Aggression associated with changes in the dominance hierarchy of the mandrill troop at the Tulsa Zoo

Unlike their wild counterparts, captive animals cannot emigrate from the group if social incompatibility develops and captive animals have less space to flee from their aggressors. Therefore, complex social groups need to be monitored to ensure the animals' safety and...

Benefits of a positive reinforcement training program with bonobos (Pan paniscus)

Due to the training program, we have found that we can run the bonobos off exhibit at any time of the day and for any reason, without the fear that they won't go back on exhibit.

Behavioral changes in Lisbon Zoo chimpanzees after social housing*

The provision of manipulable objects [plastic brick, items of clothing] led to a reduction of self-directed behavior. It is suggested that manipulable materials can work as 'ice-breakers' for social interaction.

Ark design update: Primate needs and requirements

Primate needs and requirements are discussed in relation to appropriate captive housing and management. Providing a familiar, compatible companion during the hospitalization of juveniles or adults is rarely attempted even when doing so poses no risk to health or interference...
