Women’S Voices For The Earth: A Discourse Analysis Of Gendered, Environmental Media Advocacy, Marit Olson

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Women’s Voices for the Earth (WVE), a Missoula based, nationally recognized non-profit, empowers women to advocate against toxic chemicals that cause individual and community health hazards. There is little analysis of the intersection of women’s and environmental subjugation and how these intersections influence women’s environmental organizations. My research examines the influence of ecofeminist ideology, as framed by Karen Warren’s ecofeminist and class analysis, in WVE’s online discourse, primarily social media. To do so I apply a Foucaultian discourse analysis to WVE’s online publications, and compare that to an analysis of the online presence of Toxics Action Center (TAC), a non-gendered …

Wolf-Cougar Co-Occurrence In The Central Canadian Rocky Mountains, Ellen Brandell

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Cougars and wolves are top carnivores that influence the dynamics of an ecosystem, including prey behavior and dynamics, and interspecific competition. Studies about the interactions between wolves and cougars typically find wolves are dominant competitors to cougars. We examined single-species, single-season occupancy models and co-occurrence models of wolves and cougars in the Central Canadian Rocky Mountains to understand interactions between these two species on a grand landscape. Data was collected from 2012-2013 using remote wildlife cameras and separated into seasons. Naïve occupancy estimates were larger for wolves in both seasons, but both species had smaller ranges in winter. There were …

May You Walk In Beauty: The Decline Of Navajo Land And Culture, Jocelyn Catterson

Undergraduate Theses, Professional Papers, and Capstone Artifacts

The Navajo homeland, Dinetah, is bordered by four mountains that are sacred to the Navajo people: two in Colorado, one in New Mexico, and one in Arizona. Historically, Navajo medicine men have traveled to these mountains to renew prayers and collect medicinal herbs. Today, the mountains, which exist outside of the reservation boundaries, are used for resource extraction and various recreational pursuits. While many Navajo are fighting for the protection of these sacred lands and their traditional culture, others are disinterested. Traditional practices and beliefs are slowly disappearing within the Navajo Nation. The land-use issues associated with these sacred mountains …

Retinoic Acid Hydroxylase Inhibitors As A Novel Therapy For Alzheimer’S Disease, Isabel M. Makman

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Alzheimer’s Disease (AD) is one of the most prevalent neurodegenerative diseases afflicting the modern world. As no cure for AD has yet been discovered we sought to explore a potential treatment option based on the inhibition of retinoic acid (RA) metabolism, the active metabolite of vitamin A. Beta-amyloid plaques form in the brain and decrease cognitive function in AD patients. In a recent preclinical study RA was shown to decrease these plaques and rescue memory deficits in an Alzheimer’s mouse model[i]. One key limitation is that when RA is administered to humans it induces its own breakdown, making …

Global Response To Local Problems:The Global Health Community Response To The Ebola Outbreak Of 2014, Nicole Thelen

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Health crises are often met with much support from the global health aid communities, who strive to contain the current health crisis and improve the conditions of the affected society. The recent Ebola outbreak of 2014 is no exception. Driven by public panic and media coverage, the global health community responded in force, dispatching aid organizations, monetary help, and military assistance to both assist those affected with the disease and prevent it from spreading. The World Health Organization, along with Doctors without Borders and many other global organizations, swept in to provide aid to the affected areas. This project examines …

Crop Swap Missoula: Food Waste And The Sharing Solution, Cathryn Raan

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Rachel Botsman coined the term “collaborative consumption” to describe an economic model based on sharing, swapping, trading, or renting products and services, and enabling access rather than ownership¹. Also referred to as the sharing economy, the mesh economy, or the peer-to-peer economy, collaborative consumption models offer a more efficient use of unused, or underutilized resources. Whereas previously peer-to-peer exchanges were only practical within small networks of friends, family, and neighbors, the Internet and mobile technology have allowed us to share almost anything at any time. While there are countless examples of community exchange platforms, and more springing up …

Into The Wild: A Case Study Of The Intersection Of Archaeology And Federal Wilderness Policy, Erika S. Blecha

Graduate Student Theses, Dissertations, & Professional Papers

Cultural resource specialists working with and for Federal land management agencies have voiced their concern about the perception of cultural sites within federally recognized wilderness areas. However, as a whole, professionals working within the discipline of archaeology have remained relatively absent in the debates on wilderness with regards to human occupation in these designated areas. This thesis introduces the concept of wilderness, its history, perceptions, management, laws, and issues relevant to archaeology. It also draws attention to the paucity of archaeological research and the relaxed nature of cultural resource compliance mandates [National Historic Preservation Act (NHPA) Sections 106 and 110] …

