Comparing Fence Modeling And Mapping Approaches To Support Wildlife Management And Research In Southwest Montana, Simon Albert Buzzard

Graduate Student Theses, Dissertations, & Professional Papers

Fences pose significant challenges to wildlife movement, but their effects are difficult to quantify because fence location and fence type data are lacking on a global scale. We developed a fence location and density model in southwest Montana, USA to provide data to researchers and managers, and test whether previous models could be applied to a new region and retain suitable levels of statistical accuracy. Our model used local expert opinion to inform how road, land cover, and ownership spatial layers interacted to predict fence locations. We validated the model against fence data collected on random 3.2 km road transects …

Resource Selection And Calving Success Of Moose In Colorado, Forest P. Hayes

Graduate Student Theses, Dissertations, & Professional Papers

Across much of North America, moose populations (Alces alces) are declining due to disease, predation, climate, and anthropogenic pressures. Despite this, populations of moose in Colorado have continued to grow. Studying successful (i.e., persistent or growing) populations of moose can facilitate the continued conservation of the species by identifying habitat features critical for moose persistence.

First, I evaluated calving success of moose in Colorado and the impact of willow habitat quality and nutrition. I then estimated the probability of female moose having a calf using repeated observations in a Bayesian occupancy model. I assigned values for dry matter …

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 …

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 …

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 …

Modeling Hydrologic Impacts Of Tribal Water Rights Quantification And Settlement On The Flathead Indian Irrigation Project, Jordan Andrew Jimmie

Graduate Student Theses, Dissertations, & Professional Papers

The Confederated Salish and Kootenai Tribes (CSKT) of the Flathead Reservation are a federally-recognized group of tribes (Kootenai, Salish, and Pend d’Oreille) located in western Montana. On the reservation lies the expansive Flathead Indian Irrigation Project (FIIP), which supplies irrigation water to approximately 127,000 acres of tribal and non-tribal agricultural land. The 1904 Flathead Allotment Act opened “surplus” land to non-native homesteaders without tribal consent, initiating the land ownership fragmentation observed on the reservation today. This legacy, combined with historically unquantified tribal reserved water rights and the antiquated state of the FIIP infrastructure, including water losses from unlined earthen canals, …

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.

Investigation Of Docosahexaenoic Acid As A Potential Treatment For Particulate-Induced Inflammation, Paige Lynn Fletcher

Graduate Student Theses, Dissertations, & Professional Papers

Acute and chronic inflammation are vital contributing factors to pulmonary diseases which can be triggered by the exposure to airborne toxicants such as crystalline silica (SiO2) and nanomaterials. There has been an increasing trend in the use of nanomaterials; specifically multi-walled carbon nanotubes (MWCNT), in various consumer products that in turn will increase the risk of pulmonary diseases. Unfortunately, there is a lack of preventative and therapeutic treatments for these diseases. A potential treatment that has been shown to have anti-inflammatory effects is the common dietary supplement docosahexaenoic acid (DHA); an omega-3 polyunsaturated fatty acid most commonly found in fish …

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 …

Prioritizing Parcels For Conservation Easements Using Least-Cost Path Analyses Of Land Ownership: Case Study Within Theorized Grizzly Bear Migration Corridors Of Western Montana, Joseph H. Offer

Graduate Student Theses, Dissertations, & Professional Papers

As the world’s human population has grown and converted large natural habitats to human dominated landscapes, the planet’s biodiversity has decreased. To combat the loss of biodiversity from human development, many conservation professionals champion the concept of conservation corridors between intact habitats. Conservation corridors, made up of protected land, serve as a connection for wildlife populations to intermix genetics and, subsequently, help reduce the risk of extinction. The ideal geographic location of corridors is generally determined through geographic information system modeling using biophysical conditions and theorized animal movement. However, the resulting corridors are often expansive and protecting entire corridors is …

Impacts Of Trogocytosis-Mediated Intracellular Signaling On Cd4+ T Cell Effector Cytokine Production And Differentiation, Steven James Reed

Graduate Student Theses, Dissertations, & Professional Papers

Trogocytosis is the direct intercellular transfer of membrane and membrane associated molecules. Unlike other passive-membrane transfer events, trogocytosed molecules may remain fully functional and become re-expressed on the surface of the trogocytosis-positive (trog+) recipient. This phenomenon commonly occurs between various cell types, including those of the immune system. CD4+ T cell trogocytosis occurs during their activation by antigen presenting cells (APC). Consequently, the acquired molecules include ligands for signaling receptors on the T cell.

The impacts of CD4+ trogocytosis on the immune response are largely unknown. While it has been demonstrated that trog+ cells can present trogocytosed peptide:MHC (pMHC), and …

An Exploration: How Voluntourism Conservation Projects Coordinate With And Contribute To Conservation Efforts In Madre De Dios, Peru, Alejandrina R. Ocanas

Graduate Student Theses, Dissertations, & Professional Papers

Mirroring trends in international tourism, alternative tourism, and ecotourism, the voluntourism industry has grown, developed and diversified significantly since 2005. Scientific attention to voluntourism has grown, too, focusing mainly on participant motivations and outcomes. However, explicit research on the outcomes and impacts voluntourism projects generate for their host communities and environments is sparse. As voluntourism becomes increasingly frequent, it is critical to design and implement projects that maximize potential for positive impacts and minimize negative impacts. This study reaches toward that goal by investigating (1) the operational characteristics of voluntourism conservation projects in Madre de Dios, Peru, a global conservation …

Developmental, Ecological, And Life History Influences On Predator-Induced Plasticity In Songbirds, James Christopher Mouton

