Collective Drip: Transformation, Hybridity, And Queer Ecologies, Vee Adams

LSU New Orleans Theses and Dissertations

In my recent body of work, Collective Drip, I investigate the queer and trans body as a site for transformation. Through the lens of queer theory, ecology, and myth, I explore what it means to be becoming, always in process. Looking at hybrid bodies and symbiotic life forms, I’m interested in investigating what it means when the body is seen as a dynamic landscape? What happens when the community is reinvisioned as an ecosystem? Facing the current transphobic political landscape, this body of work offers queer and trans visions of pleasure and abundance.

Adapting To Climate Change: Outdoor Recreation Impacts In New Hampshire, Visitor Coping Behaviors, & Provider Management Strategies, Madeleine Smith

Doctoral Dissertations

As of 2023, outdoor recreation participation in the United States (U.S.) reached a 15-year high, generating $1.2 trillion in economic output and supporting 5 million jobs. Concurrently, the contiguous U.S. experienced earth surface temperatures averaging above the 20th-century norm for the 27th consecutive year. Climate change presents increasing challenges for outdoor recreation, particularly in the Northeast and North Central U.S., where seasonal shifts, extreme weather events, and resource degradation are projected to acutely impact recreation patterns and management needs. New Hampshire (NH), where nearly 30% of the state is safeguarded for public use, relies heavily on outdoor recreation. As of …

Railroads And Recreation In Minnesota, Carter Versaevel

Celebrating Scholarship and Creativity Day (2018-)

This map shows outdoor recreation areas along with the most populated cities and all railroads in Minnesota. I wanted to find out what areas were most in need of outdoor recreation opportunities and how to provide those opportunities. I found that railroads and high population cities were concentrated together. These areas had little access to outdoor recreation. These railroads can be turned into trails to provide much-needed recreation to a large number of people. I created this map using data I acquired through a formal request to the Minnesota Department of Transportation. I used the Minnesota Department of Natural Resources’ …

Exploring Variability Factors In Bur Oak Morphology, Karyn Morrissey

Celebrating Scholarship and Creativity Day (2018-)

This project, completed for Dr. Kate Cary in the Biology department, investigates how bur oak (Quercus macrocarpa) leaf morphology varies geographically. Using digitized herbarium specimens and provided data which included latitude, longitude, collection moth and year, leaf dissection, petiole length, temperature, and precipitation, the project visualizes patterns in morphology with a focus on leaf dissection (cm). Maps were generated both at the state level (Minnesota) and national level, depicting bur oak locations and morphology trends across different seasons (January-May and June-December) over the past century.  The importance of this data lies in its ability to reveal how environmental factors like …

Fish Need Shelter Too! The Importance Of Mangroves In An Aquatic Ecosystem, Karyn Morrissey

Celebrating Scholarship and Creativity Day (2018-)

Mangrove trees exhibit many adaptations to living in salt water and tend to be found along marine shores. Some of these features include the ability to have their roots constantly submerged in water and stilt roots. Stilt roots are not true roots, instead they grow from the stem to the ground and provide both height and mechanical support in a somewhat fluid soil that the plants grow in. These stilt roots are thought to provide sanctuary for many juvenile fish. During our time on San Salvador Island, Bahamas (March 2025), we hypothesized that there was a relationship between distribution of …

From Self To Society: How Threat Type And Message Mode Affect Environmental Intentions Among Young Audiences, Lucas Vogt

Electronic Theses and Dissertations

This study examined the influence of threat type (personal vs. societal) and message mode (narrative vs. utilitarian) on young adults’ environmental intentions. Using the extended parallel process model (EPPM), this study argued for expanding the theory to include threat type (societal vs. personal) to clarify how threat is understood. A 2 x 2 factorial design was utilized to test the effects of threat type and message mode on environmental behavioral intentions. A sample of 266 university students participated in an online survey. Based on prior research, this study hypothesized that personal threats would yield the highest levels of environmental behavioral …

