Ethological studies of well-being in two species of macaques after transition from single cages to housing in social groups

Two species of macaques (M. mulatta and M. fascicularis) have been used for several decades in biomedical research at the University of Uppsala, Sweden. The monkeys were previously housed in single cages and enrichment routines were not ordinarily used. Infants...

Refining the traditional housing and handling of laboratory rhesus macaques improves scientific methodology

A monkey housed in an empty cage, however, is literally a behavioral cripple because s/he is chronically deprived of appropriate stimuli for the expression of species-typical behavior patterns. It is difficult to know objectively if a monkey experiences boredom when...

Abnormal behavior in a captive chimpanzee colony

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 had less abnormal behavior. Access...

The formation of a captive squirrel monkey group

It is important that all females of a new [heterosexual] group are related to each other, that is, that they come from the same natal group. The introduction of unfamiliar females to a small group with several females can result...

Effect of environmental enrichment devices on behaviors of single- and group-housed squirrel monkeys (Saimiri sciureus)

This would suggest that enrichment provided by social interaction ... may play a greater role in maintaining the monkeys' psychological well-being than did physical enrichment devices.

A change in housing condition leads to relatively long-term changes in cell-mediated immune responses in adult rhesus macaques

Changes in the social environment, such as removal and/or reintroduction of groupmates, affect theimmunological responses of captive macaques of all ages. This study compares cell-mediated immuneresponses of adult Macaca mulatta (N= 17) whose housing condition was changed from social to...

A comparison of the effects of simple versus complex environmental enrichment on the behaviour of group-housed, subadult rhesus macaques

Enrichment of the environments of captive primates is currently of interest as both a basic and an applied research question, particularly when social and inanimate enhancements are used simultaneously. We measured the hehavioural effects of two intensities of inanimate enrichment...
