Analysis Of Lava Flow Paths Using Remote Sensing And Geomorphological Techniques, Oluwatosin Oluyemisi Ayo

Dissertations, Master's Theses and Master's Reports

Lava flows have severe impacts on the Earth’s surface, communities, and natural habitats. Accurate modeling of lava flow paths is crucial for volcanic hazard assessment and risk mitigation. This research integrated remote sensing, geographic information systems, geomorphological techniques, and hydrologic analysis to numerically determine the optimal ground sample distance (GSD) of digital elevation models (DEMs) for delineating lava flow paths. Two volcanic regions were analyzed: the Afar Region of Ethiopia (Alu, Dalaffilla, and Erta Ale volcanoes) and the Reykjanes Peninsula of Iceland (Fagradalsfjall volcano). Forward and backward modeling methods were used to simulate potential lava flow paths. Remote sensing data, …

Partisan Divides In Environmental Spending Attitudes: A Two-Level Hierarchical Analysis, 1973-2022, Jordan Lipner

Honors Undergraduate Theses

Public attitudes toward environmental spending have become increasingly divided along party lines, with sharp shifts over the past five decades. This thesis updates and expands on Johnson and Schwadel’s 2019 study by applying a two-level hierarchical linear model to General Social Survey data updated to include data from 2015-2022, capturing how political affiliation, education, race, and economic context interact with broader political and economic contexts to shape environmental attitudes over time.
The results show that political affiliation remains the strongest and most reactive predictor of environmental spending attitudes. Republican respondents are significantly more likely to oppose environmental spending, especially under …

A Depth-Integrated Investigation Of Hydrodynamic Habitat Preferences Of Seagrass In Estuarine Environments, Madison Giuntoli

Graduate Thesis and Dissertation post-2024

Submerged aquatic vegetation shapes morphodynamic, hydrodynamic, and ecological attributes of shallow, coastal waters. Though seagrasses have been shown to exhibit threshold tolerances in response to varying light, salinity, and temperature, hydrodynamic thresholds have yet to be described. In this study, seagrass distribution data observed over 25 years were combined with modeled wave energy to quantify the hydrodynamic preferences of seagrass. The frequency distributions of wind-wave heights in the study area (Mosquito Lagoon, Indian River Lagoon, and Lake Worth Lagoon, Florida) were characterized using the Simulating WAves Nearshore (SWAN) numerical model. Seagrass distribution data, collected through direct observation and aerial imagery …

Everglades Restoration: Interdisciplinary Analysis And Pluralist Approaches, Sarah Swiersz

Graduate Thesis and Dissertation post-2024

This study uses interdisciplinary methods to analyze ecological restoration of the Florida Everglades (Everglades Restoration). Everglades Restoration is considered one of the largest ecosystem restoration projects in the world, relying on complex intergovernmental and sociopolitical relationships. Framing Everglades Restoration as a quintessential “wicked problem”, a problem that is inherently complex and unsolvable, provides grounds for interdisciplinary analysis. This study analyzes two epistemological approaches to Everglades Restoration: Western-scientific knowledge, the epistemological foundation of Everglades Restoration, and Indigenous Traditional Ecological Knowledge, which challenges the foundations of Everglades Restoration. Interdisciplinary analysis within a decolonial framework identifies limits to integration of knowledge, a core …

Efficacy Of Salmonella Surrogate Enterococcus Faecium In Poultry And Mash Broiler Feed, Corey Waitman Coe

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation investigates the efficacy of Enterococcus faecium as a surrogate for Salmonella in validating thermal inactivation processes during poultry feed manufacturing and meat processing. The research encompassed three studies evaluating microbial kinetics in mash broiler feed, reconstructed ground chicken, and predictive modeling approaches to improve food safety interventions. In the first study, the thermal resistance of nalidixic acid-resistant Salmonella Typhimurium and E. faecium was compared in mash broiler feed heated at 75–95°C. Results demonstrated that E. faecium exhibited significantly greater heat resistance than Salmonella, with longer shoulder times, greater tailing effects, and higher D-values, supporting its use as …