Sediment And Debris Flows Resulting From The 2020 El Dorado Wildfire, San Bernardino Mountains, California, Andrew Suarez

Electronic Theses, Projects, and Dissertations

The Yucaipa Ridge is a section of the San Bernardino Mountains within the Transverse Ranges of Southern California. During the summer and early fall of 2020, Yucaipa Ridge experienced severe vegetation damage from both the Apple and El Dorado wildfires. Burned slopes exhibit a higher susceptibility to geomorphic change within several years of burning from the introduction of meteoric water onto the slope. Yucaipa, Oak Glen, and other nearby communities are currently at risk of damage by hyperconcentrated flows and debris flows during the seasonal rainy season.

Debris flows and hyperconcentrated flows (a.k.a. mudflows; are grouped and referred to in …

The Impact Of Green Credit Ratio On Return On Assets, Liao Wang

All Theses

How does the green credit ratio affect a bank return on assets? This study uses panel data from 2012 to 2019, covering 18 large banks in China, including 6 state-owned banks and major 12 important joint-stock and city commercial banks. I use regression models to measure the effect of the green credit ratio (GCR) on return on assets (ROA) and return on equity (ROE), and we focus on how bank ownership and fixed effects matters.

The results show that the effect of green credit ratio (GCR) on ROA depends on the model design. When bank fixed effects are included, green …

The Proverbial Milk And Honey: Frontier, Racial Lines, And The Development Of California Foodways, Ahlys Gandara

Electronic Theses, Projects, and Dissertations

This thesis proposes that the development of foodways in the state of California occurred concurrently with the development and failures of Americanization and the American frontier. This is done with respect to the fact that California has a much longer history than that of the United States. While foodways are often discussed and examined within the ideas of nationalization, this becomes harder to do within the United States as there is no unifying idea of a national identity and any attempts to do so were hampered by the lack of consensus as to a singular identity. This is especially true …

Private Conservation And Indigenous Groups With Contested Identities: How Are Land Trusts Navigating Recognition Politics And Controversy?, Geneva Nuttall Lish

Master's Theses and Capstones

New Hampshire has no state or federally recognized Indigenous tribes, and the identities of its self-recognized Abenaki tribes have been publicly contested by Canadian scholars and the Odanak and Wolinak First Nations. As a result, conservation practitioners within New Hampshire land trusts face challenges in making decisions about collaborations, cultural access, and land management involving tribal entities. Our research thus explores how land trusts currently incorporate Indigenous relationships in their operations, and how these practices may be affected by (a) an absence of tribal federal recognition and (b) the publicly contested nature of a tribe. We conducted six semi-structured interviews …

High Frequency Analysis Of The Carbon Dioxide Linkage Between Terrestrial And Aquatic Ecosystems, Amanda G. Theall

Master's Theses and Capstones

Carbon dioxide (CO2) is a potent greenhouse gas, and surface water concentrations are often supersaturated relative to the atmosphere. To fully quantify CO2 dynamics in stream ecosystems, it is critical to understand sources of stream CO2, particularly the link between terrestrial and aquatic ecosystems. It is unclear how soil CO2 enters streams and to what magnitude. To address this knowledge gap, I analyzed high-frequency CO2 time-series of soil and stream water sensor data to understand source-sink dynamics and time lags between the two pools. I used seven years of hourly sensor data from three soil depths with upscaled 15-minute stream …

Post-Fire Debris Flow Initiation Potential Based On Forensic Analysis Of Debris Flow Occurrence From The 2020 El Dorado Wildfire On Yucaipa Ridge, San Bernardino County California, Seth Clemen D. Saludez

Electronic Theses, Projects, and Dissertations

This study focuses on the potential debris flow initiation and effect in areas affected by the El Dorado Fire in the Southern San Bernardino Mountains. It uses novel technology combining drone-based photography and LiDAR imaging to create surface models of areas where potential debris flows could initiate, flow, and be deposited. The scans were repeated as geomorphic change occurred through the wet season to document spatial and volumetric changes resulted from the flows. These measurements were combined with traditional fire assessment and observational methods to characterize pertinent conditions.

