Using Satellite Observations Of Soil Moisture To Improve Modeling Of Terrestrial Water Cycles, Colin W. Brust

Graduate Student Theses, Dissertations, & Professional Papers

Terrestrial evapotranspiration (ET) describes the flux of water from the Earth’s surface to the atmosphere, calculated as the sum of evaporation from soil and leaf surfaces, and transpiration through plant stomata. ET is the largest terrestrial water flux, returning over half of the precipitation that falls on land back to the atmosphere, annually. Additionally, ET plays a key role in Earth’s carbon, water, and energy cycles, linking them together via the movement of water and CO₂ through plant stomata. Because of its important role in these Earth system processes, it is essential that existing methods of measuring and modeling …

A Deep Learning Approach To Mapping Irrigation: U-Net Irrmapper, Thomas Henry Colligan Iv

Graduate Student Theses, Dissertations, & Professional Papers

Accurate maps of irrigation are essential for understanding and managing water resources in light of a warming climate. We present a new method for mapping irrigation and apply it to the state of Montana over the years 2000-2019. The method is based on an ensemble of convolutional neural networks that only rely on raw Landsat surface reflectance data. The ensemble of networks method learns to mask clouds and ignore Landsat 7 scan-line failures without supervision, reducing the need for preprocessing data or feature engineering. Unlike other approaches to mapping irrigation, the method doesn't use other mapping products like the Cropland …

Decoupled Diel Solutes: Linking Primary Production And Nitrate Uptake In A Montane Stream, Kimberly Bray

Graduate Student Theses, Dissertations, & Professional Papers

Tight coupling of surface water diel dissolved oxygen (DO) and nitrate-N (NO₃-N) signals reflects stoichiometric demand of carbon and nitrogen in stream ecosystems. However, DO and NO₃-N can become decoupled due to alternative drivers of diel solutes, resulting in conflicting estimates of stoichiometric and modeled NO₃-N uptake. In this study, I measured benthic biomass, hydrology, and dissolved solutes in a montane stream located in western MT over a growing season (June-October 2019). Daily stream metabolism and NO₃-N uptake were modeled using a single-station open-channel approach. Timing and amplitude of key diel signals …

The Built Environment At Plaza H, Cahal Pech: A Study In Resiliency, Rachel A. Steffen

Graduate Student Theses, Dissertations, & Professional Papers

This thesis seeks to understand the human response to extreme environmental, social, and political change during the Terminal Classic (750-1050 CE) at Cahal Pech. Across the Maya lowlands, this period is distinguished by the end of divine kingships, the cessation of new monumental architecture, rapid changes in prestige goods and trade networks, and population decline at many major centers. Cahal Pech, a medium-sized ceremonial center, experienced great shifts in political power and access to resources during the Terminal Classic. This thesis attempts to understand the last occupation of the site, prior to abandonment. Field data for this study is derived …

Worth A Dam: Glacier View And The Preservation Of Wild America, Shawn Patrick Bailey

Graduate Student Theses, Dissertations, & Professional Papers

Conceived in the mid-1930s and formally proposed in 1943, the Glacier View Dam was an Army Corps of Engineers’ proposal for the North Fork of the Flathead River in northwestern Montana. This 416-foot tall dam would have provided inexpensive hydroelectric power to the region and helped control flooding on the volatile Columbia River watershed. Glacier View would also have flooded 20,000 acres of Glacier National Park, one of the “crown jewels” of the national park system. An ideologically diverse coalition of National Park Service officials, wilderness activists and outdoor recreation enthusiasts organized the defense of Glacier National Park and convinced …

Water For Fish And Farms: An Examination Of Instream Flow Programs In Montana Using Spatially-Explicit Water Rights Data, Anna Leigh Crockett

