A Four-Pronged Approach To Addressing A Wild Pig Invasion In A Bottomland And Upland Forested Landscape, Tyler Scott Evans

Theses and Dissertations

Among exotic species that are capable of invading, establishing, and reaching pest status, few pose the range of impacts to biotic (e.g., competition with native species, predation, herbivory, introduction of other exotics) and abiotic (e.g., soil, hydrology) ecosystem components that can be attributed to the wild pig (Sus scrofa). Despite the presence of wild pigs throughout the southeastern United States for centuries, new invasions continue to occur in previously uninhabited and often under-investigated landscapes, including bottomland and upland forests. The recent invasion of the Sam D. Hamilton Noxubee National Wildlife Refuge (hereafter, NNWR) in east-central Mississippi represents an …

Nutrient Optimization For Vegetable Production Under Decoupled Aquaponics Using Brackish Water, Salma Walid Hany Ahmed Abdelfattah

Theses and Dissertations

As the world moves to more sustainable agriculture methods in the agribusiness industry, decoupled aquaponics is recognized as one of the newest techniques currently being utilized to achieve more local food security. As the topic is still freshly new within the industry, a finite number of publications and studies have been made that address the topic hands-on with its many variables. Subsequently, in this paper, an experiment was conducted to assess the most optimized production conditions of both lacinato kale (Brassica oleracea var.palmifolia) and Swiss chard Bright Light (Beta vulgaris ssp. Cicla var. flavescens) plants through the utilization of a …

BASEFLOW VARIABILITY DUE TO CHANGES IN CLIMATE,BASIN CHARACTERISTICS, AND GROUNDWATER WITHDRAWALS IN THE STATE OF WISCONSIN, USA

bySusan Borchardt The University of Wisconsin-Milwaukee, 2022 Under the Supervision of Professor Woonsup Choi

In Wisconsin, the number of high-capacity wells has increased substantially, and concerns have been raised about their impact on both groundwater levels and streamflow. At the same time Wisconsin’s climate has been changing, and both the annual precipitation (5%) and temperature (1.5oC) have been trending upward over the last 68 years and both are predicted to increase into the future. This study attempted to demonstrate the simultaneous effects …

Evaluating Long-Range Transportation Plans For Mainstreaming Of Climate Adaptation Among Virginia Mpos, Sebastian L. Shetty

Theses and Dissertations

Despite the strides made towards addressing climate change through greenhouse gas (GHG) emissions reduction strategies, it has become increasingly apparent that attempting to mitigate the crisis in such a manner alone is insufficient. This thesis joins a growing body of research on how our societies must adapt to a changing climate, contributing more evidence on common barriers to adaptation and how they might be overcome. Through an attempt to evaluate the progress made towards mainstreaming, or integrating, climate change concerns into five Virginia MPOs’ long-range transportation plans (LRTPs), this study provides support for prior hypotheses around the potential for MPOs …

The Flow Less Traveled: Documenting Independent Original Research On Fluid Flow Interactions In The Laurentian Great Lakes And Immediate Surroundings, Thomas F. Hansen

Theses and Dissertations

This work is a compilation of several research projects undertaken by the author. Each research effort identifies a problem that has been addressed traditionally using methods that are significantly costly, to such an extent that, in general, funding, convenience, and practicality are primary limiting factors to their effective implementation. In each case, the author has been able to either build upon existing, less expensive alternatives, or even invent novel approaches. The fundamental recurring research question is, can creative, even novel, computational approaches make more efficient use of resources to interpret or present data in such a way as to make …

An Internatural Communication Study Of Identity Within Nonprofit Animal Shelters, Samentha Emily Sepúlveda

Theses and Dissertations

In a two-part study of this dissertation project, I relied on qualitative research methods to examine the stories of animal shelter employees and volunteers—stories about animal shelters, animal sheltering, and shelter animals—to analyze communication processes that shape staff-identity, organizational-identity, and organizational identification. This project was guided by the communicative constitution of organizations (CCO) approach, which frames communication as not simply something that happens within an organization, but rather argues organization happens in communication. Furthermore, contributing to internatural communication research, this project explored identity and identification from a “more-than human” perspective. Relating CCO and internatural communication to research in this dissertation …

Bottom-Up Understanding Of Informal Settlements: Perspectives Of Urban Slum Dwellers In Nima, Ghana., Bernard Apeku

