Environmental improvements include construction of large indoor cages that allow pairing of experimental animals, a grass-covered 'playground' for breeding chimpanzee groups, and indoor/outdoor group housing for 'retired' experimental animals. In addition, we provide toys, perches...
Published information provides scientific evidence that traditional, involuntary restraint techniques of research non-human primates are intrinsically a source of distress resulting from fear. It has been documented that common methods of enforced restraint result in...
The aquarium [with a single goldfish] was attached to the outside of the chimpanzee's cage ... so that the single-caged subject was able to touch the aquarium but not the fish itself. At the conclusion...
Cage space requirements for non-human primates in the United States of America are less than those in European countries. Studies in support of the assumption that the US legal minimum cage size provides adequate space...
Results suggest a preference for horizontal furnishings above the enclosure floor. Adults infrequently used 'moving' furnishings (e.g., swinging ropes, hanging tubes, etc...) and seemed to prefer 'stable' horizontal furnishings (e.g., benches, logs) above the enclosure...
Brief but very useful guidelines of how an enrichment program can most effectively be developed and implemented. Care and research staff ideas are well-thought out prior to use of any new devices, and all staff...
The purpose of this study is to consider space use patterns of a single group of captive chimpanzees (Pan troglodytes) housed in an indoor exhibit at the Cleveland Metroparks Zoo. This report summarizes results from...
Twenty-six reports provide detailed information of how primates can be trained to voluntarily cooperate - rather than resist - during blood collection, injection, topical drug application, blood pressure measurement, urine collection, and capture.
There is a growing awareness that non-human primates kept in zoos and laboratories deserve more species-appropriate stimulation because of their biological adaptation to a challenging environment. Numerous attempts have been made to effectively emulate the...
The purpose of this study was to link abnormal behaviors often expressed by chimpanzees living in captive environments to factors related to their care and housing. Individuals who had spent more time with their mothers...
