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 …

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 …

Golden Eagle Resource Selection And Environmental Drivers Of Reproduction In The Northern Range Of Yellowstone National Park, David Brown Haines

Graduate Student Theses, Dissertations, & Professional Papers

In the United States (US), National Parks are considered the “crown jewels” of protected lands. However, the importance of National Parks to wildlife populations and the species that inhabit them is not often quantified, thus, requiring a better understanding of National Parks as a conservation tool. Golden eagles (Aquila chrysaetos) are a North American species of conservation concern and territories in the northern range of Yellowstone National Park (YNP) are relatively dense. However, average reproductive rates over the past ten years (2011-2020) have been low (productivity = 0.34, nest success = 28%). The contrast of high density and …

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 …

“Meet Them Where They're At”: Faith-Based And Secular Homeless Outreach Approaches, Larissa K. Fitzpatrick

Graduate Student Theses, Dissertations, & Professional Papers

Many organizations strive to provide resources for individuals experiencing homelessness both in and outside of shelters. Studies analyzing the effects of religiosity on the practices of homeless shelters show that both faith-based and secular shelters generally offer a variety of services, from the accommodative, such as food and shelter, to the restorative, like housing, substance-use rehabilitation, and spiritual transformation (Snow and Anderson 1993). Although both types of shelters may require clients to participate in the latter to access the former, faith-based shelters often show a belief-based rigidity, with many requiring prayer, sermon attendance, or a proclamation of faith to access …

Perceived Threat And Left-Wing Authoritarianism: The Effect Of Framing On Persuasive Messages, James Donald Mcfarland

Graduate Student Theses, Dissertations, & Professional Papers

Past research reveals a strong connection between feeling threatened and Right-Wing Authoritarianism (RWA). This relationship is considered to be an integral part of authoritarianism and the nature of its presence in the left-leaning populace is still being fully explored. This study examined the relationship between perceived threat and Left-Wing Authoritarianism (LWA) through the framing of persuasive messages. Participants (n = 256) were recruited through Amazon’s Mechanical Turk (MTurk) and given a list of reward- or threat-framed statements concerning the possible ramifications of voting in future elections and then asked to rate the quality and persuasiveness of the respective statements. …

Semivariogram Methods For Modeling Whittle-Matern Priors In Bayesian Inverse Problems, Richard David Brown

Graduate Student Theses, Dissertations, & Professional Papers

We present a new technique, based on semivariogram methodology, for obtaining point estimates for use in prior modeling for solving Bayesian inverse problems. This method requires a connection between Gaussian processes with covariance operators defined by the Matérn covariance function and Gaussian processes with precision (inverse-covariance) operators defined by the Green’s functions of a class of elliptic stochastic partial differential equations (SPDEs). We present a detailed mathematical description of this connection. We will show that there is an equivalence between these two Gaussian processes when the domain is infinite which breaks down when the domain is finite due to the …

Geometric morphometrics has become a more popular method in anthropology as three-dimensional data and research become more widely recognized and accessible. This research provides a refined method utilizing 3-D geometric morphometric analysis to determine sex from the human pubic bone. The study used a sample of N=378 individual pubic bones from the University of New Mexico Maxwell Documented Collection. Eight landmarks were digitized on each individual bone using a Microscribe Digitizer. Results from the Principal Components Analysis provide promising clustering between male and female groups, as well as indications that the method may be ancestry-specific, and that parity may have …

College Athletes And Alcohol Use: The Need For Effective Prevention/Intervention Programs, Paige M. Craig

Graduate Student Theses, Dissertations, & Professional Papers

The literature review investigates the relationship between alcohol and college athletes. College athletes are a high-risk drinking group; alcohol use amongst collegiate athletes is a major concern due to the consequences associated with use. It is important to review student-athlete behavior and influences that contribute to alcohol use in order to design a program that effectively prevents use and intervenes use when it occurs. Results from original articles were used to support the need for effective prevention/intervention programs for this population based on the severity and frequency of use, negative effects of alcohol, and lack of effective prevention/intervention programs. Coaches, …

