Retrospective Study of the Causes of Infant Death in a Common Marmoset
(Callithrix jacchus jacchus) Colony
Guillermo Rico Hernández and Alberto Parás García
Africam Safari
Introduction
Callitrichids are small, diurnal South American primates (infraorder Platyrrhini; family Callitrichidae). They weigh less than one kilogram, have a characteristic nonprehensile tail, and are highly adapted to arboreal life. For example, they have claws, which allow them to climb trees much like squirrels (Rowe, 1996).
Free ranging individuals live in secondary forest in which they forage for insects and fruit and seek shelter (Rowe, 1996). Despite being highly adaptable, callitrichids are delicate and require careful management in captivity for proper reproduction and development (Montali & Bush, 1999).
Even though the International Union for Conservation of Nature (IUCN) does not list the common marmoset (Callithrix jacchus jacchus) as endangered, its study in captivity is important, because two other species of Callithrix are endangered. C. jacchus is a useful model for the reproduction and management of its threatened and endangered relatives.
Several callitrichid species have proved to be valuable biomedical models in different research areas; many of their biological and behavioral characteristics have been well defined. They are susceptible to oncogenic viruses and infectious hepatitis, as well as viral diseases such as rubella and hematopoietic chimerism, which are important in immunological research. Consequently, there is a great demand for captive colonies of callitrichids (Wolfe et al., 1975; Box, 1995). Callitrichids are also relatively inexpensive to maintain because of their small size (Wolfe et al., 1975).
Common marmosets breed easily in captivity. Female estrous cycles last 16.4 days; the gestation period is 148 ñ 4.7 days, with two or three offspring commonly delivered. In captivity, interbirth intervals are six months, although intervals of one year have been reported, resembling those of free ranging animals. Females wean their offspring between 31 and 90 days after birth. A study of Africam Safari's colony of common marmosets found a gestation period of 160 days, an interbirth interval ranging from 151 to 164 days, and no birth seasonality (Serio Silva et al., 2000).
Females do not menstruate, and in captivity mate frequently throughout their cycle, having no behavioral or external signs of estrus. Callitrichids do not have lactational anestrus: in fact, conception may occur during the postpartum period. Females reach sexual maturity at 20 to 24 months, while males reach it from 9 to 13 months (e.g., Hearn, 1977; Johnson et al., 1991).
Callitrichid groups are larger than typical monogamous primate families. They have an unusual cooperative breeding system, in which offspring stay within family groups into adulthood, helping to rear new litters of the dominant pair (e.g., Abbott & George, 1991; Box, 1995).
In captivity, breeding pairs mate even after their offspring reach sexual maturity. In family groups, sons are subordinate to their father, showing little reproductive behavior; although in certain circumstances they mount their sisters and mother, without penetration or ejaculation (Abbott, 1993).
Captive callitrichids may suffer infectious and noninfectious diseases that must be controlled or prevented (Montali, 1994; Potkay, 1992). In some nonhuman primate colonies, prenatal mortality may exceed 15% of diagnosed pregnancies (Bunton, 1986).
Because of the economic importance of callitrichids in research and education, more biological and medical data are needed to minimize maintenance and mortality problems. Both conservation and animal welfare must be considered in establishing colonies (Box, 1995).
This retrospective study examines causes of infant death from 1991 to 1999 in the common marmoset colony at Africam Safari. Factors that were evaluated include: age, litter composition, dam's rank in hierarchy and her reproductive experience, group size, enclosure site, and seasonality of deaths.
Material and Methods
The common marmoset colony at Africam Safari was established in February, 1988, with four males and four females; the first litter was born in September, 1989. The average litter has been one or two offspring, but occasionally three or four (Serio Silva et al., 2000).
The colony is kept in two different sections of the zoo. Section A is public, with a great many visitors. This enclosure is about 16 m2. Section B is off display and includes three enclosures of 18 m2 each. All enclosures are constructed of metal and wire mesh and have a grass floor, behavioral enrichment structures, and an artificial heat source. Pathology records of all common marmosets that died during the nine-year period from 1991 through 1999 were reviewed. Following the methodology of Rothe et al. (1992), the data were classified according to age at death: 0 days (abortions and stillbirths), animals which died or were killed within 1 day, 2 to 7 days, 8 to 30 days, and 31 to 150 days. Rank in hierarchy and parity of the mothers, litter composition, and annual and enclosure distribution were analyzed, along with the causes of deaths.
Results
Twenty-six infant deaths were analyzed (Table 1). The causes of death were: reproductive problems (abnormal delivery, abortion, stillbirth), rearing problems (hand rearing problems, starvation, failure to thrive), pneumonia, and trauma (due to aggression by conspecifics, entrapment by some feature of the enclosure, or falling from a caretaker). 92.3% of the deaths occurred within the first month of age.

Table 1: Ages and causes of death.
Reproductive problems caused eight (30.8%) of the infant deaths; six were abortions or stillbirths, the other two were of one-day-olds. Rearing problems caused 10 (38.5%) deaths, all of 1-to-30-day-olds.
One (3.8%) 2-to-7-day old infant died of pneumonia.
Trauma resulted in seven (26.9%) deaths, and was responsible for both 31-150-day-olds' deaths (one caused by an enclosure feature and one by a conspecific). Three one-day-old infants died of trauma, one from a conspecific and two by falling. Conspecific trauma caused two deaths in 8-to-30-day-old individuals.

