Hair loss and hair-pulling in rhesus macaques (Macaca mulatta)

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 relationship between hair loss...

Alopecia in corral-housed baboons: the impact of season, sex, and age

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 evaluate the extent of alopecia...

Alopecia in three macaque species housed in a laboratory environment

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 on all rhesus (N =...

Behavior treatment of alopecia in macaca fascicularis: Comparison of outcomes

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 of effects of treatment type...

Hair loss and hypothalamic-pituitary-adrenocortical axis activity in captive rhesus macaques (Macaca mulatta)

Hair loss is a common problem in captive macaque colonies. A potential factor is the possible influence of stressful environments in the development of hair loss. We examined the relationship between hair loss and chronic hypothalamic-pituitary-adrenal (HPA) axis activity by...

Use of an aquarium as a novel enrichment item for singly housed rhesus macaques (Macaca mulatta)

Locomotor stereotypies are behaviors often seen in singly housed rhesus macaques (Macaca mulatta) and are considered to represent a maladaptive response to captive environments. Active and passive enrichment items are commonly used to mitigate these and other abnormal behaviors. Active...

Abnormal behavior and associated risk factors in captive baboons (Papio hamadryas spp

Abnormal behavior, ranging from motor stereotypies to self‐injurious behavior, has been documented in captive nonhuman primates, with risk factors including nursery rearing, single housing, and veterinary procedures. Much of this research has focused on macaque monkeys; less is known about...

Using porches to decrease feces painting in rhesus macaques (Macaca mulatta)

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 monkey's primary home cage. Porches...

Abnormal behaviour in captive sooty mangabeys

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). An analysis of behavioural assessments...

Stereotypic mice are aggressed by their cage-mates and tend to be poor demonstrators in social learning tasks

Stereotypic behaviours (SBs) are linked with behavioural inflexibility and resemble symptoms of autism, suggesting that stereotypic animals could have autistic-like social impairments. SBs are also common in caged mice. We therefore hypothesised relationships between stereotypic and social behaviours, predicting that...