Mathematical Creativity And Problem Solving, Brooke Gruntowicz

Graduate Student Theses, Dissertations, & Professional Papers

Many mathematical problems can only be solved in routine ways. But when students see that problems can be solved in innovative, original, or novel ways, unexpected benefits arise such as development in one’s mathematical creativity. The general mathematics classroom must be reformed into a more perceptive atmosphere that challenges all students, where student mathematical creativity is fostered, and creative insights are encouraged. Mathematical creativity encourages the full development of the learner, all students on the spectrum from underchallenged to traditional. Mathematical creativity is the ability of "divergent production in mathematical situations, and the ability to overcome fixations in mathematical problem …

Chemical concentrations of antidepressants have increased over the years steadily building in surface waters globally. These drugs have had various impacts on the animals tested, such as impacts on movement, motivation, and reproduction. In order to further investigate the effects of the antidepressant fluoxetine, male Betta splendens were exposed to the drug. These fish are naturally aggressive for reproduction purposes and have easily observable aggressive responses to other male fish. These characteristics make them a good model for studying Fluoxetine’s impact on reproduction, motivation, and movement. Males in this study were primed with either a female or empty chamber prior …

Managing Forest Disturbances: Effects On Mule Deer And Plant Communities In Montana's Northern Forests, Teagan Ann Hayes

Graduate Student Theses, Dissertations, & Professional Papers

Mule deer (Odocoileus hemionus) are frequently the focus of population and habitat management in the western United States. Land and wildlife managers use disturbance to reset forests to earlier successional stages and improve the quality and quantity of forage available to mule deer. However, the effects of management practices on nutrition and selection vary widely, so the implementation of management practices raises ecological as well as management-related concerns. This work investigated how disturbance from wildfire, prescribed fire, and timber harvest influences the spatial and temporal distribution of nutritional resources in mule deer summer range, and therefore, how the …

Flowers From The Devil: An American Opiate Crisis, The Criminalization Of Marijuana, And The Triumph Of The Prohibition State, 1840-1940, Clinton David Lawson

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation focuses on historic changes in public perception of narcotic use and abuse from the mid-nineteenth century to the mid-twentieth. From the 1840s to the outbreak of Civil War, politicians, physicians, the general public, and state and federal government remained largely ambivalent on the topic of drug use. Opium, morphine, and cannabis were legal, widely available in American pharmacies, and touted as essential medicines. Within the Bohemian community, artists and writers experimented with the recreational use of cannabis and their accounts of that style of consumption filled the pages of Harper’s, The New Yorker, and a host of other …

Influence Of Livestock And Electrified Fences On Livestock Depredation And Habitat Selection By Grizzly Bears In The Mission Valley, Montana, Kari Lynn Eneas

Graduate Student Theses, Dissertations, & Professional Papers

Balancing protection between livestock and carnivores has been a long-standing challenge in conservation. When encounters between carnivores and livestock or humans result in conflict or livestock depredation, the safety of both wildlife and humans are at risk. Reducing livestock depredation by grizzly bears (Ursus arctos horribilis) will be important as populations continue to recover and expand beyond public lands in the Northern Continental Divide Ecosystem. We used GPS locations from 8 female grizzly bears spanning 5 years in the Mission Valley, Montana, to evaluate the effect of livestock on habitat selection of grizzly bears. The Mission Valley is located on …

Ethical Eating: Overcoming Alienation In The Industrial Food System By Aligning Our Practices With Our Principles, André Kushnir

Graduate Student Theses, Dissertations, & Professional Papers

This thesis arose out of a moment of discord, while an environmental philosopher was eating blackberries in the middle of a blizzard in Missoula, Montana. What follows is an attempt to bridge the gap between our principles and our practices, by asking the questions: What does ethical eating look like? Is it possible within our current industrial food system? and If not, what needs to change? Responding to the publication of the 2019 EAT-Lancet report, this essay moves beyond thinking of ethical eating as “healthy” and “sustainable” and challenges the networks of suffering and labour that we take for …

Characterizing Burn Severity Of Beetle-Killed Forest Stands Leveraging Google Earth Engine-Derived Normalized Burn Ratios, Sofronio Catalino Propios Iii