Table 2: Infant deaths and mothers' position in hierarchy and parity.
Most (11/18) of the 1-to-30-day-olds who died were offspring of subordinate females (Table 2). However, both 31-to-150-day-olds who died were offspring of dominant females. Four of six 1-day-olds, one of six 2-to-7-day-olds, and one of six 8-to-30-day-olds were also offspring of dominant females. The dominance status of the mother of one 2-to-7-day-old had not been recorded.
Seven of the 11 infants that died within the first week of life had primiparous mothers; as did all six 1-day-olds (Table 2).
Fourteen (53.8%) deaths were twins: one from a male-male pair; one from a male-unsexed pair; and 12 (46%) from male-female pairs. All 1-day-old and 31-to-150-day-olds who died were born in male-female pairs. All the infants in the sole quadruple litter died.
Six (23.1%) and four (15.4%) deaths were observed in May and March respectively, while there were only one or two deaths in any of the remaining months. In the first half of the study period, 18 of the 26 infant deaths occurred.
Twenty (76.9%) infant deaths occured in B section (off display). All 0-day-old and 2-to-7-day-old deaths were in that section.
Discussion
Many species of captive mammals show more deaths before weaning than in other stages of life. As in other callitrichid colonies (Kilborn et al., 1983; Rothe et al., 1992; Jaquish et al., 1997), most infant deaths in our study occurred in the first week of life. Several factors affecting infant survival are: population density, availability of food, birth seasonality, birth weight, litter size, parental care, and social environment. When studying captive populations, it is necessary to look at all of these factors (Jaquish et al., 1997).
Bunton (1986) mentioned that prenatal mortality in nonhuman primates may exceed 15% of all diagnosed pregnancies. In our study abortions and stillbirths were 23.1% of infant deaths. Potential causes of abortions in nonhuman primates - and in many other mammals - are genetic factors, developmental malformations, ischemic lesions of the placenta, trauma, infections, and hormonal aberrations (King & Chalifoux, 1986). Both maternal stress and infections are important causes of stillbirth. In nonhuman primates, and even in man, ascendent genital infections are responsible for placentitis and subsequent anoxia and fetal death (Andrews, 1974).
Deaths caused by failure to thrive were correlated with hierarchy and parity of the mother and subsequent starvation and hand rearing problems. Some captive callitrichid infants have little chance of survival; to save them, it is necessary to develop an effective hand rearing protocol (See, e.g., Patiño & Borda, 1997; Patiño et al., 1997).
Traumas mainly occurred within the first month of life. Intragroup aggression in callitrichids generally occurs soon after the birth of infants and following removal of families or individuals from one enclosure to another (Box & Hubrecht, 1987). In 1-day-olds, two of the three deaths were caused by infants falling from their mothers - both of whom were subordinate and/or primiparous, lacking maternal experience and conspecific help.
Conspecific trauma, (which represents 15.4% of infant deaths, and which often involved biting), enclosure trauma, and cerebral trauma from falling (commonly associated with maternal neglect) could not only be considered in conjunction with hierarchy and female reproductive experience, but also with different social and environmental factors that could intensify intragroup aggression. Experiments to determine effects of cohesion, social composition, and behavioral changes should help predict these incidents and thus avoid high and persistent aggression levels (Box & Hubrecht, 1987).
There was only one death caused by enclosure trauma: a 31-to-150-day-old individual found trapped between two branches. It is important to provide a safe enclosure with appropriate environmental elements to ensure natural development in the colony. In callitrichids different captive regimens affect behaviors, so it would be useful to evaluate animals under different conditions that might minimize deaths (Box, 1995).
Reproductive biology of females is influenced by social environment. In callitrichids, dominant females are the only troop members that are actively reproductive; they struggle to maintain this status. Subordinate females have their ovarian cycles suppressed and also have detectable estrogens and LH (luteinizing hormone) levels while staying with their family group. This is known as fertility suppression. Subordinate captive females have difficulty reversing suppression unless they are removed from their family group. Nevertheless, in our colony subordinate females gave birth. The possibility for ovulating and mating of a subordinate female is influenced by her relationship with the dominant female. Those daughters with more tolerant and less aggressive mothers may develop a better relationship and consequently have more opportunity to escape from suppression. In intact family groups, this phenomenon is associated with fewer social interaction changes (Saltzman et al., 1997).
In this common marmoset colony, reproductive groups have always been harem-like, in which the young help care for their siblings. Both sections A and B have well-defined dominant pairs with a periodic reproductive pattern. Thus, with enclosure management, group hierarchy has been relatively constant. Under captive conditions no significant correlation between group size and infant survival rate has been seen (Johnson et al., 1991; Rothe et al., 1993); furthermore, it has been suggested that helpers are not required in captivity where food is supplied (Rothe et al., 1993). However, in our data 11 (42.3%) infant deaths were offspring of subordinate mothers and died within the first month of life; surely no helpers were available for their mothers.
Similarly, more deaths occurred in offspring of primiparous mothers, whether dominant or subordinate. This parity effect has been noted in other colonies. In cotton-top tamarins (Saguinus oedipus, see Johnson et al., 1991) and saddleback tamarins (S. fuscicollis, see Tirado Herrera et al., 2000), infants of primiparous parents had a higher rejection and a lower survival rate. Captive primiparous females often kill and devour their offspring. The number of older offspring helping with rearing, the parity and experience of the breeding pair, and the collaboration of males in rearing their young are all factors that are associated with less rejection of the young in captivity. The deaths of dominant females' offspring were associated with their primiparity.
In our colony, hierarchy was defined by behavioral and reproductive evaluation. Females who regularly mated and gave birth to viable offspring were considered dominant. In order to confirm their dominant status, LH and estrogen levels in serum, feces, and/or urine could be analyzed.
Our colony consisted of established families with siblings sharing care of offspring; low infant mortality would be predicted compared with other colonies where offspring are separated from their parents when they reach puberty (Johnson et al., 1991). In captivity, it is advisable to let offspring stay with their parents until the next litter has been born and weaned. Even if the breeding pair cares for the first litter, the parents will abandon a second litter, forcing members of the first litter to care for their siblings. The result of such a social structure could be that individuals learn complex species-typical reproductive behavior (Hearn, 1977).
More deaths were observed in twin litters. All individuals from the quadruplet litter died. In captive populations the amount and quality of food are quite constant throughout the year. In litters of more than two, the mother has an increased metabolic cost due to lactation; hence, maternal milk supply would be one of the limiting factors in the number of infants that can be reared. Therefore, these deaths could be attributed to lack of nutrition. The quadruplet litter was from a subordinate multiparous female, so these deaths could also be attributed to the mother's status in the hierarchy. High perinatal mortality is a significant problem in captive populations of most callitrichids, more often in triplets and quadruplets than in twins, due to subsequent rearing difficulty. However improving environmental and nutritional conditions might improve offfspring survival (Kilborn et al.,1983; Box & Hubrecht, 1987; Jaquish et al., 1997).
A and B sections had similar husbandry conditions and social composition. Yet twenty (76.9%) of the 26 infant deaths ocurred in B section, which is off display for visitors. The only death caused by pneumonia, commonly associated with viral and bacterial agents, was in this section.
Common marmosets were born in every month of the year. A spring peak of births, similar to that in the wild, was observed in this and other captive colonies of marmosets (see Kilborn et al., 1983), possibly associated with photoperiod. Kilborn also observed an increase in deaths during the first halves of each year.
As we suggested previously, it is important to provide environmental enrichment and a social composition similar to that in nature, to encourage good health and reproduction. Captive callitrichid mortality may diminish radically through improved methods of care and maintenance (Box et al., 1987; Kelly, 1993).
Environmental factors, such as food availability, weather, social composition, and enclosure quality, regulate reproductive success and offspring survival by generating metabolic, behavioral, and reproductive changes.
Further studies in this colony should establish the precise hierarchy and enable evaluation of how variations in habitat quality (e.g., population density and group size) may affect offspring survival, bearing in mind that the most stimulating aspects of an animal's environment are determined by conspecifics (Van Hoof, 1986).

Marking Monkeys - Nyanzol-D
In March, Gerald Ruppenthal Nancy Megna Rich Rawlins (A possible testimonial might be obtained from Steve Schapiro Editors' notes: Steve says that he *did* wash during the six or more weeks that the dye stayed on. We believe him. We also did a Web search for "Nyanzol-D" and found that the British Columbia Resources Inventory Committee and the Canadian Council on Animal Care recommend it for snowshoe hare, and the U.S. National Park Service for prairie dog identification. We also found reference to its use on rhesus monkeys aged 5 months to 21 years, in C. M. Drea & K. Wallen (1999) ["Low status monkeys 'play dumb' when learning in mixed social groups." Proceedings of the National Academy of Sciences, 96, 12965-12969].
Hope Walker, of the Primate Conservation & Welfare Society (PCWS), wrote to the Primate Enrichment Forum The resulting discussion went on from April 24 to May 12. The discussants included Rita Bellanca, of the Washington RPRC; Jen Feuerstein and Brooke Wurrey, professional primate keepers; David Seelig, who is working at Brandeis University this year; Cobie Brinkman, of the Australian National University; Katie Eckert, of the University of California, San Francisco; and Sue Johnson, of the Sacramento Zoo.

