The relationship between self-directed anxiety behaviors and cortisol in socially housed capuchin monkeys (Cebus [Sapajus] apella)

Non‐human primates are excellent models for the study of human social anxiety. Both humans and non‐human primates form complex relationships with others, and exhibit signs of distress when those relationships become unstable. Self‐directed behaviors, such as self‐scratching, have traditionally been...

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...

Management of weight and body condition for captive adult and aging chimpanzees (Pan troglodytes)

With the goal of finding a practical way to improve and/or maintain the body condition of overweight chimpanzees to promote health and welfare, several feeding protocols' effects on chimpanzee body condition scores (BCS) were evaluated. BCS were assessed at the...

Dams’ social behaviour and long-term cortisol profiles in response to their infants being nursery-reared

The influence of early rearing experiences on infants' social and neuroendocrine development is well characterized. However, little is known about the effects of nursery rearing (NR) on the infants' mothers. Such information is important in welfare considerations. In a two‐part...

Validating WelfareTrak® as a tool to improve the welfare of individual chimpanzees

WelfareTrak® is a web application that gives animal care specialists the opportunity to complete weekly species‐specific surveys to monitor positive and negative indicators of welfare for individual animals. WelfareTrak® generates reports and “flags” potential shifts in welfare status. The goal...

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...
