ONU Student Research Colloquium
Geology, physiographic history, and land use are among the most important factors influencing benthic community structure and distribution in surface waters, especially lotic systems. Given the higher till concentrations in glaciated regions, does this impact the quality of riffle habitats and associated benthic communities? The objective of this study was to examine the influence of glacial history on benthic stream communities and physicochemical variables of a river in central Ohio. The Kokosing River transitions through several physiographic regions within Ohio including the Till Plains, the Glaciated Allegheny Plateau, and the Unglaciated Allegheny Plateau. From 2020-2021, periphyton, macroinvertebrates, fish, and selected …
