Pair formation among adult female long-tailed macaques (Macaca fascicularis)

Most social units were formed by choosing partners at random and removing a partition between adjacent cages. Thirteen of 15 pairs, and [only] 1 of 4 trios, remained compatible for 4 months or longer following resocialization. Two additional successful pairs...

The effects of two novel objects on the behaviour of singly caged adult rhesus macaques

Single-housed subjects engaged in almond stick use 5.8% of 15 minute-observation sessions. The corresponding figure for nylon ball use was 2%. No adverse health effects of stick ingestion were noted among the subjects.

Changes in behavior and heart rate associated with pair formation in adult female rhesus monkeys (Macaca mulatta)

Mean heart rate increased significantly during pair housing. Bizarre postures decreased, while other abnormal behaviors including pacing, stereotypic actions, and self-injury did not change significantly. [Pair formation technique is not described.]

Customizing an enrichment program: Rhesus monkeys

An analysis of the time budget (agonistic behavior is excluded) of rhesus macaque groups kept in free-ranging and confined [corncrib] condition. Adult animals spent about the same amount of time engaged in social grooming in both conditions (17%) but spent...

Effect of cage size and environmental enrichment on behavioral and physiological responses of rhesus macaques to the stress of daily events

Neither heart rate nor activity varied significantly between the two cage sizes [of barren cages]. Adult, single-housed female rhesus macaques responded with a significant rise in heart rate to being removed from their home cage and replaced after the cage...

An evaluation of capuchin monkeys trained to help severely disabled individuals

All interviewees identified their monkey's behavior as acceptable and none reported incidents of unacceptable behavior. .. Monkeys can be taught to perform a variety of useful taks [listed in this survey] for disabled individuals.

Agonistic behavior responses of socially experienced, unfamiliar adult male rhesus monkeys (Macaca mulatta) to pairing

The present data demonstrate that unfamiliar adult male rhesus monkeys may generally be paired directly with each other without undue risk provided partners have previously lived with another male companion. This is congruent with the findings made with adult females....
