Factors Perceived By Multifamily Property Owners And Managers As Beneficial In Improving Energy Efficiency, Alex David Arneson

Department of Environmental Studies: Undergraduate Student Theses

Maintaining the existence of affordable housing stock is an important goal for most cities and

communities, as well as at the state and national level. Compared to single-family housing, the multifamily housing sector poses a unique set of challenges and barriers related to investments in energy efficiency. With more than 50 million Americans, many of whom are low income, living in multifamily housing, this sector presents vast opportunities to reduce energy consumption. Reducing our carbon footprint has become an important issue in today’s society. More than ever, there is increased demand to incorporate ‘green’ sustainable design elements and technologies into …

The Effects Of Multilingualism Of Executive Function, Isabella Catalano

Department of Environmental Studies: Undergraduate Student Theses

In today's world, monolingualism is in the minority (Alonso et al., 2017); however, there is still a lack of understanding about the potential effects of being bi- or multilingual, and whether there is an effect of bilingualism in executive function is debated, given multiple contradictory studies (Paap et al., 2015). This study aims to more closely examine whether the number of languages spoken is related to executive function. In this study, sixty-three participants (mean age = 19.9 years, males = 10) completed the Stroop and flanker tasks, measures of inhibitory control, as well as the Language Experience and Proficiency Questionnaire, …

Using The Theory Of Planned Behavior To Understand University Students Recycling Behavior, Vanessa Sonnenfeld

Department of Environmental Studies: Undergraduate Student Theses

Improving recycling behavior is an important means to reducing the ever-increasing amount of waste sent to landfills. When discussing sustainable behaviors, such as recycling, the Theory of Planned Behavior (TPB) can be used to explain why people make the decisions they do. The Theory of Planned Behavior utilizes attitude, subjective norm and perceived behavioral control to be the predictors of behavioral intention. Once we can better explain why students decide to recycle or not to recycle we can utilize this data to increase recycling rates. The Theory of Planned Behavior was used as a basis for this study in order …

Assessment Of Total Suspended Solids And Total Phosphorus Removal By Wetlands And Best Management Practices In Lincoln, Nebraska, Deborah Marik

Department of Environmental Studies: Undergraduate Student Theses

The availability and quality of local surface and ground water, as well as water in the world’s oceans is essential to all. Urbanization brings with it changes in landscape that decreases soils capacity for infiltration of rain, and increase contaminants found in runoff conveyed to surface waters including oceans. Stormwater runoff occurs with small to large size rain events, flowing over a diverse range of impermeable surfaces removing and carrying with it total suspended solids (TSS) and total phosphorus (TP). For these reasons, best management practices (BMPs) were developed, and integrated into existing and future development. The objective is to …

Failing Food Supply: Permaculture's Potential, John Faltin

Department of Environmental Studies: Undergraduate Student Theses

Conventional agriculture is the currently leading production method to grow crops in the western hemisphere. Long-term sustainability of the system and all the components is secondary to producing high yields each growing season, which leads to issues such as erosion and reduced soil quality. Other agricultural production methods such as permaculture aim to build soil and improve quality every growing season. This experiment intends to look at the potential of permaculture to improve soil quality on small-scales at the end of each growing season. The parameters to gauge success are a larger concentration of macronutrients at the end of the …

Companion Planting: Effects Of Radishes On Squash Bugs, Daniel Dejong

Department of Environmental Studies: Undergraduate Student Theses

Throughout history, humans have continuously looked for easier and improved ways of growing our food. Over centuries of hybridizing crop varieties and more recently the invention and implementation of genetically modified (GM) seeds, we have created a food system that is dependent on chemical and seed companies to provide protection from environmental pests. The purpose of this thesis is not to discredit or dissuade someone from using GM seeds, but to take a look at some methods that could protect crops from environmental pests naturally, either for organic farmers or home gardeners. Specifically this review will examine methods of controlling …

How Livestock Production In Eastern Nebraska May Affect Nitrate Concentrations In Platte River, Yuzhe Luo

Department of Environmental Studies: Undergraduate Student Theses

The Platte River is one of the largest rivers in Nebraska and serves as a valuable water source to cities along its watershed. Water is essential for both human life and social and economic development. The human body cannot survive without water for more than 3 days, and many industries require water to function. At a regional scale, the total amount of water is relatively constant, which means if some water sources were contaminated there will be less water available to use.

