Environment- and Season-Influenced Alopecia in Juvenile Rhesus Macaques

Introduction

Both the seasons and stress can play an important role in the hair condition of macaques kept in outside open enclosures. Hypergrooming and self-mutilation due to boredom without enough enrichment may cause alopecia, apart from other factors such as the presence of ectoparasites, bacterial and fungal infections, hormone imbalance, nutritional deficiencies, excess use of detergents, and psychogenic causes. Seasonal alopecia in affenpinschers and other dogs has been reported (Waldman, 1995). Hair loss in subordinant animals due to stress has been reported in nonhuman primates (Burge et al., 1997). Also photoperiod and hormonal activity (pregnancy and lactation for females, breeding for males) have influenced hair loss and growth patterns in rhesus macaques (O’Neill-Wagner, 2002). In this paper we show how changes in environment prevented seasonal alopecia in juvenile rhesus macaques.

Original Conditions

Housing and indoor environment: Our juvenile (ages 10-15 months) rhesus macaques (Macaca mulatta) were kept in peer groups of about 15 individuals in an outdoor run for most of the year. During the middle of winter and summer they were kept indoors, where they were maintained under standard environmental conditions in accordance with the guidelines for care and use of animals in scientific research (Indian National Science Academy, New Delhi), in a CPCSEA (Committee for the Purpose of Control and Supervision of Experiments on Animals)- registered animal facility with air-conditioned rooms: temperature 22-25° C, humidity 55-60%, 12:12 photoperiod, and individual stainless steel cages. The animals were fed with commercial pelleted primate feed and soaked gram (Cicer arietinum, chick peas) in the morning, bread in the afternoon, and fruits and vegetables in the evening. They had water ad libitum.

Outdoor open enclosures: After winter, during March, the animals were transferred to semi-natural outdoor enclosures, 30 x 25 x 10 ft. The enclosures included enclosed rooms (30 x 5 x 5 ft.) for resting, and enrichment devices such as perches, swings, and small rocks. Water was provided ad libitum through stainless steel nipples, which are fixed at 2-ft intervals in the water pipe.

During the months of April to June 40% of the juveniles transferred from indoor rooms to outdoor enclosures had hair loss in varying degree. Skin scrapings from all those animals were subjected to parasitogical and fungal examination. In addition hematological and biochemical parameters of those animals were examined to rule out other possible causes of alopecia. The animals were also given a multivitamin suspension daily, because we suspected hair losses might be due to vitamin deficiencies. We transferred some animals with alopecia back to indoor rooms, suspecting that hair losses might be due to high temperatures (39-44° C) in the open enclosures.

Figure 1: Hair loss spreading from back of neck to whole back in a juvenile rhesus monkey kept in an open enclosure.

First Results

Parasitological and fungal examinations of skin scrapings revealed no arthropods or fungal growths, and cultures showed no growth of organisms. Hematological and biochemical parameters revealed no significant changes, and there was no initiation of hair growth in the animals supplemented with multivitamins.

The juveniles who were transferred to individual indoor rooms recovered from alopecia and hair growth began within a week. Hence we concluded that hair losses in outside enclosures are due to environmental stress; to ease that stress the outdoor enclosure was modified.

Modifications to the Enclosure

Figure 2: Modified open enclosure.

Figure 2 shows an outside enclosure modified with more trees, additional covering, and sprinklers, all of which reduced the temperature to 33-40° C. In addition, we put electric coolers in the enclosed rooms. The water provided was also cooled. We also gave vitamin C-rich juicy fruits and continued to give supplemental vitamins. Further loss of hair was controlled and there was also progress in hair growth.

Figure 3: Openings to rooms in lower part of the enclosure.

Conclusions

Group housing is probably the most appropriate housing for macaques (Bernstein, 1991), but the problems encountered in group housing include bites and scratches, symptoms of dietary deficiency, difficulty in eliminating prevalent infectious agents, and hair loss in varying degrees (Burge et al., 1997); hence it is important to eliminate such problems when animals are kept in the open enclosures. As CPCSEA requires housing laboratory macaques in outdoor enclosures for their psychological well-being, care must be taken to provide an appropriate environment and to reduce stress for those animals. When macaques are kept in outdoor enclosures in climates similar to India’s during the months of April to June they are more prone to stress due to high temperatures. Changes such as planting trees around the open enclosures, adding coolers and sprinklers, and providing cold water ad libitum can reduce this stress, and seems to prevent hair loss during this season. In addition to normal feeding, diet should be supplemented with vitamin C-rich fruits.

To conclude, if macaques are to be kept in outdoor group housing during hot months, a proper environment should be provided to reduce heat stress, which, in turn, prevents hair loss.

Stereotypical Behavior: A LAREF Discussion

The discussion was initiated by the observation that animals kept in legally minimum-sized, unstructured enclosures very often exhibit stereotypical behaviors. Traditionally these repetitive movement patterns without obvious goals or functions are categorized as “abnormal”.

Figure 1: Stereotypical ear-pulling in an individually caged rhesus macaque.

It was argued that a healthy animal kept in a small, barren enclosure has little choice of expressing his/her biologically inherent drive to engage in species-typical behaviors other than pacing back and forth, running in circles, somersaulting, rocking, self-biting, bar-biting, ear-pulling (Figure 1), hair-pulling, eye-poking, etc. There is nothing really “abnormal” except the abnormally restrictive and abnormally boring housing condition that induces the stereotyped expression of these activities. The majority of macaques kept in conventional standard cages exhibit stereotypical activities (Erwin & Deni, 1979; Lutz et al., 2003). These behavioral patterns thus become “normative” under the given circumstance (Reinhardt). In caged mice, barbering (fur and whisker trimming) is another example of a stereotypy that has become a normative behavior pattern within the context of inadequate living conditions (Anonymous).

It is the artificial environment in which stereotypies develop that is “abnormal” as it does not allow the animals to satisfy basic behavioral needs (Olsson). The label “abnormal” would be more fitting for the inadequate confinement condition rather than for the subject’s unsuccessful attempt to adjust to it. We tend to project abnormality onto animals rather than onto the people who create deficient living quarters for them. It would be fair to first focus on the husbandry conditions, study the environmental factors that lead to the development of abnormal behaviors, and then correct these factors in order to prevent abnormal behaviors in the future (Reinhardt). These unsuccessful attempts of adjusting could also be described as “behavior indicative of an abnormal environment” (Patterson-Kane).

Many stereotypies are signs of frustration, with the subject being chronically thwarted from expressing basic activities such as taking a few free steps in one direction, climbing and perching, retreating to a secluded place, foraging, and interacting with another conspecific (Reinhardt). Scientific evidence suggests that animals who engage in stereotypical behavior show a disorganization of brain function (Kraemer et al., 1997; Garner & Mason, 2002) and alterations in their stress reactivity (Tiefenbacher et al., 2004). These “abnormalities” are likely to introduce uncontrolled variables into research data, thereby jeopardizing the validity of science that is done with the affected subjects. It is ironic that the unstimulating, minimum-sized housing environment that promotes the development of stereotypies is often defended with the assertion that it minimizes the number of extraneous variables that could influence research data (Reinhardt).

A temporary replacement of stereotypical behaviors with species-typical behaviors does occur with environmental enrichment, but the effect is usually only of short duration, because the subject quickly loses interest in the enrichment and is then left again with nothing to do but engage in the habitual, repetitive behavior pattern(s) (Reinhardt).

