ObjectivesTo understand the basic concept of the effects of global warming on ecosystem changes and its responses. I will talk about terrestrial ecosystems, and Dr. Suzuki will talk about oceanic ecosystems.Teresstiral ecosystems (by Tsuyuzaki)
|
Ocean ecosystems will be lectured by Suzuki K. |
Introduction (Guidance) Disturbances The main 'greenhouse gases' - relative contribution to the 'greenhouse effect'
Sun rays Life form Cancelled in this year due to few attendantsFor the reference, the followings are the contents in the last year__________________________________ Plant community Ecosystem Biome with reference to productivity and biomass
