Wooden Objects for Enrichment: A Discussion

On February 11, Viktor Reinhardt asked the Primate Enrichment Forum (PEF), “Does anyone have experience with wooden objects for environmental enrichment?” Here are some of the responses, with permission from the respondents and the PEF-list owner, David Seelig.

Katie Eckert, University of San Francisco:
We do not currently use wood with our Old World monkeys. The vets gave the following reasons: *difficult to sanitize and keep clean *risk of splinters, choking, or other harm *wooden perches can't be used in squeeze cages (we use folding perches from BioEnvironmental Modifiers). We do use manzanita branches in the cages for our common marmosets and squirrel monkeys. They get constant, heavy use as perches, and the marmosets gouge mercilessly on the branches for scent marking.

We also use pine/oak dowels in sections on 2-ft stainless steel threaded rods as gum feeders (originally purchased from K.L.A.S.S., but now manufactured in-house). Each dowel section has five holes drilled in to it close to the surface which are filled monthly with acacia gum purchased from Bioserv. The marmosets use these for perching and scent-marking as well as chewing through the “bark” to access the gum, and I would say that it's by far the most successful and heavily used enrichment we have for them. None of these wood products have ever caused health problems or clogged drains that I am aware of.

Carol Niemeyer, Oregon RPRC:
We give some of our rhesus macaques pieces (about 6” long and 1” to 1½” in diameter) of cherry wood and/or vine maple. It is perhaps their favorite toy. Most accept it immediately, and begin peeling the bark. It can plug our smaller, older drains, so in those areas we place a screen under the monkey's cage. Screening is cut to approximately the size of the bottom of the cage, and the edges are dipped in “Plastidip”, a type of paint, to cover the sharp edges and prevent injuries to staff or animals. Wood dropped on the screen is dumped into the trash.

Rather than risk plugged drains by giving wood to many animals in one area, we usually provide wood to those monkeys who would benefit most from the extra enrichment, e.g., overgroomers. I also give pieces of wood to each monkey during pairings in which the monkeys being paired are especially tense, so that they can redirect their tension. In those cases, I recommend against placing screens under the cage during the pairing, to avoid further frightening the monkeys, and suggest cleaning up the dropped wood by hand later.

There has not been a problem noted with mold. The monkeys peel or chew the wood down to small bits pretty quickly, and any leftovers are removed when a new piece is given, usually within a month.

One concern: very rarely a monkey will actually swallow bits of wood, as is possible with many chewable toys. It is important to watch for pieces of wood in the feces, and discontinue giving wood to that monkey. I have only seen this once in maybe four years, however.

We do not use wooden perches, because of the drains and the concern about keeping a larger piece of wood sanitary enough to avoid transmission of bacteria.

I feel that wood is one of the favorite enrichment items of the monkeys, perhaps due to its naturalness. If you want to receive a sample of cherry wood or vine maple to try with your monkeys, contact the person who supplies ours: Mike Cook, e-mail address: <[email protected]>>.

I worked in a lab in England which had wooden perches and swings for the rhesus macaques. The monkeys constantly chewed on the perches until they were completely destroyed and had to be replaced. Then the destruction process would start all over again. The monkeys never lost interest in the perches. The only trouble we had was that as the monkeys chewed the wood away the nails holding the perch together were exposed. We had to keep a careful eye out for this and remove the nails before the monkeys could. We made swings out of both branches and wooden planks. The monkeys used to chew on those as well, but not as much as the perches.

We never had any health problems as a result of the wood nor was sanitation a problem. However, we had only four monkeys. We could keep very good watch on what was happening with the swings and perches. I would recommend using wooden objects for enrichment only on a small scale and in carefully monitored environments.

Rachel W. Rogers, Parrot Jungle and Gardens:
In many of the zoos I have worked in, wood is used in the form of live plants and cut branches for perching. Apes, prosimians, New World and Old World species all receive wooden toys and branch segments. The types of trees used are pine, eucalyptus (cut branches only – not growing trees), oak, ficus sp., walnut, pecan, and Indian laurel trees, to name a few. Also store-bought untreated timbers, plywood, and various sized wood planks.

With respect to health problems for the animals, it is wise to consult with the vet staff about disinfection protocols, particularly for species that scent-mark their environment. Any chemicals remaining on the wood may be harmful.

Some prosimians would not only scent-mark the wood, but also use their teeth to mark grooves. They would also perch on the wood more than on metal objects in their enclosures. This may have been for comfort – metal or cement conduct heat and cold more than wood does.

Some animals lost interest in the wooden objects. At first they were very busy removing bark. Some of the branches would have insects, which the primates ate. It seemed their interest would decline after all the bark was removed.

We recommend this kind of enrichment, but if using food with the wooden objects, it is important to consider how to clean food off the wood. Cleaning gum from a gum feeder is different than cleaning a raisin board.

Jurgen Seier, Experimental Biology Programme Primate Unit, South Africa:
We have been using wood extensively in our vervet monkey facility (about 300 monkeys, indoors), and in our communal cages we make climbing apparatus from wood. Wood perches for resting were also installed but they use the metal perches equally. The vervets use the wood as described for other species, gnawing, stripping the bark and climbing. They eventually reduce smaller and medium branches to a single pole. We find this destruction desirable since it keeps them occupied for hours. We install some branches horizontally so that they can still move a bit. The vervets do not lose interest in the wood as they do in other inanimate objects which we have tried. Particularly the adults have not been all that keen to “fiddle” with various loose objects which we have placed inside the cages. There is obviously the problem of sanitation but we replace the wood regularly and autoclave it before we place it inside the cage (luckily we have a very large autoclave). Neither clogging of drains nor mold has occurred; nor have injuries. We also drill holes into short stubs of wood, fill them with soft food items and give them to individuals which have to be singly caged for a time (in projects). When they finish poking the food out, they gnaw the wood. However, not all use this with the same amount of interest. The stubs are autoclaved regularly and eventually discarded and replaced. We consider wood our most important enrichment tool.

Bob Ingersoll and Linda Barklay, Mindy's Memory Primate Sanctuary:
Here at the Sanctuary (see <>) we use apple, peach, and maple branches as much as our trees permit. We also use some native blackjack oak. The monkeys don't eat the wood, but do strip the bark off. The maple holds up quite well. We also use bamboo when we can and the monkeys seem to enjoy it. We use lumber from the local hardware store as necessary for perches and runs above ground that we construct inside our enclosures. We also use plywood for constructing above-ground platforms and outside warming houses. The monkeys do not chew on the plywood. We also use landscape timbers to construct climbing structures.

Cobie Brinkman, Australian National University:
For socially housed juvenile Macaca nemestrina and adult male M. fascicularis, we use wooden objects for enrichment, as well as wooden perches made from hardwood. The latter may be solid but the animals prefer seats made of two or three 2” slats spaced 2-3” apart, with rounded edges to the top surface, since these allow the animals to sit more comfortably, and in a more natural position (especially fascicularis, which tend to sit with rounded back when relaxed; they “rest” their ischial callosities against the rear edge of one slat, with the tail hanging down in the space in between). Using round poles might be even more comfortable, as this shape was preferred in our steel perches but round wooden poles are not only expensive but also hard to fix.

We give our animals wooden toys, made of a medium-soft wood, red cedar, since (untreated) pine was too soft. For no particular reason, our workshop made these toys in the shape of a barbell, with 4” diameter, 2” thick discs at each end. The discs taper into a 4” long, 1-1.5” thick central handhold (grip). The animals manipulate them, carry them, and chew them, pulling off slivers of wood (why pine was too soft!), but were never observed to ingest wood. Note though that cedar may cause changes in liver enzymes if ingested! My monkeys, who had many enrichments available, used to love the wooden toys and spent a lot of time with them, reducing them to kindling slivers in little more than a week, a much more intensive use then that reported by Reinhardt for his “gnawing sticks”. Differences include shape, type of wood, and availability, with our animals receiving these toys irregularly. Other animals, given hard wood blocks (4x4x6”) would only use them to sit on, with an occasional chew at the (rounded) edges. These blocks were rather too heavy and chunky for easy “transport” and manipulation.

Our animals occasionally receive willow or poplar branch segments as browse. However, in all our social cages, hardwood branches are used to provide climbing opportunities. Branches are attached to the cage walls and to each other with loops of metal wire; some to thick chains which themselves are clipped onto the cage walls. By moving the clips and chains, the environmental structure can be changed easily to provide new challenges. Some horizontal branches on chains are suspended with a strong coil spring between chain and clip. Such branches bounce when animals jump on them and I like to think this mimics real forest life! Adult males use these trampoline branches in dominance displays.

The animals' “woodchipping” activities with their toys left a lot of debris. First sweeping and removing debris from the floor, then covering the drain with a mesh when hosing prevented serious clogging of the drains. Since cleaning was daily, there never was mold; nor did mold develop on “left over” toy bits, or on wooden cage fixtures. We have not observed any health problems, but note the caveat on use of cedar if doing metabolic studies.

Our animals only lost interest after the barbells had been just about reduced to a small lump! Given intermittently, they were of continued interest, and used, over several years.

Our macaques certainly seemed to enjoy the wood as toys, but I don't know if they are superior to other toys. Large plastic bottles could be given every day, with food items sometimes in them, and never clog drains; you only have to pick up the pieces. As to the slat-like perches, there is probably no advantage over steel fittings, design being more important than material. However, having a “natural” climbing frame with odd angles that changed, and different shapes and diameters, plus bounce, seems to improve and enhance locomotion. In addition, branch forks were favored perching sites. Little or no gnawing was done on these branches (rock hard! mostly sundried redgum used here for termite-proof, just about everlasting, fence posts and railway sleepers [“ties” in the U.S. Thanks to Track Maintenance Equipment Ltd, of Surrey, for clearing this up for us– Ed.]).

Sophie Oliver, Auckland Zoo:
We use wood a lot for enrichment at the Zoo, partly because it is readily available and cheap, and also because it is natural, so it works well in naturalistic exhibits.

Gibbons, orangutans, chimps, squirrel monkeys, macaques, and spider monkeys get logs with holes drilled out and packed with small fruit pieces, rice, popcorn, or a müseli-type mixture. For the smaller species (lemurs, tamarins, and squirrel monkeys), bamboo pipes can be suspended in the enclosure for artificial gum feeders and food dispensers (also good for dispensing insects such as mealworms). This works well for using fingers and tools to extract the food. Perhaps plugs are necessary for the chimps and orangutans now that they are pretty efficient at removing the contents.

All our primates have wooden perches, trees, or branching and climbing apparatus made from wood.

We give rotten logs with grubs in them to the siamangs, macaques, chimps, orangutans, and lemurs. They are investigated and ripped apart even if the contents aren't always eaten. Large branches for browse are put into all enclosures and even unused/unsold Christmas trees have been given to the chimps to investigate.

Any wood that is nontoxic is fine; our horticultural team helps with this. We get untreated scrap wood from carpenters or from trees which must be removed from the grounds. Wooden perches are cleaned daily with a low-hazardous cleaner. When necessary they are water-blasted or cleaned with a stronger disinfectant. Swinging branches work well, mainly for spider monkeys and siamangs, but have not been used extensively at the Zoo.

Having lots of branches available makes it easy for us to spear whole fruits onto them and to hide food in bark creases, etc., providing more interest and increased activity within the exhibits, e.g., for lemurs, squirrel monkeys, and tamarins.

Of course the animals would lose interest in the objects if they were left in the enclosures for good (just as a human child would). So it is important for the items to be rotated and modified to encourage use. We generally provide wooden toys and remove them within 24 hours, so they can be cleaned and filled for someone else!

The only problem we have had with any wooden item is that the chimps have a habit of throwing hefty objects about, and so we give them loose wooden objects only when they are in their inside dens.

I cannot see any reason why well-chosen wooden objects should not be used as part of an enrichment scheme. They can be cleaned like any other item and we have not experienced hygiene or behavioral problems as a result. One thing to ensure is that there are enough enrichments for all of the animals in an exhibit – if there is not much else for the animals to do, competition might result.

