The Hare And The Hawk: Predator, Prey, And Coat Color Mismatch In A Polymorphic Snowshoe Hare Population, Amanda Shuler Emmel

Graduate Student Theses, Dissertations, & Professional Papers

Climate change effects on predator-prey interactions are complex and poorly understood, with few study systems that explicitly connect specific antipredator traits to particular climate drivers. Such a system can be found in seasonal coat color change, whereby 21 species globally molt from a summer brown to a winter white coat to maintain camouflage with seasonal snow. Snowshoe hares (Lepus americanus) contend with increased predation due to climate-change induced coat color mismatch under decreasing snowcover. Through a combination of field experiments in the central Cascade mountains, my thesis investigates snowshoe hare mismatch and predation risk from both a predator …

Influence Of Cross-Country Skiing & Off-Leash Dogs On Wildlife Habitat Use In Lubrecht Experimental Forest, Sophie Ann Morris

Graduate Student Theses, Dissertations, & Professional Papers

Outdoor recreation activities are seen as a type of anthropogenic stressor that can significantly impact wildlife. Despite winter recreational activities having a more negative effect on wildlife compared to summer or aquatic recreation, they are the least studied in terms of impact (Larson et al., 2016). Wildlife species can be influenced both temporally and spatially by the development of winter recreation trails and snow-based recreation (Braunisch et al., 2011; Olsen et al., 2018). This research combines natural and social science methods to assess how cross-country skiers affect wildlife activity patterns, guiding decisions about managing recreation. During two winter data collections, …

An Investigation Of Three Rehabilitation Models On Cognitive-Linguistic And Psychosocial Well-Being Outcomes For Stroke Survivors With Chronic Aphasia, Jenna Ray Griffin

Graduate Student Theses, Dissertations, & Professional Papers

Aphasia, a typically chronic language impairment that impacts expressive and receptive language but does not impact intelligence, occurs in approximately 30 - 40% of stroke survivors. Chronic aphasia negatively impacts functional communication, communicative participation, and psychosocial well-being in stroke survivors. Access to care during the post-acute phase of recovery is limited, requiring novel models of rehabilitation that are person-centered and holistic. The intensive comprehensive aphasia program (ICAP) model has shown proof-of-concept, feasibility, and acceptability to improve patient cognitive-linguistic outcomes, psychosocial well-being, and communicative participation. However, outcomes from an ICAP have not been compared to usual care aphasia therapy or to …

Wildfires, Climate, And Equity: Towards Sustainable Forest Management And Conservation, Mark Regier Kreider

Graduate Student Theses, Dissertations, & Professional Papers

Forest and conservation sciences are both fields that inherently combine land and people, concerning topics such as the wildfire crisis, impacts of human-caused climate change on ecosystem functioning, and inequity of access to outdoor spaces. The research and science communication in this PhD dissertation explore these issues, integrating the biophysical and social sciences to promote understanding, stewardship, and conservation of human-forest systems. Chapter 1 assesses how humans shape patterns of fire through fire suppression, inadvertently ensuring that fires occur under the most severe conditions and effectively selecting for high-severity fire occurrences. Chapter 2 uses a wilderness area with a fire …

Habitat Selection And Connectivity Of Mountain Lions (Puma Concolor) Across Anthropogenic Barriers On The Olympic Peninsula: A Multi-Method Comparison, Thomas R. Barbee

Graduate Student Theses, Dissertations, & Professional Papers

Designing and maintaining effective wildlife corridors is an increasingly important conservation challenge in today’s fragmenting landscapes. GPS-based resource selection functions and camera-based occupancy models are both well-established staples of wildlife connectivity analyses and corridor planning, but each have notable trade-offs in cost and data resolution. Wildlife organizations worldwide rely heavily on camera-based occupancy modelling to plan wildlife corridors, especially where resource limitations or ethical concerns prohibit the use of GPS tags. If spatial connectivity maps from occupancy models could be shown to capture the essential elements of animal movement well enough to identify functionally equivalent corridors to those identified in …

A Comparison Of Concurrent Training And Moderate Intensity Continuous Training In Patients With Coronary Artery Disease, Amanda Alfaro-Chaverri, John Quindry, Charles Dumke, Brian Loyd

Graduate Student Theses, Dissertations, & Professional Papers

Moderate intensity continuous training (MICT) is the most studied method in cardiac rehabilitation (CR) for patients with coronary artery disease (CAD). Traditionally, resistance training has been utilized as a secondary role in CR. Recent interest in the topic suggests that MICT and resistance training should be applied collectively, an approach termed concurrent training (CT). The collective understanding of the potential of CT in CR patients is currently lacking.

