Linear Programming Analysis And Diet Breadth Modeling At Bridge River, British Columbia, Sean Patrick Boyd

Graduate Student Theses, Dissertations, & Professional Papers

Studies in diet breadth modeling and patch choice have been and continue to be a hot topic of interest among practitioners of human behavioral ecology and the set of data available at Bridge River can certainly add to these debates and discussions that have been dominating anthropology in the past few decades. The faunal assemblage of Housepit 54’s 17 anthropogenic floors have provided researchers with a plethora of data that clearly indicates periods of resource depletion and partial to full site abandonment. Using Linear Programming and Diet Breadth Modelling I analyze the most represented species in the record and establish …

Facilitating Aquatic Invasive Species Management Using Satellite Remote Sensing And Machine Learning Frameworks, Sean C. Carter

Graduate Student Theses, Dissertations, & Professional Papers

The urgent decision-making needs of invasive species managers can be better met by the integration of biodiversity big data with large-domain models and environmental data products in the form of new workflows and tools that facilitate data utilization across platforms. Timely risk assessments allow for the spatial prioritization of monitoring that could streamline invasive species management paradigms and invasive species’ ability to prevent irreversible damage, such that decision makers can focus surveillance and intervention efforts where they are likely to be most effective under budgetary and resource constraints. I present a workflow that generates rapid spatial risk assessments on aquatic …

He, She, They, Other: An Examination Of Gender Associations With The Chatelaine In The Anglo-Saxon Culture, Dane A. Williams

Graduate Student Theses, Dissertations, & Professional Papers

The purpose of this paper is to study the chatelaine as a marker of gender attribution and overall usage within the Anglo-Saxon culture. Chatelaines are artifacts used to suspend multiple items to be employed for such purposes as grooming, tools, or keys and have been used widely from the Roman occupation of England during which it was used by all genders, to the Ninth Century when it was primarily used by women. As such, it is asserted that a single artifact should not to be solely relied upon to assign a gender identity to a burial, that these should be …

Conservation In Ecuador's Sangay-Podocarpus Connectivity Corridor: A Study Of Coproductive Capacities, Gabriel Isaac Oppler

Graduate Student Theses, Dissertations, & Professional Papers

Connectivity conservation, a growing topic across science, policy, and management, is considered an important supplement to protected areas. A diversity of ecological corridors is emerging to restore fragmented landscapes, preserve intact habitats, protect biodiversity, and improve resilience to climate change. Despite increasing expertise and resources for planning corridors, many initiatives face challenges mobilizing science and governance to implement corridors on the ground. In many cases, biophysical science is supplemented with social science to better understand the human elements of connectivity. Similarly, collaboration and partnership are heralded as essential for effective governance of corridors. However, less is known about how these …

An Integrative Investigation Of The Synechococcus A/B Clade During Adaptive Radiation At The Upper Thermal Limit Of Phototrophy, Christopher L. Pierpont

Graduate Student Theses, Dissertations, & Professional Papers

Thermophilic microorganisms have been scientifically observed since the early nineteenth century and have spurred many questions about the limits of life and the capacity of organisms to survive extreme conditions. Decades of research on thermophile proteins and genomes have yielded several proposed correlates of temperature that may contribute to adaptation of bacteria and archaea to high temperature. However, many of the generalizations reported are drawn from analyses of deeply divergent taxa or from individual case studies in isolation from mesophilic relatives. Members of the Synechococcus A/B (SynAB) group are the only cyanobacteria with members able to grow above 65 °C …

The Effect Of Attentional Manipulation On Cough Reflex Sensitivity In Patients With Cough Hypersensitivity Syndrome, Jane Elizabeth Reynolds

Graduate Student Theses, Dissertations, & Professional Papers

The cough reflex is complex and requires integration of sensorimotor information from the central and peripheral nervous system. Cough motor output can be volitionally modified even when a strong urge-to-cough (UTC) is felt which reinforces the idea of cortical involvement in cough and opens the door to consider how manipulating attention or changing cognitive load may impact cough reflex sensitivity. Two prior studies have shown healthy individuals have reduced cough reflex sensitivity to inhaled tussigenic stimulants when completing a distracting task, presumably due to influence from increased cognitive load. In this prospective case series study, 13 patients with cough hypersensitivity …

