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...

A rational approach to enriched nutrition for nonhuman primates

Obesity is a concern with nonhuman primates (NHPs) housed in captivity for extended periods of time, mostly due to overfeeding and lack of exercise. This is often compounded by environmental enrichment programs that include different types of food. That is...

Space use as an indicator of enclosure appropriateness: A novel measure of captive animal welfare

Empirical measures of animal behavior and space use within the captive environment can provide critical information about animals' requirements, preferences and internal states. Chimpanzees showed significant differences in how they used structural elements (P = 0.021), mesh barriers (P =...

Effects of positive reinforcement training techniques on the psychological welfare of zoo-housed chimpanzees (Pan troglodytes)

Captive environments encompass various factors that can elevate stress levels and jeopardize the wellbeing of the captive animals. The use of positive reinforcement training (PRT) techniques enables researchers and caretakers to reduce tension directly associated with potentially stressful procedures and...

Welfare and housing of chimpanzees in captive settings

Advances in facility design, healthcare, and other strategies have produced an excellent quality of life for chimpanzees (Pan troglodytes) in biomedical research. Historically, many facilities housed chimpanzees individually or in small groups (2–3 animals). Laboratory chimpanzees today have interactive environments...
