Overview
Dynamics of population or community after the subsidence will be monitored at area B in rocky shore of Oshika Peninsula. In area B, survival and growth of Eisenia bicyclis (brown algae) and hervivorous gastropod, Omphalius rusticus will be monitored, and their population dynamics after subsidence will be clarified in relation to various environmental factors.To clarify the effect of O. rusticus on E. bicyclis, exclosure experiment of O. rusticus will also be conducted.
