Outline of Final Research Achievements

Many species of coastal invertebrates with a planktonic larval stage often have a wide geographical distribution. The gastropods of the family Neritidae (Neritimorpha) include marine and freshwater species. Many species of neritids living in coastal rivers have an amphidromous lifecycle, and their larvae are dispersed by ocean current. As a result of population genetics using microsatellite data, there was no spatial genetic structure within Japanese population (Mainland Japan, Ogasawara Islands and Nansei Islands) of amphidromous species, and they were found to have high dispersal ability as with marine relatives. Fluorescent marking of neritid larvae is expected to be a useful tool in the field experimental studies on larval ecology.
