| Outline of Final Research Achievements |
Social style of Japanese macaques has been categorized into despotic among genus Macaca. We have conducted inter-population comparisons of social style in Japanese macaques. Specifically, we evaluated social style on the basis of allo-mothering in the wild groups, and aggressive vocalization during artificial feeding in the provisioned groups. A wild group at Yakushima and a provisioned group at Awajishima were found to be tolerant while the provisioned groups at Katsumaya and Shodoshima despotic. On the other hand, we found higher frequency in short allele of monoamine oxidase A at Yakushima and in long allele of androgen receptor at Shodoshima than in any other population. These results agreed with relationships between aggressive trait and genotype in rhesus monkeys and humans. Molecular phylogeny of mtDNA revealed evolutionary proximity between Yakushima and Awajishima populations. Inter-population difference of social style in Japanese macaques may reflect a genetic background.