Rita, Jen, and David suggested using peanut butter, marmalade, or honey. Rita offered: "smear peanut butter or a water/flour paste on the tubes and roll them in cereals, coconut. Stuff them with marmalade, honey, or peanut butter and some fruits or vegetables and fold the ends shut. Note: We usually freeze our creations; those may not work well without freezing." David thought peanut butter would "give the primates something to do with the cardboard once they get everything on the inside out." Jen also suggested cereals, raisins, other dried fruits, uncooked pasta, mini-marshmallows, shredded coconut, popcorn (popped of course!), mini-pretzels, animal crackers, etc., mixed with shredded paper in the tubes.
Katie wrote: "I'm curious about the use of peanut butter and cardboard: don't the monkeys or apes just eat the cardboard if it's got sticky stuff on it? We've tried it here and had bad results with one macaque. Also, I would think that if you used natural peanut butter (no added sugar), it would tend to go bad." And Rita replied: "Our macaques and baboons tend to lick the peanut butter or honey off the cardboard, and then shred the cardboard and/or toss it aside. A few do swallow small pieces, but we've had no health problems related to this. Has anyone else had problems with animals eating cardboard?"
Hope then said she would appreciate any additional suggestions in which sugar and salt are not included. And David wrote: "A couple of people wrote to me, disagreeing with giving primates peanut butter (or sweet things like honey) as enrichment. I feel that anything is okay in moderation, but perhaps it is better not to give salty things or simple carbohydrates at all, as the primates come to expect them. Once when I was working with a social group of pigtails, I gave one of the juveniles a piece of candy. I doubt he had ever had refined sugar before, and he really liked it! For the next several weeks, if he saw me approach he would chase all of the subordinates away on the off chance he would get another piece, though I didn't reinforce this behavior at all. I regretted giving him the candy, because since such things can't be given daily (for health and practical reasons) - I wasn't sure if the enjoyment he got out of eating the candy balanced out all the time he probably missed having it.
"It's an interesting question: should primates be given jam, peanut butter, honey, molasses, and other sweet and salty things in moderation or not at all? Or perhaps these things should only be given when giving doses (e.g., putting medicine in a marshmallow or fruit juice)? What do you all think?"
Cobie wrote: "I never used sugary foods for my pigtails and cynos for environmental enrichment purposes because of the risk of tooth decay, to which some macaques are very vulnerable (which is why they are an animal model of it!), and of resulting gum disease. We gave a variety of fruits and vegetables - whatever was seasonal - and browse like lucerne (alfalfa) and foliage. Apples were given daily. They also had wooden chewing blocks. Under this regimen, very little cleaning was needed during routine dental care, and most captive-born animals remained without decay for years; in our few wild-caught animals, decay did not proceed excessively, and tartar deposits were reduced, as was gum disease. I worry sometimes when I see how much sugary foods people seem to put into enrichment. Honey, raisins, and peanut butter should be treated with caution: not just because of tooth decay, but because of their high calorie content: animals need foods that meet all their dietary requirements, not just calories."
Rita said: "At our facility, we work closely with our vet staff to ensure that the animals receive their daily nutritional requirements, and that any 'treat' we give them does not interfere with those health/nutritional needs. We do try to limit excess fats/sugars (we go low-fat or sugar-free when possible), and we have quantity guidelines based on age, weight, and species for both produce and non-produce treats. Because our animals do not receive the fatty, sugary treats daily, our vets are satisfied that health (and dental care!) is not being compromised. 'Treats' can also be used in conjunction with health management. E.g., protein-deficient animals might receive higher-protein produce and treats. Our vet staff quite often requests special treats tailored to individual animals' needs." And Brooke said: We use Flintstones vitamins for monkeys with various mineral deficiencies. These contain a lot of sugar but are recommended by our vet."
Rita suggested low fat and sugar treats: * Cut up fresh produce and freeze it for a different texture. * Make plain ice cubes or ice cubes with sugar-free flavorings. Also, add cut produce to the ice cubes. * Increase the variety of produce you try. "We use everything from eggplant to mushrooms to bok choy to pumpkins." And Cobie added: "Other occasional treats were scattered breakfast cereal (without added sugar) in sawdust - even plain oatmeal flakes are great! For large numbers of primates, a cheap alternative is a horse mix (not the molasses-added kind!) made up of barley, corn, oats, and seeds; or a mixture of nuts. Also, try small whole pumpkins and see how they treat them, or whole hardboiled eggs in the shell!" And Brooke: "For those who are skeptical about sugar, it is possible to give slightly sweet treats. For instance, for day-to-day enrichment I mix honey or Pedialyte with a lot of water in a spray bottle and spray parts of the cages or their hands. Our rhesus monkeys spend much time smelling and licking, without ingesting much sugar."
Brooke added: "I find nothing wrong with giving sugar or salt in moderation. Our rhesus colony loves the occasional sweet treat, and our vet has assured us that this is completely acceptable. I even once worked at a sanctuary where the only primate (a rhesus), was continually fed restaurant leftovers (omelets, burritos, etc!), and while I don't agree with that sort of diet, he is still alive and well today, if a couple pounds heavier than he should be. Here, we give an assortment of treats varying from different fruits and vegetables, various monkey-specific manufactured treats (such as Primatreats®), and the occasional bit of honey, peanut butter, molasses, or marshmallows. I would never want to deprive them of this, because of the sheer enjoyment they appear to get out of it."
Now Hope wrote: "The main reason we have tried to limit sweets and salts is that these 'treat tubes' are being sent to several sanctuaries, and it is not our intention to disrupt or change the diets of the primates. Personally, I am in favor of a diet of fresh fruits and veggies (with additional foods appropriate to the species) and not lots of sweets. A mango is sweet enough, at least in my view. We don't include peanut butter, honey, etc., for all the reasons listed above -- also we're mailing (albeit Priority Mail), so don't want to include things that will spoil."
Cobie: "Our animals used to get tubes with their routine hard foods such as corn kernels (why pop them?) and sunflower seeds, or containers such as plastic bottles with their daily rations of hard foods made up of pellets, kernels, seeds, and cat biscuits. After the bottles were empty, they provided lots of fun in their destruction; the animals never tired of them even when given daily."
Hope asked about single-serving plastic water bottles. "The reason we haven't used them is that I have some concerns about ingestion. Those bottles break easily and I worry about these guys swallowing some of the plastic and getting into real trouble while they're trying to get at the goodies inside."
Cobie answered: "I've used plastic bottles (2-liter milk, which are the opaque plastic kind, and 2-liter fruit juice bottles, 'PET', that is, clear plastic) for a long time with pigtails and cynos. They like the PET more, I think, maybe because they can see better what's in them, or because they make more noise when destroyed. It is hard for even these strong guys to tear small pieces off them. Bottles usually ended up reduced from three to two dimensions! And they did not chew bits of plastic off or put pieces in their pouches, as far as I could see; anyway, there was always plenty of real stuff to ingest! Small (200- or 500-cc) bottles may be thinner, though; these might be a problem because they tear more easily."
And Sue wrote: "At our zoo we have a volunteer enrichment group that provides items for our chimps. Until recently there were five adults. We used plastic bottles and froze diluted juice in them or froze water with fruit in them. When a baby was born, the vet had us take these off our list of approved items. They had never been a problem with the adults, but there is concern about the baby ingesting plastic. The adults systematically bit and tore the plastic bottle off of the frozen goodie inside and ate the latter like a Popsicle. Even when we were allowed to use them, we found that the water bottles tended to shatter and were instructed to only use soda bottles, as they are thicker plastic."
Katie suggested trying nuts such as almonds or pistachios. "We give them whole to macaques, and shelled and chopped (or whole peanuts) to the New World monkeys - a little can go a long way. My co-worker, Paula Dvorchak, discovered a bird catalog called Hornbeck's [888-CAGEBIR(D)] that sells nuts and dried fruits in bulk for parrots. We use that in forage mix; it's much cheaper than we could buy in the store."
Hope: "We received a donation of walnuts the other day. Does anyone have any feedback on them? I've never heard of anyone feeding walnuts, and wondered if there was a reason why that I haven't heard."
Cobie has given whole walnuts on occasion: "Many animals played with them, and the bigger ones could crack them open and extract the flesh. One wild caught female would take them up and drop them on the concrete floor, then go inspect them to see if they cracked. No idea where she learned that trick!"
Brooke said: "I also give various interesting fruits and vegetables such as coconuts and corn on the cob (both provide hours of activity)." But Katie questioned corn on the cob, because "the veterinarians here all were very concerned that the monkeys might ingest the cob and that may result in blockages. Also, do you give them whole ears with the fiber still on or do you shuck them first?"
Jen, Cobie, and Brooke all agreed that corn on the cob (raw, whole, uncooked - no need to shuck!) is a great form of enrichment for macaques. Jen refers us to
<www.brown.edu/Research/Primate/lpn31-1.html#three>.
Brooke says some rhesus do eat the cob, but seem to chew it into small enough pieces. "Many do eat the outer husks. Our vet has said that they probably can't digest this, but it will just pass through (like celery). Many monkeys here only eat that and leave the corn!" Cobie gave large cobs, thinking small ones might make the possibility of the animals eating the cob, or biting chunks off it, more of a risk.

Tesis: Aporte Nutricional de Frutos de Ficus perforata (Pulpa, Semillas y Materia Animal) Consumidos por Monos Aulladores (Alouatta palliata mexicana), defendida por Tania Roswhita Urquiza Haas para obtener el título de Bióloga, Facultad de Ciencias UNAM, México, D.F.
Las semillas representaron un gran porcentaje del fruto completo (45%) por lo que los estudios que utilizan el fruto completo sobrestiman las concentraciones disponibles de todos los nutrientes, excepto fibra neutrodetergente, y el impacto es mayor para los lípidos. La materia animal aporta el 0.43% de proteína cruda y el 0.29% de extracto etéreo, esto representa el 11.13% y el 9.04% respectivamente de la fracción disponible (pulpa y materia animal). Se observaron diferencias significativas en el consumo entre las distintas clases sexo-edad (p<0.04), presentándose el mayor consumo de frutos por parte de las hembras adultas. Asimismo existen diferencias en el consumo por períodos del día (p<0.001), el mayor consumo se reporta por la tarde. La importancia del fruto de Ficus perforata para los monos aulladores puede deberse principalmente a los contenidos de calcio y agua.
Fossil Photographs
Anne-Marie Pecha, an editor for the World Book Encyclopedia's annual Science Year Supplement, wrote to Primate-Science on April 3: "I am writing in hope that you can help me find sources for any photographs of fossils of primates from the Paleocene and/or Eocene. We're putting together a feature-length article on early primates and have been having a rough time figuring out where to get photos of fossils of Paleocene Archontans (particularly Plesiadapiforms) and of Eocene primates. It seems that most scholarly journals publish drawings, which are useful in illustrating specific features of fossils to expert academics, but not useful in illustrating simply 'How scientists study fossil primates,' as we want to do. We already have photos of Purgatorius teeth and of Eosimias ankle bones, and are in the process of contacting researcher Christopher Beard's office about some photos we found on the Web. However, if you know of any museums or universities that might have photos of fossils on file, the information would be greatly appreciated. An entire skeletal reconstruction would be a gold mine. Thank you for your time and attention. Sincerely, Anne-Marie Pecha, Staff Editor Annuals and Online Products, World Book Publications, 233 N.

Primate Louse Samples
David L. Reed, an NSF Postdoctoral Fellow at the University of Utah, wrote to Primate Science: "We are in need of louse samples from primates. With the help of several colleagues, I am building a phylogeny based on DNA sequences for the sucking lice of primates. If you regularly come in contact with primates that have lice, we would appreciate your help in collecting them.
"In short, we are building this phylogeny to better understand the evolution of primate-associated lice. This, in turn, will help us to better understand the three taxa of sucking lice associated with humans. Human body lice carry several deadly diseases that could also be carried by human head lice, which are reaching epidemic proportions in school children. Our research efforts are addressing this issue. For more information about our research, see "If you can collect lice for us, they are best preserved in 95% ethanol (ethyl alcohol) until they can be frozen in ultra-cold freezers in our lab. I can provide vials of ethanol if you need them and we will certainly pay for shipping. We also need as much information about the primate host as you can provide. We need to know if the animal was wild-caught or captive born. If wild-caught, any collecting information that you have (location, date, collector, etc.) would be most beneficial. If the animal regularly comes in contact with other primate species, that would be important to know too (lice can switch hosts to some degree). Thanks for any help you can offer and don't hesitate to e-mail me if you have questions." - David L.

