Pair-housing macaques with biomedical implants: a safe and practical alternative to single-housing

Recognition of the importance of social interaction for primate well-being has led to new USDA guidelines recommending that animal facilities provide social enrichment for captive primates, as long as doing so does not endanger the animals or interfere with research...

Swimming pools provide additional socialization to group-housed male macaques

A group of five subadult male macaques [probably rhesus] adapted easily to a wading pool filled with about 30 cm deep water. The animals swam and dived with eyes open and played in the water.

Flaws in the housing and handling of macaques used for research

Macaques are often caged individually regardless of their social disposition. The National Research Council of the United States admonishes that the common practice of housing rhesus monkeys [the predominant species used in biomedical research] singly calls for special attention. Approximately...

Pair housing adult female rhesus macaques: Is it always the best option?

Cortisol levels between compatible pairs and individually caged animals revealed no significant difference. Cortisol levels had the tendency of being higher (p=0.09) in individually caged animals who had their partner removed for experimental purposes than in individually caged animals who...

Effects of positive reinforcement training on stereotypical behaviour in rhesus macaques

While the sample size it too low to make definitive conclusions, these data suggest that positive reinforcement training may [sic] be useful in reducing the incidence of stereotypic behaviour.

Extinction deficits in male rhesus macaques with a history self-injurious behavior

The presence of extinction deficits suggests that SIB may persist in some monkeys because they lack the ability regulate the intensity of their biting behavior.

Free-ranging infant rhesus monkeys persist in seeking maternal contact and proximity after mothers cease providing substantial levels of nutrition, protection, or transport

Despite this sharp reduction in maternal affordances, 7-10-month-old infants spent more than an average of 25% of their waking time in contact or arms length of their mothers, highly disproportionate to the time they would be expected to spend at...
