In research centers that study primates, pairing unfamiliar subjects is the most costly and difficult problem that staff face. Recent studies in adult rhesus macaques suggest that social competence and sociality, as measured by ease...
Animal welfare regulations have required social housing of primates for more than two decades, although many veterinary and scientific exemptions have been approved with oversight by Institutional Animal Care and Use Committees (IACUCs). In recent...
Physiological and psychological effects of listening to music have been documented in humans. The changes in physiology, cognition and brain chemistry and morphology induced by music have been studied in animal models, providing evidence that...
Primates are notable for having a rich and detailed understanding of their social environment and there has been great interest in the evolution and function of social knowledge in primates. Indeed, primates have been shown...
Rhesus macaques in their natural environments, as well as in the free-ranging colony at Cayo Santiago, Puerto Rico are highly seasonal breeders. Many animal species lose breeding seasonality when brought under captive conditions. The present...
Cognitive abilities likely evolved in response to specific environmental and social challenges and are therefore expected to be specialized for the life history of each species. Specialized cognitive abilities may be most readily engaged under...
We are committed to ensuring all our animals have the highest level of care and welfare. To this end, our social housing program includes placing all animals in pairs or groups. We have a rate...
At Charles River Laboratories, we are committed to ensuring all animals have the highest level of care and welfare. To this end, our social housing program includes placing all nonhuman primates in pairs or groups...
Medical care of nonhuman primates in a laboratory setting can be challenging due to the safety concerns inherent in handling conscious animals. A mature, adult male cynomolgus macaque presented with a chronic foot condition that...
Visual barriers have been shown to be valuable environmental components of nonhuman primate housing to break visual contact between conspecifics as well as between primates and their human keepers. The effect of visual barriers can...
