Outline of Final Research Achievements

To understand the newly hypothesized deep-sea electro-ecosystems, we investigated how electrical current affects the physiology of marine benthos. We found that (1) benthos generates weak electrical current, (2) core metabolisms of benthos is affected by direction of electrical current flow, and also (3) behavior of benthos is also regulated by environmental redox potential. These findings demonstrate the importance of “electrical current” as a new parameter to understand the ecology of deep-sea electro-ecosystems.

Academic Significance and Societal Importance of the Research Achievements

2010年、地球上の新たな生命圏として深海電気生態系の存在が提唱された。今回得られた成果は、この未知の生態圏の存在を実証する上で、重要な知見を提供する。また、電気を用いることで底生動物の中心代謝と行動の制御が可能であるという発見は、新たな生態系の評価(センシング)技術や環境浄化技術に繋がると期待される。
