Metabolic And Cardiovascular Marker Alterations During Critical Training In Wildland Firefighters, Shae Gurney

Graduate Student Theses, Dissertations, & Professional Papers

Introduction: Wildland firefighters (WLFFs) are confronted with numerous physical and mental stressors. Pre-fire season includes an intense 2-week critical training (CT) period; a preparatory phase of multiple activities that can result in injury, illness, and rhabdomyolysis. The purpose of this study was to identify physiologic changes in metabolic, inflammatory, and oxidative stress biomarkers during 2 weeks of CT in WLFFs.

Methods: Eighteen male (29.4 ± 1.1 yr, 182.1 ± 1.6 cm) and three female (26.7  2.6 yr, 169.5  4.2 cm) participants were recruited from a Type I interagency hotshot crew and monitored over their 2-week CT. Fitness was …

Muscle Soreness And Damage During Wildland Firefighter Critical Training, Katherine Sue Christison

Graduate Student Theses, Dissertations, & Professional Papers

Introduction: Wildland firefighters (WLFF) undergo a critical training (CT) period immediately before the firefighting season. The intensity of CT exercise could lead to muscle damage, as previously reported cases of rhabdomyolysis in WLFFs have been documented. This study established the effects of activities performed during a two-week CT period on acute markers of muscle damage in WLFFs.

Methods: 18 male and 3 female Type I Interagency Hotshot WLFFs were studied during a 14-day critical training period. Upper- (US) and lower-body (LS) muscle soreness and daily body weight (BW) scales were collected. Venous blood was collected on Days 1, 4, 8, …

Social Climatology: An Age Comparison Of Women's Sustained Commitment To Collective Action Against Climate Change, Sara A. Humphers-Ginther

Graduate Student Theses, Dissertations, & Professional Papers

Climate activists urgently emphasize action to prevent catastrophic and apocalyptic-like damage from climate change. The foundation of the institutional change needed to combat climate change is collective action, which I study here through a collective action frame. These frames can gain traction for policy agendas: they are solution- and action-oriented. I interviewed women climate activists to understand how they frame the problems from, causes of, and solutions to climate change, as well as how they urge others to act against climate change. I compared my informants based on age because beliefs, values, and lived experiences are important in how activists …

Learning From Wilderness Fire: Restoring Landscape Scale Patterns And Processes, Julia Kittleson Berkey

Graduate Student Theses, Dissertations, & Professional Papers

Wilderness areas, because they are managed to be “untrammeled by man,” often offer the best approximation of intact, undisturbed ecological patterns and processes. In the case of wildland fire, this means that wilderness areas often provide the only landscapes where fire has been managed to play an active, ecosystem role. As a result, these wilderness areas offer unique lessons both in terms of wildland fire management as well as the ecological consequences that result from this management approach. For these reasons, an in-depth history of fire management in the wilderness areas of the Northern Rocky Mountains is provided to highlight …

Electrospun Fibers With Smart Delivery Of Therapeutic Agents, Zahra Mahdieh

Graduate Student Theses, Dissertations, & Professional Papers

Electrospinning is the most widely studied technique of producing fibers. Delivery of nanoparticles and therapeutic agents from electrospun fibers have potential uses in various fields including drug delivery, filtration, and cosmetics. However, controlling the delivery rate remains the main challenge. In the current study, core-shell structure fibers were developed with zinc oxide nanoparticles applied in the shell composition to improve the pore structure (release pathway) and mechanical stability. Fine-tuned delivery rates were achieved via loading different sizes of silver nanoparticles (Ag NP) inside the fiber core. In vitro drug release assays showed fast, slow, and intermediate delivery rates of 20 …

Collaborative Conservation: A Philosophical Analysis Of The Efficacy And Commensurability Of Tek And Western Science, Anne M. Belldina

Graduate Student Theses, Dissertations, & Professional Papers

This thesis seeks to explore the similarities and differences between traditional ecological knowledge and Western science as a way to address long-held misconceptions about the efficacy of traditional ecological knowledge, or TEK. The motivation for this project arose from a deep desire to investigate the historical injustices toward Indigenous peoples in the name of conservation. The goal of this analysis is to illustrate that effective collaboration between Indigenous knowledge holders and Western scientists is not only possible, but desirable. I outline three major barriers from which I draw out three minimum criteria which much be met if collaborative conservation efforts …

The Role Of Experiential Learning In Developing Multicultural Competence, Kaoru Allison Powell

Graduate Student Theses, Dissertations, & Professional Papers

Although much importance has been placed on training programs to develop multiculturally competent service providers, the question remains as to when and where clinicians acquire their multicultural competence (MCC). Currently, most training programs appear to focus on the development of multicultural awareness and knowledge, without adequate focus on skills. However, experientially based learning exercises are associated with skills development in many areas, including general clinical skills development. Thus, students who engage in higher levels of experiential learning in their multicultural training may rate themselves as more competent with multicultural skills than students with less frequent experiential learning. I hypothesize that …

