Diatoms New to Ohio and the Laurentian Great Lakes

Author Institution: Department of Biological Sciences, Bowling Green State UniversityEpiphytic diatoms (Bacillariophyta) were collected from three marshes along the southern shoreline of Lake Erie during the summer and fall of 1977. Geographical distributions of 24 taxa new to the state of Ohio are described, and 149 and 34 taxa are reported as new for Lake Erie and the Laurentian Great Lakes, respectively. We attribute the large number of taxa new to the lake to a lack of previous littoral diatom studies, sampling technique, and habitat diversity within the littoral zone
