| Outline of Final Research Achievements |
Compared to high-island, "animal-spreading fungi" and "non-air-spreading fungi" were not detected at all on the low islands, and only "wind-spreading fungi" were present. This is probably because the low-island was submerged under the sea surface in the past and all mycorrhizal fungi were wiped out. Since "animal-scattering fungi" and "non-air-scattering fungi" were detected on all high-islands, it is considered that overpasses have been formed between high-islands and continents in the past. The survival of such strains today suggests that there was no submergence after transfer.

| Academic Significance and Societal Importance of the Research Achievements |
植物や動物では、地球規模での生物多様性分布について数多くの研究成果が蓄積され、生物多様性の理論構築や保全活動に反映されている。本研究は、菌根菌分野においてこれまで未知であった亜熱帯地域の菌根菌群集構造を解明しようとするものである。本研究で得られる亜熱帯での菌根菌群集の知見は、既知の温帯、熱帯での知見と統合することにより、地球規模での菌根菌の多様性分布の解明に道を開く上で、重要な学術的意味をもつ。