Development Of Nanodisc Affinity Capillary Electrophoresis To Study The Interaction Of Giα Protein With Cell Membranes, Bethany R. Emeigh

Graduate Student Theses, Dissertations, & Professional Papers

Guanine nucleotide-binding proteins, or G-proteins, are crucial to cell signaling by acting as molecular switches through interactions with membrane-bound receptors. G-proteins have become of greater interest due to the possibility of novel drug targets. The G-protein alpha subunit, Gα, binds GTP before localizing to the membrane to interact with other G-protein subunits and G-protein-coupled receptors (GPCRs). Gi lacks a hydrophobic region to promote localization to the membrane, but a co-translational lipidation of the N-terminal residue stabilizes this interaction.

Protein interactions with biological membranes are challenging to study due to the complex structure of membranes and the often-limited quantities of the …

Mitigating The Damaging Effects Of Covid-19 Isolation In The Elderly, Hailey Powell, Addie Slanger, Mazana Boerboom, Brenna Spurling, Maria Goheen

Undergraduate Theses, Professional Papers, and Capstone Artifacts

In an effort to both analyze how COVID-19 has impacted traditionally isolated communities and prevent loneliness, we have created a pen-pal program between UM students and senior adults. We have implemented a pilot pen-pal program to create lasting social bonds without exposing seniors to COVID-19. The program is currently running through the Davidson Honors College “Intro to Honors” course, with plans to leave the program self-sustaining in future semesters. To pair partners, we distributed interest surveys and matched relevant interests. To inform people of how loneliness affects seniors, we created a brochure that highlights our research, with plans to distribute …

Getting To Know You: Relationship Formation Across Development In Octodon Degus, Amber Lynn Thatcher

Graduate Student Theses, Dissertations, & Professional Papers

Social relationships are a necessary part of group formation and cohesion across many animal species and can increase the health and fitness of the individuals involved. These benefits are seen across the lifespan, although the exact advantages and functions differ across developmental stages. Our current understanding of how relationships are formed and maintained is incomplete. Previous findings suggest that a measure of stability may be a useful method for understanding how relationships are formed and how this process may differ across development. The goal of this dissertation is to investigate the variability of social interactions over time and how it …

Preliminary Study In More Effective Utilization Of 87sr/86sr Analysis In The Field Of Forensic Anthropology, Samantha Powers

Graduate Student Theses, Dissertations, & Professional Papers

Isotopic analyses are gaining attention in the field of anthropology. The current utilization of strontium isotopes primarily focuses on residence and migration patterns of past populations extracting data from tooth enamel to indicate early-life residence This study aims to identify a skeletal feature to be set as a field standard in strontium analysis of modern remains when seeking end-of-life residence, the impact of diagenesis on modern remains, and to test the accuracy of the petrous as an alternative to tooth enamel.

The results of this research were unable to suggest such a standard but gathered helpful data to be used …

Re-Storying Grant Creek: A Case Study Of Relational Dynamics On A Degraded Montana Stream, Seamus Rucci Land

Graduate Student Theses, Dissertations, & Professional Papers

The UN Decade on Ecosystem Restoration began in 2021, and after a history of contentious ethical debates, ecological restoration is increasingly portrayed as a viable framework for combating environmental degradation and supporting more healthy and stable social-ecological systems. The proposed ecological restoration of Grant Creek, a degraded stream near Missoula, Montana, offers an opportunity to connect a restoration site to the broader, rapidly growing field of restoration practice. It also allows the opportunity to forward the ‘relational turn’ proposed by many in the sustainability sciences as an ontological and methodological means to move beyond positivist portrayals of social-ecological systems, which …

Other Orchards, Sam B. Robison

Graduate Student Theses, Dissertations, & Professional Papers

Other Orchards is comprised of poems each suspect in their own way of those boundaries that might separate humans from nature, rural from urban, worker from scholar, or human from beast. Using the figure of the orchard, a kind of “false forest,” this collection studies the ways we map ourselves onto our work and the way work might inform an understanding of the self. Ultimately, these are poems that emerge from the seams of things—the shoulder of highway strewn with dead antelope, the feral apple tree lost to the woods, the farmer lost in their work, slowing becoming less and …

Conserving And Sharing Freshwater In The West, Kelsea Harris-Capuano

Graduate Student Theses, Dissertations, & Professional Papers

There are infinite stories to be told about water in the West. As an essential and finite resource, countries, states, tribal nations and neighbors must figure out how to manage this shared resource, whether for ecosystem sustainability, agricultural, household, or recreational use.