Vital Rates And Nest Site Selection Of Merriam’S Wild Turkeys (Meleagris Gallopavo Merriami) In South-Central, South Dakota, Luke N. Mccray

Graduate Theses, Dissertations, and Problem Reports (ETD)

Wild turkeys (Meleagris gallopavo) are an economically and culturally significantly game species throughout much of the United States. Within South Dakota, spring turkey hunting generates approximately $20 million in expenditures annually to local economies. Merriam’s wild turkeys (Meleagris gallopavo meriami) were reintroduced to the Missouri River Breaks of Gregory County, South Dakota, USA, between the 1950s and 1980s, and was one of the most successful reintroductions in the state. However, a recent decline in gobbler harvest suggests a potential decline in this population. To estimate survival and reproduction and evaluate nest site selection, we captured 121 …

Jurnal Ekonomi dan Pembangunan Indonesia

This study aims to assess Indonesia’s readiness to implement carbon trading in 2025 to achieve net zero emissions by 2060. The research uses a mixed-method approach, combining literature review, multivariate linear regression, and Vector Error Correction Model (VECM). The results indicate that the Human Development Index (HDI) has a negative and significant impact on CO2 emissions in the long term. This impact is greater than the results observed in Singapore and Thailand. With established policies and a demographic bonus in 2045, optimizing human resources is crucial for achieving net zero emissions by 2060.

Exploring The Role Of Government Funding And Policy Criteria In Greening Projects: A Case Study Of Southside Richmond, Destiny R. Brown

Master of Urban and Regional Planning Capstone Projects

This thesis explores how government and private funding structures and policy criteria influence community-based organizations (CBOs) engaged in urban greening projects, focusing on Southside Richmond, Virginia through a case study of a local CBO. Using a multi-method approach including document analysis, secondary data review, and autoethnographic reflection, the research suggests a gap between visibility and influence for CBOs, showing that their decision-making authority often varies while they are publicly recognized. The study also reveals that public documentation of funders' community engagement is often performative or symbolic rather than structurally embedded in decision-making processes. In addition, funding remains a barrier, with …

FRED is focused on informing policy on food waste prevention using a total food system sustainability approach.

Consumers sit at a critical point of food value networks as the decision-makers about food purchasing, household storage and management, and (non-)consumption. It was critical therefore to understand the consumer context, their concerns and needs regarding the food system, and their food purchasing and waste attitudes and behaviours.

Frozen Green Leaves As Potential Nutrient Subsidies In North American Mangrove Ecosystems, Katelyn Overstreet, Emily M. Dangremond, Ilka C. Feller

Biological Sciences Faculty Publications

Avicennia germinans, the black mangrove, has shifted its range limit northward, and increased in abundance in the Southeastern United States. In January 2018, a 3-day freeze event caused substantial defoliation of green leaves in A. germinans near its northernmost range limit in St. Augustine, FL. During their recovery, plants that lost their leaves grew similarly to plants fertilized with nitrogen, leading to the hypothesis that freeze-killed green leaves (frozen green) may have acted as a fertilizer. To assess the value of frozen green litter as a nutrient subsidy, we performed an experiment in which A. germinans seedlings were grown …

Graduate School of Oceanography Faculty Publications

The undersigned are scientists with expertise in per- and polyfluoroalkyl substances (PFASs) and/or the management of chemicals. We assert that the Organization for Economic Co-operation and Development (OECD) definition of PFASs is scientifically grounded, unambiguous, and well suited to identify these chemicals. We are concerned that some individuals and organizations are seeking a redefinition of PFASs endorsed by the International Union of Pure and Applied Chemistry (IUPAC) to exclude certain fluorinated chemical subgroups from the scope of the existing definition. We are concerned that this effort is politically and/or economically, rather than scientifically, motivated. An IUPAC-endorsed and potentially narrower PFAS …
