Use Of An Alternative Natural Weed Suppressant: Effects Of Parboiled Rice Hull Mulch On The Growth Of Container Weeds, Amy R. Fields-Taylor, Vanessa Slinger-Friedman

The Kennesaw Journal of Undergraduate Research

The Chattahoochee Nature Center (CNC) is one of the leading educational centers in Georgia about the ecology of the Chattahoochee River. Due to lack of man power, keeping down the weeds in the CNC plant nursery is one of those tasks that often gets left undone. The nursery becomes overgrown with invasive weed species. Understandably, they must sometimes resort to the use of herbicides, such as Roundup®, to keep the hundreds of native and endangered species of plants housed at CNC from being choked out by invasive weeds. This study tests the ability to suppress weed growth by use of …

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 …

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.

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 …

Walking As Ontological Shifter: Thoughts In The Key Of Life, Bibi (Silvina) Calderaro

Dissertations, Theses, and Capstone Projects

With walking as ontological shifter I pursue an alternative to the dominant modernist episteme that offers either/or onto-epistemologies of opposition and their reifying engagements. I propose this type of walking is an intentional turning towards a set of radical positions that, as integrative aesthetic and therapeutic practice, brings multiplicity and synchronicity to experience and being in an expanded sociality. This practice facilitates the conditions of possibility for recurring points of contact between the interiority perceived as ‘body’ and the exteriority perceived as ‘world.’ While making evident the self’s at once incoherence with it-self, it opens to a space beyond the …

Acoustic Signatures Of Habitat Types In The Miombo Woodlands Of Western Tanzania, Sheryl Vanessa Amorocho, Dante Francomano, Kristen M. Bellisario, Ben Gottesman, Bryan C. Pijanowski

The Summer Undergraduate Research Fellowship (SURF) Symposium

The Miombo Woodlands of Tanzania comprise several habitat types that are home to a great number of flora and fauna. Understanding their responses to increasing human disturbance is important for conservation, especially in places where people depend so directly on their local ecosystem services to survive. Soundscapes are a powerful approach to study complex biomes undergoing change. The sounds emitted by soniferous fauna characterize the acoustic profile of the landscapes they inhabit such that habitats with the highest acoustic abundance are considered as the most diverse and possibly more ecologically resilient. However, acoustic variability within similar habitat types may pose …

Economic Evaluation Of Coastal Land Loss In Louisiana, Stephen R. Barnes, Craig Bond, Nicholas Burger, Kate Anania, Aaron Strong, Sarah Weilant, Stephanie Virgets

Journal of Ocean and Coastal Economics

Louisiana has lost approximately 1,880 square miles of land over the past eighty years. Projections suggest that in a future without action, the next fifty years could result in the loss of 1,750 additional square miles of land area. As land loss continues, a large portion of the natural and man-made capital stocks of coastal Louisiana will be at greater risk of damage, either from land loss or from the associated increase in storm damage. We estimate the replacement cost of capital stock directly at risk from land loss ranges from approximately $2.1 billion to $3.5 billion with economic activity …

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 …

Elucidating The Effects Of Thiamethoxam Neonicotinoid On Honey Bee Learning Using The Proboscis Extension Response, David J. Shepherd

Undergraduate Honors Theses

In this study, the effects of the neonicotinoid pesticide, thiamethoxam, are examined through the Proboscis Extension Response (PER) in honey bees (Apis mellifera). PER is a form of classical conditioning applied to honey bees through scent and reward association which quantifies learning rates. Results between groups treated with thiamethoxam did not differ significantly from untreated control groups. Potential reasons for these results are discussed. The method and experimental apparatus for testing the PER assay are also discussed.

Trap-Neuter-Return Programs And The Importance Of Associated Public Awareness, Nicolette Sliwa

Biology: Student Scholarship & Creative Works

The focus of this paper is to describe a typical Trap-Neuter-Return (TNR) program and highlight the major pros and cons surrounding this somewhat controversial method of managing the overwhelming free-roaming cat population. The effects of the species’ overabundance on the environment and human health are also discussed. Citing studies completed on TNR programs around the globe as well as mathematical models, the effectiveness of this method is compared to other, currently used alternatives. Finally, it has been suggested that the general awareness level a neighborhood possesses about the true goals of TNR programs has a potentially significant impact on the …

