Bennett, A. J., Perkins, C. M., Tenpas, P. D. et al. 2016. Moving evidence into practice: Cost analysis and assessment of Macaques' sustained behavioral engagement with videogames and foraging devices. American Journal of Primatology 78(12)

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...

Dettmer, A. M., Rosenberg, K., Menard, M. T. et al. 2017. 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...

Kroeker, R., Lee, G. H., Bellanca, R. U. et al. 2017. Prior facility affects alopecia in adulthood for rhesus macaques. American Journal of Primatology 79(1), e22551.

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...

Novak, M. A., Menard, M. T., El-Mallah, S. N. et al. 2017. Assessing significant (>30%) alopecia as a possible biomarker for stress in captive rhesus monkeys (Macaca mulatta). American Journal of Primatology 79(1), e22547.

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...

Worlein, J. M.,Kroeker, R., Lee, G. H. et al. 2017. Socialization in pigtailed macaques (Macaca nemestrina). American Journal of Primatology 79(1), e22556.

In response to new emphasis by regulatory agencies regarding socialization, behavioral management programs are allocating greater resources to maximize socialization opportunities for laboratory primates. Information regarding predictors of compatibility and risk of injury for all...

Capitanio, J. P., Blozis, S. A., Snarr, J. et al. 2017. Do “birds of a feather ?ock together” or do “opposites attract”? Behavioral responses and temperament predict success in pairings of rhesus monkeys in a laboratory setting.

The growing recognition that social needs of primates in captivity must be addressed can present challenges to staff at primate facilities charged with implementing pair‐housing solutions for animals. Unfortunately, there are few published papers that...

Hannibal, D. L., Bliss-Moreau, E., Vandeleest, J. et al. 2017. Laboratory rhesus macaque social housing and social changes: Implications for research. American Journal of Primatology 79(1), e22528.

Macaque species, specifically rhesus (Macaca mulatta), are the most common nonhuman primates (NHPs) used in biomedical research due to their suitability as a model of high priority diseases (e.g., HIV, obesity, cognitive aging), cost effective...

Truelove, M. A., Martin, A. L., Perlman, J. E. et al. 2017. Pair housing of macaques: A review of partner selection, introduction techniques, monitoring for compatibility, and methods for long-term maintenance of pairs.

Pair housing of macaques has become a widely implemented compromise between meeting the social needs of the monkeys and allowing for their use in biomedical research. While beneficial to the animals, pair housing can provide...

Pomerantz, O., Baker, K. C. 2017. Higher levels of submissive behaviors at the onset of the pairing process of rhesus macaques (Macaca mulatta) are associated with lower risk of wounding following introduction. American

Social housing of rhesus macaques (Macaca mulatta) is considered to be the cornerstone of behavioral management programs in biomedical facilities. However, it also involves the risk of socially inflicted trauma. The ability to avoid such...
