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...

Environment- and season-influenced alopecia in juvenile rhesus macaques

The juveniles who were transferred to individual indoor rooms recovered from alopecia and hair growth began withina week. Hence we concluded that hair losses in outside enclosures are due to environmental stress. .. To conclude, if macaques are to be...

Altered hypothalamic-pituitary-adrenocortical function in rhesus monkeys (Macaca mulatta) with self-injurious behavior

These findings suggest that SIB in socially reared monkeys is associated with complex changes in HPA axis function that are related to the expression of the pathology, i.e. self-directed biting, and to the recency of a wounding episode.

Look what’s hanging around! Foraging feeder cup puzzles for cynomolgus macaques

Foraging device is described and demonstrated. It is used by pair-housed cynos to retrieve their daily biscuit ration. No changes in body weights were noticed. No data are included in this article.

Floating limb activity is associated with self-biting in four monkey species (Macaca mulatta, M. fascicularis, M. nemstrina and Papio cynocephalus)

More than 100 monkeys (about 10% of the animals housed at the WaNPRC...) engaged in FLA within the year. Floating limb may be an indicator of a more serious behavioral disorder.

Potential for unintended consequences of environmental enrihment for laboratory animals and research results

Many aspects of the research animal's housing environment are controlled for quality and/or standardization. Of recent interest is the potential for environmental enrichment to have unexpected consequences such as unintended harm to the animal, or the introduction of variability into...