Cindy Buckmaster, SUNY, Stony Brook:
We've been giving our colony Wisconsin Gnawing Sticks (red oak branches) for months. They adore them and spend quite a bit of time biting and peeling them. We replace them every three months and have had no problems with health or clogged drains. They've also been given to other monkeys in our facility that were chronically exhibiting self-injurious behavior, and the sticks seem to have helped. As for my boys, they love them.

Lisa Knowles, Wisconsin RPRC:
All of the rhesus macaques housed at the WRPRC (approximately 1300) have full-time access to wood on a regular basis. We use sections of red oak, which are very popular with the monkeys and cause almost no drain problems and no health problems. We are however, careful about presenting wood to animals who have pre-existing health conditions that might be exacerbated. Our monkeys make the most use of the wood in the first few days after they receive a new piece (we change wood every three months, or sooner if necessary). After the first few days the animals still make use of the wood as cage furniture, toys to manipulate, or part of aggression displays.

Chris Pyle, Johns Hopkins School of Medicine:
Since our baboons are in single cages, and not grouped or free ranging, our environment differs from most in this discussion. We were experimentally confined by our research procedures. Since we were recording minute-by-minute interaction data, we modified the wooden “logs” – the logs weren't just tree branches, but more along the line of wooden “devices”, made from cherry wood branch sections (from my backyard), that were seasoned for a year after being cut.

Because our general research is on the study of audition, it was necessary to put our “enrichment” animals into another research area since they created so much noise with the logs, raking them across bars. Due to this tendency of our baboons to make noise with whatever object is in their cage, we cannot use logs as general enrichment devices. I do however, believe that wooden branch material is well received by baboons and, when experimental procedures allow, that they can be used for enrichment. We now leave the “logs” in the cages that we put animals into while their home cages are being sterilized. This “play” cage is equipped with several enrichment devices – log, kong toy, chain.

In our original study of short-term use of wooden logs, the animals showed much greater interest in the logs over the kong and the swing toys (Hienz et al., 1998, this Newsletter, 37[3], 6-10).

The animals rolled the log, picked at it, raked it over the bars, and clutched it. We had no health or sewer problems, but animals at times rolled the logs over fecal matter or urinated over the logs. We would remove the logs once weekly to read the recording devices hidden within them, and we “cleaned” the logs off, but did not sanitize them. Each log would thus be personalized with an animal's scent, and be thrown out at the end of the study.

We studied the question of animals losing interest in logs over a long period in our second paper (Hienz et al., 2000, this Newsletter, 39[2], 1-3). Interestingly enough, some animals became disinterested while others became more and more interested over extended periods of time. As with all our other findings with enrichment devices, interest frequently waxes and wanes with individual animals. I think that a fresh log, given once a month or once every two months, would be a good device to use for large primates that are individually housed. Interest in the logs, of course, began immediately with the removal of the bark, and frequently declined afterwards. Due to this “false positive” beginning, we removed the bark prior to our experiments, but in a general lab setting, I think the animals find a lot of gratification in removing the bark.

And Viktor added: It seems that there is a general con-sensus that wooden objects provide *inexpensive, *safe, *long-term and *effective stimulation for the expression of non-injurious, species-typical behaviors such as perching, gnawing, gouging, manipulating and playing. It is my understanding that routine use of wooden objects is no obstacle to AAALAC International accreditation. Using common sense for the cleaning and replacing of wooden material, as needed, is certainly a prerequisite.

Figure 1: Bobby, the rhesus monkey, with branch segment.

Material of the following trees may be “chewy” for the animals but the critters manage to tear off long strips of bark and wood. Inevitably, this clogs drains in an animal room if many monkeys are simultaneously engrossed in shredding branch material, particularly when it is fresh. If this is a problem in your facility, don't use the following tree species for your enrichment program: *box elder (Acer negundo), *silver maple (Acer saccharinum), *black cherry (Prunus serotina), *white oak (Quercus alba), *black locust (Robinia pseudoaccacia), *white elm (Ulmus americana), *weeping willow (Salix babylonica), and other species which disintegrate into strips.

Red oak (Quercus rubra) branches – cut from dead and relatively dry trees – are not shredded when gnawed, but gradually wear into flakes of bark and wood, so small that even large quantities pass through drains. See <>). The study by Line & Morgan (Laboratory Animal Science, 1991, 41, 365-369) suggests that almond tree wood is equally suitable.

When I attempted to install branch-perches in more than 700 cages, I soon ran out of material. Before capitulating, however, I conducted a choice experiment (see this Newsletter, 1990, 29[1], 13-14) which, to my surprise, made it clear that rhesus macaques spend an equal amount of time on a branch – in one section of the double cage – and on a PVC pipe (same diameter; in the other section of the double cage). Obviously the animals showed no preference for branches. This made it very easy for me: all cages were equipped with PVC perches within less than a month.

Female Reproductive Advertisement and Social Factors Affecting the Sexual Behavior of Captive Spider Monkeys

Rosalía Pastor-Nieto
University of Warwick


The transmission of messages about the reproductive condition of females is extremely widespread among mammals. Female urogenital signals, particularly those arising during estrus, play the most important role in the chemical signaling of many primate species. Genital scent-marking behavior by females, sniffing and mouthing of female genitalia by males, and even tasting of female urine and vaginal discharges are preludes to sexual arousal by male primates (Epple et al., 1993). As with other chemical signals, female urogenital signals derive from many sources. Besides urine there are specific secretions of the reproductive tract and the accessory sex organs which may be modified by the action of microorganisms inhabiting the vagina. Many species also possess well developed skin glands in the anogenital region (e.g., labial gland, circumgenital glands) which further contribute to the chemical ambience of the genital region of female primates. Five chemical signaling materials have been identified in the female: (1) Urine components. (2) Materials from the upper reproductive tract, such as oviducal, endometrial, and cervical mucus. There are cyclic changes in the cervical lipids (hydrocarbons, glycerides, cholesteryl esters, free fatty acids and phospholipids [Singh et al., 1972]). (3) Materials from the vaginal walls. The vagina is rich in glands and receives exfoliated cells from its surface and transudates of blood plasma. It is also rich in glucose that is transformed into glycogen by enzymes which are stimulated by high estrogen levels (Singh et al, 1972). (4) Secretions of the vulval glands (also called Bartholin's glands). The functions of these secretions are unknown. (5) Materials from the activity of resident vaginal microflora. In human females, lactobacilli and facultative and strict anaerobes have been identified in the vaginal tract. These bacteria are known to use glycogen as a substrate, producing a wide variety of volatile fatty acids such as acetic acid. In the rhesus monkey, acetic and isovaleric acids are known to dominate female vaginal odor (Michael et al., 1972; Larsen et al., 1977).

The effects of vaginal secretions as monitored by male Macaca mulatta were first studied by Michael & Keverne (1968). In platyrrhines, anogenital inspection by males has been described in the dusky titi (Callicebus moloch, Moynihan, 1966), the night monkey (Aotus trivirgatus, Moynihan, 1976), spider monkeys (Ateles geoffroyi and A. belzebuth, Klein, 1971; Eisenberg & Kuehn, 1990; Chapman & Chapman, 1990) and the woolly spider monkey (Brachyteles arachnoides, Milton, 1985).

Figure 1: External genitalia of female Ateles geoffroyi illustrating the a) glans clitoridis, b) anus and c) sulcus retroglandis adapted from Hill (1963)

The clitoris of the female spider monkey has been a subject of curiosity due to its enormous length (Figure 1; Hill, 1963). This structure is a soft flabby structure more or less resembling the penis but longer (4.7 cm in Ateles belzebuth). Hill (1963) made a detailed description of the clitoris, emphasising its sulcus retroglandis and the pigmented horseshoe-shaped glans clitoridis located at its caudal tip. No studies have been able to explain the evolutionary mechanisms that have favored such a large clitoris in female spider monkeys. Some authors suggest that, because the frugivorous genus Ateles tends to forage individually, females use small quantities of urine retained in the perineal groove (sulcus retroglandis) of the clitoris to leave scent traces in the trees to advertise their reproductive condition (Klein, 1971). Milton (1985) suggests that females travel more when receptive, depositing urine in various places. There is a lack of information concerning the vaginal components that could serve as pheromones in spider monkeys. Hodges et al. (1981) identified estriol, estradiol, and estrone in female spider monkey urine, with estrone in the highest concentrations.

No studies have been carried out to evaluate the influence of familiarity upon the reproductive performance of spider monkeys in captivity, although they are a very common species of primate in Mexican zoos. Also, the effect of length of the external genitalia of females has not yet been evaluated in the sociosexual context.


The aims of this paper are to evaluate (1) the role of olfactory inspection (clitoris grasping and sipping urine) of female spider monkey external genitalia as precopulatory sexual behavior by the adult male; (2) the effect of clitoris size upon female sexual attractiveness; and (3) the effect of familiarity between group members on the occurrence of sexual behavior.

Because of the small male sample size (N=2 males), comparisons of male behavior were not possible; therefore, statistical differences were only evaluated among females (as receivers of male sexual behavior).

Materials and Methods

Subjects: Observational data were collected for 15 months from two groups of nine captive black-handed spider monkeys (Ateles geoffroyi; N = 18) housed at the Centenario Zoo at Mérida, Yucatán, Mexico. The study subjects belong to the subspecies A. g. yucatanensis (Dubach, personal communication). Spider monkeys of this species are found in forest patches and in protected rain forest natural reserves of the Yucatan Peninsula.

The two groups studied have different histories. One was a newly formed group, composed of nine wild-caught, unrelated animals of various ages which had been kept as pets since infancy. They had been confiscated by wildlife officials and given to the Zoo. They were kept in individual quarantine before being incorporated into a group. This study began five months later.

The other group studied was an established group, composed of nine captive-born animals that are currently breeding. Unfortunately, there are no records on how long the animals have been together, birth dates, or general reproductive profiles. Paternity tests were performed by the Department of Genetics of the Chicago Zoological Society to determine the group's kinship.

Each group was composed of seven females, one adult male, and one juvenile male. This coincidental similarity between the two groups made it possible to control for group composition.

Because birth dates were not known, age was determined by correlating individuals' eye skin pigmentation (ESP) with age categories. The skin that surrounds the eyes lacks pigmentation in newborns and infants (Eisenberg, 1976). According to Eisenberg, this lack of pigmentation persists until over 14 months of age in Ateles geoffroyi. As the juvenile matures, the face gradually becomes pigmented, except for the skin around the eyes, which can still be pink at 19 months of age. Further development sees the accumulation of more melanin in the dermis and epidermis of the skin surrounding the eyes, forming more and more dark brown freckles.

Each animal was assigned to an age class based on this criterion. Using ESP as a method to approximate age has several possibilities for error including individual variation, size range of age categories, and observational error. However, in the absence of birth records, this indirect measure of approximate age was useful.

Subject environment: During this study the monkeys were housed in basic, temporary accommodations away from the public. Animals from the established group were housed together and never mixed with unfamiliar animals.

Housing: The two groups of black-handed spider monkeys lived in two neighboring enclosures (each 34.8 m2 – or 4.35 m2 per animal), separated by wire mesh. These enclosures are furnished throughout with ropes and tree trunks that enable the monkeys to move in a three-dimensional environment. The sand floors of the cages are renewed every 3-6 months and perches and walls are disinfected every month. Due to the tropical climate of the Yucatan Peninsula, which has an average temperature of 25°C, the animals do not require night enclosures. If isolation of an animal is required, the feeding section is adapted to this purpose. The cages are provided with shelters just above the main perch, where the monkeys normally cluster together hiding from the rain.

Husbandry: As mentioned above, feeding takes place in a special section of the enclosures. This 5 m2 feeding section has a cement floor, over which the keepers disperse fruit. This cement floor is routinely washed prior to feeding. Water is provided here in a bowl.