The question was raised whether any of the 140 LAREF members can share success stories of environmental modifications that cured animals from stereotypical behaviors:

1. Feather-pecking was virtually eliminated in group-housed turkeys by providing the animals with straw, UV light and vertical visual blinds (Sherwin).
2. Hair loss, presumably resulting from hair pulling and hair eating, was successfully treated by transferring an individually caged rhesus macaque to a compatible group-housing arrangement (Down).
3. Seven individually caged rhesus macaques were cured of self-injurious biting by transferring them to compatible pair-housing arrangements (Reinhardt). Since very stressful situations can trigger self-injurious biting even in group-housed animals, transfer to pair-housing probably suppressed rather than eliminated this stereotypy (Davis).

Preventing stereotypies by rearing and housing the animals in species-appropriately enriched conditions is probably a better strategy than waiting for the development of these behavioral problems and then investing time and resources in the futile attempt to eradicate them (Garner).

Callitrichid Triplets: A Discussion

Jan Vermeer <j.vermeer@la-vallee-des-singes.fr>, of La Vallée des Singes, Romagne, France, wrote on May 16: “We had several cases where two or all three babies died when we left triplets with their mother. We therefore remove one of the babies on the first day to give the two others better chances for survival. (If you wait longer, it might be too late.) I know that many zoos had tamarins or marmosets that reared all three, and it would be interesting to know what the survival chances for triplets really are.” Three other similar responses were posted.

Vanessa Phelan <grillasruleis@rogers.com>, gorilla keeper at the Toronto Zoo, wrote: “We had triplets born to our white-eared common marmosets on several occasions when I worked with them many years back. For some reason, although the male was carrying them well and they were going back to mom to nurse, only two survived each time. We did manage to retrieve one triplet and nursery raised him. He was eventually successfully reintroduced back to other family members.”

And another response: “I’ve worked with both marmosets and tamarins who have given birth to triplets in captivity. After many cases of ‘giving mom a chance’ we have learned to try and allow the infants to nurse from mother’s milk for one day and then automatically pull one. If you wait too long you are most likely going to end up with at least one infant in a weakened condition. That infant could either not survive at all, or be in such a compromised state that the already intense work of hand-rearing becomes even more difficult.

“No matter how good the parents are it never seems that all three triplets are able to get an even and adequate share if left to nurse from their mother. If you can raise the infant on formula until it is mobile, then train it to run to a bottle or eye dropper, it can be reintroduced to the family group while it is still not yet weaned and continue being fed by its keeper. This is socially the best chance the young marmoset will have for a ‘normal’ future life.”

Kirsten Christensen <KChristensen@cabq.gov>, Mammal Dept. Supervisor of the Rio Grande Zoo, wrote on May 17: “Just to offer a counterpoint, we had triplets born to our cotton-top female in 2001. We were already preparing for observations because during the pregnancy the father died. The female was housed with her two previous litters of twins (male and female). We monitored them closely, and all three nursed. Initially, mom Zinger carried all three, but eventually the siblings kicked in and helped with rearing the triplets. All three have survived to adulthood. The only caution I would add was that Zinger was a highly experienced, exceptional mother, and that during the early weeks, the triplets did get into battles with each other for position. I hadn’t realized what a great job Zinger and the siblings did until your question arrived! Good luck to you.”

Dominic Wormell <eldom@jerseymail.co.uk>, of the Jersey Zoo, wrote: “We recently had the case of a female pied tamarin who was very reluctant to carry her twins during the day. Consequently the twins became very weak on the first and second days after birth, and we nearly pulled them. We decided to shorten the daytime hours for the group considerably, i.e., lights on at 0800, twilight at 1300 and lights off at 1700. The group was shut in for this. This appears to have worked and the infants are doing well. The reasons for the success are: first, the group are far less active shut in with the shorter day length and thus the infants don’t have to expend valuable energy clinging on for dear life as the carrier leaps around; and second, the greater amount of time the mother spends in the nest box, due to the longer hours of darkness, the greater opportunity the infants have to suckle, suckling after the dam has retired to the nest box being the norm.

“I think if triplets were to be left with the mother, this regimen would probably give all three infants the best chance of being mother-reared. I would only suggest this regimen for the first couple of weeks.”

Alex wrote again: “Thanks for all the great responses. I was glad to see so much of the information correlate. Our pair of Kuhli’s are first-time parents. One of the babies dropped off and we immediately picked it up and began the hand-raising protocol. The infant seemed to perk up after getting warmed and having a feeding, but it was not thriving. The little guy lasted until 4 pm today. He just never really came all the way back. We hope the other two will be okay. At least we know we are ready, thanks to all the dedicated animal personnel out there!”

Later that day, Alex added: “It looks like we are not done yet! We are now hand-rearing a second infant. This one is doing better, so we are hopeful. I have a request...could those of you whom actually did this before send me your formula and the amounts fed? We are curious to see if there is much difference among the different zoos. We are currently using two protocols.”

Patiño, E. M., & Borda, J. T. (1997). The composition of primates’ milk and its importance in selecting formulas for hand-rearing. Laboratory Primate Newsletter, 36[2], 8-10.

As we were preparing this for publication, we received a final note from Alex: “This is still a sad subject for me as we lost all three babies. I may have killed the last one by feeding it too much and it aspirated. A sad way to learn.”

Do Chimpanzees Like Music? Will They Choose Their Own?

What a blast and great fun animal research can be... especially if you do not have the money to build computer equipment...and then must improvise! Who knows how it may end?

We conducted a “music study” with the chimpanzees at the Primate Foundation of Arizona (Howell, et al, 2003). The next step was to design a computerized system that would allow them to choose their own music.

We contacted computer gurus, we contacted Arizona State University students, we contacted until we were almost dead! There were no results, because we had no money and students don’t have the time!

So…we went back to the drawing board. After two full weekends on the Internet and scouring toy stores, we found a small 10’’ x 12” toy plastic piano (Little Tykes) with four keys, tiny xylophone-type key strikes, no batteries, no extra music. We attached a handle. We presented it to individual chimpanzees.

The idea was…should they strike a key, Pavarotti (or whatever music was assigned to that key) would instantly come on, using an observer-operated laptop. Because the keys were colored (red, green, blue, yellow), we knew we would also be battling a color preference. The “plan” was that once a pattern was set, we would change the music-color connection. Would they always hit RED (by color choice), or would they search until they found YELLOW and Pavarotti?

Well...it seems like the chimpanzees like to compose their own music! Some with “snatch and grab”...“Mine, Mine, Gimme! Gimme!!” But others are very content to make their own tunes, one key at a time, and several seem to prefer “Jerry Lee Lewis chording”! They totally ignore what music they have “called for”, i.e., Pavarotti, Patsy Cline, Indian Flutes, etc., and stay intent upon the music they are making themselves…on a tiny plastic piano with four keys!

Oh, finally - one or two chimpanzees seem to have the same idea as we. Hit the key, listen, hit another key, listen. Perhaps we will get there…maybe!

The important thing is...chimpanzees like music! Stay tuned!

Rhesus cDNA Sequences and Microarrays

The National Center for Research Resources (NCRR) recently funded two projects to derive rhesus macaque complementary DNA (cDNA) sequences and design rhesus-specific microarrays. In the first project, Michael Katze (Washington National Primate Research Center) and Shawn Iadonato (Illumigen Biosciences, Inc.) are preparing rhesus cDNA libraries and sequencing the resulting clones. A general description of the project plus microarray data that can be downloaded are available at <primate.viromics.Washington.edu>. The cDNA sequences in FASTA format are also available.

