Outline of Research at the Start

大気CO2分圧の増加に伴う海洋酸性化は多くの海洋生物、特に炭酸カルシウム生物(サンゴや有孔虫など)に深刻な影響を及ぼす。本研究では「pH応答生物学の創成」を実現するべく、主に酸性化耐性サンゴ等を用いて低pH環境に対する生理・生態学的応答の解明、ならびに生理・医学研究者とタッグを組むことにより、分子レベルでの機構解明を遂行することによって、海洋生物が海水pHの変化にどのように応答・適応しているのかを解明する。さらに化石種を用いて、形態や群集組成を評価することで地球史上過去に生じたpH環境の変動に対し、生物がどのように応答し変化してきたのかを解明する。

Outline of Final Research Achievements

Increased atmospheric CO2 is now threatening the marine ecosystem by causing ocean acidification. Meanwhile, ocean pH is known to have changed dramatically throughout Earth's history. In this study, we aimed to assess the response of organisms to changes in seawater pH using marine organisms (corals) living in natural low pH analogues. In addition, fossil foraminifera, which are thought to have survived the pH era, and benthic foraminifera, which live in deep waters with a low pH environment. The results suggest that changes in seawater pH can be a major stress on organisms, but can also cause adaptation and evolution of marine organisms.

Academic Significance and Societal Importance of the Research Achievements

本研究は,社会活動に伴う気候変動によって,海洋生物や生態系が将来どのような応答を示す可能性があるのかを予測するのに役に立つだけでなく,その適応策を考案する上で貴重な科学的データを提供する。さらには現在みられる多様な生物種が過去の大気CO2濃度などの地球環境の変動と共にどのように進化してきたのかそのプロセスを解明する上での科学的なデータが得られた点で重要な成果が得られたと言える。
