Application Of Molecular Pathology Techniques To Understand Mechanisms Of Disease In Smallmouth Bass, Heather Leigh Walsh
Application Of Molecular Pathology Techniques To Understand Mechanisms Of Disease In Smallmouth Bass, Heather Leigh Walsh
Graduate Theses, Dissertations, and Problem Reports
In the Chesapeake Bay drainage, smallmouth bass Micropterus dolomieu are used as an indicator species of estrogenic contaminant exposure and have been implicated in fish kills and disease since 2005. In the Potomac River drainage, adult smallmouth bass have experienced mortality and disease and males have a high prevalence of intersex (testicular oocytes). Conversely, in the Susquehanna River drainage mortalities and disease of young-of-the-year smallmouth bass (YOY SMB) have occurred and resulted in a population shift to older and larger fish. The exact cause of these events remains unknown; however, factors such as poor water quality, contaminants, pathogens and parasites, …

Agricultural Intensification In The Midwest: Impacts On Regional Surface Humidity, Andrew Hill
All Graduate Theses, Dissertations, and Other Capstone Projects
An overwhelming majority of anthropogenic climate change studies have placed emphasis on biogeochemical agents, chiefly carbon dioxide emissions, which operate on a global scale. Fewer studies focus on biophysical factors such as land use/ land cover which operate on a regional or local scale. The impact from biophysical factors will continue to be reinforced with a growing human population and expanding resource demands. Of these factors, agricultural land use represents one of the largest, most extensive, and vital land use allocations.
The U.S. Midwest, dominated by rain-fed corn and soybean agriculture, is a key agricultural region which is lacking in …