Non-Coding Rnas Of The Q Fever Agent, Coxiella Burnetii, Indu Ramesh Warrier

Graduate Student Theses, Dissertations, & Professional Papers

Coxiella burnetii is an obligate intracellular bacterial pathogen that undergoes a biphasic developmental cycle, alternating between a small cell variant (SCV) and a large cell variant (LCV). Despite the remarkable niche and life cycle of C. burnetii, little is known about its modes of regulation and the roles that non-coding RNAs play in its growth and development. One such element is the intervening sequence (IVS); a 444-nt RNA element that is inserted within helix 45 of CoxiellaÆs precursor 23S rRNA. C. burnetii may have acquired IVS through horizontal transfer, and it has been subsequently maintained by all strains of C. …

Run To The Hills - Partial Migration In Large Herbivores, Wibke Peters

Graduate Student Theses, Dissertations, & Professional Papers

Partially migratory populations in which some individuals move to allopatric ranges during one season while others remain on their shared range, offer a unique opportunity to understand which factors shape the realized niche of individuals with plastic movement behaviors. For ungulates, forage and its spatiotemporal variability, risk (predation, humans) and density have been suggested to be the main determinants for the probability, distance and timing of migration. Roe deer (Capreolus caproelus), a small browsing ungulate with a high ecological plasticity and a wide distribution, present an ideal model species to test hypotheses on migration plasticity.

It's A Small World: Biogeography And Invasion In The Mouse Intestine, Ellen Lark

Graduate Student Theses, Dissertations, & Professional Papers

Host associated systems are of particular interest to many microbiologists because invasion of these systems can lead to disease. One important host-associated systems is the intestinal microbiome, but in many studies, including those on pathogenesis, this system is represented by samples from one location (generally the feces or cecum). This body of work was initiated in part because I wondered why a large and diverse ecosystem was being was being represented by samples from only one habitat.

The biogeography of living organisms has an impact on landscape ecology studies, including those in the field of invasion ecology. Despite several studies …

Engendering The Past: An Archaeological Examination Of The Precontact Lifeways Of Women At Yellowstone Lake, Yellowstone National Park, Cathy J. Beecher

Graduate Student Theses, Dissertations, & Professional Papers

This thesis examines three lines of evidence within the precontact archaeological record around Yellowstone Lake, focusing on elucidating female-specific lifeways. This work is undertaken as a means to explore concepts of gender within precontact archaeological contexts. This aim is accomplished using statistical analysis of lithic tool distribution patterns, ethnohistoric information on plants found through archaeobotanical assays and the microspatial examination of cultural fire features.

Variation in the use of obsidian and chert for unifacial tool manufacture indicates potential restrictions on the manufacture of gender specific tools as these stone resources become less available. In addition, a frame-of-reference is built by …

It Takes A Village: Placing Middle Rocky Mountain High Altitude Residential Sites Of The Late Prehistoric Firehole Phase Into A Broader Regional Context, Bryon Alan Schroeder

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation presents three separate articles in different stages of peer-review all focused on late Late Prehistoric (AD 1300 to contact) residential occupations, in the Wind River Range and Shirley Basin of Wyoming. These articles cover survey results in in the Wind River Range of Wyoming, Shoshone ethnic interpretations associated with Late Prehistoric artifact assemblages, and a lithic analysis from the excavated interior of domestic structure at an alpine and basin location of the Firehole Phase. These articles broaden the research agenda of high-altitude sites to downplay the role of ethnicity and include adjacent sites of the Wyoming Basin. In …

Dynamic Motions Of The Alpha Subunit Of Heterotrimeric G Proteins In The Nucleotide- And Ric-8a-Bound States, Labe Adam Black

Graduate Student Theses, Dissertations, & Professional Papers

The conformational changes and segmental dynamics involved in the G alpha-subunit of heterotrimeric G proteins have been investigated for 3 separate binding states by using binning-time-dependent single-molecule F÷rster resonance energy transfer (smFRET) of freely diffusing proteins and time-resolved fluorescence anisotropy. The bound states include Ric-8A (Resistance to Inhibitors of Cholinesterase-8A (Miller, Emerson et al. 2000; Miller and Rand 2000; Tall, Krumins et al. 2003)), a guanine nucleotide exchange factor (GEF), and nucleotides GDP and GTP. To analyze the smFRET data, energy transfer efficiency histograms were constructed at binning times varied from 1000 to 2,500 ╡s. Then the conformational equilibria and …

A Zooarchaeological Study Of Generational Decision-Making: Modeling Subsistence And Demographic Change In Late-Holocene Occupations Of Housepit 54 At The Bridge River Site (Eerl4), Mid-Fraser, B.C., Matthew Joseph Walsh

