Subsection: Plants and Plant communities in Japan - A brief introduction -

Syllabus

Temporal and spatial patterns of plant communities. Spatial pattern: plant community structures with different sceales, as viewed from sattelites, airplaines, and earth.
Temporal pattern: community dynamics and succession. How do plant community structures change with time?
What power promotes changes in plant community structure? - Disturbances, interactions, ...
