Effects of social separation on rhesus macaque (Macaca mulatta) pairs in the laboratory

The benefits to nonhuman primates living in social groupings are well established. However, when certain research that requires housing subjects singly is performed, there are no guidelines as to how paired nonhuman primates should best be separated from one another....

Videotaped demonstrator improves efficiency of training chimpanzees to urinate on cue

Studies have shown chimpanzees can learn to perform tasks by watching live or videotaped demonstrators. The present study assessed whether female chimpanzees exposed to a videotaped demonstrator would learn a husbandry-related task, urinating into a receptacle on cue, faster than...

To squeeze or not to squeeze? A Discussion on LAREF, September, 2009

The discussion was started by the following questions: "Is the squeeze-back mechanism more or less stressful than the pole and collar system for removing a macaque from his cage for an IM (intramuscular) injection?" and "How are stress levels being...

Socialization of adult male cynomolgus macaques: benefits vs

At Charles River Laboratories (Reno, NV), we have a high rate of success when socializing juvenile and sub-adult cynomolgus macaques (Macaca fascicularis). Until recently, we would rarely attempt to introduce adult males through progressive contact panels due to previous unsuccessful...

Temperament ratings of laboratory rhesus macaques (Macaca mulatta): Effects of cage level and room composition

Measures of temperament in nonhuman primates generally reflect interactions between inherent individual characteristics and environmental contexts, and they may be indicators of physical and psychological well-being. Heritable aspects of temperament have been identified, but it is useful to evaluate the...

Rearing condition can affect success in social groups of rhesus macaques

Forming successful groups of rhesus macaques (Macaca mulatta) can be challenging. Males in particular do not always get along, and some need to be permanently removed due to fighting and trauma. Early rearing condition may play a role in social...

Termite mound feeders as naturalistic chimpanzee enrichment

These mounds (6 x 4 x 4 ft.) are small enough to fit inside the entrance to the outdoor play yard, yet large enough to prevent the mound from tipping over with several animals on top. First, we constructed a...

Factors affecting wounding aggression in a colony of captive chimpanzees (Pan troglodytes)

Previous research has suggested that chimpanzees (Pan troglodytes) display higher levels of aggression in captivity than in the wild. One of the challenges of captive management, therefore, is to balance the chimpanzees' need for social interaction with managements' desire to...

Effectiveness of perforated plexiglass dividers as social grooming devices between neighboring, individually housed adult male Macaca fascicularis