Becoming Human
The Institute of Human Origins has launched an on-line site for paleoanthropology, Becoming Human <www.becominghuman.org>. The centerpiece of the site is an interactive documentary experience that combines a 30-minute cinematic-style documentary with dozens of interactive exhibits. The documentary, guided by Dr. Donald Johanson, will take the viewer across the world and through four million years of history in search of how we became human.
Along the way, viewers will have the opportunity to "dig deeper" into the topics covered in the documentary, such as exploring a virtual archeological dig in Ethiopia, learning how researchers and artists reconstruct our ancient ancestors, listening in as leading scientists debate major issues in human evolution, and examining "virtual fossils" of many key members of our family tree.
Among the various levels of the Becoming Human site, visitors will be able to research the latest news in paleoanthropology and read expert essays in answer to viewer-submitted questions in the "News and Views" section. "Resources" will provide links to a growing collection of related Web sites, an extensive bibliography of books and articles, and a thorough glossary. The "Learning Center" will offer educational activities and lesson plans exploring major concepts in human evolution. For more information, visit <www.becominghuman.org> or call 480-727-6580. The project has been made possible by a generous grant from the Alfred P. Sloan Foundation.
Malaria Information on the Web
Malaria Foundation International (MFI) has recently acquired an interactive teaching module, created and generously shared by Donald Roberts and Gregory Andre. This module provides not only general malaria information, but also information pertinent to malaria control by use of DDT. It is designed to be useful to people with a wide spectrum of backgrounds.
This module is animated and interactive. It addresses: * The malaria parasite and the mosquito that passes it to humans; * When and how the infected mosquito comes in contact with humans; and * DDT's effectiveness at malaria control (you may independently assess the probability that DDT will reduce malaria transmission based on three factors). The module may be viewed directly at <www.malaria.org/teachingmodules/ddt.html>.

The Department of Veterinary Sciences of the University of Texas M. D. Anderson Cancer Center in Bastrop, Texas, is continuing to host Primate Training and Enrichment Workshops (PTEW). Enrollment is limited to 30 participants. One is scheduled for July 18-21, 2001, and another for February 20-23, 2002. The four-day PTEW emphasizes two areas of concentrated study that are of interest to personnel caring for nonhuman primates in zoos and laboratories: * enriching the environment; and * training nonhuman primates. For both areas, they will focus on a problem-solving approach, addressing the issues and problems that have been identified in participants' pre-workshop questionnaires. In July, for the first time, there will be a scholarship available for a worthy participant. The scholarship is courtesy of Priority One Services, Inc. and is intended to honor the memory of a deceased employee and PTEW veteran, Rodger James. Parts of the PTEW are sponsored by Bio-Serv, Primate Products, LabDiet, LGL Animal Care Products, and Priority One Services, Inc.
In addition, an Introduction to Primate Enrichment and Training workshop and an Advanced Primate Enrichment and Training workshop will be conducted at the national meeting of AALAS in Baltimore, Maryland, on October 22 and 23, 2001.

In 1999 We asked you all to consider whether you could get along without the paper edition of the LPN, and whether you would make an annual contribution to our costs of printing and postage if you could read the e-mail or Web-based editions, but preferred the paper. Eventually, We got good results, with nearly three-quarters of our readers "saving a tree", about 13% opting to pay for the ability to read the LPN at the beach or in the bathtub, and about 16% telling us honestly that they could not use either electronic edition for their purposes.
And in that first year, We did receive donations from the 13%. A few of the donations were extremely generous, and We don't want those donors (you know who you are!) to feel that they have to keep on sending Us more money. However, We were hoping that We would not have to do the bookkeeping involved in sending the rest of you annual invoices, and making sure that you responded to them. It was all going to be on the honor system...But that isn't working. So, starting in the October issue, We will enclose invoices for all those who had paid once and only once. And cards to those who said they really, REALLY, needed paper copies, which they will have to return if they want to stay on the mailing list.

2000 Harry C. Rowsell Award
The eighth annual Rowsell Award was given to Joe R. Held, DVM, at a reception held at the SCAW/UTHSC conference in San Antonio, Texas, in December.
Dr. Held was born in Los Angeles, California, and received his undergraduate education at Pasadena City College and the University of California at Davis. He earned his Doctorate in Veterinary Medicine at U.C. Davis in 1955. Immediately upon graduation he was commissioned as an officer in the U.S. Public Health Service, and was assigned to the Communicable Disease Center as an Epidemic Intelligence Service (EIS) Officer. Following EIS assignments to the states of Florida and Minnesota, he returned to his native Pasadena to the private practice of veterinary medicine. Subsequently his interest in the study and control of zoonotic diseases led him back to more graduate studies at Tulane University, in New Orleans, where he was awarded a Master of Public Health degree in 1959. He then returned to active duty in the Public Health Service.
For the next several years he held a variety of positions. In 1962 he was assigned to the National Institutes of Health, first as an administrator responsible for managing grants that established the Regional Primate Research Centers, then as a research parasitologist in the National Institute of Allergy and Infectious Diseases.
In 1969 he was reassigned to the NIH in Bethesda, Maryland, to serve as Chief of the Veterinary Resources Branch. In 1972, he became Director of the NIH Division of Research Services. In 1975 he was also designated as the PHS Chief Veterinary Officer, and was elevated to the rank of Assistant Surgeon General. He retired in 1996, and remains in touch with activities of the Public Health Service, and other entities dealing with subjects that have been of special interest to him.
Gorillas' Friend Wins Goldman Environmental Prize
Eugene Rutagarama of Rwanda, a biologist working for the International Gorilla Conservation Program (IGCP), has been honored for his work to save mountain gorillas during and after the 1994 genocide in Rwanda. Mr. Rutagarama risked his life to protect the animals and support those caring for them. He is one of this year's recipients of the Goldman Environmental Prize, which the organizers say is "given annually to environmental heroes" representing the different continents. Each recipient received $125,000 at a ceremony in San Francisco on 23 April. Mr. Rutagarama says he will use his prize to help national park staff and people living around two parks in Rwanda, Nyungwe Forest and the Volcano park in the Virunga mountains.
"Virunga straddles three countries, Rwanda, Uganda and the Democratic Republic of Congo (DRC)," Rutagarama said. "As the IGCP's program manager I'm responsible for staff in all three. And those in the DRC haven't been paid for the last six years."
He has repeatedly risked his life by traveling in rebel-held territory in the DRC to deliver funds and equipment to park rangers there. He says: "I was lucky not to be ambushed in the forest. Sometimes my staff would warn me to stay out of harm's way.
"It is the militias that are still the threat to the gorillas - they've killed some of them to deter tourists. But the gorilla population has begun increasing because of the courage of the field staff and the support of our partners." - By BBC News Online's environment correspondent Alex Kirby, posted to Alloprimate
Nominations for the 2001 Harry C. Rowsell Award will be accepted by the SCAW office until September 28, 2001.

Exploratory/Developmental Research Grants
The National Institute of Dental and Craniofacial Research (NIDCR) encourages applications for one-time grants to support innovative, high risk/high impact research requiring preliminary testing or development; exploration of the use of approaches and concepts new to a particular substantive area; research and development of new technologies, techniques or methods; or initial research and development of data upon which significant future research may be built. Applications will be considered as high impact if they demonstrate the potential for ground-breaking, precedent-setting significance, and high risk because they either lack sufficient preliminary data to ensure their feasibility, or involve using a new model system or technique. While this program announcement is intended to encourage innovation and high impact research, and while minimal preliminary data are expected to be described in the application, applications should clearly indicate that the proposed research and/or development is scientifically sound, that the qualifications of the investigators are appropriate, and that resources available to the investigators are adequate.
The research and/or development can be relevant to any of the branches, offices and programs of the NIDCR Division of Extramural Research (DER). The branches, offices and programs comprising the Division of Extramural Research at NIDCR are described in more detail at <www.nidcr.nih.gov/research/extramural/index.htm>.
In brief, the DER at the NIDCR provides support for: * basic and clinical research on the processes that affect normal and abnormal development of craniofacial structures; * basic studies on the ecological, molecular, biological and physiological factors contributing to microbial virulence, colonization and transmission; * genetic determinants of host susceptibility to infection; * oral manifestations of HIV infection and AIDS; * basic and applied research related to head and neck cancers; * basic and clinical studies on neurobiology, pathogenesis, diagnosis, treatment or prevention of pain; * autoimmunity; * biomimetics, tissue engineering, instrumentation development and refinement (e.g., saliva based diagnostic technologies), and development of methods to improve biomaterials for the repair of orofacial structures; and * clinical, behavioral and health promotion studies related to craniofacial, oral and dental health.

