Although post-conceptive sexual activity has widely been reported in Japanese macaques (Macaca fuscata; see e.g., Eaton, 1978; Mitsunaga et al., 1992; Nigi et al., 1990; Soltis et al., 2002; Takahata, 1980; Wolfe, 1979), the relationship between such behavior and the hormonal status of the females has not been previously documented. Pregnancy is associated with marked fluctuations in concentrations of progesterone and estrogen, which are known to affect behavior (Dixson, 1998; Soltis et al., 1999). This study examines hormonal correlates of post-conceptive mating in the Arashiyama West group of Japanese macaques.

In captivity, rhesus monkeys have been observed to copulate during pregnancy, displaying a secondary peak in mating between the 6th and 10th week of gestation, when progesterone levels temporarily drop (Bielert et al., 1976). Furthermore, Wilson et al. (1982) found that female rhesus who displayed post-conceptive mating activity exhibited a drop in progesterone concentrations below an apparently critical level, whereas females who did not exhibit post-conceptive mating had comparatively higher concentrations of progesterone.

Female pig-tailed macaques also exhibit a peak in mating between weeks 4 and 10 (Maestripieri, 1999); however they do not show a decrease in progesterone levels until week 16, by which time the frequency of post-conceptive mating activity has all but ceased. In addition, some non-macaque cercopithecoid species have been reported to exhibit post-conceptive mating (e.g., sooty mangabeys: Gust, 1994; blue monkeys: Pazol, 2003) and at least one of these (Hanuman langurs: Sommer, 1993) showed a peak in post-conceptive mating during the 6th to 10th week of gestation.

Here we describe the hormonal correlates as well as the timing, frequency, and sex of partners involved in post-conceptive mating, information that may shed some light on the etiology of this form of nonconceptive mating in Japanese macaques. Our objective was to examine the timing of mating during the gestational period and the relationship to changing levels of excreted reproductive steroid metabolites.


The subjects were 8 adult female Japanese macaques living in a 65-acre enclosure at the Arashiyama West Texas Snow Monkey Sanctuary. For details of group structure and history, see O’Neill, 2000, and Fedigan & Asquith, 1991. Behavioral data were collected from October through April during the 1997/1998 breeding season. A total of 41 to 48 hours of focal data per female were collected. For the females that conceived, approximately 30 to 35 hours of that data was during gestation. Focal data were collected daily, but each female was followed only 3 or 4 times/week. Fecal samples were collected two to three times per week from each of the eight target females between the hours of 8:00 a.m. and 6:00 p.m.

The two main fecal metabolites of estrogens are estradiol and estrone, and the progestins may metabolize as progesterone or pregnanediol. Analysis by radioimmunoassay revealed that estrone and pregnanediol were the most abundant fecal metabolites of estrogens and progestins in female Japanese macaques. Extraction of ovarian steroids (estrone-glucuronide [E1] and pregnanediol-glucuronide [PdG]) was performed as described by Strier and Ziegler (1997) and Ziegler et al. (1997). Fecal samples were analyzed using enzyme immunoassays; see O’Neill (2000) and O’Neill et al. (2004b), for a detailed description of assays and validations.

Hormone profiles were used to calculate ovulatory cycle and gestation lengths. Copulatory activity during pregnancy was analyzed for the four females who conceived and carried to term during the 1997/1998 mating season. Data were collected from the first week through the 12th-19th week of gestation for the four females (Table 1). The earliest possible day of conception was considered to be the estimated day of ovulation when PdG levels failed to return to their lowest baseline levels. The length of gestation was calculated as the interval between the estimated day of ovulation during the cycle in which conception occurred and the date of parturition. Parturition dates were defined as the first day in which the female was observed with a new infant and were accurate to within two days.

A Spearman nonparametric correlation was used to analyze the relationship between hormone levels and mounting behavior during pregnancy.


Hormone levels during early pregnancy

Mean PdG levels were 50.01 ng/g in the first week of gestation, increasing to 100.70 ng/g by the 5th week, followed by a temporary drop in weeks 6 through 8, averaging 56.03 ng/g, then steadily increasing to 131.18 ng/g by the 18th week (Figure 1). E1 levels were highly variable for the initial weeks of gestation, but then showed a steady increase by the 14th week (Figure 1). A positive correlation was found between PdG and E1 levels (Spearman: rs= 0.51, P<0.05), showing a parallel rise in both hormones as the pregnancy nears term.

During the study period, four of the eight females conceived after 1 to 4 cycles. The mean gestation length for the four females that carried to term was calculated to be 175 ± 12.8 days (Table 1, median=173 days).

Post-conceptive mating

The majority of post-conceptive mating occurred during weeks 6-11 of gestation (Figure 1). The rate of post-conceptive mounts was similar for both heterosexual and same-sex pairs (mounts received: 13.17/hour for same-sex and 16.86/hour for heterosexual; mounts directed: 5.13/hour for same-sex and 5.67/hour for heterosexual). We have previously reported that same-sex mating presents very similar patterns to heterosexual mating activity (O’Neill et al., 2004a).

We found that weeks with higher levels of mounting were significantly associated with decreases in PdG levels relative to the previous week (Spearman: rs = 0.59; p < 0.05).


The mean gestation length that we calculated for these Japanese macaque females was comparable to earlier findings based on non-hormonal studies. Nigi (1976) reported a mean gestation length of 173 ± 6.9 days and Kawai (1966) reported a gestation period of 171-180 days.

Figure 1: Mean pregnanediol (PdG) and estrone (E1) levels in four Japanese macaque females during the initial 19 weeks of gestation, and total number of mounts observed being received and directed by those females during those weeks.

PdG and E1 levels showed fluctuations in the initial 100 days of gestation. PdG concentrations rose steadily from the time of conception to approximately the 5th week of gestation, followed by a drop in concentration and low levels between weeks 6 and 14, after which PdG levels continue to increase steadily toward term. Although E1 levels followed a similar pattern as that of PdG, the changes in concentration were not as marked during the temporary decline in the 6th to 12th week. This pattern of hormone fluctuations throughout pregnancy is similar to findings on other macaque species (Macaca mulatta: Wilson et al., 1982; Macaca fasicularis: Stabenfelt & Hendrikx, 1973; Macaca radiata: Stabenfelt & Hendrikx, 1972).

We found an association between dropping PdG levels during gestation and the rate of mounting. Decreases in PdG levels during gestation may allow for the expression of proceptivity in females, similar to the effects of decreased PdG levels during the follicular and periovulatory phases of the cycle (O’Neill et al., 2004b).

The majority of post-conceptive mating occurred during weeks 6-11 of gestation, during the period of low PdG levels, as has been previously reported for rhesus monkeys (Bielert et al., 1976) and Hanuman langurs (Sommer, 1993). Although the sample is small, it is worth noting that, while most heterosexual mating activity occurred during weeks 6 and 7, same-sex mating took place in weeks 8 to 11.

The ovary is essential for the production of progestins and estrogens during the first few weeks of gestation, after which the placenta assumes the production of these hormones. Our finding of an increase in PdG and E1 between the 3rd and 5th week of gestation may represent a temporary dual production of these hormones by both the ovaries and the placenta. The subsequent drop in hormones between weeks 6 and 12 may represent a loss of the ovaries’ contribution, while the placenta attempts to take its place in the production of progestins and estrogens. Both PdG and E1 levels then begin to recover and continue to rise.

In terms of a proximate explanation for the widely reported pattern of post-conceptive mating in Japanese macaques, we suggest that the temporary drop in PdG levels during the 6th and 11th weeks of gestation may facilitate a false “estrus” or period of proceptivity and attractivity in the pregnant female. Furthermore, if post-conceptive mating does encourage males to behave more tolerantly toward pregnant females and their subsequent infants, then a hormonally-induced period of proceptivity/attractivity during gestation may also be selectively advantageous. More data are required to determine whether a peak in mating activity between weeks 6 and 10 is prevalent in this and other Old World monkey species.

