Mirror reactions in a zoo colony of cebus monkeys

The intermittent exposure to a mirror over a 5-week period produced species-specific social reactions [in group-housed animals] to the mirror. The duration of mirror viewing of subadults was over twice that of the adults. The average viewing time decreased substantially...

Utility of immune measures for evaluating psychological well-being in nonhuman primates

These studies indicate that the psychological disturbance evoked by rehousing and disruption of social relations is sufficient to cause a substantial change in the pattern of leukocytes observed in peripheral blood.

Cage enrichment, physiology, and behavior in nursery-reared rhesus monkeys

Calm [single-caged] control animals and stressed [single-caged] enriched animals exhibited higher cortisol values. The enriched animals had lower cortisols when they appeared calm and higher cortisols when they appeared stressed. .. Control animals exhibited the opposite pattern, and calm control...

Long-term arrhythmia analysis of primates pretreated with pyridostigmine, challenged with soman, and treated with atropine and 2-PAM

Heart rates were significantly lower on weekend, when there was minimum research activity in the facility, while they were noted to increase on weekdays. These alterations suggest that increased heart rates in the animals were closely associated with work activity...

Environmental enrichment and its effects on the individual

In macaques and baboons, stereotypy is reduced or stopped by supplying "one or more perches ... and other cage furniture", especially "a woodchip substrate which includes food items ... as provisioned substrate for foraging"

Reducing the suffering of primates in captivity: Testing toys for primates

Subjects had access to commercial toys during a three-day period. With caged primates we have encountered problems that lead us to believe that even the most durable toys are not unbreakable by some primates.

Environmental enrichment for monkeys used in behavioral toxicology studies

Overall, this program helps to reduce self-mutilation and vices associated with caging and by considering the monkey's natural instincts along with experimental requirements, benefits both the science and the monkey. ... The pools have been a tremendous success with the...

Resocialization of captive chimpanzees: An amelioration procedure

Group formation protocols are described. 59 of 60 chimpanzees were successfully resocialized to compatible group living. Severe wounding has not occurred in our facility, perhaps due to luck, but more likely due to the close daily behavioral monitoring of each...

Signs of enrichment: Towards the psychological well-being of chimpanzees

By providing the chimpanzees with a wide variety of things to do we have also created an environment that is conducive to interesting social interaction. This is exactly the type of environment one would expect to help a chimpanzee achieve...
