| Summary | Ecological similarities between 13 sand beaches were assessed based on the results of the hierarchical cluster analysis and DNA analysis. The cluster analysis was carried out using the presence-absence data of 8 coastal plants and loggerhead sea turtle, and suggested the existence of ecological boundaries on Hamamatsu-Ise and Miyazaki-Fikiagehama. The genetic analysis using partial sequence of coastal plant cpDNA showed the restriction of gene flow between sand beaches on smaller geographical scales. Theses result suggested the need for reviewing the regional coastal management units from the point of ecological and genetic features. |
