Invasive Earthworms In The Crown Of The Continent System And Implications For Land Management, Meghan Elizabeth Scott

Graduate Student Theses, Dissertations, & Professional Papers

The United States contains invasive earthworms originating from Europe and Asia; the majority are European lumbricids. Direct introduction occurs primarily through human activity and, once established, earthworm populations are difficult to address. When exotic earthworms engage in bioturbation, they negatively alter subterranean food webs and nutrient cycling by disrupting soil layering systems. The most prominent form of physical alteration is the change and removal of the topmost organic layer. This disruption is associated with altered nitrogen and carbon cycling, as well as altered forest floor plant communities.

The Crown of the Continent ecosystem is located in southwestern Alberta, southeastern British …

Hunger On The Richest Hill: A Case Study Of Linked Historical And Contemporary Food Insecurity In Butte, Montana, Elizabeth Anne Bett Osborn

Graduate Student Theses, Dissertations, & Professional Papers

On the “Richest Hill on Earth” or Butte, Montana, a dilemma of food insecurity persists. This dilemma broadly consists of limited access to affordable, healthy, and appropriate nutrition for the city’s urban population. This thesis constructs a historically and contextually-informed understanding of food insecurity in Butte since the city’s establishment in 1864. Food insecurity research largely lacks place-specific consideration of historical events and processes which contribute to and reinforce the root factors contributing to food insecurity. Butte was once a thriving copper-mining boom town yet saw the decline of its primary industry in the late 20^th century. In 2020, …

Moccasin Economics: Entangled Museum Stories Of Niitsitapi Women, Labor, And Footwear, Michaela Ann Shifley

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation emphasizes how anthropologists can use museum collections as anthropological data banks (Sturtevant 1973) to uncover the unwritten histories of objects, people, and cultures. I show how museum collections are repositories for the untold stories of Native women’s economic histories and how objects embody women’s critical contributions to the economic, spiritual, and cultural survival of their communities throughout time. To reveal the complex, hidden labor processes involved in historical and contemporary moccasin-making, I draw on interviews with contemporary Niitsitapi moccasin-makers, as well as object-based analyses of 109 pairs of moccasins from five museum collections and numerous archival documents and …

The researcher was not granted access to review further data that could provide more concrete answers to the …

A Non-Deterministic Deep Learning Based Surrogate For Ice Sheet Modeling, Hannah Jordan

Graduate Student Theses, Dissertations, & Professional Papers

Surrogate modeling is a new and expanding field in the world of deep learning, providing a computationally inexpensive way to approximate results from computationally demanding high-fidelity simulations. Ice sheet modeling is one of these computationally expensive models, the model used in this study currently requires between 10 and 20 minutes to complete one simulation. While this process is adequate for certain applications, the ability to use sampling approaches to perform statistical inference becomes infeasible. This issue can be overcome by using a surrogate model to approximate the ice sheet model, bringing the time to produce output down to a tenth …

The Role Of Acculturation On The Relationship Between Selfcompassion And Depression Within Native Americans, Kristen Kaylie Pyke-Pierce

Graduate Student Theses, Dissertations, & Professional Papers

Research examining the relationship between depression and self-compassion in a Native American (NA) sample is limited (Tielke, 2016). Previous research has found a negative relationship between depression and self-compassion in the general population (Johnson & O’Brien, 2013; Macbeth & Gumley, 2012; Neff, 2003b). Additionally, culture has been found to be beneficial in decreasing depression symptoms in NA persons (Whitbeck et al., 2002). Furthermore, as far as this researcher knows, there is no research examining the relationship between depression, self-compassion and acculturation in a NA sample. This study explored the relationship between depression and self-compassion while utilizing acculturation as a moderator …

Combinatorial Administration Of Synthetic Tlr4 Agonist Ini-2002 And Novel Mincle Agonist Um-1098 Delivered Via A-Snps Results In Synergistic Il-1Β Production In Human Primary Cells And Enhances Th1 And Th17 Responses In Vivo, Grace D. Jones, Asia Marie Stephanie Riel, Alexander Riffey, Cassandra Buhl

