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...

Long-term care of chimpanzees: the role of sanctuaries

Chimpanzees (Pan troglodytes) have served in biomedical and behavioral research since the early 1900s and captive breeding programs to supply chimpanzees have been common since the 1960's. The captive research population reached a peak of approximately 1600 chimpanzees in the...

Successful elimination of self-injurious behavior (SIB) in a chimpanzee (Pan troglodytes): a case study using a combination of risperidone and environmental enrichment

Self-injurious behavior (SIB) can result in open wounds, tissue damage, and increased risk of infection. In many cases, increased environmental enrichment is not consistently effective in eliminating this behavior. We report here on the successful elimination of SIB in a...