USDA Inspection Process Changes Can Be Expected

Research facilities may see some changes in their next U.S. Department of Agriculture inspection. Prompted by the Audit Report of Animal Welfare Act (AWA) enforcement issued last fall by the USDA Office of Inspector General (OIG), the Animal & Plant Health Inspection Service (APHIS) is modifying some of its policies and procedures or is clarifying existing requirements. USDA inspectors have been instructed to do the following: Beyond the administrative changes above, APHIS has agreed to propose several revisions to current regulations. As recommended by the OIG, research facilities could be required to identify the number of protocols as well as animals in each pain relief category of their annual reports. IACUCs might be asked to conduct more frequent reviews of facilities deemed to be repeat violators. Also, the OIG directed APHIS to provide a plan for increasing fines imposed on research facilities for violations, a step that necessitates amending the AWA. The National Association for Biomedical Research (NABR) will monitor any regulatory or legislative changes that may be proposed.

If you have questions, comments or concerns, please contact NABR [e-mail: [email protected]]. NABR is interested in hearing about USDA inspection experiences so that staff will understand members’ needs and can better advise others about AWA compliance, as well as represent research interests to regulators. As NABR goes about doing its job, individual research facilities are never identified without expressed permission.

Finding New Homes for Ex-Laboratory and Surplus Zoo Primates

Mark J. Prescott
Primate Society of Great Britain (PSGB) Captive Care Working Party (1)


This article is written to assist organizations which may be considering “rehoming” primates and draws upon the experience of members of the Primate Society of Great Britain (PSGB) Captive Care Working Party.

Rehoming ex-laboratory and surplus zoo primates is not a new concept. A number of New World and Old World monkey and ape species have been successfully rehomed to reputable sanctuaries in Europe and the U.S.A., allowing the animals to live out the remainder of their lives relatively free of human disturbance. Rehoming has been found to benefit the morale of staff members involved with caring for the animals and can help further develop a culture of care. However, the rehoming process can entail welfare costs to the animals involved, depending on, for example, their ages and state of health, the circumstances and duration of transport to the new site, and the physical and social conditions in which the animals will be kept. Primates should thus only be rehomed if it is clear that the process will be truly in the best interests of the individual animals, that it will not harm their welfare, and that the new home offers a good quality of life.

Rehoming and laboratories: Every year around 65,000 primates are used in European and U.S. laboratories, mainly for pharmaceutical safety and efficacy evaluation and research in the fields of microbiology, neuroscience, and biochemistry/chemistry (Carlsson et al., 2004; European Commission, 2005; United States Department of Agriculture, 2004). The majority of these animals are euthanized as an integral part of the experimental procedures. In situations where this is not required, or in the case of former breeding or surplus stock animals, it may be possible to rehome the animals as an alternative. Legitimate sanctuaries will accept ex-laboratory primates but registered zoos tend not to do so because, with the exception of the chimpanzee (Pan troglodytes) and cotton-top tamarin (Saguinus oedipus), species commonly used in biomedical research and testing (see Conlee et al., 2004; European Commission, 2002) are not priority species for captive breeding for conservation (2).

Rehoming and zoos: Rehoming is also an option for surplus zoo primates no longer capable of being housed at the zoo because of limited space and resources and for which alternative zoo accommodation cannot be found. Surplus animals are those not suitable for breeding because of their pedigree (e.g., over-representation of the bloodline), quality (e.g., poor breeding performance), age (e.g., no longer reproductively viable), or sex (e.g., bachelor males of polygynous species), and hence not needed for the survival of the captive population. Such animals are an inevitable product of captive breeding programs, even where breeding opportunities are carefully controlled through studbooks and effective birth control. Euthanasia of healthy surplus zoo animals to increase available space and the viability of captive populations is justifiable in some cases but is extremely controversial, especially when the individuals involved are of an endangered species. Rehoming to a sanctuary with high standards of animal welfare is a potential solution to this complex problem.

The relocation of surplus zoo animals for use in experimental procedures is generally discouraged because of adverse welfare effects associated with the change from the zoo to the laboratory environment. However, this might be considered acceptable if it can be guaranteed that the animal can be used in a terminal procedure within a short time, and that this could potentially make unnecessary the breeding or capture from the wild of another animal specifically for that purpose (Graham 1996) (3).

Guidance on the Rehoming Process

Rehoming and relocating primates is not something that can be done lightly, both because of the nature of the animals and because of the need to find facilities that can properly accommodate and look after them in the long term. Careful and timely planning of the whole process is critically important (Brent, 2004; Seelig & Truitt, 1999). Any organization setting out to rehome animals should, therefore, have a clearly defined and documented procedure in place which enables all issues relating to animal welfare, health, and safety, the prospective owner, and any participating organizations, to be addressed. The factors that must be considered include:

Selection of suitable animals: Clearly, animals should only be rehomed if they are not suffering or likely to suffer any adverse effects from their experiences in the laboratory or zoo environment (4). In the case of ex-laboratory primates, there must be careful consideration of any experimental work that has taken place with the animal, and any long-term effects that this may have. It is important to assess any health issues that the experimental work or life in the zoo may have raised and the background health status of the animal. These may affect the likelihood of rehoming, since sanctuaries are obviously reluctant to introduce new transmissible diseases into their colonies, as well as future care and husbandry. The behavioral health, social experience, and character of the individual animals, and whether they are likely to be able to cope in a new environment, should also be considered. In addition, serious thought should be given to permanent sterilization of any animals chosen for rehoming.

Preparation of animals: Rehoming primates usually results in a change of conspecifics, and will certainly involve new human contacts and a different physical environment, all of which may have behavioral consequences for the animals. These must be addressed if rehoming is to be a positive experience. It is important to consider whether each individual animal can learn to cope with a change in what is “normal” in his or her environment. The “normal” environment for a laboratory primate is relatively constant and constrained, and often exclusively indoor. It may offer primate companionship but limited human interaction. In contrast, the environment of a primate in a zoo or sanctuary may be more spacious, complex, and varied, with outdoor and indoor elements, and a variety of experiences with humans. It is therefore vital to have a preparatory phase in any rehoming scheme. Although this could take place immediately prior to release, once rehoming is accepted as a potential option, there is much that can be done within the routine management of both breeding and experimental animals to begin preparation for future potential rehoming. For example, the animals can be socialized to other primates and to humans of either sex and varying appearance, habituated to a transport box, and trained to station (i.e. stay at a particular location) using positive reinforcement techniques (Prescott & Buchanan-Smith, 2003; Prescott et al., 2005a, 2005b). Such activities will assist with capture, transport, and health inspection in the new home. Furthermore, programs of socialization, habituation and training not only make the animals more suitable for rehoming, but also benefit both science and animal welfare, since they lower the animals’ stress levels when faced with novel or stressful situations in the laboratory or zoo environment, such as strange humans or scientific, veterinary, or husbandry procedures (e.g. Bassett et al., 2003; Savastano et al., 2003). Ethological or animal training advice should be sought from specialists for the design of such programs.

In view of their highly social nature, primates should never be rehomed alone or into homes without compatible companions of the same species. Formation of compatible pairs or groups prior to rehoming will facilitate integration into the new social group. For advice on animal introductions see Watts & Meder, 1996.

Transport can be a stressful experience for primates (e.g. Honess et al., 2004, 2005; Prescott & Jennings, 2004; Wolfensohn, 1997). It is important, therefore, to use a reputable transport company and to take all steps necessary to ensure their safe arrival in good health and with minimal distress. For guidance on transporting primates, see Swallow et al., 2005. It is recommended that a familiar caregiver be present on the day of introduction of the animals to their new environment and social companions, in order to provide continuity and deal with any potential problems. Maximizing the degree of visual and olfactory familiarity by passing on pen furniture and toys when relocating animals, and ensuring a gradual change in diet, is also likely to be beneficial.

Assessing the suitability of a new home: As with any animal rehoming program, proper matching of the retired primate/s with the new home and prospective owners is a basic condition for success. Primates should only be rehomed to the care of professional and experienced primate keepers (i.e.., from reputable sanctuaries and registered/accredited zoos (5) or laboratory breeding establishments). With few exceptions, private individuals should be considered unacceptable as new owners of primates (6). Ideally, the prospective owners should have a recommendation from the relevant committee of a professional primatological society (e.g., Captive Care Working Party of the PSGB or Captive Care Committee of the International Primatological Society) or zoo association, or from an animal welfare organization that already rehomes primates (e.g., U.K.’s Royal Society for the Prevention of Cruelty to Animals, or the International Primate Protection League).