As we investigated potential debris flow risk in this study area, we …

The Human Legacy: Agriculture, Civilizations, Strife, And Pandemics Changing Our Climate, Jacalyn M. Wittmer Malinowski

Climate Change and the Individual, 2025-26

For most of human history, climate has shaped our lives, while our influence on it remained minimal. However, the notion that early humans had no measurable impact on the climate before industrialization is inaccurate. Early in human history, activities – such as the rise of agriculture, the growth of civilizations, periods of conflict, and pandemics – altered greenhouse gas levels in the atmosphere. These changes contributed to significant periods of climate change long before the burning of fossil fuels set us on the path to today’s global climate crisis.

Advancing Marine Animal Movement Studies Using An Open Innovation Framework, Jacob Levenson

Graduate Doctoral Dissertations

This dissertation investigates the application of open innovation to migratory marine animal movement studies, addressing critical challenges in understanding, managing and ultimately conserving highly mobile and migratory species (HMMS). The species examined herein, including manta rays, sea turtles, and marine mammals, face threats including habitat disruption and behavioral changes to adapt to anthropogenic stressors. Traditional monitoring techniques, while valuable, are often costly, limited in scale, and protected by proprietary intellectual property, all of which decrease accessibility. Ambitious conservation goals, such as protecting 30% of the ocean by 2030, require more data that are indubitably sharable and thus will need to …

Per- And Polyfluoroalkyl Substances In A Suburbanizing Watershed, Bailey Mullins

Master's Theses and Capstones

Per- and polyfluoroalkyl substances (PFAS) are persistent man-made chemicals that accumulate in aquatic environments due to their widespread industrial and commercial use and resistance to degradation. Understanding their spatial distribution and relative abundance in streams draining suburbanizing watersheds is crucial for effective watershed and water quality management. This study investigates how the concentrations and composition of PFAS in surface water and sediment are impacted by urbanization. PFAS were quantified in the Lamprey River watershed, a coastal watershed in southeastern New Hampshire that is experiencing ongoing suburbanization. Sampling sites include tributaries, mainstem, and estuarine areas. Surface water, sediment, and well water …

Finer Resolution Paleoclimatological Network Analysis Of Hydrological Extremes And Tree-Growth Response For Kentucky, U.S.A., Jordan Sharp

Electronic Theses and Dissertations

As climate change accelerates, southeastern states like Kentucky face increasing environmental and economic challenges. To improve future climate predictions, this study enhances paleoclimate reconstructions with a high-resolution tree-ring network for Kentucky, combining data from both living trees and dendroarchaeological sources. I evaluated the climate sensitivity of tree growth using superposed epoch analysis, static correlations, and spatial field correlations in KNMI Climate Explorer, along with moving correlations against seasonal temperature and moisture variables. Findings reveal that white oak and tulip poplar exhibit significant drought sensitivity across both live and archeological sites. However, I observed a weakening relationship between tree-ring growth and …

Photochemical Transformations Of Crude Oil In Marine Environments: Temporal And Thermal Dynamics Of Oxygenated Photoproducts And Genotoxic Effects, Mohamed Elsheref

LSU New Orleans Theses and Dissertations

This dissertation investigates the photochemical transformation of different crude oil types in marine environments, focusing on the time and temperature dependency of the formation of oxygenated photoproducts and their potential genotoxic effects. Using electrospray ionization tandem mass spectrometry (ESI-MS/MS), we examined the time and temperature dependence of aldehyde and ketone oxocarboxylic acid photoproduct generation from crude oil-seawater systems under simulated solar irradiation. The study revealed a near-linear increase in photoproduct concentration over an 18-hour irradiation period, with production rates ranging from 0.6 to 69 µmol/hm² of oil surface. Temperature effects on photoproduct formation were complex, but generally showed increased total …

Game Changing Education: Empowering High School Stem Teachers To Teach Engineering Using Games, Leslie Brown