As a result of seasonal lake level fluctuations controlled by the dam, erosion over the years has …

Rancher Perspectives On Livelihood Diversification Options In Montana's Blackfoot River Watershed, Sara N. Schmidt

Graduate Student Theses, Dissertations, & Professional Papers

The Blackfoot River watershed in Western Montana, like many rural landscapes across the Intermountain West, has faced a suite of economic, demographic, and social change over the last 40 years. Cattle ranching specifically, a principal land use in the Blackfoot watershed, has faced increasing socioeconomic challenges due to global competition, falling cattle prices, amenity migration, and climate change. Ranch livelihood diversification presents an opportunity to bolster the profitability of ranches in the watershed, while also supporting the well-being of rural communities and conserving the intact, ecologically-significant rangelands upon which ranching depends. The Blackfoot Challenge (BC) is a nonprofit community-based conservation …

The Mountain Home: Spatial And Optimal Foraging Assessments Of Hunter- Gatherer Mountain Landscape Use In The Beartooth Mountains, Montana, Scott William Dersam

Graduate Student Theses, Dissertations, & Professional Papers

Patterns of cultural mountain adaptations are recorded throughout the Western Cordillera of North America. They demonstrate prolonged and complex uses of these ecosystems over the Holocene. What behaviors or circumstances in the Early Holocene transitioned mountains from inhospitable to reliable territory? This research addresses this question in the Beartooth Mountains of the Greater Yellowstone Ecosystem (GYE).

Foraging behaviors dictate hunter-gatherer mobility and habitation patterning. These behaviors are reflected in the spatial arrangement of archaeological activity areas and lithic tools in mountainous ecosystems. Energy-demanding ecosystems, require foraging behaviors and habitation strategies that conserve energy. I assert that to understand the emergence …

Body Temperature And Reproductive Effort In A Long-Lived Tropical Songbird, Holly R. Jackson

Graduate Student Theses, Dissertations, & Professional Papers

Heat production relative to dissipation rates have constrained reproductive effort and reduced fitness in short-lived, temperate birds. To determine whether heat constrains reproductive effort in long-lived taxa with low reproductive effort, we experimentally clipped plumage from tropical Gray-throated babblers (Stachyris nigriceps) to increase heat dissipation rates. Contrary to findings in short-lived species, we found no strong evidence of heat dissipation constraints on reproductive effort in our mid-elevation study. Clipped adults did not increase feeding rates compared to controls, but clipped females did spend more time incubating and brooding eggs and young. Increased time in the nest may reduce increased heat …

Epistemoligical Uncertainty And Political Ideology: Exploring The Relationship Between Temporal Threats And Ideology, James Donald Mcfarland

Graduate Student Theses, Dissertations, & Professional Papers

Research in motivation suggests that individuals are highly attuned to perceived risk and danger and tend to form groups (physical and ideological) on the basis of the threats they collectively share with like-minded others. These initial stages of threat detection and evaluation are often found to occur through subtle environmental cues. This study examined the relationship between feelings of uneasiness and political ideology through the framing of temporal cues (e.g., past- vs. future-tense). Participants (n = 181) were recruited through Amazon’s Mechanical Turk (MTurk) and were randomly assigned a short vignette about a relatable life experience (e.g., purchasing a car). …

Bridging The Gap: Where Indigenous Knowledge And Western Science Come Together To Shape Environmental Stewardship, Bowman Leigh

Graduate Student Theses, Dissertations, & Professional Papers

In the era of climate change, humans are grappling with how to ensure that natural resources exist into the future. For millennia, Indigenous people have actively managed the environment, drawing upon deep connections to the land passed down through generations. The Western worldview, on the other hand, sees humans as separate from nature — an attitude that has led to many of the environmental crises we see today.