Food is provided twice a day and consists of a variety of fruits and vegetables (bananas, oranges, papaya, watermelon, carrots, tomatoes, lettuce). Twice a week the animals are provided with freshly cut Brosimum alicastrum, a natural food resource for Ateles in Yucatan. In the evening, commercial dog food or cooked rice or oats is supplied, sometimes with honey or milk and vitamins added. Pregnant and lactating females are supplied with vitamin and mineral supplements; and, as a preventive measure, all monkeys are dewormed every six months with Albendazol (Zentel).

Methods of behavioral sampling: Four sampling methods were utilized: focal animal sampling, scan sampling, ad libitum sampling, and continuous sampling (Altmann, 1974). Focal samples were used for adult females and males. This enabled us to quantify social relationships and compute frequencies of behavior (Dunbar, 1975). The daily data for each individual was collected randomly to avoid bias.

Sexual behavior was recorded using focal and ad libitum sampling. Animals were followed for 30 focal minutes. When a male was observed inspecting females' genitals and/or animals were observed attempting copulation (leg lock or female sitting on male's lap), I left the focal subject and changed to ad libitum continuous sampling, to record as many instances of sexual behavior as possible.

Behaviors sampled: The sexual behaviors recorded were defined as follows:
a) Inspecting behaviors
Male approaches female, manipulates her clitoris, squeezes the glans clitoridis, and smells his hand.
sip: Male sips the urine of a female shortly after she has urinated.
b) Copulatory behaviors
lap sit:
Receptive female approaches male and initiates mounting by sitting on the male's lap.
leg lock: Male places his hind legs over the female's thighs. Usually both animals are sitting down.
thrust: Intromission.

Because the animals were inactive during the middle of the day when temperatures were highest, sampling was restricted to the periods between 08:00-12:00 and 16:00-17:00, when the animals were most active.

A total of 208 hours of focal observations were taken from the newly formed group and 242 hours from the established group. Four instances of complete copulation and one copulation attempt by a male were recorded through ad libitum sampling in the established group. No complete or incomplete copulation was recorded in the newly formed group.

Two males were not included in the focal samples (Bart and Marcos). Marcos was a juvenile and Bart an infant when I started this study. Their participation in the social network was very limited, and they spent most of the time playing. Bart was still very dependent on his mother and clinging to her at the time I started to collect the focal samples.

Evaluating the relationship between genital grasping as a form of genital inspection and copulation: Frequencies (events/min) of males actively grasping the external genitals of females and mounting were correlated using Spearman Rank coefficients.

Evaluating the relationship between clitoris size, age, and female sexual attractiveness: While the animals were anesthetized for blood collection (for DNA fingerprinting), they were weighed and measured and female clitoris lengths were obtained.

To test for the relationship between clitoris size and sexual attractiveness (measured by the number of times the males grasped females' genitals and/or sipped females' urine), the residual of clitoris length, regressed on body weight, was correlated with ESP and frequency with which males performed these behaviors. The purpose of using these residuals was to control for body weight (body weight in kg regressed against clitoris length in cm).

In the newly-formed group, Doris was excluded from the sample, as her clitoris size seemed to differ greatly from the Ateles geoffroyi average length reported in the literature (4.7 cm). Doris's clitoris was smaller than those of the rest of the females; we thought she belonged to another species of Ateles. However, the karyotype profiles revealed that Doris, like the rest of the animals studied, belongs to Ateles geoffroyi yucatanensis (Dubach, personal communication). The reason for the small size of her clitoris remains unknown.


a) Inspection and sexual behavior: In this study, only the adult male from the established group (Loco) actively manipulated the clitorises of females. This behavior was also accompanied by sniffing his hand after the manipulation. Figure 2 shows two peaks of clitoris inspection by Loco in a period of 14 months. These peaks coincided with incidents of mounting, in April and in August, suggesting that female genital inspection by males precedes copulation. Loco also sipped the urine of females. Damian, the adult male in the new group, neither grasped the clitoris of females nor copulated with them, but he did sip the urine of one female (Vicky) shortly after she deposited urine. I included this form of genital inspection when correlating age with sexual performance, as pheromones from the sulcus retroglandis can be flushed out with urine.

Figure 2: Female genital manipulation and mounting by Loco (Established group).

This difference in grasping by males between the two groups (Mann-Whitney-U Test, Z=-2.44, 2-tailed p= 0.01, N=13) suggests that the social environment might have an important effect upon females' sexual attractiveness. Another possible reason for this is that there may be differences in sexual interest between the males, and elusive behavior by females, as adapting to the entirely new social context could have been very stressful for the animals of the newly formed group.

Table 1: Variables utilized to evaluate female sexual attractiveness. * 0= not pigmented, 1= partially pigmented, 2= pigmented

The clitorises of three females in the established group (Guera, Emma, and China) were almost always grasped preceding copulation. Another female, Flaca, gave birth in August, 1995. Prior to the birth of her infant, Loco (the adult male) was seen grasping her genitals on two occasions; once in January, eight months prior to delivery, and once in April. Considering that the gestation period of Ateles is 226 days (Robinson & Janson, 1987), an unobserved copulation must have taken place sometime at the end of January of that same year. This suggests that her genitals were also grasped close to when copulation took place.

Another female worth commenting on is Faby. Loco grasped her clitoris at a very high rate. Two frequency peaks of grasping were observed, in April and in July, the periods when Loco copulated with the other females. But even though Loco grasped her genitals frequently, he was never seen attempting to copulate with her.

Lisa and Lucrecia, who had not reached sexual maturity when this study was carried out, were never observed being inspected or mounted by Loco.

b) Clitoris size, age category (ESP) And female attractiveness: To evaluate the relationships between: (1) age and clitoris size, (2) age and frequency with which females are inspected by males, and (3) clitoris size and genital grasping, the residuals of the regression between clitoris length and body weight, and absolute clitoris length were correlated with ESP and frequency of clitoris grasping by a male (see Table 1).

Age and clitoris size: The results suggest that age category of the females, based upon eye skin pigmentation, is not significantly correlated to clitoris length/body weight residual (rs=.06, p=0.84, N=13). Absolute clitoris size was also not significantly correlated with frequency of genital inspection (rs= -.04, p=0.89, N=13). These results suggest that clitoris size is not a function of female age.

Age and genital inspection: For the male of the established group there was a non-significant relationship between total frequency (events/minute) of both sipping and grasping and age of females (ESP) (rs=1.65, 2-tailed p=0.61), and a non-significant relationship between just frequency of sipping and age (rs=0.49, 2-tailed p= 0.61). However, there was a significant relationship between frequency of grasping and age (rs=1.94, 2-tailed p=0.04). Presumably Loco is obtaining chemical signals related to the reproductive condition of adult females through this grasping. Damian showed a non-significant relationship between frequency of sipping and age, (rs=0.49, 2-tailed p= 0.04),suggesting that he is not obtaining chemical information on her reproductive condition.

Clitoris size and genital inspection: Neither clitoris length/body weight residual nor absolute clitoris length was significantly correlated with genital inspection (clitoris length/body weight residual with genital inspection: rs=.-10, p=0.72, N=13, absolute clitoris length and genital inspection: rs= -.22, p=0.46, N=13).


The females of the established group were inspected more by a male than the females of the newly-formed group. One of the reasons for this is that the females of the established group seemed to be advertising their reproductive cycles, and therefore to be more attractive to the male. Older females were inspected more than younger females, suggesting that the difference in clitoris grasping by the male is a function of the females' age. Also, the results obtained seem to suggest that an increase in frequency of female genital grasping by the male precedes copulation.

The differences between groups, in males actively grasping the genitals of females, could be explained by the fact that it was stressful for the animals of the recently convened group to be in a new situation, surrounded by unfamiliar animals, in their own and the established group. It might be that the adult females of the newly formed group were reproductively suppressed due to that social stress, and therefore were not advertising reproductive cycles (Dunbar, 1980).

Another possible explanation is that learning might be a factor for the development of pre-copulatory behaviors in male spider monkeys. In wild conditions sub-adults join all-male bands (MacFarland 1990), and probably learn how to approach and inspect females as they wander within their natal group's range. In this study the male of the newly formed group, Damian, approached a certain female, probably attracted by her scent. He then indirectly inspected this female by sipping the urine she had deposited. The lack of familiarity among the members of this group may explain why Damian was reluctant to directly inspect the genitals of females. It is also possible that, at the same time, the females were reluctant to be directly inspected by a relatively unfamiliar conspecific.

Because clitoris size did not seem to be related to female sexual attractiveness, the function of such a large structure remains unknown.

Report from the Nairobi CITES Conference, April 10-20, 2000

Shirley McGreal
International Primate Protection League

Two issues of relevance to primates were raised at the Convention on International Trade in Endangered Species (CITES) conference held in Nairobi from April 10-20, 2000. IPPL was represented at this meeting by Shirley McGreal and Dianne Taylor-Snow. IPPL also sponsored the attendance of representatives of the Indonesian non-governmental organization (NGO), KSBK (Animal Conservation for Life).

Document 11.45.1, proposed by Switzerland, Germany, and the United Kingdom, was headed “Concerning diagnostic samples, samples for identification, research and taxonomic purposes, and cell cultures and serum for biomedical research.” The proposers contended that issuance of CITES documents for transporting cell cultures and serum, even for commercial purposes, is a burden and “an impediment to research and legitimate trade.”

Many national delegations and NGOs raised questions about the draft resolution. Mexico and several other nations objected on the grounds that genetic materials could be patented and used for commercial purposes. IPPL raised questions about the potential harm that could be caused by efforts to obtain serum from free-living primates since it would be impossible for national authorities to monitor the ground operations of capture/release teams, possibly resulting in injuries or fatalities to the CITES-protected primates, as well as a potential for captors to infect free-living animals.

Zoo associations supported the resolution as they want to be able to identify species and diagnose illness in animals living overseas. Law enforcement agencies want to be able to move samples rapidly for identification. Because there was insufficient support for the resolution to pass, due to the broadness of the exemptions, the proposal was referred to an inter-session working group. It is likely that a more restrictive resolution will be proposed at the next Conference of the Parties, to be held in two and one-half years.

The “bushmeat problem,” the trade in the meat of protected animals, which has increased in recent years, was addressed. Several meetings on the subject were held, attended by government representatives and observers. Only a small proportion of the bushmeat trade is intercontinental in scope but there is cross-border regional trade in Africa. The basis of discussions was a British document (Document 11.44). A working group was formed which will initially concentrate on the Central African nations. A first meeting may be held as early as this summer. The U.K. offered to provide funds. African delegates expressed their concern at the situation. Delegates from several nations which are torn apart by civil strife reported that they had the will, but lacked the ability, funds, and staff, to address the problem.

African CITES-protected primate species involved in the bushmeat trade listed on Document 11.4 are: *Appendix I (the most restrictive category): Diana guenon, gorilla, drill, mandrill, bonobo, and chimpanzee. *Appendix II: moustached monkey, red bellied guenon, red-eared guenon, owl-faced monkey, De Brazza's monkey, greater white-nosed monkey, crowned guenon, Preuss' guenon, Sclater's guenon, sun-tailed guenon, black colobus, king colobus, and grey-cheeked mangabey.

Recognition and Alleviation of Pain and Distress in Laboratory Animals

American Association for Laboratory Animal Science (AALAS)


The Animal Welfare Act mandates that Institutional Animal Care and Use Committees (IACUCs) oversee the care and use of animals covered by the Act. IACUCs are composed of scientists, veterinarians, and at least one public member. They must assess warm-blooded animal research protocols to determine if (1) proposed animal use is essential for achieving relevant scientific goals, (2) the appropriate species have been selected, (3) the number of animals requested is properly justified, (4) the care of animals is appropriate, (5) provision for alleviating pain or distress is appropriate, and (6) alternatives to studies that might cause pain or distress have been sought. The Public Health Service (PHS) Policy on Humane Care and Use of Laboratory Animals (which implements the Health Research Extension Act of 1985 and the U.S. Government Principles for the Utilization and Care of Vertebrate Animals used in Testing, Research, and Training) adopts a similar position that is applicable to all vertebrate animal research protocols.

