Although involuntary physical restraint of a primate causes stress if the animal is not fully habituated, it is often used to achieve experimental objectives, and sometimes to protect personnel. Considerations for the physical restraint of laboratory animals have been described by the Institute for Laboratory Animal Research (2003), and methods of restraint for the larger-bodied nonhuman primates housed in laboratories by Reinhardt et al. (1995). Considerations for restraint of the smaller bodied primates, such as marmosets (Callithrix spp.), have received less attention. Larger primates have been successfully trained, using positive reinforcement techniques, to cooperate with injections and blood sampling, and this is known to minimize the associated adverse effects (Reinhardt, 2003). However, because of their small size, and the precision needed, marmosets can probably not be trained using positive reinforcement techniques to present a limb for blood sampling and for injections. Therefore, methods of restraint are needed.
Marmosets have been used extensively for many years as experimental animals and yet few laboratories have used restraint devices for taking samples from them, or for giving them injections. Capture and manual restraint of marmosets is likely to cause them considerable stress (Poole et al, 1999). Sometimes two or three technicians are involved, one to restrain and the other(s) to carry out the procedure (Hearn, 1977; Buchanan-Smith, personal observation); some laboratories may even use unnecessary sedation (Morris, personal observation). Furthermore, the marmoset is often restrained on his or her back in the horizontal position (Buchanan-Smith, personal observation), which is likely to make the marmoset feel vulnerable, as this is not a normal postural position and prevents the marmoset from looking around the room. Our device holds the marmoset in a near vertical position, which is more natural, allowing the marmoset to see events and use her arms to adjust the position of her upper torso within the restraint tube.
Two papers originating from this laboratory have previously described a restraint device for marmosets (Hearn, 1977; O’Byrne & Morris, 1988). In this paper we shall describe an improved method for restraining the marmoset that appears to minimize the adverse effects of restraint and is therefore considered a Refinement (cf. Russell and Burch’s  “Three Rs of Replacement, Reduction and Refinement”). The device can be used for a number of techniques, is reliable and easy to maintain, and most animals can be habituated to its use. The device has been used in our laboratory for many years, and techniques using this device can be carried out by one person alone.
Marmosets who are habituated to the device do not alarm vocalize, nor do they struggle. They appear relaxed in posture and inquisitive, and will take a food reward at the end. Highly stressed marmosets behave quite differently. Ideally however, quantitative data on both behavior and physiology are required to state definitely that this method of restraint is less stressful than the alternatives.
Figure 1: The marmoset in the restraint device. Her arms and head protrude from the top, the Velcro strap is attached around her abdomen, and the care worker is attaching a Velcro strap to one leg. Note that the tail is also restrained with the leg from which the sample is not taken.
This device is designed for use in short-term restraint – on average 1-3 minutes, though occasionally this may be extended to up to 5 minutes. Figure 2 illustrates the three main parts of the device; Figures 3 and 4 the design and parts for the board supporting the marmoset. The device is constructed of inexpensive materials which can be obtained readily, and can be cleaned or sterilized easily.
Our restraining device for marmosets consists of three main parts:
Figure 2: Principal parts of restraint device. a-d = body of frame; e = angle bars with holes drilled for horizontal bar; hb = horizontal bar; vws = vertical wooden support for marmoset; hi = hinge with removable pin connecting vertical support to horizontal bar; ff == front fitting over lab bench. Not to scale.
Putting it together:
Figure 3: Wooden support for marmoset. a = plastic pipe; b = aluminum strip holding pipe to board. The end of the pipe is flush or almost flush with the end of the board. The strip is fastened to the board below the pipe with a countersunk screw (c). and covered with 5 rows of double-layered Velcro (the back pad, bp). At the top, the strip is folded 90 degrees over the end of the board and fastened there with another screw. d = abdominal fix (a long strap of Velcro); e = leg fixes (a Velcro strap fastened in the middle). Not to scale.
Important: The pipe should be slightly bigger than the marmoset, so there is no pressure of the marmoset’s body/back against the pipe. The purpose of the pipe is not to restrain the marmoset – the abdominal fix is for restraint – but to keep his/her head and arms out of the way. The marmoset’s hands, as well as his/her head, should protrude from the top of the pipe so that he/she can adjust his/her body, preventing pressure inside the pipe.
This pipe diameter is suitable for adults (weighing approximately 300-500 g), but smaller or larger pipe diameters can easily be fitted.

Using the Device
We emphasize at the outset that only personnel with appropriate skills and qualifications should attempt to handle and restrain marmosets. It is important for the marmosets to have positive human contact and interaction (e.g. positive reinforcement with frequent rewards), as this may help marmosets to cope better with handling and restraining procedures (Bassett et al., 2003). Taking the time to handle the marmosets gently and with due care is of paramount importance.
To use the restraint device, the marmoset is removed from the catch box by the handler. Holding the marmoset under the arms and around the hips, he/she can be guided up through the plastic tube allowing protrusion of his/her head and arms (see Figure 1). The Velcro waist strap is firmly fixed around the abdomen without causing discomfort. Both leg straps are then secured just above the knee joint. On removal from the device, the marmoset is supported across the abdomen after releasing the Velcro strap. Both Velcro leg straps are now released and the animal is removed by allowing him/her to push down or up the tube. Either way the animal is then held by holding under the arms and returned to the catch box.
Habituation and Desensitization to the Device
When using the device for the first time, about 50% of the marmosets appear very relaxed; they do not struggle, alarm vocalize, or seem distressed in any outward way. About 35% of marmosets show stress during handling and when first put into the restraint device, but relax thereafter. The remaining 15% remain vocal, and may struggle throughout the first session. However all will show varying levels of improvement over a period of one week into the blood sampling routine.
To habituate and desensitize, the marmoset is spoken to in a soft voice and marshmallow or other special reward is offered for remaining calm. The length of time the marmoset is restrained can be extended gradually. After this habituation and desensitization phase the marmoset can simply be rewarded at the end of the procedure before being placed back into the catch box.
Procedures that can be carried out in the device
Blood sampling: After strapping the marmoset into the device using the abdominal and leg straps as seen in Figure 1, the leg used for blood sampling is then released from the Velcro strap. This leg can be held straight by firmly placing four digits curled the length of the leg to ensure that the animal cannot bend at the knee or kick. The thumb is then placed to provide extra restraint and support to the syringe as the needle is placed at the appropriate angle into the vein as shown in Figure 5. The syringe needle should be inserted at an angle of approximately 15 degrees into the groove midway down the leg using the thumb as a guide. The vein or the groove is not always visible in heavier animals so the midpoint is always a good guide. The syringe plunger should be slowly pulled back just after insertion of the needle point and then the needle should be inserted further until blood is seen entering the needle hub. There should be no further insertion of the needle at this point. The plunger should be pulled slowly until the appropriate volume is acquired adhering to guidelines (e.g., in the U.K., the Animals Scientific Procedures Act, 1986).
Figure 5: The marmoset in the restraint device, with a blood sample being taken from her femoral vein.
After withdrawal of blood the thumb is placed across the point of needle insertion and moderate pressure applied before the needle is withdrawn. Thumb pressure should be applied for a minimum of 2-3 minutes after removing the needle. Alternatively swabs can be applied to prevent contamination of blood on gloves from one animal to the next.
An alternative method is to keep both legs strapped while taking the sampling. In this laboratory, blood samples of 300 µl are routinely drawn from the upper region of the femoral vein using a 27 g needle and a 1 ml heparinised syringe. It is best to alternate the collection between legs to allow for recovery of any trauma to the vein.
Method of semen collection from mated ovariectomised females or females on contraception: This method offers an alternative to electroejaculation for collection of semen samples. After visual proof of mating, the female is placed into the device as previously described. As shown in Figure 1, the wooden vertical support bar is fixed to the horizontal beam by means of a hinge. This hinge system allows the animal to be placed at any angle, and the optimum angle can be achieved by placing the beam on the operator’s shoulder (see Figure 6). Although the marmoset may feel vulnerable in the horizontal position, the duration of restraint at this angle is short (1-2 minutes), and the technique is considered a Refinement on electroejaculation that has traditionally been used for the collection of semen samples.
Figure 6: The hinged wooden beam is placed on the operator’s shoulders to allow the syringe to be gently inserted into the marmoset’s vaginal opening to collect semen. Once restrained, a cervical mucous sampling syringe can then be gently inserted approximately 1.5 cm into the vaginal opening, and the plunger pulled back while retracting the syringe. A flush or non-flushing method can be used. Flushing with a sperm medium should ensure maximum recovery of sperm. This sperm recovery method may be used for artificial insemination, or to evaluate semen quality and quantity.
Other potential uses: Other uses of the restraint device include trans-abdominal palpation for diagnosing and monitoring pregnancy, oral dosing procedures, and injections by various routes. Protective gloves and eye protection are recommended while carrying out all these procedures.