Bioinformatics and Applied Genomics Program Grants
The Special Programme for Research and Training in Tropical Diseases (TDR, a program of the World Health Organization) announces program grants to develop training centers/networks for research and training in bioinformatics and applied genomics, for which universities, research institutions and research organizations in Africa, Asia, and Latin America are invited to apply. The centers will focus on infectious and parasitic diseases, and will be developed to support and train scientists from the three regions. The ultimate goal is to establish sustainable research and training facilities by promoting utilization of genomics in developing countries that have endemic diseases.
The sum of US$45,000 will be awarded as initial support for improvements in computer, Internet, and local-area network infrastructure in the centers. The grant will also be used to cover the costs of travel and accommodation for students, staff, and at least three facilitators from outside the region to training workshops and courses. Support may be renewed annually subject to satisfactory evaluation.
All applications must be submitted via the Web. E-mail or paper applications will not be accepted, as access to the Web by the Principal Investigator is a major selection criterion. For details, instructions for applicants, and online application, please visit the TDR website: <www.who.int/tdr/grants/grants/bioinformatics.htm>.
Exploratory Research: Feasibility Pilot Studies
The National Institute on Deafness and Other Communication Disorders (NIDCD) invites applications for exploratory, initial feasibility pilot studies focused on hearing, balance, smell, taste, voice, speech, and language - the scientific mission areas of the NIDCD. Exploratory research involves initial feasibility pilot studies in which the technological, methodological, or theoretical approach to a problem lacks sufficient preliminary/baseline data and a body of peer-reviewed publications, but whose successful outcome would make a significant contribution to a scientific area or field. It is anticipated that most applications will be submitted by investigators with ongoing research programs who wish to change the focus of their current research effort or move into a new area of research within the communication sciences, but need additional funds to complete initial pilot studies. These grants are not intended for the advanced postdoctoral fellow starting to plan an independent research career or for the new investigator at the early stages of independence. Up to two years of support and up to $50,000 in direct costs per year will be provided. Areas of science with sufficient existing preliminary data to support the submission of a regular research grant application do not qualify under this program announcement.

Western Lowland Gorilla Born at Brookfield Zoo
The much-anticipated birth of a western lowland gorilla at Brookfield Zoo occurred early April 4. Baraka, 10, gave birth to a 4- to 5-pound infant around 3 a.m. The infant is named Nadaya, which means "first" in a Nigerian dialect. This birth is very significant for the western lowland gorilla population in zoos, because the father, Ramar, is wild-born and has not previously sired offspring. Ramar, a 33-year-old silverback, is on loan from North Carolina Zoological Park, following a recommendation from the American Zoo and Aquarium Association's Western Lowland Gorilla Species Survival Plan. Ramar arrived at Brookfield Zoo in 1998. At Brookfield, Ramar is the only male among a stable social group of several experienced females, most of whom have successfully produced offspring.
With the birth of this infant, there now are four generations of the same gorilla family at Brookfield. Two of the zoo's other gorillas are related to the infant - Babs, 26, is its grandmother and Alpha, 40, is the great-grandmother. Other members of the zoo's gorilla troop include Beta, 40; Binti Jua, 13; Koola, 6; and Bana, 6.
The newborn is Baraka's first offspring. Although she has witnessed the birth and rearing of other gorillas in the troop, the zoo's animal collection staff wanted to ensure that she was as prepared as possible for motherhood. As soon as the pregnancy was confirmed last September, primate keepers began maternal training sessions with the first-time mom. Using positive reinforcement, keepers have trained Baraka to perform several useful behaviors.
The western lowland gorilla is endangered due to habitat destruction, primarily from illegal and legal logging; the effects of war and refugees in ape habitats; the illegal pet trade; and poaching of apes for bushmeat. There are approximately 110,000 western lowland gorillas in their native land of West Africa and nearly 350 reside in North American zoos. Baraka, her new baby, and the rest of the gorilla troop can be seen in Brookfield Zoo's Tropic World/Africa exhibit.
For more information, see <www.brookfieldzoo.org> or contact Sondra Katzen, the Zoo's Media Relations Manager [708-485-0263; e-mail: sokatzen@brookfieldzoo.org]. - from Environmental News Network, April 11, 2001

Golden Lion Tamarin Born in Brazil
Environmentalists in Brazil are celebrating the birth of the 1,000th golden lion tamarin (Leontopithecus chrysopygus) in the wild, a milestone in the fight to preserve the rain forest species. The baby, weighing about 2.5 ounces and measuring 4 inches long, was born in March. Though scientists track the tamarins closely with radio transmitters, the milestone is based on an estimate of the population, said Denise Rambaldi, director of the Golden Lion Tamarin Association, a WWF-affiliated group. Biologists say that the tamarins declined in number during the 1950s and 1960s because of destruction of their habitat, the South American rain forest. They were also captured and sold as pets.
When efforts to save the monkey began 30 years ago, there were only 200 tamarins living in isolated patches of rain forest across Rio de Janeiro state and parts of neighboring Espirito Santo state. Today there are five times that many, concentrated in an area around Poco das Antas Biological Reserve, 80 miles northeast of Rio. Since then the tamarin has had its tufted face printed on everything from T-shirts to postage stamps as a symbol of Brazil's endangered wildlife.
But Rambaldi says the battle is only half won. To ensure genetic diversity, the tamarin population must double over the next 25 years or face extinction from inbreeding. Scientists have been trying to diversify the gene pool. Over the past 17 years, 174 tamarins from foreign zoos have been successfully reintroduced. But conservationists face another problem - where to put the multiplying monkeys. Rambaldi says to sustain a population of 2,000 tamarins would require some 62,000 acres of forest - about twice as much as they now have.
"The next 25 years are going to be more difficult ... Now we have to find more forest for them to inhabit," said Garo Batmanian, director general of the World Wildlife Fund in Brazil. Batmanian says the next phase of the program is to convince local farmers and landowners that it is in their interest to leave some of the remaining forest standing. These efforts received a boost Wednesday, when Brazil's Minister of Environment, Jose Sarney Filho, announced the government would begin studies to declare the area around the reserve an "Environmental Protection Zone." Batmanian said the zoning change gives conservationists more power in negotiating with farmers. - By Michael Astor, Associated Press Writer
...And at Palm Beach Zoo
Jasmine, the Palm Beach Zoo's female golden lion tamarin, gave birth to twins April 3. The birth of the twins is the first for the species at the zoo, although tamarins have been exhibited there for more than 15 years. Jasmine, two years old, came from the Denver Zoo 18 months ago. Her mate is 16-year-old Beau, who came from the National Zoo in Washington, D.C., in 1991. - by Tim O'Meilia for the Palm Beach Post
Brazil Yellow Fever Outbreak Kills Twelve
An outbreak of yellow fever has killed at least 12 people in recent weeks in a rural area of Brazil's eastern state of Minas Gerais, and may have infected another 20, a health official said on March 12. The tropical disease, endemic to South America, causes shakes, fever, nausea and vomiting and can lead to liver and kidney damage, causing hemorrhaging and death.
The new cases of yellow fever are the first in Brazil in the eight months since the government led an aggressive vaccination campaign, the government's National Health Foundation, or Funasa, said. The disease, transmitted to humans by mosquitoes, killed 39 people in Brazil last year and 18 in 1999. Monkeys also carry the virus. Funasa said the recent outbreak was isolated, blaming it on the migration of primates and an increase in tourism in the region by people who had not been vaccinated.
Yellow fever thrives in Brazil's Amazon rain forest and is also present in Colombia, Ecuador, and Venezuela, while Peru and Bolivia have registered the most violent outbreaks in the past decade. - By Katherine Baldwin for Reuters, posted to Alloprimate
Monkey Mortality, Yellow Fever?
More than 20 howler monkeys [Alouatta sp.] were found dead this April in forests in the municipalities of Santo Antonio das Missoes and Garruchos, in the Missoes region of Rio Grande do Sul [RGS], Brazil. The cause is suspected to be either yellow fever or poison.
Specialists from [the virus laboratory of] the Evandro Chagas Institute at Belem, Para, the RGS state health secretariat, and Ibama [forestry department] are investigating. Yellow fever vaccination has been carried out among residents of the area near the Rio Uruguai and of the forests inhabited by howler monkeys.
Deaths in howler monkeys in South America have historically indicated the emergence of a new sylvan yellow fever outbreak, transmitted between monkeys by Haemagogus mosquitoes. Humans become tangentially infected when working in or traveling through forests where a monkey epizootic is occurring. - from a ProMED announcement reposted to Alloprimate, May 22
New AAALAC European Assistant Director
The Association for Assessment and Accreditation of Laboratory Animal Care International (AAALAC) has appointed Dr. Egil Berge of Lasne, Belgium, Assistant Director for European Activities. AAALAC works with the scientific community to promote the responsible treatment of research animals. This is done through a voluntary accreditation program under which organizations demonstrate exceptional levels of humane animal care and use. More than 630 educational, commercial and governmental, and nongovernmental institutions in 16 countries have earned AAALAC accreditation.
Dr. Berge will serve as AAALAC's principal spokesperson throughout Europe, providing valuable information on the role AAALAC accreditation has in ensuring animal well-being and high-quality science. Dr. Berge will play an important role for AAALAC through his involvement with the Federation of European Laboratory Animal Science Associations (FELASA), the European Society of Laboratory Animal Veterinarians, and the European College of Laboratory Animal Medicine.
Dr. Berge is a veterinarian who spent most of his career - 27 years - working as the department manager, and later associate director, for the In Vivo Control Laboratory of RIT/SmithKline Beecham Biologics in Rixensart, Belgium. He is currently president of the Belgian Council for Laboratory Animal Science, a position he has held since 1995. Dr. Berge also served as secretary of FELASA from 1996 through 2000, and currently serves as FELASA's vice president for relations with the Council of Europe and the European Union.