All Graduate Theses and Dissertations, Fall 2023 to Present

In response to the Next Generation Science Standards (NGSS) released in 2013, there was a nationwide push for K-12 schools to include engineering concepts in science classrooms. However, there is an overall lack of teacher preparedness and training towards engineering topics as shown by common engineering misconceptions. To improve this issue, I initiated a qualitative study to describe the strategies and attitudes of high school science, technology, engineering, and mathematics (STEM) teachers that have implemented game-based, engineering activities into their classroom. Game-based learning is an instructional framework that utilizes game-like elements in a classroom and was used in this study …

"Once Our Land Is Gone, It's Gone": Farmer Perspectives On Growth, Embeddedness, And The Future Of Food In The Great Salt Lake Basin, Bryn Noelle Watkins

All Graduate Theses and Dissertations, Fall 2023 to Present

The Great Salt Lake Basin hosts a knot of intensifying pressures on agriculturalists—including economic constraints, as even arable land is increasingly valuable for development, and ecological constraints, as aridification and climate change affect the conditions in which food can grow. Given the unique relationship farmers have with the land as its modern-day stewards, their perspectives on the nature and consequences of these pressures offer profound insights into how the region might responsibly navigate its resource management and food systems moving through the future. In the first paper, I draw upon 15 interviews with commodity farmers to understand their experiences with …

The Desert Shall Rejoice: Lds Relational Values And Multispecies Justice In The Intermountain West, Sarah A. Woodbury

All Graduate Theses and Dissertations, Fall 2023 to Present

In the American West, climate change is shifting weather and climate patterns in ways that may dramatically change lands, livelihoods, and communities. In the face of these threats, conservationists and local communities must work collaboratively to ensure that environmental and human communities are healthy enough to weather approaching shifts. Church of Jesus Christ of Latter-day Saint (LDS) values, practices, and histories strongly influence the Intermountain West, yet there is little research on LDS environmental values and perceptions. This study seeks to answer questions that work in this gap. It documents the knowledge and values of communities in the Intermountain West …

Thermal Biology Of The Eastern Treehole Mosquito Aedes Triseriatus (Diptera: Culcidae) And Other Vertivorous Dipterans, Kelly I. Zimmerman

Theses, Dissertations and Culminating Projects

Temperature plays a critical role in mosquito life cycle, behavior, and other ecological interactions. My dissertation analyzed how temperature affects egg hatch rates of the eastern treehole mosquito (Aedes triseriatus) and how amino acid substitutions in TRPA1 correlated with host finding through thermotaxis and the convergent evolution of vertebrate feeding/utilizing in Dipterans. As ectotherms, embryonic development and egg hatch rates are directly influenced by the water temperature mosquito eggs are oviposited into. Ae. triseriatus eggs do not hatch all at once, to avoid potentially high larval mortality rates due to their non-static oviposition sites. They engage in staggered egg hatching, …

Life Cycle Analysis Of Cosmetic Products -- Assessing Environmental Sustainability And Potential Impacts, Karina Magro Machado

Theses, Dissertations and Culminating Projects

Framing environmental justice through the lenses of distributive and data justice, the project explores both the promises and pitfalls of using emergent data sources to enhance the spatial and temporal precision of environmental equity investigations. Through a combination of systematic literature review, spatial analysis, system dynamics simulation, and policy evaluation, …

Tracking Fall Migration With The Motus Wildlife Tracking System: The Fate Of Window-Struck And Captive-Raised Passerines, Cailin O'Connor

Theses, Dissertations and Culminating Projects

Many species of North American passerines migrate along the Atlantic flyway in the fall to reach winter habitats in the southeastern United States, the Caribbean, and Central and South America. Birds face many perils along their journeys including window strikes, which kill over one billion birds per year in the United States alone. Some birds survive the impact and may continue their migration. These birds may suffer delayed mortality or show aberrant migration due to injuries. This research seeks to understand if window-struck birds that initially survive bird-building collisions survive into the future and, if so, if they migrate effectively. …
