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...

Consequences of restraint stress on natural killer cell activity, behavior, and hormone levels in rhesus macaques (Macaca mulatta)

Animals were chair restrained and samples taken after 1, 2 and 3 hours. WBC and the percentage of neutrophils increased during the restraint period, while the percent lymphocytes and monocytes decreased. NK [natural killer cell] activity also decreased over time...

Affiliation tactics prior to a period of competition in captive groups of stumptail macaques

We show that, subjected to predictable daily routines, captive stumptail macaques adjust their affiliative interactions as if maximizing the benefits of a particular relationship. For 8 months the frequency of diurnal social grooming interactions and competition to groom a third...

A semi-natural habitat for housing small, nonhuman primates

A semi-natural habitat that was designed to house a group of squirrel monkeys is described. Animals maintained in this environment were healthy, and none of the animals exhibited locomotor stereotypies. This facility was easier and more economical to maintain than...

Maternal anxiety in rhesus macaques (Macaca mulatta) I. Measurement of anxiety and identification of anxiety-eliciting situations.

Visual monitoring and scratching were used as behavioral indicators of maternal and social anxiety in small captive groups of rhesus macaques. Young infants were especially at risk from other group members during the first weeks of locomotion away from their...

Influence of single caging on cellular immune function in female cynomolgus macaques (Macaca fascicularis)

Immune responses are affected by housing condition. These findings suggest that single caging modulates several aspects of cellular immune function in female cynomolgus monkeys.

Changes in activity levels of singly housed longtailed macaques when given the opportunity to exercise in a larger cage

Over a period of 36 days, each [single-housed] animal had 15 min per day access to a multicompartmental [large] exercise cage. Locomotion increased while stereotypical behavior decreased when the animals were in the exercise cage.

Activity patterns of captive and free-ranging long-tailed macaques (Macaca fascicularis)

In summary, the wild and captive macaques exhibited significant differences in four of the six activity categories we examined. There was no significant difference in the amount of grooming between the two populations counter to our expectations. Overall, the activity...

The effects of elementary environmental enrichment on the behavior of captive Java macaques (Macaca fascicularis)

The aim of this study was to determine the short-term effects of simple, cost-effective enrichment techniques. .... In the presence of simple enrichment [ranging 'from food to foliage to plastic objects'], isolate housed macaques showed slight decreases in abnormal behaviors...

Conflict avoidance among rhesus monkeys: coping with short-term crowding

Two contrasting models were examined, each of which predicts a relationship between space and aggression in primates. A 'spatial density' model predicts that as spatial densities increase aggressive responses also increase. A more recent 'coping model' suggests that, over long...
