Nonhuman Primate

Primatology and primate well-being

Rather than fostering a climate of intelligent inquiry and lovely concern, the effect of the proposed rules will be oppressive and inhibitory. They will reduce individual discretion and institutional flexibility in the care of captive primates.

Primate research models and environmental enrichment

An apparatus that the monkey can control, and that responds to the monkey in some way, will be used by a larger proportion of animals, and for a longer period of time, than devices or toys that are not actively...

Uprooted trees facilitate the psychological well-being of captive chimpanzees

Group-housed subjects used the tree during 41.9% of the data points collected during the first day trees were introduced. Thereafter, the mean for trees use dropped to 3.5% and remained fairly consistent.

Food puzzle device simulating termite fishing for captive chimpanzees (Pan troglodytes)

Significant reductions of abnormal behavior and significant increases in activity occurred with the pipe feeder's availability. Species-typical tool-using activity occurred, and the use of the pipe feeder increased subjects' foraging and feeding activity toward more species-normative levels. In the corral-housed...

Influence of cage size on heart rate and behavior in rhesus monkeys

In single-housed subjects there were no significant differences in basal heart rates or activity counts as a function of cage size [of barren, single cages].

Heart rate and activity of rhesus monkeys in response to routine events

Adult female rhesus macaques responded with a significant, protracted increase in heart rate to being placed in transfer boxes while their dirty cages were replaced with clean ones. The mean heart rate remained elevated for two hours after completion of...

Adult female rhesus macaque responses to novel objects

At least half of the [single-housed] subjects used each of the objects presented [plastic ball, ring and block]. The large behavioral variation both within and between monkeys suggests individual preferences for objects, and indicates the need for long-term evaluation on...

Evaluation of attempts to enrich the environment of single-caged non-human primates

A review of early studies of enrichment for single-housed primates. Our experience with cage toys suggests that after a very short time (a few days or less), most macaques will lose interest in the objects that are offered. Rhesus macaques...

How not to enlarge a stable group of stumptailed macaques (Macaca arctoides)

The best advice, based on our experience with established groups of stumptails, is to combine groups, or introduce adult animals, only as a very last resort, and then with great care and assiduous monitoring.

Alternatives to single caging of rhesus monkeys (Macaca mulatta) used in research

Single-housed rhesus macaques were transferred to permanent pair-housing arrangements. The present investigation also demonstrates that pairing caged rhesus monkeys with compatible conspecifics does not interfere with a number of common research protocols [e.g., headcap implantation, experimental surgery, blood collection]. Our...
