Outline of Final Research Achievements

Feeding strategies of African cercopithecids were investigated by using ecological, genetic and morphological methods. Food overlaps among guenons were different between combinations of guenon species. Colobus monkeys used the same food “species” which guenons used, but the differences of “parts eaten” were found between colobus monkeys and guenons. Monkeys, which frequently fed on hard leaves or hard fruits, had strong jaws and teeth adapting to wear down. The difference of bitter taste receptor gene repertoires among investigated species was found and this difference was suggested to be related with the difference of feeding strategy of each species.