Land Use As An Indicator Of Stream Habitat Quality In Salt Creek, Adam Brown

Department of Environmental Studies: Undergraduate Student Theses

This study sought to quantify land use types in Lancaster County and identify which, if any, environmental parameters were significantly influencing fish and invertebrate distribution in the Salt Creek basin. Historical sampling data were obtained from the Nebraska Department of Environmental Quality. Watershed land cover maps were created and the percentages of urban/developed, forested, row crop, and grassland use were calculated. This data was combined with NDEQ water quality parameter, fish, and invertebrate sampling data to conduct nonmetric multidimensional scaling. This analysis did not provide significant conclusions about the driving force of fish and invertebrate distribution in this region because …

The Repurposing Of Abandoned Buildings In Gary, Indiana With Sustainable Design: The Revitalization Of A Distressed City, Tatiana Height

Department of Environmental Studies: Undergraduate Student Theses

Abandonment has been a major problem plaguing the city of Gary, Indiana. The city saw its peak in the 1960’s and has since been the site of pollution due to the steel mill, a general lack of investment, and seedy behavior in empty buildings. Based on information gathered, such as the Broken Windows Theory, citizen testimonials, expert interviews, government initiatives, and revitalization plans of other cities, restoring abandoned buildings will prove socially and economically beneficial to the city of Gary. This research provides suggestions for how to mitigate the abandoned building problems, suggestions for possible funding of the abandoned building …

The Effects Of Urbanization On Fear In Wildlife, Sarah Spier, Joseph J. Fontaine

Department of Environmental Studies: Undergraduate Student Theses

Through this study we sought out to determine if Fox Squirrels in Lincoln, Nebraska exhibited a change in response to aerial versus terrestrial predators in urban areas. We addressed the possible consequences that human disturbance has on daily stimuli, predator behaviors, and, in turn, prey behaviors. Specifically, the experiment exposed Fox Squirrels to the vocalizations and visual models of an aerial predator, terrestrial predator, and a control species. Squirrels did not show a significant change in behavior between predator types. However, fox squirrels displayed correct anti-predator behaviors by only responding to the predators and not the control. The time it …

The Restorative Effects Of Natural Decor, Tobias Burnham

Department of Environmental Studies: Undergraduate Student Theses

Humans are continually opting to live in urban environments, furthering us from the innate connection to the natural environment we have evolved with over millennia. These urban settings place several stressors on us in the form of stimuli that requires directed attention (cars, billboards, traffic lights, etc.) in which deplete our attentional resources leading to Direct Attention Fatigue (DAF). Attentional Restoration Theory (ART) is based on the ability of natural environments to have restorative effects on these depleted resources due to the relative ease of experiencing nature through involuntary attention. The focus of this study is to determine how nature-based …

Soil Health After Intense Ponderosa Pine Forest Fire In North Central Nebraska, Amanda Hefner

Department of Environmental Studies: Undergraduate Student Theses

In late July 2012, the Region 24 Complex fire consumed over 76, 000 acres of north central Nebraska. This area consists of ponderosa pine forest with high densities of eastern redcedar, deciduous hardwood forest, and Sandhills prairie. This incredible event provided an occasion to examine the effect of the fire on soil nitrification and soil erosion at The Nature Conservancy’s Niobrara Valley Preserve. Eighteen 900m² plots were established in regions chosen for their topographic location (footslope, midslope, and ridgetop), forest density, and directional slope (north vs. south facing slope). Each plot was split into nine subplots with 25 erosion …

Amphibian Community Composition And Its Relationship To Salinity Along The Salt Creek In Wilderness Park, Lancaster County, Nebraska, Nicholas Arneson