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 …

Organizational Influence On Knowledge Co-Production, Evora Dakota Glenn

Graduate Student Theses, Dissertations, & Professional Papers

Interdisciplinary and transdisciplinary approaches are needed to effectively address the challenges facing our complex social-ecological systems. To meet this need, many approaches, including co-production, have been proposed to overcome the difficult relationship between science and governance, often termed a ‘gap’, which can continue to impede natural resource problem solving. Co-production is an iterative process that engages scientists, managers, and community members in knowledge creation and problem solving. Evidence indicates that participants are more likely to view co-produced knowledge as more salient, legitimate, and credible, and that they are more likely to use it. Evidence also indicates that this iterative and …

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 …

Finding Fishers: Determining The Distribution Of A Rare Forest Mesocarnivore In The Northern Rocky Mountains, Jessica M. Krohner

Graduate Student Theses, Dissertations, & Professional Papers

The Northern Rocky Mountain fisher population (Pekania pennanti), is classified as a Species of Greatest Conservation Need and is of special concern to state, federal, and tribal entities. In this thesis, we present methods to effectively survey fishers across the northern Rockies of Idaho and Montana, and provide estimates of fisher distribution at a population range-wide scale through occupancy analyses. We also assess factors that influence fisher occurrence through covariate analyses and identify core fisher habitat in the northern Rockies through spatial occupancy modeling. By sampling broadly across the landscape, we provide baseline distributional data for comparison against …

The Home As A Site Of Family Communicated Narrative Sense-Making: Grief, Meaning, And Identity Through “Cleaning Out The Closet”, Kendyl A. Barney

Graduate Student Theses, Dissertations, & Professional Papers

This study utilized communicated narrative sense-making theory to explore the process of sorting through a deceased loved one’s belongings and changing the home after loss (referred to as “cleaning out the closet”), as the site of family communication and storytelling. Through storytelling, families make order of the disordered experience that is bereavement by negotiating meaning, identity, and family. The stories told about and within the process of “cleaning out the closet” elicit rich insight on each family’s experience with bereavement, loss, and life with each other. “Cleaning out the closet” narratives shed light on the interactions that occur between family …

Creating A Conservation Corridor In Coastal Ecuador: Constraints And Opportunities For Integrative Agroforestry, Lucille M.F. Rice

Graduate Student Theses, Dissertations, & Professional Papers

Agroforestry has the potential to address land degradation and rural livelihood concerns resulting from tropical deforestation and has therefore become a popular tool for reforestation in conservation initiatives. However, these initiatives often lack the resources to implement an integrative approach to developing site-specific agroforestry systems, leading to undesirable outcomes such as lack of community support and unmet ecological objectives. This paper presents a case study of a conservation initiative implemented by the Ceiba Foundation for Tropical Conservation (CFTC) in the Ecuadorian province of Manabí. The CFTC is working with private landowners to establish a coastal conservation corridor through reforestation and …

Selection Of Forage And Avoidance Of Predation Risk By Partially Migratory Mule Deer, Collin Jeffrey Peterson

Graduate Student Theses, Dissertations, & Professional Papers

Migration by ungulates has traditionally been thought of as a strategy that increases access to forage quality or reduces exposure to risk of predation, but the benefits of migration may be waning globally. In partially migratory populations, the persistence of both migrant and resident strategies is an intriguing ecological phenomenon, because migrants and residents often face contrasting fitness consequences. Partial migration is common in mule deer (Odocoileus hemionus), a species that has experienced widespread declines across the western United States during recent decades. Mule deer seldom switch between migratory strategies throughout their lifetime, which may make them less resilient to …

Optimizing The Use Of Wildlife Monitoring Resources, Charles Raymond Henderson Jr.

Graduate Student Theses, Dissertations, & Professional Papers

Accurate knowledge regarding trends in the abundance of wildlife populations provides a foundation for the understanding of wildlife ecology and effective wildlife management. Abundance estimates enable managers and researchers to track the status of wildlife populations, supply information on which to base wildlife management decisions, and provide a metric to assess the outcome of specific management actions. Consequently, accurate estimates of abundance provide essential knowledge for managing wildlife populations effectively. However, the amount of resources available for monitoring wildlife populations is limited and often fluctuates in response to changes in annual budgets. Therefore, agencies responsible for the management of wildlife …

Rhetoric And Perception: A Case Study Of The Proposed Northmet Mine On Minnesota’S Iron Range, Sophia J. Frank

Graduate Student Theses, Dissertations, & Professional Papers

Northern Minnesota is rich in natural resources, perhaps most uniquely the expansive mineral deposits of the Mesabi and Vermilion Ranges. The steel and taconite mining opportunities along these veins helped facilitate the rapid growth and infrastructure development of the area and is an important part of the identity of the region northwest of Duluth, aptly known as Iron Range. In addition to iron deposits, The Iron Range contains large deposits of copper and nickel. Recently proposed copper-nickel mining projects by PolyMet and Twin Metals have garnered a great deal of public controversy, especially around issues of economic revitalization of the …

