Soil Phosphorus Levels In Residential Lawns And Comparisons Among Four Land Uses In Springfield, Missouri, Timothy R. Davis
Soil Phosphorus Levels In Residential Lawns And Comparisons Among Four Land Uses In Springfield, Missouri, Timothy R. Davis
MSU Graduate Theses
Eutrophication of surface waters due to high phosphorus (P) concentrations is an important water quality concern in Greene County, Missouri. Phosphorus enrichment has been linked to a variety of non-point sources including runoff from both agricultural and urban land uses. Soil P has been shown to be a source of P in runoff. The differences in soil P among different land uses may provide insight into which land use contributes more P in runoff. This study examines the soil composition, geochemistry and total P concentration of surface soil (0-5cm) in four land uses in Greene County, Missouri. The land uses …

Rating curves were used to correlate discharge and water quality variables. Separate rating curves were developed for …
Occupational Nepotism Among Law Firms: A Study Of Nepotism Beyond Anecdotal Evidence, Tracy L. Stout
Occupational Nepotism Among Law Firms: A Study Of Nepotism Beyond Anecdotal Evidence, Tracy L. Stout
MSU Graduate Theses
Although nepotism is not a new subject, there are not many studies addressing the psychological issues associated with the phenomenon, particularly in the workplace. The idea of “new nepotism” has emerged with the notion that some offspring have chosen the same profession as their parents, and have not been forced into a career decision or made an opportunistic decision regardless of their ability to perform. The purpose of this study was to explore workplace nepotism using an empirical research approach. Using a career choice and self-determination theory framework, a survey was devised and sent to 673 practicing attorneys in a …
Step-Pool Morphology Of A Wilderness Headwater Stream Of The Buffalo River, Arkansas, Aaron M. Nickolotsky
Step-Pool Morphology Of A Wilderness Headwater Stream Of The Buffalo River, Arkansas, Aaron M. Nickolotsky
MSU Graduate Theses
Step-pool and cascade morphology reflect the geological and climatic factors affecting channels in mountain watersheds. This study uses longitudinal and cross-section surveys of a headwater stream in the Boston Mountains of the Ozarks Plateau region in northwest Arkansas to describe channel form and develop quantitative models for comparisons with other regions. The Bowers Hollow Creek watershed (3.5 km2) is located within the boundaries of the Forest Service’s Upper Buffalo Wilderness Area. Step-pool morphology varies with the influence of lithology and sediment supply in the Boston Mountains. However, step height and wavelength relationships are generally similar to other regions. Distribution of …
Geospatial Analysis Of Gravel Bar Deposition And Channel Migration Within The Ozark National Scenic Riverways, Missouri (1955-2003), Derek J. Martin
Geospatial Analysis Of Gravel Bar Deposition And Channel Migration Within The Ozark National Scenic Riverways, Missouri (1955-2003), Derek J. Martin
MSU Graduate Theses
Historical land clearing is believed to be responsible for present-day channel instability in main stem reaches in the Ozark National Scenic Riverways (ONSR) in south-central Missouri. The nature of instability is related to the delivery of excess amounts of gravel sediment to stream channels and higher rates of lateral bank erosion. These conditions are of concern to resource managers because of the potential damaging effects on recreational facilities and aquatic habitat. The purpose of this study is to develop a geographic information systems (GIS)/remote sensing (RS) based methodology to monitor spatial patterns of gravel deposition and lateral channel migration within …
Mercury Contamination Of Channel And Floodplain Sediments In Wilson Creek Watershed, Southwest Missouri, Willard E. Rodgers Ii
Mercury Contamination Of Channel And Floodplain Sediments In Wilson Creek Watershed, Southwest Missouri, Willard E. Rodgers Ii
MSU Graduate Theses
Mercury (Hg) is a pollutant affecting aquatic environments and human health world wide. Sediments in urban streams can store Hg from historical industrial waste releases in channel and floodplain deposits. Subsequent erosion of these deposits can remobilize sediment-bound Hg impacting downstream receiving waters. This study describes the distribution of Hg in floodplain and channel sediments of Wilson Creek and its tributaries using geochemical sediment analysis and cesium-137 dating. The upper Wilson Creek watershed drains the southern two-thirds of Springfield, Missouri. Results indicate that Hg concentrations in overbank and active channel sediments along the entire stream length are elevated above the …

Consequences Of Reservoir Drainage On Downstream Water Chemistry, Suspended Sediment, And Nutrients, Southwest Missouri, Mark W. Bowen
MSU Graduate Theses
Construction and subsequent draining of reservoirs can have dramatic affects on the release of nutrients and sediments to waterways. This study describes how the temporary draining of a small reservoir for dam repair influences downstream water quality. The Valley Mill Reservoir has a surface area of 6.1 hectares and volume of 150,000 m3 when filled. Water chemistry monitoring and water sampling were performed at six sites during baseflow and ten sites during runoff events for one year. Water samples were analyzed for total nitrogen (TN), total phosphorous (TP), and total suspended sediment (TSS) concentrations. Results indicate that draining of Valley …
Phosphorus Contamination And Storage In Bottom Sediments Of The James River Arm Of Table Rock Lake, Southwest Missouri, Marc R. Owen
Phosphorus Contamination And Storage In Bottom Sediments Of The James River Arm Of Table Rock Lake, Southwest Missouri, Marc R. Owen
MSU Graduate Theses
Eutrophic conditions in the upper James River Arm (JRA) of Table Rock Lake have been linked to phosphorus (P) inputs by wastewater treatment facilities and increasing urban development in the upper James River Basin (3,770 km2). Since the majority of P in aquatic environments is bound to sediments, bottom sediment can function as both a source and sink of P in lake systems. This study evaluates the spatial distribution, physical and chemical characteristics, and storage of sediment-P in the active layer ( < 5cm) of bottom sediments in the JRA. The JRA makes up about 20% of Table Rock Lake’s surface area, contributes about 30% of the inflow, and has the poorest water quality of the entire lake. For this study, grab samples were collected in the main arm and tributary coves at the deepest part of the lake and at several shallow sites along the main arm. Concentrations increase in a down-lake direction in the main arm ranging from 5 to >2000 ppm P. However, water-column P concentrations show a decrease down-lake, indicating that sedimentation is removing P from …