It is essential to visit prospective homes to check that they can provide a suitably high standard of accommodation and care (e.g. spacious and enriched enclosures, designed with the animals’ needs in mind; trained and competent staff and volunteers), that they have good background knowledge of the species and its requirements (e.g. Prescott & Buchanan-Smith, 2004), and that the facilities are secure. Make sure that the prospective owners have any necessary licenses (7), have access to veterinary advice, and can catch the animals if they require treatment. Be aware that identifying, researching, and evaluating candidate homes for the animals can take some time.

Primates have long life spans and prospective new homes may be taking responsibility for many years of the animals’ lives, and will also have to make decisions about euthanasia at the end of those lives. It is vital, therefore, to confirm that prospective owners are genuine (e.g., not animal dealers who intend to breed or sell the animals, or give them to a friend), that they intend to care for the animals in the long term, and that they have the financial security to do so. Reputable zoos and sanctuaries know their own limits and usually will not accept animals that they cannot care for; they will also prevent them from breeding. For further useful criteria for distinguishing true sanctuaries from “pseudo-sanctuaries”, see Seelig & Truitt, 1999.

Establishments receiving ex-laboratory primates need to be chosen with care as, in some instances, they have portrayed the animals as being “rescued” from the laboratory. This situation can be avoided by ensuring that the receiving establishment and any intermediaries participate in the right spirit, with full knowledge of the reasons for the animals’ past use, and that they agree on any public statements that will be made prior to receipt of the animals. Involving primatological societies and animal welfare organizations (as above) will also help in this respect.

Follow-up: Primates may take some time to adjust to their new environment. In view of this, it is important to follow up on animals once they have been placed in their new home, to ensure that their welfare is not compromised and that the rehoming process is successful. Provide contact telephone numbers to the new owners for advice (e.g., a named person under the U.K. Animals [Scientific Procedures] Act 1986 or senior zoo keeper, plus a veterinary practitioner experienced with primates), and request that the new owners give updates of the animals’ progress, since this will help determine whether the process itself is successful, as well as whether it is successful for individual animals. It is advisable to undertake behavioral studies to assess how well the animals are settling into their new homes. The output from such follow-up studies should be used to review and improve socialization, habituation, and training programs to facilitate safe and humane rehoming in the future.

More Fun with a Barrel Full of Monkeys: A Nonhuman Primate Swing Made by Recycling Plastic Barrels

Ernie Davis

National Institutes of Health

Providing a suitable living environment for many species of socially housed nonhuman primates can be both challenging and expensive, requiring institutions to be innovative and resourceful when devising their enrichment programs. Development, encouragement, and enhancement of species-typical behaviors should be the primary objectives when designing these man-made environments. One innovative way to enhance these behaviors is to incorporate them into the structural setting, since structures and furnishings are vital components of any captive living environment. Structures not only increase the usable cage volume; they also provide animals with greater enrichment opportunities by engaging them in many types of species-typical activities.

The NIH Shared Animal Facilities’ enrichment program has developed a primate swing created from recycling our discarded plastic 30- and 55-gallon detergent barrels. These swings are easy to construct and are effective in increasing our animals’ behavioral repertoires. Additionally, these swings are safe, portable, non-toxic, easy to sanitize, and almost indestructible. We have used these barrels in our socially-housed monkey runs for over three years, and they are still going strong!

Tool list and other equipment needed:

  1. Barrel
  2. Power drill and drill bits
  3. Jig saw
  4. Marking pen
  5. Tape measure
  6. 3/8” eye bolt, 3” long, and 9/16” nut
  7. Length of chain, 3/8 to 5/8” thick
  8. Snap hook
  9. Hole saw, 1” diameter
  10. Piece of 1”-thick x 5”- or 6”-wide x 12” long plastic floor decking (can be bought at home improvement centers or ordered online)
  11. Screws – Philips Pan A Tapping #10, 1 1/4” long
Note: Before starting your project, wash and rinse your barrel thoroughly both inside and out to remove leftover detergent residue.


To start your project, select a 30- or 55-gallon plastic barrel.


Note that on the barrel’s outer surface there is a seam running vertically along the entire length of the barrel on both sides. This seam was produced during the barrel’s molding process. You can use this seam as a guide or reference point to find the vertical center of your barrel.


Follow this center seam to the top of your barrel. The “top” of your barrel, for construction purposes, will now be designated as the “bottom” of your swing.


To start construction, follow the vertical center seam to the designated bottom of your swing where the barrel starts tapering inwardly.


At this junction measure outward 8” on each side of the center seam and make a mark with your pen. Once marked, this will give you a total span of 16” in width.

Then go to the opposite side of the barrel and mark out the same measurements at the same location. After this is completed both sides should look identical and be opposite from one another.


Once these bottom marks are established you will need to follow the center seam past one horizontal reinforcement band, to the second band from the bottom.


At this junction and again centered on the vertical seam, measure and mark out 3” on each side of the center seam. This will give you a span of 6”. This area will become the top portion of your swing. Repeat on the opposite side.


Now, on each side of the barrel, join all lines together with a straight edge as illustrated in the photo.


Next, cut your swing out as illustrated, leaving the lines intact.


The next part of your production process is to fasten the Decking Board to the top of your swing. This is done by fastening screws to the top end of your swing and to the edges of the decking board as shown in the photo.

drainage holes

Next, with a one-inch hole saw, cut drainage holes into the bottom of your barrel


The last step in completing this project is to attach your chain and eye bolt to the top of your swing.

Using Recycled Barrel Swings vs. Prima-Hedrons in Primate Enclosures

Kimran E. Miller, Katalin Laszlo, and S. J. Suomi

National Institutes of Health

To document the utility of using recycled barrel swings vs. Prima-Hedronsâ as enrichment objects, we observed a socially housed group of 28 tufted capuchins (Cebus apella) at the NIH Shared Animal Facility in Poolesville, Maryland. Their indoor enclosure included five Prima-Hedrons and two recycled barrels, among other objects including fixed perches, on which the capuchins could locomote or engage in stationary behaviors.

Figure 1: Prima-Hedrons.

The Prima-Hedrons and barrels were of a similar size. We collected data on the location of the focal animal within the enclosure every 30 seconds during 5-minute focal observations on each animal per day (October 2004 to May 2005, n = 70 days). We calculated frequencies of object use by dividing the number of times an animal was located on an object by the total number of location data points collected for that animal.

We calculated an average frequency of use for Prima-Hedrons and for barrels, for each animal. We found no significant difference in the average frequency of use of hanging Prima-Hedrons vs. hanging barrels (Wilcoxon matched pairs test, n=28, W=73.0, p=0.12). Our results indicate that recycled barrels may be used as a viable alternative to Prima-Hedrons for enriching enclosure use.

Is a Swimming Pool Safe for Macaques? A Discussion

The following discussion took place on the Laboratory Animal Refinement & Enrichment Forum (LAREF) among Heather Kirby [e-mail: [email protected]], Wake Forest University; Jill Rawlins [[email protected]], Oregon Primate Research Center; Polly Schultz [[email protected]], Wisconsin Primate Research Center; and Natasha Down [[email protected]], York University. The posted contributions have been edited by Viktor Reinhardt [[email protected]], moderator of the forum.

Kirby: “The center where I work has several long-tailed macaque breeding colonies housed in large outdoor enclosures. I am interested in using stock tanks to provide foraging opportunities in the winter and swimming opportunities in the summer. I have heard that cynos are adept swimmers, but is there is a risk of drowning, particularly for infants? Is there danger of one monkey inadvertently drowning another monkey?”

Rawlins: “The stock tanks we use have a lip half way up the inside of the tank, so if an infant would fall into the water it could easily get back out. We used these tanks all of last summer and half of the summer before and never encountered any problem. The monkeys who do go under water hold their breath for a surprisingly long time.”