Theses and Dissertations

More than a quarter of the world’s population lives in informal settlements which house a rapidly growing proportion of the inhabitants of cities in sub-Saharan Africa, such as Accra, Ghana, and in the Global South more generally. However, scholars have shown that the urban planning and urban redevelopment strategies that affect these settlements are top-down in character with minimal resident participation. These prevailing planning and redevelopment strategies are based on the outsiders’ perceptions of informal neighborhoods, rendering them quite inefficient. Therefore, to develop workable policies and strategies that will improve the living condition of informal urban settlers, it is important …

Grief, Loss, And Climate Change: Validation Of A Solastalgia Scale, Claire Luce

Theses and Dissertations

Climate change has been identified as a defining issue of this century (United Nations, n.d.). Climate change impacts human wellbeing including mental health. While much research has focused on the way that the effects of climate change cause increases in common mental disorders, mental health is not just the absence of these disorders (World Health Organization, 2014). Non-pathologized mental health responses to climate change, such as the grief and loss that results from climate change impacts, are a growing consideration for researchers. Solastalgia, or the distress experienced in the absence of the solace once provided by the environment in the …

Can The Circular Economy Concretize Sustainability? A Construal Level Approach To Encourage Sustainable Consumption., Jolie Gutentag

Theses and Dissertations

Despite a growing awareness and understanding of the impact our lifestyles have on the environment, most people have not adequately changed their consumption patterns. One possibility for the disconnect is the perceived abstractness of sustainability. Drawing on construal level theory, this research proposes that framing environmental sustainability as circularity, using the principles of the circular economy, reduces the perceived abstractness of sustainability. Four studies investigate the effects of circular framing on sustainable consumption behavior, including the moderating role of consumers’ chronic level of construal, an innate mindset reflecting a tendency to view information more concretely or abstractly. Findings provide initial …

An Analysis Of Temperate Deciduous Shrub Phenology In Downer Woods, University Of Wisconsin-Milwaukee, Wisconsin, Usa, Chloe Rehberg

Theses and Dissertations

Shrub species, both native and non-native, are an important component of temperate deciduous forest ecosystems but are an often-overlooked and under-studied functional group. Shrubs tend to leaf-out earlier than trees in spring and retain their leaves later in autumn thus extending the overall growing season and the carbon uptake period of the forest ecosystem. In this study, a range of 5- native and 3- non-native shrub species were identified in a deciduous urban woodlot, and the phenology was monitored over a 3-year period on the University of Wisconsin-Milwaukee campus. The aim of this work was to determine any variation in …

A Game Modeling Of A Closed-Loop Supply Chain In A Water-Energy Nexus: Technology Advancement, Market Competition And Capacity Limit, Nabeel Hamoud

Theses and Dissertations

Water and energy are two scarce and concerning resources interconnected in the water-energy nexus. In the nexus, production of energy needs water, and production of water needs energy. For better management of these resources in the nexus, this research considers a supply chain that consists of water suppliers, power suppliers, and consumers of these commodities. In the chain, water suppliers purchase power from power suppliers, and power suppliers purchase water from water suppliers. Other consumers can also buy these resources at the water and power markets. Each firm tries to maximize its own profit. The suppliers of water and power …

The research uses the Koshkonong Locality of southeastern Wisconsin and the Fox/Des Plaines Locality as case studies to compare divergent Upper Mississippian …

Overcoming Disruptions Of Human Adjustment Processes To Ecological Shifts In Revolutionary Burkina Faso 1983-1987: The Inter-Relationship Between Externally Imposed Migration, Coordination Of Ngo Activities, And The Process Of Ecological Renewal Through Land Reform, Robert William Penner

Theses and Dissertations

This paper will explore the Burkinabé revolution and the governmental structure which formed out if it, as an ideological entity with some governing capabilities but not simply a political body as it did not possess the capacities at any time to fully govern the country in terms of the implementation of intended social and economic programs. However, these programs were extremely widespread encompassed swaths of rural society in ways that it had not since the Mossi Empire became centralized and rose to regional prominence in the 18th century. The ideological identity of the revolution in Burkina Faso was not a …

Nature, Identity, And Pastoralism: Changing Landscapes And Shifting Paradigms In The Mongolian Taiga, Jessica Vinson

Theses and Dissertations

The traditional environment of pastoralism is under assault from land degradation, rangeland conservation, and development paradigms that alter the everyday lives of Tsataan Dukha reindeer herders in the Mongolian taiga. This paper seeks to analyze the ways in which identity is shaped through experiences of or relationships with particular nonhuman places and beings, and how the Tsataan Dukha renegotiate their individual and collective identities with changing local landscapes that exert considerable pressures upon the social, political, and economic organization of Dukha life. Senses of place and of space are intimately tied to a sense of self, so disruption in environmental …

