New paper was accepted in Ecology Letters!

A new study investigated energy utilization in low-energy microbial ecosystems. Using a unique oxidation-reduction (redox) reaction network model, Mayumi Seto and Michio Kondoh (Tohoku University) explored community-level competition and cooperation. Results showed that microbial functional diversity and material cycling enhances energy use efficiency through metabolic handoffs. These self-organized interactions provide insights into effective energy utilization strategies and the functioning of microbial ecosystems.

New paper modeling explores the effect of increase in carbon dioxide on the coastal ecosystem regime shift

Mayumi Seto and the reserach group in Shimoda Marine Research Center, Tsukuba Univesity, assessed the effect of increase in carbon dioxide on the potential undesirable shift from a macroalgal-dominant state to a turf-algal dominant state in coastal ecosystems.

NWU collaboration team paricipates in projects funded through the Iwatani Naoji Foundation

Mayumi Seto is the principle ingestigator on "Installation of a solar-powred biotope and its application for carbon neutral education and ecological research" (2,000,000 JPY). This project will create a solar-powered biotope at NWU and monitor the changes in water quality and microbial community composition.

Mayumi Seto paricipates in projects funded through JSPS KAKENHI C

Mayumi Seto is the principle ingestigator on "Toward an integrated theory of the relationship between chemotrophic microbial communities and free energy" (4,160,000 JPY). This project aims to build an integrated thermodynamic and community-ecological theory for the relationship between microbes that harnesses chemical reactions and the Gibbs energy available for microbial community.
