Patterns of vocal sharing and social dynamics in a captive group of Campbell's monkeys (Cercopithecus campbelli campbelli)

Résumé

Although vocal sharing is widespread at several phylogenetic levels, few descriptions concerned primates. The present study involved the dynamics of vocal structures and social organization in a captive group of Campbell's monkeys (Cereopithecus campbelli campbelli) at 3-year periods, using precise sound recording and comparison. The authors focused on combined harmonic 6, calls, often involved in vocal exchanges and associated with approaches. Each female produced 1 to 4 variants, shared, or not, between individuals. Changes appeared between years in the form of disappearance, appearance, or transformation of variants. There was a decrease in, the global degree of sharing over the years. Greater changes were observed after social disturbance. Sharing would be more-important in disturbed than stable groups to advertise bonds.