Population Structure Analysis Of Western Painted Turtles, Charrissa Zuerlein

Department of Environmental Studies: Undergraduate Student Theses

Changes in the population structure, specifically the age, size and sex composition, of Western painted turtles can be studied to gain insight into the changes that will occur in closely related endangered species. As species with temperature-dependent sex determination (TSD), the sex ratios of new clutches are affected by climate, and this could cause problems for the species as climate changes occur. This study focuses on fluctuations in the population structure of a single population located near Cedar Point Biological Station in Ogallala, Nebraska. Each summer from 2005-2016 turtles were caught using floating basking traps and hoop nets. Results show …

America's National Parks And The Anthropocene: Addressing The Present To Accommodate The Future In Acadia National Park, Sophie A. Swetz

Honors Theses

In 2000, atmospheric chemist, Paul J. Crutzen, and limnologist, Eugene Stoermer, formally proposed the idea of “the Anthropocene,” a new geologic epoch in which humans are the dominant force shaping the Earth. To claim the Anthropocene's existence is to declare that human actions have altered the Earth in such a way that geologic indicators render it a distinct epoch in the stratification of geologic time. This new epoch emerges as a consequence of increased technological development employed to accommodate an anthropocentric human existence. That is, rapid advancements in technology have driven the transformation from a primarily naturally controlled planet to …

Environmental And Climate Justice Along The Brahmaputra River In Northeast India, Costanza Rampini

Faculty Publications, Environmental Studies

The glaciers of the Himalayas are the source of all of Asia’s major rivers and are crucial to Asia’s water supply, economies, and livelihoods. The Himalayan region is uniquely vulnerable to the impacts of anthropogenic climate change, while also becoming one of the most dammed regions in the world. This case study explores the unequal distribution of the impacts of climate change and dam building along the Brahmaputra River in Northeast India. It examines how the combined impacts of these two processes negatively affect local communities and explores environmental and climate justice issues. In discussing climate change impacts and hydropower …

Testing Predictions Used To Build An Agrivoltaics Installation On A Small-Scale Educational Model, Katie Kinney, Rebecca Minor, Greg Barron-Gafford

STAR Program Research Presentations

Models are valuable tools for explaining and testing systems. Small-scale models can be especially useful for educational purposes. For models to be useful, they have to accurately depict the larger system that they are describing. A novel man-made system, known as an agrivoltaic structure, is being constructed at Biosphere 2 near Oracle, Arizona. The word agrivoltaic is a combination of agriculture and photovoltaics, or solar farming. My research involved creating a small-scale version of this system for educational purposes. The model of this system tested two predictions: that plants will grow better in the shade of a panel and that …

Irrigation Efficiency Of Santa Rosa Island Cloud Forest Restoration Project, Rebecca Bernard, Kathryn Mceachern, Ken Niessen

STAR Program Research Presentations

Beginning in the 1800s, sheep and cattle ranching have caused significant erosion and devegetation of Santa Rosa Island, Channel Islands National Park. In an effort to contain what little soil is left and rebuild the native chaparral, the Cloud Forest Restoration Project is testing erosion control structures such as wattles, leaf litter fences and silt dams. This summer a drip irrigation system was installed along with fog capturing fences to supply water to native plants transplanted near the erosion control structures. As the project has grown, more irrigation has been added to increase the area available for transplanting. This irrigation …

The Influence Of Training On Guides And Their Environmentally Responsible Behaviors And Transformational Leadership Abilities, Nancy Qwynne Lackey

School of Natural Resources: Dissertations, Theses, and Student Research

The ecotourism and interpretive fields were established, in part, to protect natural environments. This goal is achieved by implementing environmentally responsible practices and by providing transformative experiences for visitors. Previous research suggests that ecotour and interpretive guides play a vital role in implementing environmentally responsible behaviors (ERBs) and creating transformative visitor experiences. Other researchers have found that guide training yields many benefits for guides and their abilities, but few have explored the influence of training on guides in detail. The purpose of this research was to explore the influence of established training programs on guides and their ERBs and transformational …

The RDC kitchen facility has staff working around the clock and high consumption electrical, water, and gas appliances constantly running to parallel the high demand. The frequent use of commercial kitchen appliances results in an enormous consumption of energy and water resources leading to comparably high utility bills. Measuring the energy …

Global Worming: A Quantitative Study About Greenhouse Gas Flux In Surface Soils Facilitated By The Anecic Earthworm, Lumbricus Terrestris, Under Rising Global Temperature, Rachel Briden Frei, Jose A. Amador