Graduate Student Theses, Dissertations, & Professional Papers

The Bridge River site is a winter pithouse village near the confluence of the Bridge and Fraser Rivers in the Mid-Fraser Canyon that was occupied periodically from as early as 1800BP to the mid-19th century. Prentiss et al. (2008) divide the range of occupations into four Periods: Bridge River (BR) 1, c. 1800-1600BP, BR2, c. 1600-1300BP, a short-lived BR3, c. 1300-1100BP (by the end of this period the village appears to have been largely abandoned), and BR4, a late reoccupation of the site, c. ~500 to 100BP (Prentiss et al. 2008, 2011, 2012). During BR2 and into BR3, between 1500-1100BP, …

The Habitat Of European Brown Bears In Northern Spain: Mapping Habitat Fragmentation And Potential Connectivity, Alma D. Pacheco

Graduate Student Theses, Dissertations, & Professional Papers

The European brown bear in northern Spain is considered to be an endangered species whose habitat has been fragmented into two subpopulations due to habitat loss and lack of connectivity. The importance of improving connectivity and preventing more habitat destruction is vital to recover the species in this region. This research looks at spatial and temporal variations of brown bear habitat by mapping the conditions of habitat fragmentation and potential connectivity at a regional extent. This research examines net changes of brown bear habitat fragmentation between 1990-2000, 2000-2006, and overall 1990-2006; and the degree of brown bear habitat connectivity between …

Cows And Plows: Science-Based Conservation For Grassland Songbirds In Agricultural Landscapes, Marisa K. Lipsey

Graduate Student Theses, Dissertations, & Professional Papers

Temperate grasslands are among earth’s most imperiled ecosystems. In North America, steep declines of endemic songbird populations indicate that grassland loss and degradation may be approaching critical levels. Grasslands are agricultural landscapes largely (~85%) under private ownership with little formal protection status. Remaining bird populations depend on grazing lands that have not been converted to cropland. We combine regional data from a hotspot for grassland bird diversity (northeast Montana, USA; 26,500-km2) with continental data spanning the northern Great Plains (1,000,000-km2) to evaluate how land use and management influence bird distribution and abundance. Regionally, habitat used by seven grassland specialists spanned …

Wilderness And Epistemic Wildness, John T. Stanfield

Graduate Student Theses, Dissertations, & Professional Papers

The traditional concept of wilderness was a product of the time out of which it came. Times have changed. The social context of conservation, how humans affect nature, and scientific understanding of how ecosystems function have all shifted in ways that make the wilderness idea problematic. The values that people found in wilderness are still relevant, however. It is the way that they are tied together in the concept of wilderness that has become a problem.

I propose a revised concept of wilderness that meets the concerns of critics of wilderness, and accounts for the tension between the wild and …

A Model For Determining Drivers Of Phenology In Western United States Rangelands, Joseph R. St. Peter

Graduate Student Theses, Dissertations, & Professional Papers

Plant phenology has long been used as an indicator of climate. Recent changes in plant phenology are evidence of the influence of climate change. Modeling plant phenology has become an effective tool to understand the impacts of climate change. Using machine learning techniques I developed a modeling process for accurately predicting phenology across a diverse landscape. This model uses individual site data to set site specific climate thresholds for plant phenology. This model also identifies the limiting factors to vegetation phenology for rangelands in the western United States. NDVI remotely sensed data was used to quantify land surface phenology and …

Sacred Zones: Examing Wilderness In Yellowstone, Maine And Russia, Lily S. Vonderheide

Graduate Student Theses, Dissertations, & Professional Papers

This thesis seeks to examine issues of resource conservation and recreational access in three regions of immense historical and ecological significance: Yellowstone National Park, the North Woods of Maine, and the protected nature reserve system of Siberia. By applying a combination of direct professional experience, current research and ongoing environmental policy action, the thesis attempts to provide an accurate picture of current and future challenges facing the three regions. Part I, “Yellowstone Paradox,” traces the roots of Yellowstone’s restrictions on recreational boating access in a post-WWII discourse of consumer recreation, the development of a sustainability ethic and its deployment as …

La Manzana Mordida: Sexo Y Religión En El Cine De Luis Buñuel, Micaela Downey

Graduate Student Theses, Dissertations, & Professional Papers

La extensa y variada obra fílmica de Luis Buñuel permite observar la repetición obsesiva de motivos, imágenes y objetos que constituyen lo que podría denominarse el universo personal de Buñuel. La proliferación de zapatos, pies, cajas misteriosas y armas de fuego (sin olvidar los tambores de Calanda, los insectos y las gallinas) ha atraído la atención de la crítica convirtiéndolos en objetos detallados de análisis. Este ensayo no intenta proponer una “obsesión” más, sino reparar en un motivo que, a pesar de su recurrencia (y, por lo tanto, de su importancia) ha pasado inadvertido: la reescritura de la historia bíblica …