The Animal Welfare Act is administered by the U.S. Department of Agriculture (USDA), while the PHS Policy is administered and coordinated by the Office of Laboratory Animal Welfare (formerly the Office for Protection from Research Risks). These agencies; the laws and policies they administer; highly respected voluntary programs, such as the Association for Assessment and Accreditation of Laboratory Animal Care (AAALAC) International; and local IACUCs provide effective, comprehensive assessment and monitoring to assure humane animal care and use.

A significant provision of the Animal Welfare Act requires that institutions provide an annual report indicating the number of covered species used in the following categories:
Category C – animals in which procedures caused no pain or distress;
Category D – animals in which pain and distress during procedures was appropriately relieved by pain- or distress-relieving drugs;
Category E – animals involved in procedures which cause pain or distress that was not relieved by drugs for scientific reasons.

Animal use reported in Category E must be accompanied by an explanation and justification as to why drugs to relieve pain and distress were withheld. This information is readily accessible to the public through the Freedom of Information Act.

The current USDA reporting categories have been in use for many years and would benefit from revision and expansion to improve their utility. Many IACUCs have recognized that the USDA system is outdated and have developed categories pertaining to the extent of pain and distress that are more accurate and informative. The USDA is currently reviewing policy pertaining to the annual report, which is a welcome initiative. However, it appears that potential revisions may not address the major limitation of the current categories: inadequate discrimination regarding the intensity or duration of pain or distress. In fact, they may further reduce the accuracy of reporting by increasing assignment to Category E of animals that experience mild or questionable pain or distress. It will be unfortunate if the policy revision misses the opportunity to improve reporting categories.


The evaluation of potential pain or distress is complex because thresholds and manifestations of pain and distress vary among species and among individuals within a species.

The determination of what constitutes pain or distress in animals is further complicated by the fact that there are no universally agreed-upon criteria for assessing or determining what is, or is not, painful or distressful to an animal.
*The alleviation of pain and distress is often a diverse task that may require drugs, adjustments to environmental enrichment, modifications in research protocols, and other appropriate and humane strategies.
*Pain and distress, and the methods used to alleviate them, may interfere with research results.
*The USDA's categories for reporting pain and distress and measures to alleviate them are not optimally informative and potential policy changes may make them even less so.


*Laboratory animal veterinarians and other animal caregivers have a legal and moral obligation to alleviate pain and distress in laboratory animals.
*The complex nature of modern animal experimentation implies the need to report animal use accurately. Therefore, current USDA categories should be revised and expanded to facilitate more precise and informative reporting. Furthermore, annual reporting of animal use should be the responsibility of the IACUC in conjunction with assessment and monitoring by a qualified veterinarian.
*Alternatives to animal use in biomedical research should be sought. However, once a request to use animals has been made and approved, experiments should be performed as humanely as possible and with as few animals as possible.
*IACUCs must ensure that all personnel involved in the care and use of animals are adequately trained. Training should include concepts and methods to recognize pain and distress in laboratory animals and to alleviate them or seek assistance in doing so. This process will raise staff awareness regarding humane treatment and will improve the quality and documentation of monitoring.
*Qualified veterinarians should be involved in the design, monitoring and documentation of experiments that have the potential to cause more than momentary pain and distress to laboratory animals. The anticipated pain or distress level should be categorized and assigned during IACUC protocol review and monitored prospectively. The assignment should be reviewed at appropriate intervals and changes may be recommended after additional observation and prior to submission of the USDA Annual Report.
*Conditioning and monitoring of research animals should be designed prospectively. The corresponding schedules should indicate the frequency of observation and responsibilities of monitoring and laboratory personnel. In addition, correct doses of appropriate anesthetics, analgesics and tranquilizers should be selected preemptively by the principal investigator in consultation with the veterinarian. Possible outcomes (endpoints) should be discussed among the veterinarian, the investigator, and other laboratory personnel listed in a given protocol.
*Potentially painful or distressful procedures should be closely monitored by the animal health care staff and appropriate treatment instituted. New or novel procedures that may be painful should initially be performed under veterinary surveillance or supervision. Analgesics should be administered preemptively for known potentially painful procedures.
*Death should be avoided as an endpoint for animal experiments. Alternatives such as behavioral changes, fluctuations in body temperature, body condition, and weight-loss patterns should be sought and implemented.
*More research is needed on the assessment and alleviation of pain and distress to optimize the humane treatment of laboratory animals. The scientific and moral priorities inherent to animal research emphasize why such research is essential.

Travelers' Health Notes

Imported Dengue – United States, 1997 and 1998

Dengue is a mosquito-transmitted acute viral disease caused by one of four dengue virus serotypes. Dengue is endemic in most tropical areas of the world and has occurred in U.S. residents returning from travel to such areas. This report summarizes information about imported dengue cases among U.S. residents for 1997 and 1998, which indicates that most persons with a known travel history probably acquired infection in the Caribbean islands or Asia.

Serum samples from 349 persons who had suspected dengue based on clinical presentation and onset of symptoms in 1997 and 1998 were submitted to the Centers for Disease Control and Prevention (CDC). From these samples, 38% were laboratory diagnosed as dengue. Dengue diagnosis was negative in 37% and indeterminate in 22% because convalescent samples for serologic testing were unavailable.

Travel histories within the two weeks before illness, available for 122 persons, indicated that infections probably were acquired in the Caribbean islands (61 cases), Asia (30), Central America (23), South America (four), Africa (three), and the Pacific islands (one). In 1998, 90 laboratory-diagnosed cases were reported, a 70% increase from the 53 cases reported in 1997.

Commonly reported symptoms were fever (94%), headache (69%), myalgia (53%), rash (53%), arthralgia (32%), retro-orbital pain (27%), nausea or vomiting (25%), chills (24%), diarrhea (19%), and petechiae or ecchymoses (15%). At least seven patients were hospitalized, and one patient died.

The principal vector of dengue is the mosquito Aedes aegypti, which has a wide distribution in most tropical and subtropical areas. In the United States, Ae. aegypti can be found during summer months in many states. Most U.S. residents with dengue become infected during travel to tropical areas, although local transmission of dengue was documented in Texas in 1999.

The incubation period of dengue is 4-7 days (range: 3-14 days). Dengue virus infection can be asymptomatic or cause illnesses ranging from mild undifferentiated fever to severe disease, including hemorrhage and shock. Persons traveling to areas where dengue is endemic should avoid exposure to mosquitoes by using repellents, wearing protective clothing, and remaining in well-screened or air-conditioned areas. No vaccine is available for preventing dengue infection. The Ae. aegypti mosquito is well adapted to urban environments and can be found in or near human dwellings, where it can be found in closets, bathrooms, behind curtains, and under beds. The species usually bites during the early morning and late afternoon, but may feed at any time during the day when indoors or during overcast periods.

With an increase in traveling to and from endemic areas, more cases of imported dengue may be expected and health-care providers should consider dengue in the differential diagnosis of illness for all patients who have fever and a history of travel to tropical areas within two weeks before the onset of symptoms. Supportive measures should be given, and only acetaminophen is recommended for management of pain and fever. Aspirin and other nonsteroidal anti-inflammatory agents are contraindicated because of their anticoagulant properties. Acute-phase and convalescent-phase serum samples should be obtained for viral isolation and diagnosis and sent for confirmation through state or territorial health departments to CDC's Dengue Branch, Division of Vector-Borne Infectious Diseases, National Center for Infectious Diseases, 2 Calle Casia, San Juan, PR 00921-3200 [787-766-5181; fax: 787-766-6596]. Serum samples should be accompanied by a summary of clinical and epidemiologic information, including date of onset of disease, date of collection of sample, and a detailed recent travel history. – From Morbidity and Mortality Weekly Report, 2000, 49, 248-253

Yellow Fever from Venezuela, 1999

On September 28, 1999, a previously healthy 48-year-old man from California sought care at a local emergency department and was hospitalized with a two-day history of fever (102º F), chills, headache, photophobia, diffuse myalgias, joint pains, nausea, vomiting, constipation, upper abdominal discomfort, and general weakness. On September 26, he had returned from a 10-day trip to Venezuela. On September 29, his illness was reported to the California Department of Health Services (CDHS) as a suspected case of viral hemorrhagic fever.

On admission to the hospital, physical examination revealed icteric sclerae and tenderness in the upper abdomen. Multiple red papular lesions with excoriations consistent with recent mosquito bites were seen on his lower legs and feet. No hepatosplenomegaly or lymphadenopathy was noted. Laboratory results indicated markedly elevated serum bilirubin and liver enzymes, leukopenia, thrombocytopenia, and evidence of acute renal failure.

A preliminary diagnosis of hemorrhagic fever syndrome was made, and the patient was placed on doxycycline and ceftriaxone. Cultures of blood and urine were negative for bacterial pathogens. Blood smears for malaria were negative. On October 1, the patient developed general seizures and upper respiratory obstruction. He was placed on mechanical ventilation and transferred to the intensive care unit. His condition deteriorated rapidly, with severe coagulopathy and cardiac arrhythmias. He died on October 4.

On October 7, an autopsy was performed; YF viral antigens and YF virus-specific nucleic acids were found. Other tests were negative for dengue virus, leptospira, New World arenaviruses, spotted fever group rickettsiae, and hantavirus. The patient's serum was tested; no antibody to YF virus (17D) was detected in serum drawn September 28, but an IgG titer of 1:128 and an IgM titer of >1:80 were detected in serum drawn October 1.

During September 16-25, the patient had traveled with six companions to rainforests in southern Venezuela (Amazonas State). He experienced multiple mosquito bites during his visit despite using DEET-based repellents. Before his trip, the patient had received tetanus toxoid, typhoid vaccine, hepatitis A vaccine, and malaria prophylaxis, but not YF vaccine. The travel companions were contacted by the California Department of Health Services about their health and vaccination status; none had become ill during or following the trip. Five had received YF vaccine before travel. The unvaccinated traveler's serum was negative for YF virus antibody.

This was the second case of imported fatal YF in a U.S. resident returning from South America since 1996. Neither patient had received YF vaccine before travel. In 1996, a Tennessee resident returned from a 9-day trip to Brazil with fever, headache, and myalgias. He died 10 days after onset of symptoms, and YF virus was identified from tissue culture.

YF occurs in at least seven tropical South American countries (Bolivia, Brazil, Colombia, Ecuador, French Guiana, Peru, and Venezuela) and much of sub-Saharan Africa. The sylvatic cycle involves nonhuman primates and mosquitoes that breed in tree holes. Persons living or working in proximity to such jungle or forest habitats who are bitten by infected mosquitoes can develop “jungle YF.” Another cycle exists between humans and Aedes aegypti mosquitoes. Ae. aegypti mosquitoes are present in most urban centers of South and Central America, the Caribbean, and parts of the southern United States; persons in these areas are at risk for urban YF infection. YF has not been reported from India or other parts of Asia despite the presence of Ae. aegypti.

World Health Organization (WHO) data suggest that YF transmission is increasing. WHO estimates that approximately 200,000 YF cases occur each year, most in sub-Saharan Africa. Along with increased YF transmission, the number of travelers from the United States to South America and Africa has more than doubled since 1988. These travelers may be at risk for YF unless precautions are taken, including receipt of YF vaccine.

YF is one of three diseases (the others are plague and cholera) subject to international quarantine regulations. CDC is required to notify WHO of all YF cases in the United States within 24 hours. Accordingly, all suspected and confirmed cases should be reported immediately through local and state health departments to CDC's National Center for Infectious Diseases, Division of Quarantine [404-639-8100]; acute and convalescent-phase serum should be collected and sent for viral isolation and diagnosis to CDC's National Center for Infectious Diseases, Division of Vector-borne Infectious Diseases [970-221-6400]. The location of certified U.S. YF vaccination centers is available from local and state health departments. If YF vaccine is medically contraindicated, health-care providers should supply persons with a letter listing reasons for not vaccinating, and persons should carry this with them when traveling. Details of vaccine recommendations and requirements of individual countries are available from <>.

