Outline of Final Research Achievements

At a sandy shore in Sado Island, density of small crustaceans once declined by the construction of a new road along the shore, but the density increased afterwards. Survey on sandy shores along the Japan Sea coast of Honshu revealed 28 taxonomic groups and 7 types of community. Relationships between the occurrence of the communities and environmental factors were investigated with an aid of GIS data processing. As a result, three vertical zones were generally recognized. Statistical models did not detect any significant effects of artificial constructions (e.g. seawalls) on the occurrence of the shore communities. But, an examination using BIOLOG plates indicated that activity of bacteria was different between the shores with different land-use.
