Outline of Final Research Achievements

This study aims to reveal the coevolution process of primates and their gut microbiota. We clarify the changes of gut microbiota in response to the changes in primate diet, both at ecological and evolutionary time scales, and how it affects the digestion of the host primates. In our study in Yakushima, we clarified that the gut microbe species composition changes annually, in response to the seasonal fluctuations of the diet. Bacteria species diversity was highest in the leaf-eating season. We conducted in vitro digestibility assay using fresh feces of Japanese macaques in Yakushima as inoculum and dry leaf powder as substrate. Feces from highland, where macaques eat more leaves than lowland, are shown to have higher ability of fermentation.