In the second project, Robert Norgren (University of Nebraska Medical Center) and Eliot Spindel (Oregon NPRC) are designing rhesus-specific microarrays in Affymetrix format, with input from the research community. For a current list of sequences expected to be on the chips, plus information for providing input, see <rhesusgenechip.unomaha.edu>. Sequences determined by both projects also will be deposited in GenBank, which can be accessed through the National Center for Biotechnology Information. - From the NCRR Reporter, Spring, 2004

News Briefs

Remember Clyde, the parenting male orangutan (LPN, 37[1], 18-19), described in 1998 by Betty Jo McDuffee? The San Diego Zoo said Thursday that it knows the father of Cinta, a 3-month-old orangutan. Zookeepers had been wondering since spotting Cinta’s mother, Indah, mating with 9-year-old Satu as well as with Satu’s 27-year-old father, Clyde.

Some suspected Clyde was the father because of his riper age. But hair and blood samples pointed to Satu, even though he lacked a beard, long dreadlocks, and large cheeks - traits that female orangutans find attractive, the zoo said.

“Despite appearances, it turns out Satu is indeed man enough to be a daddy, and Clyde is now a grandfather,’’ the zoo said in a press release. The San Diego Zoo is now home to three generations of orangutans. It is the first offspring for Indah, the 17-year-old mother. - June 17, Associated Press report

Chimfunshi Opens 150-Acre Enclosure

The Chimfunshi Wildlife Orphanage, which has cared for injured and unwanted chimpanzees since 1983, marked another milestone in its development recently when it released 12 chimpanzees into a 150-acre enclosure at the sanctuary in central Zambia. The group was transferred June 12 to a fenced area that includes thick forests, fruit groves and open grassland. The move is considered permanent, but the chimpanzees will still be fed regularly and their health will be monitored by Chimfunshi staff. The facility includes night cages and a food storage building.

This move was overseen by a veterinary team that included Dr. Peter Buss of South Africa. Dr. Sally Shiel of Zambia, Dr. Tink Robey of South Africa, and Chimfunshi’s resident veterinarian, Dr. Eric Dubuis. The chimpanzees had been living in a 14-acre enclosure. They were anesthetized and then loaded onto a truck and transported the 12 kilometers to their new home.

Dutch Zoo Chimpanzees Get Second Chance

Two adult male chimpanzees that grew up as virtual brothers and formed deep emotional bonds at Artis Zoo in Amsterdam will remain together permanently after being transferred this week to the Great Ape Project (GAP)-Brazil sanctuary <www.greatapeproject.org>. Rakker and Simon, both 11 years of age, were born in captivity. Rakker was acquired from the Antwerp Zoo in Belgium at 18 months of age as a playmate for Simon, born at the Artis Zoo, but rejected by his mother.

The chimpanzees were raised together for three years before being placed in the main social group of adults at the Artis Zoo. But Simon’s mother, who is the alpha female of the group, refused to accept Rakker and attacked him severely, nearly killing him on one occasion. Attempts to keep Rakker from the main group for his own safety left Simon lonely and disconsolate.

The Artis Zoo, which was suffering from overcrowding in its chimpanzee enclosure, looked at options elsewhere in Europe and Asia before contacting GAP-Brazil, which already cares for 26 chimpanzees. Rakker and Simon arrived on June 9 accompanied by keepers from the Artis Zoo, who will help ease the chimpanzees’ transition into their new surroundings.

The GAP-Brazil sanctuary is situated on the outskirts of São Paulo and was created to care for injured and unwanted chimpanzees and other primates. Most of the sanctuary’s residents have come from South American circuses or zoos.

Gorilla Escaped Enclosure by Leaping Trench, Wall

A gorilla that was shot to death by police after breaking out of its enclosure at the Dallas Zoo in March escaped by leaping over a 12-foot-wide trench and a wall that separates animals from visitors, officials said Tuesday. Jabari, a 340-pound western lowland gorilla, went on a 40-minute rampage March 18, snatching up a toddler with his teeth and injuring three other people.

The gorilla enclosure is constructed so that animals are roughly at visitors’ eye level, but they are separated from visitors by a 14-foot wall and the trench. Zoo investigators believe the gorilla probably got a running start and sailed over the trench and the wall, clearing an electrical wire atop the wall that is supposed to give a mild shock.

The zoo investigation found no human errors that might have led to the gorilla’s escape, such as doors left open. The zoo is raising the walls to 15 feet. - Associated Press, June 15

Gorillas Escape from Enclosure at Ohio Zoo

Seven gorillas escaped from their enclosure at the Columbus Zoo and spent a few hours wandering free in the ape house. The zoo had closed for the day Saturday, July 3, when keepers noticed a gorilla loose in the house outside of the gorilla enclosure. A door had been accidentally left open, allowing the animals to roam areas usually off limits to them. The gorillas weren’t able to leave the ape house building, but zoo officials say the group managed to have a wild time scattering supplies.

Nearly 4,000 acres of prime mountain gorilla habitat have been cleared by illegal settlers in Africa’s Virunga National Park, a World Heritage Site. The settlements were uncovered by the Congolese Institute for the Conservation of Nature, which found that, since April, thousands of people from Rwanda and the Democratic Republic of Congo (DRC) have destroyed large tracts of the park to create agricultural and pastoral land.

Located in DRC on the border with Rwanda and Uganda, Virunga National Park is home to more than half the world’s 700 remaining mountain gorillas. The park is also home to the world’s only golden monkey population. The mountain gorillas generate around $2 million for the region annually from tourism.

According to information received by the World Wildlife Fund (WWF), the Wildlife Conservation Society, and their conservation partners, most of the destruction took place from early May to June. Several thousand people moved in to the area to farm illegally in Virunga, with support from influential local individuals who sold plots of land within the national park. The forest was clearcut and turned into timber or charcoal before crops were planted.

WWF is urging the Congolese and Rwandan governments to take measures to enforce the UN World Heritage Convention that protects this unique site. WWF is also calling on the international community to fund park patrols, the peaceful evacuation of illegal settlers, and the restoration of destroyed areas. - from a WWF press release, July 5

Great Ape Trust Nearing Completion

The first primates will soon move into Iowa’s first primate research facility in Des Moines. Construction on the building is right on schedule, and officials say they’re on track for completion. The building will be one of the premiere learning facilities for primate research in the country, but it won’t be open to the public. About two hundred neighbors toured the facility at a private event Tuesday evening.

Next month, two orangutans, Azy and Indah, from the National Zoo in Washington, DC, will be the first apes to arrive at the Great Ape Trust of Iowa. - WorldNow, July 14

LSU-Tulane Center for Infectious Disease Research

The Louisiana State University (LSU) School of Veterinary Medicine has received a $9.9 million grant to establish a Center of Biomedical Research Excellence (COBRE). This Center grant from the National Center for Research Resources provides substantial funds into developing faculty for independent funding by the National Institutes of Health (NIH) traditional mechanisms. The grant will last for five years and can be competitively renewed for five or more years. The School’s grant will allow it to create a Center for Experimental Infectious Disease Research. “This Center constitutes a strategic alliance between the School of Veterinary Medicine, the LSU College of Basic Sciences, and the Tulane National Primate Research Center,” said Dr. Konstantin G. Kousoulas, the administrator of the COBRE program at the LSU School of Veterinary Medicine. Currently, a total of five assistant professors have research projects in the grant, representing the Department of Pathobiological Sciences, School of Veterinary Medicine; the Department of Biological Sciences, College of Basic Sciences; and the Department of Microbiology and Immunology, Tulane National Primate Center (TNPRC). A number of other faculty and staff will participate in research cores in the School and TNPRC.

