地球温暖化と植生，種多様性

ＩＰＣＣ （気候変動に関する政府間パネル）報告の検討

抄録

Vegetation and species diversity in the IPCC, Intergovernmental Panel on Climate Change, is introduced and reviewed. Shifting vegetational zones towards the polar regions may induce great changes in floristic compositions even with physiognomical changes. Changes in floristic composition might be greater in the present cool-temperate and subarctic regions than warm-temperate and subtropical ones. Comparative studies between the present and past floras have revealed species decomposition within physiognomically comparable vegetations.
