Activity of the hypothalamic-pituitary-adrenal axis is altered by aging and exposure to social stress in female rhesus monkeys

The effects of age on the response to two doses of dexamethasone and two doses of CRF were assessed in females living in a stable social environment (control) and in socially stressed females removed from their group and housed temporarily...

Environmental enrichment for rhesus macaques: A cost-effective exercise cage

A movable exercise cage for rhesus macaques is described. Within our facility, increased visual attentiveness by other animals, decreased self-directed biting and hair picking, and improved food consumption was observed when rhesus macaques were permitted access to an exercise cage...

Social awareness in monkeys

Tests of self-awareness in nonhuman primates have to date been concerned almost entirely with the recognition of an animal's reflection in a mirror. By contrast, we know much less about non-human primates' perception of their place within a social network,...

The lower-row cage may be dark, but behavior does not appear to be affected

The situation of 3 upper-row single-caged females was compared with that of 6 lower-row single-caged females. Mean light levels at nine different positions within the cage were significantly lower in bottom-row cages than in upper-row cages. Not only did light...

A comparison of cell-mediated immune responses in rhesus macaques housed singly, in pairs, or in groups

The data demonstrate that social housing condition affects immune responses. While not unidirectional, these effects generally suggest enhanced immune responses for socially housed animals. .... It is our contention that strong social relationships, particularly the affiliative interactions that characterize our...

A few new developments in primate housing and husbandry

A major focus of this paper is an examination of the complementary role that behavioral management strategies play in the establishment and enhancement of well-defined nonhuman primate research resources. .... Additionally, I will discuss the use of positive reinforcement training...

Blood collection procedure of laboratory primates: A neglected variable in biomedical research

A survey of 75 biomedical articles dealing with stress-dependent blood parameters in caged primates revealed that the conditions under which blood collection occurred were in most cases [72%] described either not at all or so haphazardly that it would be...

Meeting the social space requirements of pair-housed primates

Social space is the space required by a subordinate partner to buffer potential social tension, by increasing the distance to a dominant counterpart. At a minimum, pair-housed animals should be allocated at least twice the cage space that is legally...