Schultz: “I have watched juvenile cynos three months old and older swim with no difficulty. I have never come across one who can’t swim. It seems to be a very natural, instinctive skill for them that they do not have to learn. The only time we had a problem — or let’s say ‘near problem’ — was when an adult female was swimming underwater, and a big male was playing around, like a cat chasing after a mouse, from outside of the pool, and finally jumped on her back. He put his hands around her neck and appeared to be deliberately holding her under in the 3-feet-deep water. After about 15 seconds I panicked, as I thought he was actually drowning her. I rushed to the scene to ‘interfere’, but just at that point he released her and retreated. She shot out of the water like a rocket and was REALLY angry with him, screeching and with rage in her eyes. He looked surprised, and as if he had made a significant error, ran screaming away from her as she chased him down and bit him a good one and repeatedly slapped and pinched him. The whole time he was acting submissively toward her, lip smacking wildly, and ducking as she continued to clobber him.

“The two have been in the pool together many times since then, but the female never takes her eye off the male even when she’s under water (as cynos dive with their eyes open).

“With regard to infants I would perhaps be concerned with a tank if there is not a really easy way for them to crawl out. I would place PVC tubing arranged like branches of a submerged tree sticking out of the water and providing a bridge between water and the safe rim of the pool.

“Macaques not only enjoy being in water but also playing with water (Figure 1).”

Figure 1: Playing on the “bathtub”.

Down: “We used to give two pair-housed rhesus girls a ‘bathtub’ on Fridays. The tub was simply a rat cage filled with water placed in the tunnel of the two interconnected cages (Figure 2). Tejas would go under water and keep her eyes open. The other girl, Kuaui, would dive with her eyes and mouth open! Since the rat cage was transparent, I could see everything. The two were quite hilarious! I am surprised they could fit themselves into the ‘bathtub’ but they loved it! Tejas once held her breath while under water for 15 seconds. This is quite impressive, as they were both scared of the tub when I very first introduced it!”

Donations Sought for Sylvia Taylor Memorial Session

As announced in the April, 2006, issue of the LPN, on August 14, 2006, as part of its annual meeting, the Animal Behavior Society (ABS) will host a special session, called “Primate Behavior Studies: Essential to Primate Welfare,” to explore the relationship between a knowledge of primate behavior and the ability to provide for the welfare of primates, both in the wild and in captivity. This session will be held in memory of Dr. Sylvia Taylor, an active ABS member and the primate field specialist for the USDA, APHIS (Animal Care), at the time of her unexpected death in 2005.

While the Animal Behavior Society will be hosting this special session, it will not be providing any additional funding to underwrite the appearance of the speakers. Therefore, donations are needed to ensure that the speakers will be available to make their planned presentations. Organizations or individuals willing to sponsor one or more speakers may do so for a donation of $1,000 per speaker, and their sponsorship will be recognized during the introduction of the speaker(s). It is hoped that the proceedings of this session will be published, and it is planned to recognize all donors if such proceedings do become available, unless a donor wishes to remain anonymous.

The speakers will be (tentatively, at this time) Sue Savage-Rumbaugh, David Seelig, Gail Laule, Steve Schapiro, Kate Baker, Linda Brent, Terry Maple, and Elizabeth Lonsdorf.

Any funds collected in excess of the expenses of producing the special session and the proceedings will be used to fund a research grant in Dr. Taylor’s honor. Donations may be may be made online at <> or mailed to The Sylvia Taylor Memorial Fund, Animal Behavior Society, 2611 East 10th St, Bloomington IN 47408-2603.

Proposed Amendment to Animal Welfare Act

On April 28, USDA’s APHIS announced a request for comments, due June 26, 2006, on a proposed rule that would amend Animal Welfare Act regulations requiring the use of shift cages for moving and transporting potentially dangerous animals, including nonhuman primates and other species. This proposed rule would require the use of shift cages for gorillas, chimpanzees, orangutans and “other nonhuman primates”. There is concern about how this rule would affect the research community. The proposed rule is located in the Federal Register Vol. 71, No. 82, Friday, April 28, 2006, 9 CFR Part 2, APHIS Docket No. APHIS-2005-0118.

News Briefs

Orangutan, 44, dies at St. Louis Zoo

Junior, patriarch of the St. Louis Zoo’s orangutan family, was euthanized Tuesday after a long struggle with arthritis. Junior was an estimated 44 years old and was one of the oldest male orangutans living in captivity. Zoo veterinarians had been treating Junior with anti-inflammatory and anti-pain medications for three years. Recently, however, Junior showed a reluctance to eat, move, or play with his two-year old daughter Rubih, once a favorite activity.

Sumatran orangutans like Junior are critically endangered. In the past decade, the wild population has been cut in half to 5,000 animals. – By Diane Toroian Keaggy, St. Louis Post-Dispatch, March 29

DRC Entrusts Two Reserves to Communities

KINSHASA, Democratic Republic of Congo, April 10, 2006 (ENS) – Legally recognized community conservation took a big step forward in the Democratic Republic of Congo last week when the government handed the care and control of two large nature reserves over to local community groups. Adjacent to each other, the reserves form a globally important biodiversity site inhabited by endangered Grauer’s gorillas, eastern chimpanzees, forest elephants, and okapi.

DRC Minister of Environment Anselme Enerunga signed two new decrees that legally gazette two large nature reserves, the Tayna Nature Reserve, 900 square kilometers, and the Kisimba-Ikobo Nature Reserve, 1,370 square kilometers. Enerunga says DRC plans to increase the amount of its forested protected areas to 15 percent of the total national area. Currently, about eight percent of the country is protected. The two decrees will be accompanied by contracts in which complete management and responsibility for protecting the two reserves is ceded by the government to the local people. Local people acting as eco-rangers can be deputized by the government to bear arms to protect against poaching and the illegal wildlife trade. – © Environment News Service, 2006

Monkeys Ruin Crops in Puerto Rico

A group of angry farmers gathered in the small town of Cabo Rojo, Puerto Rico, to talk about this year’s crops and, surprisingly, none is worried about drought or wildfires that ruined thousands of acres of last year. Rather, the farmers are worried about a much different menace –one that has laid waste to far more crops in recent years than any disease, drought or other natural disaster. The threat comes from hordes of feral monkeys –sometimes descending into fields in groups of 20 or more – that ruin thousands of acres of squash, melons and other produce.

In reaction, farmers are taking matters into their own hands and shooting the wild monkeys. That move comes weeks after the island’s Department of Natural and Environmental Resources (DNER) announced that a continuing financial crisis in San Juan made it impossible to fund a program to trap the monkeys and sell them for medical research.

“What farmers do on their own lands in their business,” said Marcos Irizarry, a squash farmer and mayor of the nearby village of Lajas. “All Puerto Rico’s government wants to do about these monkeys is talk about them,” he said. “That’s not doing anyone any good. The problem is out of control.”

Irizarry said the estimated 2,000 monkeys in southwest Puerto Rico are descendants of patas and rhesus monkeys that escaped from a nearby medical research laboratory during the 1950s and 1960s. Around that time, more than 100 monkeys were released on a tiny island in the Boqueron Forest, about a quarter-mile offshore. In the 1960s, Lajas residents told authorities about clans of monkeys entering their yards, raiding their fruit trees and even throwing large ripe fruits at dogs and other animals.

DNER officials say the monkeys should not be thought of animals that might one day be domesticated. These monkeys, officials said, are “wild animals that carry diseases and could bite.” “We urge people to stay away from them,” said Ernesto Diaz, a top administrator in the department’s San Juan office. – By Ray Quintanilla, Tribune staff reporter, April 11, 2006, © Chicago Tribune

Monkey Menace in Kendrapara, India

Kendrapara district administration has shot off an SOS to the state forest department pleading for an early end to the ongoing man-monkey conflict. The administration is worried over the growing nuisance of monkeys, leaving at least one dead and more than 200 persons injured in the last month. An assistant conservator of forest is scheduled to visit the area to assess the gravity of the situation. Later the forest department plan to find ways and means to get rid of the menace.

An infant was picked up by a male monkey and later thrown from the housetop, killing the child instantly. The monkeys, who have lately turned violent, have targeted school children, snatching edibles from the children during recess hours. Last week more than a dozen children were bitten by monkeys in two government-run primary schools in the township.

Apart from trampling crop and vegetable fields beyond redemption, the monkeys have also not spared the government offices, ransacking valuable documents.

The monkey nuisance had hogged the spotlight in 2002, when classes of a college in Tirtol area had to be suspended following a week-long spell of violence by the animals. A male monkey atop a banyan tree inside the college campus had injured more than 50 college students. That had led to thin attendance, prompting the college authorities to suspend classes.

