Microbiome Assembly And Function In The Solitary Mason Bee, Osmia Lignaria (Megachilidae), Bailey Crowley

All Graduate Theses and Dissertations, Fall 2023 to Present

Animal-microbe interactions can influence host biology, ecology, and evolution. The assembly and function of microbes found within animal hosts oftentimes depends on which species are involved. Advances in sequencing technologies have permitted the exploration of host-microbe interactions in a variety of animals, including bees. Early research aimed at understanding the microbiomes of social bees, such as honey bees and bumble bees, found that microbes prevent the spoilage of stored pollen, breakdown indigestible nutrients into smaller molecules available for uptake by the host, and also protect the host from pathogens. When environmental stressors, such as increased temperatures, disrupt the microbiome, the …

Beach Autonomous Zone, Carl Garvey

Masters Theses

This thesis project responds to issues surrounding beach erosion on Long Island’s Atlantic Coast by envisioning policy and design decisions that activate a destabilization of the shoreline and a managed retreat away from beaches. Contrasted to methods and goals of conventional coastal engineering, a beach autonomous zone sets an extended, moving setback in which coastlines are treated, in effect, as conservation easements, allowing for and encouraging beaches to return to more natural states. On four sites of different scales representing different built beachfront conditions, I visualize the negotiations between human desires and the needs of a beach that arise under …

Impact Of Climate Change On Carbon And Nitrogen Balance In Zostera Marina L. (Eelgrass), Malee Jinuntuya

OES Theses and Dissertations

Seagrasses face vulnerability to both global stressors like Ocean Acidification (OA) and climate warming compounded by local stressors such as eutrophication that reduces light availability, leading to a complex dynamic of positive and negative effect on their growth and survival. Increased dissolved aqueous CO₂ (CO_2(aq)) benefits seagrasses by enhancing photosynthetic and growth rates, but it may increase nutrient demand, potentially depleting nutrient supply, especially in oligotrophic environments.

In this study, the long-term impact of CO₂ on Zostera marina L. (eelgrass) were investigated across a gradient of CO_2(aq) concentrations (55 – 2200 µM CO_{2(aq)) …}

Interactive Effects Of Co2, Temperature, And Nitrate Limitation On The Growth And Physiology Of Marine Cyanobacterium Synechococcus Sp. Ccmp 1334, Alyssa K. Sharbaugh

LSU Master's Theses

The marine cyanobacterium Synechococcus sp. CCMP 1334 was grown in a continuous culture system on a 12:12 h light:dark cycle at all combinations of low and high pCO2 (400 and 1000 ppmv, respectively), nitrate availability (nitrate-limited and nutrient-replete conditions), and temperatures of 21°C, 24°C, 28°C, 32°C, and 35°C. The maximum median nutrient-replete growth rate was ~1.15 d−1 at 32 –35°C. Median growth rates at 1000 ppmv pCO2 were higher than those at 400 ppmv at all temperatures, but most of the differences were statistically insignificant. Carbon:nitrogen ratios were independent of pCO2 at a fixed relative growth rate but decreased with …

Extinction Anxiety As Zeitgeist: An Examination Of The Cultural Anxiety Surrounding Extinction Threats, Spencer J. Kett

Electronic Thesis and Dissertation Repository

This thesis examines extinction anxiety as a zeitgeist that manifests through nuclear war anxiety and climate change anxiety. I define extinction anxiety as the cultural mood of anxiousness surrounding extinction threats in the past, present, and future. I use Monika Krause’s sociological conception of zeitgeist to understand these anxieties as a cultural mood. I demonstrate using Jean-Paul Sartre’s conceptualization of materially derived subjectivity, how these moods of anxiousness are internalized through material conditions. I build my concept of extinction anxiety by comparing and contrasting the mood of anxiousness surrounding nuclear war during the Cold War and the current mood of …

The Role Of Local Knowledge In Climate Change Research, Ryan E. Mccoy

Theses and Dissertations--Philosophy

This dissertation addresses the growing need within climate research for improvements in regional and local climate information. I argue that knowledge gaps in regional climate information constitute a form of climate injustice in which harm largely falls on regions most vulnerable to climate change. Moreover, I show that our current methods for garnering regional climate information fail to provide information on place-specific factors, such as local culture, socio-economic systems, and ecology, which mediate climate change impacts. In order to address these knowledge gaps, as well as provide information necessary for effective mitigation and adaptation, I argue for the inclusion of …

Environmental Implications Of Modern Food Production: An Analysis For The Conscious Consumer, Jessica T. Coming