Department of Environmental Studies: Undergraduate Student Theses

Amphibians serve as an indication of proper ecosystem health. Due to their permeable skin and cutaneous respiration, amphibians are prone to be adversely affected by intensified water quality parameters (Welsh and Olliver 1998) . Salinity (the measure of dissolved salts) can have a serious effect on amphibian reproduction and recruitment (Smith et al 2006). A research project was enacted during the 2012 summer field season in Wilderness Park located in Lancaster County, Nebraska to determine if a relationship exists between amphibian species richness and relative abundance with measures of salinity (ppm). Breeding sites were determined and placed in three relative …

Mapping Potential Crp Land And Determining Crp Profitability In Lancaster County, Jamie Pesek

Department of Environmental Studies: Undergraduate Student Theses

Annually 17 tons of soil is lost due to the erosion of agriculture land. A majority of the soil lost is fertile topsoil, which can render the land unproductive. The Conservation Reserve Program (CRP) was enacted to reduce the high erosion rates on agriculture land by giving landowners a monetary incentive to let their land lay idle and allow the soil to regenerate. Although there is awareness of the benefits of CRP, little effort has been put toward delineating CRP eligible land. In this project, Geographical Information Systems were used to map CRP eligible land in Lancaster County, Nebraska based …

The Distribution And Life Cycle Of Alliaria Petiolate In Lincoln, Nebraska, Caleb Pharris

Department of Environmental Studies: Undergraduate Student Theses

Alliaria petiolata (Garlic Mustard) is a biennial alien invasive plant species of the Brassicacea family. It is responsible for displacing native plant species throughout North America and its management has proven to be extremely difficult. Recently several populations of Alliaria petiolata have been discovered in southwestern Lincoln, Nebraska. The spread of Alliaria petiolata is a concern for natural resource managers and the general public. Due to the difficulty of its control, Alliaria petiolata is capable of creating monocultures which diminish the aesthetic value of an ecosystem. While most commonly found in the understory of hardwood forests, it is capable of …

Ecotourism In Costa Rica: Environmental Impacts And Management, Emily Mckeone

Department of Environmental Studies: Undergraduate Student Theses

Globally we are witnessing growing environmental destruction, particularly to the natural resource bases of underdeveloped countries. If ecotourism can generate profits for local economies, while protecting and conserving the natural resource base of that community, it could be a strong alternative for numerous countries. Evidence suggests that the ecotourism industry has been expanding at a rapid rate in recent decades (Dasenbrock 2002). It is important to understand the positive and negative ecological impacts of the industry as this rapid growth rate continues.

The main objective of this study is to highlight the strengths and weaknesses of the ecotourism industry in …

21rst Century Educational Farmstead, Trevis Carmichael

Department of Environmental Studies: Undergraduate Student Theses

When Europeans began settling in the United States, farmsteads were built across the Great Plains. Out of necessity, these had to function in a self-sufficient manner; meaning the people had to produce their own food, use local materials, and be energy efficient for their transportation. Parents had to teach their children how to do all of the practical work it took to maintain their lives. This was the foundation that America was built upon. Having completed the first decade of the 21st century, the time seems right for a mental re-settlement that follows some of those same principles. Teaching our …

Understanding Bioprospecting: Can Indigenous Populations Benefit From The Search For Pharmaceuticals In Areas Of High Biodiversity, Emily Schwindt

Department of Environmental Studies: Undergraduate Student Theses

Bioprospecting is a controversial issue, and anthropologists and other scientists are quick to take sides. The idea of large corporations pumping money into conservation and development programs, while developing what could be the latest life-saving drug simply sounds too good to be true, and often times is. However, if all parties work together and proceed with caution, these benefits could become more than a fantasy. Looking at case studies from Costa Rica, India, South Africa and Panama this paper attempts to find patterns among successful bioprospecting agreements and note shortcomings and identify risks. This information will be used to suggest …

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 …

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.
