Biogeographic patterns were investigated within a single species and among its congenerics. Smallmouth bass (Micropterus dolomieu) were characterized by portions of the cytochrome b gene and the control region although bass in Lake Erie were also evaluated using eight nDNA microsatellites. Overall, little population structure was observed among sites in Lake Erie which was surprising given that most male smallmouth bass exhibit nest site fidelity. But, these lake bass were divergent from bass residing in nearby tributaries indicating that lacustrine bass are reproductively isolated from riverine bass even though both groups may spawn in the same rivers. Adjacent riverine populations …
The Effect Of Wetland Size And Surrounding Land Use On Wetland Quality Along An Urbanization Gradient In The Rocky River Watershed, Marilyn S. Gunsch
The Effect Of Wetland Size And Surrounding Land Use On Wetland Quality Along An Urbanization Gradient In The Rocky River Watershed, Marilyn S. Gunsch

An intensive floristic evaluation of 17 Cleveland Metroparks (CMP) wetlands in the Rocky River Watershed (RRW) was undertaken to determine whether wetland size or anthropogenic disturbance in the surrounding landscape is a better predictor of wetland quality in this protected parkland. Wetland study sites were selected in three reservations, Hinckley, Mill Stream Run, and Rocky River. My research adds valuable information to the CMP wetland database and will contribute to its wetland management policies. Wetland quality was determined using the following floristic indices: species richness, non-native species, wetland species, mean coefficient of conservatism (C of C), floristic quality assessment index …
A Diatom Phosphorus Inference Model For 30 Freshwater Lakes In Ne Ohio And Nw Pennsylvania, Kyle C. Scotese
A Diatom Phosphorus Inference Model For 30 Freshwater Lakes In Ne Ohio And Nw Pennsylvania, Kyle C. Scotese

Nutrient enrichment in the form of anthropogenic phosphorous and nitrogen inputs has occurred in lakes worldwide. In the absence of historical water chemistry data, the extent to which this disturbance has impacted lakes in the Erie/Ontario drift and lake plain and Western Allegheny Plateau ecoregions remains to be determined. The objective of this study was to develop a diatom calibration set through analysis of surface sediments and water chemistry from 30 lakes spanning a phosphorous and nitrogen gradient in the glaciated regions of northeast Ohio and northwest Pennsylvania with an additional lake in New York. No current training set exists …
