Includes social housing, social enrichment, social isolation, social buffering, and emotional contagion.
The authors provided different forms of environmental enrichment to six old laboratory male tufted capuchin monkeys (Cebus apella) and studied the behavior of the monkeys during a baseline period and during three enrichment periods. Each...
There are potential advantages of housing primates in mixed species exhibits for both the visiting public and the primates themselves. If the primates naturally associate in the wild, it may be more educational and enjoyable...
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...
A clear, perforated, plexiglass divider was installed between neighboring cynos to test whether it altered their proximity to one another, or prompted any behavioral changes. ... Adult male cynomolgus monkeys tend not to spend a...
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...
A colony of mice (base strain C57Bl6) was transferred to Oregon State University. Fighting was observed in six cages of males (2 to 5 mice per cage) at cage change, but not during daily checks...
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...
Environmental enrichment is a key component of rodent animal welfare since it influences the animal’s overall well-being, provides opportunities for activity, and encourages rodent appropriate behaviors. Many aspects of rodent enrichment have received a significant...
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...
The question was asked: “Research protocols sometimes require that compatible macaque pairs be physically separated for a limited time period (e.g., controlled food-intake studies; sample collection from chair-restrained subjects). Obviously – and as documented in...
