Fossil-Fuels In A Decarbonized Country? Modeling The Drivers Of Icelandic Oil Sales, Inbal Armony

Environmental Studies Honors Projects

Although 100% of Iceland’s electricity comes from renewable energy sources, it still relies on fossil fuels for land transportation, marine transportation, aviation, and some industry. Understanding geographic nuances in oil use is critical to achieving Iceland’s goals of carbon neutrality by 2040. As the island has one primary urban center with two thirds of the population, information is lacking about oil use in non-Capital areas and a gap between state and municipal climate plans. Using newly available data of oil sales at the municipality-level in a Small Area Estimation model, we analyze drivers of oil sales across Icelandic municipalities. We …

End Of Dino Dominance - Ecological Trends In Late Cretaceous Communities, Matthieu Weinberg, Liam Lucas, Katya Borkovskaya

Undergraduate Research and Engagement Symposium

We studied the ecosystem stability of an End-Cretaceous ecosystem out of the Lance Creek Formation in Wyoming. This ecosystem represented a time interval immediately before the mass extinction wiping out all non-avian dinosaurs. Overall, our data suggests that stability was relatively good leading up to the asteroid impact that catalyzed the mass extinction.

Linkage And The Loss Of Short Stamens In Arabidopsis Thaliana, Natalie Dresdner, Scarlett Dellacona, James Bingman, Jeffrey K. Conner

Research Symposium

How do genetic correlations between traits contribute to evolutionary processes? This study investigates the role of genetic linkage in an unexplained geographic cline of floral trait loss in Arabidopsis thaliana. A diagnostic characteristic of the Brassicaceae family is the arrangement of four long stamens and two short stamens in each flower. These short stamens are adaptive in outcrossing and have lost this function in highly selfing A. thaliana. Short stamens demonstrate incomplete loss across A. thaliana’s native range, with fewer stamens produced at lower altitudes and latitudes. We hypothesized that short stamen number is correlated with one or more traits …

Open Space Management Planning: A Framework And Case Study From Eagle Mountain City, Utah, Nathan K. Shumway

All Graduate Reports and Creative Projects, Fall 2023 to Present

Open Space Management Plans (OSMPs) are increasingly used by municipalities to guide the long-term stewardship of natural lands; however, little formal guidance exists regarding how these plans are structured, developed, or organized in practice. While numerous OSMPs are publicly available, their compositional logic, procedural workflows, and thematic priorities remain largely undocumented within academic literature. This study addresses that gap through a qualitative document analysis of fifteen publicly accessible OSMPs from the western United States, published between 2015 and 2024.

Using manual matrix-based coding in Microsoft Excel, each plan was analyzed through three lenses: structural composition, procedural development, and thematic content. …

Reading Cache Valley Rhetorics: Towards A Composition Pedagogy Of Place, Dax Gove

All Graduate Theses and Dissertations, Fall 2023 to Present

“Reading Cache Valley Rhetorics: Towards a Composition Pedagogy of Place” proposes that place—one’s immediate locale—is an essential element of ecocritical writing pedagogy. There are constant interacting rhetorical constructions of meaning within any given place across texts from the different groups who have lived there. In these local texts, the evidence of a rhetorically mediated reality is evident in the stark differences between natures and cultures—meaning is rhetorically constructed, down to the meaning of place and people. This project reads texts local to the author’s immediate locale, Cache Valley, Utah, from white LDS settler and Indigenous Shoshone rhetors in order to …

Desert Deep: The Great Salt Lake's Evanesce And The Gravity Of Recovery, Avery Truman

Undergraduate Honors Capstone Projects

The Great Salt Lake has been shrinking since the mid-19th century for several reasons, primarily due to a higher evaporation rate caused by climate change and water diversion from the Bear, Weber, and Jordan rivers. This problem will cause mass ecosystem destruction, release toxic chemicals into the air, and strand migrating birds. As an environmental studies and geography major, I’ve spent a lot of time learning about the Great Salt Lake in my courses. I decided to write Desert Deep, a series of essays, after I took my first creative nonfiction writing class. The goal was to tell the …

Chapter 1 discusses the environmental impacts of DRC cobalt mining and its adverse effects on public health. Environmentally degrading mining …

Consumerism In The Digital Age: Environmental And Cultural Consequences, Danielle Andrea Montoya

