Effect of a preferred companion in modulating stress in adult female rhesus monkeys

Adult female rhesus monkeys exhibited a profound stress response when removed from their social group to a novel environment. Recovery time [of T cell subsets] was significantly enhanced by the presence of a preferred companion.

Psychological well-being in paired adult female rhesus (Macaca mulatta)

Pair formation technique is described; 86% success rate. Paired females show strong preference to spend time in close proximity [approximately 80% at night, 40% at day]; agonistic behaviors are very infrequent. Health measures, body weight gains, reproduction and immune responses...

Space use and proximity of captive chimpanzees (Pan troglodytes) mother/offspring pairs

Results confirmed the importance of vertical cage dimension and suggested the provision of horizontal substrates above the enclosure floor is important.

A grass foraging device for captive chimpanzees (Pan troglodytes)

In the wild, chimpanzees spend most of their time foraging, so any device that stimulates this behaviour in captivity could potentially be effective enrichment. A simple grass foraging device constructed of a polyvinyl chloride (PVC) pipe cut in half lengthwise...

Removal of a trauma-inflicting alpha matriline from a group of rhesus macaques to control severe wounding

Results identify an unusual outbreak of serious wounding by the alpha matriline of a large captive group [of rhesus macaques] and indicate that identification and removal of the animals responsible can be an effective management procedure for controlling such injuries.

Recycled plastic cages and environmental enrichment devices

Although the production and use of recycled plastic lumber is still in its infancy, our experience indicates that this is an ideal material for the construction of environmental enrichment devices for monkeys ... especially in outdoor facilities and zoological collections.
