Effect of increased space on behaviors of captive chimpanzees

The results suggest that increased space may reduce some social interactions. It is not clear if levels of social activity [in general] in smaller spaces are 'abnormally' high, and are reduced to more 'normal' levels following an increase in available...

Stereotypies: a critical review

Stereotypies are physically or temporally associated with lack of stimulation, or events such as acute stressors or the expected arrival of food. All these environments may involve chronic conflict and frustration and hence stress. Other stereotypies are relatively independent of...

Effects of social interaction on well-being: Development aspects

Captive animals will be served best if developing individuals are raised at least through weaning by their biological mothers and have the experience of living in a social group that approximates the size and age-sex composition of the group in...

Simple toys do not alter the behavior of aged rhesus monkeys

By the fourth week of exposure only 36% of the [single-caged] monkeys were seen using them [rubber toys, nylon ball, gnawing stick] even once, and only 17% did so during more than one of three observations.

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.]

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...

Ecological requirements of macaques

In captive colonies, social and rearing environments and modes of provisioning often depart significantly from those that occur in nature. Within limits, naturalistic patterns can serve as useful models for improving the quality of life for captive macaques.
