Behavioral enrichment for marmosets by a novel food dispenser

A mealworm dispenser was constructed and used to promote foraging activities in a group of 11 marmosets. The dispenser was not monopolized by a dominant individual for more than 10% of the total time.

Mealworm feeders as environmental enrichment for common marmosets

The mealworm feeder was made from rodent water bottles that were modified to have rows of holes on two opposite sides. The bottle hung horizontally from the top perch; it was filled to a 3 cm depth with waxmoth larvae...

Behavioral changes associated with introducing new group members in orangutans

Three of the introductions involved one male and one female, while the remaining three involved introducing a female to a male-female pair. .. Aggressive behaviors were very low during both the introduction and the post-introduction periods. Surprisingly, although the animals...

Effects of environmental enrichment on care-giving and infant development in marmosets

Twin infants from eight family groups were observed for the first 10 weeks of life. Non-enriched enclosures contained a nest box and branches. Enriched enclosures also had an artificial gum tree to stimulate the marmosets natural exudate gouging behaviour, wooden...

Conflict resolution following aggression in gregarious animals: a predictive framework

Knowledge of how animals manage their conflicts is critical for understanding the dynamics of social systems. During the last two decades research on gregarious animals, especially primates, has focused on the mechanisms of conflict management, mainly on friendly postconflict reunions...