“Unpacking” the Variability of Metrics for Adult Male and Adult Female Mantled Howler Monkeys, Alouatta palliata
Clara B. Jones
Fayetteville State University
Alouatta (howler or howling monkey) is the most widely distributed primate genus in the Neotropics (A. Rylands, personal communication, 2005), found from northern Argentina to southern Mexico. Groves (2001) has recently divided howlers into ten species. Howler monkeys are arboreal folivore-frugivores, preferring new leaves, flowers, and fruit (Glander, 1975; Milton, 1980). These monkeys are adapted to environmental heterogeneity (Jones, 1995; Silver & Marsh, 2003), including climatic seasonality (Jones, 1997), a variable spatial and temporal food distribution (Jones, 1996), and a range of habitats (Jones, 1995; Groves, 2001, pp. 178-186). Environmental heterogeneity induces environmental uncertainty, unpredictability, and, possibly, risk (Piersma & Drent, 2003; Sih, 2004), factors thought to explain numerous traits exhibited by howlers (e.g., the presence or absence of birth peaks: see review in Jones, 2006, pp. 265-267). The purpose of the present note is to provide evidence for the view that the variability in weights observed for adult mantled howlers (Alouatta palliata; Figure 1) of both sexes can be “unpacked” and attributed to features of each group’s home range (“patch”), including habitat type. Although helpful analyses of mantled howler weights and other metrics can be found in the literature (e.g., Glander, 2006; Jones, 2006), I intend to show that fine-grained, within-group analyses of traits are required to “unpack” the variability of metrics across individuals in groups.
The study was conducted in the 1970s at Hacienda La Pacífica, Cañas, Guanacaste, Costa Rica (10° 28’ N, 85° 07’ W: see description in Glander, 1975), a ranch located within the Holdridge zone of tropical dry forest environment. As reported by the recognized authorities on Costa Rican forests (Frankie et al., 1974; Frankie et al., 2004), tropical dry forest environment is characterized by two habitats: riparian and deciduous. Both habitats are seasonal, with flower and fruit activity occurring primarily during the dry season, November through April.

In the deciduous habitat, leaf fall is synchronized for most trees during early to mid-dry season, and leaf flush occurs generally during the transition period from late dry to early wet season. In contrast, most trees in the riparian habitat retain their leaves throughout the year, displaying a pattern similar to wet forest sites in Costa Rica. In the present report, deciduous habitat is presumed to be most stressful for A. palliata because, when the two habitats are compared, deciduous is more strongly seasonal (Frankie et al., 1974), canopy cover is proportionately less (Jones, 2006), and primary productivity is probably lower (G. Frankie, personal communication, 2004). As a result, I hypothesized that the pattern of results reported here would be consistent with conditions of more food stress and energy constraints in the deciduous than in the riparian habitat group.
Mantled howler monkeys (Alouatta palliata), moderately large (maximum size ~7000 g) members of the family Atelidae, are distributed as three subspecies from northern South America to southern Mexico (Groves, 2001). The phenotypic plasticity of mantled howlers has been documented (Jones, 1995, 2003, 2005, 2006 and references; Glander, 2006), including within- and between-group variability in morphometric features (e.g., body weight). A. palliata populations generally live in highly communal and gregarious polygynandrous (multimale-multifemale) groups, although social organization may include polygynous and “age-graded” forms of sociosexual architecture (Crockett & Eisenberg, 1987).
The present report utilizes data for two marked groups occurring on home ranges in riparian and deciduous habitats (Jones, 1978, 1980). All data reported here were collected by Norman J. Scott, Jr. (U.S. Fish and Wildlife Service), and his assistants, including the author of the present article. Ages of adults were determined by tooth wear (Scott et al., 1976), and age classifications were defined as: young adult ~5 to 7 years old; middle-aged adults ~7 to 10 y; middle-aged to old ~10 to 15 y; and old > 15 y.
In the riparian habitat group, Y, a middle-aged male, was dominant. G, a young adult attempting to ascend the male hierarchy (Jones, 1980), was subordinate to Y. R, middle-aged to old, was subordinate to Y and G. In the deciduous habitat group, the young adult male, S, was dominant to Z, a middle-aged male. (In previous reports [e.g., Jones, 1980], Z was labeled “R12”. To avoid confusion with R of the riparian group, this deciduous group male has been relabeled Z. To avoid confusion with the female GS of the riparian habitat group, GS of the deciduous habitat group has been relabeled GMS.)
When animals were immobilized for marking and the recording of morphometric characteristics (e.g., tooth wear, weight), their physical condition (based upon the relative proportion of wounds, parasites, etc.) was rated on a four-interval scale from poor (0) to very good (4). For purposes of statistical analyses, a score of 1+ was converted to 1.5, a score of 2-, to 1.5, a score of 3+, to 3.5, etc. Data were analyzed with EcStatic software (Chalmer, 1990), and all tests are two-tailed with alpha set at 0.05.
Table 1 and Table 2 display characteristics of adult males and adult females in both groups. Reinspection of the original data sheets showed that “TC”, a female of the deciduous habitat group, was young, not middle-aged, as reported previously (e.g., Jones, 1980). No results of previous reports are changed as a result of this oversight.
On average, males of the riparian habitat group were significantly heavier than males of the deciduous habitat group (t(3.182) = 3.61, p < 0.05, df = 3). Female weight, on average, did not differ between groups (F(1, 16) = 0.49, p > 0.05. Neither male nor female condition differed by habitat, on average (males: t(3.182) = 0.41, p > 0.05; females: F(1, 15) = 2.91, p > 0.05).
|Weight (g)|| Physical|
Condition (0 – 4)
|Riparian Habitat Group|
|R||Middle-aged – Old||3||6630||3|
|Deciduous Habitat Group|
Within-group analyses were performed, and all variables were intercorrelated. Sample sizes for males were too small to conduct statistical tests. However, visual inspection suggests that rank is negatively associated with age and weight in both groups (high age and weight imply low rank) and that, within each group, male condition does not differ by more than a half-interval.
For females, three correlations were significant. In the riparian habitat group, rank and age are strongly negatively correlated (r= -0.80, p < 0.002, N= 11). In the same habitat, female rank is negatively correlated with weight (r= -0.64, p < 0.02, N= 11). For females in the deciduous habitat group, age is negatively correlated with condition (high age implies poor condition; r= -0.82, p < 0.02, N= 6). No other comparisons for either sex were statistically significant.
Schoener’s (1971) theoretical treatments showing that males are “time-minimizers”, females, “energy-maximizers”, have been employed in several reports on primate species (e.g., Jones, 1978, 1980, 2005, 2006; Wrangham, 1980; Smith, 1997). That male, but not female, weight differs by habitat in the present study is consistent with Schoener’s (1971) models since, all other things being equal, only females are expected to compete for food (Andersson, 1994). As my findings show, male weight conforms to the predicted energy (primary productivity) available in their habitat, with less energy available in the deciduous habitat. Females, on the other hand, are expected to compete for whatever threshold of body weight is required for successful reproduction, yielding little difference in weight, on average, between adults of this sex. Although recent research suggests that ecological constraints may influence female body size and, thus, weight (Jones, 2006), the present results are consistent with Jones’ (2003, 2006) findings for between-sex comparisons of weight in riparian and deciduous habitats.

In the deciduous habitat group, GS has been relabeled GMS to avoid confusion with GS of the riparian habitat group. See text for additional information and interpretation.
In an attempt to “unpack” the variability in weight within and between sites in Costa Rica and to control for inter-observer variability among these studies, it will be important for future primate studies in Costa Rica to employ the “Frankie classification system” for tropical dry forest environment (“riparian” and “deciduous”: Frankie et al., 1974, 2004) and to address the problem of independence of subjects in population surveys employing repeated sampling of the same population(s). In addition, it will be necessary for field researchers to calculate 95% confidence intervals around point estimates (Jones, 2001) in order to understand the meaning of sample means (e.g., mean weight).
Although within-group comparisons of two groups cannot confidently reveal broad patterns of animal response, these studies can document local effects (e.g., home range quality, and “microhabitat,” or “patch” effects). While the present findings suggest similar responses by males of both groups (i.e., that rank is negatively associated with age and weight and that male condition is similar between groups), within-group analyses of females, who are expected to be particularly responsive to habitat effects, show important differences. Females in the riparian habitat group exhibited a strong negative correlation between age and rank (low age implies high rank), consistent with Jones’ work on the “age-reversed” dominance system in this genus (1978, 1980, 1983). No such correlation was found in the deciduous habitat group, however, a finding explained by real differences between groups (e.g., home range quality, group size, coefficients of competition) or by sampling error. Females in the riparian habitat group also demonstrated a robust negative correlation between rank and weight (high rank implies lower weight), apparently similar to the male result. This finding may suggest that, in some conditions, howler females are not energetically stressed, or, simply, that low-ranking animals have more time than high-ranking individuals to devote to feeding, possibly because they are not performing key roles of dominants (e.g., policing), topics worthy of investigation. In the deciduous habitat group, only one significant result was found for females: younger females were in better condition than older ones. This result is consistent with my hypothesis that deciduous habitat is more stressful than riparian habitat, another topic requiring additional research and one that may have important implications for life history evolution (survivorship and fecundity: Jones, 1997).