Senior Honors Projects

Climate change is the long-term alteration in the Earth’s average weather conditions believed to be driven by greenhouse gases (GHG): carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O). These alterations are expected to cause more extreme weather events, gradually warmer global temperatures and greater amounts of precipitation. Roughly 20% of the Earth’s CO₂, one-third of CH₄ and two-thirds of N₂O emissions, originate from soils, and earthworms are known to accelerate GHG. As climate change proceeds, there is expected to be an increase in global temperature of 2-6ºC. Temperature …

There are two types of management strategies that are used in Carson City, NV, which are the free roaming method and the immunocontraception method. Nevada is home to nearly half of the nation’s wild horses (7), and the Departments of Interior and Agriculture need to manage and protect the wild horses that reside on public land stated by the Wild Free-Roaming Horse and Burro Act of 1971 (1). The objectives of this study are to obtain articles about the management of wild horses from previous studies, specifically look at Carson City and the community opinion about the wild horse management …

Environmental Variables Affecting The Performance Of Large-Scale Solar Photovoltaic Power Plants, Parikhit Sinha

Climate Sustainability Lecture Series

The environmental sciences have been critical to identifying global environmental challenges such as climate change, but they have been less extensively utilized in deploying solutions to those challenges, such as solar energy. Environmental variables such as temperature, humidity, aerosols, clouds, soiling, and snowfall have important effects on solar PV performance, and these effects can vary regionally. The current status of large-scale solar PV deployment will be discussed along with the role of environmental variables on PV performance.

Powering The Planet: The Role Chemistry Plays In Solar Energy Technology, Amy M. Scott

Climate Sustainability Lecture Series

Global energy demands are projected to double by 2050, according to the U.S. Department of Energy, and solar energy has the greatest potential as the most benign, universal resource for generating electricity. However, harnessing the solar energy efficiently and converting it towards useful forms of power that are compatible with our current infrastructure remains an elusive goal. Today’s solar energy utilization relies on silicon-based photovoltaic (PV) technology, which converts photon energy to electrical energy. The efficiency of these devices remains low (< 30%) and the cost of processing silicon and installing solar panels in homes makes PV uneconomical compared to the current price of electricity. Research efforts towards developing new inorganic and organic materials for thin film PV to replace silicon are currently underway. Organic materials are particularly interesting from the standpoint of developing simple, cheap materials that can be easily tailored for future PV devices. The future of solar energy utilization relies on developing solar paints for vehicles, solar shingles for rooftops, and spray-on solar ink for small device applications, but continued fundamental research is needed for decreasing cost and improving efficiency for next generation devices.

Ex-Situ Conservation Programs: Worthwhile?, Nicolette Sliwa, Aaron Sieve

Biology: Student Scholarship & Creative Works

The effectiveness of conservation programs was researched, specifically within zoos, and their attempts to repopulate areas with captive-born individuals of endangered species. There are major biological and economic concerns with these programs focused on, including potential genetic adaptation to captivity, effects of inbreeding, and if this is a truly worthwhile use of funds to restore a species. Looking at the black-footed ferret, the whooping crane, and other supposed successful captive-breeding programs, it is explored whether reintroduced individuals thrive in their new habitats sufficiently enough to contribute to the restoration of the species, and more broadly, their ecosystems.

Adaptation On A Budget: How Vietnamese Innovators Are Trying To Design Their Way Out Of Climate Change, Shanti R. Johnson

Graduate Student Theses, Dissertations, & Professional Papers

In the rapidly developing Mekong Delta of Vietnam, young innovators are facing a challenge far greater than simply trying to catch up with the wealthier world. In a growing trend, the next generation of Vietnamese is acting under a common understanding: climate change is real, it’s here and the time to respond is growing short.

For over a decade, Southern Vietnam has consistently been ranked by international organizations like the Intergovernmental Panel on Climate Change as one of the most vulnerable places in the world to the impacts of climate change. That vulnerability is heightened by the fact that the …

The Role Of The State, Multinational Oil Companies, International Law & The International Community: Intersection Of Human Rights & Environmental Degradation Climate Change In The 21st Century Caused By Traditional Extractive Practices, The Amazon Rainforest, Indigenous People And Universal Jurisdiction To Resolve The Accountability Issue, Marcela Cabrera Luna

Master's Theses

Local, national and international conventions that protect indigenous sovereignty and their territories, where many of the resources are extracted from by multinational corporations (MNCs) particularly oil, the number one commodity of the world and cause of climate change, continue to be jeopardized because of the lack of a clear international legal framework that can protect them and potentially hold multinationals accountable for their actions. These practices are causing not only environmental issues to the indigenous and surrounding communities, but climate change is in fact, the real human rights issue of the 21^st century and it affects everyone. By using …
