Outline of Final Research Achievements

The submersible survey on kelp was carried out at four coastal areas in Russian Far East, and ecology of each species was revealed. Furthermore, current status of ISOYAKE at the sites under influence of warm current was recorded. Morphological investigation and molecular phylogenetic analysis were conducted using sporophytes collected, and biodiversity of kelp including rare local endemic species was elucidated and their phylogenetic relationships were inferred. And, it is considered that kelps that belong to a phylogenetic group in the southeastern Sakhalin and the southeastern Kamchatka were related to the species diversity in Hokkaido.
