Pair-housing overcomes self-biting behavior in macaques

Subjects exhibited self-biting behavior predictably in the presence of personnel. "The transfer to a compatible social-housing arrangement [isosexual pair-housing] effectively cured the [seven] rhesus subjects from the behavioral pathology of habitual self-biting."

A behavioral comparison of male rhesus macaques (Macaca mulatta) in four different housing conditions

Animals in socially restricted housing [single-housing, single-housing with intermittent social contact] paced significantly more, locomoted significantly less and were more aggressive than subjects housed in groups.

The effect of mother-infant separation in captive baboons on time intervals to first postpartum estrus, confirmed pregnancy and subsequent parturition

It is generally thought that early forced-weaning of infants would reduce the time from parturition to the first fertile postpartum estrus thus maximizing reproductive efficiency. ... From a survey of 23 animal records we determined the following values for mothers...

Videotapes as enrichment for captive chimpanzees (Pan troglodytes)

Individually housed subjects watched the videotapes more than socially housed subjects. When viewing time was averaged across all videotapes, the chimpanzees watched the monitor a mean of 38.4% of the time available. ... Subjects habituated to repeated presentations of the...

Control over videotape enrichment for socially housed chimpanzees

Social behavior and solitary play were higher in subjects with control over the onset of videotapes, while scratching [generally regarded as a sign of tension] was higher in those groups who lacked control. The results indicate that giving chimpanzees control...