Participants in the COBRE program will have access to specialized Core Facilities at both TNPRC and the Division of Biotechnology and Molecular Medicine. The COBRE grant provides funding and research capabilities that will give assistant and associate professors the opportunity to establish research programs that will effectively compete for independent funding by NIH. Once a faculty member receives his or her own NIH funding for a particular research program, he or she will be rotated out of COBRE and replaced by other eligible faculty.

Gorilla with Inoperable Cancer Euthanized

A 39-year-old gorilla with inoperable cancer was euthanized at the Columbus Zoo and Aquarium, zoo officials said Tuesday. Exploratory surgery last week confirmed the cancer in Sylvia, a western lowland gorilla. She was put to death Monday.

Sylvia was born in the wild and caught when three months old. She spent time at the National Zoo in Washington and the Baltimore Zoo before coming to Columbus. Sylvia never conceived a child, but was a surrogate and adoptive mother to juvenile gorillas at the Columbus Zoo, which in 1956 was the first zoo to have a western lowland gorilla born in captivity. - Associated Press, August 4

Monkeys Escape Cages at Research Center

A group of monkeys escaped from their cages at the New Iberia Research Center Monday. Only one of the monkeys escaped the Center’s grounds. It was recovered at a nearby business. By Monday evening all of the escaped monkeys were back in their cages.

The Center is a primate facility run by the University of Louisiana at Lafayette. It breeds nonhuman primates and provides pre-clinical safety trials and evaluations of pharmaceuticals and biotechnology products. The rhesus monkeys, used for breeding, did not pose a risk to the public, a university spokesman said. The incident is under investigation. Officials believe the escape was the result of human error. - Associated Press, August 9

KWS to Kill More Than 200 Monkeys

Over 200 monkeys that have invaded farms in the famine-hit Ndeiya location of Limuru will be killed at the weekend, the Kenya Wildlife Service (KWS) has said. The primates have become a menace, causing great crop damage and meting out violence on the residents and KWS officials who have tried to remove them from the farms. Limuru District Officer (DO) Isaac Masinde and local KWS officials said they would eliminate the monkeys.

Masinde said their attempts to push the primates back to the forest had failed, leaving them with no alternative but to kill them. The KWS officials are expected to shoot the animals dead. The DO said the monkeys had created fear among the residents of Ndiuni and Githunguchu villages, imposing a curfew on them such that they could not venture out of their compounds from 5 p.m. to 8 a.m.

Masinde said so far 10 monkeys had been shot dead, which seems to have provoked the others to violence. Yesterday, the residents and KWS officials who went to scare the monkeys away got a shock when three well-armed battalions of monkeys stoned them. Though the officials of the wildlife organization were armed with sophisticated weapons, they had to scamper for safety in neighboring homes.

And lately, the monkeys have grown bolder, conducting daylight raids on homesteads and taking away any edible material they find. Masinde said they were waiting for reinforcements from the Ngong KWS headquarters. - The East African Standard (Nairobi), August 6

Additions to PASA Advisory Board

The Pan African Sanctuaries Alliance (PASA) has announced two additions to the PASA Advisory Board. Barbara Cartwright, a campaigner for the International Fund for Animal Welfare (IFAW) - Canada, and Dr. Tony Mudakikwa, the senior veterinary officer of the Office of Rwandan Tourism and National Parks (ORPTN), were elected to the PASA Advisory Board at the recent PASA 2004 Management Workshop in Johannesburg, South Africa.

Visitors Watch Bonobo Birth at San Diego Zoo

A bonobo was born at the San Diego Zoo on August 15, 2004, to the surprise of many zoo visitors who witnessed the birth. The bonobo (or pygmy chimpanzee) is a critically endangered species and rarely seen in zoos. The San Diego Zoo has a successful breeding program, and this birth marks the third offspring for the mother Lana. - Yahoo News Spanish Town Refuses Permit for Retired Chimps

Dozens of chimpanzees from a Dutch laboratory face a housing crisis after plans for their retirement on the Spanish coast collapsed because of residents’ fears they would carry infectious diseases. This illustrates the dilemma of what to do with research chimps as more countries decide it is no longer acceptable to use humankind’s closest genetic relative for experiments.

The Dutch government agreed to pay for 39 healthy chimps to move to a proposed state-of-the-art facility near the town of Relleu, Spain. The center, to be built on 100 acres of land, was to feature trees, play structures, and housing with shady areas underneath. But Relleu has refused to grant a permit, fearing the chimps carry diseases. Pleas from the Spanish regional government, and a visit from expert Jane Goodall, failed to sway town officials.

‘‘We are in trouble, that’s for sure,’’ said David van Gennep, director of Stichting AAP, the Dutch primate shelter behind the move. The 39 chimps ‘‘could end up spread around the world. But we’re not willing to accept having them put them down,’’ he said. Caring for chimps is costly, and high-quality zoos are reluctant to accept laboratory chimps because they may have developed psychological problems.

Meanwhile, countries like The Netherlands have banned tests on chimps. The U.S. Congress voted in 2000 to allow primate testing to continue, but with restrictions. - Associated Press, August 20

Rare Twins Born to Mountain Gorillas

On May 17, second-time mother Nyabitondore, 12 years old, gave birth to twins, only the third ever recorded, in Volcanoes National Park, Rwanda. Since the middle of last year, gorilla troops have produced 14 other babies, and the birth of the twins has delighted conservation experts.

In 1986, the first recorded pair of twins died after just nine days. Of the second pair, born in 1991, one infant died within a month. The other survived to adulthood, only to be killed by poachers attempting to steal a baby gorilla in 2002. Gorilla troops are ferociously protective of their young and poachers often have to kill mothers and other adults to steal babies.

Volcanoes National Park, Africa’s first, was established by Rwanda’s Belgian colonial rulers in 1925 after Carl Akeley of the American Museum of Natural History made a plea to protect the gorillas. It lies on the Rwandan side of a mountain range that straddles the borders of Rwanda, Congo and Uganda. Adjacent parks in Congo and Uganda are both known as Virunga National Park. The three parks are home to the world’s entire mountain gorilla population. A census conducted late last year found that the number was up 17 percent since the last count 15 years ago. - from Associated Press and African Wildlife Foundation Web reports

• University of Texas M. D. Anderson Cancer Center
• Primate Foundation of Arizona
• Alamogordo Primate Facility
• The University of Louisiana at Lafayette New Iberia Research Center

Discussions during the meeting included updating current chimpanzee resources available to the biomedical and behavioral community, demographics, and the scientific needs for chimpanzees as animal models for human disease research. The Institute for Laboratory Animal Research (ILAR) document on recommendations regarding the management of chimpanzees was reviewed, and the Food and Drug Administration representatives detailed the FDA’s perspective on the use of chimpanzees as animal models. Professionals from each field detailed the importance of the animal model for neuroscience research, genetics and genomics, and comparative anthropology, as well as some critical infectious disease and safety study requirements.

At the end of the meeting Dr. Chris Abee summarized the presentations and performed a SWOT analysis (strengths, weaknesses, opportunities, and threats). Action items identified included (but were not limited to) the following:

• Periodically evaluate stakeholder priorities.
• Foster awareness of appropriate use in scientific/regulatory and public/political communities.
• Develop a coordinated approach to addressing problems with accessing chimpanzees as animal models for research and chimpanzee resources.
• Nurture relations with the U.S. Congress and with the European Community.
• Update the Institute for Laboratory Animal Research (ILAR) publication titled “Chimpanzees in Research, Strategies for Their Ethical Care, Management, and Use” to reflect global utilization and strategic needs.

