Outline of Final Research Achievements

Biodiversity around boundary of land and water areas were studied on Amami Islands. Different vegetation types were found on coast, lower and upper part of rivers, respectively. Upper parts of rivers had highest plant diversity, and lower parts were invaded many exotic plants. Fauna of land snail had a similar distribution pattern to that of plants.
Fishes, shrimp, crab, other invertebrate, and algae were studies in the water ecosystem. Amami Islands had 1200 fish species, and other animals also had high diversities. The population of an endemic fish of Amami Island, Plecoglossu altivelis var. ryukyuensis varied greatly every year, number of shells in lagoon changed greatly after flooding by big typhoon in 2010. The diversity seemed to be maintained in dynamic condition.