Graduate Student Theses, Dissertations, & Professional Papers

The state-level institutions governing water use in the western United States have increasingly come under pressure and scrutiny related to their inability to navigate water use conflicts in recent decades. Rapid population growth and shifting public values towards leaving water instream for recreational and environmental purposes pose challenges to Montana water supplies which are predominantly allocated for irrigated agriculture. Additionally, while water scarcity and unpredictable availability are not new dilemmas in Montana, the rate at which climate change is driving shifts in the distribution, timing, and availability of water supplies is unprecedented. Current water policies may not be nimble enough …

Heat For The Masses: Thermal Ecology Of The Western Tent Caterpillar, Victoria Dahlhoff

Graduate Student Theses, Dissertations, & Professional Papers

A unique feature of some gregarious, colonial insects is their ability to create external structures that alter environmental conditions for the entire (often family) group. A combination of physical alteration of local microhabitats and behavioral thermoregulation allows many of these animals to actively control their body temperatures, which allows them to regulate energy use and metabolism in variable thermal environments. Here I describe mechanisms of microhabitat modification and thermal regulation in the western tent caterpillar, Malacosoma californicum pluviale. Tent caterpillars build communal silk tents, whose temperatures can rise substantially above ambient air temperature. I experimentally manipulated colony sizes and examined …

Tribal Consultation Policy And Practice:A Case Study Of The Confederated Salish And Kootenai Tribes And Nmisuletkʷ (The Middle Fork Of The Clark Fork River) As A Tribal Trust Resource, Jennifer J. Harrington

Graduate Student Theses, Dissertations, & Professional Papers

Formal, government-to-government Consultation between sovereign nations is a process of continuous relationship-building, a partnership and an agreement made with all points-of-view included in the process, with results that have the fingerprint of all nations involved evident. The Federal Government is obligated to work with Federally-recognized Tribes as sovereign nations in matters that have or will impact each Nation’s people and places (reservations, treaty-protected areas)—a process legally known as Consultation. The Environmental Protection Agency (EPA), as a federal agency, must uphold the Federal Trust responsibility which includes the act of Consulting with Federally-recognized Tribes on matters involving human health and the …

Descriptive Statistic Characteristics Study For Level 4 Frontier High Schools In Montana, Jacqueline May Gorshe

Graduate Student Theses, Dissertations, & Professional Papers

Frontier high schools in Montana have a degree of isolation that presents unique challenges setting them apart from their rural, and especially their urban, counterparts. Unfortunately, a one-size-fits-all approach hinders their voices being heard in professional development and policy decision making. This dissertation provides a profile of these high schools and their communities using four social determinants of health: education, access to health care, economics, and behavioral risk factors through mixed methods approach with descriptive statistics and high school principal survey responses. The results of this approach revealed frontier high schools have small class sizes and low teacher-student ratios, but …

Modeling Twitter Sentiment As A Function Of Particulate Matter 2.5 For Communities Impacted By Wildfire Across Montana And Idaho, Matthew Kelly

Graduate Student Theses, Dissertations, & Professional Papers

Fine particulate matter (PM2.5) is a known pollutant with clinically detrimental physiological and behavioral effects. We consider Twitter sentiment as a potential indicator for well-being in communities impacted by wildfire-associated PM2.5 across Montana and Idaho spanning 5 years (2014-2018). From these geospatial air quality data and geo-tagged tweets, we trained county level models to examine the power of Twitter sentiment as a function of PM2.5. For all 24 counties sampled, we found between 1 and 8 affective dimensions where a positive �� 2 was detected with a significant F-statistic (�� < 0.05). Specifically, we show that sentiment for anticipation in the wildfire-prone county of Missoula, MT yielded respective training/test set �� 2 of 0.0958 and 0.0686 with a p-value for the F-statistic of 3.09E-07. These analyses support social media sentiment as a potential public health metric by showing one of the first observations of a relationship between PM2.5 and Twitter sentiment.