The Last Wolves Of Isle Royale, Kasey Rahn

Graduate Student Theses, Dissertations, & Professional Papers

Isle Royale National Park, located in Michigan, is home to a wolf population that is in decline due to complications from inbreeding. Scientists and managers struggle to decide whether to intervene. Some scientists promote bringing new wolves to the island to restore the population because they say the decline is human-caused. Others promote “watchful waiting.” To date, the National Park Service has not interceded and is currently undergoing a management planning process. The issue raises questions about what it means to manage wildlife in an era of change. Should humans intervene to protect wildlife in the face of climate change …

The Drunken Path: Discerning Women's Voices And Participation In The Informal Economy Of Illegal Manufacturing Of Prohibition Alcohol In The Historical And Archaeological Record, Kelli M. Casias

Graduate Student Theses, Dissertations, & Professional Papers

This thesis puts the Prohibition years in Anaconda and Butte, Montana, into historical, and sociocultural context to discover an engendered narrative of liquor law violators between the years 1923 and 1926 and to investigate the scope of the local informal, illegal, illicit economic systems dictating the distribution of illegal liquor during that era. The transference of the means and modes of production, as envisioned by Karl Marx, and collective social resistance serve as the theoretical frameworks for analysis and examination of three case studies. The first, Poacher Gulch is a remote mining site in western Montana, was the subject of …

Linking The Effects Of Risk Factors On Annual Calf Survival To Elk Population Dynamics In The Bitterroot Valley, Montana, Daniel R. Eacker

Graduate Student Theses, Dissertations, & Professional Papers

The recolonization of gray wolves (Canis lupus) in multiple carnivore systems has been correlated with declining recruitment of juvenile ungulates, but the importance of wolves relative to other established carnivores is uncertain. The realized effect of carnivores may depend on compensation from forage and winter weather severity, which may mediate juvenile vulnerability to predation. Also, in high predation systems, the importance of juvenile recruitment may be reduced for ungulate population dynamics. We first tested for the effects of risk factors on annual elk (Cervus elaphus) calf survival and estimated cause-specific mortality rates. Secondly, we investigated the …

Maximal Femoral Artery Blood Flow During Cycle Ergometry, Tucker W. Squires

Graduate Student Theses, Dissertations, & Professional Papers

MAXIMAL FEMORAL ARTERY BLOOD FLOW DURING CYCLE ERGOMETRY

Chairperson: Matthew Bundle Ph.D.

The delivery of oxygen to working muscle in order to support aerobic respiration has long been recognized as one of the critical elements conferring endurance performance. Oxygen is transported from the environment to the active cells by the cardiovascular system, which is classically understood to deliver progressively greater amounts of gas to support increased levels of aerobic metabolism. However, the vast majority of existing studies have used modes of exercise that activate relatively small volumes of muscle and consequently have relatively small demands for oxygen delivery. We measured …

Selective Solid Phase Extraction Of Uranium Using An Aminophosphonic Acid Functionalized Composite Material, Ranalda Tsosie

Graduate Student Theses, Dissertations, & Professional Papers

Uranium is an element of interest because it is an abundant source of concentrated energy. In 1948 the US offered money for uranium ore mined in the US, which created a mining boom in the southwest that included the Navajo Reservation. During the late 1960s the demand for uranium decreased and many mining operations shutdown and left behind a legacy of contamination. As a result many Navajo communities have numerous water sources that exceed established maximum contamination levels for uranium and other toxic metals. These contaminations are a direct result of abandoned Cold War uranium mines and mill waste sites …

The Regulation Of Mucosal Immunity By Inflammatory Mediators, Bryan Joseph Simons

Graduate Student Theses, Dissertations, & Professional Papers

Despite massive efforts to develop effective therapeutic options for the treatment of asthma, disease prevalence continues to increase. Approximately 300 million people worldwide have been estimated to be affected by asthma, and it remains a leading cause of childhood hospitalization. While environmental as well as genetic causative agents have been identified, the heterogeneous nature of the disease has proven difficult to effectively treat. Asthma is characterized as chronic inflammation of the airway characterized by increased airway hyperreactivity, increased goblet cell hyperplasia, and airway remodeling. While these effects are traditionally regarded to be mediated through the actions of CD4+ Th2 cells, …

An Investigation Of The Impact Of Ipad Usage On Elementary Mathematical Skills And Attitudes, Grant Patrick Swicegood

Graduate Student Theses, Dissertations, & Professional Papers

Currently, many schools are implementing one-to-one initiatives, where the goal is to give every student in a classroom a tablet or laptop computer. However, there is a dearth of research backing up the assumption that they significantly improve student learning. This study explored the effects of these new instructional devices by focusing on two second-grade classrooms implementing a one-to-one iPad program. Specifically, it investigated how iPad usage affects student and teacher attitudes toward mathematics, student mathematics performance in and out of app environments, the instructional purposes for which iPads are used in the classroom, and implementation issues of the technology. …