CDC recommends YF vaccination for travelers to countries reporting YF. Vaccination also is recommended for travel outside urban areas of countries that officially do not report the disease but are in the YF-enzootic zone. Travelers should also take protective measures to reduce contact with mosquitoes; these include wearing clothes that cover most of the body, staying in well-screened areas, using insect repellent (containing DEET at a concentration of <35%) on exposed skin and clothing, and sleeping under bed nets treated with permethrin or deltamethrin insecticides. – From Morbidity and Mortality Weekly Report, 2000, 49, 303-305

News Briefs

Sherry Washburn Dies at 88

Dr. Sherwood Larned Washburn, an anthropologist and pioneering primatologist who linked the evolution of human behavior traits to the actions of apes and monkeys, died on Sunday at a hospital near his home in Berkeley, California. Sherry was an emeritus professor of anthropology at the University of California at Berkeley, where he taught and worked from 1958 to 1978. He helped the University become a leader in primatology during his tenure, with his study of baboon colonies in Kenya.

His work also took him to remote areas of Sri Lanka, Thailand, Borneo, and South Africa. On campus, Washburn's lectures inspired standing ovations from his students. His books included Human Evolution: Biosocial Perspectives and Ape Into Human: A Study of Human Evolution. The Fourth International Congress of Primatology in 1972 was dedicated to him. – From the New York Times, posted to Primate-Science, April 19

Nim, Sign Language Chimp, Dies at Age 26

The Fund for Animals announced the passing of Nim, who died of heart failure on March 10 at the Fund's Black Beauty Ranch in Murchison, Texas. He was 26 years old. Nim was the subject of the book Nim: A Chimpanzee Who Learned Sign Language, by Herbert S. Terrace. – Posted to AlloPrimate, March 10, 2000

Michael Gorilla Dies

One of just two gorillas in the world who are said by handlers to have learned human language has died. The lowland gorilla known as Michael was 27 and, according to his handlers, knew about 500 gestures in American Sign Language at the time of his death on April 19, at the Gorilla Foundation's preserve 25 miles south of San Francisco. “He had a great facility with gestural communication and was a talented artist. His work has been displayed in galleries around the country,” said Francine Patterson, the Foundation's president. Michael came to the foundation in 1976 at the age of 3½ years.

Although gorillas are prone to heart disease, it is unclear what killed Michael, and an autopsy will be performed, said Gillian Ladd, an assistant to Patterson. Gorillas can live into their 50s. – From the Associated Press, posted to Primate-Science April 20, 2000

Nikko Says, “Don't Feed the Monkeys”

The central Japanese tourist town of Nikko is fed up with monkey-feeding tourists. “Don't feed the monkeys,” warns a first-of-its-kind ordinance submitted to Nikko's assembly Monday. Troops of wild macaques are among the area's best-known attractions, along with a 318-foot waterfall and a shrine that is the burial place of the 16th century shogun who unified Japan. The Toshogu shrine features three of the world's famous monkeys: statues of the see-no-evil, hear-no-evil, speak-no-evil trio.

But Nikko's real-life simians are causing their share of evil – damaging property and occasionally biting people while scavenging for food. Government officials blame doting tourists for teaching the monkeys to accept handouts. Every year, 30 to 40 people are hospitalized with bites, he said.

In November, officials abandoned a campaign to jolt aggressive macaques with electrified prods after residents criticized the tactic as cruel. So Nikko decided to teach humans a lesson instead. The ordinance is expected to pass during the assembly session ending this month. It carries no penalty except allowing names of deliberate offenders to be published, although officials acknowledged they are uncertain how much that will discourage tourists. – From an Associated Press article by Gary Schaefer, posted to Alloprimate, March 6, 2000

Office Status for Division of Animal Welfare

The Office for Protection from Research Risks' (OPRR) Division of Animal Welfare has now been officially named the Office of Laboratory Animal Welfare (OLAW) by the National Institutes of Health. Nelson Garnett is the Director of OLAW, reporting to Wendy Baldwin, Deputy Director of NIH for extramural research. OLAW will continue to be responsible for all of the animal-related functions of the OPRR, including implementing and interpreting the Public Health Service (PHS) Policy on Humane Care and Use of Laboratory Animals, administering an educational program for PHS-supported institutions and investigators, negotiating Animal Welfare Assurances, and evaluating compliance with the PHS Policy. OLAW will remain at NIH when OPPR moves to the Office of the Secretary of the Department of Health and Human Services. OLAW has a Web site at <>.

New Monkey Species Discovered

Two new species of marmoset were found by Marc Von Roosmalen in a remote corner of Brazil's Amazon rain forest, about 190 miles from Manaus, where local residents kept them as pets. One of the new monkeys is the Callithrix manicorensis, or Manicore marmoset. It has a silvery white upper body, a light gray cap on its head, yellow to orange underparts and a black tail. The other, Callithrix acariensis, or Acari marmoset, has a snowy white upper body and underparts, a gray back with a stripe running to the knee and a black tail with a bright orange tip. An average adult of both species measures nine inches with a 15-inch tail, and weighs around 12 ounces. The monkeys are named after the Manicore and Acari rivers – tributaries of the Amazon. The discovery was reported by Conservation International.

Roosmalen, a Dutch primatologist at Brazil's Amazon National Research Institute, says he has found 17 more monkeys he believes are new to science, as well as five new birds and two plants. Formal scientific descriptions of the new monkeys are to be published in the scientific journal Neotropical Primates in the next few weeks, the Associated Press reports. – Reported on April 24 on Alloprimate

Paranthropus robustus Skull Found

Johannesburg – Paleontologists have announced the discovery of the most complete ape-man skull ever excavated, a 1.5-million- to 2-million-year-old skull of a female Paranthropus robustus, a cousin of early man. The fossil was found beside the lower jaw of a male in “one of the most extraordinary finds that any paleoanthropologist has ever seen,” said Lee Berger, director of paleoanthropology at the University of Witwatersrand.

The finds give researchers their best opportunity to compare the differences between males and females of the species, said Andre Keyser, the paleontologist in charge of the site where the fossils were found.

Paranthropus robustus, a hominid that lived between 1.5 million and 2 million years ago, was a vegetarian that may have used rudimentary bone tools, Keyser said. It became extinct about a million years ago, probably because of the domination of early man, he said. “They represent a creature that was in direct competition with our earliest ancestors.”

The fossils were discovered in October, 1994, at the Drimolen site 20 miles northwest of Johannesburg in an excavation area nicknamed “The Cradle of Humankind”. Paleontologists have uncovered 80 hominid specimens at Drimolen since it was discovered in 1992. The remains were found in a prehistoric cave filled with bones dumped there by flash floods more than a million years ago.

The nearly complete skull will give paleontologists research opportunities they never had with the disparate fragments previously discovered, Berger said. – From the Chicago Tribune, April 27, 2000 (A.P.), posted to Primate-Science

Texas Snow Monkey Sanctuary Joins API

On March 2 the Animal Protection Institute (API), a national non-profit animal advocacy organization based in Sacramento, California, announced that the Texas Snow Monkey Sanctuary (TSMS) of Dilley, Texas, is now operating as a division of API, which has approximately 85,000 members nationwide. The Sanctuary's mission to provide a free-ranging environment for primates in need remains unchanged, with API providing managerial support. – From an Animal Protection Institute Press Release, March 2, posted to Alloprimate

NIH Takes Charge of Coulston Chimps

The National Institutes of Health (NIH) has assumed responsibility for 288 chimpanzees currently housed at the Coulston Foundation in Alamogordo, New Mexico. The Coulston Foundation has been under scrutiny for financial troubles and violations of the Animal Welfare Act. Now that NIH has taken over responsibility for the chimpanzees, which have been used for HIV and hepatitis C research, the bidding process for contracts to care for the animals can begin. According to Nature magazine, bids will begin in June and will undergo peer review. Coulston can participate in the bidding process. – From the National Association for Biomedical Research Update, May 25, 21[11]

Changes at ILAR

The National Academies have named Joanne Zurlo, PhD, to be the Associate Director of the Institute for Laboratory Animal Research (ILAR) for the next six months. It is anticipated that she will then become ILAR's Director. Current ILAR Director Ralph Dell will remain as Associate Director for six months into 2001 to complete the transition of ILAR's leadership. He is looking forward to spending more time with his family and doing some consulting.

Joanne is currently the Associate Director of the Johns Hopkins Center for Alternatives to Animal Testing, which she joined in 1993. – An announcement by Americans for Medical Progress

Delta Airlines Will No Longer Ship Nonhuman Primates

As of June 1, Atlanta-based Delta Airlines will no longer transport nonhuman primates including lemurs, monkeys, orangutans, gorillas, and chimpanzees. According to Delta spokesperson Cindi Kurczewski, the decision was made by the airline's air logistics group to “provide the safest workplace environment possible for Delta employees.” “The animals were normally shipped as air cargo,” Kurczewski said, “and because we don't have protective gear and such for our cargo employees we implemented the policy to ensure their safety.” When asked to be more specific regarding safety concerns, Kurczewski said she could not comment.

In related news, a number of U.S. airlines recently announced a summer ban on animal cargo. Delta Airlines will not allow animals to be checked as baggage in June, July, and August. United and American Airlines announced similar bans through September, and Continental Airlines has permanently stopped accepting animals as checked baggage. In most instances small pets can still be carried aboard the airline and most companies have cargo instructions posted on-line. These restrictions come on the heels of new federal rules requiring airlines to report the number of animals killed or injured on flights – National Association for Biomedical Research Update, 21[5]

Research and Educational Opportunities

Fieldwork on Endangered Species

The Zoological Society of San Diego announces its Millennium Field Program in Conservation Science. Twelve post-doctoral positions are available (to be filled between 2000-2002) for fieldwork on endangered species (mammals, birds, reptiles, and amphibians) and ecosystems. Projects may be carried out in any part of the world, but attention will focus on five geographical regions: Southwestern U.S.A., South America, Caribbean Islands, Pacific Islands, and China, as well as on additional areas/species of particular interest to the Society (e.g., primates and rainforest herpetofauna of Cameroon). It is envisaged that postdoctoral fellows will carry out field projects in collaboration with staff at the Center for Reproduction of Endangered Species (CRES) as well as with the Society's Curatorial, Veterinary, and Educational Departments. The CRES laboratories, with a total of 70 scientists and technical staff, offer expertise in the fields of behavior, ecology and applied conservation, endocrinology, genetics, pathology, reproductive physiology, virology/ immunology and analytical chemistry. Funds for travel, equipment and field expenses will be included in each fellowship. Appointments will be for three years, with the possibility of extension to five years (maximum). Newly qualified PhDs, and those with up to three years postdoctoral experience, are encouraged to apply. Also available is a Conservation Education Fellowship for postgraduate students which will support the Zoological Society of San Diego's conservation and research projects through community outreach and awareness programs.