Constructing A Data-Based Mortality Profile For Avian Tower Kills At Telecommunication Towers In Illinois, Rachel Dipietro

Theses and Dissertations

During spring and fall seasons, Neotropical migratory passerines travel nocturnally across the Western Hemisphere between their wintering and breeding grounds, often encountering man-made threats. One hazard that has gained considerable publicity in recent decades is the communication tower. While there have been many tower kill studies recorded, there has been no attempt at predicting the risk of towers based on their different attributes (e.g., height, type of light, landscape placement) spatially on a regional scale. The objective of this study was to create seasonal mortality profile maps in GIS for Illinois, based on tower attributes combined with key factors such …

An Investigation Of Daylighting Performance In Sidelit Spaces, Zhe Kong

Theses and Dissertations

The positive influence of daylight on people’s work and well-being has been confirmed in many studies. However, excessive daylight causes discomfort glare, which decreases work productivity, impairs occupants’ vision, and may even cause headaches. Substantial studies explored glare by correlating physical lighting measurements and subjective evaluations. With the development of High Dynamic Range (HDR) image techniques, dynamic changes of daylighting distributions can be effectively captured. Consequently, more studies paired HDR image techniques with subject evaluations to explore glare. However, studies merely relying on field measurements are not only time-consuming and labor-intensive but may also disturb occupants. To address these problems, …

Future Melting Away: Water Stress As A Threat To Human Security In Bangladesh And The Role Of International Community, Farzana Afroz Chowdhury

Theses and Dissertations

Bangladesh is considered as one of the frontline states in the global climate change; its policy agendas attempt to respond to the perceived security threats emanating from such changes. Water stress is one of the key problems the country is facing. Yet, links between glaciers in the Hindu Kush Himalaya, Bangladesh’s climate, growing water stress, and its implications for human security have seldom been studied. Drawing on the concepts of climate change, human security and water stress, the thesis examines the causes of Bangladesh’s freshwater crisis and its contribution to the human insecurity. Here in this study, the influence of …

Agents Of Change: Scholarly Intervention At The Science-Policy Nexus, Daniel Card

Theses and Dissertations

This dissertation examines an emerging “engaged rhetoric of science, technology, and medicine” (ERSTM)—an effort to ensure rhetoric’s “broader impacts” by more directly engaging the practices of science and sociotechnical policymaking. Through careful analysis of engaged rhetorical practice, I identify divergent conceptualizations of both rhetoric and engagement and subsequently draw on new materialist rhetorical theory and empirical research on science communication and public engagement to advance “problem-oriented rhetorical catalysis” (PRC) as a mode of engagement capable of advancing rhetoric’s institutional value and ethical commitments without abandoning its core disciplinary expertise and areas of inquiry. I further suggest the PRC is uniquely …

Impacts Of Drainage Systems On Stormwater Hydrology: Rocky Branch Watershed, Columbia, South Carolina, Logan Ress

Theses and Dissertations

The effects of urbanization and associated land use changes, specifically increases in impervious surfaces, have long been the focal point of urban hydrologic research. However, studies and calculations that consider impervious surfaces alone do not encompass all factors that influence urban hydrologic response. Artificial structures such as storm sewer (SS) systems and road networks increase rates of stormwater conveyance, yet these artificial networks are rarely considered in computations of drainage densities and associated hydrologic alterations. This study examines several hydrologically relevant descriptors that can be used to better understand the impact of urbanization on small watersheds. Rainfall and stormflow data …

Utilizing Natural And Man-Made Resources For Economic Development: What Are The Mechanisms And Why?, Linh Pham

Theses and Dissertations

This dissertation studies the roles of natural resources in determining economic outcomes such as innovation, investment, profitability and economic growth.

The first chapter studies the ease of substitution between energy and other production inputs over time and across countries. Improvements in energy efficiency over the past decades have substantially decreased the amount of energy used per unit of capital. Yet, previous literature often assumes a constant elasticity of substitution between capital and energy. In this chapter, we develop a Solow growth model with a variable elasticity of substitution (VES) between production inputs and show that the long-run growth rate directly …

Death And Destruction: Insight Into The Rhino Poaching Epidemic In South Africa, Richard Wayne Charlton

Theses and Dissertations

The poaching of wildlife has been a concern to many involved in the protection of wildlife. Poaching is found throughout the world and has been around for thousands of years. In the past century, poaching has reached new heights and the concern of an extinction of a species has bought the topic of poaching to new light. Whilst poaching has been seen as a biological or conservation topic in the past, criminologists around the world have now started to delve into the topic. The poaching of wildlife and more so in recent years, rhino poaching, has been a concern in …

