Isolation, Identification, And Enzymatic Screening Of Fungi From Utah Dryland Soils For Industrial And Waste Valorization Applications, Jessica Lorena Silva Cuero

All Graduate Reports and Creative Projects, Fall 2023 to Present

Agricultural waste accumulation presents environmental challenges but also opportunities for biological valorization into value-added products. Fungi are particularly well-suited for this purpose due to their capacity to produce extracellular enzymes involved in the degradation of complex organic substrates. Dryland ecosystems represent a promising source for bioprospecting microbes capable of producing such enzymes. Drylands harbor a high diversity of extremophilic microorganisms that can withstand harsh conditions, extreme heat, UV, and low nutrients using unique adaptations. This suggests that these microbes are resilient and capable of surviving under varying conditions and still produce enzymes for biotransformation. The objective of this study was …

Integrated Soil-Water Processes And Irrigation Management For Agricultural Water Optimization In Semi-Arid Regions, Tejinder Singh

All Graduate Theses and Dissertations, Fall 2023 to Present

Water is one of the most important resources for agriculture in the western United States. In semi-arid regions, farmers depend on irrigation to grow crops, but water supplies are becoming less reliable because of drought, declining snowpack, groundwater depletion, and increasing competition for limited water. Improving agricultural water use is therefore not simply about applying less water. It also requires understanding where water goes after it enters a field, how long it remains available to crops, and how farmers can use that information to make better irrigation decisions. This dissertation follows water through irrigated agricultural systems to better understand how …

Resilience, Hope, And Posttraumatic Growth Among Yazidi Refugees, Erin Elizabeth Larson

All Graduate Theses and Dissertations, Fall 2023 to Present

Although it has been more than a decade since the Islamic State of Iraq and Syria (ISIS) imposed genocide upon the Yazidi people, an ethnic minority indigenous to Kurdistan, research on the psychological health of this community is lacking. While traumatic experiences and the accumulation of stressors can overwhelm one’s capacity for resilience, making it especially difficult for refugees to adapt and recover from their experiences. Posttraumatic Growth Theory posits that individuals may overcome such challenges and even undergo positive life transformations. Data were collected from Yazidi young adults using an online survey and examined the associations between resilience, hope, …

Developing A New Uas Method For Estimating Heat Exposure On Western Us Trails, Jared Young

All Graduate Theses and Dissertations, Fall 2023 to Present

Heat exposure and the risks to human health that stem from it have been studied extensively in the context of urban and occupational settings. Less studied however, is the effect of heat exposure in a recreational setting such as on hiking trails. What makes this fact more surprising is that recreation, especially in the Western US, is extremely popular, with national parks such as Zion and Arches bringing in hundreds of thousands of visitors every year. With millions of recreationists exposed to the hazard of heat every year, it is critical that recreationists are made aware of the dangers they …

Drought And Diet Breadth: Does Insect Specialization Influence Herbivory When Plants Are Under Stress?, Jakob Palmer

All Graduate Theses and Dissertations, Fall 2023 to Present

Climate change will alter precipitation worldwide, causing more frequent and severe drought events worldwide. Drought affects many ecological processes, including plant-herbivore interactions, which are critical to biodiversity and ecosystem health. A variety of plant characteristics can influence herbivory – such as how hairy, nutritious, or toxic a leaf is – and drought has been shown to alter many of these traits. Unique characteristics of herbivore species are also important: herbivores can either feed on a variety of plants (generalists) or a group of closely related plants (specialists). Specialists can cope with traits of the plants they eat, while generalists are …

Using the United States as a case study, this study examines the relationship between presidential executive orders and democratic quality from 2017 to 2025. More specifically, it investigates whether characteristics of executive orders correspond with changes in democratic quality, measured using the Liberal Democracy Index and the Judicial Constraints Index from the Varieties of Democracy (V-Dem) Project.

Presidential executive order issued between 2017 and 2025 were collected from the …

A Cfd-Dem Framework For Characterizing Nanoparticle Adhesion Effects On Creeping-Flow Permeability In Composite Manufacturing, Gavin Stoker

All Graduate Theses and Dissertations, Fall 2023 to Present

Modern aircraft, spacecraft, and high-performance vehicles are increasingly built from composite materials, engineered combinations of plastics and fibers that are lighter and stronger than traditional metals. Researchers are now pushing these materials further by mixing in microscopic particles thousands of times smaller than a human hair, called nanoparticles, to make them even tougher and more resistant to damage. The challenge is getting those nanoparticles distributed evenly. During manufacturing, liquid plastic resin is pumped through a network of tightly packed fibers, carrying the nanoparticles along with it. But nanoparticles tend to clump together and stick to surfaces as they travel, clogging …

Microbes In Pollination Systems: Effects On Pollinator Health, Floral Traits, Nectar Robbing, And Plant Fitness, Valerie Nicole Martin

All Graduate Theses and Dissertations, Fall 2023 to Present

Flowers produce nectar to attract pollinators, but nectar is also a habitat for yeasts and bacteria that arrive via pollinators, robbers, and other visitors. These microbes consume nectar sugars and release byproducts that change the smell and taste of nectar. Whether these changes affect how pollinators find and choose flowers, and whether they ultimately affect how many seeds a plant produces, is not well understood. In this dissertation, I studied how a common nectar yeast and a plant-associated bacterium affect the scent of wildflowers, the behavior of bumble bees and hummingbirds, and plant reproduction in montane meadows in central Colorado. …