Purpose: The aim of this professional paper is to analyze scientific evidence regarding the efficacy and safety of CT versus MICT. The analysis will focus on five primary measurements: exercise capacity, cardiovascular …

This study explores and maps an ancient, historic, and contemporary travel corridor that follows the San Joaquin River in the Central Sierra Nevada of California. It is called the Nium or People’s Trail by the North Fork Mono Tribe, the French Trail in historic archives, and the Mammoth Trail on contemporary US Forest Service maps. When I agreed to the request by Chairman Ron Goode of the North Fork Mono Tribe to map the Nium Trail, I was saying yes to a different, more broad and inclusive approach than I had previously taken as an archaeologist documenting archaeological sites and …

A New Frontier Of Responsibility: Children's Attributions Of Moral Responsibility To Autonomous And Controlled Robots, Thomas M. Macko

Graduate Student Theses, Dissertations, & Professional Papers

A prevailing theory in moral psychology, known as the Theory of Dyadic Morality, proposes that we evaluate moral transgressions primarily through weighing the mental states and intentions of both the perpetrator and the victim of a given transgression. Previous research has found adults and children similarly refer to mental states and intentions when making moral evaluations as third-party observers of a moral transgression. How might this framework apply to social robots, who arguably lack the mental states and intentions we can effortlessly identify in humans? The present study sought to examine how children view a social robot as culpable for …

A Replicating Rna Vaccine For Crimean-Congo Hemorrhagic Fever Virus Protects Via Non-Neutralizing Anti-Nucleoprotein Antibodies And Trim21, Shanna Star Leventhal

Graduate Student Theses, Dissertations, & Professional Papers

Crimean-Congo Hemorrhagic Fever Virus (CCHFV) is a negative-sense, tick-borne bunyavirus endemic to Europe, Asia, and Africa. CCHFV may cause a severe hemorrhagic disease with a case fatality rate of 5-70% and, to date, there are no widely available or highly efficacious vaccines or therapeutics. Because of its widespread distribution and lack of countermeasures, the WHO has listed CCHFV as a high priority pathogen.

Here, we report a self-replicating, alphavirus-based RNA vaccine that expresses the CCHFV nucleoprotein (repNP) and glycoprotein precursor (repGPC). Initial studies showed that repNP induces high titers of non-neutralizing anti-NP antibodies while repGPC stimulates a robust T-cell response. …

The Genetic Basis Of Two Reproductive Traits In Monkeyflowers: Stigma Closure And Corolla Carotenoids, Rachel Anne Halperin

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Abstract

The interactions between pollinators and flowers have long been a driving force for the evolution of many physical floral traits. Traits such as flower shape, size, color, and smell are just some of these traits that evolve because of these interactions. This evolution does not only occur in the more obvious morphological floral traits, however, but also in more subtle traits like touch sensitive stigma closure. In hundreds of Lamiales species, the bilobed stigma, the organ that receives pollen from pollinators, closes rapidly upon touch. Theory and experiments show that this novel dynamic reproductive trait increases pollen export and …

The Effects Of Beaver Dam Anaolgs On Linked Aquatic-Terrestrial Communities In Western Headwater Streams, Michelle Elyse Fillion, Benjamin P. Colman, Rachel L. Malison

Graduate Student Theses, Dissertations, & Professional Papers

In response to stream degradation resulting from the near eradication of American Beavers (Castor canadensis), managers of freshwater systems have turned to using beaver dam analogs (BDAs) as one means of restoring waterways from stream and riparian degradation. Though BDAs have been shown to restore physical traits of riparian areas, their influence on macroinvertebrates and linked aquatic-terrestrial systems is not well understood. To examine how BDAs influence aquatic habitats, macroinvertebrate communities, and riparian insectivores, we compared unrestored reference stream segments to BDA-restored segments with 7-14 BDAs in three western Montana headwater streams. We collected physical stream measurements and quantitative samples …

Structural And Functional Analysis Of Glun2a-Selective Negative Allosteric Modulators, James Scott Lotti

Graduate Student Theses, Dissertations, & Professional Papers

NMDA-type ionotropic glutamate receptors are widely expressed throughout the central nervous system and are critically involved in many healthy neuronal processes. Dysregulation of NMDA receptor activity underlies many disease pathologies, several of which benefit from treatment with antagonists, such as the FDA-approved channel blockers ketamine, memantine, and adamantine. NMDA receptors are composed of two glycine-binding GluN1 subunits and two glutamate-binding GluN2A-D subunits. The GluN2A-D subunits display distinct regional and developmental expression patterns, enabling region- or cell type-specific targeting of NMDA receptors through subunit-selective pharmacological intervention. There are several classes of subunit-selective negative allosteric NMDA receptor modulators, but the mechanisms of …

