| Outline of Final Research Achievements |
In this study, we search the cases where aquatic plants are distributed and isolated in long distances such as between the Southern Hemisphere and the Northern Hemisphere or the Continent, and to verify the hypothesis that they occurred due to seed dispersal by migratory birds. As a result, it became clear that in some aquatic plants, seed dispersals caused their long distance isolation distributions. However, it was suggested that besides being highly probable by migratory birds as expected, there might be cases of wind dispersal.
