Post-conflict behaviour of spectacled leaf monkeys (Trachypithecus obscurus)

Studies of postconflict behavior have focused on Old World primates, particularly on members of the cercopithecines and chimpanzees. We present data on patterns of reconciliation in two captive groups of spectacled leaf monkeys, members of the Colobinae. Reconciliation occurred at...

Post-conflict behaviour of wild chimpanzees (Pan troglodytes schweinfurthii) in the Budongo Forest, Uganda

Since de Waal & van Roosmalen (1979) first documented the occurrence of reconciliation between former opponents in captive chimpanzees, the study of the post-conflict behaviour of primates has provided valuable information about some of the details of primate social organisation....

Living conditions affect stress levels of captive chimpanzees

Our results indicate that stress levels in captive chimpanzees are not affected by population density per se (chimpanzees use behavioural coping strategies), but when coupled with high Neighbor Effect stress levels increase. If many groups need to live in close...

Control vs. passive exposure to joystick-controlled computer tasks intended as enrichment for chimpanzees (Pan troglodytes)

This study aimed to test the effects of enhancing control, via joystick-controlled computer games. .. More time spent watching the monitor was associated with more social and lone play and object manipulation, and less inactivity. .. Under mildly stressful conditions,...

Increased cage size affects Aotus time budgets and partner distances

Aotes spp. housed in typical, small, laboratory cages appear to be sedentary animals that spend large amounts of time sitting alone or in physical contact with social partners. ... The Aotus, housed as pairs or family groups, were moved from...
