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, …

Parent And Guardian: An Interpretative Phenomenological Analysis Of Sexual And Gender Minority-Affirming Caregivers, Kelly Marie Davis

Graduate Student Theses, Dissertations, & Professional Papers

Studies consistently demonstrate that sexual and gender minority (SGM) youth experience mental health disparities when compared to their heterosexual, cisgender peers due to identity-based stressors (Meyer, 2003). Given the startling rates at which this population experiences mental health challenges, there has been an ever-increasing focus on prevention and intervention efforts to promote resilience and well-being among SGM youth. Over the past several decades, scholars studying resilience in development have identified the importance of effective caregiving in buffering against adversity. However, little is known about the specific practices that caregivers of SGM youth might employ to strengthen their relationships and to …

Effects Of Timber Harvest On Understory Vegetation Succession: A Time Series Study, Reese A. Poindexter, Trevor Weeks, Chad Bishop, Akasha Faist

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Timber harvest, as a necessary and common global practice, can significantly affect the ecosystems being harvested through opening the canopy, disturbing the understory, and resetting successional trajectories. This study examined how timber harvest influenced understory plant functional group dominance, understory species richness, and understory species dominance along a 40-year, or older, harvest timeline across two forest types (mesic and xeric) in Northwestern Montana, U.S.A. In our two forest types, vegetation sampling was completed at 208 sites with 1,040 quadrats across six timber-harvest timelines. Harvest timelines varied from the most recent at 1-5 years post-harvest to over 40 years as the …

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 …

Peoples Of India: The Use Of Craniometric Data To Distinguish A Separate Ancestral Group, Stephanie A. Craig

Graduate Student Theses, Dissertations, & Professional Papers

The Peoples of India come from an area with a long history of migrations into and out of the area. This area is considered the second most diverse genetically outside of Africa. Many would group these people as Asian due to the country’s location. However, when studies are done on the skeletal remains from this area, the remains tend to give results of mixed or indeterminate ancestry unless the analyst is familiar with identifying Peoples of India. This study aims to determine the Peoples of India as a separate ancestral group separated from Asians, Europeans, and Africans. To do this, …

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 …

Regulation Of Er To Golgi Transport By Alg-2 And Peflin In Response To Calcium Signaling, And A Review Of Relevant Genetically-Encoded Fluorescent Tools, Danette M. Kowal Seiler

Graduate Student Theses, Dissertations, & Professional Papers

The endoplasmic reticulum performs multiple functions in the eurkaryotic cell: biomolecule synthesis, protein folding, cargo sorting and secretion, and helping to maintain cellular calcium homeostasis. Though much has been discovered about these processes and the myriad proteins, enzymes, transcription factors, ions and other factors that play their own parts, much is still left to learn. To facilitate continued study of ER-to-Golgi transport, an array of genetically-encoded fluorescent tools are available to researchers. The featured review in Chapter 1 details the history of these tools and highlights some of the newest, which also incorporate information from the fields of synthetic chemistry …

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. …

Age, Loneliness, And Culture: Fostering Intergenerational Connections, Amelia Hawes, Clara Totman, Holly Mahon, Maddy Snow, Zachery Craig

Undergraduate Theses, Professional Papers, and Capstone Artifacts

When considering global health issues, physical illnesses are often regarded as the most pressing threats. However, a growing body of research indicates that loneliness poses significant risk to global wellbeing. A worldwide study conducted by Gallup and Meta found that one in four people report feeling at least some loneliness on a day-to-day basis. Loneliness is not only pervasive, but is thought to actively harm holistic wellbeing. United States Surgeon General Vivek H. Murthy has argued that chronic loneliness is “as detrimental to our physical health as smoking fifteen cigarettes per day.” While no age group is immune, the elderly …

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 …

Interannual Growth-Climate Relationships Of Western Larch After Wildfire In The Northwest, Junior Burks

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Montane and mixed-conifer forests in the northwestern United States are burning at rates greater than any time in recent decades, due to the combined impacts of global warming and historical and contemporary land use and land management. Western larch (Larix occidentalis) is a tree of high regional significance, exhibiting a variety of traits that make it resistant and resilient to fire. Because seedlings are more sensitive to environmental stressors than adults, the impacts of climate change are expected to be detectable first in juvenile trees. Recent research shows that the natural regeneration of western larch after wildfires has …

Carbon Allocation To Growth And Storage In Pinus Ponderosa During And Following Experimental Carbohydrate Limitation, Ella M. Keefer

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Understanding how plants allocate carbohydrates to growth and storage in the face of drought and other stresses that reduce carbohydrate availability is crucial to predict ecosystem responses to future stress events. Growth is critical for resource acquisition while storage of carbohydrates is critical as a safeguard during stress. Despite this, how plants allocate carbohydrates to growth and to non-structural carbohydrate (NSC) storage under drought and carbohydrate limitation is poorly understood. We examined how carbohydrate limitation, with and without drought, affects carbon allocation to growth versus stored NSCs. We found that under carbon limitation and depletion of stored NSC, NSC storage …

The Impact Of Treatment Dosage On Cognitive-Linguistic Outcomes Of Patients With Aphasia: An Investigation Of Three Service Delivery Models, Adele J. Derendinger

Graduate Student Theses, Dissertations, & Professional Papers

This study addresses the gap in literature by directly comparing the effectiveness of Intensive Comprehensive Aphasia Programs (ICAPs) and modified ICAPs (mICAPs) to usual care service delivery models for people with aphasia. Through a prospective study design, cognitive-linguistic function change scores across different service delivery models were examined. The findings reveal significant within-group improvements in cognitive-linguistic function for participants in ICAPs, with some improvement seen in mICAPs and usual care conditions. Intensive models demonstrated greater improvement compared to non-intensive usual care models, particularly evident in the Western Aphasia Battery – Revised and the Boston Naming Test – Second Edition. …

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 …

Perspectives On Using Pharmacogenomics To Guide Tobacco Cessation: Survey Results From An American Indian Community, Daniela Mariana Wall

Graduate Student Theses, Dissertations, & Professional Papers

Pharmacogenomics research has predominantly focused on populations of European ancestry, limiting the application for diverse populations such as American Indian and Alaska Native (AIAN) communities. Our community-centric study aims to understand perspectives of utilizing pharmacogenomics to guide tobacco cessation in an AIAN community using a survey with qualitative and quantitative components. We assessed participant (n=273) tobacco usage and cessation history, pharmacogenomics knowledge, and perceptions of utilizing pharmacogenomics in the context of tobacco cessation. We found that the majority of participants (92%) were aware of risks associated with tobacco usage and believe it to be a problem within their community (76%). …

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 …

Temporal And Spatial Connectivity And The Impacts Of Hydropower In The Magdalena River Basin, Colombia, Serena Lynn Butler

Graduate Student Theses, Dissertations, & Professional Papers

Tropical regions hold untapped hydropower potential, but dam construction often adversely impacts multiple dimensions of connectivity in river systems, rigorous evaluation of which is often lacking. This study investigates temporal and spatial dimensions of longitudinal and lateral connectivity in the Magdalena River Basin, Colombia, a region with ongoing and planned hydropower projects. Limited in-situ monitoring data is a common challenge in tropical rivers. To address this, we utilized satellite imagery from Landsat (via Google Earth Engine) and Surface Water and Ocean Topography (SWOT) data. We examined alterations in the flow regime over time and relative to dam construction. We also …
