The UFAW Handbook on the Care and Management of Laboratory Animals (7th ed): Squirrel Monkeys

General husbandry recommendations for squirrel monkeys. The most common form of stereotypic behavior in squirrel monkeys is an exaggerated head twirling, usually associated with pacing. ... The incidence of the behaviour seems to be more frequent in small cages, and...

Assessing the value of television as environmental enrichment for individually housed rhesus monkeys: A behavioral economic approach

The goal of this study was to evaluate television as a source of environmental enrichment for individually housed rhesus monkeys (Macaca mulatta) by using the concepts of behavioral economics. Phase I entailed the use of operant conditioning to assess the...

Changes in nearest-neighbor association in a captive group of Western Lowland gorillas after the introduction of five hand-reared infants

The integration of five hand-reared infants into a group of 5 females and 1 male was successful and without incident. Findings lend strong support to the importance of peer groups and the presence of a silverback male for facilitating the...

The use of guanfacine to control self-injurious behavior in nonhuman primates

Self-injurious behavior (SIB) affects up to 10% of laboratory-housed nonhuman primates. ... Guanfacine therapy provides an effective psychological-stabilizing tool which alleviates self-biting, and provides time to assess and address external stressors and triggers.

Separation induced changes in squirrel monkey hypothalamic-pituitary-adrenal physiology resemble aspects of hypercortisolism in humans

When separated from groups, squirrel monkeys respond with significant increases in plasma cortisol and adrenocorticotropic hormone.

Techniques for collecting saliva from awake, unrestrained, adult monkeys for cortisol assay

Our laboratory has developed two methods [not outlined in this abstract] for collecting saliva [e.g., for cortisol determination] from adult rhesus monkeys: a 'screen' method, which involves licking screen-covered gauze, and a 'pole' method, which involves sucking and chewing on...

Environmental enrichment: Evaluation of the behavioural modifications in the presence of four kinds of litter in Cebus capucinus

A captive group of white-faced capuchins, Cebus capucinus, was presented with four deep litters in simultaneous choice (or preference) tests. A floor covering of ground corn cob, woodchips, wood wool or peat was presented once in each quarter of the...

A review of nutritional and motivational factors contributing to the performance of regurgitation and reingestion in captive lowland gorillas (Gorilla gorilla gorilla)

Regurgitation and reingestion (R/R) is a common phenomenon in captive lowland gorillas (Gorilla gorilla gorilla), but it has never been reported in wild populations. Although changes in diet have been shown to reduce the behavior, little is known about the...
