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.

Innovative social behavior in chimpanzees (Pan troglodytes)

We present evidence of agonistic buffering in captive chimpanzees, recorded from 1993 until 2005, mainly from ad libitum sampling in over 2000 hr of observation. A total of 33 agonistic buffering episodes were analyzed for context and effects of this...

Longitudinal comparison of rates of species-typical behavior of chimpanzees (Pan troglodytes) in an enriched laboratory environment

Behavioral observations were conducted as an ongoing program of monitoring psychological well-being of chimpanzees involved in IACUC-approved preventive medicine studies. The chimpanzees were housed in a facility that provided a variety of enrichment objects, climbing structures, and glass-walled enclosures that...
