The role of intragroup agonism in parent-offspring relationships and natal dispersal in monogamous owl monkeys (Aotus azarae) of Argentina.

摘要: Agonistic behaviors are common in many group-living taxa and may serve a variety of functions, ranging from regulating conflicts over reproduction to defending food resources. However, high rates agonism not expected occur among close relatives or individuals established mating relationships, which characteristics monogamous groups. To contribute our understanding within socially groups, we collected behavioral demographic data Azara's owl monkeys (Aotus azarae) the Gran Chaco Argentina 14 years. We examined factors related age, sex, kinship, context evaluate predictions hypotheses that functions regulate dispersal it mediates competition for and/or mates. Intragroup was relatively rare: group rate approximately one event every three half hours. Rates were generally similar both sexes, but there marked differences age categories. Agonism performed by adults more frequently directed at subadults than younger offspring. In contrast, agonistic interactions involving infants very rare. Among between subadults, much actors recipients, suggesting influence natal subadults. events most frequent during foraging, also occurred bouts social behavior. Overall, results suggest serves as mechanism dispersal, likely plays role mediating feeding competition.
