| Outline of Final Research Achievements |
Among primate social systems, the multilevel society, in which smaller levels of social organization aggregate into larger units, is one of the most complex. Several nonhuman primate species including my study subject, i.e., proboscis monkeys, are characterized by multilevel societies. To achieve a better understanding of both the proximate mechanisms maintaining and the selective factors underlying proboscis monkey multilevel social systems, we examined their genetic patterns. In this study, we revealed the relatedness among individuals both in the one-male-multifemale and all-male groups. In addition, based on the data collected via the direct behavioural observation, I also potentially indicated the possibility of the high male-male competitions for females in their multilevel social system.
