Integration of hand-reared gorilla infants in a group

Zoo-born gorilla infants could best be introduced into a group when about 1.5 to 2 years old; when younger or older, social integration becomes more difficult. An introduction to adult females in a small cage until strong social relations are...

Effects of manipulatable objects on the activity of captive capuchin monkeys (Cebus apella)

We conclude that providing straw and portable objects in an already well equipped cage is an effective means of long-term behavioral enrichment for [group-housed] captive capuchin monkeys.

Management of a harem breeding colony of rhesus monkeys to reduce trauma-related morbidity and mortality

Mortality rates per year were reduced from 13.4% to 3.5% when monkeys were maintained in permanent harems to which returning females were reintroduced compared to new social groups formed from aggregates of unfamiliar animals.

Social dominance and serum testosterone concentration in dyads of male Macaca fascicularis

Of 16 pairs, five dyads had to have their composition changed at some point [of the 8-month study period] owing to excessive fighting. [Pair formation procedure is not described.] Testosterone concentration and dominance were associated according to the type of...

An Ecological and Behavioral Study of the Pig-Tailed Macaque

Excellent overview of the species-typical behavior of wild pig-tailed macaques. Groups did not appear to select particularly large or emergent trees, but sleeping sites tended to be clumped on the upper part of the hill (which is to say, away...