This portfolio examines places and programs where Western science and Indigenous knowledge (IK) or traditional ecological knowledge (TEK) come together to shape environmental stewardship. Western science and IK/TEK are inherently different ways …

Distal Sibling Grief: Exploring Emotional Affect And Salience Of Listener Behaviors In Stories Of Sibling Death, Margaret C. Brock

Graduate Student Theses, Dissertations, & Professional Papers

Communicated Narrative Sense-Making (CNSM) theory is used as a theoretical framework to understand the storytelling surrounding a sibling’s death years after the loss. Analysis of 174 narratives from individuals whose siblings died five or more years ago revealed that a neutral tone, rather than the use of positive or negative affect, was predominant in this retrospective storytelling. When affect was present, it was more likely to be negative than positive. However, positive affect was associated with an individual’s satisfaction with life when it was present. The neutrality and frequency of retrospective storytelling among distally bereaved siblings in this study may …

Voices Of The Often Unheard: The Environmental Impacts Of Catastrophic Wildfire Events On Individuals With Developmental Disabilities, Mary Madison Mckenzie

Graduate Student Theses, Dissertations, & Professional Papers

The Thomas Fire for a time was the largest wildfire in California history, burning 281,893 acres and destroying 1,063 structures. Within three years, the August Complex Fire, at 1,032,649 acres, almost quadrupled that record. Climate related disasters such as these have impelled social science researchers to heed calls for a paradigm shift in understanding the risks climate change poses to the social world, in particular, disaster risks for vulnerable groups. Existing research tends to focus on disasters such as hurricanes, featuring risks for vulnerable populations by race, class, and/or individuals with disabilities in general, but not for individuals with developmental …

Catch My Drift? Perceptions And Experiences Of Pesticide Contamination Of Organic Crops In Montana, Sarah Rodgers

Graduate Student Theses, Dissertations, & Professional Papers

Pesticide drift and inadvertent contamination pose particular risks to organic production. Some organic producers have lost their crops, certification, and/or organic markets because of contamination events. Through this thesis research, I explain the perceptions and experiences that certified organic farmers in Montana have about drift and inadvertent pesticide contamination. I conducted semi-structured interviews with eleven certified organic farmers from various regions of Montana. Along with one-on-one interviews with organic farmers, interviews with industry and regulatory officials were conducted to better understand the policies and procedures that control what happens when drift occurs at the state level. Industry and regulatory official …

Genetic Rescue Of Isolated Cutthroat Trout, Donovan Alexander Bell

Graduate Student Theses, Dissertations, & Professional Papers

Anthropogenic habitat destruction has isolated innumerable populations that now face increased extinction risk due to demographic and genetic factors. Although often the best strategy, restoring connectivity can be challenging or even harmful. Such is the case for westslope cutthroat trout (Oncorhynchus clarkii lewisi; WCT) in the Missouri River basin, which are limited to completely isolated populations. Nonnative species threaten WCT in connected watersheds and barrier removal could be detrimental. My dissertation examines trade-offs and strategies for the management of isolated WCT. I first examined how nonnative trout species and climate change influence the distribution of WCT using a multispecies, dynamic …

Alternative Splicing Regulates The Innate Immune Response To Viral Infection, Luke A. White

Graduate Student Theses, Dissertations, & Professional Papers

Rift Valley fever virus (RVFV) is a mosquito-borne RNA virus that infects humans and livestock in sub-Saharan Africa and the Arabian peninsula, causing disease ranging from a mild flu-like illness to liver damage, blindness, hemorrhagic fever, death, and, especially in livestock animals, high rates of abortive pregnancies. There is no approved vaccine for RVFV, and as a disease with a high rate of spread that causes severe illness, it is listed as a Category A pathogen by the USA CDC. A better understanding of RVFV’s molecular virology will be instrumental to combating RVFV as climate change causes its mosquito host …
