Murphy, A. M., Ross, C. N., Bliss‐Moreau, E. 2019. Noninvasive cardiac psychophysiology as a tool for translational science with marmosets. American Journal of Primatology 81(9), e23037.

The importance of marmosets for comparative and translational science has grown in recent years because of their relatively rapid development, birth cohorts of twins, family social structure, and genetic tractability. Despite this, they remain understudied...

Berg, M. R., Heagerty, A., Coleman, K. 2019. Oxytocin and pair compatibility in adult male rhesus macaques (Macaca mulatta). American Journal of Primatology 81(8), e23031.

Pair housing is considered one of the best ways of promoting psychological wellbeing for caged macaques. However, incompatible partnerships can result in stress or aggression. Though previous studies have analyzed the role of variables such...

Hopper, L. M., Fernandez‐Duque, E., Williams, L. E. 2019. Testing the weekend effect hypothesis: Time of day and lunar phase better predict the timing of births in laboratory‐housed primates than day of week. American Journal of Pri

The weekend effect hypothesis proposes that captive primates are more likely to give birth during times of low disturbance and reduced staff activity. The hypothesis specifically predicts that laboratory‐housed primates will be more likely to...

Sterck, E. H. M., Zijlmans, D. G. M., de Vries, H., et al. 2019. Determining overweight and underweight with a new weight‐for‐height index in captive group‐housed macaques. American Journal of Primatology 81(6), e22996.

Housing primates in naturalistic groups provides social benefits relative to solitary housing. However, food intake may vary across individuals, possibly resulting in overweight and underweight individuals. Information on relative adiposity (the amount of fat tissue...

Howell, C. P., Cheyne, S. M. 2019. Complexities of using wild versus captive activity budget comparisons for assessing captive primate welfare. Journal of Applied Animal Welfare Science 22(1), 78-96.

Activity budget comparisons between groups or individuals in the wild and those in captivity are commonly used to determine the range of wild-type behaviors that nonhuman animals in captivity perform. These comparisons are conducted with...

Beisner, B. A., Wooddell, L. J., Hannibal, D. L. et al. 2019. High rates of aggression do not predict rates of trauma in captive groups of macaques. Applied Animal Behaviour Science 212, 82-89.

Socially inflicted traumas are a major concern for the management of captive groups of rhesus macaques. Rhesus macaques are the most commonly used nonhuman primate in biomedical research, and social housing is optimal for promoting...

Jacobson, S. L., Kwiatt, A. C., Ross, S. R. et al. 2019. The effects of cognitive testing on the welfare of zoo-housed Japanese macaques (Macaca fuscata). Applied Animal Behaviour Science 212, 90-97.

Cognitive testing programs are being implemented more frequently in zoo settings due to the benefits these programs can provide for the animals, researchers and zoo visitors. However, the impact that cognitive studies have on the...

Rox, A., de Vries, H., Louwerse, A. L. et al. 2018. Female social behaviour during three male introductions in captive groups of rhesus macaques. Applied Animal Behaviour Science 207, 89-97.

Introductions of new males into captive primate groups are often necessary to prevent inbreeding, but also bear high social risks. To minimize these risks, it is crucial to understand the social behaviour accompanying male introductions...
