We are studying the ecology, evolution, and diversity of various biological communities ranging from microorganisms living in various waters to fish as well as biogeochemistry and material circulation in terrestrial water. The main field is Lake Biwa, but we are also conducting research in other lakes and rivers.

Tropical forests are only 2% of the earth 's surface, but they are the habitat for more than half of the species of plants and animals. We are conducting research in tropical and subtropical forests both in and outside of Japan, to see how the rich biota of tropical forests is nurtured and maintained.
In nature, any living thing has some "connection" with other creatures, making up a network of ecosystems. Focusing on such networks, we investigate mechanisms of maintenance and creation of biodiversity and aim to establish a theoretical foundation for conserving biodiversity.
We are working on various ecological phenomena by utilizing techniques such as stable isotopic ratio and molecular analysis. Such new techniques reveal environment fluctuation, material flow, their mechanisms, or genetic basis of ecological phenomena that cannot be seen by ordinary methods. We are opening up new frontiers of ecological studies.
We describe phenomena of ecological systems using mathematical formulas. By solving them or analyzing them using computer simulation, we clarify the rule that dominates the phenomenon.
On the earth there are distinctive ecosystems in each region, where unique biodiversity can be seen. In the field of conservation ecology, we clarify the characteristics of each ecosystem and the interaction networks of the organisms found there. Through such approaches we think about what we should preserve and how we can preserve them in a better form.