My results support recent theoretical and empirical treatments showing the importance of local (“patch”) effects (e.g., within-group competition for food) for group features and emergent population characteristics (West et al., 2002). A survey of a primate population is a “snapshot” of responses and the architecture of these responses for a limited time period. Since these responses, and their thresholds, occur in particular local conditions (abiotic [e.g., humidity] and biotic, including social), it is critical for researchers conducting surveys of primate populations to specify and to measure or estimate these conditions during surveys for accurate identification of the likely causes of population parameters (mean, standard deviation), their prediction and control, their variability in space and time, and the association of conditions and individuals in groups (by sex) with features of populations (e.g., the multivariate relationship between humidity, resource dispersion, and local conspecific density relative to rates of aggression between sexes or, say, sex ratio of offspring). To date, no surveys of Neotropical primate populations meet these criteria.

Biofuel to Drive Indonesian Palm Oil Expansion
Indonesia’s government plans to develop 3 million hectares of palm oil plantations in the next five years to meet increasing demand for biofuel as an alternative source of energy, the agriculture minister said on Wednesday. Anton Apriyantono said two million hectares will be developed on the Kalimantan side of Borneo island and the rest in other parts of Indonesia.
The government said last year it will develop a new palm oil plantation in Kalimantan near the border with Malaysia. Covering an area of 1.8 million hectares, it has the potential to be the world’s biggest palm oil plantation. “The government targets to develop three million hectares in new palm oil plantations,” Apriyantono told reporters.
Biofuels are taking on renewed global importance as countries seek to avoid the soaring price of conventional oil and also cut hazardous emissions. Palm oil’s emergence in the market comes decades after the introduction of ethanol, made from sugarcane. Analysts say the biofuel push could be the biggest driver of growth in demand for vegetable oils, especially as palm oil is the cheapest vegetable oil and the easiest to convert into fuel.
Indonesia is the world’s second-largest palm oil producer and exporter after Malaysia. – Reuters News Service , January 27, 2006
Austria Enacts Ban on Ape Research
Effective January 2006, Austria has implemented legislation that prohibits any research on nonhuman apes that is not in the interest of the apes themselves. Austria has not used apes in research for several years, as the country’s research community retired their last chimpanzees used for research in 2002. However, this retirement presented the opportunity to discuss a research ban covering all nonhuman apes, including not just chimpanzees, bonobos, gorillas, and orangutans, but also eight species of gibbons. With its new ban, Austria joins New Zealand, the Netherlands, and Sweden, which have legislation and/or regulations that prohibit great ape research, and the United Kingdom, which has a policy of not granting licenses for such research. Japan has taken steps to ban invasive research on great apes, and Spain is currently considering a proposal to grant legal protection to great apes from “slavery, torture, death, and extinction”.
The United States is one of the few remaining countries to allow biomedical research and testing on great apes. In practice, chimpanzees are the only great ape currently used in U.S. research. The Humane Society of the United States (HSUS) has launched a campaign to end biomedical research and testing on chimpanzees. In 2000, the U.S. enacted legislation, supported by the HSUS, which designated a national sanctuary system for chimpanzees considered to be retired from research by the research community. – HSUS’ Animal Research News & Analysis, January, 2006

China’s Endangered Monkeys Make a Comeback
China’s golden monkeys, a species more endangered than giant pandas, have made a surprising comeback with populations quadrupling in the past two decades. The snub-nosed monkeys, which are found only in southwestern Guizhou province, have risen in number from 200 in the early 1980s to around 800, Xinhua news agency said. Despite its growing numbers, the animal is still endangered. Poaching and forest fires are two of the main causes for the decrease in population, according to Yang Yeqin, director of Guizhou’s Fanjingshan National Nature Reserve, where most of the monkeys live. The gregarious animals are also vulnerable to human diseases, such as tuberculosis, cholera and measles, Yang said. Researchers believe that the number of the snub-nosed monkeys would not rise rapidly even if their habitats were enlarged. However, the numbers would drop dramatically if their habitats dwindled, which may lead to their extinction, said the researchers. Wildlife experts said the animals’ living space must be extended, monitoring and protection of their environment must be strengthened, and a breeding base should be established to save the animals. – © 2006 Agence France Presse
CU Monkey Lab Closes, Gives Animals Away
The University of Colorado (CU) Health Sciences Center has decided to close its controversial monkey lab. About 40 monkeys have been used in experiments in AIDS, alcohol, and brain research. CU said most of the animals will go to Wake Forest University’s primate research facility and 10 will be given away to an animal rights group. School officials said the move will be beneficial for the research and the animals, who will get to spend some time outdoors in their new home. CU will oversee future experiments with the help of Wake Forest University, which is located in Winston-Salem, North Carolina.
Animal rights activists have expressed concern about the safety and security of the monkeys at the CU facility. In August 2004, they were successful in gaining the release of video from inside the lab. © Associated Press, February 16, 2006
Former Research Chimpanzees Leave for Florida
Ten chimpanzees from the former Coulston research facility began a 37-hour trip to Florida in a specially designed trailer. They are the first of 266 chimps that will be transported to Fort Pierce. The chimps once lived in a medical research laboratory in Alamogordo that was operated by Frederick Coulston, who helped develop or test treatments for malaria, hepatitis, and AIDS during a 72-year career.
In 2002, Coulston turned the animals over to Carole Noon, director of a recovery group called Save the Chimps. She said the animals will be introduced in Florida to a new colony of chimps and then will settle into an island home. “For the first time in their lives, they are going to walk on grass,” Noon said. “No walls, no roof.”
According to a news release from the organization, Save the Chimps operates the first sanctuary in the United States devoted exclusively to chimpanzees. It is the largest permanent chimpanzee sanctuary in the world. The facility provides lifetime care for chimpanzees taken from research laboratories and former chimp owners no longer able to provide adequate care.
It will take 27 trips to transport all the chimps from New Mexico to Florida. “We plan to have them all moved by the end of 2007,” Noon said. – Alamogordo Daily News, February 16, 2006
Chimp Dies after Transfer from Ohio
One of nine chimpanzees moved to a Texas sanctuary after Ohio State University decided to close a research center died after his transfer, school officials said. The 35-year-old male, named Kermit, stopped breathing Thursday after workers at Primarily Primates in San Antonio sedated him during a move from a transfer cage to living quarters, university spokesman Earle Holland said. Workers tried to resuscitate the chimp, but the university suspects Kermit’s head fell forward while he was sedated, blocking his airway. Obesity may have been a factor in the death of the 300-pound chimp, Holland said.
Ohio State veterinarians were to travel to San Antonio to check on the other chimps and meet with sanctuary officials and the veterinarian performing Kermit’s necropsy.
The other chimps were successfully sedated and doing fine, Holland said. Chimps can become violent when confronted by humans, so they are sedated when moved, he said.
These animals were a part of a cognitive studies program that has contributed to the understanding of chimpanzee intelligence. The program was directed by Dr. Sally Boysen, who has protested both the closing of program and the choice of sanctuary facility. OSU officials have stated that “in recent years, research funding for primate research across the country has been shrinking and university-based primate colonies are becoming harder to support.”
The university is paying $324,000 to build a facility at Primarily Primates and will provide an endowment for the chimps’ care. – Associated Press, March 5, 2006
Note from Sally Boysen: “When I have sought information from Primarily Primates about the chimps’ status, I have been told that ‘they do not have any information at this time’. I am hopeful we can resolve many of the unanswered questions soon. This group of, now eight, enculturated chimpanzees is of enormous scientific value, and the University has simply thrown the baby out with the bath water. I am very grateful for the caring and thoughtful responses from our friends and supporters in Columbus, Ohio, those around the country, and all my colleagues in the primate community during this very difficult time.”
Shelly Williams Paralyzed by Stray Bullet
Shelly Williams, of Smyrna, Georgia, was hit by a stray bullet in a parking lot in Smyrna on November 7. She is now paralyzed from the waist down. Smyrna police have issued arrest warrants for two men, Kendall Markell Bolden and Terrance D. Reid. Police believe Bolden fired the shot during a botched drug deal. A third man, Elliott Mitchell, who is now in prison in South Carolina on unrelated charges, was arrested earlier.
Before the shooting, Williams had planned to return to the Democratic Republic of Congo to continue her research. It was there, in the jungle, that a large animal she had never seen before walked in front of her. It wasn’t a chimpanzee, or a gorilla or a bonobo ape. This new creature seemed to have features of all three. She clicked her camera and captured the “unknown ape”. Other scientists are now trying to determine if the animal is a new ape species.
Within a month or two, she hopes she can change her clothes, go to the bathroom and take a shower — all by herself. She has gone through several operations, and spends her days undergoing physical and psychological therapy. She lifts weights to build strength in her arms so that she will be able to push the wheelchair. Her husband, Al Hofstetter, has been by her side every moment.
Once she gets better, she plans to write the long-overdue book detailing her work and research. With so much travel, there was never time. She hopes there will be time, too, to see that the men responsible are arrested, tried and convicted.
“I don’t have time to worry about getting justice until I am at my optimal best,” Williams said, “Whatever that may be.” – by Charles Yoo in The Atlanta Journal-Constitution, March 4, 2006
The primatology community extends its sympathy to Shelly at this very difficult time.

