Macroenvironmental effects on the well-being of singly-caged male rhesus macaques (Macaca mulatta)

Determining the effects of the macroenvironment on the welfare of nonhuman primates can help identify their needs and guide their behavioral management. We evaluated the behavior of 37 adult male rhesus macaques in two housing settings at the Tulane National...

Amount and reciprocity of affiliative behaviors can predict pairing success in captive rhesus macaques (Macaca mulatta)

Socialization is one of the most important forms of enrichment for rhesus macaques. However, pair introductions can result in aggression and injury if partners are incompatible, even days after the initial introduction. Identifying predictors of long‐term compatibility early on can...

Removals based on low within-matriline relatedness can reduce severe aggression in captive rhesus macaques

Previous observational research of captive rhesus macaques suggests that higher coefficients of relatedness within matrilines are associated with lower rates of severe within‐matriline aggression and more cohesive grooming communities. We tested whether experimental removals targeted to increase the relatedness coefficient...

Social buffering and contact transmission: Network connections have beneficial and detrimental effects on Shigella infection risk among captive rhesus macaques

Group living in primates may impact the risk of pathogen acquisition in two ways. First, social connectedness makes individuals more susceptible to pathogens via contact‐mediated transmission. Yet in strongly bonded societies, having close connections and strong social ties can also...

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...
