Improving Human-Wildlife Coexistence: An Ecological And Educational Approach To Rewilding Grizzly Bears (Ursus Arctos Horribilis) In California, Amanda C. D. Rosales

Master's Projects and Capstones

Megafauna extinction during the Holocene has been both caused and amplified by climatic changes and human influence. By the last half century, large carnivores were diminished in Europe and the United States, but policies increasingly addressed species decline and their territories expanded. This research examined large carnivore rewilding across the European Union and United States, specifically for rewilding brown bears, Ursus arctos, in historic habitat. Next, case studies for the health status of climate-impacted whitebark pine, Pinus albicaulis, a high energy food for bears, was assessed. Ultimately, research case studies, human perspective surveys, and the California Department of Education content …

Taxidermy And Technology: A History Of Climate Change Exhibitions At American Museums Of Natural History, Laura Haushalter, Amy Woodson-Boulton

Honors Thesis

My research is on the history of temporary and permanent climate change exhibitions at natural history museums in the United States. My primary research question is: How have natural history museums responded to human-caused environmental destruction through their exhibitions, and what, if anything, are natural history museums doing now to address our current environmental crisis? My research begins with a historiography of natural museums and examines how early 20th-century museums responded to a sense of environmental crisis and widespread threats of species extinction. In the early 20th century, museums shifted from Victorian-era glass cases to modern and artistic dioramas that …

Evaluating Energy Transition Winners And Losers: Are Algae Biofuels Desirable, Feasible, And Viable?, Michelle M. Arnold

All Graduate Theses and Dissertations, Fall 2023 to Present

Climate change, environmental degradation, finite resources, and the uneven distribution of energy access all points to an urgent need for a global energy transition. But making that transition responsibly requires more than enthusiasm for “green” solutions—it demands careful evaluation of which energy sources are truly worth investing in. This dissertation develops a practical decision-making framework to help policymakers, scientists, and the public answer three foundational questions about any new energy technology: Is it desirable? Is it feasible? Is it viable? By systematically weighing public narratives, biophysical constraints, and patterns of innovation, the framework aims to prevent wasted time, funding, and …

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 …

Regulator Preferences And Underinvestment In Drinking Water Infrastructure, Chunyu Guo

Electronic Theses & Dissertations (2024 - present)

The infrastructure of U.S. drinking water systems faces chronic issues of low quality and underinvestment. As the water utilities in the U.S. are typically managed and regulated at the local municipal level, investment levels depend on the municipal regulator's preferences. Drawing from a dynamic framework, I specify and estimate the local regulators' objective function over drinking water infrastructure investment. This framework highlights the tradeoff between profit and consumer surplus and reveals how regulator preferences can deviate from net surplus optimization, resulting in underinvestment. My findings provide significant evidence that the drinking water infrastructure is underinvested. I reveal that the regulator's …

Increased weather hazards, decreased crop production, and drought are just a few of the hardships American farmers are facing in their fight to keep their farms alive and feed their communities, despite a rapidly changing climate. This study investigates how farmers can fight and prevent climate change through the use of specific mitigation and adaptation strategies on their farms. Semi- …

Climate Change Skepticism: Who And Why?, Mia Huyen Truong

Student Scholar Symposium Abstracts and Posters

Despite persistent scientific consensus urging immediate action, political polarization, and skepticism have hindered effective climate change mitigation, especially in the United States. This paper explores the factors influencing climate change attitudes among different groups, focusing on right-wing affiliates and Christian believers. Drawing on the Anti-Reflexivity Thesis (McCright and Dunlap, 2001-2010) and Information Processing Theory (Wood & Vedlitz, 2007), we investigate the effects of individual characteristics, including partisan ideology, party identification, educational attainment, and Christian faith. Using Wave 7 (2021) of the Chapman Survey of American Fears Survey, a nationwide sample of different fears among U.S. adults, this study aims to …

Grain-Washing: The Issue With Corn Ethanol As A Sustainable Aviation Fuel, Emily J. Rinn

Scripps Senior Theses

Decarbonizing the aviation sector remains one of the most prevalent obstacles in reducing the United States’ significant contribution to global greenhouse gas emissions. Launched in 2021, the Sustainable Aviation Fuel (SAF) Grand Challenge aims to supply enough fuel to meet 100% of demand by 2050 through reducing its production costs and enhancing its sustainable practices. Corn ethanol feedstock has been proposed to make up as much as half of all SAF production in the 2030 benchmark. This thesis explores the assemblage of corn ethanol – from its true environmental impacts, role in the future SAF market, to research claiming corn …

Policy Implications Of Managing Biodiversity And Natural Resources Across International Boundaries, Dillon Brown

Dissertations

Fisheries Management under the best of scenarios is a complex action. It requires thoughtful consideration of resources that tend to be out of sight, widely distributed, highly variable both spatially and temporally, and present dramatic variation in life history and ecology. No one management approach has been developed which can effectively incorporate all these variables. Add to this the issue of transnational boundary movements of these resources, and one discovers that this complex issue needs to be addressed by multiple entities, agencies, and nations to have any chance of success.

This research set out to discover ways in which fisheries …

The Impact Of Covid-19 On Wildlife Strike Rates In The United States, Dan Parsons, Michael Malouf, Wayne Martin

Human–Wildlife Interactions

Shortly after the COVID-19 pandemic impacted air traffic, industry bodies warned of the potential increase in wildlife strike risk. Prior to the pandemic, wildlife strikes were already a concern to the industry. We sought to evaluate industry warnings using interrupted time series analysis of wildlife strike trends in the United States. Using pre-pandemic wildlife strike trends, we compared a forecast of the expected monthly strike rates through the COVID-19 impact period (March 2020 to December 2020) to the actual wildlife strike rates for the same period. Our results showed an increase in wildlife strike rates in 5 out of the …

A Transdisciplinary Analysis Of Just Transition Pathways To 100% Renewable Electricity, Adewale Aremu Adesanya

Dissertations, Master's Theses and Master's Reports

The transition to using clean, affordable, and reliable electrical energy is critical for enhancing human opportunities and capabilities. In the United States, many states and localities are engaging in this transition despite the lack of ambitious federal policy support. This research builds on the theoretical framework of the multilevel perspective (MLP) of sociotechnical transitions as well as the concept of energy justice to investigate potential pathways to 100 percent renewable energy (RE) for electricity provision in the U.S. This research seeks to answer the question: what are the technical, policy, and perceptual pathways, barriers, and opportunities for just transition to …

Winter Bat Activity In A Landscape Without Traditional Hibernacula, Amy M. Hammesfahr, Rene E. Ohms

United States National Park Service: Publications

Abstract

Prior to 2014, bat research at Devils Tower National Monument (DETO) focused on bats present during the summer months. Biologists at DETO assumed local bats were strictly summer residents due to the presumed lack of typical habitat features associated with bat hibernation, such as caves and mines. This lack of traditional hibernacula features at DETO discouraged staff and research cooperators from studying winter bat populations. Despite the earlier assumption that bats were unlikely to hibernate on the monument, DETO documented significant winter bat activity through passive winter acoustic monitoring. This study is the first study at DETO that documents …
