Ground substrate affects activity budgets and hair loss in outdoor captive groups of rhesus macaques (Macaca mulatta)

This study investigated the influence of grass vs. gravel substrate on activity budgets and degree of hair loss in seven groups of captive rhesus macaques housed in outdoor enclosures at the California National Primate Research Center. Groups having grass substrate...

Cooperation counts

Rhesus macaques were trained to take juice from syringes. Operant conditioning for oral dosing has many applications. If macaques are trained to accept liquid from syringes, they can receive test compounds in pharmaceutical testing by voluntarily accepting the liquid and...

Training rhesus macaques for venipuncture using positive reinforcement techniques: A comparison with chimpanzees

All subjects were trained to place an arm in a 'blood sleeve' and remain stationary for venipunctures. We were able to obtain repeated blood samples from 75% of [eight adult] macaques. ... An average of 257 minutes was needed to...

Physiological and behavioral effects of social introduction on adult male rhesus macaques

Pair housing of laboratory macaques is widely considered to lead to positive changes in well-being, yet the process of introduction is viewed as potentially stressful and risk-prone. Behavioral and physiological data were collected on eight adult male rhesus macaques before,...

A rhesus monkey model of self-injury: effects of relocation stress on behavior and neuroendocrine function

BACKGROUND: Self-injurious behavior (SIB), a disorder that afflicts many individuals within both clinical and nonclinical populations, has been linked to states of heightened stress and arousal. However, there are no published longitudinal data on the relationship between increases in stress...

Rhesus macaque kindergarten

Weaned macaque infants are often raised alone or in pairs. It is my experience with rhesus macaques that an optimal environment for these youngesters is a kindergarten in which one adult animal keeps order. I always enjoyed observing the animals....

Preferred contents of movies as an enrichment method for Japanese macaques

In order to improve the quality of life of captive Japanese macaques (Macaca fuscata), we investigated the effective content of movie presentations, which we expected would satisfy a need for visual and social stimuli. Because Japanese macaques are popular experimental...

Wounding incidence in isosexual pairs of adult rhesus macaques (Macaca mulatta) during introduction and in varying pair housing conditions

The aim of this study was to compare the incidence of wounding in isosexual rhesus macaques paired in three styles of housing: continuous full contact (FC), intermittent full contact (IC: frequent separation), and protected contact (PC: separation by a partition...