Awards Granted

AZA President's Award to Don Lindburg

Donald G. Lindburg, a founder and former president of the American Society of Primatologists, was awarded the American Zoo and Aquarium Association's President's Award. Lindburg is especially well-known for his work over 30 years on macaques, but has also studied cheetahs, lemurs, condors, rhinoceroses, drills, and golden monkeys. He was the editor of Zoo Biology, and is species co-ordinator for the giant panda. – From the ASP Bulletin, 1999, 23[2]

APA Award for Maestripieri

Dario Maestripieri, of the University of Chicago, will receive the American Psychological Association's Award for Distinguished Scientific Early Career Contribution to Psychology (Animal Learning and Behavior, Comparative), at the August meeting of the Association. The citation reads: “Dario Maestripieri, of the University of Chicago, is recognized for his contributions in the area of the psychobiology of primate infant development and maternal behavior. He has been able to elucidate the role hormones play in maternal interest in infants in rhesus monkeys. Understanding the mechanism of this hormonal influence will be valuable in understanding the complexity of mother-infant attachment.” During his studies of mother-infant interactions, Maestripieri noted that some mothers neglected or abused their infants. Using the Yerkes Primate Center's historical records he was able to investigate the consistency of this abuse; he demonstrated in two primate species that this abuse ran in families and was not randomly distributed across the social groups. He further found that neglect and abuse were not the same thing, as neglect occurred with first babies, where abuse occurred repeatedly across many births. This research promises to have important implications for understanding those human mothers who abuse their infants. – From <>

1999 “Breakthrough of the Year”

The weekly journal Science selected advances in stem cell research and technologies as 1999's “Breakthrough of the Year.” Recent innovations in stem cell research were catalyzed in part by the pioneering studies of Dr. James Thomson, a scientist at the Wisconsin RPRC. In 1995, Dr. Thomson and his colleagues succeeded in isolating and culturing embryonic stem cells from monkeys; they later applied their findings to the isolation of human embryonic stem cells, which are capable of differentiating into several types of tissues. – From the NCRR Reporter, Winter 2000, XXIV[1]

Establishment of a Tumor Register at the DPZ

For several years, the German Primate Center (DPZ) has been collecting a database on the occurrence of tumors in primates. This “Tumor Register” aims to provide a comprehensive record of the incidence of tumors in different primate species in order to facilitate research on this topic. The tumor register is a computer-based database which includes information on our own cases as well as archival material from the Instituts für Zoo- und Wildtierforschung Berlin and other primate-keeping institutions. The register, including individual animal data and materials (tissue samples, pictures, etc.) will be available on the DPZ Internet homepage.

As part of this project, we have collated an extensive reference collection on spontaneously occurring neoplasia in primates. The collection contains over 600 complete, up-to-date literature references and is now available via the DPZ homepage. The literature base is fully searchable (eg. by authors, titles or key words) and can be accessed under <>.

The literature base will be updated quarterly. Should you have any literature not already listed, we would be very pleased to include it in the register. A case registry will be available by Internet at the end of the year. We are also keen to further expand the register of individual primate tumor cases and would be delighted to cooperate with you in this. Should you have a primate with suspected or proven neoplasms, we would be very interested in examining the tumor and in registering all relevant details in the tumor register. Naturally, any investigations will be carried out in the scientific interest. Senders would of course be named in any scientific publications that might result. In the long term, our aim is to expand the register nationally and internationally.

If you would like to be informed of progress, please let us have your contact details so that we can include you in our regular updates. Should you have any queries or suggestions, please do not hesitate to contact us. Prof. Dr. med. vet. F.-J. Kaup and Dr. med. vet. P.

Primates de las Américas...La Página

En esta nueva oportunidad de comunicarnos, les ofrecemos un interesante ensayo escrito por la Dra. Rosalía Pastor-Nieto, la cual posee gran experiencia sobre el impacto negativo del tráfico de especies sobre los primates mexicanos. Asimismo, una vez más incluimos un breve relato en donde se pone de manifiesto el contacto ancestral de las comunidades indígenas con nuestros primates silvestres. Como siempre estamos a sus órdenes: Juan Carlos Serio Silva y Elva Mathiesen, Depto. de Ecología Vegetal, Instituto de Ecología AC, km 2.5 antigua carretera a Coatepec, Ap. 63 CP 91000, Xalapa, Veracruz, México [e-mail: <[email protected]>]

El Origen de los Monos Araña y Aulladores. Tomado del Popol Vuh, el libro sagrado de los Mayas. Se cuenta el origen tanto de los monos araña (ba'at en maya) como de los aulladores (ma'ax). Una vez una joven embarazada por Hun Hunahpú, el “Gran cazador”, llegó a casa de su suegra quien vivía con dos hijos previos de Hun Hunahpú, llamados Hunbatz y Hunchuen, muy queridos por la abuela. La joven dio a luz a los gemelos Hunahpú e Ixbalanqué, quienes eran despreciados por sus medios hermanos, y estos los hacían trabajar duramente mientras cantaban y tocaban música.

Un día, los gemelos decidieron deshacerse de ellos diciéndoles que habían dejado unas aves para la comida en un árbol. Cuando Hunbatz y Hunchuen subieron a éste, el tronco se hizo muy grueso y creció tanto que no pudieron bajar. Por ser tan soberbios, los hermanos se convirtieron entonces en monos: Hunbatz se transformó en el saraguato y Hunchuen en el mono araña.

El Tráfico de Primates Nativos de México y el Impacto en su Conservación. Dra. Rosalía Pastor Nieto. México posee dos géneros y tres especies de primates Neotropicales: los monos aulladores o “saraguatos” (Alouatta palliata mexicana y Alouatta pigra) y los monos araña (Ateles geoffroyi vellerosus y Ateles geoffroyi yucatanensis), los cuales habitan los remanentes de selva del sur de México. Ante la reducción del hábitat y las amenazas sobre sus poblaciones, estas especies de primates se ubican dentro de los Apéndice I y II del CITES. Esta situación, las coloca junto a otras especies de fauna, cuyas poblaciones silvestres se encuentran seriamente amenazadas por el tráfico ilegal, por lo que se han instrumentado permisos especiales de importación y exportación de especimenes vivos. Dado que estas especies todavía se localizan en los manchones de selva del sur de México, tanto autoridades estatales como federales encargadas de vigilar y evitar el tráfico ilegal, deberían poner especial énfasis en su protección.

Tristemente, la venta de infantes de primates en las carreteras de los estados sureños de México, continua descaradamente. Los lectores de estas líneas deben conocer el fuerte impacto que implica tener a uno de estos primates como parte de la “familia”. Por cada infante que se vende a pie de carretera o en el mercado negro, mueren al menos 10 adultos tratando de defender al infante. Solamente muerta la madre se desprende de su cría.

Las repercusiones de la cacería ilegal de primates no sólo son ecológicas sino también de salud. Es bien sabido que los humanos y los primates no-humanos, compartimos un sinfín de patologías, muchas de ellas mortales, como la polio, sarampión, tuberculosis, y herpes entre tantas. Además, tener a un animal atado en traspatio en cualquiera de nuestras casas del sur del país, implica que en época de lluvias se tiene en “casa” a un verdadero reservorio de la enfermedad del dengue. Por lo tanto su posesión no se justifica ni en lo moral, ni en lo ecológico, y mucho menos por razones de salud. Por otro lado, los infantes de mono saraguato y mono araña son especialmente atractivos y mientras son pequeños son manejables. Sin embargo los problemas comienzan cuando los especimenes llegan a la edad adulta y su conducta se torna impredecible, además de incontrolable. Por ello, las familias optan por donarlos a zoológicos con la mejor voluntad de incorporarlos con los de su especie. La verdad de las cosas es que estos animales se encuentran en un callejón sin salida. Por un lado, los saraguatos son especialmente delicados y requieren del conocimiento de un especialista para lograr su manejo correcto y su rehabilitación exitosa. Al ser animales estrictamente vegetarianos en vida libre, tienen una dieta muy exigente, además que son especialmente sensibles a los cambios sociales. Por otro lado los monos araña, a pesar de su adaptación al cautiverio entre humanos, son especialmente sensibles a enfermedades gastrointestinales por amibas y giardias ya que por su origen arbóreo no poseen las defensas naturales contra estas enfermedades.

En conclusión, la merma poblacional de primates de México es multifactorial, y pareciera que como “solo son monos”, son el ridículo espejo de nosotros mismos, mereciendo de nosotros únicamente nuestra burla. La realidad es otra, obviamos que son criaturas maravillosas, con una increíble capacidad social e intelectual, y que han ocupado un lugar importante dentro de los ecosistemas tropicales y que sólo por ello, y el asombro que provoca en nosotros su existencia, merecerían un especial esfuerzo para su preservación.

Anatomy & Physiology

*Body weight of wild and captive common marmosets (Callithrix jacchus). Araújo, A., Arruda, M. F., Alencar, A. I., Albuquerque, F., Nascimento, M. C., & Yamamoto, M. E. (Sector of Psychobiology, Dept of Physiology, Univ. Federal do Rio Grande do Norte, Caixa Postal 1511-Campus Universitário, 59072-970 Natal RN Brazil). International Journal of Primatology, 2000, 21, 317-324.
. . . We compared body weights of captive and wild Callithrix jacchus obtained by repeatedly weighing subjects from two populations in Brazil: 138 individuals from our University colony, and 243 individuals in 15 free-ranging groups from a field site in Nísia Floresta. We assigned all subjects to one of four age classes – infant, juvenile, subadult, and adult – according to their birth dates or size, reproductive status, and dental development. There is no significant difference between males and females in any of the four age classes, but captive subjects were heavier than wild ones in all age classes but infant. Reproductive and nonreproductive adult females showed no statistical difference in weight. These results suggest that differences between wild and captive animals are not constitutional, but are a consequence of diet and physical activity. The absence of weight differences between reproductive and nonreproductive females suggests that any possible advantage from high rank is outweighed by the costs of reproduction in common marmosets.

*Reversal of anti-psychotic induced working memory deficits by short-term dopamine D1 receptor stimulation. Castner, S. A., Williams, G. V., & Goldman-Rakic, P. S. (P. S. G.-R., Section of Neurobiology, Yale Univ. School of Medicine, 333 Cedar St, New Haven, CT 06510). Science, 2000, 287, 2020-2022.
. . . Chronic blockade of dopamine D2 receptors, a common mechanism of action for antipsychotic drugs, down-regulates D1 receptors in the prefrontal cortex and, as shown here, produces severe impairments in working memory. These deficits were reversed in monkeys by short-term coadministration of a D1 agonist, ABT 431, and this improvement was sustained for more than a year after cessation of D1 treatment. These findings indicate that pharmacological modulation of the D1 signaling pathway can produce long-lasting changes in functional circuits underlying working memory. Resetting this pathway by brief exposure to the agonist may provide a valuable strategy for therapeutic intervention in schizophrenia and other dopamine-dysfunctional states.

*Language discrimination by human newborns and by cotton-top tamarin monkeys. Ramus, F., Hauser, M. D., Miller, C., Morris, D., & Mehler, J. (Institute of Cognitive Neuroscience, 17 Queen Square, London WC1N 3AR, U.K.). Science, 2000, 288, 349-351.
. . . Humans, but no other animals, make meaningful use of spoken language. What is unclear, however, is whether this capacity depends on a unique constellation of perceptual and neurobiological mechanisms or whether a subset of such mechanisms is shared with other organisms. To explore this problem, parallel experiments were conducted on human newborns and cotton-top tamarin monkeys to assess their ability to discriminate unfamiliar languages. A habituation-dishabituation procedure was used to show that human newborns and tamarins can discriminate sentences from Dutch and Japanese but not if the sentences are played backward. Moreover, the cues for discrimination are not present in backward speech. This suggests that the human newborns' tuning to certain properties of speech relies on general processes of the primate auditory system.

*In vitro manipulation of nonhuman primate gametes for embryo production and embryo transfer. Sankai, T. (Tsukuba Primate Center, Nat. Inst. Infectious Diseases, Hachimandai-1, Tsukuba, Ibaraki 305-0843, Japan). Experimental Animals, 2000, 49, 69-81.
. . . This article summarizes research on in vitro manipulation of nonhuman primate gametes, from collection of reproductive cells and in vitro fertilization to the birth of offspring after embryo transfer, as well as the current status of these research areas. The studies summarized here will directly lead to the development of standard techniques for practical and comprehensive use in nonhuman primates.

*Birth of the Japanese monkey (Macaca fuscata) infant following in-vitro fertilization and embryo transfer. Torii, R., Hosoi, Y., Masuda, Y., Iritani, A., & Nigi, H. (Inst. For Experimental Animals, Siga Univ. of Med. Science, Tsukinowa-cho, Seta, Ohtsu, Shiga 520-2192, Japan). Primates, 2000, 41, 39-47.
. . . The first successful birth by in-vitro fertilization (IVF) and embryo transfer (ET) in the Japanese monkey is described. IVF was carried out by using oocytes collected after ovarian stimulation and sperm collected by rectal electro-ejaculation. The embryos were incubated for 36-66 hours and then transferred to the fallopian tube of the recipient via the fimbria under laparoscopic observation. Four recipients received their own embryos and six received donor embryos. Two recipients that received donor embryos became pregnant after receiving one 3-cell and one 2-cell embryo, and one 4-cell and one 2-cell embryo, respectively. One healthy male infant was delivered 166 days after ET, but the other was aborted on day 128.

