Effect of increased space on behaviors of captive chimpanzees

The results suggest that increased space may reduce some social interactions. It is not clear if levels of social activity [in general] in smaller spaces are 'abnormally' high, and are reduced to more 'normal' levels following an increase in available...

Mirrors as enrichment for captive chimpanzees (Pan troglodytes)

When the mirror gave subjects visual access to neighboring animals, sexual and agonistic behaviors increased, whereas play behavior decreased compared with when no mirror was present.

A canine companion for a nursery-reared infant chimpanzee

Reduction in rocking and other stress-related behaviors in the dog's presence is a strong argument for providing nursery-reared chimpanzees with dog companions. ... We have safely housed dogs with single infants as well as with small groups of infants, until...