Attribution Of Soil Surface Temperature Sensitivity To Hydro-Climatic Drivers, Sarah Khalid, Marco Maneta

Graduate Student Theses, Dissertations, & Professional Papers

Greenhouse gas emissions caused by human economic activity are altering the global hydrologic cycle and the energy exchanges at the land surface. In large portions of the western US there is evidence of reduced summertime precipitation and increased air temperatures and longwave irradiation. At local scales, these changes can translate into more frequent and intense extreme land surface temperature events during the summer, with potential impacts on wildfire activity, forest health, soil biochemical cycles, and thermal comfort for human populations. However, because increases in radiation and sensible heat (air temperature) inputs to the land surface are confounded with changes in …

The Impact Of Bullying Participant Role On The Relationship Between School Climate And Attitudes Towards Interpersonal Peer Violence, Miriam Rose Baker Reynolds

Graduate Student Theses, Dissertations, & Professional Papers

Positive school climate has been linked to lower levels of school violence and interpersonal conflict. Interventions that impact school climate have been shown to powerfully impact school violence and bullying prevalence. The current study used data collected from three middle schools in the same Rocky Mountain town. The survey tool contained items asking students about their behaviors when confronted with interpersonal conflict such as bullying, their attitudes towards interpersonal conflict, and their perceptions of their school’s climate. Significant differences were found between genders on attitudes towards interpersonal peer violence but no differences were found in the distribution of genders across …

Community-Centered Sustainable Conservation And Ecotourism Planning In The Bossou Forest Reserve, Guinea, West Africa, Destina Samani

Graduate Student Theses, Dissertations, & Professional Papers

Ecotourism management has evolved over the years towards responsible conservation of the natural environment, sustaining the well-being of local people, enriching personal experiences and increasing environmental awareness. The development of a forest reserve is characteristic of the management–visitor–host community interface and the attendant competing interests in the face of new challenges, ideas and theories. In particular, host community participation in the conservation of the forest space tends to breakdown under weak ecotourism management, partly evident by the imbalanced exploitation of ecosystem services resulting in wildlife and society’s inability to cope effectively with the changes (Walker et al., 2016).

The Bossou …

The Kite And The String: Why Philosophy Needs More Storytellers, Mason James Voehl

Graduate Student Theses, Dissertations, & Professional Papers

This thesis seeks to explore the relationship between philosophy and storytelling as grounded in their shared task of instructing readers in how to live a rich and moral life. Using a combination of narratives and the philosophical theories of Martha Nussbaum, Edward Mooney, and Iris Murdoch, I claim that philosophy and storytelling ought to be natural allies rather than territorial enemies as each reveals and attends to separate but equally important aspects of the good life in community with others. I then extend this claim into the context of environmental philosophy, using the work of writer Jason Mark as an …

Protecting Natural Resources On Agricultural Lands: Producers' Perspectives On The Conservation Stewardship Program In Montana, Mary Ellis

Graduate Student Theses, Dissertations, & Professional Papers

Industrial agricultural production contributes to some of the most significant environmental problems in the United States today. Scientists have identified agricultural production as a primary cause for the decline of native species, soil degradation, and water pollution in the U.S. In response to this crisis, grassroot organizations crafted, and got Congress to pass, the Conservation Stewardship Program (CSP), a federal program aimed to incentivize producers to increase on-farm conservation practices. CSP is designed to serve as a space for producers to gain access to financial and technical support, test out new practices, and provide a platform to discuss best practices …

"Fenced-In Place": White Settler Colonialism As Opposition To Increased Tribal Management Of The National Bison Range, Brittany Lee Palmer

Graduate Student Theses, Dissertations, & Professional Papers

Since the Tribal Self Governance Act was passed in 1994, the Confederated Salish and Kootenai Tribes (CSKT) in western Montana have sought increased management responsibilities at the National Bison Range, which is fully encompassed by the Flathead Indian Reservation. Though the U.S. Fish and Wildlife Service has managed the Bison Range since it was established in 1908, the Tribes assert that they were the original stewards of bison in the area, and have requested both the reinstatement of the National Bison Range to Tribal trust ownership and increased management responsibilities through negotiated Annual Funding Agreements with the Department of Interior. …

