Male animals of many species use conspicuous coloration to attract mates. Among mammals, primates possess the most brilliant secondary sexual coloration. However, whether colour plays a part in primate female mate choice remains unknown. Adult male rhesus macaques undergo a hormonally regulated increased reddening of facial and anogenital skin during their(More)
There is considerable interest in the study of stress and aggression in primates as a model for their interpretation in humans. Despite methodological and interpretational problems associated with behavioural and physiological measurement and definition, a considerable body of literature exists on these phenomena in primates. In the course of reviewing this(More)
There is considerable evidence that primates housed under impoverished conditions develop behavioural abnormalities, including, in the most extreme example, self-harming behaviour. This has implications for all contexts in which primates are maintained in captivity from laboratories to zoos since by compromising the animals' psychological well-being and(More)
Many captive animals show forms of pelage loss that are absent in wild or free-living conspecifics, which result from grooming or plucking behaviours directed at themselves or at other individuals. For instance, dorsal hair loss in primates such as rhesus macaques (Macaca mulatta) in research facilities, results from excessive hair-pulling or over-grooming(More)
Combining a range of assessment parameters into one usable entity has been identified as an important goal in providing a practical, objective and robust assessment of welfare, particularly in laboratory animals. This paper refines and extends one such previously published method. The proposed Extended Welfare Assessment Grid provides for the incorporation(More)
More long-tailed macaques (Macaca fascicularis) than any other primate are imported into the UK for research, and journey times may be of up to 58 h. Whilst a number of studies have examined the stress associated with transport, these have typically involved laboratory rodents and livestock, and little is known of its effect on non-human primates. This(More)
Introduction When designing a captive environment, the age of the animals concerned should a primary consideration as the requirements of captive primates vary across their lifespans. Primates have long natural lifespans, which are often extended by life in captivity. Many monkey species in captivity (e.g., macaques, capuchins) can have lifespans well over(More)