Graduate Student Theses, Dissertations, & Professional Papers

Tuberculosis (TB) kills more people each year than any infectious disease worldwide with recent exception of SARS-CoV-2. Though the Bacille Calmette Guerin (BCG) vaccine confers protection against severe extrapulmonary forms of TB, there is no licensed vaccine for the prevention of pulmonary tuberculosis. The strongest correlate of protection against pulmonary tuberculosis is Th1/Th17 biased cell mediated immunity. Several candidates for TB vaccine adjuvants have shown Th1/Th17 polarizing capacity in clinical trials including Mincle agonist trehalose dibehenate (TDB) and TLR4 agonist monophosphoryl lipid A (MPL). Furthermore, combinatorial administration of MPL and TDB formulated in dimethyldioctadecylammonium (DDA) liposomes has been previously reported …

Lidar-Landsat Covariance For Predicting Canopy Fuels, Margaret D. Epstein

Graduate Student Theses, Dissertations, & Professional Papers

Managing wildfires in the western United States is becoming increasingly complex. Visualizing and quantifying canopy structures allows fire managers to both plan for fire and track recovery. Light detecting and ranging, or LiDAR can measure forests in three dimensions, but has limited spatial and temporal coverage. LiDAR-Landsat covariance uses machine learning to fill in the spatial and temporal gaps of LiDAR coverage with supplemental Landsat imagery. However, in order to capture real forest dynamics, a model needs to be stable enough to detect long term trends, sensitive to episodic disturbance, and general enough to work on multiple landcovers. The purpose …

Hydrogeomorphic Response Of Steep Streams Following Severe Wildfire In The Western Cascades, Oregon, David Matthew Busby

Graduate Student Theses, Dissertations, & Professional Papers

Severe wildfire may alter the morphologic resilience of steep mountain streams by increasing peak discharges, elevating inputs of sediment and wood into channels, and increasing susceptibility to landslides and debris flows. In the Pacific Northwest, where mean annual precipitation is high and mean fire return intervals range from decades to centuries, understanding of steep stream response to fire is limited. In 2020, the Western Cascade Range, Oregon, experienced wildfire of historic magnitude and severity. The objective of this study was to evaluate the hydrologic and geomorphic response of steep streams to the 2020 fires. I assessed streamflow, instream wood, and …

Rethinking Rare: Novel Approaches To Rare Species Monitoring And Conservation, Jessie Deanne Golding

Graduate Student Theses, Dissertations, & Professional Papers

Conservation of rare species is widely valued and important for ecosystems. Unfortunately, many of the approaches to conserve rare species have been developed with common species (e.g., harvested species) which have larger populations and targeted objectives. Conservation of rare species is difficult in part because of problems created by scarcity and low information. With low information, learning leads to new questions and the utility of information in decisions can quickly become obsolete. Therefore, monitoring strategies that can adapt as well as provide information tailored to relevant decisions are needed. To address rare species monitoring, I developed a long-term monitoring approach …

Traumatic Brain Injury: An Interdisciplinary Approach To Healthcare Oversight, Charles Robert Brown Gatlin

Graduate Student Theses, Dissertations, & Professional Papers

Introduction: State licensing boards (SLBs) serve as overseers to protect the interests of the public by ensuring that individuals who operate under a license to practice in a state uphold the standards of their profession. However, resolving complaints regarding unprofessional conduct for conditions that necessitate interdisciplinary care, such as traumatic brain injury (TBI), may necessitate involvement from SLBs of other disciplines who are most qualified to evaluate the appropriateness of care. To date, there is no single pathway to address complaints regarding the interdisciplinary management of TBI as the mechanisms of the injury are complex, often do not address the …

The Evolution Of Morphological Diversity And Sexual Dimorphism In Stick And Leaf Insects, Romain Pascal Gilbert Eric Boisseau

Graduate Student Theses, Dissertations, & Professional Papers

How has the diversity of life forms come to be? This question is at the core of evolutionary biology and can be addressed at different scales: by studying the processes that drive modifications within populations of organisms generation after generation (microevolution), or by investigating patterns of changes on the tree of life over long periods of time (macroevolution). Understanding the ultimate drivers of morphological diversity eventually entails connecting microevolutionary processes with macroevolutionary patterns. My dissertation investigates the diversification of body and egg form and its drivers in a relatively small but particularly diverse insect order: the stick and leaf insects …

The Effects Humidity & Temperature Has On Dna Contamination During Storage, Samantha L. Ramey

