Stereotypic behaviors are common in captive primate colonies, and it would be beneficial to know effective methods of remediation, and which animals are most likely to express the behavior. The first goal of this research...
Captive rhesus macaques sometimes exhibit undesirable abnormal behaviors, such as motor stereotypic behavior (MSB) and self-abuse. Many risk factors for these behaviors have been identified but the list is far from comprehensive, and large individual...
This study addresses a recommendation in The Guide for the Care and Use of Laboratory Animals to provide singly housed nonhuman primates with intermittent access to large, enriched (play) caging. Research on the potential benefits...
Animal training programs are used at many animal facilities to refine human-animal interactions. While there is a strong focus on positive reinforcement training (PRT) over negative reinforcement training (NRT) or punishment, animals vary in responsiveness...
Alopecia is relatively rare in wild primates but more frequent in captive settings. We investigate whether increasing the quantity and variety of produce enrichment reduces alopecia. Alopecia was scored bimonthly from September 2011 through mid-November...
Alopecia in captive macaques is assumed to have a behavioral cause; either by over-grooming, or a result of stress. Analysis of behavioral treatments of alopecia remains elusive, yet facilities are accountable for treatment. Retrospective analysis...
Alopecia is a persistent problem in laboratory macaques, and is important to address due to the perceived implication for health and psychological well-being. Alopecia ratings were taken at 4 time points over a 12-month period...
Environmental enrichment is provided to laboratory-housed nonhuman primates to encourage species-typical behaviors. Some enrichment is labor intensive so quantitative studies should be undertaken to assure that the benefit is worth the effort expended. This study...
Non-human primates occasionally exhibit behaviours thought to occur only in captivity that are considered abnormal. In particular, hair-plucking behaviour occurs across many species of mammals and birds. This study was the first to assess the...
Although alopecia in captive baboons has previously been assessed, the incidence of alopecia in large groups of baboons housed in more expansive outdoor settings has not been evaluated. The purpose of this study was to...
