Understanding The Impact Of Environmental Change On Shorebird Abundance And Distribution Across The Intermountain West Over The Past 30 Years, Sharon Montecino Aug 2026

Understanding The Impact Of Environmental Change On Shorebird Abundance And Distribution Across The Intermountain West Over The Past 30 Years, Sharon Montecino

All Graduate Theses and Dissertations, Fall 2023 to Present

Shorebirds have declined worldwide over the past century, mainly due to wetland loss and degradation. Wetlands are sites that are temporarily or permanently flooded and provide critical habitat for shorebirds, especially in arid and semi-arid regions such as the Intermountain West. However, climate change and human water use threaten these wetlands, and how these threats may affect shorebirds in this region remains poorly understood. In the early 1990s, shorebird counts at over 160 wetlands across the Intermountain West provided a broad assessment of shorebird populations in the region. These counts remained the only large-scale surveys until 2022, when the Intermountain …

Using Temporal Genomic Data To Uncover Patterns Of Genetic Diversity And Signatures Of Selection For Management Of A Threatened Minnow Species, Erika A. Dunn

Biology ETDs

The Little Colorado River (LCR) spinedace persists only in three isolated watersheds within the LCR Basin in Arizona. This imperiled minnow faces ongoing pressure from habitat alteration, climatic shifts, and invasive non-native predators. Over the past two decades, managers have translocated spinedace within watersheds to increase abundance and expand habitat occupancy. We sequenced a reference genome and analyzed single nucleotide polymorphisms (SNPs) from 475 individuals over their geographic range. DNA samples were obtained from a previous study in the mid-1990s and compared with samples from 2024 and 2025, allowing us to track genetic diversity, effective population size, population structure, and …

Determining Cave Presence And Diet Variation Of The Ozark Big-Eared Bat (Corynorhinus Townsendii Ingens) From Guano Dna, Lark E. Sybrant

ATU Theses and Dissertations 2021 - Present

The Ozark big-eared bat (Corynorhinus townsendii ingens; OBEB) is federally endangered in Arkansas, where it persists in a few small, geographically restricted populations within the Ozark National Forest. Although the region contains many caves that appear suitable for OBEB, expanded survey efforts are needed to locate additional roost sites for monitoring and protection. Effective conservation also requires a clear understanding of their distribution and diet. Traditional cave surveys can be disruptive and often miss cryptic species, and earlier diet studies based on manually sorting prey remains provided only coarse taxonomic resolution and overlooked soft‑bodied insects. To address these …

Invasive Macrofungi In The United States: A Mushrooming Crisis, Emily Torres May 2026

Invasive Macrofungi In The United States: A Mushrooming Crisis, Emily Torres

Student Theses 2015-Present

Globalization has accelerated the spread of invasive species, making them one of the largest contributors to biodiversity loss worldwide. While invasive macrofungi remain largely absent from scientific discourse on invasive species, they represent a growing ecological concern throughout the United States. Invasive macrofungi disrupt forest ecosystems, alter soil communities, and displace native fungi. Beyond these ecological impacts, their presence and establishment profoundly affect human-nature relationships, most notably mushroom foraging and cultivation practices. This paper adopts a multidisciplinary approach to examine the ecological, economic, and anthropogenic impacts of invasive macrofungi in the United States. Chapter 1 provides a quantitative overview of …

Investigating The Taxonomic Uncertainties Of Potentilla Rupincola, Natalie Elizabeth Hieber May 2026

Investigating The Taxonomic Uncertainties Of Potentilla Rupincola, Natalie Elizabeth Hieber

Master's Theses

Landscape stewardship is an integral role for land managers that becomes more important when rare or endangered species occur within managed areas. Conservation across the landscape is a primary concern for land managers, but resources allocated for conservation can be limited due to many competing goals. Taxonomic uncertainty surrounding rare and endangered taxa, particularly plant taxa, that have historically been classified solely using morphological features further complicates conservation planning. One such taxon is Potentilla rupincola, a rare plant endemic to the eastern Rocky Mountains in Colorado. For over a century, botanists have debated whether P. rupincola is a distinct species …

Trawling For Clues: Examining Nefmc Herring Amendment 8, Christopher Santoro May 2026

Trawling For Clues: Examining Nefmc Herring Amendment 8, Christopher Santoro

Honors Scholar Theses

In 2007, almost twenty years ago, the Magnuson-Stevens Act changed the landscape of fisheries management in the US. Through the establishment of Fisheries Management Councils (FMCs), it paved the way for top-down management approaches that helped the government combat nationwide declines or collapses in fish stocks. Among the myriad responsibilities of the FMCs was the expectation that amendments to existing fisheries management plans would be a necessity to adapt to modern circumstances. This thesis focuses on New England Fisheries Management Council's (NEFMC's) Herring Amendment 8 (A8). This amendment, passed in 2021, attempts to lay the groundwork for sustainable management of …

Biology

Amphibious animals, such as frogs, are found at the intersection of aquatic and terrestrial ecosystems. They may serve as keystone and sentinel species and play key roles in nutrient cycling and food webs. In recent decades, amphibians have experienced drastic population declines due to habitat loss, climate change, and disease. These declines have prompted investments in ex situ conservation and captive breeding programs, which aim to reduce extinction risk by creating assurance colonies and reintroducing individuals once threats are mitigated. A critical component of these programs is proper husbandry, which ensures the health and longevity of captive populations and their …

Environmental Inequities In Conservation Policies And Practices: A Brief Overview, Monyai Chavers Mar 2026

Environmental Inequities In Conservation Policies And Practices: A Brief Overview, Monyai Chavers

Professional Agricultural Workers Journal

Conservation science and practice mirror racist notions of colonialism, prolonging a cycle in which policies and programs disregard land access. Many conservation leaders operate from a culture of land exclusion, focusing on nature to generate wealth, deeming the number of individuals removed from the commons as progress. By the turn of the 21st Century, government conservation policies compensated private actors and groups for voluntarily adopting market-based mechanisms aimed at land conservation. Despite the emergence of various conservation programs, the data show that White Americans primarily benefit from federal conservation payments. However, the fragmentation of Black land ownership allows the …
