How Mineral Fertilizer Affects Soil Nitrogen Pools And Microbial Activity, Lee Hildebrand Sep 2024

How Mineral Fertilizer Affects Soil Nitrogen Pools And Microbial Activity, Lee Hildebrand

Master's Theses and Capstones

Nitrogen fertilizer is an essential aspect of modern agriculture; however, a substantial amount of applied nitrogen does not reach the crops it is intended for and leaches out of the soil. Soil organic matter and microbial activity are key regulators of the soil nitrogen cycle and the fate of nitrogen fertilizer. Understanding how fertilizer type impacts soil organic matter, nitrogen pools, and microbial activity will greatly improve our understanding regarding sustainable fertilizer application. To investigate this, I conducted an experiment using incubation with several fertilizer treatments and two soil types. I measured various soil nitrogen pools, soil respiration rates, and …

Investigating Temperature And Emissivity Separation Techniques Through The Use Of A Spectral Emissivity Database, Mitchell A. Manzardo Sep 2024

Investigating Temperature And Emissivity Separation Techniques Through The Use Of A Spectral Emissivity Database, Mitchell A. Manzardo

Theses and Dissertations

This study evaluates two temperature and emissivity separation techniques using data from an ABB MR304 FTIR and a Telops Mid-Wave Hyper-Cam on carbon-based samples heated by a high-energy laser. The established Linear Spectral Emissivity Constraint (LSEC) and Gray Body Emissivity (GBE) methods, as well as a new Robust Ratio Linear Fitting (RRF) method are assessed for their applicability in controlled lab environments. A spectral emissivity database aids in analyzing method performance. The RRF method shows promise but has limitations, particularly with low-temperature data and complex Hyper-Cam data. Despite these challenges, the RRF method offers potential for further refinement.

School of Geography, Earth and Environmental Sciences

Peatlands are potent landscape sinks of natural and industrial toxic metals and metalloids (TMMs) but the long-term sequestration of TMMs in peatlands is at increasing risk due to climate change enhanced peatland fires. The ability of peatlands to retain TMMs results from a host of interacting hydrological, biological, geomorphological, and chemical feedbacks, which underpin peatland functionality in general. Fire is a transformative force that often disrupts these interactions and feedbacks, leading to the potential release of TMMs to our air, land, and water. Given that wildfire burned area and severity are increasing there is a need for a conceptual understanding …


The Cubic Bipolar Neutrosophic Sets Theory And Uncertainty Management In Environmental Data Analysis, A. A. Salama, Huda E. Khalid, Ahmed G. Mabrouk Sep 2024

The Cubic Bipolar Neutrosophic Sets Theory And Uncertainty Management In Environmental Data Analysis, A. A. Salama, Huda E. Khalid, Ahmed G. Mabrouk

Neutrosophic Sets and Systems

Environmental data analysis often faces uncertainties in measurements. Cubic Bipolar Neutrosophic Sets (CBN Sets) provide a powerful framework to address this challenge. This paper explores the mathematical foundations of CBN Sets and highlights their practical applications through illustrative examples. We demonstrate how CBN Sets effectively capture varying degrees of certainty, possibility, and impermanence in environmental parameters. The concept of inclusion relations facilitates comparisons and information fusion. Fundamental set operations (intersection, union, complement) are explored for manipulating and analyzing uncertain environmental data. We present the application of CBN Sets in water quality assessment, highlighting their ability to analyze parameters while accounting …

Dissertations, Theses, and Capstone Projects

This dissertation provides an historical analysis of repurposed material adventure playgrounds in the United States between 1949 and 1999. Three microhistories of adventure playgrounds (The Yard, in Minneapolis, M.N., and several playgrounds in New York City, N.Y., and Houston, T.X.) are framed against the wider socio-economic changes that shaped more than thirty-five adventure playgrounds in the United States over the period of study. By focusing on the relationships mobilized by adventure playground advocates at different scales and across different points of view, and how these networks shaped the local production of spaces for play, this dissertation's method underlines the importance …


Unpacking Normative Change: The United Nations At Its 60th Anniversary, Giovanna Marques Kuele Sep 2024

Unpacking Normative Change: The United Nations At Its 60th Anniversary, Giovanna Marques Kuele

Dissertations, Theses, and Capstone Projects

This dissertation explores the UN at its 60th anniversary at a critical juncture, with seven nested observations, to answer why normative change happens at the UN, when it is triggered, and which proposed changes are ultimately adopted. It argues that normative change at the UN is a result of multilevel political consensus at critical junctures. At the macro level, these junctures are triggered by global crises and international summits that provide a moment of normative reflection among the three UNs—member states, secretariat, and non-state actors—thereby increasing the likelihood of achieving multilevel political consensus. At the micro level, the formation of …

Relationship Of Flood Peaks To 24-Hour Rainfall In The Eastern Texas Hill Country, South-Central Texas, Richard A. Earl, Jeanett Bosarge, Heather Wooten, Sarita Hedgepeth, Joel Sherrouse