*Partial hepatectomy of marmoset: Clinical and pathological effects and utility in microsomal enzyme analysis. Kurata, Y., Makinodan, F., Matsumoto, J., Toyota, N., & Tanaka, K. (Mitsubishi Chem. Safety Inst. Ltd., 14 Sunayama, Hasaki-machi, Kashima-gun, Ibaraki, 314-0255, Japan). Experimental Animals, 2000, 49, 91-96.
. . . Liver biopsy based on a partial hepatectomy technique (shearing) was performed in 10 common marmosets (Callithrix jacchus) in a preliminary study to evaluate the effects of drugs on hepatic microsomal enzymes, cytochrome P-450 and T4 uridine diphosphate glucuronyl transferase, by comparing post-treatment with pre-treatment values individually with a limited number of animals. The effects of the biopsy on clinical findings and liver pathology were evaluated during the first five post-surgical weeks. Although the plasma aspartate aminotransferase activities tended to decrease from 1 to 4 weeks post-surgery, no abnormality was noted in clinical signs, body weight, hematocrit value, or other blood chemical values. At necropsy, adhesion of the sheared site of the liver to the parietal peritoneum or the small intestine was evident in 2 marmosets. Microscopic examination revealed focal fibrosis in the liver, but it was localized around the sheared site. It was concluded that liver biopsy must be performed more than one month before administration of the drug to be tested.

*Upgrading of flow cytometric analysis for absolute counts, cytokines and other antigenic molecules of cynomolgus monkeys (Macaca fascicularis) by using anti-human cross-reactive antibodies. Yoshino, N., Ami, Y., Terao, K., Tashiro, F., & Honda, M. (AIDS Research Center, Nat. Inst. Infectious Diseases, Shinjuku-ku, Tokyo 162-8640, Japan). Experimental Animals, 2000, 49, 97-110.
. . . The cross-reactions with various antigens from cynomolgus monkeys of more than 300 anti-human monoclonal antibodies (mAbs) were studied. Two hundred twenty-nine of 339 (67.55%) anti-human mAbs that react with human antigens of CD-defined molecules, chemokine receptors, and T cell receptors were cross-reactive with the monkey antigens. Using the cross-reactive antibodies and fluorescenced beads for calibration, the procedure for the absolute count of monkey lymphocyte subsets was developed and the mean values for CD4+ and CD8+ lymphocyte subsets in peripheral blood were 718 and 573/mm3, respectively. Moreover, intracellular cytokines, IL-2, IL-4 and IFNã, and intracellular apoptosis-related proteins, Bcl-2, FADD and the active form of caspase-3 could be detected in peripheral blood mononuclear cells as well as in various tissue cells. It is therefore practicable to detail the phenotype of leukocytes, assess the production of intracellular cytokines, and enumerate T-lymphocyte subsets by using the cross-reactive human antibodies with respective antigens of cynomolgus monkeys.


*Ant dipping and meat eating by wild chimpanzees in the Kalinzu Forest, Uganda. Hashimoto, C., Furuichi, T., & Tashiro, Y. (Primate Res. Inst., Kyoto Univ., Kanrin, Inuyama, Aichi 484-8506, Japan). Primates, 2000, 41, 103-108.
. . . New evidence of ant dipping and meat eating by chimpanzees was recorded in the Kalinzu Forest, Uganda. We found stems and branches at the nests of driver ants, Dorylus molestus, just after chimpanzees had left the spot. Fecal samples also revealed that chimpanzees sometimes ate driver ants. The configuration of stems and branches and the condition of holes at the driver ants' nests suggested that chimpanzees used the sticks as wands to dip for ants. The frequency of ant dipping and length of wands may be more related to cultural than ecological factors. Although hunting was not seen, we found chimpanzees eating a blue monkey and a redtail monkey. In both cases, they ate meat and leaves alternately, and shared meat with each other.

*Infant killing, wounding and predation in Eulemur and Lemur. Jolly, A., Caless, S., Cavigelli, S., Gould, L., Pereira, M. E., Pitts, A., Pride, R. E., Rabenandrasana, H. D., Walker, J. D., & Zafison, T. (Dept of Ecology & Evolutionary Biol., Princeton Univ., Princeton, NJ 08544). International Journal of Primatology, 2000, 21, 21-40.
. . . Infant killing by primates is highly controversial. Sexual selection of infanticidal males has been disputed, especially for seasonally breeding species, in which death of an infant does not advance conception of the next infant. We report attacks, infants found wounded, and predation in seasonally breeding Eulemur and Lemur at Berenty, Beza Mahafaly, and Duke University Primate Center, and review cases seen elsewhere. Observed attacks leading to wounds or death conservatively total twelve by extratroop males, two by troop males, and seven by troop females. Eulemur are occasional vertebrate predators, whose prey includes infant Lemur catta. Wounds inflicted by lemurs are usually abdominal canine slashes or bites to the head, with rare eating, a pattern distinct from carnivore and raptor kills. Infant killing as inferred from corpses is more frequent than previously thought, but still rare. Adaptive advantages of killing plausibly include eliminating resource competitors of females, and sexual selection on males.

*Infanticide by a male Milne-Edwards' sportive lemur (Lepilemur edwardsi) in Ampijoroa, NW-Madagascar. Rasoloharijaona, S., Rakotosamimanana, B., & Zimmerman, E. (Dépt de Paléontologie et d'Anthropologie biologique, Univ. d'Antananarivo, Madagascar). International Journal of Primatology, 2000, 21, 41-45.
. . . During a long-term field study on the behavioral ecology and communication of a population of the monogamous Lepilemur edwardsi, we recorded for the first time an infanticide in a nocturnal lemur. A male newcomer killed the infant of a female whose male partner had left her recently. Both the social-pathology and the sexual-selection hypotheses may explain this behavior.


*Nonrandom extinction and the loss of evolutionary history. Purvis, A., Agapow, P.-M., Gittleman, J. L., & Mace, G. M. (Department of Biology, Imperial College, Silwood Park, Ascot SL5 7PY, U.K.). Science, 2000, 288, 328-330.
. . . The hierarchical nature of phylogenies means that random extinction of species affects a smaller fraction of higher taxa, and so the total amount of evolutionary history lost may be comparatively slight. However, current extinction risk is not phylogenetically random. We show the potentially severe implications of the clumped nature of threat for the loss of biodiversity. An additional 120 avian and mammalian genera are at risk compared with the number predicted under random extinction. We estimate that the prospective extra loss of mammalian evolutionary history alone would be equivalent to losing a monotypic phylum.

*Primate community dynamics in old growth forest over 23.5 years at Ngogo, Kibale National Park, Uganda: Implications for conservation and census methods. Mitani, J. C., Struhsaker, T. T., & Lwanga, J. S. (Dept of Anthropology, Univ. of Michigan, Ann Arbor, MI 48109-1382). International Journal of Primatology, 2000, 21, 269-286. Few data exist regarding long-term changes in primate populations in old-growth, tropical forests. In the absence of this information, it is unclear how to assess population trends efficiently and economically. We addressed these problems by conducting line-transect censuses 23.5 years apart at the Ngogo study area in Kibale National Park. We conducted additional censuses over short time intervals to determine the degree to which the temporal distribution of censuses affected estimates of primate numbers. Results indicate that two species, blue monkeys and red colobus, may have experienced significant reductions over the past 23.5 years at Ngogo. In contrast, five other species, baboons, black-and-white colobus, chimpanzees, mangabeys, and red-tailed guenons, have not changed in relative abundance. Additional findings indicate that different observers may vary significantly in their estimates of sighting distances of animals during censuses, thus rendering the use of measures of absolute densities problematic. Moreover, cnesuses conducted over short periods produce biased estimates of primate numbers. These results provide guidelines for the use of line-transect censuses and underscore the importance of protecting large blocks of forest for primate conservation.

*Conflict of interest between people and baboons: Crop raiding in Uganda. Hill, C. M. (Dept of Anthropology, School of Social Sciences and Law, Oxford Brookes Univ., Oxford OX3 OHP, U.K.). International Journal of Primatology, 2000, 21, 299-315.
. . . The aim of this paper is to examine the impact of crop raiding by primates, particularly baboons, on farmers living around the southern edge of the Budongo Forest Reserve, Uganda. Data gathered during monthly farm surveys and informal discussion groups, along with time budget data, demonstrate that 1) baboons can cause extensive damage to field crops, such as maize and cassava; 2) proximity of the farm to the forest edge and the presence or absence of neighboring farms affect the likelihood of any farm sustaining crop damage from baboons; and 3) in addition to the direct costs associated with crop losses attributed to baboon foraging activity, there are indirect costs of baboon crop raiding such as increased labor demands to protect crops from them and, occasionally, to replant crop stands badly damaged by baboons. These results have important implications for future primate conservation policy and practice.


*The development of behavioural sex differences in infant rhesus macaques (Macaca mulatta). Brown, G. R. & Dixson, A. F. (Sub-Dept of Animal Behaviour, Univ. of Cambridge, Madingley, Cambridge, CB3 8AA, U.K.). Primates, 2000, 41, 63-77.
. . . The behavior of 14 male and 20 female infants and their mothers was studied during the first six months of life, including measures of play behavior, socio-sexual mounting, and mother-infant interactions. Data reveal that, on average, male infants exhibited more rough-and-tumble play and mounting than female infants, and also exhibited stationary play and chasing play, and initiated play, more frequently than females. Such sex differences appear to be robust in macaques and have been reported in a variety of housing conditions. Male and female infants did not differ in the amount of time spent at particular distances from their mothers, and mothers were not found to behave differently towards sons and daughters, according to measures of restraint, rejection, and grooming.

*Impaired reconciliation in rhesus macaques with a history of early weaning and disturbed socialization. Ljungberg, T. & Westlund, K. (Div. of Ethology, Dept. of Zoology, Univ. of Stockholm, S-106 91, Stockholm, Sweden). Primates, 2000, 41, 79-88.
. . . An attempt had been made to create five social groups from rhesus macaques with a history of early separation from their mothers, early weaning and hand feeding, and, in most cases, previous housing in single cages. We investigated the exchange of affiliative behaviors after an aggressive encounter and selective attraction to the former opponent, a phenomenon previously well described in rhesus monkeys. Evidence for reconciliation was found in only one of the five groups. This group consisted of younger animals that had, at least temporarily, been living together after separation from their mothers. In the other groups studied, containing animals with varied backgrounds, aggressive interactions were not followed by affiliative behaviors or attraction between former opponents, suggesting that the use of reconciliatory behaviors in adult monkeys is dependent upon social training.


*Timing the ancestor of the HIV-1 pandemic strains. Korber, B., Muldoon, M., Theiler, J., Gao, F., Gupta, R., Lapedes, A., Hahn, B. H., Wolinsky, S. & Bhattacharya, T. (Los Alamos National Laboratory, Los Alamos, NM 87545). Science, 2000, 288, 1789-1796.
. . . HIV-1 sequences were analyzed to estimate the timing of the ancestral sequence of the main group of HIV-1, the strains responsible for the AIDS pandemic. Using parallel supercomputers and assuming a constant rate of evolution, we applied maximum-likelihood phylogenetic methods to unprecedented amounts of data for this calculation. We validated our approach by correctly estimating the timing of two historically documented points. Using a comprehensive full-length envelope sequence alignment, we estimated the date of the last common ancestor of the main group of HIV-1 to be 1931 (1915-41). Analysis of a gag gene alignment, subregions of envelope including additional sequences, and a method that relaxed the assumption of a strict molecular clock also supported these results.