Grants Available: Effects of Antiretroviral Therapy on Oral Mucosa
The National Institute of Dental and Craniofacial Research (NIDCR), <www.nidcr.nih.gov>, seeks to stimulate research on the long term effects of antiretroviral therapy (ART) on, for example, the qualitative and quantitative composition of the saliva, innate and adaptive immune networks of the oral mucosa, and oral epithelial structures and functions. These studies will be restricted to the use of ex-vivo organotypic models of human oral mucosa, simian models for AIDS, and tissues from healthy individuals and AIDS patients receiving ART. Such research will provide valuable insight into the cellular and molecular mechanisms responsible for occurrence or recurrence of oral disorders in HIV-infected/AIDS patients, despite having been treated with ART. A goal of the initiative is to identify novel strategies for prevention and management of oral manifestations of HIV infection and AIDS by reducing the negative effects of ART.
Up to $700,000 total cost (direct costs plus facilities and administrative costs) may be awarded in support of this solicitation. Up to three new grants are anticipated to be funded. This funding opportunity announcement will use the NIH exploratory/development research grant (R21) award mechanism.

JWatcher 1.0 Released
Daniel T. Blumstein, of the Dept of Ecology and Evolutionary Biology at the University of California, Los Angeles, has announced the newest version of the event-recorder and analysis program JWatcher 1.0, which is designed to be used on 2006-era computers (Mac OS-X and Windows-XP). “Supported by a grant from the National Institute of Mental Health, JWatcher 1.0 adds new functionality and algorithms. Version 1.0 includes a number of additional algorithms that can be used to study sequences and study conditional behaviors (e.g., to study the frequency of, or time allocated to, walking while chewing gum), as well as algorithms to combine multiple results files into one summary file, and to study inter- or intra-observer reliability. Future releases will have integrated video scoring capabilities and the ability to score behavior on a PDA or Java-equipped device.
“Since releasing JWatcher 0.9 in November 2000, we have had thousands of downloads from all over the world. Neuroscientists, human factors experts, psychologists, and veterinarians have joined the many behavioral ecologists who use JWatcher to analyze their observations and experiments. We have taught thousands of students the fundamentals of quantifying animal behavior using JWatcher, and these labs at UCLA have been extremely popular. Educators in other institutions have used these labs to teach the process of quantifying behavior to their students. We’re very excited about our new release that updates JWatcher to make it more compatible with current versions of Java, as well as adding numerous new and powerful features. Our philosophy is to provide a free event recorder and analysis program to the research community. We are developing a book, “Analyzing behavior the JWatcher way,” and are instituting a paid support program to help you get the most out of JWatcher. We hope that JWatcher helps you solve your behavioral analysis problems.
“As a registered user, you will be updated first when we have new releases. Thanks for your interest and support of JWatcher. To download JWatcher, please go to the JWatcher Website: <www.jwatcher.ucla.edu>. For more information, contact me at 621 Charles E.

The Design of Animal Exercise Protocols
The American Physiological Society (APS) has just published a Resource Book for the Design of Animal Exercise Protocols. This book was developed during a series of meetings in 2003 and 2004 involving experts in the fields of exercise physiology and animal research models. It is intended for researchers, IACUCs, and those involved with research oversight.
The authoring committee, which was composed of exercise physiologists and laboratory animal veterinarians, reviewed reference material and drew upon their own experience to compile suggestions about how to design, review, and implement experimental paradigms involving animals and exercise. The Resource Book was peer-reviewed by other exercise physiologists and laboratory animal veterinarians. The PDF of the book is available at <www.the-aps.org/pa/action/exercise>.
Second Nonhuman Primate Genome Available
The National Human Genome Research Institute (NHGRI) announced on February 9 that a multi-center team has deposited the draft genome sequence of the rhesus macaque into free public databases for use by the worldwide research community.
The rhesus is the second nonhuman primate, after the chimpanzee, to have its genome sequenced, and is the first of the Old World monkeys to have its DNA deciphered. Overall, the rhesus genome shares about 92 to 95 percent of its sequence with that of the human and more than 98 percent with that of the chimpanzee. Consequently, the rhesus provides an ideal reference point for comparisons among three closely related primates. Sequencing is also underway on the genomes of a number of other primates, including the orangutan, marmoset, and gorilla.
The sequencing of the rhesus genome was conducted at the Baylor College of Medicine Human Genome Sequencing Center in Houston, the Genome Sequencing Center at Washington University in St. Louis, and at the J. Craig Venter Institute in Rockville, Maryland, which are part of the NHGRI-supported Large-Scale Sequencing Research Network. The DNA samples used in the sequencing came from a female rhesus macaque at the Southwest Foundation for Biomedical Research in San Antonio.
The research community can access the sequence data through GenBank <www.ncbi.nih.gov/Genbank>; Map Viewer <www.ncbi.nlm.nih.gov/mapview>; EMBL Bank <www.ebi.ac.uk/embl>; DNA Data Bank of Japan <www.ddbj.nig.ac.jp>; the UCSC Genome Browser <www.genome.ucsc.edu>; and the Ensembl Genome Browser <www.ensembl.org>. at the Wellcome Trust Sanger Inst. in Cambridge, England. Additional information about the rhesus sequence is available through the Human Genome Sequence Center at Baylor College of Medicine <www.hgsc.bcm.tmc.edu>.

* Monkey Farm: A History of the Yerkes Laboratories of Primate Biology, Orange Park, Florida, 1930-1965. D. A. Dewsbury. Lewisburg, PA: Bucknell University Press, 2006. [Price: $55]
. . . The “Monkey Farm” was founded as the Laboratories of Comparative Psychobiology of Yale University by Robert M. Yerkes. During its 35-year history, the Yerkes Laboratories became the largest and most important collection of chimpanzees for research in the world and was home to some of the leading behavioral scientists of the time. After 11 years, Robert Yerkes retired as director and was succeeded by Karl Lashley, and the laboratories came under the joint sponsorship of Harvard and Yale. In 1956 sponsorship was shifted to Emory University. With the founding of a well-funded program of Regional Primate Research Centers by the federal government, Emory officials decided to seek Primate Center status and move the Laboratories to their home campus in Atlanta, Georgia. This period of the Laboratories’ life, 1930-1965, coincides with the period of fundamental change in patronage for science in the United States. Thus, the history of this facility can be seen as a case study of the impact of this fundamental change on a scientific institution from dominance by private foundations to that of federal funding for research.

* Testing for localized stimulus enhancement and object movement reenactment in pig-tailed macaques (Macaca nemestrina) and young children (Homo sapiens). Rigamonti, M. M., Custance, D. M., Previde, E. P., & Spiezio, C. (Centro Di Primatologia HSR, Via Olgettina, 60, Milan 20132, Italy [e-mail: firstname.lastname@example.org]). Journal of Comparative Psychology, 2005, 119, 257-272.
. . . Four puzzle boxes were used to investigate localized stimulus enhancement and object movement reenactment (OMR) in 13 pig-tailed macaques and 30 human infants. Participants received contrasting demonstrations on each box. A circular lid was gripped by its rim or handle and swiveled to the left or right. A flap door was pushed or flipped. A sliding lid was pushed to the left or right. A pin bolt was demonstrated being pushed down, or the participants were left to solve the puzzle for themselves. Despite the fact that the monkeys watched the demonstrations about 60% of the time, only a weak OMR effect was found on the sliding lid. In contrast, the children watched significantly more, and there was clear evidence of socially mediated learning on all of the boxes.
* Adaptation of Plasmodium vivax to growth in owl monkeys (Aotus nancymai). Williams, A. M., Barefield, S. J., Carter, E. R., Collins, W. E., Sullivan, J. S., & Tate, M. K. (4770 Buford Hwy MSF33, Bldg 15, Chamblee, GA 30341). Comparative Medicine, 2005, 55, 528-532.
. . . A need arose for malarial parasites for use in serologic and molecular studies and for teaching slides. This particular strain of parasite had been characterized previously as producing high-density parasitemia in splenectomized New World monkeys and therefore represented a good candidate for reactivation. P. vivax (Vietnam II), isolated in 1970, was reactivated after adaptation in Aotus lemurinus griseimembra monkeys nearly 33 years earlier and adapted to A. nancymai monkeys. Passage was achieved by intravenous inoculation of parasite blood stages into splenectomized A. nancymai monkeys. Parasitemia was determined by analyzing daily blood smears stained with Giemsa. Maximum parasite counts ranged from 10,630 to 94,000 parasites/microl; the mean maximum parasite count for the four animals was 39,565 parasites/microl. Parasite counts of > 10,000/microl were maintained for 2 to 64 days. After only three passages of the parasite, attempts to reactive were successful. A. nancymai proved a suitable animal model for the recovery of this parasite. In conclusion, successful reactivation and adaptation of this parasite offers the capability to perform a series of diagnostic, immunologic, and molecular studies as well as to provide otherwise potentially unavailable teaching materials to healthcare professionals.
* A T-cell HCV vaccine eliciting effective immunity against heterologous virus challenge in chimpanzees. Folgori, A., Capone, S., Ruggeri, L., Meola, A., Sporeno, E., Ercole, B. B., Pezzanera, M., Tafi, R., Arcuri, M., Fattori, E., Lahm, A., Luzzago, A., Vitelli, A., Colloca, S., Cortese, R., & Nicosia, A. (A. N., Ist. di Ricerche di Biol. Mol. “P. Angeletti,” via Pontina km30,600, 00040 Pomezia, Rome, Italy [e-mail: email@example.com]). Nature Medicine, 2006, 12, 190-197.