The Geographical Bulletin

The eastern Texas Hill Country is noted for its extreme storm rainfall amounts and the resulting flood discharges. The resulting flash f loods contribute to Texas leading the U.S. in automobile-related, flood fatalities. These f loods produce considerable groundwater recharge to the Edwards Aquifer. A better knowledge of relations between precipitation and peak flood discharges can improve f lood hazard warning and provide estimates of groundwater recharge from ungauged ephemeral streams. The purpose of this study was to analyze the relationship between 24-hour precipitation amounts and peak discharge for four ephemeral streams, with drainage areas between 0.3 to 18.8 mi.2 …


Far-Right Ecological Extremism: The Synthesis Of Violence, Hate, And The Environment On /Pol/., Hannah Claire Dunleavy Aug 2024

Far-Right Ecological Extremism: The Synthesis Of Violence, Hate, And The Environment On /Pol/., Hannah Claire Dunleavy

Environmental Studies Senior Theses

American far-right ecologism incorporates the American far-right’s antidemocratic and exclusionary tendencies, fears of existential threats and conspiracies, apocalyptic fantasies, and commitment to racial hierarchies. There are many shades of far-right ecologisms – including authoritarian deep ecology, eco-fascism, and exclusionary eco-nationalism – but all threaten the United States’ democratic ideals, multiculturalism, and pluralistic society. This thesis examines the rise of far-right ecologism in the U.S. by analyzing posts from 4chan’s /pol/ board (2015–2020) with a mixed-methods that blends a literature review, quantitative analysis, and descriptive case study. From 2015 to 2019, far-right ecology posts increased by 410%, and violent rhetoric in …

Climate Science, The Military-Industrial Complex, And The Political Economy Of Knowledge-Making: Beyond The Capitalist Ontology Of Nature?, Daniel Cunha Aug 2024

Climate Science, The Military-Industrial Complex, And The Political Economy Of Knowledge-Making: Beyond The Capitalist Ontology Of Nature?, Daniel Cunha

Emancipations: A Journal of Critical Social Analysis

Climate science is one of the main political drivers of today’s world, informing critical scholars and social movements alike. Yet, many scholars associate it with projects of domination (the Cold War, capitalism, imperialism) while relying on it to elaborate a critique of capital. This article proposes a new historical account of climate science. Drawing from archival findings, interpreted with historical sociology combined with the critique of political economy, the article shows that a conflict developed at the National Academy of Sciences during the Vietnam War, between scientists who wanted atmospheric research to be under the auspices of NATO, as proposed …

Paige Fischer, Harrison Fried, Matthew Hamilton, Federico Holm, Jordan Inskeep, Max Nielsen-Pincus, Multiple Additional Authors

Environmental Science and Management Faculty Publications and Presentations

Environmental governance outcomes hinge on the design and implementation of management decisions. Yet, available research methodologies can be limited in their ability to capture the complexity of decision-making and implementation processes and in turn predict and explain environmental governance outcomes. We present participatory process mapping as a method for examining the pathways that emerge and evolve over time that result in natural resource management decisions and on-the-ground outcomes, as perceived by participants in collaborative processes. The approach leverages a large-N comparative design, participatory diagraming within semi-structured interviews, and mental modeling toward a method that can fit into both quantitative and …


Key Largo Mangrove Population Monitoring: A Remote Sensing Analysis And Classification Methodology Review, David Lackajs Aug 2024

Key Largo Mangrove Population Monitoring: A Remote Sensing Analysis And Classification Methodology Review, David Lackajs

Geography and the Environment: Graduate Student Capstones

Mangrove forests are some of the world's most bio-diverse habitats, providing essential services to the surrounding coasts. Removal of these habitats has a devastating impact on the ecosystems within them. The Florida Keys are some of the last areas in the United States with extensive mangrove populations. One specific area, John Pennekamp Coral Reef State Park in Key Largo, has been under state protection since 1959. For that reason, mangrove forest habitats there are less fragmented. This study uses remotely sensed imagery to quantify and analyze mangrove populations in this area using two methods: sub-pixel analysis and supervised classification. The …

Insurance Coverage And Flood Exposure In The Gulf Of Mexico Region: Risk, Social Vulnerability, Urban Form, And Scale, Anissa J. Hyde Aug 2024

Insurance Coverage And Flood Exposure In The Gulf Of Mexico Region: Risk, Social Vulnerability, Urban Form, And Scale, Anissa J. Hyde

LSU Master's Theses

Increasing flood losses in the Gulf of Mexico pose serious threats to resilience and insurability. The purpose of this study is to understand how scale, social vulnerability, risk and urban form relate to NFIP insurance coverage and flood exposure. Our multilevel models identify that flooding is significantly clustered by region and counties, especially shoreline counties. Our measures of risk suggest that the FEMA Special Flood Hazard Areas underestimates risk and exposure when compared with Flood Factor, and that there is some compensation in terms of insurance coverage, suggesting a pattern of adverse selection. Older housing stock appears both less insured …
