Macaques (especially Macaca mulatta and M. fascicularis) are commonly used in research—most recently in AIDS research. Their coloration includes gray, brown or black fur. They tend to be heavily built and medium to large in stature. Males and females may differ in weight, body size and canine size. (from Nonhuman Primates in Biomedical Research: Biology and Management pp 41) Macaques are native to Asia and Northern Africa, but thousands are housed in research facilities, zoos, wildlife or amusement parks, and are kept as pets in private homes throughout the world.

  • Rhesus Macaque Sequencing
    White Paper for Complete Sequencing of the Rhesus Macaque (Macaca mulatta) Genome Jeffrey Rogers1, Michael Katze 2, Roger Bumgarner2, Richard A. Gibbs 3 and George M. Weinstock3 I. Introduction Humans are members of the Order Primates and our closest evolutionary relatives are other primate species. This makes primate models of human disease particularly important, as the underlying physiology and metabolism, as well as genomic structure, are more similar to humans than are other mammals. Chimpanzees (Pan troglodytes) are the animals most similar to humans in overall DNA sequence, with interspecies sequence differences of approximately 1- 1.5% (Stewart and Disotell 1998, Page and Goodman 2001). The other apes, including gorillas and orangutans are nearly as similar to humans. The animals next most closely related to humans are Old World monkeys, superfamily Cercopithecoidea. This group includes the common laboratory species of rhesus macaque (Macaca mulatta), baboon (Papio hamadryas), pig-tailed macaque (Macaca nemestrina) and African green monkey (Chlorocebus aethiops). The human evolutionary lineage separated from the ancestors of chimpanzees about 6-7 million years ago (MYA), while the human/ape lineage diverged from Old World monkeys about 25 MYA (Stewart and Disotell 1998), and from another important primate group, the New World monkeys, more than 35-40 MYA. In comparison, humans diverged from mice and other non- primate mammals about 65-85 MYA (Kumar and Hedges 1998, Eizirik et al 2001). In the evaluation of primate candidates for genome sequencing there should be more to selection of an organism than evolutionary considerations. The chimpanzee’s status as Closest Relative To Human has earned it an exemption from this consideration.

  • Urban Ecology of the Vervet Monkey Chlorocebus Pygerythrus in Kwazulu-Natal, South Africa ______
    Urban Ecology of the Vervet Monkey Chlorocebus pygerythrus in KwaZulu-Natal, South Africa __________________________________ Lindsay L Patterson A thesis presented in fulfilment of the academic requirements for the degree of Doctorate of Philosophy in Ecological Sciences At the University of KwaZulu-Natal, Pietermaritzburg, South Africa August 2017 ABSTRACT The spread of development globally is extensively modifying habitats and often results in competition for space and resources between humans and wildlife. For the last few decades a central goal of urban ecology research has been to deepen our understanding of how wildlife communities respond to urbanisation. In the KwaZulu-Natal Province of South Africa, urban and rural transformation has reduced and fragmented natural foraging grounds for vervet monkeys Chlorocebus pygerythrus. However, no data on vervet urban landscape use exist. They are regarded as successful urban exploiters, yet little data have been obtained prior to support this. This research investigated aspects of the urban ecology of vervet monkeys in three municipalities of KwaZulu-Natal (KZN), as well as factors that may predict human-monkey conflict. Firstly, through conducting an urban wildlife survey, we were able to assess residents’ attitudes towards, observations of and conflict with vervet monkeys, investigating the potential drivers of intragroup variation in spatial ecology, and identifying predators of birds’ nests. We analysed 602 surveys submitted online and, using ordinal regression models, we ascertained that respondents’ attitudes towards vervets were most influenced by whether or not they had had aggressive interactions with them, by the belief that vervet monkeys pose a health risk and by the presence of bird nests, refuse bins and house raiding on their properties.

Nonhuman primates maintained in captivity have a valuable role in education and research. They are also occasionally used in entertainment. The scope of these activities can range from large, accredited zoos to small “roadside” exhib- its; from national primate research centers to small academic institutions with only a few monkeys; and from movie sets to street performers. Attached to these uses of primates comes an ethical responsibility to provide the animals with an environment that promotes their physical and behavioral health and well-be- ing.

Simple Summary: Social play among immature individuals has been well-documented across a wide range of mammalian species. It represents a substantial part of the daily behavioral repertoire during immature periods, and it is essential for acquiring an appropriate set of motor, cognitive, and social skills. In this study, we found that infant Tibetan macaques (Macaca thibetana) exhibited similar patterns of social play between males and females, juvenile males engaged more aggressive play than juvenile females, and juvenile females engaged more affiliative play than juvenile males.