Wildfire-Specific Fine Particulate Matter Exposure Impacts On Influenza Across The Western United States, Ava Shulin Orr

Graduate Student Theses, Dissertations, & Professional Papers

Background: In recent years, air pollution, particularly fine particulate matter (PM2.5) originating from wildfire smoke, has surged despite declining anthropogenic emissions. This trend has led to concerning adverse health effects across many different morbidity and mortality outcomes. Still, many gaps remain in understanding of how wildfire-specific smoke impacts our health, including how to isolate the contribution of wildfire-originating PM2.5 within the total ambient or background PM2.5, as well as how and when delayed wildfire smoke exposure will impact certain disease outcomes, and relevant to this dissertation, particularly for communicable respiratory infections, such as influenza.

Purpose: The purpose of this research …

Cultivating Access: The Benefits And Challenges Of Using Community Land Trusts To Preserve Farmland And Support Farmers., Meghan Daly

Graduate Student Theses, Dissertations, & Professional Papers

Agricultural land protected by community land trusts (CLTs) is more likely to remain in active production due to the CLT’s ability to enforce land use practices and select tenants committed to farming. While land tenure approaches vary among CLTs, protected agricultural lands typically utilize long-term leases with affordable rents (Ela and Rosenberg, 2020). Such leasing arrangements enable farmers to access land at prices unaffected by escalating land values (Schwartz et al., 2013). The CLT model not only safeguards farmland but also promotes active agricultural production, thereby ensuring local food supply and providing economic opportunities for farmers.

Despite the promising potential …

Understanding Cellular Dynamics: Investigating A Yeast-Two Hybrid Protein-Protein Interaction, Riok3:Cse1l; Also By Investigating Trogocytosis Of Cd4+ T Cells From Rhog-/- Mice, Brittnee N. Crane

Graduate Student Theses, Dissertations, & Professional Papers

Rift Valley fever virus (RVFV) is a negative-sense virus that was first described in 1930 when it was isolated from sheep during an outbreak. In the last 25 years there has been a spread in the geographical range into the Middle East. The most susceptible animals are cattle, goats, sheep, and camels. The most overt symptom of livestock infection is that infected pregnant animals experience spontaneous abortion. Humans are susceptible as well and symptoms range from mild febrile illness to liver necrosis, blindness, hemorrhagic fever, and death. An important player in the cellular innate response to RVFV infections is the …

Unlocking The West: A Critique Of Previous Statutory Attempts And A Proposed Statutory Solution To Allow Access To Corner-Locked Public Land, Sawyer J. Connelly

Graduate Student Theses, Dissertations, & Professional Papers

Across the American West, 9.52 million acres of federal and state public lands are inaccessible to the public. The legality of accessing much of those public lands through corner-crossing is unclear in the law because, in the infinitesimal space where four corners of land meet in a checkerboard pattern, there is ambiguity; neither private landowners nor the public can assert an exclusive right or absolute control without infringing upon the rights of the other. This paper discusses the origins of landlocked public land, common law doctrines that inform legal actors in this space, and analyzes federal statute and state legislative …

A Closer Look At Denali’S Alpine Wildlife: Assessing The Influences Of Climate And Vegetation Changes On Species In Alaska, Jennifer Lynn Wall

Graduate Student Theses, Dissertations, & Professional Papers

Climate change is amplified in polar regions and could have considerable consequences for biodiversity. Arctic and boreal regions, in particular, have warmed more than double the global average and are experiencing increasing precipitation, thawing permafrost, shrinking snow seasons, and increasing shrub- and tree-line encroachment. These changes are suspected to influence key alpine biodiversity, including species such as collared pikas (Ochotona collaris), hoary marmots (Marmota caligata), and Arctic ground squirrels (Urocitellus parryii). But, we have limited understanding of whether this is true and, if so, which factors drive distributional shifts in response to climate change. For this dissertation, I collected data …

Ambient Air Pollution, Hypertensive Disorders Of Pregnancy, And Geomasking In Montana, Elizabeth Rae Susanne Williams

Graduate Student Theses, Dissertations, & Professional Papers

Background: Air pollution is the world’s largest single environmental health risk. Particulate matter air pollution with aerodynamic diameter ≤ 2.5 μm (PM2.5) poses significant health hazards and has been increasing in some parts of the United States in recent decades due to increased wildfire activity. Prenatal exposure to PM2.5 may increase risk of hypertensive disorders of pregnancy (HDPs), though this has not been evaluated in a rural, wildfire-prone context. To develop recommendations to mitigate harmful health effects of PM2.5, more research is needed to understand the precise timing and dose of PM2.5 that is harmful to human health. Such research …