Animal researchers believe that this behavioral change can be traced back to the loss of monkeys’ habitat and food, starting in 1999 when a cyclone caused heavy damage to trees. – Statesman News Service, April 12

Second Ohio State Chimp Dies at Texas Sanctuary

A second chimpanzee, who had been moved to a Texas animal sanctuary after Ohio State University decided to close a research center, has died, the University said April 21. The 16-year-old male, named Bobby, was found dead in his enclosure April 20. No cause of death was immediately determined.

Caretakers noticed Bobby seemed unwell April 19 and had scheduled a visit with a veterinarian for the next day, the university said. The remaining chimpanzees appear to be healthy.

Dr. Sally Boysen, the Ohio State psychology professor who had worked with the chimps for decades, has sued the university, saying the refuge is unsafe and is trying to get the animals sent elsewhere. – Akron Beacon Journal, April 24

Chimps Kill Tour Driver, Escape from Sanctuary

A group of chimpanzees attacked and killed a Sierra Leonean driver and seriously injured two American visitors and one Canadian at a wildlife sanctuary on Sunday, a police spokesman said. The attack occurred at the Tacugama Chimpanzee Sanctuary on the outskirts of this capital. The center, set up in 1995 to give shelter to orphaned and abandoned chimpanzees, houses nearly 70 primates in a semiwild environment. The police said a large group of chimpanzees suddenly turned on the four, biting and tearing at their clothes. The driver was employed by the reserve. The injured survivors, employees of a construction company in Sierra Leone, were taken to a hospital. – Reuters, April 24, 2006

Thirty-two chimps escaped, but they gradually came closer, and most returned, by ones and twos. By the end of April, there were 14 chimpanzees – 12 adults and two infants – still out in the forest. Police and law enforcement followed orders not to shoot any chimpanzees or other wildlife. “The support the Government of Sierra Leone has shown during this crisis is extremely encouraging,” said Tacugama founder Bala Amaresekaran. Following the escape, villagers in the surrounding area were given telephone contact numbers for Tacugama and asked to call the staff if they spotted any chimpanzees.

Amarasekaran said that he was surprised and encouraged by how quickly the sanctuary chimpanzees adapted to life in the forest – including the ability to find food and shelter – especially given how physically and emotionally damaged many of them were upon arrival at Tacugama. Nevertheless, the goal is return all of the escaped chimpanzees to the sanctuary.

As this issue of the LPN is going to press, there are six chimpanzees, including one infant, still in the forest.

Monkeys destroy crops in Tanzania

Thousands of monkeys are wreaking havoc on Tumbatu, an island in Tanzania’s Zanzibar archipelago, where locals have appealed for help to exterminate the simians, officials said. Increasingly, colobus monkeys are destroying farmers’ crops on the islet just north of Zanzibar’s main island of Unguja in the Indian Ocean, they said.

“Some farmers have been spending nights in their fields to protect crops from being eaten or destroyed by the monkeys,” said Zanzibar north regional commissioner Pembe Juma. “We have been providing tools to kill the monkeys, but still there are many continuing to destroy farm produce,” he said. – Sapa-Agence France-Presse June 1

Anatomy and Physiology

* Twenty-four-hour rhythmic gene expression in the rhesus macaque adrenal gland. Lemos, D. R., Downs, J. L., & Urbanski, H. F. (H. F. U., Div. of Neuroscience, Oregon NPRC, 505 Northwest 185th Ave, Beaverton, Oregon 97006 [e-mail: [email protected]]). Molecular Endocrinology, 2006, 20, 1164-1176.
. . . “The suprachiasmatic nucleus plays a key role in the circadian secretion of adrenocortical hormones. However, there is evidence from mouse studies that components of the circadian clock are also expressed within the adrenal gland itself. In the present study we performed genome-wide expression profiling to determine whether the adrenal gland of rhesus monkeys shows temporal gene expression across a 24-h period. We identified 322 transcripts with rhythmic patterns of expression and found that the phase distribution of cycling transcripts varied across the day, with more genes showing activation during the night. We classified the transcripts by their function and clustered them according to their participation in common bio-chemical pathways: 1) catecholamine synthesis and reuptake; 2) cholesterol cleavage and dehydroepiandrosterone sulfate synthesis; 3) protein synthesis and turnover; and 4) the circadian clock mechanism. In an additional experiment, we assessed the expression of various clock genes at two time points, 12 h apart. We found that expression of Bmal1 and Cry1 was higher at 1300 h, or zeitgeber time 6, whereas expression of Per1 was higher at 0100 h (zeitgeber time 18). Expression levels of Rev-erbα were higher at 0100 h than at 1300 h (P < 0.05), and immunohistochemistry revealed a strong expression of this transcription factor specifically in chromaffin cells of the adrenal medulla. Taken together, the data indicate that the primate adrenal gland shows rhythmic expression of genes associated with cell biology and synthesis of steroids and catecholamines. Moreover, they strongly imply the existence of an intrinsic circadian clock.”

Animal Models

* Comparative analysis of cancer genes in the human and chimpanzee genomes. Puente, X. S., Velasco, G., Gutiérrez-Fernández, A., Bertranpetit, J., King, M.-C., & López-Otín, C. [Depto de Bioquímica y Biología Molecular, Fac. de Med., Inst. Univ. de Oncología, Univ. de Oviedo, 33006-Oviedo, Spain [e-mail: [email protected]]). BMC Genomics, 2006, 7-15.
. . . “Cancer is a major medical problem in modern societies. However, the incidence of this disease in nonhuman primates is very low. To study whether genetic differences between human and chimpanzee could contribute to their distinct cancer susceptibility, we have examined in the chimpanzee genome the orthologous genes of a set of 333 human cancer genes. This analysis has revealed that all examined human cancer genes are present in chimpanzee, contain intact open reading frames and show a high degree of conservation between both species. However, detailed analysis of this set of genes has shown some differences in genes of special relevance for human cancer. Thus, the chimpanzee gene encoding p53 contains a Pro residue at codon 72, while this codon is polymorphic in humans and can code for Arg or Pro, generating isoforms with different ability to induce apoptosis or interact with p73. Moreover, sequencing of the BRCA1 gene has shown an 8 Kb deletion in the chimpanzee sequence that prematurely truncates the co-regulated NBR2 gene. These data suggest that small differences in cancer genes, as those found in tumor suppressor genes, might influence the differences in cancer susceptibility between human and chimpanzee. Nevertheless, further analysis will be required to determine the exact contribution of the genetic changes identified in this study to the different cancer incidence in nonhuman primates.”

* Cynomolgus macaque as an animal model for severe acute respiratory syndrome. Lawler, J. V., Endy, T. P., Hensley, L. E., Garrison, A., Fritz, E. A., Lesar, M., Baric, R. S., Kulesh, D. A., Norwood, D. A., Wasieloski, L. P., Ulrich, M. P., Slezak, T. R., Vitalis, E., Huggins, J. W., Jahrling, P. B., & Paragas, J. (J. P., Virology Div., USAMRIID, Fort Detrick, MD [e-mail: [email protected]]). PLoS Med, 2006, 3[5]: e149.
. . . “The emergence of severe acute respiratory syndrome (SARS) in 2002 and 2003 affected global health and caused major economic disruption. Adequate animal models are required to study the underlying pathogenesis of SARS-associated coronavirus (SARS-CoV) infection and to develop effective vaccines and therapeutics. We report the first findings of measurable clinical disease in nonhuman primates (NHPs) infected with SARS-CoV.”