Graduate Student Theses, Dissertations, & Professional Papers

Predation is a ubiquitous ecological force that plays a major role in the evolution of phenotypes. Where the predation risk is predictable and variable, prey species are expected to evolve plasticity in traits that reduce the likelihood of being killed and eaten by predators. Such plasticity may be especially critical for the survival of dependent offspring because they are particularly vulnerable to predators and suffer high levels of predation across taxa. Yet the fitness effects of predator-induced plasticity can vary across life stages, differ between parents and offspring, or be mediated by interactions with other species in the community. The …

Local Knowledge And Climate Information: The Role Of Trust And Risk In Agricultural Decisions About Drought, Adam J. Snitker

Graduate Student Theses, Dissertations, & Professional Papers

Climate change is projected to dramatically impact agricultural production across the world. Agricultural producers must adapt to changing conditions by implementing practices and utilizing knowledge that creates resilient operations. This study explores how Montana farmers and ranchers use of different types of knowledge during periods of drought and how risk perceptions and trust influence the use of knowledge. To understand the role trust and risk in producers’ use of local knowledge and climate information, I conducted five focus groups with 34 Montana agricultural producers. Producers explained that they encounter many agriculture-related risks, including uncertain forecasts, financial losses, and adverse weather. …

Patterns Of Wildfire Risk In The United States From Systematic Operational Risk Assessments – How Risk Is Characterized By Land Managers, Erin Kathleen Noonan-Wright

Graduate Student Theses, Dissertations, & Professional Papers

Since the turn of the 21st century, the complexity and costs of wildfires have increased substantially. There is a need to evaluate entrenched fire management practices that encourage status quo decision making to suppress fires. Data stored in mandated reporting systems collected during wildfires may provide a perspective on fire management decision-making needed to change wildfire governance structures. The Relative Risk Assessment (RRA) resides within a federally mandated workflow process necessary for all longer duration federal wildfires since 2010. Land managers rate hazard, probability and values at risk as high, moderate or low throughout the course of an incident to …

Methods For Analyzing High Dimensional Data With Applications To The Wearable And Microbiome Data Analysis, Quy Xuan Cao

Graduate Student Theses, Dissertations, & Professional Papers

Modern studies in medicine, epidemiology, pharmacy and other fields generate high dimensional data. We developed statistical analysis methods for two types of such data: activity and microbiome data. Specifically, reliable measures of the frequency, duration and intensity of physical activity provided by wearable technology were used in the analysis of activity data. Accelerometry-derived measures of physical activity were compared with established predictors of 5-year all-cause mortality in older adults, aged between 50 and 85 years from the 2003- 2006 National Health and Nutritional Examination Survey, in terms of individual, relative, and combined predictive performance. A total of 33 predictors of …

Methods For Estimating Mountain Goat Occupancy And Abundance, Molly Mcdevitt

Graduate Student Theses, Dissertations, & Professional Papers

Abundance and occupancy are two parameters of central interest to the field of ecology. Furthermore, accurate (both precise and unbiased) estimates are key pieces to the puzzle of effective wildlife management decision-making. While there exist a variety of sampling techniques and statistical models for effectively estimating population parameters for frequently encountered and large mammals, methods for sampling unmarked and rare species are few and far between. The first step to acquiring usable parameter estimates is through the use of sampling theory and incorporation of probabilistic sampling designs to collect count-data and occurrence-data. Often, it is assumed that probabilistic sampling designs …

Investigation Of The Tribal Park Concept And Opportunities For The Blackfeet Nation, Iree Schmautz Wheeler

Graduate Student Theses, Dissertations, & Professional Papers

The Tribal Park model is an emerging tool being used by indigenous groups in the United States and Canada for the management of unique and sacred natural areas, in some cases setting aside existing indigenous owned land, and in others regaining control of land management decisions in traditional territory. Currently in North America there are several sites that have self-identified as Tribal Parks. There is a lack of research regarding Tribal Park development in North America, which creates challenges for indigenous groups interested in pursuing a conservation designation of this type. Using an analysis of five Tribal Park case studies …

Jubah And Nashoba: An Artful History, Theodore Cecil Decelles

Graduate Student Theses, Dissertations, & Professional Papers

This creative dissertation unites art and history by writing a play using extensive historical research. The main body of work focuses on events surrounding the Natchez Revolt of 1729. The Natchez nation and colonial Louisianans attempted to accommodate each other by reaching a middle ground. Nonetheless, incivility culminated in a massacre at Fort Rosalie. The Natchez experienced profound sociopolitical changes that resulted in a downgrade of female power. North American history asserts many female chiefs interacted with colonial male leaders. Even so, female chiefs have remained at the margins of history. This creative work focuses on the hidden history behind …

A Structural And Biochemical Study On Ric-8a, An Intracellular Guanine Nucleotide Exchange Factor And Folding Chaperone For The Inhibitory G-Protein Alpha Subunit-1, Baisen Zeng

Graduate Student Theses, Dissertations, & Professional Papers

Heterotrimeric G-proteins (Gαβγ) regulate many cellular processes in the G-protein signaling pathways. The α-subunit (Gα) in the heterotrimer is activated by G-protein-coupled receptor (GPCR) as the guanine-nucleotide exchange factor (GEF), which catalyzes the GDP-release and GTP-binding reactions at Gα nucleotide-binding site, at the cell membrane. Intracellular GEFs for Gα subunits have been identified; among them, the mammalian isoform A of resistance to inhibitors of cholinesterase-8 (Ric-8A) catalyzes nucleotide exchange and functions as a folding chaperone for inhibitory Gα (Gαi1). In a nucleotide-free complex with Gαi1, Ric-8A likely assumes the GEF and chaperone roles by inducing a molten globule-like state. Tall …
