The Future Of The Big Sagebrush Ecosystem: Plant Community Response To Grazing, Wildfire, And Invasive Annual Grass In A Changing Climate, Margaret Eleanor England

Theses, Dissertations and Capstones

Climate change is increasingly affecting the plant communities across the world. In the Western United States, these changes are affecting plant communities and their risk of invasive species, as well as the frequency and severity of wildfire. Big sagebrush (Artemisia tridentata Nutt.) ecosystems of the Western United States are facing threats of increasingly frequent wildfire and invasion of the annual grass cheatgrass (Bromus tectorum L.), which may be exacerbated by global climate change. Past studies have found cheatgrass to exhibit a positive feedback loop with wildfire, and climate change is expected to facilitate expansion of the cheatgrass …

The Coal River Basin: A 2009 Water Budget Study, R. Dale Biller

Theses, Dissertations and Capstones

The Coal River Watershed covers an area of some 890 square miles in southern West Virginia of which 863 square miles was investigated in this study. Both online and field data were collected over period from January 13, 2009 to January 13, 2010. The basin was studied as a closed system having an input, which was precipitation, and outputs, rainfall interception, evapotranspiration, and stream discharge that was separated into base flow and overland flow.

The effective rainfall of the watershed was calculated using the Thiessen polygon method to be 42 inches for the year, 48% of that water discharged by …

Chronic Acetaminophen Treatment Influences Indices Of Reactive Oxygen Species Accumulation In The Aging Fisher 344 X Brown Norway Rat Aorta, Sarath Meduru

Theses, Dissertations and Capstones

We have previously reported that aging in the Fisher 344 X Brown Norway (FBN) rat aorta is characterized by increased levels of ROS and alterations in cell signaling. Acetaminophen was found to scavenge free radicals in recent ischemia-reperfusion studies. Here we examined if chronic treatment with a therapeutic dose of acetaminophen attenuates age-associated increase in aortic ROS accumulation and signaling. FBN rats (27 month old; n=8) were subjected to 6 months of treatment with a therapeutic dose of acetaminophen (30mg/kg/day), with age-matched untreated FBN rats as controls. Protein oxidation levels were altered in control and treated aortae compared to aortae …

Using Geographic Information Systems To Organize And Coordinate Holistic Watershed Resource Management, John M.S. King

Theses, Dissertations and Capstones

Thesis research explores the use of Geographic Information Systems (GIS), such as ESRI’s ArcGIS and Google Earth, to organize and coordinate statewide, regional, and locally led watershed initiatives in West Virginia. Holistic Watershed Resource Management (HWRM) is an innovative collaborative approach to environmental protection designed to synchronize regional and local environmental assessment and restoration efforts. HWRM success is often attributed to an inclusive decision-making process, which seeks to build and coordinate cooperative partnerships among government agencies, private businesses, educational institutions, and non-profit organizations. A case study of the Morris Creek Watershed Association and detailed surveys of over 100 West Virginia …

Density, Length Frequency Distribution, Growth Rate, And Condition Of The Freshwater Mussel, ̲A̲N̲Od̲O̲N̲T̲A ̲I̲M̲B̲E̲C̲I̲L̲L̲I̲S Say 1829, In Six Ponds At The Clifton F. Mcclintic Public Hunting And Fishing Area, Mason County, West Virginia, Jeff L. Harmon

Theses, Dissertations and Capstones

Populations of the freshwater mussel Anodonta imbecillis Say 1829, were sampled from six ponds at the Clifton F. McClintic Public Hunting and Fishing Area in Mason County West Virginia from April 1986 to May 1987. One of the six ponds, pond 12, is contaminated with byproducts from the manufacture of TNT which occurred at the site during World War II. Population density, length frequency distribution, growth rates and condition indices were examined for each population to establish baseline data for the species and to determine what effects the contaminants might be having on these organisms.

Population densities ranged from 4.8 …
