| Outline of Final Research Achievements |
The situation of coral reefs is becoming more serious due to climate change etc., and it is important to monitor them closely. In this study, we focused on environmental DNA in seawater and aimed to develop a new monitoring method that would enable us to detect corals simply by pumping seawater. Tank experiments were conducted to confirm whether corals and symbiotic algae could be detected in seawater, and the results showed that environmental DNA in seawater reflects well the status of corals in the vicinity

| Academic Significance and Societal Importance of the Research Achievements |
海水中の環境DNAは近傍に存在するサンゴの状況を反映しているのか、太平洋・インド洋の代表的な造礁サンゴであるミドリイシ属を用いて、水槽実験を行い検証した。実験に使用した全てのサンゴ、共生している共生藻類のDNA配列タイプを、海水中から検出することができた。水槽飼育したサンゴ由来の環境DNAは、それぞれのサンゴの水中重量・種組成と相関していることから、環境DNAを用いたサンゴのモニタリングは可能であると考えられる。