Graduate Student Theses, Dissertations, & Professional Papers

Studies have been conducted on DNA cross-contamination throughout the criminal investigation process in order to evaluation the possibility that DNA from one sample could potentially influence the outcome of another. However, no published studies have examined the potential for contamination during the storage of genetic evidence after samples have been taken from crime scenes or suspects. This study is a continuation of a preliminary project, which examined storage drying time in relation to cross-contamination. The current study tested temperature and humidity for the potential of cross-contamination during storage prior to extraction. Prior to storage, 50 μl of male saliva was …

Quantitative Social Science Methods, Social Networks, And Scalar Mismatches: Advancing Social-Ecological Systems Science Towards Adaptation And Transformation, Holly Kathleen Nesbitt

Graduate Student Theses, Dissertations, & Professional Papers

The adaptive capacity of social-ecological systems to maintain resilience or undergo transformation is increasingly important for navigating global change. Although social interactions and ecological disturbances are often cited as an essential element of social-ecological systems, social interactions are often undertheorized and simplistic, and the relative effects of both social and ecological processes are rarely considered in tandem. In this dissertation, I work towards advancing social-ecological systems research by highlighting opportunities for improved quantitative social science methods, using structurally explicit methods to evaluate the mechanisms underpinning social interactions, and characterizing scalar mismatches in a social-ecological system experiencing a regime shift. In …

Grizzly bear attractant policies in Montana: how regulations, recommendations, and resources differ among and between recovery areas

Chairperson or Co-Chairperson: Alexander L. Metcalf & Chad J. Bishop

Abstract

Grizzly bears (Ursus arctos horribilis) are a keystone species and play an important role in their environment. After near extinction, the U.S. Fish and Wildlife Service implemented a recovery plan of six recovery zones to increase grizzly populations. Although these efforts allowed grizzly bear numbers to increase, so too have human-grizzly bear conflicts, significantly challenging agencies in charge of bear management. A concern …

Understanding The Underidentification Of Autism In Native American Students, Emily A. Brooke

Graduate Student Theses, Dissertations, & Professional Papers

School psychologists are called upon to promote nondiscriminatory practices that ensure equity and fairness for all youth, including racially minoritized students. Despite being overrepresented in almost every other disability category of special education, Native American students nationwide are underrepresented within the category of autism. The current study focuses on factors within educators that might lead to the underidentification of Native American students with autism. In alignment with the cultural humility model, and the tripartite model of multicultural competence embedded within it, the current study explored 36 educators’ attitudes, knowledge, and skills as they relate to the culturally responsive assessment of …

Characterizing Riverine Carbon: A Spatiotemporal Study Of Organic And Inorganic Carbon Variability And Evaluation Of Methods For Quantifying Pco2, Fischer Larson Young

Graduate Student Theses, Dissertations, & Professional Papers

Carbon is a critical component of aquatic ecosystems. For inland waters, carbon is a basal resource for biological communities and is a key component of trophic transfer through ingestion and respiration processes. Additionally, carbon acts as a key biogeochemical tracer that can track chemical, physical, and biological processes from the terrestrial landscape to inland waters to the ocean. Riverine carbon, however, can be challenging to characterize and interpret due to the complexity of its sources and sinks along a riverine continuum. Included in this work are the biogeochemically relevant forms of carbon such as dissolved inorganic carbon (DIC), the partial …

Toward A Dialectical Account Of Nature, Georgia Rae Grimm

Graduate Student Theses, Dissertations, & Professional Papers

The protection of nature has been a central aim of environmentalism for well over a century. However, the concept of nature has been subjected to abundant critiques in recent literature, threatening the conceptual tenability of this goal. In this paper, I discuss why I find the concept of nature too valuable to dismiss and offer an account of nature that I believe remedies existent critiques. In Chapter 1, I recount arguments for the protection of nature and illustrate their dualistic underpinnings. In Chapter 2, I discuss issues with dualistic accounts of nature and demonstrate why Steven Vogel’s monistic alternative is …

Applying Resource Selection Probability Function (Rspf) To Understand Floral Resource Use By A Common Bumble Bee, Bombus Vancouverensis, Rebekah Brassfield

Graduate Student Theses, Dissertations, & Professional Papers

Bumble bees (Hymenoptera: Bombus) are important pollinators in temperate ecosystems worldwide with seasonal caste variations involving queens, workers, and drones. Like all organisms, they must meet their nutrient requirements for successful growth and development by using several floral resources over time. When resource use is in greater proportion to its abundance on a landscape, that use is considered selective. To examine resource use within the context of abundance, a resource selection probability function (RSPF) was applied to examine floral resource use through a flowering season by a common bumble bee, Bombus vancouverensis. The RSPF framework was used to examine 1) …

