Outline of Final Research Achievements

We analyzed carbon and nitrogen stable isotope ratios of zooplankton from the sub-arctic to tropical western North Pacific and the Chukchi Sea. Our results clearly showed that a similar regularity between the food chain and the N / C isotope ratio, regardless structure of the food web and biological species. Isotopic analysis of meso-zooplankton community in the Kuroshio current region suggested that the offshore area use energy sources derived from regenerative nutrient and nitrogen fixation. In addition, the isotopic ratios of the community of diatoms, cyanobacteria and juvenile fish, large phytoplankton is minor as a trophic source of meso-zooplankton community in the Kuroshio and major prey items of fish larvae are small copepods.

Academic Significance and Societal Importance of the Research Achievements

近年、地球システムの仕組や機能、その変動と持続可能性に関する統合的研究が精力的に行われている一方で、海洋生態系に関しては、気候変動が食物連鎖を介し水産資源として重要な魚類など高次捕食者に与える影響については未だ大きな不確実性が残されている。本成果で得られた「食物網の構造や構成する生物が異なっても食物連鎖とN/C同位体比には統一的な規則性がある」ことは、低次および高次の両端から食物連鎖を評価できる手法の1つとして、これまでの物質循環研究に加え、低次の食物連鎖と有用魚種の回遊経路・生息地域の検証や、持続的・効率的な海洋生態系利用について提言などへの発展が可能となると考えている。