Lastly the participants identified the need to create a leadership group to assure the future availability of chimpanzee resources for basic and applied research. The “Chimpanzee Resource Executive Committee” is currently being formed. It will address these and other needs associated with a global resource currently being overseen by a small handful of institutions partially supported by the National Center for Research Resources - NIH.

Award Nominations

The Animal Welfare Institute (AWI) and the Johns Hopkins Center for Alternatives to Animal Testing (CAAT) have issued a call for proposals for Animal Welfare Enhancement Awards. An anonymous donor has provided funds to award up to twelve applicants with funds for proposals intended to improve the welfare of laboratory animals. The focus of these awards is to refine the housing, handling and/or experimental situations for laboratory animals. This program excludes research studies with great apes.

Studies may, for example, examine:

• how physiological and behavioral stress responses to common husbandry (e.g., capture) and traditional treatment procedures (e.g., gavage, injection, blood collection) can be reduced or eliminated (e.g., by training the subjects to cooperate rather than resist);
• whether animals caged at different tier levels show different physiological and behavioral stress responses when being approached by personnel, and how these responses can be minimized or avoided;
• whether the presence of a compatible companion buffers physiological and behavioral stress responses to experimental situations (e.g., enforced restraint);
• whether animals kept in legally minimum-sized cages benefit from a moderate increase in space that is (a) empty versus (b) structured in species-appropriate ways (e.g., shelter, visual blind, perch, platform, PVC tube).

Any studies to be undertaken must be non-invasive, with the possible exception of obtaining blood for biochemical measurements. If possible, animals should be trained to cooperate during venipuncture. Objective measures might include behavior, coat appearance, body weight, or analysis of feces, urine, or blood as described above.

Each award will be for $6,000. In the case of successful completion of the application, some individuals may be invited to present their papers at a national symposium. Additional funds will be provided for travel to these meetings.

This award is limited to North American applications. The proposal itself should be in the form of a letter clearly stating the objectives of the study and the anticipated outcomes. It should provide sufficient detail so that reviewers can understand what is being proposed, how it will be achieved, and how the data will be evaluated.

These awards are intended for laboratory and animal technicians; senior investigators can sponsor them, however. Each proposal must be approved by the Animal Care and Use Committee, and the proposal itself must be co-signed by the Head of Animal Services at the institution. Applications should be sent to Ruth Brady [e-mail: rbrady@jhsph.edu]. Any parts of the application that cannot be sent by e-mail must be sent in multiples of 10 copies each to: Alan M. Goldberg, The Johns Hopkins Center for Alternatives to Animal Testing, 111 Market Place, Suite 840, Baltimore, MD 21202-6709.

The deadline for submission is November 1, 2004. Applications will be reviewed by an international group of reviewers. The AWI and CAAT then will make the final decisions on those proposals to be funded. Successful applicants will be funded by February 28, 2005.

Each successful applicant must send a final report of the completed study to Ruth Brady [e-mail: rbrady@jhsph.edu] and Viktor Reinhardt [e-mail: viktorawi@siskiyou.ne] by November 1, 2005. These reports will be posted on such Websites as Altweb <altweb.jhsph.edu>, the Animal Welfare Institute <www.awionline.org>, the Animal Welfare Information Center <www.nal.usda.gov/awic>, and other sites, as appropriate. It is hoped that successful applicants also will submit manuscripts of their projects and their outcomes to a professional journal.

This program announcement encourages the submission of applications for research to enhance animal stem cells as model biological systems. Innovative approaches to isolate, characterize, and identify totipotent and multipotent stem cells from nonhuman biomedical research animal models, as well as to generate reagents and techniques to characterize and separate those stem cells from other cell types, are encouraged.

Embryonic stem cells and other stem cells are valuable biomedical research models for the study of biological and disease processes, and for creation of disease models. In addition, these cells hold promise as model systems for development of therapeutics and for development of replacement tissues through understanding of the processes that control cellular differentiation.

Thus far, embryonic stem cells have been isolated from some biomedically important nonhuman research models. In addition, stem cells with a more restricted potential have been characterized from post-embryonic tissue types. However, research is needed to provide for a full array of totipotent and multipotent stem cells from nonhuman biomedical research animal models, as well as to provide the research tools to identify, characterize, and purify those cells.

This initiative will support the isolation and characterization of embryonic and other multipotent stem cells in a variety of nonhuman animal species. For detailed information, and where to send inquiries, see <grants.nih.gov/grants/guide/pa-files/PA-04-125.html>.

Fyssen Foundation Research Grants

The aim of the Fyssen Foundation is to “encourage all forms of scientific inquiry into cognitive mechanisms, including thought and reasoning, which underlie animal and human behavior; their biological and cultural bases; and phylogenetic and ontogenetic development”. The Foundation supports research in ethology, psychology, neurobiology, anthropology, ethnology, human paleontology, and archeology.

The Foundation will award research grants to support postdoctoral researchers, under 35 years of age in the biological sciences and under 40 years of age in the human sciences, who wish to work independently by establishing around them a research team to achieve a collective scientific operation in a laboratory in France, and who will work in keeping with the Foundation’s goals. Priority will be given to researchers who will develop their project in a laboratory other than those in which they received their doctorate and are presently working. The grant can range from 15,000 to 30,000 euros without renewal. Financing for equipment above 7500 euros is excluded. One year after the award, the researchers will have to provide a detailed financial report about the use of the grant and a short scientific report in French.

Applications should consist of:

• applicant’s CV and list of publications;
• description of the research project;
• description of the budget;
• names of people who have been approached about working on the project;
• list of other financial requests;
• a letter from the inviting laboratory, including the original copy; and
• recommendation letters from two senior scientists outside the inviting laboratory, including original copies.

Primate Conservation, Inc. - Call for Grant Proposals

Primate Conservation, Incorporated (PCI), is a not-for-profit foundation founded to fund field research that supports conservation programs for wild populations of primates. Priority will be given to projects that study, in their natural habitat, the least known and most endangered species. The involvement of citizens from the country in which the primates are found will be a plus. The intent is to provide support for original research that can be used to formulate and implement conservation plans for the species studied.

Primate Conservation, Inc., will grant seed monies or provide matching grants for graduate students, qualified conservationists, and primatologists to study rare and endangered primates and their conservation in their natural habitats. Grants have averaged approximately $2,500, with a maximum grant of $5,000. We do not support conferences, travel to scientific meetings, legal actions, tuitions or salaries at institutions, or overhead costs.

Proposals are evaluated on competitive basis. Applications are screened by outside reviewers and the Board of Directors of PCI. All appropriate projects will be considered, but the regions of current interest are Asia and West Africa. Deadlines for all grant application materials are February 1st and September 20th of each year. Applications and detailed information are available at <www.primate.org/grant_in.htm>. You may send questions to Noel Rowe [e-mail: nrowe@primate.org].

Heart/Lung Transplantation Tolerance

The National Institute of Allergy and Infectious Diseases (NIAID) invites applications from single institutions or consortia of institutions to participate in the Non-Human Primate Immune Tolerance Cooperative Study Group (NHPCSG). The NHPCSG is a multi-center, cooperative program for research on nonhuman primate (NHP) models of kidney and islet transplantation, established in 1999 to evaluate preclinical safety and efficacy of existing and newly developed immune tolerance induction regimens and to elucidate the underlying mechanisms of the induction, maintenance, and/or loss of tolerance in these models. The long-range goal of this program is to develop and evaluate tolerance-induction regimens that will result in enhanced long-term graft survival in clinical transplantation of all organs and tissues. The purpose of this Request for Applications (RFA) is to expand the scope of transplantation models studied within the NHPCSG to include NHP models of heart and lung transplantation.

