Plenary Symposium L3
Unifying Community Ecology and Ecosystem Ecology:
Biodiversity and Ecosystem Function
14:50 - 17:50, March 22, 2003
Organized by Kachi, N. and Kohyama, T.
Complex interactions among biotic and abiotic components characterize
biological communities. Ecosystem function can be understood through
cumulative quantification of these interactions. In this sense, there exits
no exact boundary between traditional community ecology and ecosystem
ecology. This plenary symposium addresses the linkage between community and
ecosystem processes performed over various systems. First we will focus on
the relationships between species diversity and ecosystem function within
a single trophic level and discuss the results from large-scale field
experiments. Next we will focus on a plants-herbivores-parasitoid system
and an aquatic system and discuss the role of interacting communities with
different trophic levels in structuring the changing ecosystems.
