Abstract

Intergroup interactions in primates are highly variable and can range from aggressive to affiliative. An extensive 13 year dataset on intergroup interactions between 14 mountain gorilla groups revealed that interactions were typically aggressive, but were occasionally peaceful. Variation in behaviour during intergroup interactions was due to multiple factors, including intergroup familiarity and relatedness, individual social status and the relative threat of the opponents. Furthermore, agonistic and affiliative interactions between group members were affected by intergroup conflict. This research has important implications for understanding the population dynamics of these endangered apes, and has contributed to our understanding of primate behaviour.
