Reciprocity and interchange of grooming and ?support? in captive chimpanzees

Reciprocity and interchange of grooming and coalition formation of captive chimpanzees, Pan troglodytes, were studied at a group level as (partial) correlations between an actor matrix and a receiver matrix. Periods in which one male clearly occupied the alpha-position and...

Formation of a new social group of unfamiliar female rhesus monkeys affects the immune and pituitary adrenocortical systems

Eight adult females were introduced into an enclosure. Initial dominance rank was established within 48 h by noncontact threats and chases and was unchanged throughout the [9-week] study. Only two minor wounds were recorded. The animals showed stress responses during...

Environmental challenges in groups of capuchins

Small food items, such as seeds and diced vegetables, are regularly strewn in the straw bedding, which provides the monkeys with infinite opportunities to produce change. Each time the bedding is sifted, the configuration of the straw is changed and...

Applied primate ecology: Evaluation of environmental changes to promote psychological well-being

In one [non-referenced] study of longtailed macaques, self-directed aggressive behavior was suppressed (relative to baseline) in the presence of a manipulable object for more than five months, for four out of five animals.

The effects of temporary cover on the behavior of socially housed Stumptailed macaques (Macaca arctoides)

To examine the effects of the provision of temporary cover on the behavior of stumptailed macaques (Macaca arctoides), a single group of 26 animals was observed during 25 testing periods over 7.5 months. During each testing period, the group was...

Use of a grooming and foraging substrate to reduce cage stereotypies in macaques

We examined the effects of a synthetic fleece pad on cage stereotypies in individually housed cynomolgus monkeys. Animals exhibited idiosyncratic repertoires of stereotyped behaviour, including repetitive pacing, swaying circling, bouncing, cage charging, and rocking that occupied on average 11% of...
