Integrating animals into a new group is a challenge for both free-ranging and captive adult male rhesus monkeys (Macaca mulatta), and for females in groups receiving new males. To ensure the genetic viability of the...
Baker, K. C. 2020. Cage position and response to humans in singly-housed rhesus macaques (Macaca mulatta). JAALAS 59(5), 503-507.
Traditional laboratory caging for nonhuman primates is typically configured in a 2-tiered manner, with caging arranged in 2 horizontal rows stacked vertically. Studies of the effects of cage row have yielded inconsistent results with respect...

Video-based markerless motion capture permits quantification of an animal's pose and motion, with a high spatiotemporal resolution in a naturalistic context, and is a powerful tool for analyzing the relationship between the animal's behaviors and...
Rox, A., van Vliet, A. H., Langermans, J. A. M. et al. 2021. A stepwise male introduction procedure to prevent inbreeding in naturalistic macaque breeding groups. Animals 11(2), 545.
Male introductions into captive primate breeding groups can be risky and unsuccessful. However, they are necessary to prevent inbreeding in naturalistic breeding groups. The procedure used to introduce new individuals may affect the success and...
Truelove, M. A., Martin, J. E., Langford, F. M. et al. 2020. The identification of effective welfare indicators for laboratory-housed macaques using a Delphi consultation process. Scientific Reports 10(1), 20402.
Despite the importance for both animal welfare and scientific integrity of effective welfare assessment in non-human primates, there has been little or no consensus as what should be assessed. A Delphi consultation process was undertaken...
Chapa, J. M., Maschat, K., Iwersen, M. et al. 2020. Accelerometer systems as tools for health and welfare assessment in cattle and pigs – A review. Behavioural Processes 181, 104262.
Welfare assessment has traditionally been performed by direct observation by humans, providing information at only selected points in time. Recently, this assessment method has been questioned, as ‘Precision Livestock Farming’ technologies may be able to...

Limiting opportunities for captive nonhuman primates (NHPs) to express species-specific social behaviors may disrupt the adaptive drive for social companionship and may lead to increases in coping behaviors and inactivity. While captive NHPs show improved...
