Use of introduction enclosures to integrate multimale cohorts into groups of female rhesus macaques (Macaca mulatta)

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 population, however, male transfers must...

It takes a village: A case study in improving animal welfare with a team approach

There are many factors that need to be considered when caring for groups of nonhuman primates (NHPs) in research, including clinical, behavioral, and scientific issues. Otherwise, there is the potential that decisions are made without taking all these needs into...

Cage position and response to humans in singly-housed rhesus macaques (Macaca mulatta)

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 to impacts on psychological well-being....

A stepwise male introduction procedure to prevent inbreeding in naturalistic macaque breeding groups

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 influence the risks associated with...

MacaquePose: A novel “in the wild” macaque monkey pose dataset for markerless motion capture

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 its brain functions. Macaque monkeys...

Using preferred fluids and different reward schedules to motivate rhesus macaques (Macaca mulatta) in cognitive tasks

Rhesus macaques (Macaca mulatta) used in behavioural neuroscience are often required to complete cognitively complex tasks, for which a high level of motivation is essential. To induce motivation, researchers may implement fluid-restriction protocols, whereby freely available water is limited, such...