*Dracunculiasis in a south Indian bonnet monkey. Sankar, V., Prakash, S., Muthusamy, R., & Kamakshi, K. (Dept of Anatomy, A. L. Mudaliar Postgrad. Inst. of Basic Med. Sciences, Univ. of Madras, Taramani Campus, Chennai 600 113, India). Primates, 2000, 41, 89-92.
. . . Dracunculiasis, popularly known as Guinea worm disease, has been eradicated from Tamil Nadu, India, and there have been no indigenous cases reported since 1981. This report describes a female bonnet monkey with dracunculiasis. She presented with fever and a blister in her left hind limb. The blister ruptured on exposure to water and a 7-cm-long worm was extruded. The worm died before it could be histologically examined. The diagnosis was based on the typical clinical course, which was pathognomonic of dracunculiasis. This case raises the question of whether wild monkeys might act as reservoirs of human infection and cause resurgence of the disease in south India.

Evolution, Genetics, and Taxonomy

*The oldest known anthropoid postcranial fossils and the early evolution of higher primates. Gebo, D. L., Dagosto, M., Beard, K. C., Qi, T., & Wang, J. (Dept of Anthropology, Northern Illinois Univ., DeKalb, IL 60115) Nature, 2000, 404, 276-278.
. . . The middle Eocene primate family Eosimiidae, which is known from sites in central and eastern China and Myanmar, is central to efforts to reconstruct the origin and early evolution of anthropoid or “higher” primates (monkeys, apes and humans). Previous knowledge of eosimiid anatomy has been restricted to the dentition and an isolated petrosal bone, and this limited anatomical information has led to conflicting interpretations of early anthropoid phylogeny. Here we describe foot bones of Eosimias from the same middle Eocene sites in China that yield abundant dental remains of this primate. Tarsals of Eosimias show derived anatomical traits that are otherwise restricted to living and fossil anthropoids. These new fossils substantiate the anthropoid status of Eosimias and clarify the phylogenetic position of anthropoids with respect to other major primate clades. Early anthropoids possessed a mosaic of primitive and derived traits in their postcranial skeletons, reflecting their derivation from haplorhine ancestors that retained many prosimian-like features.

*Molecular analysis of Neanderthal DNA from the northern Caucasus. Ovchinnikov, I. V., Götherström, A., Romanova, G. P., Kharitonov, V. M., Lidén, K., & Goodwin, W. (W.G., Human Identification Centre, University of Glasgow, Glasgow G12 8QQ, Scotland). Nature, 2000, 404, 490-493.
. . . The expansion of premodern humans into western and eastern Europe ~40,000 years before the present led to the eventual replacement of the Neanderthals by modern humans ~28,000 years ago. Here we report the second mitochondrial DNA (mtDNA) analysis of a Neanderthal, and the first such analysis on clearly dated Neanderthal remains. The specimen is from one of the eastern-most Neanderthal populations, recovered from Mezmaiskaya Cave in the northern Caucasus. Radiocarbon dating estimated the specimen to be ~29,000 years old and therefore from one of the latest living Neanderthals. The sequence shows 3.48% divergence from the Feldhofer Neanderthal. Phylogenetic analysis places the two Neanderthals from the Caucasus and western Germany together in a clade that is distinct from modern humans, suggesting that their mtDNA types have not contributed to the modern human mtDNA pool. Comparison with modern populations provides no evidence for the multiregional hypothesis of modern human evolution.

*Phylogenetic relationships of spider monkeys (Ateles) based on mitochondrial DNA variation. Collins, A. C. & Dubach, J. M. (Dept of Anthropology/Sociology, 119 Northview Hall, 1500 University Dr., Univ. of Wisconsin College, Waukesha, WI 53188). International Journal of Primatology, 2000, 21, 381-420.
. . . Samples were obtained from most previously recognized subspecies of Ateles to determine phylogenetic relationships among racially recognized groups. Comparison of DNA sequences using both parsimony analysis and genetic distance analysis produced phylogenetic relationships that were very similar for each genetic region. Analysis of the phylograms identified four monophyletic species of Ateles: Ateles paniscus, composed of haplotypes from the northeastern Amazon Basin; A. belzebuth in the southern Amazon Basin; A. hybridus, located primarily along the Magdalena River valley of Colombia; and A. geoffroyi, which includes two former species: A. geoffroyi and A. fusciceps. This arrangement is contradictory to long-held taxonomies of Ateles based on pelage variation and is similar to a recent analysis based on craniodental variation.

*Biogeographic and ecologic forces responsible for speciation in Ateles. Collins, A. C. & Dubach, J. M. (Address same as above). International Journal of Primatology, 2000, 21, 421-444.
. . . The results of the study above were used to investigate questions of evolutionary origin and speciation mechanisms. Most speciation among the various species of Ateles occurred during the middle to late Pliocene, suggesting that Pleistocene refuge formation was not a key speciation mechanism. Large-scale geographic changes associated with the continued rise of the eastern and western cordilleras of the northern Andes and associated changes in habitat were the most important causes of speciation in Ateles.

*Intraspecific variation in the vocalization and hand pad morphology of southern lesser bush babies (Galago moholi): A comparison with G. senegalensis. Anderson, M. J., Ambrose, L., Bearder, S. K., Dixson, A. F., & Pullen, S. (Sub-Dept of Animal Behaviour, Univ. of Cambridge, Madingley, Cambridge CB3 8AA, U.K.). International Journal of Primatology, 2000, 21, 537-555.
. . . Examination of calls recorded from different regions along a transect of 1500 km across southern Africa revealed low levels of intraspecific variation in Galago moholi, whereas comparisons with homologous call-types in G. senegalensis revealed them to be significantly different. Volar pad measurements across the ranges of both species also showed low levels of intraspecific variation and relatively high interspecific variation. These findings demonstrate that vocal and volar pad characteristics can be used as consistent measures of difference between species that look almost identical.

*Discovery of complete arm and hand of the 3.3 million-year-old Australopithecus skeleton from Sterkfontein. Clarke, R. J. (Dept of Anthropology and Human Genetics, J. W. Goethe Univ., Siesmayerstr. 70, D-60323 Frankfurt am Main, Germany). South African Journal of Science, 1999, 95, 477-480.
. . . In 1998 the discovery of a complete skull and some limb bones of an Australopithecus was announced. They was estimated to be 3.33 million years old. Now additional parts of the same skeleton have been unearthed. The principal significance of this fossil arm and hand is that, for the first time, the forelimb of an Australopithecus can be studied as a complete unit. There is potential for understanding the way in which it functioned and its evolutionary relationship to the arms and hands of modern humans and apes. It also implies that the rest of the body is buried at the same site.

Field Studies

*Primate community structure in Guyana: A biogeographic analysis. Lehman, S. M. (Dept of Anthropology, SUNY, Stony Brook, NY 11794-4364). International Journal of Primatology, 2000, 21, 333-351.
. . . An analysis of primate species at 16 sites, using data from 1725 km of line-transect censuses to determine specific composition and association patterns of 220 primate groups. Of the 18 polyspecific groups, 16 included squirrel monkeys. There was an overall trend towards positive specific associations among Guyanese primates. The only species that exhibited a negative pattern of interspecific associations were brown and wedge-capped capuchins. Low plant productivity in Guyanese forests may reduce the diversity of feeding niches and result in a low incidence of polyspecific associations and scramble competition between wedge-capped and brown capuchins.

*Distribution and forest utilization of Saguinus and other primates of the Pando Department, northern Bolivia. Buchanan-Smith, H. M., Hardie, S. M., Caceres, C., & Prescott, M. J. (Scottish Primate Research Group, Dept of Psychology, Univ. of Stirling, Stirling, FK9 4LA, Scotland). International Journal of Primatology, 2000, 21, 353-379.
. . . A four-month census gave no evidence of a previously reported presence of two populations of Saguinus mystax, nor of Lagothrix. The distribution of S. imperator appears more restricted than previously reported, but the presence of Cebuella south of the Rio Tahuamanu was confirmed. Data on group sizes, habitat utilization, and locomotor behavior of the primates is compared with previous studies. Differences in body size, diet, foraging techniques, and vertical use of the forest appear to be key factors in both sympatry and in the formation of polyspecific associations.

*Ranging behavior of proboscis monkeys (Nasalis larvatus) in the lower Kinabatangan, northern Borneo. Boonratana, R. (P.O. Box 54, Chiang Mai Univ., Chiang Mai 50202, Thailand). International Journal of Primatology, 2000, 21, 497-518.
. . . Data collected via scan samples during group follows at two sites. Groups of N. larvatus had ranges overlapping those of other groups in each area, with no territorial behavior observed. Both groups occasionally swam across the Kinabatangan River, and frequently across its tributaries. The home range size of one group was 220.5 ha. This group traveled farther on days when the proportion of young leaves in the diet was higher.


*Diet of buffy tufted-eared marmosets (Callithrix aurita) in a forest fragment in southeastern Brazil. Martins, M. M. & Setz, E. Z. F. (Depto de Zool., Inst. de Biologia, Univ. Estadual de Campinas, C.P. 6109, 1308-970 Campinas, SP, Brazil). International Journal of Primatology, 2000, 21, 467-476.
. . . We recorded daily feeding activities over one year in a 17-ha semi-deciduous forest fragment, using scan sampling at 5-min intervals. The marmosets devoted feeding time to gums (50.5%), fruits (11%), and animal prey (38.5%) in a total of 499 records. Plant resources comprised 27 species from 16 families. The marmosets preyed on caterpillars (33%), katydids (5%), and homopterans (4%). Feeding on fruits varied seasonally and was inversely related to gum feeding.

*Composition and proposed nutritional importance of exudates eaten by saddleback (Saguinus fuscicollis) and mustached (Saguinus mystax) tamarins. Smith, A. C. (Dept of Psychology, Univ. of Stirling, Stirling, FK9 4LA, Scotland). International Journal of Primatology, 2000, 21, 69-83.
. . . The first comprehensive data on the composition and mineral content of exudates eaten by saddleback and mustached tamarins, and assessment of Garber's hypotheses on the potential nutritional importance of exudates in the diet of tamarins. In accordance with his initial findings, nutritional analyses show that the gums consumed are relatively high in calcium and may serve to balance a diet otherwise low in this mineral and high in phosphorus. However, the data on the seasonal variation in the amount consumed do not support the hypothesis that exudates are of particular nutritional importance during the later stages of gestation or lactation for these animals.

*Influence of temperature on energy intake and food selection by macaques. Agetsuma, N. (Dept of Economics, Akita Univ. of Economics and Law, Mamorisawa 46-1, Shimokitate-Sakura, Akita, 010-0058 Japan). International Journal of Primatology, 2000, 21, 103-111.
. . . “I examined the influence of temperature on food intake in four captive macaques, three Macaca fuscata and one M. mulatta. I gave them two types of artificial food pellets which were different in energy content per weight at six different air temperatures. Total energy intake increased as temperature decreased. Intake of low-quality pellets increased significantly with decreasing temperature in three subjects. The other (not the rhesus), whose food intake was almost constant, decreased his body weight as ambient temperature decreased. I discuss the pattern of food selection found in this experiment from the viewpoint of optimal foraging strategy.”


*Signaling of reproductive status in captive female golden-headed lion tamarins (Leontopithecus chrysomelas). De Vleeschouwer, K., Heistermann, M., Van Elsacker, L., & Verheyen, R. F. (Section Scientific Research, Royal Zool. Soc. of Antwerp, Koningin Astridplein 26, 2018 Antwerp, Belgium). International Journal of Primatology, 2000, 21, 445-465.
. . . We used a combination of behavioral observations and endocrine data to determine female reproductive status and to examine changes in sociosexual behaviors over the ovarian cycle and between conceptive and nonconceptive cycles. Females clearly signaled their reproductive status by proceptive sexual presenting. Males showed increased frequencies of anogenital sniffing and mounting during the fertile period, indicating that they detected changes in olfacory and behavioral cues emitted by females, and adjusted their mounting behavior accordingly. Males and females also remained in closer proximity before and during the fertile period, suggesting the existence of mate guarding.
