| Outline of Final Research Achievements |
The project attempted to reveal the diversification process of endemic species specific to chemosynthesis-based ecosystem. The planktonic larval dispersal, settlement and reproductive strategies including genetic population connectivity among discretely distributed local populations of the animals which live in chemosynthesys-based ecosystem were extensively studied and more than 10 papers were published in academic journals. These completed the planned studies, furthermore, we provided additional information regarding correlation between host-parasite life histories, in addition, physical factor for larval settlement was suggested. These achievements enable us to elucidate how so many specific species are inhabited in deep-sea chemosynthesis-based enviroments.

| Academic Significance and Societal Importance of the Research Achievements |
地球の生命は海で誕生したと考えられている。地球上に多様な生命が存在することを理解するためには海洋における生物の多様化のプロセスを明らかにする必要がある。本研究では海洋の中でも特殊な環境である化学合成生態系のみに生息する固有種を中心に、プランクトン幼生による生物分散、離れた集団間の遺伝的交流、成長に伴う生理・生態学的変化などを明らかにし、特殊な環境に生物が適応し生物に多様性がどのように生じてきたのかを明らかにした。これらの知見は、生物が海の中で多様化してきた過程を理解するだけでなく、多様な生物によって構築される海洋生態系を維持するためにも活用することができる。
