Abstract: It is important to understand the effects of ecological factors on aggression during feeding in order to link habitat characteristics to competitive regime and social relationships. Multiple habitat characteristics are likely to affect aggression, but few researchers have examined the effect of multiple factors on intragroup competition simultaneously. I examined the effect of 8 factors on aggression during feeding in wild Japanese macaques living in a coniferous forest in Yakushima: density of the tree species, feeding time, number of feeding sites within a feeding tree, number of cofeeding animals, intratree macaque density, food type, and rank and age of the focal individual. When macaques cofed with other individuals, food type, the number of feeding sites, and their interactions significantly influenced aggression. Aggression increased when macaques ate fruits/seeds versus other foods and as the number of feeding sites decreased. Primate socioecological models highlight the importance of clumped distribution of food patches as a correlate of intragroup contest. However, my study indicates that primatologists need to pay attention to the factors related to the current feeding tree-food type and feeding tree size with respect to monopolizability-in addition to the distribution of food in the entire home range.
