The reduction of species richness was the most remarkedble in Trichoptera and Mollusca. Species succession of macrozoobenthos was closely related to the changes in environmental conditions such as the isolation of the lake from the river, eutrophication, and disappearance of macrophytes. Perhaps, the latter two changes were more important.
