| Research Abstract |
We analyzed social structures of Japanese macaques using network analysis methods.
In a social grooming network, sub-groups, which were formed by strongly linked individuals, were nearly identical to maternal kin groups. Some individuals, who linked sub-groups strongly, had an important role in the maintenance of the grooming network of the whole group. Immature individuals entered into an adult grooming network through their close kin individuals and also maintained strong links to their peer-friends after they joined an adult network. Such bonds between peer-friends may affect links between sub-groups in a social grooming network.
