Includes stereotypies, self-injurious behavior, hair pulling (alopecia), barbering, feather pecking, tail biting, etc.
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...
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...
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...
Alopecia is a common problem in rhesus macaque colonies. A possible cause of this condition is hair-pulling; however the true relationship between hair-pulling and alopecia is unknown. The purpose of this study was to examine...
The influence of several factors on abnormal behaviour was investigated in 46 singly housed sooty mangabeys (Cercocebus atys) (eight nursery-reared, 38 mother-reared), including self-injurious, self-directed, stereotypic locomotion, and faeces/urine-related behaviours (SIB, SDB, SL, FUR, respectively)...
The goal of this project was to evaluate the efficacy of a porch in decreasing feces painting in captive rhesus macaques. The porch is a small extension that is hung on the outside of a...
Alopecia is a persistent problem in captive macaque populations and despite recent interest, no factors have been identified that can unequivocally explain the presence of alopecia in a majority of cases. Seasonal, demographic, and environmental...
