Macaque

Differences in stress reactivity of laboratory macaques measured by heart period and respiratory sinus arrhythmia

Exposure to an unfamiliar technician with capture gloves stimulated cardiac reactivity more strongly than an intense sound. ... Behavior responses to the glove indicated that all subjects consistently perceived this 'ecologically relevant' stimulus as threatening.

Evaluation of stainless steel reflective discs as enrichment devices for rhesus monkeys (Macaca mulatta) housed in a toxicological facility

The enrichment device was used [probably by single-caged subjects] primarily for manipulation and banging. ... The usage of polished stainless steel discs declines over time and therefore alternative methods of environmental enrichment and rotation of enrichment devices should be considered.

Food and feeding behaviour of the pig-tailed macaque (Macaca nemestrina leonina) in semi-evergreen forest in Bangladesh

This subspecies is completely arboreal and frugivorous. The group spent 21.7% of their daily active time on feeding and 39.6% time on foraging.

Psychological well-being of captive nonhuman primates

Merely increasing cage size has not been associated with meaningful improvements in psychological well-being among singly housed macaques. Environmental change, such as being moved into a new room, disturbs monkeys, as demonstrated by appetite suppression, disruption of the normal activity...

Social relationships in a newly established all-male group of lion-tailed macaques (Macaca silenus)

Observations covered the first nine weeks [after group formation]. The males interacted rarely. In 8 of 15 dyads grooming occurred. Aggressive behaviour normally occurred without physical contact. ... The males showed a tendency to use the same or adjacent rooms...

Effects of puzzle feeders on pathological behavior in individually housed rhesus monkeys

Self-injurious behavior (SIB) occurs in about 10% of individually housed monkeys. Monkeys with SIB bite their own bodies frequently, occasionally inflicting wounds as a result [p. 213] ... Of great concern is the development of a severe from of abnormal...

Practical aspects of the program to promote psychological well-being in nonhuman primates at the Oregon Regional Primate Research Center

A comprehensive inanimate and animate enrichment program for rhesus macaques is described and valuable recommendations made to facilitate optimal psychological well-being throughout the animals' lives. A successful (80% compatibility) pair formation protocol for female rhesus macaques is outlined. New pairs...