  • The Japan Monkey Centre Primates Brain Imaging Repository for Comparative Neuroscience: an Archive of Digital Records Including Records for Endangered Species

Results from comparative studies provide information about common features across primates and species-specifc features of neuroanatomy. Investigation of various species of non- human primates is important for understanding such features, but the majority of comparative MRI studies have been based on experimental primates, such as common marmoset, macaques, and chimpanzee. A major obstacle has been the lack of a database that includes non-experimental primates’ brain MRIs. To facilitate scientifc discoveries in the feld of comparative neuroanatomy and brain evolution, we launched a collaborative project to develop an open-resource repository of non-human primate brain images obtained using ex vivo MRI. As an initial open resource, here we release a collection of structural MRI and difusion tensor images obtained from 12 species: pygmy marmoset, owl monkey, white-fronted capuchin, crab-eating macaque, Japanese macaque, bonnet macaque, toque macaque, Sykes’ monkey, red-tailed monkey, Schmidt’s guenon, de Brazza’s guenon, and lar gibbon.

  • Ranging Bonnet Macaques, Macaca Radiata
    Flexibility in Food Extraction Techniques in Urban Free- Ranging Bonnet Macaques, Macaca radiata Madhur Mangalam1, Mewa Singh1,2* 1 Biopsychology Laboratory, University of Mysore, Mysore, India, 2 Evolutionary & Organismal Biology Unit, Jawaharlal Nehru Centre for Advanced Scientific Research, Bangalore, India Abstract Non-human primate populations, other than responding appropriately to naturally occurring challenges, also need to cope with anthropogenic factors such as environmental pollution, resource depletion, and habitat destruction. Populations and individuals are likely to show considerable variations in food extraction abilities, with some populations and individuals more efficient than others at exploiting a set of resources. In this study, we examined among urban free-ranging bonnet macaques, Macaca radiata (a) local differences in food extraction abilities, (b) between-individual variation and within-individual consistency in problem-solving success and the underlying problem-solving characteristics, and (c) behavioral patterns associated with higher efficiency in food extraction. When presented with novel food extraction tasks, the urban macaques having more frequent exposure to novel physical objects in their surroundings, extracted food material from PET bottles and also solved another food extraction task (i.e., extracting an orange from a wire mesh box), more often than those living under more natural conditions. Adults solved the tasks more frequently than juveniles, and females more frequently than males. Both solution-technique and problem-solving characteristics varied across individuals but remained consistent within each individual across the successive presentations of PET bottles. The macaques that solved the tasks showed lesser within-individual variation in their food extraction behavior as compared to those that failed to solve the tasks.

However, assessing dominance hierarchy can be a time-consuming activity which 15 is potentially impeded by environmental factors, difficulties in the recognition of animals, or 16 through the disturbance of animals during data collection. Here we took advantage of novel 17 devices, Machines for Automated Learning and Testing (MALT), designed primarily to study 18 nonhuman primates’ cognition - to additionally measure the social structure of a primate group. 19 When working on a MALT, an animal can be replaced by another; which could reflect an 20 asymmetric dominance relationship (or could happen by chance). To assess the reliability of our 21 automated method, we analysed a sample of the automated conflicts with video scoring and found 22 that 75% of these replacements include genuine forms of social displacements.

  • High-Ranking Geladas Protect and Comfort Others After Conflicts
    www.nature.com/scientificreports OPEN High-Ranking Geladas Protect and Comfort Others After Conficts Elisabetta Palagi1, Alessia Leone1, Elisa Demuru1 & Pier Francesco Ferrari2 Post-confict afliation is a mechanism favored by natural selection to manage conficts in animal Received: 2 January 2018 groups thus avoiding group disruption. Triadic afliation towards the victim can reduce the likelihood Accepted: 30 August 2018 of redirection (benefts to third-parties) and protect and provide comfort to the victim by reducing its Published: xx xx xxxx post-confict anxiety (benefts to victims). Here, we test specifc hypotheses on the potential functions of triadic afliation in Theropithecus gelada, a primate species living in complex multi-level societies. Our results show that higher-ranking geladas provided more spontaneous triadic afliation than lower- ranking subjects and that these contacts signifcantly reduced the likelihood of further aggression on the victim. Spontaneous triadic afliation signifcantly reduced the victim’s anxiety (measured by scratching), although it was not biased towards kin or friends. In conclusion, triadic afliation in geladas seems to be a strategy available to high-ranking subjects to reduce the social tension generated by a confict. Although this interpretation is the most parsimonious one, it cannot be totally excluded that third parties could also be afected by the negative emotional state of the victim thus increasing a third party’s motivation to provide comfort. Therefore, the debate on the linkage between third-party afliation and emotional contagion in monkeys remains to be resolved. Conficts in social animals can have various immediate and long-term outcomes. Immediately following a con- fict, opponents may show a wide range of responses, from tolerance and avoidance of open confict, to aggres- sion1.
