| Outline of Final Research Achievements |
The epiphytic and epipsammic diatom community in the seagrass Zostera marina bed were studied based on the samples collected from the several coasts of Japan (Sado Island, Niigata Pref.; Yamagata Pref.; Akita Pref.; Nansei Islands). The species composition analysis of microflora on the seagrass and the morphological observation of dominant taxa were accomplished using light and electron microscopies. These studies have provided the taxonomical and ecological data of abundant species including 5 new species. Population dynamics examination of epilithic diatoms carried out biweekly in Tokyo Bay have shown that they have the difference in seasonal peaks of auxosporulation despite living in the same niche.
