| Outline of Final Research Achievements |
We evaluated the adaptations of early life history stages, i.e., embryos, larvae, and juveniles to environmental factors including salinity and temperature in terrestrial hermit crabs Birgus latro and five Coenobita species which are distributed in southern Japanese islands. Coenobita purpureus has the most lower thermal tolerance limit and its overwintering population was found in the Boso Peninsula and Miura Peninsula of the main Island of Japan. Additionally, Coenobita violascens showed a specific distribution; it inhabited the estuary including mangrove areas. Furthermore, our population genetic studies revealed that the C. purpureus population in the Ogasawara Islands was genetically distinct from other regions with genetic panmixia.
