An Analysis of the Shore Beetle Communities of Some Channelized Streams in Northwest Ohio (Coleoptera)

Abstract

The present shore beetle communities of some northwest Ohio streams channelized between 1937 and 1973 were studied. Quantitative and qualitative analyses were made to determine the effects of channelization on the community and the results are discussed. Ninety species, chiefly Carabidae, Heteroceridae and Staphylinidae, were collected; at least 20 not previously reported from Ohio. In addition, some species associations are noted.
