Relationship between social factors and pituitary-adroneocortical activity in female rhesus monkeys (Macaca mulatta)

Psychosocial stress in humans has been related to the occurrence or progression of certain diseases and a positive social environment has been shown, in some cases, to ameliorate this effect. In many experimental studies changes in serum cortisol levels have...

Group formation and behavioural changes with release to free-ranging in red ruffed lemurs, Varecia variegata rubra

The stresses involved in release and group formation, however, can temporarily produce new aberrant behaviours which are soon replaced by normal behaviours. Once released into the large enclosure, stereotypic behaviours became infrequent but did not disappear.

Factors influencing orangutan (Pongo pygmaeus abelii) behavior in indoor holding facilities and outdoor exhibits

Restriction of data collection to three weeks .... severely limits these results. ... What is interesting is the similarity in behavior in the two locations [indoors vs outdoors], despite marked differences in density and hours of the day observed. ......

Rawhide ‘chew-bones’ reduce abnormal behavior in individually housed adult rhesus macaques

Self-clasp showed a significant decline when the rawhide bones were present. We conclude that rawhide chew-bones are an effective, and relatively inexpensive method of enriching the environment of individually housed rhesus macaques.

Feeder logs, swings, and perches for primates

In order to reach the feeder logs, attempts to balance and walk the cord were necessary, and additional coordination was required to pick or dig the treat foods from the free-spinning logs. No data are included in this article.
