Macaque

An enrichment programme for group housed Rhesus macaques (Macaca mulatta)

The Centre for Macaques (CFM) houses Rhesus Macaques (Macaca mulatta) in groups of 2 to 18 individuals with ages ranging from birth to 16 years. We strive to create a comprehensive enrichment program with a variety of diverse types catering...

From Fish to Mice to Monkeys in Research: Challenges and Opportunities for Mental Well-being

This chapter focuses mainly on animals in medical research. Many, especially the smaller species such as rat, mice, and zebrafish, may be seen only a few minutes a day by their human caregivers. Most laboratory animals are kept in confinement...

Behavioral Biology of Laboratory Animals

This 30-chapter volume informs students and professionals about the behavioral biology of animals commonly housed in laboratory and other captive settings. Each species evolved under specific environmental conditions, resulting in unique behavioral patterns, many of which are maintained in captivity...

Physiologic consequences of housing adult male cynomolgus monkeys (Macaca fascicularis) in heterosexual pairs: A pilot study using implanted biotelemetry

Facilities may forgo attempting to socially house adult males due to fear of animal injury, study disruptions, and confounding data results. To leverage the potential advantages of male–female pairs, and to understand the impact on measures typically used in safety...

Cortisol and catecholamine concentrations are affected by repeated relocations of adult female rhesus monkeys (Macaca mulatta)

In captive primate facilities, relocations—moves, within the facility, from one cage to another—can be common events. On the one hand, relocations are generally regarded as relatively benign events, as past studies have generally shown only transient elevations in cortisol concentrations...

Establishing a predictable cue for catches to reduce reactivity to management events for captive rhesus macaques (Macaca mulatta)

Psychological duress can emerge from the perceived lack of predictability such that, in captive circumstances, reliable signals for aversive events can afford animals with the opportunity to behaviorally and physiologically prepare. Does a reliable and unique signal cue for an...

Advancing non-human primate welfare: An automated facial recognition system for unrestrained cynomolgus monkeys (2025)

Cynomolgus monkeys (Macaca fascicularis) are vital in biomedical research, particularly for drug development and studying neurological diseases. However, accurately identifying individuals in group housing environments remains a significant challenge. This paper presents a near real-time facial recognition system tailored for...
