Xenospecific enrichment at the Primate Research Institute

Nursery reared, single-housed and group-housed chimpanzees were exposed to a puppy after careful prior familiarization. ... The complete physical introduction [with single-caged subject] initially resulted in tugs-of-war over toys and blankets. The chimpanzee would alternately grimace, whimper-woo, or initiate play...

Evaluation of a chimpanzee enrichment enclosure

A large, three-part playground for captive chimpanzees was constructed and evaluated in terms of area use and behavior changes. Comparative behavioral samples were obtained on 38 subjects in the existing indoor-outdoor run and in the enclosure. The chimpanzees used the...

Reciprocity and interchange of grooming and ?support? in captive chimpanzees

Reciprocity and interchange of grooming and coalition formation of captive chimpanzees, Pan troglodytes, were studied at a group level as (partial) correlations between an actor matrix and a receiver matrix. Periods in which one male clearly occupied the alpha-position and...