A Gis Analysis Of Land Cover Effects On Water Systems: Nutrients And Algae In Stormwater Ponds, Nicole Lee Kappel

Theses and Dissertations

Anthropogenic land conversion is occurring rapidly and has the potential to impact our water quality. This study aims to explore the effect of watershed land characteristics on water quality within stormwater ponds (SWPs). Rapid land conversion is known to affect water quality of receiving water bodies, however not much is known about the effect of urbanization on SWPs. Geographic informational systems (GIS) was used to determine areas of land that drain into ponds. Water samples were collected and analyzed for total phosphorous, dissolved reactive phosphorous, nitrate, and ammonia. Algal pigment and percent cover measurements were taken in the field and …

An Integrated Environmental Analysis Framework For Multi-Functional Urban Food Production Utilizing Nutrient Recycling From Organic Waste Streams, William Kort

Theses and Dissertations

Increasing enthusiasm for local food, including urban agriculture, has piqued research interest in the tenets underlying perceived benefits of localizing food production. This study develops and demonstrates the application of a comprehensive framework for the life cycle environmental assessment of the utilization of urban organic wastes in urban agriculture, specifically fruit and vegetable production. Results indicate that this full “urban nutrient cycle” may have significant environmental benefits in terms of land area requirements, water use, wastewater generation, nutrient recovery, environmental contamination and green infrastructure potential, compared to more conventional methods of waste processing and food production. Urban intensive food production …

Neurobehavioral And Gene Expression Effects Of Early Embryonic Methylmercury Exposure In Yellow Perch (Perca Flavescens) And Zebrafish (Danio Rerio) Larvae, Francisco Xavier Mora Zamorano

Theses and Dissertations

Methylmercury (MeHg) is a pervasive and persistent neurotoxic environmental pollutant known to affect the behavior of fish, birds and mammals. The present study addresses the neurobehavioral and gene expression effects of MeHg in yellow perch (Perca flavescens) and zebrafish (Danio rerio) embryos. The rationale for this study originated from an interest to understand the behavioral and molecular phenotypes of environmental MeHg exposure in the yellow perch, an ecologically and economically relevant species of the North American Great Lakes region. Both MeHg and the yellow perch coexist in a common ecosystem: the North American Great Lakes. However, the effects of this …

Using Spatiotemporal Methods To Fill Gaps In Energy Usage Interval Data, Kristin K. Graves

Theses and Dissertations

Researchers analyzing spatiotemporal or panel data, which varies both in location and over time, often find that their data has holes or gaps. This thesis explores alternative methods for filling those gaps and also suggests a set of techniques for evaluating those gap-filling methods to determine which works best.

Estimating Stormwater Runoff For Community Gardens In New York City, Mara Gittleman

Theses and Dissertations

While much of the literature cites community gardens as providing urban ecosystem services, there is very little research quantifying these benefits. This thesis compares the stormwater runoff rates of urban vacant lots, community gardens, and residential developments in New York City and evaluates community gardens as green infrastructure.

The Impact Of International Water Treaties On Transboundary Water Conflicts: A Study Focused On Large Transboundary Lakes, Victoria Eileen Lubner

Theses and Dissertations

Lakes are the largest reservoir of available surface freshwater on Earth, representing an irreplaceable ecosystem, essential for all life. Despite the crucial need for these lakes, there has been minimal research focused on their health and security. There are over 1,600 transboundary lakes worldwide, which do not follow political borders and thus result in governance and management challenges. International water treaties have been cited to be a main mechanism for cooperation between riparian countries. This study researches the impact of international water treaties as well as economic, political, and environmental variables on transboundary water conflict between riparian countries of the …

Perceptions Of Bike Sharing In Underserved Communities Within Milwaukee And The Twin Cities, James Hannig

Theses and Dissertations

Despite becoming increasingly more popular in cities across North America, many bikeshare systems have received criticism for not reaching minority and low-income populations. Several bikeshare operators have implemented measures to reach these populations including removing financial barriers, placing stations in underserved neighborhoods, and partnering with various community organizations. However, until recently, few have explored how people in these underserved areas perceive bike sharing.

Feedback was solicited from key community partners in Milwaukee, Wisconsin and Minneapolis/St. Paul, Minnesota to better understand how bike sharing is perceived in underserved communities and to determine whether other models could better address the transportation needs …