* Postexposure protection against Marburg haemorrhagic fever with recombinant vesicular stomatitis virus vectors in non-human primates: An efficacy assessment. Daddario-DiCaprio, K. M., Geisbert, T. W., Ströher, U., Geisbert, J. B., Grolla, A., Fritz, E. A., Fernando, L., Kagan, E., Jahrling, P. B., Hensley, L. E., Jones, S. M., & Feldmann, H. (T. W. G., USAMRIID, Fort Detrick, MD 21702 [e-mail: [email protected]]). The Lancet, 2006, 367, 1373-1374.
. . . “Effective countermeasures are urgently needed to prevent and treat infections caused by highly pathogenic and biological threat agents such as Marburg virus (MARV). We aimed to test the efficacy of a replication-competent vaccine based on attenuated recombinant vesicular stomatitis virus (rVSV), as a postexposure treatment for MARV haemorrhagic fever. We used a rhesus macaque model of MARV haemorrhagic fever that produced 100% lethality. We administered rVSV vectors expressing the MARV Musoke strain glycoprotein to five macaques 20-30 min after a high-dose lethal injection of homologous MARV. Three animals were MARV-positive controls and received non-specific rVSV vectors. We tested for viraemia, undertook analyses for haematology and serum biochemistry, and measured humoral and cellular immune responses. All five rhesus monkeys that were treated with the rVSV MARV vectors as a postexposure treatment survived a high-dose lethal challenge of MARV for at least 80 days. None of these five animals developed clinical symptoms consistent with MARV haemorrhagic fever. All the control animals developed fulminant disease and succumbed to the MARV challenge by day 12. MARV disease in the controls was indicated by: high titres of MARV (103–105 plaque-forming units per mL); development of leucocytosis with concurrent neutrophilia at end-stage disease; and possible damage to the liver, kidney, and pancreas. Postexposure protection against MARV in non-human primates provides a paradigm for the treatment of MARV haemorrhagic fever. Indeed, these data suggest that rVSV-based filoviral vaccines might not only have potential as preventive vaccines, but also could be equally useful for post-exposure treatment of filoviral infections.”

* RNAi-mediated gene silencing in non-human primates. Zimmermann, T. S., Lee, A. C. H., Akinc, A., Bramlage, B., Bumcrot, D., Fedoruk, M. N., Harborth, J., Heyes, J. A., Jeffs, L. B., John, M., Judge, A. D., Lam, K., McClintock, K., Nechev, L. V., Palmer, L. R., Racie, T., Röhl, I., Seiffert, S., Shanmugam, S., Sood, V., Soutschek, J., Toudjarska, I., Wheat, A. J., Yaworski, E., Zedalis, W., Koteliansky, V., Manoharan, M., Vornlocher, H.-P., & MacLachlan, I. (Alnylam Pharmaceuticals Inc., 300 Third St, Cambridge, MA 02142 [e-mail: [email protected]]). Nature, 2006, 441, 111-114.
. . . “The opportunity to harness the RNA interference (RNAi) pathway to silence disease-causing genes holds great promise for the development of therapeutics directed against targets that are otherwise not addressable with cur-rent medicines. Although there are numerous examples of in vivo silencing of target genes after local delivery of small interfering RNAs (siRNAs), there remain only a few reports of RNAi-mediated silencing in response to systemic delivery of siRNA, and there are no reports of systemic efficacy in non-rodent species. Here we show that siRNAs, when delivered systemically in a liposomal formulation, can silence the disease target apolipoprotein B (ApoB) in non-human primates. APOB-specific siRNAs were encapsulated in stable nucleic acid lipid particles (SNALP) and administered by intravenous injection to cynomolgus monkeys at doses of 1 or 2.5 mg/kg. A single siRNA injection resulted in dose-dependent silencing of APOB messenger RNA expression in the liver 48 h after administration, with maximal silencing of >90%. This silencing effect occurred as a result of APOB mRNA cleavage at precisely the site predicted for the RNAi mechanism. Significant reductions in ApoB protein, serum cholesterol and low-density lipoprotein levels were observed as early as 24 h after treatment and lasted for 11 days at the highest siRNA dose, thus demonstrating an immediate, potent and lasting biological effect of siRNA treatment. Our findings show clinically relevant RNAi-mediated gene silencing in non-human primates, supporting RNAi therapeutics as a potential new class of drugs.”


* Referential gestural communication in wild chimpanzees (Pan troglodytes). Pika, S., & Mitani, J. (School of Psychology, Univ. of St. Andrews, St. Mary’s Quad, St. Andrews, Fife, KY16 9JP, Scotland, U.K. [e-mail: [email protected]]). Current Biology, 2006, 16, R191-R192.
. . . “Humans commonly use referential gestures, for example pointing, which direct the attention of recipients to particular aspects of the environment. The use of these gestures has been linked with cognitive capacities such as mental state attribution because the recipient must infer the signaler’s meaning. In our closest living relatives, the non-human primates, referential gestures have been reported only in captive chimpanzees interacting with their human experimenters and human-raised or language-trained apes. Here is the first evidence for the widespread use of a referential gesture by wild chimpanzees.”

* Why are some animals so smart? Van Schalk, C. (Anthropological Inst. & Museum, Univ. of Zurich, Switzerland). Scientific American, 2006, 294[4], 64-71.
. . . In this article the author seeks to understand why some animals are smarter than others and studies the orangutans of Sumatra in an attempt to answer that question. It has been discovered that there is never-before-seen tool use among these apes, a sign of intelligence. The author proposes that culture is the key to this activity and that the ability to learn the skills of others by observation is a means by which animals can increase levels of intelligence.

* Wild rhesus monkeys generate causal inferences about possible and impossible physical transformations in the absence of experience. Hauser, M., & Spaulding, B. (Dept of Psych., Harvard Univ., Cambridge, MA 02138 [e-mail: [email protected]]). Proceedings of the National Academy of Sciences, U.S.A., 2006, 103, 7181-7185, <>.
. . . “Human infants and adults generate causal inferences about the physical world from observations of single, novel events, thereby violating Hume’s thesis that spatiotemporal co-occurrence from prior experience drives causal perception in our species. Is this capacity unique or shared with other animals? We address this question by presenting the results of three experiments on free-ranging rhesus monkeys (Macaca mulatta), focusing specifically on their capacity to generate expectations about the nature of completely unfamiliar physical transformations. By using an expectancy violation looking-time method, each experiment presented subjects with either physically possible or impossible transformations of objects (e.g., a knife, as opposed to a glass of water, appears to cut an apple in half). In both experiments, subjects looked longer when the transformation was impossible than when it was possible. Follow-up experiments ruled out that these patterns could be explained by association. These results show that in the absence of training or direct prior experience, rhesus monkeys generate causal inferences from single, novel events, using their knowledge of the physical world to guide such expectations.”

* Language evolution: Semantic combinations in primate calls. Arnold, K., & Zuberbühler, K. (K. Z., Sch. of Psychology, Univ. of St Andrews, St Andrews Fife KY16 9JP, Scotland [e-mail: [email protected]]). Nature, 2006, 441, 303.
. . . “Syntax sets human language apart from other natural communication systems, although its evolutionary origins are obscure. Here we show that free-ranging putty-nosed monkeys (Cercopithecus nictitans) combine two vocalizations into different call sequences that are linked to specific external events, such as the presence of a predator and the imminent movement of the group. Our findings indicate that nonhuman primates can combine calls into higher-order sequences that have a particular meaning.”

* Apes save tools for future use. Mulcahy, N. J., & Call, J. (J. C., Max Planck Inst. for Evolutionary Anthropology, Deutscher Platz 6, D-04103 Leipzig, Germany [e-mail: [email protected]]). Science, 2006, 312, 1038-1040.
. . . Planning for future needs, not just current ones, is one of the most formidable human cognitive achievements. Whether this skill is a uniquely human adaptation is a controversial issue. In one study, bonobos and orangutans selected, transported, and saved appropriate tools above baseline levels to use them 1 hour later (Experiment 1). Experiment 2 extended these results to a 14-hour delay between collecting and using the tools. Experiment 3 showed that seeing the apparatus during tool selection was not necessary to succeed. These findings suggest that the precursor skills for planning for the future evolved in great apes before 14 million years ago, when all extant great ape species shared a common ancestor.

