How Are The Torres Strait Islander's Traditional Hunting Practices Affected By The Current Rate Of Decline In Dugong And Sea Turtle Populations And The Australian Government's Co-Management Policies On Marine Preservation?, Katilyn Price
Department of Environmental Studies: Undergraduate Student Theses
This paper will attempt to identify the extent to which the Torres Strait Islanders traditional hunting practices have been disrupted by the overall decline in dugong and sea turtle populations, which has directly correlated to an increase in hunting restrictions put in place by the Australian Government. The traditional hunting of dugongs and sea turtles provides not only a food source, but brings prestige to the men who catch them and serves as an educational platform to teach the younger generations about their culture. There are many environmental threats that impact the populations of sea turtles and dugongs though the …

The human oral cavity contains a number of different habitats, including the teeth, gingival sulcus, tongue, cheeks, hard and soft palates, and tonsils, which are colonized by bacteria. The oral microbiome comprises over 600 prevalent taxa at the species level, with distinct subsets predominating at different habitats. The oral microbiome has been extensively characterized by cultivation and culture-independent molecular methods such as 16S rRNA cloning. Unfortunately, the vast majority of unnamed oral taxa are referenced by clone numbers or 16S rRNA GenBank accession numbers, often without taxonomic anchors. The first aim of this research was to collect 16S rRNA gene …

Interior Design Program: Student Creative Activity
This thesis examines the ability of the sustainably designed building to alter occupant behaviors using LEED for New Construction and Major Renovation, Green Building Rating System™ as a standard of measure. A cross sectional survey compares the pro-environmental behaviors, intentions, environmental knowledge, and pro-environmental orientation of occupants working in a traditionally designed building and occupants working in a LEED-NC certified building located on the University of Nebraska - Lincoln Campus. While there is a visible increase in the pro-environmental variables for occupants working in the sustainable environment, data analysis indicates that these differences are not statistically significant for any of …
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 …
Fire Effects On Wildlife In Tallgrass Prairie, Maria Gaetani, Kayla Cook, Sherry Leis
Fire Effects On Wildlife In Tallgrass Prairie, Maria Gaetani, Kayla Cook, Sherry Leis
United States National Park Service: Publications
Abstract
In the tallgrass prairie region of North America, grasslands are often burned on a rotational schedule to prevent the encroachment of woody species and maintain the vigor of plant communities. Although prescribed fire practitioners often consider the effects of fire on plant communities, the effects of fire on wildlife are also important. Practitioners as well as park visitors inquire about the effects of fire on birds, deer, and other animals of interest. Many wildlife species focus on vegetation structure in choosing suitable habitats, and fire can temporarily alter that structure. Wildlife species have varying habitat needs, and therefore, a …
Global Trends In Private Protected Areas And Their Implications For The Northern Great Plains, Jeff Langholz
Global Trends In Private Protected Areas And Their Implications For The Northern Great Plains, Jeff Langholz
Great Plains Research: A Journal of Natural and Social Sciences (through 2013)
Like many parts of the world, the Northern Great Plains faces immense challenges to sustainable land use. Privately owned conservation areas have emerged as a potential solution. This article reviews five global trends in so-called private protected areas and discusses their implications for the Northern Great Plains. The trends point to five recommendations to the Northern Great Plains community: (1) act now to tap rapidly growing policy support; (2) combine many models, including private protected areas that are owned by individuals and groups, formal and informal, large and small, and are dedicated to strict protection as well as sustainable use; …
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 …
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) …
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 …

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. …
Yellowstone Super-Volcano: Evaluation, Potential Threats, And Possible Effects On Nebraska Citizens Health And Prosperity, Jennie Korgie
Yellowstone Super-Volcano: Evaluation, 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 …

An Artesian Well System In Beaver Crossing, Nebraska, It's Development And Demise, Mary Lanik
Department of Environmental Studies: Undergraduate Student Theses
ABSTRACT
Nebraska has a veritable wealth of groundwater. The High Plains Aquifer underlies most of the state, and within its sand and gravel deposits, many interconnected aquifers provide fresh water for a variety of uses.
One of the most spectacular examples of this resource is the artesian well. Beaver Crossing, Nebraska was once home to one of the most prolific artesian systems in the state before its demise. Founded in the 1880’s, Beaver Crossing soon became known for its many artesian wells, that provided leisure activities and supported profitable business ventures such as small farming, ice production and aquiculture. Eventually …

Cellulosic Ethanol: The Benefits, 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 …
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 …
Distribution Of Dioecious Eastern Red Cedar (Juniperus Virginiana) Along An Environmental Gradient In Ogallala, Ne, Taylor Sloey
Distribution Of Dioecious Eastern Red Cedar (Juniperus Virginiana) Along An Environmental Gradient In Ogallala, Ne, Taylor Sloey
Department of Environmental Studies: Undergraduate Student Theses
Abstract
The purpose of this research was to study the sex distribution and energy allocation of dioecious Eastern Red Cedars (Juniperus virginiana) along an environmental resource gradient. The trees surveyed were growing in a canyon located at the University of Nebraska’s Cedar Point Biological Research Station in Ogallala, Nebraska. Due to the geography of this canyon, environmental factors necessary for plant growth should vary depending on the tree’s location within the canyon. These factors include water availability, sun exposure, ground slope, and soil nitrogen content, all of which are necessary for carbon acquisition.
Juniperus virginiana is a dioecious conifer. Dioecious …
Cattle Ranching And Biodiversity Conservation As Allies In South America’S Flooded Savannas, Almira Hoogesteijn, Rafael Hoogesteijn
Cattle Ranching And Biodiversity Conservation As Allies In South America’S Flooded Savannas, Almira Hoogesteijn, Rafael Hoogesteijn
Great Plains Research: A Journal of Natural and Social Sciences (through 2013)
Cattle ranching in Latin America supports wildlife conservation. Ranching probably represents one of the few land uses in which we can advance conservation goals. The approximately 950,000 km2 of Bolivian, Brazilian, Paraguayan, Colombian, and Venezuelan savannas that are privately owned and dedicated to meat production provide a model for conservation programs. We present a geographic and historical description that covers several centuries and ends with descriptions of seven successful cattle ranches (three in the Venezuelan Llanos and four in the Brazilian Pantanal) where cattle ranching, ecotourism, and wildlife conservation coexist. These three activities support each other: tourism creates additional income …
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 …

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 …

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 …

Revised Relative Abundance Estimates And Temporal Activity Of Bats At Three Great Lakes National Parks Based On Acoustic Data, Bruce W. Miller
Revised Relative Abundance Estimates And Temporal Activity Of Bats At Three Great Lakes National Parks Based On Acoustic Data, Bruce W. Miller
United States National Park Service: Publications
Abstract
In this study, Miller re-analyzed acoustic bat data collected from June-August 2003 that was part of a baseline inventory of bat species in three national parks in the Lake Superior region. While the original study presented base-line data on the presence/absence of bat species in these parks, this reanalysis provides estimates of relative abundance and temporal activity of the identified species. Using a suite of recently developed acoustic analysis tools, Miller created species specific filters. This allowed parsing of calls from non-fragmented sequences and differentiate between two species, Myotis septentrionalis and Myotis lucifugus, that were combined into a …
