Exhibit use by great apes as part of a post-occupancy evaluation

All apes [6 chimpanzees and 15 gorillas] used the various strata of the exhibits, but there were species differences in exhibit use. Four of the six chimps spent most of their time in the highest two meters of the exhibit,...

Self-biting in caged macaques: Cause, effect and treatment

In the United States, there are an estimated 15,000 individually caged macaques. If 10% of these animals exhibit visible injuries resulting from self-biting and another 10% show unnoticed self-biting behavior, then about 3,000 animals (20%) are affected by this gross...

Environmental Enrichment for Caged Rhesus Macaques (Macaca Mulatta) – Photographic Documentation and Literature Review (Second Edition)

A collection of 108 photos addressing all aspects of environmental enrichment for caged rhesus macaques. Environmental enrichment is the provision of stimuli that promote the expression of species-appropriate behavioral and mental activities in an understimulating environment [p. 1].This collection of...

Training pair-housed rhesus males to cooperate during blood collection

In many laboratory studies, venipuncture (blood collection) is a routine activity. Some animal care managers assume that blood collection requires single-housing and squeezing (and stressing) the primate subjects. Not true!Here, we show a simple training procedure that is based on...

Utilization of training techniques to minimize distress and facilitate the treatment of a chronically ill macaque

In order to permit the more frequent measurement of blood glucose, at times up to eight measurements a day, with minimal or no distress to the animal, we trained the monkey [long-tailed macaque with unspecified gender] to voluntarily present the...

The impossible housing and handling conditions of monkeys in research laboratories

The prevailing housing and handling conditions of monkeys in research institutions is described. The present situation in primate research laboratories strongly suggests that professional judgment is no guarantee that the inhumane housing and handling conditions of laboratory monkeys will ever...

Long-term proximity relationships in a captive social group of western lowland gorillas (Gorilla gorilla gorilla)

To visualize long-term social relationships among 12 gorillas in a captive breeding group at the San Diego Wild Animal Park, San Diego, CA, the multidimensional scaling (MDS) procedure was applied to proximity (within 5 m) values collected in five different...
