Hanniba, D., Beisner, B., Nathman, A. et al. 2018. Removals based on low within-matriline relatedness can reduce severe aggress

Previous observational research of captive rhesus macaques suggests that higher coefficients of relatedness within matrilines are associated with lower rates of severe within‐matriline aggression and more cohesive grooming communities. We tested whether experimental removals targeted...

Heagerty, A. L., Coleman, K. 2018. Amount and reciprocity of affiliative behaviors can predict pairing success in captive

Socialization is one of the most important forms of enrichment for rhesus macaques. However, pair introductions can result in aggression and injury if partners are incompatible, even days after the initial introduction. Identifying predictors of...

Bloomsmith, M. A., Lambeth, S., Lutz, C. et al. 2018. Welfare measures for laboratory chimpanzees in the United States. America

Behavioral assessment is an essential element of chimpanzee care. Behavioral data were compiled from four chimpanzee laboratory facilities (N = 522; 286 females, 236 males) using differing methods of assessment including quantitative data collection, animal...

Laszlo, K., Morin, L., Veeder, C. L. 2018. Predictors of pair housing success vary in captive St. Kitts African green monkeys

Though African Green Monkeys (AGMs), or vervets, are widely used in research, little is known in regards to their successful pair housing. Due to difficulties with long‐term successful social housing of same‐sex pairs, we attempted...

Neal Webb, S. J., Hau, J., Schapiro, S. J. 2018. A comparison of activity patterns of captive chimpanzees (Pan troglodytes) hou

Primadomes™ and corrals, two types of housing options available to captive chimpanzees, differ in several physical features, including closed (primadomes™) or open (corrals) tops, mesh (primadomes™) or concrete (corrals) walls, and available space per animal...

Crast, J., Seelig, D., Meeker, T. L. et al. 2018. Rhesus monkey (Macaca mulatta) groups with more non-natal adult males p

Limiting contact aggression and social stress is a principal animal welfare challenge in managing large groups of captive nonhuman primates. This challenge is especially pronounced in rhesus monkeys (macaca mulatta), a species characterized by a...

Pierre, P. J., Sullivan, J., Rosga, M. et al. 2018. Long term behavioral and clinical outcomes for nursery reared macaques. A

Nursery rearing (NR) as an experimental manipulation has informed our understanding of the basic bio‐behavioral mechanisms of development. Nursery rearing also occurs for clinical support of infants that fail to thrive or are rejected by...

Bloomsmith, M. A., Truelove, M. A., Cowan‐Brown, J. et al. 2018. Comparing abnormal and fear-related behaviour under t

Two nursery rearing strategies for infant rhesus macaques (Macaca mulatta) were compared to measure effects on abnormal and fear‐related behavior. Changes made from the standard nursery‐rearing procedures (SN) included earlier exposure to peers, frequent peer‐group...

Coleman, K., Robertson, N. D. 2018. Training non-lactating rhesus macaques to act as foster mothers. American Journal o

There can be psychological and physiological consequences resulting from nursery rearing rhesus macaques. To reduce the need for nursery rearing, orphaned infants are often placed with lactating foster mothers. Unfortunately, a supply of these lactating...