History Of Sedimentation And Contamination In Valley Mill Reservoir, Springfield, Missouri, Susan S. Licher
History Of Sedimentation And Contamination In Valley Mill Reservoir, Springfield, Missouri, Susan S. Licher
MSU Graduate Theses
The Valley Mill Reservoir (VMR) was constructed between 1851 and 1871 and drains an important recharge area of the drinking water watershed for Springfield, Missouri. Presently, management efforts to protect downstream water quality are aimed at using VMR as a non-point pollution and sedimentation basin since its watershed is planned for continued urban development. The morphometry of VMR is typical of most reservoirs with an elongated basin and the deepest point being near the dam. Sedimentation within the reservoir has created a delta formation with upstream wetlands and floodplains acting as part of the delta especially during the past. Little …

Habitat Use Of Urban Bats In Springfield, Missouri, Sarah Jane Robertson
MSU Graduate Theses
During the summers of 1998-2000, the Anabat II bat detector system was placed in a mosaic of habitats within Springfield, Missouri and surrounding rural areas in southern Missouri to compare the activity indices of nine bat species between urban and rural environments. A total of 1,876 echolocation call sequences was recorded, identified to species and analyzed; 1,066 were from 42 Springfield sites, and 810 were from 22 rural locations. For all species combined, urban bat activity tended to be higher than rural activity, but those differences were only significant at the reading taken 3 hours after sunset. Eptesicus fuscus activity …
Spatial Patterns And Floodplain Contributions Of Mining-Related Contaminants In Chat Creek Watershed, Southwest Missouri, Jimmy Trimble
Spatial Patterns And Floodplain Contributions Of Mining-Related Contaminants In Chat Creek Watershed, Southwest Missouri, Jimmy Trimble
MSU Graduate Theses
Past mining activities have left a legacy of water quality problems in the Tri-State Mining District. Contemporary environmental risks stem from the release of lead and zinc from mine tailings previously dispersed far downstream in alluvial deposits as well as abandoned tailings piles. This study examines mining-related heavy metal contamination in the Chat Creek Watershed. Chat Creek drains the area near Aurora, Missouri on the eastern edge of the Tri-State District where mining occurred from 1886 to about 1930. This study identifies the spatial distribution of metal contamination in fluvial sediments and quantifies the role of bank erosion as a …
Prayers For The Wild At Heart: Personal Essays, Michael Lewis Frizell
Prayers For The Wild At Heart: Personal Essays, Michael Lewis Frizell
MSU Graduate Theses
It is my contention that writers wll violate their own privacy, that is, reveal their innermost thoughts and dreams, when they are comfortable with the manner and context in which their privacy is broken. Thus, the vehicle for "crossing the line" is important. By discovering their "personal voice" through utilization of the narrative personal essay, writers will be able to break the fear of writing in a voice that reveals the essence of their souls. The personal essay is not a work of fiction. In this mode, writers are forced to self-reflect on their subject, accessing a mercurial memory, then …

This watershed has been subjected to an intense period of Pb-Zn mining that began in 1886, peaked in 1916, and ended by 1930. The objectives of this study are to: (1) determine the magnitude and distribution …
In Harm's Way: The Continued Relevance Of The U.S. Navy's Forward Presence Mission In The Post-Cold War World, Christopher B. Earls
In Harm's Way: The Continued Relevance Of The U.S. Navy's Forward Presence Mission In The Post-Cold War World, Christopher B. Earls
MSU Graduate Theses
With the breakup of the Soviet Union, the United States Navy has seen the fleet shrink from nearly 600 ships in 1988 to 320 ships in 1999, with a planned reduction to 305 ships by 2004. While the fleet has been reduced by nearly 50 percent over the last decade, the deployment of U.S. naval forces has continued at near-Cold War levels. The result is a mismatch between the national security requirements that naval forces are called on to support, and the forces available to meet those requirements. Some have suggested that the traditional forward presence mission of the Navy-Marine …

The Old Reliable: The History Of The Springfield Wagon Company, 1872-1952, Steven Lee Stepp
The Old Reliable: The History Of The Springfield Wagon Company, 1872-1952, Steven Lee Stepp
MSU Graduate Theses
Long before the day of automobiles, trucks, and improved highways, Americans were a people on wheels; wooden wheels. The great demand for wagons spurred the development of a tremendous wagon manufacturing industry and of gigantic wagon companies. Some of the larger wagon manufacturers eventually enjoyed annual sales approaching a million dollars. Wagon building became big business during the late 1800's, and, as such, it was subject to all the evils as well as the benefits resulting from that period of rapid industrial expansion. The men who built and operated the nation's largest wagon companies battled each other as furiously as …