Gendered Melancholy In Lolita: Reading Into Humbert Humbert’S Dolorous Haze, Joseph D. Brookbank

Graduate Student Theses, Dissertations, & Professional Papers

This paper argues that in Lolita, the narrator Humbert Humbert uses the subject-position of the great male melancholic in order to, at the discursive level, (re)perform violent acts of appropriation against Dolly’s body, subjectivity and representation. Humbert attempts to translate the loss and waste which he brings about into perverse sorts of gain; these gains relate to processes such as catharsis, compensation, redemption, regeneration, a sense of exceptionality, and aesthetic/erotic/artistic enjoyment. The project has an introduction and two sections. The introduction demonstrates how Humbert enters into the male melancholic subject-position in order to perform his sorrow in a way that …

3D scanning and Printing have become useful in many scientific fields over the last few years, and Physical Anthropology/ Archaeology is not an exception. With skeletal collections decreasing all over the globe and the question of preservation on the rise, it has become necessary to look towards different methods in which one can obtain important information. 3D scanning has become useful over the last few decades and therefore it is important to establish where this new technology can be of use. This paper will bring 3D scanning and printing into question and determine whether this technology should be used in …

Statistical Modeling Of Influenza-Like-Illness In Montana Using Spatial And Temporal Methods, Benjamin A. Stark

Graduate Student Theses, Dissertations, & Professional Papers

Studying air pollution and public health has been a historically important question in science. It has long been hypothesized that severe air pollution conditions lead to negative implications in basic human health. Primarily, areas thats are prone to severe degrees of human pollution are the focus of such studies. Such research relating to less populated areas are scarce, and this scarcity raises the question of how such pollution dynamics (human-made and natural) influence human health in more rural areas.

The aim of this study is to explore this hole in research; in particular we explore possible links between air pollution …

Reconnecting Indigenous Knowledge To The Sunlight Basin: Integrating Traditional Ecological Knowledge And Archaeology, Liz Dolinar

Graduate Student Theses, Dissertations, & Professional Papers

Traditional ecological knowledge (TEK) specific to plants has been developed over long-term connections to the environment, diligent observations, and practical experience by Indigenous communities. The traditional ecological knowledge of Indigenous peoples is a vital source for the contextualization and further understanding of past human environmental relationships in the Sunlight Basin of northwestern Wyoming. The Eastern Shoshone people, among many other groups, traditionally occupied the Sunlight Basin of northwestern Wyoming, a region of the Greater Yellowstone Ecosystem. There is a growing necessity for collaboration with Indigenous populations within archaeological and anthropological research. The aim of this project is to develop a …

"How About The Tariff And Homestead?" Homestead, Tariff Rhetoric, And Wage Insecurity In 1892, Paul T. Thompson

Graduate Student Theses, Dissertations, & Professional Papers

Members of Congress appropriated the 1892 labor conflict at Homestead, Pennsylvania as a point of partisan rhetorical debate over the ills or benefits of the 1890 McKinley Tariff. This appropriation demonstrated how congress found the tariff in general useful not only for engaging public concerns over industrial era woes like wage insecurity, but also for deflecting public discussion away from an underlying federal helplessness to mitigate those same detrimental effects of industrial capitalism.