The goals of the NHPCSG include:

1. development of novel donor-specific tolerance induction regimens;
2. assessment of the safety and efficacy of existing and newly developed immune tolerance regimens in preparation for human clinical trials;
3. definition of underlying mechanisms of action of the therapeutic approaches under investigation and the mechanisms of induction, maintenance and/or loss of tolerance; and
4. development and validation of biomarkers for the induction, maintenance and/or loss of immune tolerance.

This RFA solicits grant applications to expand the scope of the current NHPCSG to include immune tolerance induction studies in NHP models of heart and lung transplantation. Currently the NHPCSG is funded exclusively for studies in islet and kidney transplantation. Because the long-range goal of this RFA is to develop and evaluate candidate tolerogenic approaches for transplantation in humans, NIAID expects that there will be reciprocal communication between the NHPCSG and NIH-funded clinical trials programs. In addition, this interaction may result in potential opportunities to develop and participate in initial safety and efficacy pre-clinical studies.

All research projects to be supported under this RFA are limited to NHP heart and/or lung transplantation models. Specifically, this RFA calls for the use of any NHP species for allogeneic studies of heart and/or lung transplantation. While individual research approaches may vary, the research scope of applications is restricted to one or more of the following areas:

1. development of novel donor-specific tolerance induction regimens or refinement of existing regimens;
2. assessment of the safety and/or efficacy of existing or newly developed immune tolerance regimens either alone, in combination with immunosuppressive therapy, and/or in combination with withdrawal of immunosuppressive therapy;
3. studies to define the underlying mechanisms of action of the therapeutic approaches under investigation, including changes in immune response and function, and the mechanisms of induction, maintenance and/or loss of donor-specific tolerance; and
4. studies to develop, evaluate, and validate biomarkers for the induction, maintenance, and/or loss of immune tolerance, and/or for onset of acute or chronic graft rejection.

Anatomy and Physiology

* Hibernation in a tropical primate. Kausmann, K. H., Glos, J., Ganzhorn, J. U., & Heldmaier, G. (Dept of Animal Physiology, Phillips Univ., 35043 Marburg, Germany [e-mail: dausmann@staff.uni-marburg.de]). Nature, 2004, 429, 825-826.
. . . The Madagascan fat-tailed dwarf lemur, Cheirogaleus medius, hibernates in tree holes for seven months of the year, even though winter temperatures rise to over 30°C. Here it is shown that this tropical primate relies on a flexible thermal response that depends on the properties of its tree hole: if the hole is poorly insulated, body temperature fluctuates widely, passively following the ambient temperature; if well insulated, body temperature stays fairly constant and the animal undergoes regular spells of arousal. The findings indicate that arousals are determined by maximum body temperatures and that hypometabolism in hibernating animals is not necessarily coupled to a low body temperature.

* Footfall patterns, stride length and speed of vertical climbing in spider monkeys (Ateles fusciceps robustus) and woolly monkeys (Lagothrix lagotricha). Isler, K. (Anthropologisches Institut und Museum, Universität Zürich-Irchel, Winterthurerstrasse 190, CH.8057 Zürich, Switzerland [e-mail: kisler@aim.unizh.ch]). Folia Primatologica, 2004, 75, 133-149.
. . . Vertical climbing is central to theories surrounding the locomotor specializations of large primates. This paper presents spatiotemporal gait parameters obtained from video recordings of captive spider monkeys and woolly monkeys in semi-natural enclosures, with the aim of discovering the influence of body weight and differences in general locomotor behavior on vertical climbing kinematics on various substrates. There are few differences between gait parameters of climbing on thin trees, vertical and oblique ropes, while climbing on large-diameter trees differs considerably, reflecting the higher costs of locomotion on the latter. At the same speed, Ateles takes longer strides and the support phase takes a smaller percentage of cycle duration than in Lagothrix. Footfall patterns are more diverse in Ateles and include a higher proportion of ipsilateral limb coupling. Compared to other primates, the gait characteristics of vertical climbing of atelines most closely resemble those of African apes.

* Brain structure variation in great apes, with attention to the mountain gorilla (Gorilla beringei beringei). Sherwood, C. C., Cranfield, M. R., Mehlman, P. T., Lilly, A. A., Garbe, J. A. L., Whittier, C. A., Nutter, F. B., Rein, T., R., Bruner, H. J., Holloway, R. L., Tang, C. Y., Naidich, T. P., Delman, B. N., Steklis, H. D., Erwin, J. M., & Hoff, P. R. (Department of Anthropology, Kent State University, 226 Lowry Hall, Kent, OH 44242-0001 [e-mail: csherwoo@kent.edu]). American Journal of Primatology, 2004, 63, 149-164.
. . . “Magnetic resonance (MR) images of three mountain gorilla brains were obtained with a 3T scanner, and the volume of major neuroanatomical structures (neocortical gray matter, hippocampus, thalamus, striatum, and cerebellum) was measured. These data were included with our existing database that includes 23 chimpanzees, three western lowland gorillas, and six orangutans. We defined a multidimensional space by calculating the principal components (PCs) from the correlation matrix of brain structure fractions in the well-represented sample of chimpanzees. We then plotted data from all of the taxa in this space to examine phyletic variation in neural organization. Most of the variance in mountain gorillas, as well as other great apes, was contained within the chimpanzee range along the first two PCs, which accounted for 61.73% of the total variance. Thus, the majority of interspecific variation in brain structure observed among these ape taxa was no greater than the within-species variation seen in chimpanzees. The loadings on PCs indicated that the brain structure of great apes differs among taxa mostly in the relative sizes of the striatum, cerebellum, and hippocampus. These findings suggest possible functional differences among taxa in terms of neural adaptations for ecological and locomotor capacities. Importantly, these results fill a critical gap in current knowledge regarding great ape neuroanatomical diversity.”

* Personality characteristics and basal cortisol concentrations in adult male rhesus macaques (Macaca mulatta). Capitanio, J. P., Mendoza, S. P., & Bentson, K. L. (Dept of Psychology, Univ of California, Davis, CA 95616-8686 [e-mail: jpcapitanio@ucdavis.edu]). Psychoneuroendocrinology, 2004, 29, 1300-1308.
. . . “Although data show that psychosocial factors can regulate physiological processes, few data have been collected on normative populations. Studies in humans have suggested that personality characteristics might be related to regulation of the hypothalamic-pituitary-adrenal (HPA) axis. We explored the relationship between personality characteristics and plasma cortisol concentrations in adult male rhesus macaques. Two sets of blood samples were obtained from monkeys using a procedure with which they were very familiar; thus, cortisol concentrations reflected basal values. Analyses indicated high-excitable animals had lower basal cortisol concentrations during the afternoon period, and that low-confidence was associated with lower cortisol in the morning period and lack of a circadian decline in the afternoon period. Sociability and equability were unrelated to cortisol levels. Our data confirm and extend some results found in human studies, and suggest that even in normal populations, personality characteristics are related to measures of HPA function. We propose that comparative studies of personality in nonhuman primates that parallel studies in humans can increase our understanding of mechanisms whereby personality may relate to mental and physical health outcomes.”