* Prediction of parasite infection dynamics in primate metapopulations based on attributes of forest fragmentation. Gillespie, T. R., & Chapman, C. A. (Program in Ecology & Evolutionary Biology, Univ. of Illinois, Urbana, IL 61802 [e-mail: [email protected]]). Conservation Biology, 2006, 20, 441-448.
. . . “Although the effects of forest fragmentation on species and ecological processes have been the focus of considerable research in conservation biology, our capacity to predict how processes will be altered and which taxonomic or functional groups will be most affected by fragmentation is still poor. This problem is exacerbated by inherent temporal and spatial variability in fragment attributes. To improve our understanding of this interplay, we examined how various fragment attributes affect one potentially important ecological process, parasite infection dynamics, and considered how changes in this process affect host metapopulations. From August 1999 to July 2003 we surveyed red colobus (Piliocolobus tephrosceles) metapopulations inhabiting nine fragments (1.2 to 8.7 ha) in western Uganda to determine the prevalence and richness of strongyle and rhabditoid nematodes, a group of potentially pathogenic gastrointestinal parasites. We used noninvasive fecal flotation and sedimentation (n = 536) to detect parasite eggs, cysts, and larvae in colobus fecal samples. To obtain an index of infection risk, we determined environmental contamination with Oesophagostomum sp., a representative strongyle nematode, in canopy (n = 30) and ground vegetation plots (n = 30). Concurrently, physical (i.e., size, location, and topography) and biological (i.e., tree diversity, tree density, stump density, and colobine density) attributes were quantified for each fragment. Interfragment comparisons of nine potential factors demonstrated that an index of degradation and human presence (tree stump density) strongly influenced the prevalence of parasitic nematodes. Infection risk was also higher in the fragment with the highest stump density than in the fragment with the lowest stump density. These results demonstrate that host-parasite dynamics can be altered in complex ways by forest fragmentation and that intensity of extraction (e.g., stump density) best explains these changes.”


* Cowpox virus transmission from rats to monkeys, the Netherlands. Bee, M., van Doornum, G., Dorrenstein, G. M., Niesters, H. G. M., Stittelaar, K. J., Wolaters, M. A. B. I., van Bolhuis, H. G. H., & Osterhaus, A. D. M. E. (A. D. M. E. O., Inst. of Virology, Erasmus Univ. Rotterdam, P.O. Box 1738, 3000 DR Rotterdam, Netherlands [e-mail: [email protected]]). Emerging Infectious Diseases, 2006, 12[6], <>.
. . . “We report an outbreak of cowpox virus among monkeys at a sanctuary for exotic animals. Serologic analysis and polymerase chain reaction were performed on blood and swab samples from different rodent species trapped at the sanctuary during the outbreak. Sequence comparison and serologic results showed that brown rats (Rattus norvegicus) transmitted the virus to monkeys.”

Evolution, Genetics, and Taxonomy

* Cranial remains of an Eocene tarsier. Rossie, J. B., Ni, X., & Beard, K. C. (Dept of Anthropology, Stony Brook Univ., Stony Brook, NY [e-mail: [email protected]]). Proceedings of the National Academy of Sciences, U.S.A., 2006, 103, 4381-4385; <>.
. . . The phylogenetic position of tarsiers relative to anthropoids and Paleogene omomyids remains a subject of lively debate that lies at the center of research into anthropoid origins. Omomyids have long been regarded as the nearest relatives of tarsiers, but a sister group relationship between anthropoids and tarsiers has also been proposed. These conflicting phylogenetic reconstructions rely heavily on comparisons of cranial anatomy, but until now, the fossil record of tarsiers has been limited to a single jaw and several isolated teeth. In this article, cranial material of a fossil tarsiid from the middle-Eocene Shanghuang fissure-fillings in southern Jiangsu Province, China, is described. This facial fragment, which is allocated to Tarsius eocaenus, is virtually identical to the corresponding anatomy in living tarsiers and differs substantially from that of early anthropoids such as Bahinia, Phenacopithecus, and Parapithecus. This new specimen indicates that tarsiers already possessed greatly enlarged orbits and a haplorhine oronasal configuration by the time they are first documented in the fossil record during the middle Eocene.

* New primate genus from the Miocene of Argentina. Tejedor, M. F., Tauber, A. A., Rosenberger, A. L., Swisher, C. C., III, & Palacios, M. E. (El CNICT, Lab. de Invest. Evol. y Biodiv., Fac. de Ciencias Naturales, Sede Esquel, Univ. Nac. de la Patagonia “San Juan Bosco”, Sarmiento 849, 9200 Esquel, Argentina [e-mail: [email protected]]). Proceedings of the National Academy of Sciences, U.S.A., 2006, 103, 5437-5441; < /5437>.
. . . “Killikaike blakei is a new genus and species of anthropoid from the late Early Miocene of southeastern Argentina based on the most pristine fossil platyrrhine skull and dentition known so far. It is part of the New World platyrrhine clade (Family Cebidae; Subfamily Cebinae) including modern squirrel (Saimiri) and capuchin monkeys (Cebus) and their fossil relatives known from Early to Middle Miocene and subrecent periods. Living cebines are relatively large-brained, adroit predatory foragers and live within complex social groups, and wild capuchins exhibit a wide range of behaviors associated with enhanced intelligence. We show that K. blakei lacks diagnostic derived characteristics of the lower face and premolar dentition that are shared by modern cebines, but its strongly vaulted frontal bone and capacious anterior cranial fossa indicate the early evolution of an enlarged forebrain.”

* Reactivation by exon shuffling of a conserved HLA-DR3-like pseudogene segment in a New World primate species. Doxiadis, G. G. M., van der Wiel, M. K. H., Brok, H. P. M., de Groot, N. G., Otting, N., t’Hart, B. A., van Rood, J. J., & Bontrop, R. E. (Dept of Comparative Genetics & Refinement, Biomedical Primate Research Centre, P.O. Box 3306, 2280 GH, Rijswijk, Netherlands [e-mail: [email protected]]). Proceedings of the National Academy of Sciences, U.S.A., 2006, 103, 5864-5868; <>.
. . . The common marmoset (Callithrix jacchus), a New World monkey species with a limited MHC class II repertoire, is highly susceptible to certain bacterial infections. Genomic analysis of exon 2 sequences documented the existence of only one DRB region configuration harboring three loci. Two of these loci display moderate levels of allelic polymorphism, whereas the -DRB*W12 gene appears to be monomorphic. This study shows that only the Caja-DRB*W16 and -DRB*W12 loci produce functional transcripts. The Caja-DRB1*03 locus is occupied by a pseudogene, given that most of the transcripts, if detected at all, show imperfections and are present at low levels. Moreover, two hybrid transcripts were identified that feature the evolutionarily conserved peptide-binding motif characteristic for the Caja-DRB1*03 gene. Thus, the severely reduced MHC class II repertoire in common marmosets has been expanded by reactivation of a pseudogene segment as a result of exon shuffling.

* Asa Issie, Aramis and the origin of Australopithecus. White, T. D., Gabriel, G. W., Asfaw, B., Ambrose, S., Beyene, Y., Bernor, R. L., Boisserie, J.-R., Currie, B., Gilbert, H., Haile-Selassie, Y., Hart, W. K., Hlusko, L. J., Howell, F. C., Kono, R. T., Lehmann, T., Louchart, A., Lovejoy, C. O., Renne, P. R., Saegusa, H., Vrba, E. S., Wesselman, H., & Suwa, G. (Dept of Integrative Biology, Univ. of California, Berkeley, CA 94720 [e-mail: [email protected]]). Nature, 2006, 440, 883-889.
. . . “The origin of Australopithecus, the genus widely interpreted as ancestral to Homo, is a central problem in human evolutionary studies. Australopithecus species differ markedly from extant African apes and candidate ancestral hominids such as Ardipithecus, Orrorin and Sahelanthropus. The earliest described Australopithecus species is Au. anamensis, the probable chronospecies ancestor of Au. afarensis. Here we describe newly discovered fossils from the Middle Awash study area that extend the known Au. anamensis range into northeastern Ethiopia. The new fossils are from chronometrically controlled stratigraphic sequences and date to about 4.1 to 4.2 million years ago. They include diagnostic craniodental remains, the largest hominid canine yet recovered, and the earliest Australopithecus femur. These new fossils are sampled from a woodland context. Temporal and anatomical intermediacy between Ar. ramidus and Au. afarensis suggest a relatively rapid shift from Ardipithecus to Australopithecus in this region of Africa, involving either replacement or accelerated phyletic evolution.”

