I started my research career in examining population dynamics of zooplankton in lakes and reservoirs. Immediately, my interests have been extended to issues on communities and ecosystem processes in aquatic habitats. This was because, when I was a fledgling, my favorite organism, Mijinko (微塵子 : see above pictures) provided me a chance to know how organisms within and between trophic levels have to interact each other to live in there. My research includes topics on species interactions such as predation and competition of zooplankton, production and decomposition processes, and material flows and cyclings. These studies involve experimental and field studies at various scales from beakers to large lakes. In my works, I have demonstrated that elemental (C:N:P) imbalance between resources and consumers is one of key factors in regulating not only community structures but also production and nutrient cycling efficiencies. I have extend this Ecological Stoichiometry approach to examining how external factors (climatic variations, anthropological impacts, etc.) interact with internal factors (trophic relationships) in sustaining and altering properties of aquatic ecosystems. It is my great pleasure if my works play a role for conserving biodiversity and ecological services in lakes and rivers in Japan and elsewhere in the world.
