Outline of Research at the Start

気候変動や土地利用の集約化・放棄など、大規模・広域的な環境変動の生態系への影響が顕在化している。本研究は、広域的な環境変動に対する生態系の応答予測の汎用的な枠組みを作ることを目的とする。特に、生物群集内の生物間相互作用をモデル化し、これまで理論や実験等では困難であった、複雑な野外群集全体を対象とした安定性の広域的な定量化や安定性自体の環境依存性の解明を可能にする手法の開発を行う。その上で、淡水魚類等の野外生物群集を対象として上記の手法の適用・検証を行う。さらに、気候変動や土地利用変化などの広域的な環境変動が野外生物群集の組成や安定性にどのような影響を与えるかを評価・予測する。

Outline of Final Research Achievements

The impacts of global environmental changes, such as climate change and land use intensification and abandonment, on ecosystems are becoming increasingly apparent. This study aims to create a general framework for predicting the response of ecosystems to global change. Specifically, we aimed to (1) utilize a simultaneous distribution estimation model that explicitly considers the interactions among the many organisms that make up a community, (2) extend Energy Landscape Analysis recently introduced to the area of ecological research to evaluate and quantify the stability of community composition, which has been a difficult task, especially at large scales. In addition, we applied and verified the above methods to microbial communities, and to freshwater fish communities of which observation data were collected in Japan, Europe, and North America.

Academic Significance and Societal Importance of the Research Achievements

本研究は、生態系の環境応答予測の普遍的な枠組みを構築することで、生物群集内の生物間相互作用を明示的に考慮し、これまで理論や実験等では困難であった複雑な野外群集全体を対象として安定性の広域的な定量化や安定性自体の環境依存性の解明につながる方法論を確立した。