. . . “Three percent of the world’s population is chronically infected with the hepatitis C virus (HCV) and at risk of developing liver cancer. Effective cellular immune responses are deemed essential for spontaneous resolution of acute hepatitis C and long-term protection. Here we describe a new T-cell HCV genetic vaccine capable of protecting chimpanzees from acute hepatitis induced by challenge with heterologous virus. Suppression of acute viremia in vaccinated chimpanzees occurred as a result of massive expansion of peripheral and intrahepatic HCV-specific CD8+ T lymphocytes that cross-reacted with vaccine and virus epitopes. These findings show that it is possible to elicit effective immunity against heterologous HCV strains by stimulating only the cellular arm of the immune system, and suggest a path for new immunotherapy against highly variable human pathogens like HCV, HIV or malaria, which can evade humoral responses.”
* The primate amygdala represents the positive and negative value of visual stimuli during learning. Paton, J. J., Belova, M. A., Morrison, S. E., & Salzman, C. D. (C. D. S., Columbia Univ., 1051 Riverside Dr., Unit 87, New York, NY 10032 [e-mail: firstname.lastname@example.org]). Nature, 2006, 439, 865-870.
. . . “Visual stimuli can acquire positive or negative value through their association with rewards and punishments, a process called reinforcement learning. Although we now know a great deal about how the brain analyses visual information, we know little about how visual representations become linked with values. To study this process, we turned to the amygdala, a brain structure implicated in reinforcement learning. We recorded the activity of individual amygdala neurons in monkeys while abstract images acquired either positive or negative value through conditioning. After monkeys had learned the initial associations, we reversed image value assignments. We examined neural responses in relation to these reversals in order to estimate the relative contribution to neural activity of the sensory properties of images and their conditioned values. Here we show that changes in the values of images modulate neural activity, and that this modulation occurs rapidly enough to account for, and correlates with, monkeys’ learning. Furthermore, distinct populations of neurons encode the positive and negative values of visual stimuli. Behavioral and physiological responses to visual stimuli may therefore be based in part on the plastic representation of value provided by the amygdala.”
* Maternal mediation, stress inoculation, and the development of neuroendocrine stress resistance in primates. Parker, K. J., Buckmaster, C. L., Sundlass, K., Schatzberg, A. F., & Lyons, D. M. (Dept of Psychiatry & Behavioral Sci., Stanford Univ., 1201 Welch Rd, MSLS P104, Stanford, CA 94305-5485 [e-mail: email@example.com]). Proceedings of the National Academy of Sciences, U.S.A., 2006, 103, 3000-3005.
. . . “The stress inoculation hypothesis presupposes that brief intermittent stress exposure early in life induces the development of subsequent stress resistance in human and nonhuman primates. Rodent studies, however, suggest a role for maternal care rather than stress exposure per se (i.e., the maternal mediation hypothesis). To investigate these two hypotheses, we examined maternal care and the development of stress resistance after exposure to brief intermittent infant stress (IS), mother–infant stress (MIS), or no stress (NS) protocols administered to 30 monkeys between postnatal weeks 17 and 27. Unlike rodents, the IS condition did not permanently increase primate maternal care, nor did measures of total maternal care predict subsequent offspring hypothalamic–pituitary–adrenal-axis responsivity. Although MIS infants received less maternal care than IS and NS infants, both IS and MIS monkeys developed subsequent stress resistance. These findings indicate that rearing differences in the development of stress resistance are more closely related to differences in prior stress exposure than to differences in maternal care. A second experiment confirmed this conclusion in a different cohort of 25 monkeys exposed as infants to high foraging-demand (HFD) or low foraging-demand (LFD) conditions. HFD infants exhibited intermittent elevations in cortisol levels and received less maternal care than LFD infants. In keeping with a key prediction of the stress inoculation hypothesis, HFD males responded to stress in adulthood with diminished hypothalamic–pituitary–adrenal-axis activation compared with LFD males. Results from both experiments demonstrate that stress inoculation, rather than high levels of maternal care, promotes the development of primate stress resistance.”
* Prolonged diabetes reversal after intraportal xenotransplantation of wild-type porcine islets in immunosuppressed nonhuman primates. Hering, B. J., Wijkstrom, M., Graham, M. L., Hårdstedt, M., Aasheim, T. C., Jie, T., Ansite, J. D., Nakano, M., Cheng, J., Li, W., Moran, K., Christians, U., Finnegan, C., Mills, C. D., Sutherland, D. E., Bansal-Pakala, P., Murtaugh, M. P., Kirchhof, N., & Schuurman, H.-J. (Diabetes Inst. for Immunology and Transplantation, Dept of Surgery, Univ. of Minnesota, 424 Harvard St SE, Minneapolis, MN 55455 [e-mail: firstname.lastname@example.org]). Nature Medicine, 2006, 12, 301-303.
. . . “Cell-based diabetes therapy requires an abundant cell source. Here, we report reversal of diabetes for more than 100 d in cynomolgus macaques after intraportal transplantation of cultured islets from genetically unmodified pigs without Gal-specific antibody manipulation. Immunotherapy with CD25-specific and CD154-specific monoclonal antibodies, FTY720 (or tacrolimus), everolimus and leflunomide suppressed indirect activation of T cells, elicitation of non-Gal pig-specific IgG antibody, intragraft expression of proinflammatory cytokines and invasion of infiltrating mononuclear cells into islets.”
* Long-term survival of neonatal porcine islets in nonhuman primates by targeting costimulation pathways. Cardona, K., Korbutt, G. S., Milas, Z., Lyon, J., Cano, J., Jiang, W., Bello-Laborn, H., Hacquoil, B., Strobert, E., Gangappa, S., Weber, C. J., Pearson, T. C., Rajotte, R. V., & Larsen, C. P. (R. V. R., Surgical-Medical Research Inst., Univ. of Alberta, 1074 Dentistry/Pharmacy Ctr., Edmonton, Alberta, T6G 2N8, Canada [e-mail: email@example.com]). Nature Medicine, 2006, 12, 304-306.
. . . “We evaluated the ability of neonatal porcine islets to engraft and restore glucose control in pancreatectomized rhesus macaques. Although porcine islets transplanted into nonimmunosuppressed macaques were rapidly rejected by a process consistent with cellular rejection, recipients treated with a CD28-CD154 costimulation blockade regimen achieved sustained insulin independence (median survival, >140 days) without evidence of porcine endogenous retrovirus dissemination. Thus, neonatal porcine islets represent a promising solution to the crucial supply problem in clinical islet transplantation.”
* Cooperative problem solving by tufted capuchin monkeys (Cebus apella): Spontaneous division of labor, communication, and reciprocal altruism. Hattori, Y., Kuroshima, H., & Fujita, K. (Dept of Psychology, Grad. Sch. of Letters, Yoshida-honmachi, Kyoto 606-8501, Japan [e-mail: Yuko.Hattori@L03.mbox.media.kyoto-u.ac.jp]). Journal of Comparative Psychology, 2005, 119, 335-342.
. . . Using an experimentally induced cooperation task, the authors investigated whether tufted capuchin monkeys share the following three characteristics of cooperation with humans: division of labor, communication, and reciprocal altruism. In Experiment 1, the authors trained individual monkeys to perform the necessary sequence of actions for rewards and tested them in pairs to assess whether they could solve the task by spontaneously dividing the sequence of actions. All pairs solved this task. In Experiment 2, monkeys worked in the cooperation task and a task requiring no partner help. They looked at the partner significantly longer in the former task than in the latter, but communicative intent could not be determined. In Experiment 3, only one of two participants obtained a reward on each trial. Monkeys maintained cooperation when their roles were reversed on alternate trials. Their cooperative performances demonstrated division of labor; results suggest task-related communication and reciprocal altruism.
* The win-stay rule in foraging decisions by free-ranging titi monkeys (Callicebus cupreus cupreus) and tamarins (Saguinus imperator imperator and Saguinus fuscicollis weddelli). Bicca-Marques, J. C. (Fac. de Biociências, Pontifícia Univ. Católica do Rio Grande do Sul, Av. Ipiranga 6681 Pd 12A, Porto Alegre, RS 90619-900, Brazil [e-mail: firstname.lastname@example.org]). Journal of Comparative Psychology, 2005, 119, 343-351.
. . . Rainforest primates need to apply distinct foraging rules for efficiently using the spatial knowledge of the distribution of resources showing different temporal patterns of renewal. A win-stay rule is very important for exploiting abundant, long-lasting resources. Here, the author tests the use of this rule in wild groups of emperor tamarins, saddle-back tamarins, and titi monkeys during a series of foraging tasks. Four feeding stations composed of 8 visually similar feeding platforms (2 containing a food reward and 6 containing a sham reward) were constructed. The location of food rewards was reliable during some experiments and unreliable during others. All three species consistently adopted a win-stay rule for returning to reward platforms when their location was predictable over time but stopped using it when their spatial distribution changed randomly across experimental trials.
