Outline of Annual Research Achievements

今年度はCovid-19の影響によって，観測航海が取りやめとなり，新規にデータ・サンプルは得られていない．そのため，これまで得られたデータやサンプルを用いて分析・解析を進めた．
今年度は，特にインド洋セクターを南北に走るトランセクト上の動物プランクトンの群集組成の変化，南大洋の低次生産において大きな影響をもつサルパの摂餌生態，漸深層において大きな生物量をもつソコイワシの食性に関わる研究を行った．最後の食性に関する研究では，DNAメタバーコーディングの手法を用い，一定の成果を得た．
また，固定液としてのルゴール液が，動物プランクトンにおいて形態観察，安定同位体分析およびDNA分析に用いることができることを検証し，証明した．この手法はセジメントトラップサンプルや各種のサンプルに応用できる．

Current Status of Research Progress

3: Progress in research has been slightly delayed.

Reason

サンプルの分析や解析，論文の執筆など一定程度は進んだが，海洋観測ができなかったことから新規のサンプルやデータが得られなかった．

Strategy for Future Research Activity

Covid-19による制限がどの程度になるかといった不確定な要素があるが，現有のサンプルやデータの解析に，これまでと同様に勢力をつぎ込む．食性解析にメタバーコーディングが応用できる目途がついたので，さらにDNAメタバーコーディングを適用した生態系研究を進める．
