Summary
The general pattern of the data in this study shows that a riffle zone carries more species and, usually, more organisms/m2 than a slower current zone. The slower current zone, however, is still apparently able to support a larger number of organisms and species than a pool of standing water. In the West Fork of the Oak Creek system the dominant insects controlling diversity are the Trichoptera, particularly one species of Helicopsyche. Diversity in the fast current zone is high in the summer, and low during other seasons. Diversity in the slow current zone is highest in spring, but is also fairly high in summer. This reflects to a large extent the seasonal fluctuations in abundance of the dominant Trichopterans in the two habitats.
