Research Abstract

Based on the topographical analysis, 19 beaches were recognized as important habitat for maintaining the ecosystems of sandy shores in Japan. Restrictions on the gene flows between some of these beaches were suggested by the result of genetic analysis on four species. Especially, beach pea Lathyrus japonicus were proved to be highly informative species for inspecting management units of beach in local scale.
