Assessing significant (>30%) alopecia as a possible biomarker for stress in captive rhesus monkeys (Macaca mulatta)

Hair loss is common in macaque colonies. Very little is known about the relationship between psychological stress and hair loss. We initially examined alopecia and hair cortisol concentrations in 198 (89 male) rhesus macaques from three primate centers and demonstrated...

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...

Moving evidence into practice: Cost analysis and assessment of Macaques’ sustained behavioral engagement with videogames and foraging devices

Environmental enrichment plans for captive nonhuman primates often include provision of foraging devices. The rationale for using foraging devices is to promote species‐typical activity patterns that encourage physical engagement and provide multi‐sensory stimulation. However, these devices have been shown to...

Biobehavioral consequences of prenatal exposure to a matrilineal overthrow and relocation in captive infant rhesus (Macaca mulatta) monkeys

There is a general consensus that perinatal experiences help to shape infant behavior; however, relatively little is known about the effects of prenatal experience on postnatal phenotype in non‐human primates. The current study sought to take advantage of a naturally...

Relocation stress induces short-term fecal cortisol increase in Tonkean macaques (Macaca tonkeana)

The level of glucocorticoids, especially if obtained from noninvasive sampling, can be used as an index of animal well-being, allowing evaluation of the animal's response to environmental modifications. Despite evidence that these hormones play a relevant role in energy metabolism...

Daily travel distances of zoo-housed chimpanzees and gorillas: Implications for welfare assessments and space requirements

The degree to which the relatively smaller area of artificial environments (compared with natural habitats) has measureable effects on the behavior and welfare of captive animals has been debated for many years. While there is little question that these spaces...

A new method of walking rehabilitation using cognitive tasks in an adult chimpanzee (Pan troglodytes) with a disability: A case study

There are few studies of long-term care and rehabilitation of animals which acquired physical disabilities in captivity, despite their importance for welfare. An adult male chimpanzee named Reo at the Primate Research Institute of Kyoto University, developed acute myelitis, inflammation...

Fecal glucocorticoid metabolite responses to management stressors and social change in four species of callitrichine monkeys

The use of enzyme immunoassays (EIA) for the non-invasive measurement of glucocorticoids provides a valuable tool for monitoring health and welfare in sensitive species. We validated methods for measuring fecal glucocorticoid metabolites (FGM) using the response to veterinary exams for...