Student Theses 2015-Present

Overconsumption has emerged as a significant environmental problem, characterized by persistent patterns of buying, using, and discarding goods at rates that exceed ecological limits. In the digital age, these patterns of consumption are reinforced by economic systems, technological advancements, and cultural norms that make constant consumption feel normal and convenient. While consumption is necessary for everyday life, consumption beyond basic needs contributes to increased waste, resource depletion, pollution, and climate change. Overconsumption is embedded in daily habits such as online shopping, food consumption, and frequent product replacement. Therefore, understanding and addressing overconsumption is crucial for achieving environmental sustainability and social …

Intertidal Ecosystem Variation Along A Latitudinal Gradient Across The Gulf Of Maine, Reuven William Frye, Justin Baumann

Standard Theses

Rocky intertidal ecosystems are structured by environmental conditions and are particularly sensitive to climate change driven stressors such as ocean warming and acidification (Fernandez et al., 2020; Kleisner et al., 2017). This study examined algal and invertebrate community composition across eight rocky intertidal sites spanning northern and southern regions along the Gulf of Maine to assess how tidal height, site, and region shape species distributions and interactions. Surveys quantified percent cover and total count across low, mid, and high tidal zones, and patterns were analyzed using two-way ANOVA and Tukey HSD post hoc tests. Algal community composition varied significantly with …

Speaking Sustainability, Sustaining Extraction: Narratives Of Corporate Climate Obstruction Within The Unfccc, Liam Rule

Standard Theses

This thesis applies a critical lens to how the most influential corporate actors at the recent UNFCCC COPs seek to obstruct climate action and the green transition through a smoke screen of corporate environmental and sustainability discourses. Through a systematic deconstruction of these corporate documents, this study reveals a variety of key narratives through which corporations delay, deny, and foster inaction to climate action. The eight most influential corporations, determined by the InfluenceMap database as Amazon, BASF, Chevron, ExxonMobil, Shell, SINOPEC, Toyota, and Volkswagen, were selected based on their documented presence and strategic engagement at COPs 27-29. This research employs …

An Alternative To Armageddon: O.P. Weyland And The Development Of Tactical Air Power, Paul Wells

LSU New Orleans Theses and Dissertations

Theorists and advocates of air power argued that aircraft, not ground forces, would become the dominant platform for victory in war. They promoted the concept of strategic bombing, using aircraft to bypass ground forces and directly attack a nation's industrial capacity to wage war, hoping to ensure quick victory and avoid a repeat of the prolonged slaughter in the trenches of WWI. In 1947, led by advocates of strategic bombing, the United States Air Force (USAF) became an independent and equal branch of the U.S. military. The USAF developed the Strategic Air Command (SAC) to meet the requirements of the …

Programmable Degradation Of Polyethylene Via Amide-Functionalization: A Dual-Path Strategy Combining Palladium-Catalyzed Copolymerization And Enhanced Microbial Breakdown, Safi-Dapetel Balkissou Wouna

Master's Theses

Polyethylene (PE) is one of the most widely used polymers due to its durability, low cost, and chemical stability; however, these same properties contribute to its persistence in the environment. It takes about 1000 years for PE to be degraded by microbes in nature. This study investigates a molecular design strategy to enhance the biodegradability of PE by introducing polar functional groups into its backbone through palladium-catalyzed copolymerization with a Vince lactam-derived comonomer. This strategy was inspired by our previous observation that PHEVD (poly[7-(2-hydroxyethyl)-2,4-divinyl-3-oxa-7-azabicyclo[3.3.0]octane-6,8-dione]), a newly synthesized petroleum derived polymer that is rich of amide group, can be near-completely degraded …

Community Resilience In The Absence Of Aid: Recovery After The 2018 Father’S Day Flood In Houghton County, Michigan, Abby Heggem

University Honors Program Senior Projects

Community networks influenced resilience and recovery after the 2018 Father’s Day Flood in Houghton County Michigan, particularly in the absence of strong institutional support. The flood caused widespread damage to homes, roads, and infrastructure, forcing residents to rely on immediate local action before state or federal aid arrived. Rural locations like Houghton County are often neglected by government funding and support during disasters and are forced to rely on themselves. Community networks matter in disasters because neighbors, volunteer groups, and local leaders respond faster than formal institutions. This project uses a qualitative case study approach that includes content analysis of …
