| Research Abstract |
To reveal the role of ants as prey in terrestrial ecosystem, prey menu and prey preference of frogs and ant-eating arthropods, and effects of ants on survival and growth of a Japanese treefrogs were investigated. Hyla japonica and Microhyla ornate fed on many ants, however, they show remarkable preferences : they did not prefer to eat ant species with strong defensive weapons and small sized species. When we kept Hyla japonica by giving only ants, survivorship and growth rate were significantly different among ant species.