Graduate Student Theses, Dissertations, & Professional Papers

Following numerous studies, a general consensus on burn severity in forests affected by bark beetle outbreaks has not yet been achieved. The purpose of this study is to characterize burn severities in forest stands affected by mountain pine beetle (MPB) outbreaks, especially in relation to “time since outbreak”, vegetation cover, and topographic factors. This study focuses on wildfires that occurred in the northern Rocky Mountains of Idaho and Montana during the 2012 fire season within forested areas that had previously experienced prior MPB outbreaks. Remote sensing techniques were used to quantify and compare the burn severities of MPB-outbreak stands with …

An Exploration Of Zero Waste Policies And Recommendations For Missoula, Sarah Blyth Lundquist

Graduate Student Theses, Dissertations, & Professional Papers

“Zero Waste” is a concept and community goal that has arisen to challenge the current consumerist economic system and offer solutions for a number of environmental issues. In adopting this goal, individuals and communities pledge to reduce and divert at least 90% of their waste in a certain number of years. These goals can be reached by employing policies, programs, and other intervention tactics which establish Zero Waste infrastructure, ensure equitable and widespread access to Zero Waste services, and provide educational outreach and resources to the community. Missoula adopted a Zero Waste goal in 2016 and created a Zero Waste …

Alas, Poor Yorick: A Dna Analysis Of Ancestry Using Crania, Claire Hanson

Graduate Student Theses, Dissertations, & Professional Papers

Current methods for estimating ancestry in biological profiles provided to law enforcement and forensic collections rely heavily on the use of metric and non metric methods such as FORDISC 3.1 and “trait lists.” The reliance on these methods has led to inaccurate and ambiguous ancestry estimations, as many metric and non metric methods are subjective and cannot be statistically tested for error rates. As a result, forensic collections, such as the University of Montana Forensic Collection, could potentially house remains that have been inaccurately curated. In order to test the accuracy of curation in the UMFC, DNA samples were extracted …

Bird And Native Bee Responses To Habitat Treatments, Emily Bea Oja

Graduate Student Theses, Dissertations, & Professional Papers

As forests across the United States have been altered due to fire suppression in the last century, their structure has been altered, resulting in increased fuel loads. Subsequently, managers have been increasingly implementing habitat treatments including prescribed burning, mechanical thinning, and a combination of both treatments to reduce fuel loads and enhance habitat for ungulates. The Rocky Mountain Elk Foundation has partnered with agencies to complete over 10,000 of these treatments across the United States to enhance elk habitat. As treatment impacts to other wildlife species are not well understood, we evaluated the effects of these treatments on the bird …

N-­‐Heterocyclic Anthryl Isoxazole Amides (Aims) Bind Quadruplex Dna And Exhibit Robust Antitumor Activity, Matthew Jacob Weaver

Graduate Student Theses, Dissertations, & Professional Papers

Using the structure-activity relationship emerging from previous reports, and guided by pharmacokinetic properties, new AIMs have been prepared with both improved efficacy against human glioblastoma cells and cell permeability as determined by fluorescent confocal microscopy. We present our first unambiguous evidence for telomeric G4-forming oligonucleotide anisotropy by NMR resulting from direct interaction with AIMs, which is consistent with both our G4 melting studies by CD, and our working hypothesis. Finally, we show that AIMs induce apoptosis in SNB-19 cells.

The Phenotypic Flexibility Of Thermogenic Capacity: From Physiological Mechanism To Evolutionary Implications, Maria Stager

Graduate Student Theses, Dissertations, & Professional Papers

Individuals face many selection pressures that change throughout their lives. Phenotypic flexibility, the ability to flexibly and reversibly modify a trait value, is one way an individual can optimally match its phenotype to the prevailing environmental conditions. In this dissertation, I used juncos as a lens to understand the causes of variation in flexibility within physiological systems and among individuals. In my first chapter, I investigated how Dark-eyed Juncos (Junco hyemalis) alter mechanisms of heat production and heat conservation to cope with variation in ambient conditions. My results demonstrate the ability of birds to adjust thermoregulatory strategies in response to …