Farmers Moved to Make Room for Monkeys
More than 200 peasant farmers in Kenya's Tana River district are to be relocated from their ancestral land to create room for the red colubus and crested mangabey monkeys, the Kenya Wildlife Services (KWS) announced. In return, 247 of 330 families moved out of the 166-square kilometre Tana River Primate National Reserve will be given residential houses in a new settlement scheme.
Some of the peasants, who grow bananas and corn, are reluctant to move from the fertile land, however, and accuse the KWS of being more concerned with the plight of monkeys than of people. "We are against everything that has happened. We will never leave," said Seth Ablo, a 76-year-old man who has farmed on the land all his life. He represents about 100 families who are reluctant to move out of the reserve. KWS corporate communications manager Connie Nkatha-Maina said each family would get 15 acres of farmland with a title deed, a quarter acre land of a housing plot, a fully constructed house and access to clean water. The new resettlement scheme will also include an equipped primary school, police station and a dispensary.
In February this year, several dozen chanting women angrily charged at scientists working on the edge of the reserve. The women exposed their private parts as the highest form of insult.
There are about 2400 rare red colubus and crested mangabey monkeys in the reserve. KWS is currently implementing a US$6.2 million World Bank-funded project to protect the primate reserve. The primate reserve is the last vestige of riverine forest system in Kenya. - By Stephen Mbogo, for the African Eye News Service (Nelspruit), April 17, 2001, posted to primfocus
Lackner to Tulane RPRC
Dr. Andrew Lackner, Associate Professor of Pathology at Harvard Medical School and Chairman of the Division of Comparative Pathology at the New England Regional Primate Research Center, has been appointed the new Director of Tulane's Regional Primate Research Center. He will replace Dr. Peter Gerone, who has headed the center since 1971.
San Diego Zoo Plans Major New Exhibit
Preparations are under way at the San Diego Zoo to demolish the "monkey yard" to make room for an exhibit that will house several different species in a more natural environment. The new space, called Heart of the Zoo, is a continuation of the zoo's move toward transforming the park into a more ecologically correct exhibition center, the San Diego Union-Tribune reported. The current monkey yard is a concrete block structure with about 36 cell-like enclosures, dating back to the days when designers were simply concerned with sanitation, the newspaper reported. The design made it easy to hose down the cages quickly and efficiently.
"Today, the mental well-being and health needs of the animals are the priority, and people want to see natural looking enclosures, not monkeys hanging off a cement tree," Zoo Curator of Mammals Karen Killmar told the newspaper. The new exhibit will house not only primates, but other mammals as well, including the pygmy hippo, clouded leopard and a forest antelope called the duiker, along with reptiles and birds, the newspaper reported. Walkways leading up to the treetop canopy and down to the forest floor will allow people "to see the space from three levels," zoo architect Robyn Badger said. The Heart of the Zoo project will cost an estimated $25 million. - Posted to primfocus by Linda J. Howard, March 23, 2001
Infant Chimps from Coulston to Sanctuary
Two baby chimpanzees, 11-month-old Samuel and 8-month-old Champ, were released from the Coulston Foundation to Primarily Primates, Inc., of San Antonio, Texas. Samuel has been diagnosed with congenital hypothyroidism, which has never before been documented in chimpanzees. If left untreated, congenital hypothyroidism causes deficiencies in motor skills, affects growth rate, and may cause some mental disability. Samuel will require physical therapy and thyroid replacement hormone treatment for the rest of his life. Champ, who is healthy, is Samuel's nursery mate and friend.
Primarily Primates, which cares for more than 800 animals from zoos, research, entertainment, and private homes, has 75 chimpanzees and many other nonhuman primates. - From a press release, April 23, 2001
B. J. McDuffee, Orang Gang Co-Founder
After the 1997 ASP meeting, your Editors visited the San Diego Zoo. At the orangutan exhibit, we met Betty Jo McDuffee, who told us anecdotes about the animals as we watched them. At our request, she wrote the article, "Clyde, the Parenting Orangutan," which we published in the LPN (1998, 37[1], 18-19). We were saddened to read, in issue 16 of the Orang Gang News, that B. J. had died on February 24, 2001, after surgery and illness.
The International Association for Medical Assistance to Travelers (IAMAT), a volunteer group, compiles an annual list of doctors around the world who meet the organization's criteria, who speak English or another second language, and who agree to charge a specific fee. The 2001 Directory lists the current schedule of fees as US$55 for an office visit, US$75 for a house (or hotel) call, and US$95 for night, Sunday, and holiday calls. These fees do not include consultants, laboratory procedures, hospitalization, or other expenses. The 72-page listing of doctors and centers includes 109 countries. IAMAT also publishes and provides to its members pamphlets on immunization and on malaria.

After reading the Editorial Note published in Laboratory Primate Newsletter (39[4], 15), and the comments in the next issue (40[1], 16), I would like to provide a statement to enrich the discussion about the "howling howlers". It is not my intention to state which must be the "right" English name, but I hope that by looking at the local names given to the "howlers" in their native countries we can add comprehension in order to select an English name for the members of the genus Alouatta.
In Latin America, the "howlers" are well known for some of their particular characteristics, like the reddish color of Alouatta seniculus. From Venezuela to Bolivia this monkey has the Spanish names of mono colorado, mono rojo, or mono vermejo, all meaning red monkey. However, in those countries they are mainly known and named after their particular roaring or howling behavior. Consequently, the most widespread Spanish names, not including those of indigenous roots (like araguato and saraguato), are aullador, berreador, and roncador. The latter three names have been used from Colonial times to the present and are nouns that only mean "howler".
Spanish appellations for "howlers" are mono aullador, mono berreador, and mono roncador, that when translated into English mean "howler monkey". The term "howling monkey" in a Spanish translation means a monkey that is howling. In this sense, it is possible to find sentences from the locals like: "Escuché un mono aullando (I heard a howling monkey)" which, depending on time of day, could be a howler or a night monkey (Aotus spp.). In contrast, the Spanish expression, "Escuché un aullador (I heard a howler)" refers only to a howler. Therefore, I think the use of the term "howler" might resolve the question. - Bernardo Urbani, Departamento de Biología de Organismos, Universidad Simón Bolívar, Apartado 47.028, Caracas 1041-A, Venezuela [e-mail: urbani@cantv.net]
The Public Health Service (PHS) Policy on Humane Care and Use of Laboratory Animals requires that Institutional Animal Care and Use Committees reviewing PHS-conducted or supported research projects determine that the methods of euthanasia used will be consistent with the recommendations of the American Veterinary Medical Association Panel on Euthanasia, unless a deviation is justified for scientific reasons in writing by the investigator. The PHS Policy is applicable to all PHS-conducted or supported activities (including research, research training, experimentation or biological testing or related purposes) involving live, vertebrate animals. In addition, USDA Animal Care Policy #3 issued January 14, 2000, and applicable to many PHS awardee institutions, also requires that methods of euthanasia be consistent with the most current Report of the AVMA Panel on Euthanasia unless a deviation is justified for scientific reasons.
The 2000 Report of the AVMA Panel on Euthanasia was published in the Journal of the American Veterinary Medical Association on March 1, 2001, 281[5] and is posted at: <www.avma.org/resources/euthanasia.pdf>. The Office of Laboratory Animal Welfare expects all PHS-Assured institutions to use the 2000 Panel Report after May 1, 2001. Previously approved projects undergoing continuing review in accordance with IV.C.5. of the PHS Policy, which requires a complete de novo review at least once every three years, must be reviewed in light of the 2000 Panel Report after May 1, 2001.

Los frutos de Ficus son un importante recurso para la comunidad frugívora de los bosques tropicales, sin embargo existe incertidumbre acerca de su importancia nutricional. En la mayoría de estudios, los análisis químicos se han hecho de frutos completos, a pesar de que las semillas no pueden ser aprovechadas en la digestión. Se especula también acerca del aporte nutricional de la materia animal alojada en el fruto, por tanto el presente estudio pretende contestar las siguientes preguntas: ¿Cuál es el aporte nutricional del material animal alojado en los frutos de Ficus perforata y que es ingerido incidentalmente por Alouatta palliata mexicana? ¿Qué aporte de nutrientes proporcionan las fracciones de los frutos de Ficus perforata a los monos aulladores? ¿Cuál es la importancia nutricional del fruto de Ficus perforata dentro de la dieta del mono aullador? Durante el período de fructificación de un árbol de Ficus perforata se estimó el consumo de frutos por parte de los monos aulladores y se realizaron análisis químicos para determinar el contenido de proteína cruda, extracto etéreo, cenizas, fibra (celulosa, hemicelulosa, lignina) del fruto completo y de las fracciones pulpa y semillas, asimismo se realizaron análisis para determinar la proteína cruda y extracto etéreo de la fracción materia animal.