* Independent evolution of bitter-taste sensitivity in humans and chimpanzees. Wooding, S., Bufe, B., Grassi, C., Howard, M. T., Stone, A. C., Vazquez, M., Dunn, D. M., Meyerhof, W., Weiss, R. B., & Bamshad, M. J. (Dept of Human Genetics, Univ. of Utah, 15 N. 2030 East, Salt Lake City, UT 84112-5330 [e-mail: [email protected]]). Nature, 2006, 440, 930-934.
. . . “It was reported over 65 years ago that chimpanzees, like humans, vary in taste sensitivity to the bitter compound phenylthiocarbamide (PTC). This was suggested to be the result of a shared balanced polymorphism, defining the first, and now classic, example of the effects of balancing selection in great apes. In humans, variable PTC sensitivity is largely controlled by the segregation of two common alleles at the TAS2R38 locus, which encode receptor variants with different ligand affinities. Here we show that PTC taste sensitivity in chimpanzees is also controlled by two common alleles of TAS2R38; however, neither of these alleles is shared with humans. Instead, a mutation of the initiation codon results in the use of an alternative downstream start codon and production of a truncated receptor variant that fails to respond to PTC in vitro. Association testing of PTC sensitivity in a cohort of captive chimpanzees confirmed that chimpanzee TAS2R38 genotype accurately predicts taster status in vivo. Therefore, although Fisher et al.’s observations were accurate, their explanation was wrong. Humans and chimpanzees share variable taste sensitivity to bitter compounds mediated by PTC receptor variants, but the molecular basis of this variation has arisen twice, independently, in the two species.”

* A new genus of African monkey, Rungwecebus: Morphology, ecology, and molecular phylogenetics. Davenport, T. R. B., Stanley, W. T., Sargis, E. J., De Luca, D. W., Mpunga, N. E., Machaga, S. J., & Olson, L. E. (Wildlife Conservation Society, Southern Highlands Conservation Programme, P.O. Box 1475, Mbeya, Tanzania [e-mail: [email protected]]). Science, 2006, 312, 1378-1381.
. . . “A new species of African monkey, Lophocebus kipunji, was described in 2005 from two sites in Tanzania. We have since obtained a specimen killed by a farmer on Mt. Rungwe, the type locality. Detailed molecular phylogenetic analyses of this specimen demonstrate that the genus Lophocebus is diphyletic. We provide a description of a new genus of African monkey, and of the only preserved specimen of this primate. Information on the animal’s ecology and conservation is also presented.”

* Comment on “The brain of LB1, Homo floresiensis”. Martin, R. D., MacLarnon, A. M., Phillips, J. L., Dussubieux, L., Williams, P. R., & Dobyns, W. B. (The Field Museum, Chicago, IL 60605–2496 [e-mail: [email protected]]). Science, 2006, 312, 997-998.
. . . Endocast analysis of the brain Homo floresiensis by Falk et al. (Reports, 8 April 2005, p. 242) implies that the hominid is an insular dwarf derived from H. erectus, but its tiny cranial capacity cannot result from normal dwarfing. Consideration of more appropriate microcephalic syndromes and specimens supports the hypothesis of modern human microcephaly.

* Response to Comment on “The brain of LB1, Homo floresiensis”. Falk, D., Hildebolt, C., Smith, K., Morwood, M. J., Sutikna, T., Jatmiko, Saptomo, E. W., Brunsden, B., & Prior, F. (Department of Anthropology, Florida State University, Tallahassee, FL 32306 [e-mail: [email protected]]). Science, 2006, 312, 999.
. . . Martin et al. claim that they have two endocasts from microcephalics that appear similar to that of LB1, Homo floresiensis. However, the line drawings they present as evidence lack details about the transverse sinuses, cerebellum, and cerebral poles. Comparative measurements, actual photographs, and sketches that identify key features are needed to draw meaningful conclusions about Martin et al.’s assertions.

* Early stone technology on Flores and its implications for Homo floresiensis. Brumm, A., Aziz, F., van den Bergh, G. D., Morwood, M. J., Moore, M. W., Kurniawan, I., Hobbs, D. R., & Fullagar, R. (Dept of Archaeology & Natural History, Australian National University, Canberra, Australian Capital Territory 0200, Australia [e-mail: [email protected]]). Nature, 2006, 441, 624-628.
. . . “In the Soa Basin of central Flores, eastern Indonesia, stratified archaeological sites, including Mata Menge, Boa Lesa and Kobatuwa, contain stone artefacts associated with the fossilized remains of Stegodon florensis, Komodo dragon, rat and various other taxa. These sites have been dated to 840–700 kyr bp (thousand years before present). The authenticity of the Soa Basin artefacts and their provenance have been demonstrated by previous work, but to quell lingering doubts, here we describe the context, attributes and production modes of 507 artefacts excavated at Mata Menge. We also note specific similarities, and apparent technological continuity, between the Mata Menge stone artefacts and those excavated from Late Pleistocene levels at Liang Bua cave, 50 km to the west. The latter artefacts, dated to between 95–74 and 12 kyr ago, are associated with the remains of a dwarfed descendent of S. florensis, Komodo dragon, rat and a small-bodied hominin species, Homo floresiensis, which had a brain size of about 400 cubic centimetres. The Mata Menge evidence negates claims that stone artefacts associated with H. floresiensis are so complex that they must have been made by modern humans (Homo sapiens).”

Instruments and Techniques

* A universal microsatellite multiplex kit for genetic analysis of great apes. Roeder, A. D., Jeffery, K., & Bruford, M. W. (Biodiversity & Ecological Processes Group, Cardiff School of Bioscience, Main Bldg, Cardiff Univ., Cardiff, Wales CF10 3TL, U.K. [e-mail: [email protected]]). Folia Primatologica, 2006, 77, 240-245.
. . . “DNA profiling with microsatellite markers is a com-monly used genetic method of studying the great apes. An efficient method of generating the genetic data is amplification of multiple microsatellites in a single PCR reaction. Here we describe a PCR multiplex in which 9 genetic markers can be amplified simultaneously, thereby saving time, expenses and DNA. This marker system can discriminate between all the great ape species except bonobos and chimpanzees. Furthermore, the cumulative probability of identity values were low for all four species tested.”

* A dynamic force analysis system for climbing of large primates. Schoonaert, K., D’Août, K., & Aerts, P. (Lab. of Functional Morphology, Dept of Biology, Univ. of Antwerp, Universiteitsplein 1, BE-2610 Wilrijk, Belgium [e-mail: [email protected]]). Folia Primatologica, 2006, 77, 246-254.
. . . “Registering substrate reaction forces from primates during climbing requires the design and construction of customized recording devices. The technical difficulties in constructing a reliable apparatus hinder research on the kinetics of primate locomotion. This is unfortunate since arboreal locomotion, especially vertical climbing, is an important component of the hominoid locomotor repertoire. In this technical paper, we describe a custom-built climbing pole that allows recordings of dynamic 3-dimensional forces during locomotion on horizontal and sloping substrates and during vertical climbing. The pole contains an instrumented section that can readily be modified and enables us to register forces of a single limb or multiple limbs in a broad range of primates. For verification, we constructed a similar set-up (which would not be usable for primates) using a conventional force plate. Data for a human subject walking on both set-ups were compared. The experimental set-up records accurate and reliable substrate reaction forces in three orthogonal directions. Because of its adjustability, this type of modular set-up can be used for a great variety of primate studies. When combining such kinetic measurements together with kinematic information, data of great biomechanical value can be generated. These data will hopefully allow biological anthropologists to answer current questions about primate behaviors on vertical substrates.”


* Father-daughter inbreeding avoidance in a wild primate population. Muniz, L., Perry, S., Manson, J. H., Gilkenson, H., Gros-Louis, J., & Vigilant, L. (S. P., Dept of Anthropology, UCLA, Los Angeles, CA 90095 [e-mail: [email protected]]). Current Biology, 2006, 16, R156-R157.
. . . “The most common way by which social animals avoid breeding with relatives is for members of one or both sexes to disperse before reproducing. In capuchin monkeys – as in most primates – males disperse while females benefit from lifelong relationships with maternal kin within the group. If alpha males – who sire most offspring in a given group – retain their rank for longer than 6 years, the age at which females reach sexual maturity, father-daughter inbreeding could occur. Here, we combine data from long-term observations and DNA analyses and present extensive genetic evidence for effective avoidance of father-daughter inbreeding without dispersal in wild capuchin monkeys.”
