Males Matter: Increased Home Range Size is Associated With the Number of Resident Males After Controlling for Ecological Factors in Wild Assamese Macaques

摘要

Objectives: There is increasing evidence of male resource defense during intergroup encounters in non-human primates. Only few studies showed a reproductive benefit of having more males in a group, and evidence only comes from territorial species, or from species with relatively small male group sizes where males are less prone to suffer from collective action problems. We investigated the effect of male group size on home range size and female reproductive success in a non-territorial species with male dispersal and large male group sizes.