* Factors influencing the prevalence and handedness for throwing in captive chimpanzees (Pan troglodytes). W. D. Hopkins, J. L. Russell, C. Cantalupo, H. Freeman, & S. J. Schapiro (Div. of Psychobiol., Yerkes NPRC, Emory Univ., 954 Gatewood Rd, Atlanta, GA 30322 [e-mail: email@example.com]). Journal of Comparative Psychology, 2005, 119, 363-370.
. . . Humans throw right-handed, and it has been suggested that the neurophysiological demands of aimed throwing may have served as a precursor to the evolution of left hemisphere specialization for linguistic functions. Although there are descriptions of throwing by wild and captive chimpanzees, systematic observations of aimed throwing and handedness have not been reported. In this article, evidence of population-level right-handedness for throwing is reported in two samples of captive chimpanzees. It is further reported that right-handed throwing is more pronounced than other measures of handedness in captive chimpanzees. The implications of these findings are discussed in the context of theories relating throwing to the evolution of lateralization for language functions.
* Attention to combined attention in New World monkeys (Cebus apella, Saimiri sciureus). J. R. Anderson, H. Kuroshima, Y. Hattori, & K. Fujita (Dept of Psychology, Univ. of Stirling, Stirling FK9 4LA, Scotland [e-mail: firstname.lastname@example.org]). Journal of Comparative Psychology, 2005, 119, 461-464.
. . . Co-orientation by capuchin and squirrel monkeys was recorded in response to familiar humans abruptly switching the direction of their visual attention. Co-orientation occurred more frequently overall in capuchins than squirrel monkeys. Capuchins showed a tendency to habituate within trials involving consecutive attention switches performed by two different people, whereas squirrel monkeys co-oriented more when the second attention switch was by a second actor. These results suggest variable attention-processing abilities in New World monkeys, including differences in summation of attention by others.
* Policing stabilizes construction of social niches in primates. Flack, J. C., Girvan, M., de Waal, F. B. M., & Krakauer, D. C. (Santa Fe Inst., Santa Fe, NM 87501 [e-mail: email@example.com]). Nature, 2006, 439, 426-429.
. . . “All organisms interact with their environment, and in doing so shape it, modifying resource availability. Termed niche construction, this process has been studied primarily at the ecological level with an emphasis on the consequences of construction across generations. We focus on the behavioral process of construction within a single generation, identifying the role a robustness mechanism—conflict management—has in promoting interactions that build social resource networks or social niches. Using ‘knockout’ experiments on a large, captive group of pigtailed macaques (Macaca nemestrina), we show that a policing function, performed infrequently by a small subset of individuals, significantly contributes to maintaining stable resource networks in the face of chronic perturbations that arise through conflict. When policing is absent, social niches destabilize, with group members building smaller, less diverse, and less integrated grooming, play, proximity and contact-sitting networks. Instability is quantified in terms of reduced mean degree, increased clustering, reduced reach, and increased assortativity. Policing not only controls conflict, we find it significantly influences the structure of networks that constitute essential social resources in gregarious primate societies. The structure of such networks plays a critical role in infant survivorship, emergence and spread of cooperative behavior, social learning and cultural traditions.”
* Chimpanzees recruit the best collaborators. Melis, A. P., Hare, B., & Tomasello, M. (Max Planck Inst. for Evolutionary Anthropol., Leipzig, D-04103, Germany [e-mail: firstname.lastname@example.org]). Science, 2006, 311, 1297-1300.
. . . “Humans collaborate with non-kin in special ways, but the evolutionary foundations of these collaborative skills remain unclear. We presented chimpanzees with collaboration problems in which they had to decide when to recruit a partner and which potential partner to recruit. In an initial study, individuals recruited a collaborator only when solving the problem required collaboration. In a second study, individuals recruited the more effective of two partners on the basis of their experience with each of them on a previous day. Therefore, recognizing when collaboration is necessary and determining who is the best collaborative partner are skills shared by both chimpanzees and humans, so such skills may have been present in their common ancestor before humans evolved their own complex forms of collaboration.”

* Resistance of Plasmodium falciparum field isolates to in-vitro artemether and point mutations of the SERCA-type PfATPase6. Jambou, R., Legrand, E., Niang, M., Khim, N., Lim, P., Volney, B., Ekala, M. T., Bouchier, C., Esterre, P., Fandeur, T., & Mercereau-Puijalon, O. (Inst. Pasteur de Dakar, 36 Ave. Pasteur, Unité d’Immunologie, P.O. Box 220, Dakar, Senegal [e-mail: email@example.com]). Lancet, 2005, 366, 1960-1963.
. . . “Artemisinin derivatives are an essential component of treatment against multidrug-resistant Plasmodium falciparum malaria. We aimed to investigate in-vitro resistance to artemisinin derivatives in field isolates. In-vitro susceptibility of 530 P. falciparum isolates from three countries (Cambodia, French Guiana, and Senegal) with different artemisinin use was assessed with an isotopic microtest. Artemether IC50 up to 117 and 45 nmol/L was seen in French Guiana and Senegal, respectively. DNA sequencing in a subsample of 60 isolates lends support to SERCA-PfATPase6 as the target for artemisinins. The S769N PfATPase6 mutation, noted exclusively in French Guiana, was associated with raised (> 30 nmol/L) artemether IC50s (p < 0*0001, Mann-Whitney). All resistant isolates came from areas with uncontrolled use of artemisinin derivatives. This rise in resistance indicates the need for increased vigilance and a coordinated and rapid deployment of drug combinations.”
* Gene-specific countermeasures against ebola virus based on antisense phosphorodiamidate morpholino oligomers. Warfield, K. L., Swenson, D. L., Olinger, G. G., Nichols, D. K., Pratt, W. D., Blouch, R., Stein, D. A., Aman, M. J., Iversen, P. L., & Bavari, S. (S. B., USAMRIID, Fort Detrick, Frederick, MD 21701 [e-mail: firstname.lastname@example.org]). PLOS Pathogens, 2006 2(1); <pathogens.plosjournals.org>.
. . . The filoviruses Marburg virus and Ebola virus (EBOV) quickly outpace host immune responses and cause hemorrhagic fever, resulting in case fatality rates as high as 90% in humans and nearly 100% in nonhuman primates. The development of an effective therapeutic for EBOV is a daunting public health challenge and is hampered by a paucity of knowledge regarding filovirus pathogenesis. This report describes a successful strategy for interfering with EBOV infection using antisense phosphorodiamidate morpholino oligomers (PMOs). A combination of EBOV-specific PMOs targeting sequences of viral mRNAs for the viral proteins (VPs) VP24, VP35, and RNA polymerase L protected rodents in both pre- and post-exposure therapeutic regimens. In a prophylactic proof-of-principal trial, the PMOs also protected 75% of rhesus macaques from lethal EBOV infection. The work described here may contribute to development of designer, “druggable” countermeasures for filoviruses and other microbial pathogens.
* Disseminate cryptococcosis in a guenon (Cercopithecus ascanius). Helke, K. L., Denver, M. C., Bronson, E., & Mankowski, J. L. (J. L. M., Johns Hopkins Univ. School of Medicine, Dept of Comp. Med., 733 N. Broadway, BRB 835, Baltimore, MD 21205-2196 [e-mail: jmankows@ jhmi.edu]). Veterinary Pathology, 2006, 43, 75-78.
. . . A 23-year-old captive-bred red-tailed guenon with a brief history of inappetence, lethargy, and seizures was submitted for necropsy. On postmortem examination, multiple cryptococcomas were identified in brain and heart. Cryptococcus neoformans organisms were also identified microscopically in kidney, eye, and pancreas. Fungal yeast formed rare pseudohyphae. The histologic diagnosis of cryptococcosis was confirmed by a positive test for C. neoformans antigen in a serum sample. Immunohistochemical staining confirmed that macrophages were the principal inflammatory cell in brain lesions and often contained phagocytosed yeast. As disseminate cryptococcosis is often associated with immune suppression, serology and immunohistochemical staining for simian immunodeficiency virus were performed but showed no evidence of SIV infection.
* A new bacillus anthracis found in wild chimpanzees and a gorilla from West and Central Africa. Leendertz, F. H., Yumlu, S., Pauli, G., Boesch, C., Couacy-Hymann, E., Vigilant, L., Junglen, S., Schenk, S., & Ellerbrok, H. (H. E., Robert Koch-Institut, Center for Biological Safety, Berlin, Germany [e-mail: EllerbrokH@rki.de]). PLoS Pathogens, 2006, 2; <pathogens.plosjournals.org>.
. . . “We determined that anthrax infection caused the sudden deaths of six wild chimpanzees in the Taï National Park, Côte d’Ivoire in 2001/2002 and in three chimpanzees and one gorilla found dead more than 1,000 mi to the east, at the northern periphery of the Dja Reserve, Cameroon, in 2004/2005. In order to characterize the B. anthracis isolates from a totally new habitat that were responsible for the death of wild great apes that died in Côte d’Ivoire and Cameroon, we performed VNTR analyses on DNA isolated from tissue samples and bones of these great apes. Surprisingly, for the isolates from both outbreaks, three of the six genomic VNTRs were clearly different from those of any previously described strain, as is evident from the phylogenetic tree analysis. The strain from Côte d’Ivoire, named B. anthracis CI (Côte d’Ivoire), and the strain from Cameroon, named B. anthracis CA (Cameroon) are clearly distinct from group A and group B strains. They establish a separate branch with a new ‘forest anthrax cluster’, termed ‘F’, suggesting that B. anthracis is a far less homogeneous species than is currently believed. No differences were found among the six cases from Côte d’Ivoire, and also the four anthrax isolates from the three chimpanzees and the gorilla from Cameroon were identical.”
