Male pigtailed macaques neonatally separated from mothers for clinical reasons show increased abnormal behavior as adults

The proportion of the first 48 months of life spent singly housed was significantly related to abnormal behavior in maturity. It explained 12% of abnormal behavior in mother-reared animals, 42% in experimental-nursery-reared animals, and 55% in clinical-nursery-reared animals.

Training multi-task medical behaviors in the bonobo (Pan paniscus)

The bonobo training program at the Milwaukee County Zoo (MCZ) began in 1993. Currently, the bonobos voluntarily participate in medical behaviors that involve performing several tasks simultaneously. To date, we have compiled three complete sets of obstetrical ultrasound measurements, have...

Effects of olfactory stimulation as environmental enrichment for adult cynomolgus monkeys

[Unspecified] test odours were transferred onto fleece squares. The results of this study suggests that odour is a weak stimulus for environmental enrichment of macaques.

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,...