. . ."Neurons in the lateral belt areas of rhesus monkey auditory cortex prefer complex sounds to pure tones, but functional specializations of these multiple maps in the superior temporal region have not been determined. We tested the specificity of neurons in the lateral belt with species-specific communication calls presented at different azimuth positions. We found that neurons in the anterior belt are more selective for the type of call, whereas neurons in the caudal belt consistently show the greatest spatial selectivity. These results suggest that cortical processing of auditory spatial and pattern information is performed in specialized streams rather than one homogeneously distributed system."
. . . The objective of this project was to better define the similarities and differences in gastrointestinal morphology present in lemur species. Measurements of the gastrointestinal tract of lemurs were obtained at necropsy from the captive population at Duke University Primate Center. Measurements of body length and weight, as well as gastrointestinal length, were recorded. Photographs and measurements were used to obtain illustrations. Preliminary results suggest differences in gastrointestinal morphology among lemur species that coincide with differences in diet. Distinct sacculations in either the cecum or the colon were present for H. griseus, L. catta, P. verreauxi, and P. tattersalli, but not for V. variegata. The Propithecus specimens possessed a much greater ratio of gastrointestinal length to body length than the other three species. A short, blunt cecum and a shortened and sacculated colon were unique characteristics of the H. griseus specimens. These differences correlate well with a dietary shift from consumption of large amounts of structural plant cell wall (Propithecus sp.) to consumption of variable or moderate amounts (H. griseus, L. catta, and V. variegata). They also suggest that captive groups would benefit from further diet refinement in captivity.
. . . Heterologous prime/boost regimens have the potential for raising high levels of immune responses. DNA priming followed by a recombinant modified vaccinia Ankara (rMVA) booster controlled a highly pathogenic immunodeficiency virus challenge in a rhesus macaque model. Both the DNA and rMVA components of the vaccine expressed multiple immunodeficiency virus proteins. Two DNA inoculations at 0 and 8 weeks and a single rMVA booster at 24 weeks effectively controlled an intrarectal challenge administered 7 months after the booster. These findings provide hope that a relatively simple multiprotein DNA/MVA vaccine can help to control the acquired immune deficiency syndrome epidemic.
. . . The purpose of the present study was to determine whether various behavioral and hormonal markers obtained in individually housed monkeys would be predictive of social rank following group housing. Body weight, serum cortisol and testosterone levels, and locomotor activity in an open-field apparatus were examined in 20 experimentally naive male cynomolgus monkeys while they were individually housed. It was hypothesized that eventual subordinate monkeys would have higher cortisol levels and increased locomotor activity scores. These monkeys were then placed in social groups of four (five pens of four monkeys), and social rank was determined based on outcomes of dyadic agonistic encounters. Body weight correlated significantly with eventual social rank. In general, the heavier the monkey the higher the social rank. Locomotor activity in an open-field apparatus following administration of a low dose of cocaine (0.01 mg/kg, i.v.), which has been shown to increase CNS dopamine, correlated with eventual social rank such that individually housed monkeys with high levels of locomotion were more likely to become subordinate. Serum cortisol and testosterone levels failed to correlate with eventual social rank. Hypothalamic-pituitary feedback sensitivity and adrenal responsiveness were examined by measuring cortisol levels after administration of dexamethasone and following ACTH challenge. Cortisol responses in these tests were not associated with eventual social rank. These results suggest that, in addition to body weight, the level of reactivity in a novel environment after administration of a low dose of cocaine is a potential trait marker for social rank. This trait is apparently not associated with hormone levels, but may involve other CNS mechanisms.
. . ."There is increasing evidence that areas of outstanding conservation importance may coincide with dense human settlement or impact. We tested the generality of these findings using 1ø-resolution data for sub-Saharan Africa. We find that human population density is positively correlated with species richness of birds, mammals, snakes, and amphibians. This association holds for widespread, narrowly endemic, and threatened species, and it appears it will persist in the face of foreseeable population growth. Our results contradict earlier expectations of low conflict based on the idea that species richness decreases and human impact increases with primary productivity. We find that across Africa, both variables instead exhibit unimodal relationships with productivity. Modifying priority-setting to take account of human density shows that, at this scale, conflicts between conservation and development are not easily avoided, because many densely inhabited grid cells contain species found nowhere else."
. . . Love of wild nature appears in many human cultures, and may even be a human instinct. In her essay, Jolly asks if future human species will share that love, as after the current mass extinction it may take at least five million years to recover our present level of biodiversity. The effort to save what we have, in particular our primate relatives the monkeys and great apes, crucially involves scientists in countries where wild primates live.
. . . Senile plaques (SPs) were found in the cerebral cortex of a 44-year-old western lowland gorilla (Gorilla gorilla gorilla). All the SPs were obtained as dense assemblies consisting of fibrous materials by silver impregnation, but were not detected by Congo red. More SPs were detected by immunostaining for amyloidâ protein (Aâ) and a half of Aâ-positive-SPs were also immunoreactive for apolipoprotein E. Moreover, all SPs were immunoreactive for Aâ 42 and Aâ 43, but not for Aâ 40. SPs also did not contain Aâ precursor protein-positive structures. These findings suggested that SPs in this case were diffuse plaques.
. . . A search through the archives clears early vaccines of starting the AIDS pandemic. Analysis of frozen samples of the suspect vaccine by using the polymerase chain reaction (PCR) to amplify any HIV-1-related nucleic acids or chimpanzee mitochondrial DNA that might be present, failed to detect either.
. . . The origin of human immunodeficiency virus type 1 (HIV-1) is controversial. It is shown that viruses obtained from the Democratic Republic of Congo in Africa have a quantitatively different phylogenetic tree structure from those sampled in other parts of the world. This indicates that the structure of HIV-1 phylogenies is the result of epidemiological processes acting within human populations alone, and is not due to multiple cross-species transmission initiated by oral polio vaccination.
. . . Here we use a molecular analysis to show that two CHAT type-1 polio vaccine stocks were prepared from macaque and not chimpanzee cells, and contain neither human nor simian immunodeficiency virus sequences. Our results do not support the hypothesis that these materials were responsible for the transmission of the AIDS virus to humans.
. . . Most interpretations of early hominin phylogeny recognize a single early to middle Pliocene ancestral lineage, best represented by Australopithecus afarensis, which gave rise to a radiation of taxa in the late Pliocene. Here we report on new fossils discovered west of Lake Turkana, Kenya, which differ markedly from those of contemporary A. afarensis, indicating that hominin taxonomic diversity extended back into the middle Pliocene. A 3.5 million-year-old cranium, showing a unique combination of derived facial and primitive neurocranial features, is assigned to a new genus of hominin. These findings point to an early diet-driven adaptive radiation, provide new insight on the association of hominin craniodental features, and have implications for our understanding of Plio-Pleistocene hominin phylogeny.
. . ."All African apes walk on their knuckles. There is no evidence for this behavior in the earliest hominids, however, which conflicts with molecular DNA evidence suggesting that chimpanzees are more closely related to humans than to gorillas. On the basis of a multivariate analysis of four traits of the proximal wrist joint, Richmond and Strait claim that African apes and early hominids do share a common knuckle-walking ancestor. I propose that these traits are not uniquely associated with knuckle-walking and question the basis of their conclusion. It is still possible that no human ancestor knuckle-walked and that this behavior evolved independently in different species."
. . . Trichromatic color vision, characterized by three retinal photopigments tuned to peak wavelengths of 430 nm, 535 nm and 562 nm, has evolved convergently in catarrhine primates and one genus of New World monkey, the howlers (genus Alouatta). This uniform capacity to discriminate red-green colors, which is not found in other mammals, has been proposed as advantageous for the long-range detection of either ripe fruits or young leaves (which frequently flush red in the tropics) against a background of mature foliage. Four trichromatic primate species in Kibale Forest, Uganda, eat leaves that are color discriminated only by red-greenness, a color axis correlated with high protein levels and low toughness. Despite their divergent digestive systems, these primates have no significant interspecific differences in leaf color selection. In contrast, eaten fruits were generally discriminated from mature leaves on both red-green and yellow-blue channels and also by their luminance, with a significant difference between chimpanzees and monkeys in fruit color choice. These results implicate leaf consumption, a critical food resource when fruit is scarce, as having unique value in maintaining trichromacy in catarrhines.
. . . A hallmark of mammalian brain evolution is the disproportionate increase in neocortical size as compared with subcortical structures. Because primary visual cortex (V1) is the most thoroughly understood cortical region, the visual system provides an excellent model in which to investigate the evolutionary expansion of neocortex. Here the numbers of neurons in the visual thalamus (lateral geniculate nucleus; LGN) and area V1 are compared across primate species. The number of V1 neurons increases as the 3/2 power of the number of LGN neurons. As a consequence of this scaling law, the human, e.g., uses four times as many V1 neurons per LGN neuron (356) to process visual information as does a tarsier (87). It is argued that the 3/2 power relationship is a natural consequence of the organization of V1, together with the requirement that spatial resolution in V1 should parallel the maximum resolution provided by the LGN. The additional observation that thalamus/neocortex follows the same evolutionary scaling law as LGN/V1 may suggest that neocortex generally conforms to the same organizational principle as V1.
