Environmental Disturbance And The Distribution Of Rhinichthys Bowersi In West Virginia, Brooke Elizabeth Schlenker
Environmental Disturbance And The Distribution Of Rhinichthys Bowersi In West Virginia, Brooke Elizabeth Schlenker
Theses, Dissertations and Capstones
The Cheat minnow, Rhinichthys bowersi, has been designated a species of concern by the West Virginia Department of Natural Resources. Mitochondrial DNA analysis (Gladwell 2002) supports the origin of R. bowersi from hybridization between cyprinids R. cataractae and Nocomis micropogon. Previous investigators have hypothesized a relationship between fish hybridization and environmental disturbance. The habitat of R. bowersi has experienced severe environmental degradation from mineral and timber extraction. In this study, environmental quality was compared between stream systems in which parental species of R. bowersi were found with and without resulting hybridization. Environmental quality indicators included biotic diversity and stream structure …
A Seasonality Study Of The West Virginia Stream Condition Index, Gene T. Hilton Iii
A Seasonality Study Of The West Virginia Stream Condition Index, Gene T. Hilton Iii
Theses, Dissertations and Capstones
The West Virginia Stream Condition Index (WVSCI) has not been rigorously tested for the effects of seasonal data collection. Scientific literature regarding seasonal impacts on biological indices is surprisingly limited. But most literature does agree that seasonal signals are small in comparison to variation between all possible biological conditions. Recently stream data have been collected from a full range of seasons by both West Virginia Department of Environmental Protection and myself. In this study habitat, benthic macroinvertebrate data, and WVSCI values were analyzed for seasonality. For this reason multiple independent data sets were utilized. The analyses covered in this report …
