Includes social housing, social enrichment, social isolation, social buffering, and emotional contagion.
Marmosets are among the easiest of primates to provide with environmental enrichment. Like other higher primates, they need companionship, adequate space with incorporated complexity, some unpredictability in the environment, ways in which they can manipulate...
The management and success of a group-housing indoor/outdoor pen system for rabbits [mainly females] is described and discussed. Over a three-year study period a total of 141,000 rabbits were included in the assessment. The levels...
An attempt was made to form two groups of 6 previously single-caged adult female and 6 previously single-caged adult male rhesus macaques. The study was based on the premise that simultaneous introduction of familiar animals...
There is widespread concern that aged rhesus monkeys who have been housed singly for a long time would do better living alone than sharing a cage with a companion. Ten female and five male rhesus...
Possible social distress was evaluated in 20 adult rhesus macaques housed in compatible isosexual pairs (5 female pairs, 5 male pairs) for the purpose of social environmental enrichment. Serum cortisol concentrations of paired animals were...
Thirty paired female rhesus monkeys were tested in a control situation when companions had no privacy, and in an experimental situation when they were offered the option to move behind a panel and be alone...
Many scientists and colony managers assume that social housing is a beneficial living condition for all captive primates. Several older studies of primate development question the generality of this assumption. We recently tested this assumption...
Successful integration procedure of an adult female gorilla into an established breeding group is described.
The purpose of this study was to observe as many gorilla groups as possible and to compare their behaviour in different exhibits, social structures and visitor situation. Gorillas were studied in 15 zoos, they lived...
Several years of experience with pair housing of previously single-caged adult rhesus macaques and venipuncture in the home cage of cooperative, non-resisting animals lead the author to conclude that rhesus macaques are not as aggressive...
