River Sediment Sampling Methods- Causeway Building And Removal, Dillon Dittmer
River Sediment Sampling Methods- Causeway Building And Removal, Dillon Dittmer
Department of Environmental Studies: Undergraduate Student Theses
Abstract The Environmental Protection Agency (EPA) and U.S. Fish and Wildlife Service (USFWS) suspect that causeways have a negative impact on river ecology both when installed and when removed. The Nebraska Department of Roads routinely uses causeways as a tool in the construction and repair of bridges. Although research has not been conducted on the impact of causeway building and removal data has been collected about the impact of dams, causeways, etc. on estuaries. This data is considered subjective and authors often cite sampling methods as a source of error. Currently there are no widely used handheld sampling methods that …
The Effects Of Ornamentation On Wolf Spider Foraging, Mari Pesek
The Effects Of Ornamentation On Wolf Spider Foraging, Mari Pesek
Department of Environmental Studies: Undergraduate Student Theses
ABSTRACT: As a secondary sexual trait that can increase reproductive success, ornamentation is believed to be costly for organisms to acquire and possess. This study investigates possible costs of ornamentation on wolf spider foraging by comparing foraging abilities of two male forms that differ in ornamentation upon maturation. The two male forms, found syntopically in a mixed population in Mississippi, USA, resemble two sibling species: Schizocosa ocreata, in which males develop large black brushes on their forelegs upon maturation, and Schizocosa rovneri, in which males lack ornamentation following maturation. Individuals of both forms participated in foraging trials as penultimates (juveniles) …
Examining The Use Of Terms "Conservation" "Restoration" And "Preservation" Between Natural Resource Professionals And Literature Reviews, Josh Schenk
Department of Environmental Studies: Undergraduate Student Theses
ABSTRACT This thesis will determine if there is a discrepancy between how literature defines conservation, preservation, and restoration, and how natural resource professionals define these terms. Interviews were conducted with six professionals from six different agencies that deal with natural resources. These agencies consisted of both government and non-government groups. In addition to interviewing these professionals regarding how they define the terms, they were asked where their work fits into the context of these terms. The interviewees’ responses were then compared with the literature to determine inconsistencies with the use of these terms in the literature and real world settings. …
Relating Bike Racks And Bike Ridership, John Sens
Relating Bike Racks And Bike Ridership, John Sens
Department of Environmental Studies: Undergraduate Student Theses
Abstract The purpose of this thesis was to investigate the relationship between bicycle ridership and bike racks in a given area. The goal was to discern whether or not the density of bike racks determines the number of riders in the area. I predicted that there would be higher ridership in the areas with a denser bike rack concentration. To investigate this point, I set up five different areas of varying sizes with a similar number of bike racks, and then observed them over a period of 5 business days. By using a simple tally of the bikes found on …

