Primatology , 1994, 15 , 115-128.
. . Examination of 3 years of records from two populations living on Florida keys does not substantiate the hypothesis that the onset of rainfall, within the temporal period set by photoperiod, regulates seasonal reproduction in rhesus macaques. Reproductive seasonality in the study populations may be influenced by a variety of factors.

*Multiple breeding females in free-ranging groups of Callithrix jac- chus . Digby, L. J. & Ferrari, S. F. (Dept of Anthropology, Univ. of California, Davis, CA 95616). International Journal of Primatology , 1994, 15 , 389-397.
. . Evidence was found of simultaneous presence of two reproductively active females in each of three monitored groups. At least one conception and birth was recorded for two females in each group, but other adult females did not breed. Comparisons with data from other sites indicate that the presence of a second breeding female in a group may be related to high population density, though the underlying mechanisms remain unclear.

*Suppressed copulatory behavior and ovarian function in lactating Japanese monkeys (Macaca fuscata fuscata) during the mating season. Mitsunaga, F., Nozaki, M., & Shimizu, K. (Primate Research Inst., Kyoto Univ., Kanrin, Inuyama, Aichi 484, Japan). Primates , 1994, 35 , 79-88.
. . The low sexual activity of lactating female Japanese macaques is clearly correlated with low levels of plasma estradiol due to suppressed ovarian function.