* Antiviral treatment is more effective than smallpox vaccination upon lethal monkeypox virus infection. Stittelaar, K. J., Neyts, J., Naesens, L., van Amerongen, G., van Lavieren, R. F., Holý, A., De Clercq, E., Niesters, H. G. M., Fries, E., Maas, C., Mulder, P. G. H., van der Zeijst, B. A. M., & Osterhaus, A. D. M. E. (A.D.M.E.O., Department of Virology, Erasmus MC, 3000 DR Rotterdam, The Netherlands [e-mail: email@example.com]). Nature, 2006, 439, 745-748.
. . . “There is concern that variola virus, the aetiological agent of smallpox, may be used as a biological weapon. For this reason several countries are now stockpiling (vaccinia virus-based) smallpox vaccine. Although the preventive use of smallpox vaccination has been well documented, little is known about its efficacy when used after exposure to the virus. Here we compare the effectiveness of (1) post-exposure smallpox vaccination and (2) antiviral treatment with either cidofovir (also called HPMPC or Vistide) or with a related acyclic nucleoside phosphonate analogue (HPMPO–DAPy) after lethal intratracheal infection of cynomolgus monkeys (Macaca fascicularis) with monkeypox virus (MPXV). MPXV causes a disease similar to human smallpox and this animal model can be used to measure differences in the protective efficacies of classical and new-generation candidate smallpox vaccines. We show that initiation of antiviral treatment 24 h after lethal intratracheal MPXV infection, using either of the antiviral agents and applying various systemic treatment regimens, resulted in significantly reduced mortality and reduced numbers of cutaneous monkeypox lesions. In contrast, when monkeys were vaccinated 24 h after MPXV infection, using a standard human dose of a currently recommended smallpox vaccine (Elstree-RIVM), no significant reduction in mortality was observed. When antiviral therapy was terminated 13 days after infection, all surviving animals had virus-specific serum antibodies and antiviral T lymphocytes. These data show that adequate preparedness for a biological threat involving smallpox should include the possibility of treating exposed individuals with antiviral compounds such as cidofovir or other selective anti-poxvirus drugs.”
Evolution, Genetics, and Taxonomy
* Ancient and recent positive selection transformed opioid cis-regulation in humans. Rockman, M. V., Hahn, M. W., Soranzo, N., Zimprich, F., Goldstein, D. B., & Wray, G. A. Dept of Biology, Duke Univ., Durham, NC [e-mail: firstname.lastname@example.org]). PLoS Biology, 2005, 3; <biology.plosjournals.org>.
. . . “Changes in the cis-regulation of neural genes likely contributed to the evolution of our species’ unique attributes, but evidence of a role for natural selection has been lacking. We found that positive natural selection altered the cis-regulation of human prodynorphin, the precursor molecule for a suite of endogenous opioids and neuropeptides with critical roles in regulating perception, behavior, and memory. Independent lines of phylogenetic and population genetic evidence support a history of selective sweeps driving the evolution of the human prodynorphin promoter. In experimental assays of chimpanzee-human hybrid promoters, the selected sequence increases transcriptional inducibility. The evidence for a change in the response of the brain’s natural opioids to inductive stimuli points to potential human-specific characteristics favored during evolution. In addition, the pattern of linked nucleotide and microsatellite variation among and within modern human populations suggests that recent selection, subsequent to the fixation of the human-specific mutations and the peopling of the globe, has favored different prodynorphin cis-regulatory alleles in different parts of the world.”
* Morphological affinities of the Sahelanthropus tchadensis (Late Miocene hominid from Chad) cranium. Guy, F., Lieberman, D. E., Pilbeam, D., Ponce de León, M., Likius, A., Mackaye, H. T., Vignaud, P., Zollikofer, C., & Brunet, M. (D. P., Peabody Museum, Harvard University, 11 Divinity Avenue, Cambridge, MA [e-mail: email@example.com]). Proceedings of the National Academy of Sciences, U.S.A., 2005, 102, 18836-18841.
. . . “The recent reconstruction of the Sahelanthropus tchadensis cranium (TM 266-01-60-1) provides an opportunity to examine in detail differences in cranial shape between this earliest-known hominid, African apes, and other hominid taxa. Here we compare the reconstruction of TM 266-01-60-1 with crania of African apes, humans, and several Pliocene hominids. The results not only confirm that TM 266-01-60-1 is a hominid but also reveal a unique mosaic of characters. The TM 266-01-60-1 reconstruction shares many primitive features with chimpanzees but overall is most similar to Australopithecus, particularly in the basicranium. However, TM 266-01-60-1 is distinctive in having the combination of a short subnasal region associated with a vertical upper face that projects substantially in front of the neurocranium. Further research is needed to determine the evolutionary relationships between Sahelanthropus and the known Miocene and Pliocene hominids.”
* Placing confidence limits on the molecular age of the human-chimpanzee divergence. Kumar, S., Filipski, A., Swarna, V., Walker, A., & Hedges, S. B. (Biodesign Building A-240, Arizona State Univ., Tempe, AZ 85287-5301 [e-mail: firstname.lastname@example.org]). Proceedings of the National Academy of Sciences, U.S.A., 2005, 102, 18842-18847.
. . . “Molecular clocks have been used to date the divergence of humans and chimpanzees for nearly four decades. Nonetheless, this date and its confidence interval remain to be firmly established. In an effort to generate a genomic view of the human-chimpanzee divergence, we have analyzed 167 nuclear protein-coding genes and built a reliable confidence interval around the calculated time by applying a multifactor bootstrap-resampling approach. Bayesian and maximum likelihood analyses of neutral DNA substitutions show that the human–chimpanzee divergence is close to 20% of the ape-Old World monkey (OWM) divergence. Therefore, the generally accepted range of 23.8-35 millions of years ago for the ape-OWM divergence yields a range of 4.98-7.02 millions of years ago for human-chimpanzee divergence. Thus, the older time estimates for the human-chimpanzee divergence, from molecular and paleontological studies, are unlikely to be correct. For a given ape-OWM divergence time, the 95% confidence interval of the human-chimpanzee divergence ranges from -12% to 19% of the estimated time. Computer simulations suggest that the 95% confidence intervals obtained by using a multifactor bootstrap-resampling approach contain the true value with >95% probability, whether deviations from the molecular clock are random or correlated among lineages. Analyses revealed that the use of amino acid sequence differences is not optimal for dating human-chimpanzee divergence and that the inclusion of additional genes is unlikely to narrow the confidence interval significantly. We conclude that tests of hypotheses about the timing of human-chimpanzee divergence demand more precise fossil-based calibrations.”
* Variable molecular clocks in hominoids. Elango, N., Thomas, J. W., NISC Comparative Sequencing Program, & Yi, S. V. (S. V. Y., School of Biology, Georgia Institute of Technology, Atlanta, GA 30332 [e-mail: email@example.com]). Proceedings of the National Academy of Sciences, USA, 2006, 103, 1370-1375
. . . “Generation time is an important determinant of a neutral molecular clock. There are several human-specific life history traits that led to a substantially longer generation time in humans than in other hominoids. Indeed, a long generation time is considered an important trait that distinguishes humans from their closest relatives. Therefore, humans may exhibit a significantly slower molecular clock as compared to other hominoids. To investigate this hypothesis, we performed a large-scale analysis of lineage-specific rates of single-nucleotide substitutions among hominoids. We found that humans indeed exhibit a significant slowdown of molecular evolution compared to chimpanzees and other hominoids. However, the amount of fixed differences between humans and chimpanzees appears extremely small, suggesting a very recent evolution of human-specific life history traits. Notably, chimpanzees also exhibit a slower rate of molecular evolution compared to gorillas and orangutans in the regions analyzed.”
* Body size, body proportions, and encephalization in a Middle Pleistocene archaic human from northern China. Rosenberg, K. R., Zuné, L., & Ruff, C. B. (Dept of Anthropology, Univ. of Delaware, Newark, DE 19716 [e-mail: firstname.lastname@example.org]). Proceedings of the National Academy of Sciences, U.S.A., 2006, 103, 3552-3556.
. . . The unusual discovery of associated cranial and postcranial elements from a single Middle Pleistocene fossil human allows us to calculate body proportions and relative cranial capacity (encephalization quotient) for that individual rather than rely on estimates based on sample means from unassociated specimens. The individual analyzed here (Jinniushan) from northeastern China at 260,000 years ago is the largest female specimen yet known in the human fossil record and has body proportions (body height relative to body breadth and relative limb length) typical of cold-adapted populations elsewhere in the world. Her encephalization quotient of 4.15 is similar to estimates for late Middle Pleistocene humans that are based on mean body size and mean brain size from unassociated specimens.
