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, ...

Let's talk about ...
- Q Global warming increases number of exotic species in Japan, or not?
- Q If yes (or no), tell why and how?
[global warming does not means temperature increase only.] - Q We can not avoid 'global warming' in the present state. Shall we accept exotic species or not?
- Q Do we have any ways to restrict the invasion of exotic species?
[clipping, herbicides, habitat manipulation, or the other techniques?]
+ consider global scale (economy, etc.) - Q What shall we do for this problem?