Cal Poly Humboldt theses and projects

This project explores the pathways by which agriculture affects the environment and determines which foods have the greatest climate, water, and land impacts. Agricultural effects on the environment are extensive, from loss of habitat and declines in regional biodiversity to disruption of global nutrient cycles and climate change. Global food production accounts for 26-34% of annual anthropogenic greenhouse gas emissions, makes up 38-46% of habitable land, and is responsible for 70% of freshwater extraction. The effect of agriculture on the environment is most significantly dictated by what type of food is being produced. Animal-based food products consistently have the highest …

Climate Change And Coastal Development Impacts On Oyster Abundances In Mosquito Lagoon, Fl, Emily Suchonic

Graduate Thesis and Dissertation 2023-2024

Live eastern oyster (Crassostrea virginica) reefs have declined by 62.6% in Mosquito Lagoon (ML) along the eastern Florida coast since 1943. While this species creates reefs by successive generations of oysters recruiting to conspecific shells, C. virginica can also attach to non-reef substrates including mangrove roots and armoring (e.g., seawalls), which may help counteract reef habitat loss. In recent decades, warmer winters have enabled red (Rhizophora mangle) and black (Avicennia germinans) mangrove expansion in subtropical salt marshes and temperate estuaries where oyster reefs occur. Additionally, 11.8% of ML's shorelines have been armored as of …

Changing The Communication For A Changing Climate: Effects Of Climate Change Communication On Identity, Emotions, And Mobilization, Liam Schwartz

Departmental Honors Projects

What are the most constructive emotions to evoke in climate change communication for diverse groups of people in a way that encourages pro-environmental behavior? A specific communication style and subsequent emotional response may best mobilize people interested in efforts to address climate change compared to people who are less invested in the issue. In this study, 927 valid participants surveyed were randomly assigned to one of three groups: a “fear” condition, a “hope” condition, and a control condition. All participants were asked a series of questions about their demographics, identities, perceptions, values, and environmental attitudes. Following these experimental tasks, they …

Assessment Of Open Top Chambers To Simulate Effects Of Climate Change On Soil Temperature And Cover Crop Response In Agricultural Systems, Gretchen Bahmueller

Honors Theses and Capstones

Climate change is expected to yield warmer winters that have the potential to place additional stress on our already stressed agricultural systems. Understanding how agricultural systems may respond to these changes is essential to creating crop and land management plans that ensure food security for future generations. To better understand how warming winters can/will affect air and soil temperatures and cover crop performance, open top chambers (OTCs) were deployed post cover crop seeding in a field experiment at the UNH Kingman Research Farm in Madbury, NH. The experiment consisted of four cover crop treatments sown into or after corn: an …

Interannual Growth-Climate Relationships Of Western Larch After Wildfire In The Northwest, Junior Burks

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Montane and mixed-conifer forests in the northwestern United States are burning at rates greater than any time in recent decades, due to the combined impacts of global warming and historical and contemporary land use and land management. Western larch (Larix occidentalis) is a tree of high regional significance, exhibiting a variety of traits that make it resistant and resilient to fire. Because seedlings are more sensitive to environmental stressors than adults, the impacts of climate change are expected to be detectable first in juvenile trees. Recent research shows that the natural regeneration of western larch after wildfires has …

The Effect Of Solvent Identity And Hydride-Donor On The Reduction Of Co2 Into Useful Fuels, Abigail Mcentire

Honors Theses

One possible strategy for decreasing CO2 emissions is through electrocatalytic reduction reactions to convert the CO2 back into combustible fuels , such as methane or methanol. However, it can be challenging to control the reaction to select one of these useful fuels as opposed to carbon monoxide or formate. Our strategy is to investigate a specific hydride donor and solvent combinations for which the reaction favors conversion to methanol. It was found that in acetonitrile , several hydride donors were capable of selective reduction of CO2 to the methanol oxidation state.

Landscape Design That Enhances Socialization And Community Through Climate Resilience, Guidelines For North Texas Universities., Melissa N. Brown

Landscape Architecture Masters & Design Theses

Landscape architects must balance social, economic, and environmental considerations while creating places that people will love. And, in the words of American Society for Landscape Architects Fellow Mary Margaret Jones: “If we don’t make places people love, they won’t be taken care of”. (ALSA Interview, n.d.) Consideration for the user experience will result in spaces that people are more likely to love.

The growing student population at the University of Texas at Arlington means that every space must be used to its full potential. The green and open spaces on a university campus are more than circulatory routes between buildings. …