Dna Integrity In Forensic Samples, Samantha L. Ramey

Graduate Student Theses, Dissertations, & Professional Papers

When packaged genetic evidence samples are stored in close proximity, there is a higher chance for cross-contamination, which can lead to potential false results. The goal of this study was to test DNA storage methods and environments to determine the best way to avoid potential cross-contamination. Established protocols for storing different types of genetic evidence samples were evaluated: biological swabs and DNA cards. A known concentration of pig DNA was introduced to the evidence samples. Three different evidence drying times of the DNA-free swabs and cards were implemented before packaging: immediate packaging, an hour drying, and 24 hours drying. The …

Mapping Ideologies: Place Names In Glacier National Park, Kaitlin E. Pipitone

Graduate Student Theses, Dissertations, & Professional Papers

This thesis examines the intersection of place names and language ideologies. In particular, I identify and analyze the emergent language ideologies in discussions about place names in six written sources related to Glacier National Park. I propose that the authors construct language ideologies about place names through the three semiotic processes identified by Irvine and Gal (2000): iconization, fractal recursivity, and erasure. Further, I argue that language ideologies have historically authorized choices about place names on the basis of linguistic differentiation.

Examining six written sources, the publication of which span nearly a century, I identify several excerpts in which authors …

Adaptive Potential To Camouflage Mismatch: Plastic And Evolutionary Responses To A Climate Change Stressor, Marketa Zimova

Graduate Student Theses, Dissertations, & Professional Papers

Animals that occupy temperate and polar regions have specialized traits that help them survive in harsh, highly seasonal environments. One particularly important adaptation is seasonal coat colour (SCC) moulting. Over 20 species of birds and mammals distributed across the northern hemisphere undergo complete, biannual colour change from brown in the summer to completely white in the winter. But as climate change decreases duration of snow cover, seasonally winter white species (including the snowshoe hare Lepus americanus, Arctic fox Vulpes lagopus and willow ptarmigan Lagopus lagopus) become highly contrasted against dark snowless backgrounds. The negative consequences of camouflage mismatch and adaptive …

Probing Denatured State Conformational Bias In 3-Helix Bundles With Foldable Or Intrinsically Disordered Domains, Moses Joseph Leavens

Graduate Student Theses, Dissertations, & Professional Papers

Protein misfolding is associated with several life threatening diseases – Alzheimer’s, Parkinson’s, Cystic fibrosis, Sickle cell anemia, and the Transmissible spongiform encephalopathies, to include Chronic Wasting disease, Scrapie, and Creutzfeldt-Jakob disease. To provide insight into protein misfolding, it is beneficial to understand how an amino acid sequence encodes structure. Once thought to behave as random coil polymers under denaturing conditions, an abundance of recent evidence suggests denatured proteins retain ‘non-random’ or residual structure, which may bias a protein chain to fold efficiently to its native conformer. Probing energetics of residual structure in denatured proteins is challenging, given the shortage of …

Managing Just World Beliefs In An Unjust World For Victims Of Sexual Violence, Lindsey Chatfield Grove

Graduate Student Theses, Dissertations, & Professional Papers

The foundational expectations for good things to happen to good people, while bad things happen to bad people, is referred to as the belief in a just world (BJW) hypothesis (Lerner, 1980; 1966). The understanding is that BJW is a deep-rooted belief that when challenged with injustice, an individual implements strategies in order to protect this core belief from shattering (Lerner, 1980). BJW has long explained victim blaming (Hayes, Lorenz, & Bell, 2013; Jones & Aronson, 1973) and a positive relationship with psychological protection for injustice to self (L Bègue & Bastounis, 2003; Lerner & Simmons, 1966; Sutton & Douglas, …

Treating Trauma Within Rural Schools: An Implementation Science Perspective, Heather Marie Halko

Graduate Student Theses, Dissertations, & Professional Papers

High rates of childhood trauma exposure (65-75%) are concerning given the negative outcomes associated with trauma-related symptoms. Numerous evidence-based practices (EBPs) have been developed to treat posttraumatic stress symptoms; however, schools often experience barriers to implementing these interventions with fidelity. Given the scarcity of service options within rural areas, this qualitative study explored factors that might influence the adoption and implementation of trauma-focused interventions within rural schools using the Consolidated Framework for Implementation Research (CFIR; Damschroder et al., 2009) and the Implementation Outcomes Framework (IOF; Proctor et al., 2011). A semi-structured protocol was used to interview clinicians working in rural …