Dynein Light Chain 1 Functions As A Cofactor For Post-Transcriptional Mrna Regulation And Rna Granule Assembly, Nicholas Day

Graduate Student Theses, Dissertations, & Professional Papers

Gene regulation is essential for ensuring maintenance, proliferation, and proper development of a cell. RNA binding proteins (RBPs) regulate gene expression by targeting and binding mRNAs to control their translation and often localize to cytoplasmic assemblies of protein and RNA called RNA granules to facilitate post-transcriptional mRNA regulation. Using C. elegans as a model organism, we report on the function of dynein light chain 1 (DLC-1), a subunit of the dynein motor complex, in post-transcriptional mRNA regulation in the gonad. Previous work suggests that DLC-1 is an RBP cofactor that functions independent of the dynein motor. It is unknown how …

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 …

Global And Regional Perspectives On Large-Landscape And Transboundary Conservation, Sanober R. Mirza

Graduate Student Theses, Dissertations, & Professional Papers

With the growing pressure of environmental degradation and exploitation to social and ecological landscapes around the world, conservationists are looking for new approaches to address the complex nature of transboundary issues. Large-landscape conservation supports conservation and management of ecosystems, wildlife, and resources in a more holistic approach that extends beyond protected area boundaries. Transboundary conservation, a distinct form of large-landscape conservation, operates across political and spatial scales by involving two or more countries cooperating to protect a border resource or ecosystem. Though the recognition of large-landscape and transboundary conservation is growing, there is limited understanding of trends across these types …

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 …

Biotic And Abiotic Drivers Of Acyclic Snowshoe Hare Population Dynamics In A Spatiotemporally Complex System, Alexander Vishvamitra Kumar

Graduate Student Theses, Dissertations, & Professional Papers

Although periodic fluctuations in species abundance have long fascinated society (e.g. lemming mass migrations and locust plagues in Egypt), it was not until 1924 that Charles Elton brought cycles to the attention of the scientific community. Following his work, cycle dynamics have remained an enigmatic area of ecology with many cyclic species exhibiting dampened and even acyclic dynamics across space (i.e. portions of their range) or time. One such species, snowshoe hares, exhibit drastic population fluctuations in the northern boreal, but are thought to exhibit dampened cyclic or acyclic population dynamics in the southern portion of their range with quantification …

Protecting Biodiversity On National Forests: The Evolution And Implementation Of Forest Planning Regulations, Anna Wearn

Graduate Student Theses, Dissertations, & Professional Papers

In 2012, the U.S. Forest Service (USFS) promulgated new forest planning regulations that significantly altered national forest management. One of the most controversial and important advancements was the inclusion of what were meant to be stronger biodiversity protections. An analysis of USFS’s rationale in revising the biodiversity regulations provides insights into how to interpret the substantively and procedurally new ecosystem and species protections. Examining this regulatory history reveals three key changes to the manner in which national forests are required to manage and monitor biodiversity: 1) a greater reliance on science to inform planning, 2) a new emphasis on ecological …

Down The Deer Path: Reflections On The Future Of Hunting In America, Jackie A. Bussjaeger

Graduate Student Theses, Dissertations, & Professional Papers

This collection of chapters delves into the dramatically shifting landscape of hunting sports from a personal perspective of a young hunter. As older hunters age out of the sport, hunter-funded conservation initiatives are in danger of losing support. This work examines the nature of relationships between hunters, their prey, and their worldview, as well as the elements of hunting that appeal to new hunters, and the challenges they may face as they become the hunters of the future.

Food Web Effects Of Lake Trout (Salvelinus Namaycush) Invasion In Northwestern Montana, Charles Wainright

Graduate Student Theses, Dissertations, & Professional Papers

Around the turn of the 20th century, lake trout (Salvelinus namaycush) were widely introduced in several lakes and reservoirs outside their native range in western North America. Since then, lake trout have become problematic in many lakes where they were introduced, causing significant declines in popular sport fishes and native species, most notably federally protected bull trout (Salvelinus confluentus). Despite evidence that invasive fish can cause cascading trophic effects in aquatic communities, the impacts of lake trout introduction / invasion on aquatic food webs remain poorly understood. Moreover, native fish restoration programs tend to focus on suppression …

Characterizing The Requirements For The Matricellular Protein, Dccn, In Nervous System Function, Elizabeth L. Catudio Garrett

Graduate Student Theses, Dissertations, & Professional Papers

The brain is organized as a complex network of specialized neurons that communicate via a combination of electrical and chemical signals. Our brains function to generate movement, control organ function, or direct complex behaviors; all of which requires the ability to regulate the flow of communication between circuits and networks. Work in this thesis addresses two areas of neuron communication: first, how does the release of more than one neurotransmitter from a single neuron impact behavior, and second, are matricellular proteins (MCPs) key contributors to synaptic transmission and neuron function? The conserved CCN family of MCPs have a …

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.