. . . This work presents the results of a demographic analysis of 30 years of breeding records from the University of Washington's recently closed Primate Field Station at Medical Lake, Washington. Summaries of population growth, age-specific fertility and mortality rates, first-year survival, and seasonality of reproduction are presented, as well as an analysis of survival by decade. In addition, data on interbirth intervals in this population are presented. In general, pigtailed macaques represent a typical Old World monkey pattern of age-specific fertility and mortality, with a few minor exceptions. Pigtailed macaques seem to be most similar to rhesus and Barbary macaques, while Japanese and bonnet macaques differ somewhat in their demographics.
. . . Among the 19 species of Macaca that are found in southern and eastern Asia, as well as northwestern Africa, the Formosan macaque is one of the least known. A long-term field study to investigate the population dynamics and social behavior of 7-16 troops of free-ranging Formosan macaques at Mt. Longevity, Taiwan, has been conducted since July 1993. Between 1994 and 1997, a systematic census was conducted on a biweekly basis. Focal animal sampling and ad libitum sampling were used twice a week to record data on social behavior, including male replacement and fission processes. The maximum density was estimated as 26 individuals/km2 in October, 1997. The average troop size was 26.1 +/- 9.7 (n = 7) in January, 1995, and reached the highest level, 47.0 +/- 21.2 (n = 13), in August, 1997. Two cases of fission were observed. Births were recorded mainly between April and June (97%) with a peak in mid-April to mid-May. About 88% of alpha male changes occurred between October and February - the peak and end of the mating season, respectively.
. . . Owl monkeys are small monogamous primates ranging over a wide area extending from Panama to the Chaco region of northern Argentina. The Chaco, an alluvial plain covering over one million km2 of Argentina, Bolivia, Brazil, and Paraguay, consists of a mosaic of grasslands, savannas, xeric thorn forests, and gallery forests. The region shows significant seasonal variation in climate, rainfall, and food availability. The goal of this study was to determine the density, size, and structure of a population of Aotus azarai in the seasonal gallery forests of the eastern Argentinean Chaco. Reported population density, group size, and composition are based on data collected from 11 groups contacted on approximately 900 occasions, and observed for over 2,000 hours during a three-year period. Group and individual densities were 16 groups/km2 and 64 individuals/km2, respectively. Approximately half of the groups (n = 5) were small groups that had three individuals most of the time and never more than four, whereas the remaining groups were large groups composed of four or five, and sometimes even six or seven individuals. This is the first study of A. azarai based on monitoring of a relatively large number of distinct groups. The data suggest that owl monkeys in the seasonal subtropical forests of Formosa live at a density as high as those reported for owl monkey populations observed in tropical forests. The data also show that the social groups in the owl monkey population are comparable in size and composition to those of populations in the tropics.
. . . Penile vibrostimulation (PVS), a noninvasive repeatable method, has been shown in the squirrel monkey to yield semen of higher quality than rectal probe electro-ejaculation (RPE). The present study aimed at establishing the conditions for PVS to collect ejaculates from marmoset monkeys. Ten adult males were trained on the appropriate handling before each was subject to six to 12 PVS tests. Ejaculation was stimulated using a FertiCare® personal vibrator fitted with a 2 cm x 0.5 cm i.d. glass tube. The stimulus was repeatedly applied over a frequency of 75-95 Hz and amplitude of 1-2 mm for up to 20 min. Ejaculates were analyzed for volume, total sperm number, sperm concentration, and proportion of living and motile sperm. Ejaculates were obtained in 31 of 88 PVS tests; 87.1% of the ejaculations occurred at 80-85 Hz frequency and 1-1.5 mm amplitude. In 18 tests ejaculates were produced within 49.7 seconds. Ejaculates were characterized by (mean values): volume 31.9l, total sperm number 34.2 x 106/ejaculate, concentration 1,154.2 x 106 sperm/ml, live sperm 74.6%, motile sperm 59.6%. Total number and concentration of spermatozoa were significantly enhanced in singly-living males. PVS yielded three to four times more spermatozoa than comparable previously published values for RPE. Enhancing the success rate by preselecting males for responsiveness may render PVS the sperm collection method of choice in marmoset monkeys.
. . . To investigate primate color objectively, it is critical to employ tools that yield reliable measures of color samples. Primatologists have traditionally depended on color assessment methods that lack accuracy, precision, and replicability. In this work, the red, green, and blue (RGB) method, a technique combining digital video cameras and Adobe PhotoShop®, is introduced as a means to assess and graphically represent primate color objectively. The reliability and validity of the RGB method is demonstrated, and color measures obtained from the scrota of adult vervet monkeys are reported in order to outline the steps for assessing color samples.
. . ."The females of many Old World primate species produce prominent and conspicuous swellings of the perineal skin around the time of ovulation. These sexual swellings have been proposed to increase competition among males for females or to increase the likelihood of a female getting fertilized, by signaling either a female's general reproductive status, or the timing of her ovulation. We show that sexual swellings in wild baboons reliably advertise a female's reproductive value over her lifetime, in accordance with a theoretical model of honest signaling. Females with larger swellings attained sexual maturity earlier, produced both more offspring and more surviving offspring per year than females with smaller swellings, and had a higher overall proportion of their offspring survive. Male baboons use the size of the sexual swelling to determine their mating effort, fighting more aggressively to consort females with larger swellings, and spending more time grooming these females. Our results document an unusual case of a sexually selected ornament in females, and show how males, by mating selectively on the basis of the size of the sexual swelling, increase their probability of mating with females more likely to produce surviving offspring."
. . . In many primate species, male infanticide is assumed to pose a serious risk for infants, and therefore female counter-strategies are expected. These counter-strategies may include changes in the females' reproductive behavior and physiology, e.g., mating with multiple males and prolonged receptivity. Since the risk of infanticide is particularly high when a new male enters the group or when a male rises in rank, the changes in female reproductive conditions, e.g., post-partum amenorrhea and interbirth intervals, were studied following group take-overs by new males in a captive group of hamadryas baboons (Papio h. hamadryas). Following take-overs, five out of six lactating females immediately developed sexual swellings, thus shortening their post-partum amenorrhea. However, none of these females conceived during the first cycles after the take-over, their reproduction was not accelerated, and four out of five dependent infants survived. Thus, interbirth intervals did not decrease compared to times with no group take-overs. We therefore suggest that these situation-dependent swellings are used by female hamadryas baboons as a counter-strategy to reduce the risk of infanticide, which exists in this species after male take-overs. By offering new males mating opportunities without allowing them to reproduce, females may increase their infants' probability of survival and at the same time avoid the costs of being pregnant and lactating simultaneously.
. . . The patas monkeys in Kala Maloue, Cameroon, have their birth season in the mid-dry season, whereas closely related, sympatric tantalus monkeys have their birth season in the wet season. To evaluate the optimality of a species-specific birth season, the daily intake of available energy and gross protein, and energy expenditure were estimated for one individual of each sex of each species between respective birth and mating seasons. The monkeys obtained a larger amount of available energy and gross protein in the birth season than in the mating season. No significant seasonal differences in energy expenditure between the birth and mating season were found. Thus, the birth season appears to be timed to the season when the monkeys can obtain more surplus energy and protein. Interspecific differences in the optimality of birth season were attributed to widely exploitative foraging, supported by the patas' high locomotive ability, which may enable them to obtain more energy from seeds of Acacia seyal and gums of A. sieberiana, and more protein from grasshoppers and seeds of A. seyal in the mid-dry season than the tantalus monkeys. A review of preceding studies suggests that the availability of seeds of Acacia fruiting during the dry season may exert the dominant influence on timing of birth not only in patas but also in savanna monkeys (Cercopithecus aethiops), which include the tantalus monkeys.
. . . Follicle stimulating hormone (FSH) has fundamental importance in reproductive function, but its cyclic pattern has not previously been described in the squirrel monkey, due primarily to the lack of a suitable assay. An homologous radioimmunoassay (RIA) based on recombinant cynomolgus FSH measured changes in serum FSH relative to patterns of bioactive luteinizing hormone (LH), estradiol, and progesterone during the estrous cycle. FSH was observed to have a sharp peak during the late follicular phase coincident with the LH surge and then rose again during the luteal phase. Estradiol was low except for the midcycle rise, suggesting an inhibitory relationship. The rat granulosa cell in vitro FSH bioassay confirmed high levels of this hormone. Measurement of FSH in the squirrel monkey has found a pattern different from Old World primates in the luteal phase, which may provide insight into the reproductive mechanisms of this species.
