Research Abstract

Environmental variations of the physical and biological features within Iriomote Island, and the movement pattern of the Iriomote cat were clarified. And the relationship between them was analyzed. Natural movement (bats, birds, plants) and artificial movement (frogs, turtles, plants) were investigated both at present and in the past. From these results, the factors affecting island community and biodiversity were discussed in terms of variation of islands environments, its origin, special and historic relationship among islands, and indigenousness of island community.