The Economic Feasibility Of Solar Panels For The University Of Nebraska- Lincoln, Chris Schwarz
Department of Environmental Studies: Undergraduate Student Theses
Abstract
The world runs on the electricity provided by gas, oil, and coal. These sources, while cheap, have some major drawbacks associated with them; they are polluting when burned, extraction damages the environment, and the resource reservoirs are limited. With this understanding, the world is turning to renewable energy sources as a means to alleviate its growing energy requirements. But there are problems associated with renewable energy sources preventing them from becoming major sources of electricity generation. These problems are usually monetary in nature.
The cost effectiveness of photovoltaic panels for use by the University of Nebraska-Lincoln as a means …
Cellulosic Ethanol: The Benifits, Obstacles, And Implications For Nebraska, Cassidee Lin Thompson
Cellulosic Ethanol: The Benifits, Obstacles, And Implications For Nebraska, Cassidee Lin Thompson
Department of Environmental Studies: Undergraduate Student Theses
Abstract Ethanol is a biofuel that has unique capabilities to mitigate global climate change by reducing greenhouse gas emissions while simultaneously supporting rural economies and decreasing the United States’ dependence on foreign oil. Currently, the state of Nebraska depends on corn ethanol, which may be unsustainable. Cellulosic ethanol is a promising alternative but it is not without its problems, including high production costs and potential environmental damage. This thesis is an attempt to understand the benefits, downfalls, and processes of corn-based and cellulosic ethanol and the potential implications to Nebraska. This research should shed some light on the current obstacles …
Herbicides And Amphibian Populations, Zach Shirk
Herbicides And Amphibian Populations, Zach Shirk
Department of Environmental Studies: Undergraduate Student Theses
Amphibians are a unique class of species that are found worldwide except Antarctica and Greenland. They range in size from a few millimeters to over six feet long. Amphibian’s habitats are as various as their size, but one thing in common is that amphibians require an aquatic location to breed. Amphibians live in deserts, mountain prairies, rain forest, wetlands, and almost everywhere in between. Amphibians are an integrated part of most natural ecosystems across the world. Amphibians are a critical part of many food chains; they provide the important link between secondary and tertiary consumers. Amphibians are indicator species in …
The Green Revolution Of The 1960'S And Its Impact On Small Farmers In India, Kathryn Sebby
The Green Revolution Of The 1960'S And Its Impact On Small Farmers In India, Kathryn Sebby
Department of Environmental Studies: Undergraduate Student Theses
The Green Revolution was initiated in the 1960’s to address the issue of malnutrition in the developing world. The technology of the Green Revolution involved bio-engineered seeds that worked in conjunction with chemical fertilizers and heavy irrigation to increase crop yields. The technology was readily adopted in many stated in India and for some was a great success. However, there were many farmers who could not afford the inputs necessary to participate in the Green Revolution and gaps between social classes widened as wealthy farmers got wealthier and poor farmers lagged behind. This paper discusses how small farmers were affected …
A Potential Plan Of Action For Emerald Ash Borer In Nebraska, Lee Wheeler
A Potential Plan Of Action For Emerald Ash Borer In Nebraska, Lee Wheeler
Department of Environmental Studies: Undergraduate Student Theses
Abstract Emerald Ash Borer (Agrilus planipennis) (EAB) is an invasive insect pest. It feeds on the cambium tissues of ash tree species. It was first discovered in the United States in 2002 in Detroit, Michigan. Their effects on ash trees are deadly, and it is quickly spreading across the Midwest. Nebraska has not yet been invaded, but confirmed findings continue getting closer and closer. The major problem facing Nebraskans, with regards to EAB, is how to begin preparations to prevent a dramatic economic loss when an infestation does occur. So, to address this problem, I have conducted street and park …
Yellowstone Super-Volcano: Evalutaion, Potential Threats, And Possible Effects On Nebraska Citizens Health And Prosperity, Jennie Korgie
Yellowstone Super-Volcano: Evalutaion, Potential Threats, And Possible Effects On Nebraska Citizens Health And Prosperity, Jennie Korgie
Department of Environmental Studies: Undergraduate Student Theses
Abstract Yellowstone National Park is located over a hot spot under the North American tectonic plate and holds a potentially explosive super-volcano that has the ability to cause deadly consequences on the North American continent. After an eruption the surrounding region would see the greatest devastation, covered by pyroclastic deposits and thick ash fall exterminating most all life and destroying all structures in its path. In landscapes of greater distance from the event the consequences will be less dramatic yet still substantial. Records of previous eruption data from the Yellowstone super-volcano show that the ash fall out from the eruption …
Relatin Dissolved Oxygen Concentration To Fish Distribution In Jarecki Lake, Adam Sutton
Relatin Dissolved Oxygen Concentration To Fish Distribution In Jarecki Lake, Adam Sutton
Department of Environmental Studies: Undergraduate Student Theses
Abstract Water temperature and dissolved oxygen (DO) profiles were measured once every month from mid July to mid February in a relatively deep sand-pit lake in southeast Nebraska. These profiles showed depleted DO concentrations below the thermocline during summer stratification indicating areas fish will likely avoid in summer months. Colder temperatures in fall caused complete mixing of the water column allowing fish to inhabit all depths of the lake. An inverse temperature stratification occurred directly below the ice during winter months as ice cover cooled the surface water to below 4 degrees Celsius. Ice cover also blocked air – water …
A Proposed Plan For Managing Eastern Nebraska's Saline Wetlands, Vandhana Rabadinanth
A Proposed Plan For Managing Eastern Nebraska's Saline Wetlands, Vandhana Rabadinanth
Department of Environmental Studies: Undergraduate Student Theses
Abstract Eastern Nebraska’s saline wetlands play a major role in Nebraska’s environmental place in the world. Besides the role of scientific changes being important, education also is essential in the conservation of these wetlands. Through the observation of Salt Creek tiger beetle (Cicindela nevadica lincolniana) and soil electroconductivity, I propose that we need to reform Nebraska’s education system to help schools play a bigger part in environmental issues such as this one. There is a drastic trend in the correlations between Salt Creek tiger beetle populations and wetland degradation. Since many Lincoln residents have a limited knowledge of what is …

Lead Detection In Water: Using Hydroxyapatite And Atomic Absorption, Nicolas Cantarero
Lead Detection In Water: Using Hydroxyapatite And Atomic Absorption, Nicolas Cantarero
Department of Environmental Studies: Undergraduate Student Theses
Hydroxyapatite is a mineral that is very inexpensive, easily made, and binds well to lead. In this procedure its application will be paired with Flame Atomic Absorption Spectroscopy (Flame AA) to detect lead concentrations in water to ppb levels. While ppb concentrations of lead are too dilute to produce a response from the Flame AA by using Hydroxyapatite to concentrate lead molecules from a larger volume and dissolving the Hydroxyapatite into a smaller volume it may be able to produce a response. The method could provide an inexpensive, efficient, and accurate way to detect lead concentrations to the ppb level …

A Survery Of Western United States Instream Flow Programs And The Policies That Protect A River's Ecosystem, Kyle Jackson
Department of Environmental Studies: Undergraduate Student Theses
The Western United States can best be described as a vast, varying land, with the high plains to the east and the jagged horizons of Rockies to the west. However there is one common trait shared by these states: the lack of water resources. With the continued development of this land, the fact that water is scarce is becoming more real. This issue became more difficult to handle as the public became more aware that many competing uses existed for the finite resource, and those different uses were degrading the natural environments of the surface waters. With this realization instream …