Instruments and Techniques
* Safe and efficient collection of cytokine-mobilized peripheral blood cells from cynomolgus monkeys (Macaca fascicularis) with human newborn-equivalent body weights. Ageyama, N., Hanazono, Y., Shibata, H., Ono, F., Ogawa, H., Nagashima, T., Ueda, Y., Yoshikawa, Y., Hasegawa, M., Keiya Ozawa, K., & Terao, K. (Tsukuba Primate Research Center, 1 Hachimandai, Tsukuba, Ibaraki 305-0843, Japan [e-mail: email@example.com]). Experimental Animals, 2005, 54, 421-428.
. . . “Hematopoietic stem cells in bone marrow can be mobilized into peripheral blood by cytokine administration. Cytokine-mobilized peripheral blood stem cells are of great use in clinical applications. We previously established a modified procedure for the collection of cytokine-mobilized peripheral blood cells from rhesus monkeys using a commercially available apparatus originally developed for human subjects. In this study, we examined the efficacy and safety of this method with even smaller macaques, cynomolgus monkeys, which are equivalent to human newborns in body weight (mean = 3.3 kg). Using the manufacturer’s unmodified protocol (n = 6), one monkey died of cardiac failure and three developed severe anemia. In contrast, using our modified procedure (n = 6), no such complication was observed in any animal. In addition, the harvested nuclear cell, mononuclear cell and CD34+ cell counts were significantly higher with the modified method. The modified method should allow safe and efficient collection of cytokine-mobilized peripheral blood cells from non-human primates as small as human newborns in a non-invasive manner.”
* Aerial surveys give new estimates for orangutans in Sabah, Malaysia. Ancrenaz, M., Gimenez, O., Ambu, L., Ancrenaz, K., Andau, P., Goossens, B., Payne, J., Sawang, A., Tuuga, A., & Lackman-Ancrenaz , I. (Kinabatangan Orang-utan Conservation Project, Sandakan, Sabah, Malaysia). PLoS Biology, 2005, 3; <biology.plosjournals.org>.
. . . “Great apes are threatened with extinction, but precise information about the distribution and size of most populations is currently lacking. We conducted orangutan nest counts in the Malaysian state of Sabah (North Borneo), using a combination of ground and helicopter surveys, and provided a way to estimate the current distribution and size of the populations living throughout the entire state. We show that the number of nests detected during aerial surveys is directly related to the estimated true animal density and that a helicopter is an efficient tool to provide robust estimates of orangutan numbers. Our results reveal that with a total estimated population size of about 11,000 individuals, Sabah is one of the main strongholds for orangutans in North Borneo. More than 60% of orangutans living in the state occur outside protected areas, in production forests that have been through several rounds of logging extraction and are still exploited for timber. The role of exploited forests clearly merits further investigation for orangutan conservation in Sabah.”
* Comparative studies with six extenders for sperm cryopreservation in the cynomolgus monkey (Macaca fascicularis) and rhesus monkey (Macaca mulatta). Li, Y., Cai, K., Li, J., Dinnyes, A., & Ji, W. (W. J., Kunming Inst. of Zoology, Chinese Acad. of Sci., 32 Jiaochang Donglu, Kunming, Yunnan 650223, People’s Republic of China [e-mail: firstname.lastname@example.org]). American Journal of Primatology, 2006, 68, 39-49.
. . . Ejaculated spermatozoa from cynomolgus monkeys and rhesus monkeys were frozen in straws with six different extenders (TTE, DM, mDM, LG-DM, G-DM, and TCG) containing glycerol. Sperm motility and head membrane and acrosomal integrity were evaluated after freezing and thawing, and the cryoprotective effects were compared among the extenders and the two species studied. The results showed that sperm motility and motility recovery with the six extenders were comparable for the cynomolgus and rhesus monkeys. There was no significant difference in sperm motility and head membrane integrity among the six extenders in either the cynomolgus or rhesus monkeys (P>0.05). However, a slightly but statistically lower percentage of acrosomal integrity was found with TCG in both species compared to the other extenders (P<0.05). These findings demonstrate that TTE, DM, mDM, LG-DM, G-DM, and TCG are equally suitable extenders for the cryopreservation of spermatozoa from cynomolgus and rhesus monkeys.
* Effect of sugar type on the survival of frozen-thawed rhesus monkey (Macaca mulatta) sperm. Si, W., Wang, H., Reid, C., Hildebrandt, T. B., &L Ji, W. (W. J., address same as above). American Journal of Primatology, 2006, 68, 103-108.
. . . “Sperm-freezing extenders supplemented with sugar or a combination of different sugars are widely used for the cryopreservation of nonhuman primate spermatozoa. Understanding which sugar or combination of sugars offers the highest level of cryoprotection would be beneficial for the development of sperm-freezing extenders. In the present study we aimed to investigate the effect of glucose, lactose, and raffinose separately or in combination on the cryosurvival of rhesus monkey spermatozoa. Toward that end, we prepared eight extenders by adding various types of sugars to a basic medium (BM): G-BM (0.3 M glucose), L-BM (0.3 M lactose), R-BM (0.3 M raffinose), LG-BM (0.15 M lactose+0.15 M glucose), RG-BM (0.15 M raffinose+0.15 M glucose), LR-BM (0.15 M lactose+0.15 M raffinose), and LRG-BM (0.1 M lactose+0.1 M raffinsoe+0.1 M glucose). A saline control (0.157 M sodium chloride) was also used. The results showed no significant difference in post-thaw motility when spermatozoa were frozen with G-BM, L-BM, LG-BM, RG-BM, and LRG-BM, but the post-thaw motility was significantly lower when it was frozen with R-BM, LR-BM, and the saline control. The highest plasma membrane integrity was achieved when spermatozoa were frozen with G-BM, L-BM, LG-BM, RG-BM, and LRG-BM, and the highest acrosome integrity was achieved with G-BM, L-BM, LG-BM, RG-BM, LRG-BM, and the saline control. The results indicate that the various sugars offered different protective effects. For the cryopreservation of rhesus monkey spermatozoa, glucose (monosaccharide) and lactose (disaccharide) were shown to be more suitable than raffinose (trisaccharide) for preserving spermatozoal motility, plasma membrane, and acrosome. Specifically, raffinose was detrimental to sperm acrosome integrity.”
* Microsatellite markers for standardized genetic management of captive colonies of rhesus macaques (Macaca mulatta). Kanthaswamyi, S., von Dollen, A., Kurushima, J. D., Alminas, O., Rogers, J., Ferguson, B., Lerche, N. W., Allen, P. C., & Smith, D. G. (Primate Population Genetics Unit, Veterinary Genetics Laboratory, Univ. of California, Davis, CA 95616 [e-mail: email@example.com]). American Journal of Primatology, 2006, 68, 73-95.
. . . “To preserve genetic variability and minimize genetic subdivision among captive Macaca mulatta at each of the U.S. National Institutes of Health-sponsored regional research colonies, the genetic structure of each colony must be characterized. To compare population genetic and demographic parameters across colonies and generations, one standard panel of highly informative genetic markers is required. We assembled a core marker set of four multiplex polymerase chain reaction (PCR) panels comprising 15 autosomal short tandem repeat (STR) loci with high information content selected from existing panels of well-characterized markers that are currently used for parentage assessment and genetic management of rhesus macaques. We then assessed the effectiveness of these loci for providing high probabilities of individual identification and parentage resolution, and for estimating population genetic parameters that are useful for genetic management.”
* Mate guarding and paternity in mandrills: Factors influencing alpha male monopoly. Setchell, J. M., Charpentier, M., & Wickings, E. J. (Dept of Biological Anthropology, University of Cambridge, U.K. [e-mail: firstname.lastname@example.org]). Animal Behaviour, 2005, 70, 1105-1120.
. . . “We used long-term data on mate guarding and paternity in mandrills, Mandrillus sphinx, (1) to examine cycle day and cycle selection by males; (2) to examine associations between male rank, periovulatory mate guarding and paternity outcome; (3) to test the predictions of the priority-of-access model; and (4) to investigate factors influencing the ability of alpha males to monopolize females. Males mate-guarded on periovulatory days more than on other receptive days, and during conceptive cycles more than during nonconceptive cycles. Both periovulatory mate guarding and paternity outcome correlated significantly with male rank. Alpha males accounted for 94% of periovulatory mate guarding and 69% of paternity, confirming the existence of extremely high reproductive skew in this highly sexually dimorphic species. The fit of the observed distributions of mate guarding and paternity to predictions from the priority-of-access model was good, but in both cases the alpha males accounted for a greater proportion of reproduction than predicted. Mate guarding was a good predictor of paternity, but consistently overestimated the reproductive success of the alpha male. Splitting data into group-years revealed that the percentage of mate guarding by the alpha male decreased with increasing numbers of adult males, and the percentage of paternity decreased with increasing numbers of reproductive males (all postpubertal males). Furthermore, mate guarding became less effective as the number of reproductive males increased. We attribute this to the fact that only males aged 8 years or more mate-guarded, but that all males aged at least 3.8 years may sneak copulations, reducing the effectiveness of mate guarding and therefore reducing paternity concentration in the alpha male.”