Using Bone Biology To Enhance Forensic And Paleoanthropological Dna Analysis, Keith M. Biddle

Graduate Student Theses, Dissertations, & Professional Papers

We know that the optimal site for DNA extraction from human skeletal remains lies primarily in the petrous portion of the crania, and secondarily in the dental pulp, but we do not know why. As for the optimal location in the post-crania, targeted extraction sites are based on experience or inference, not empirical data. So, where to sample for DNA when only post-cranial elements are available? There are many instances where the petrous and/or teeth are not present or cannot be sampled. The three main goals of the project are 1- develop our foundational knowledge of the underlying cellular and …

Traversing Paradigms: An Environmental Journey To Body And Mind, Martin Ceja Mejia

Graduate Student Theses, Dissertations, & Professional Papers

Traumatic life experiences altered the way I perceive the world. As a result, I embark on a journey to reshape my relationship to self, the built and natural world; to environment. In this thesis I ask: How do I want to relate to the environment? Considering I am a doubly colonized agent, I also aim to decolonize my relationship to environment along the process. Therefore, this work aims to formulate a new, personal, relationship to environment through academic literature, history, psychology, Indigenous knowledge and science, and literary studies, among other fields of knowledge. This work is interdisciplinary in nature; life …

“The Long Arm Of The Dreaded B.I.”: The Bureau Of Investigation And The Origins Of The Federal Surveillance State, William Schuman-Kline

Graduate Student Theses, Dissertations, & Professional Papers

This thesis looks to analyze and understand how U.S. government officials created the first domestic intelligence agency in the United States: the Bureau of Investigation (BOI). In so doing, this paper examines how intelligence collection functioned within the U.S. prior to the creation of the BOI, what domestic and international concerns prompted the creation of a centralized institution like the BOI, and how the press, congressmen, and public opinion constrained the creation and early years of the BOI. This paper argues that from its onset, the Bureau of Investigation dedicated significant time and resources to surveilling American citizens for threats …

Seeding Resilience: An Examination Of The Impacts Of A Seed Saving Network In Western Montana, Christina Leas

Graduate Student Theses, Dissertations, & Professional Papers

Seed saving, a worldwide practice as old as agriculture, continues even in the context of an increasingly industrialized and globalized agricultural system. While some scholarship has focused on informal seed saving practices that continue to thrive in the global South, few studies have examined the dynamics of these practices in the global North, particularly in the American West. Informal seed saving systems have implications for the resilience of agroecosystems. The concept of resilience has become an important framework for conceptualizing agroecosystems as social-ecological systems, both in scholarship and in policy. However, operationalizing the concept of resilience, particularly in agroecology research, …

Trading Financial Instruments Like A Video Game: Searching For Profit Using Deep Reinforcement Learning., Sebastian Coombs

Graduate Student Theses, Dissertations, & Professional Papers

Buying and selling Stocks, Foreign Currencies (FOREX), Commodities, and Cryptocurrencies have been a source of wealth generation, and more often, wealth loss for many brave enough to enter the financial markets. In this paper, the author builds on the work of Williams, J. 2022 and develops an agent-based method to solve this wealth generation problem with the use of neural networks. The author points out some assumptions made by Williams, J. 2022 that were sound in theory, but made the implementation of the algorithm presented in their paper diverge from the theory. The author proposes a fundamentally different algorithmic method, …

Structural Mechanism Of Nuclear Receptor Biased Agonism, Michelle Deanna Nemetchek

Graduate Student Theses, Dissertations, & Professional Papers

Nuclear receptors are a class of ligand-activated transcription factors that affect gene expression. Pharmaceutical drugs that target nuclear receptors make up (13%) of all therapeutics prescribed in the United States. Unlike signaling pathways, nuclear receptors have a wide variety of binding partners that can bind upon activation of a nuclear receptor to upregulate gene transcription. These binding partner proteins, called “coregulators”, are diverse in function. However, the determinants of their binding to nuclear receptors, and how binding to certain coregulators over others occurs, is not known.

In this work, we examine how ligands create a preference for nuclear receptors to …
