Isotope applications in ecosystem ecology

Organizers: Nobuhito Ohte (Department of Forest Science, The University of Tokyo), Ichiro Tayasu (Center for Ecological Research, Kyoto University)

Focus:

Many kinds of isotope techniques have been applied for investigations of the biogeochemical cycling and food web structures of various aquatic and terrestrial ecosystems during past two decades. We attempt to review the background, history and recent progress of isotope related studies, and then to discuss about perspectives for the technical development and new applications, which will be available for ecosystem ecology in near future. The 1st to 3rd topics are basically on biogeochemistry. The 4th to 5th topics are on ecology, and food web studies, etc.