Animal Models

* Cyclophilin A retrotransposition into TRIM5 explains owl monkey resistance to HIV-1. Sayah, D. M., Sokolskaya, E., Berthoux, L., & Luban, J. (J. L., Dept of Med., Columbia Univ., College of Physicians and Surgeons, 701 West 168th St, HHSC 1502, New York, NY 10032 [e-mail: jl45@columbia.edu]). Nature, 2004, 430, 569-573.
. . . “In Old World primates, TRIM5-a confers a potent block to human immunodeficiency virus type 1 (HIV-1) infection that acts after virus entry into cells. Cyclophilin A (CypA) binding to viral capsid protects HIV-1 from a similar activity in human cells. Among New World primates, only owl monkeys exhibit post-entry restriction of HIV-1. Paradoxically, the barrier to HIV-1 in owl monkey cells is released by capsid mutants or drugs that disrupt capsid interaction with CypA. Here we show that knockdown of owl monkey CypA by RNA interference (RNAi) correlates with suppression of anti-HIV-1 activity. However, reintroduction of CypA protein to RNAi-treated cells did not restore antiviral activity. A search for additional RNAi targets unearthed TRIMCyp, an RNAi-responsive messenger RNA encoding a TRIM5-CypA fusion protein. TRIMCyp accounts for post-entry restriction of HIV-1 in owl monkeys and blocks HIV-1 infection when transferred to otherwise infectable human or rat cells. It seems that TRIMCyp arose after the divergence of New and Old World primates when a LINE-1 retrotransposon catalysed the insertion of a CypA complementary DNA into the TRIM5 locus. This is the first vertebrate example of a chimaeric gene generated by this mechanism of exon shuffling.”

* Highly pathogenic SHIVs and SIVs target different CD4+ T cell subsets in rhesus monkeys, explaining their divergent clinical courses. Nishimura, Y., Igarashi, T., Donau, O. K., Buckler-White, A., Buckler, C., Lafont, B. A. P., Goeken, R. M., Goldstein, S., Hirsch, V. M., & Martin, M. A. (M. A. M., Lab. of Molecular Microbiology, National Inst. of Allergy & Infectious Diseases, NIH, Bethesda, MD 20892 [e-mail: mmartin@niaid.nih.gov]). Proceedings of the National Academy of Sciences, U.S.A., 2004, 101, 12324-12329; freely available online through the PNAS open access option.
. . . In contrast to simian immunodeficiency viruses (SIVs), which induce immunodeficiency over a 1- to 3-year period, highly pathogenic simian-human immunodeficiency viruses (SHIVs) cause a complete, irreversible, and systemic depletion of CD4+ T lymphocytes in rhesus monkeys within weeks of infection. By using small-molecule competitors specific for CCR5 and CXCR4 in ex vivo assays, we found that highly pathogenic SHIV(DH12R) exclusively uses CXCR4 for infection of rhesus peripheral blood mononuclear cells, whereas SIV(mac239) and SIV(smE543) use CCR5 for entry into the same cells. During the period of peak virus production in SHIVDH12R)- or SHIV(89.6P)-infected rhesus monkeys, massive elimination of CXCR4+ naïve CD4+ T cells occurred. In contrast, circulating CCR5+ memory CD4+ T cells were selectively depleted in rapidly progressing SIV-infected monkeys. At the time of their death, two SIV rapid progressors had experienced a nearly complete loss of the memory CD4+ T cell subset from the blood and mesenteric lymph nodes. Thus, pathogenic SHIVs and SIVs target different subsets of CD4+ T cells in vivo, with the pattern of CD4+ T lymphocyte depletion being inextricably linked to chemokine receptor use. In the context of developing an effective prophylactic vaccine, which must potently control virus replication during the primary infection, regimens that suppress SHIVs might not protect monkeys against SIV or humans against HIV-1.

* Use of primates in research: A global overview. Carlsson, H.-E., Schapiro, S. J., Farah, I., & Hau, J. (Div. of Comp. Med., Dept of Neuroscience, BMC Box 572, Uppsala Univ., SE-751 23 Uppsala, Sweden [e-mail: Hans-Erik.Carlsson@bmc.uu.se]). American Journal of Primatology, 2004, 63, 225-237.
. . . The use of nonhuman primates and nonhuman primate biological material in research was assessed by reviewing studies published in 2001 in peer-reviewed journals. The number and species of primates used, the origin of the animals, the type of study, the area of research of the investigation, and the location at which the research was performed were tabulated. Additionally, factors related to the animals that may have affected the outcome of the experiments were recorded. A total of 2,937 articles involving 4,411 studies that employed nonhuman primates or nonhuman primate biological material were identified and analyzed. More than 41,000 animals were represented in the studies published in 2001. In the 14% of studies for which re-use could be determined, 69% involved animals that had been used in previous experiments. Published studies most commonly used nonhuman primates or nonhuman primate biological material from the species Chlorocebus aethiops (19%), Macaca mulatta (18%), M. fascicularis (9%), and Papio spp. (6%). Of these studies, 54% were classified as in vitro studies, 14% as noninvasive, 30% as chronic, and 1% were considered acute. Nonhuman primates were primarily used in research areas in which they appear to be the most appropriate models for humans. The most common areas of research were microbiology (including HIV/AIDS (26%)), neuroscience (19%), and biochemistry/chemistry (12%). Most (84%) of the primate research published in 2001 was conducted in North America, Europe, and Japan. The animals and conditions under which they were housed and used were rarely described. Although it is estimated that nonhuman primates account for an extremely small fraction of all animals used in research, their special status makes it important to report the many husbandry and environmental factors that influence the research results generated. This analysis has identified that editors rarely require authors to provide comprehensive information concerning the subjects (e.g., their origin), treatment conditions, and experimental procedures utilized in the studies they publish. The present analysis addresses the use of primates for research, including the effects of a shortage of suitable nonhuman primate subjects in many research areas.

Animal Welfare

* Short and long-term effects of a substantial change in cage size on individually housed, adult male rhesus monkeys (Macaca mulatta). Kaufman, B. M., Pouliot, A. L., Tiefenbacher, S., & Novak, M. A. (M. A. N., Psych. Dept, Univ. Mass., 439 Tobin Hall, 135 Hicks Way, Amherst, MA 01003 [e-mail: mnovak@psych.umass.edu]). Applied Animal Behaviour Science, 2004, 88, 319-330.
. . . An investigation of the effects of a six-fold increase in cage size on the behavior of individually housed male rhesus monkeys. Limitations of previous studies included the magnitude of change in cage size, the length of the observation period, and the potential confounds of relocation. Prior to this study, eight male monkeys were individually housed in pens (6.77 cu-m) for varying lengths of time before moving to baboon cages (1.24 cu-m) located within their pens. After 2 years in baboon cages, monkeys were returned to their pen environment (6.77 cu-m). Monkeys were observed for forty 5-min observation periods representing four phases: short (first 4 months) and long-term (after 23 months) exposure to the baboon cage followed by short (first month) and long-term (after 8 months) exposure to the pen environment. Contrary to expectations, general activity decreased and abnormal behavior remained unchanged when the monkeys were returned to their pens. However, tension-related behavior decreased significantly with exposure to a larger cage. The results of this study suggest that cage size does not have a detectable impact on habitual kinds of abnormal behavior but may significantly affect the level of tension.

