Research


My study subjects are Japanese macaques in Yakushima, a southern island in Japan and diurnal primates in Sabah, a Malaysian state of Borneo. In both studies, my primary interest is the way animals interact with their environment. Ultimately, I would like to link the studies of these two sites, bridge between temperate and tropical primate ecologies, and depict a large picture of primate-forest interactions over the world.

In the studies of Japanese macaques, I have studied the effect of their habitat from the viewpoint of population ecology, feeding ecology and conservation ecology. Although primate-forest relationship is a hot topic in the current tropical ecology, relevant data is still deficient in temperate regions. One of the goals of my study is to clarify what kind of adaptation is required for primates to survive in temperate regions, which is a marginal habitat for primates.

In the studies of Bornean primates, my primary interest is the mechanism of coexistence of primate communities, under the effect of mast fruiting, a phenomenon unique to Southeast Asian tropical rain forests.
