Prior facility affects alopecia in adulthood for rhesus macaques

Alopecia has proven to be a persistent problem for captive macaques; many cases continue to elude explanations and effective treatments. Although almost all captive populations exhibit alopecia rates higher than those seen in the wild, there also appear to be...

Differential relationships between chronic hormone profiles in pregnancy and maternal investment in rhesus monkey mothers with hair loss in the neonatal period

Hair loss is commonly used as an indicator of well being in primate facilities, yet it has been shown to also occur in otherwise healthy pregnant and postpartum females. There is significant variability in the incidence of hair loss during...

The primatologist as a behavioral engineer

The field of primate behavior management has had only limited success in preventing and treating abnormal behaviors, such as stereotypy and self‐injury, in captive non‐human primates (NHP). In contrast, applied behavior analysts have had great success in treating similar topographies...

Prevalence and characteristics of hair plucking in captive bonobos (Pan paniscus) in North American zoos

When primates exhibit hair loss and are observed to engage in self or social hair plucking (a rapid jerking away of the hair shaft and follicle by the hand or mouth, often accompanied by inspection, and consumption) the altered appearance,...

Social hair pulling in captive rhesus macaques (Macaca mulatta)

Alopecia is common among captive populations of nonhuman primates. There are many potential causes of alopecia, including physiological conditions such as hormonal imbalance and infection, features of the captive environment such as housing type, ground substrate, and group density, as...

Assessment of environmental enrichment for different primate species under low budget: A case study

The 2011 European Union Zoo Inquiry presented evidence that most zoos fail to achieve adequate levels of nonhuman animal welfare. Appropriate environmental enrichment (EE) can play a role in the promotion of welfare. However, financial and staff constraints frequently make...

Tailored enrichment strategies and stereotypic behavior in captive individually housed macaques (Macaca spp.)

The welfare of nonhuman animals in captivity is widely dependent on the natural psychological, physical, and behavioral needs of the animals and how adequately these needs are met. Inability to engage in natural behaviors can lead to chronic stress and...

Effect of cage-induced stereotypies on measures of affective state and recurrent perseveration in CD-1 and C57BL/6 mice

Stereotypies are abnormal repetitive behaviour patterns that are highly prevalent in laboratory mice and are thought to reflect impaired welfare. Thus, they are associated with impaired behavioural inhibition and may also reflect negative affective states. However, in mice the relationship...

Relationship of thyroid and adrenal function to fur-chewing in the chinchilla

The fur-chewing chinchillas showed increased thyroid activity (P < 0·5), increased adrenalcortical function (P < 0·05) and decreased rectal temperature (P < 0·01). This study suggested that increased endocrine activity could be due to the loss of insulation over the...