* A study of behavioural responses of non-human primates to air transport and re-housing. Honess, P. E., Johnson, P. J., & Wolfensohn, S. E. (Dept of Vet. Services, Univ. of Oxford, OX1 3PT, U.K. [e-mail: paul.honess@vet.ox.ac.uk]). Laboratory Animals, 2004, 38, 119-132.
. . . More long-tailed macaques (Macaca fascicularis) than any other primate are imported into the U.K. for research, and journey times may be of up to 58 h. While a number of studies have examined the stress associated with transport, these have typically involved laboratory rodents and livestock, and little is known of its effect on nonhuman primates. This paper reports the results of a study of behavioral changes in a group of long-tailed macaques transported by air from standard breeding conditions and then re-housed in standard laboratory primate conditions. The animals were studied prior to their departure, immediately after arrival, and 3 weeks after that. Data were collected on individual time budgets using focal animal sampling and on hierarchy using a feeding trial. The data were analyzed for changes in behavioral repertoires and for social perturbation that would be reflected in hierarchical changes. Changes in behavior occurred which reflected heightened levels of stress in the study group. It was also clear that although there was some adjustment of behavior, after an initial change on arrival at the new establishment, there was no return to levels observed at the breeding facility within the first month. This study demonstrates that, as a whole, the process of international air transport and re-housing in laboratory conditions may result in the compromising of the welfare of the study animals.

Behavior

* Long-distance calls in Neotropical primates. Oliveira, D. A. G., & Ades, C. (R. Anfilofio de Carvalho, 29, 3. and. 20030-060 Rio de Janeiro RJ Brazil [e-mail: dilmar@usp.br]). Anais da Academia Brasileira de Ciências, 2004, 76, 393-398.
. . . Long-distance calls are widespread among primates. Several studies concentrate on such calls in just one or in few species, while few studies have treated more general trends within the order. The common features that usually characterize these vocalizations are related to long-distance propagation of sounds. The proposed functions of primate long-distance calls can be divided into extragroup and intragroup ones. Extragroup functions relate to mate defense, mate attraction or resource defense, while intragroup functions involve group coordination or alarm. Among Neotropical primates, several species perform long-distance calls that seem more related to intragroup coordination, markedly in atelines. Callitrichids present long-distance calls that are employed both in intragroup coordination and intergroup contests or spacing. Examples of extragroup-directed long-distance calls are the duets of titi monkeys and the roars and barks of howler monkeys. Considerable complexity and gradation exist in the long-distance call repertoires of some Neotropical primates, and female long-distance calls are probably more important in non-duetting species than usually thought. Future research must focus on larger trends in the evolution of primate long-distance calls, including the phylogeny of calling repertoires and the relationships between form and function in these signals.

* Vocal sequential exchanges and intragroup spacing in the northern muriqui Brachyteles arachnoides hypoxanthus. Mendes, F. D. C., & Ades, C. (address same as above [e-mail: francisco@ucg.br]). Anais da Academia Brasileira de Ciências, 2004, 76, 399-404.
. . . Sequential exchanges of vocalizations (staccatos and neighs) emitted by northern muriquis were recorded at the Biological Station of Caratinga, Minas Gerais State, Brazil. Staccatos and neighs containing a larger proportion of short elements were preferentially produced during short-range exchanges; neighs, produced by a larger number of participants, were typical of long-range exchanges. Staccatos emitted by animals feeding in a dispersed manner contained a larger proportion of tonal elements than those emitted by muriquis feeding in a cohesive manner. Sequential exchanges seem thus to be constituted by two interrelated subsystems of calls that aid muriquis to coordinate intragroup spacing, despite the poor visibility of the habitat.

* Cognitive imitation in rhesus macaques. Subiaul, F., Cantlon, J. F., Holloway, R. L., & Terrace, H. S. ((Dept of Anthropology, Columbia Univ., New York, NY 10027 [e-mail: subiaul@aol.com]). Science, 2004, 305, 407-410.
. . . Experiments on imitation typically evaluate a student’s ability to copy some feature of an expert’s motor behavior. Here, we describe a type of observational learning in which a student copies a cognitive rule rather than a specific motor action. Two rhesus macaques were trained to respond, in a prescribed order, to different sets of photographs that were displayed on a touch-sensitive monitor. Because the position of the photographs varied randomly from trial to trial, sequences could not be learned by motor imitation. Both monkeys learned new sequences more rapidly after observing an expert execute those sequences than when they had to learn new sequences entirely by trial and error.

* An experimental study of leaf swallowing in captive chimpanzees: Insights into the origin of a self-medicative behavior and the role of social learning. Huffman, M. A., & Hirata, S. (Primate Research Inst., Kyoto Univ., 41-2 Kanrin, Inuyama, Aichi 484-8506, Japan [e-mail: huffman@pri.kyoto-u.ac.jp]). Primates, 2004, 45, 113-118.
. . . Chimpanzees in the wild swallow the rough hispid leaves of certain plant species as a means of physically expelling intestinal parasites. A plant with such a leaf texture was introduced in 36 trial sessions to a captive group of 11 healthy adult chimpanzees to investigate the possible origin and acquisition of leaf swallowing behavior. One male (housed separately from the group during testing) and one female, both captive born, spontaneously exhibited the behavior on their first trial without prior opportunity to observe others with this plant. Six other chimpanzees on their first trial displayed a phobic response to these leaves and rejected them entirely, while another two chewed and swallowed the leaves in a normal way. Four individuals eventually exhibited the behavior, after having approached and closely observed the leaf swallowing of the first female to exhibit the behavior in the group. Four of the six individuals that initially avoided the leaves never overcame their phobia toward this plant and were not in proximity to a chimpanzee performing leaf swallowing during test sessions. Individuals born to wild chimpanzee mothers were no more likely to perform the behavior than captive-reared group mates. These results suggest that the acquisition of this behavior is based in part on a propensity to fold and swallow rough, hispid leaves, but that the acquisition and spread of leaf swallowing within a group is likely to be socially influenced. This study provides support for the hypothesis that leaf swallowing originated in the wild from opportunistic feeding behavior and was later passed down in the form of a self-medicative behavioral tradition.

* Extinction deficits in male rhesus macaques with a history of self-injurious behavior. Lutz, C., Tiefenbacher, S., Meyer, J., & Novak, M. (Harvard Med. School, New England PRC, One Pine Hill Dr., P. O. Box 9102, Southborough, MA 01772-9102 [e-mail: Corrine_Lutz@hms.harvard.edu]). American Journal of Primatology, 2004, 63, 41-48.
. . . Self-injurious behavior (SIB) occurs in both human and nonhuman primate populations. Despite the potential for harm, SIB may persist in part because of an inability to inhibit behavior that results in wounding. A lever-pressing task was used to test the prediction that monkeys with SIB would show greater persistence in lever-pressing on extinction trials than monkeys without the disorder. The subjects were 15 individually housed adult male rhesus macaques, 10 of which (the SIB group) had a veterinary record of self-inflicted wounding. All of the monkeys were trained to lever-press for food rewards to a criterion of 400 total responses. The test procedures consisted of five daily 30-min sessions divided into six 5-min intervals. On day 1, the subjects received continuous reinforcement. On days 2-4, testing consisted of alternating reinforced/unreinforced 5-min intervals, beginning with reinforcement. Reinforced intervals were cued with a buzzer. On day 5, the subjects received no reinforcement. The number of lever-presses and behavioral responses were recorded during each session. Saliva samples were collected for cortisol measurement before and after test sessions on days 1, 2, and 5. As predicted, monkeys with SIB lever-pressed more than controls during extinction intervals on days 2-4. There was no difference on day 1 or day 5. The frequency of scratching, yawning, and abnormal behavior increased when reinforcement was intermittent (days 2-4) or absent (day 5). Cortisol levels were highest with continuous reinforcement (day 1), and may reflect differential levels of food intake rather than stress. The presence of extinction deficits suggests that SIB may persist in some monkeys because they lack the ability to regulate the intensity of their biting behavior.
