Species-specific behaviors

The relationships between captive non-human primates and their caregivers are critical to animals welfare. One method to mitigate the potential negative effects and to promote positive relationships is for caregivers to employ species-specific behaviors in their interaction with their charges....

Note on effects of a daylong feeding enrichment program for Chimpanzees (Pan troglodytes)

This study is designed to determine whether longer feeding opportunities over the course of a day would directly engender longer feeding times. A liquid dispenser was presented for 8 h/day to five chimpanzees. The daily feeding duration was increased to...

Components of an animal training program at a large institution

The application of positive reinforcement training (PRT) has increased in zoological, laboratory, and research settings in recent years, however there is little literature pertaining to the development and implementation of such programs. Over the past year, Yerkes National Primate Research...

Effects of short- and long-term changes in spatial density on the social behavior of captive chimpanzees (Pan troglodytes)

The purpose of this study was to test the conflict-avoidance and tension-reduction models by examining the effects of both short-term (1-2 days) and long-term (6 months) changes in spatial density on social behavior in 23 adult captive chimpanzees (6 males,...

Effects of two types and two genres of music on social behavior in captive chimpanzees (Pan troglodytes)

The purpose of this study was to test the effects of 2 different types (vocal versus instrumental) and 2 genres (classical vocal versus 'easy-listening' vocal) of music on social behavior in 31 female and 26 male chimpanzees (Pan troglodytes). Results...

Rehabilitation of research chimpanzees: Stress and coping after long-term isolation

We report on the permanent retirement of chimpanzees from biomedical research and on resocialization after long-term social isolation. Our aim was to investigate to what extent behavioral and endocrine measures of stress in deprived laboratory chimpanzees can be improved by...

The effect of a new vertical structure in mitigating aggressive behaviour in a large group of chimpanzees (Pan troglodytes)

The proportion of serious injuries was lower in the three years after (32%) than the three years before (59%) the vertical structure was erected.
