Mymou: A low-cost, wireless touchscreen system for automated training of nonhuman primates

Training nonhuman primates (NHPs) to perform cognitive tasks is essential for many neuroscientific investigations, yet laboratory training is a time-consuming process with inherent limitations. Habituating NHPs to the laboratory staff and experimental equipment can take months before NHPs are ready...

Personality, environmental stressors, and diarrhea in Rhesus macaques: An interactionist perspective

Previous research has repeatedly shown both personality and psychological stress to predict gastrointestinal disorders and chronic diarrhea in humans. The goal of the present research was to evaluate the role of personality, as well as psychological stressors (i.e., housing relocation...

Coping style and cortisol levels in infancy predict hair cortisol following new group formation in captive rhesus macaques (Macaca mulatta)

Social instability in primate groups has been used as a model to understand how social stress affects human populations. While it is well established that individual cercopithecines have different temperaments or personalities, little is known about how temperament mediates the...

A comparison of desensitization techniques to train rhesus macaques to take food from a human

Some primates express fear of or avoid interaction with humans, including accepting food. Counter‐conditioning training designed to reduce fear and increase the acceptance of food from a person's hand can reduce the stress an animal experiences and serve as a...

An assessment of porches as enrichment for singly housed cynomolgus macaques (Macaca fascicularis)

Effective environmental enrichment encourages usage, promotes species‐typical behaviors, and/or decreases abnormal behaviors. Porches are small cages that attach to the primary cage of an animal to provide additional space and a better view of the surroundings. This study aimed to...

Increases in feeding and destructible enrichment distribution in caged rhesus macaques (Macaques mulatta) provide some behavioral benefits

It is important to evaluate the effectiveness of environmental enrichment in meeting behavioral goals (e.g., decreasing abnormal behavior) and in making the best use of limited facility resources (e.g., money, personnel time). One/zero behavioral data on 12 abnormal behaviors were...

Enhanced physical environment in single-housed macaques: A long-term usage profile of cage extensions

Social housing is always preferred in the research environment; however, single housing is sometimes necessitated by scientific objectives or social incompatibility. In these cases, other environmental enhancements are developed to provide indirect social interactions. We developed a novel cage extension...

Providing feeding enrichment by hand mitigates anxiety among laboratory-housed rhesus macaques (Macaca mulatta)

Some husbandry procedures may be perceived as aversive by cage‐housed rhesus macaques. We assessed whether providing feeding enrichment by hand as opposed to placing it on a caging surface decreases anxiety responses to daily husbandry activities. Eleven adult males and...

A successful strategy for social housing adult male cynomolgus macaques in triads

At Charles River, we are committed to ensuring all animals have the highest level of care and welfare. For juvenile, subadult and adult female cynomolgus macaques (Macaca fascicularis), we have a near 100% success rate for social housing. Sexually mature...

Behavioral predictors of successful pairing of rhesus macaques (Macaca mulatta) at the visual contact phase of social introduction

Identification of behaviors early in the process of rhesus macaque social introductions that might predict social housing success would allow primate managers to best allocate resources and minimize animal stress by aborting introductions unlikely to lead to successful pairings. We...
