Evolution Of A Nitrogen-Fixing Endosymbiont And Integration With Its Diatom Host, Heidi Elizabeth Abresch

Graduate Student Theses, Dissertations, & Professional Papers

Endosymbiosis, where one cell lives inside of a different cell, is ubiquitous in nature and has enormous impacts on the ecology and evolution of both the host and the endosymbiont [1, 2]. These relationships exist along a continuum ranging from facultative—where both partners are able to live independently—to completely obligate—where partners can only survive in the presence of the other. The most famous examples being the chloroplast and mitochondrion [3]. After hundreds of millions or even billions of years of coevolution, highly-integrated endosymbionts are coordinated with the host on the genetic, metabolic, and cellular levels, but we do not understand …

Communicating Wildfire Risk In Real Time: An Idea Model Analysis Of Watch Duty Alerts, Audrey E. Miller-Greene

Graduate Student Theses, Dissertations, & Professional Papers

Traditional wildfire public information systems often rely on fragmented data provided through multiple government agencies and platforms. Historically, community members have been required to identify and piece together information necessary for preparation, evacuation, and decision-making during wildfire events. Watch Duty, a 501(c)(3), works to address this gap by compiling fragmented wildfire information for the public. The platform has undergone rapid growth and increased public reliance, providing a rationale for this research project. As Watch Duty expands its capabilities, its messages should be evaluated against established risk and crisis communication best practices. This study evaluates alerts released by Watch Duty during …

Developing Identity After Goodbye: Social Identity Theory And How Adolescent Survivors Navigate Suicide Loss, Elizabeth Susan Lawton

Graduate Student Theses, Dissertations, & Professional Papers

Adolescents who lose a loved one to suicide, known as suicide-loss survivors, face a disruption to identity development, a life stage defined by identity formation (Adler et al., 2018) and group belonging (Pittman & Richmond, 2008). Suicide bereavement is complicated not only by grief but also by stigma, which can fracture social ties and undermine self-concept. Social identity theory (SIT) provides a framework for examining how young adults, now ages 18 to 30, reconstruct their social identities after experiencing suicide loss in adolescence. Research in other stigmatized contexts shows that adopting positive in-group identities can buffer against stigma and protect …

Á’Po’Taki Iiyika’Kimaa Work/Try Hard For Such A Time As This, Misamsai’Piaakíí Longtime Charging Woman Kimberly Lynn Paul

Graduate Student Theses, Dissertations, & Professional Papers

This body of work adds to a recent shift in the academic landscape, valuing interdisciplinary research and Indigenous worldview. Predominant is the reversal of extractive research norms within Indigenous populations and the biosystems they steward, instead claiming Piikani (Blackfeet) led community-needs-based research valuing Indigenous data sovereignty, research methodologies, ethics, equity, and Indigenous empowerment. This research proffers requisite historical information providing the ‘why’ context, followed by three of the author’s studies: in toxic dumping, food sovereignty, and Piikani well-being. Under an environmental justice framework, the first study presents a cursory investigation of decades-long illicit toxic waste disposal reports linked to observed …

The Forensic Implications Of Hydrochloric Acid (Hcl) Exposure On Dna Preservation In Human Teeth, Shaelyn Lee Zimmerman

Graduate Student Theses, Dissertations, & Professional Papers

Identity is a human right, and forensic anthropological methods are often aimed at returning identity to decedents. Three main pathways are used for the identification of human remains: fingerprints, dental records, and DNA analysis. Identification efforts may be hindered when perpetrators attempt to obscure the victim’s identity. In cases where corrosive substances, such as hydrochloric acid (HCl) are used, dental comparison and fingerprinting often fail and genetic analysis becomes the best chance of achieving personal identification.

Previous studies have shown teeth are an excellent source of DNA. Large, multi-rooted teeth, such as molars, are often preferred because they contain the …

Between Care And Protection: Constraints On Political Authority In Kamala Harris's 2024 Presidential Campaign, Marissa Barbara Pax

Graduate Student Theses, Dissertations, & Professional Papers

Competing expectations about strength, care, and protection shape how presidential leadership and authority are constructed in contemporary U.S. politics, particularly for members of marginalized communities. This thesis examines Kamala Harris’s 2024 presidential campaign as a case study to explore how candidates negotiate competing understandings of political authority through appeals to Lakoff’s (2002, 2008) Strict Father Morality and the Nurturant Parent Morality. An analysis of her campaign reveals that Harris repeatedly appeals to both moral frameworks, constructing authority through empathy, mutual responsibility, and care while also emphasizing threat identification, protection, discipline, and moral strength. Although Harris successfully mobilizes the rhetorical resources …

Unmuted: An Augmentative And Alternative Communication User’S Experience In Accessing And Engaging In Mental Health Care, Kanbi Faith Knippling

Graduate Student Theses, Dissertations, & Professional Papers

Communication accessibility is a critical yet underexamined factor influencing access to and engagement in mental health care for individuals who use augmentative and alternative communication (AAC). Existing literature suggests that AAC users experience significant barriers to obtaining communication-accessible mental health services, including limited provider preparation, communication-related assumptions, and broader structural inequities. Despite growing recognition of these concerns, little research has explored how AAC users experience and navigate mental health counseling or how communication accessibility shapes participation in care.

This single-case study explored communication accessibility within the context of an adult AAC users' experiences accessing and engaging in mental health counseling. …

Growing Agroecology: Two Case Studies From The U.S. Student Farm Movement, Amelia B. Armstrong

Graduate Student Theses, Dissertations, & Professional Papers

Scholars and activists identify agroecology as a crucial science, practice, and movement to move towards more just, equitable, and sustainable agriculture and food systems. Yet, the exploitative industrial food system, that deepens inequalities like food insecurity (Clapp et al., 2025), reduces farmer autonomy (Rotz, 2015), and contributes to increased carbon emissions (Lin et al., 2011) and biodiversity decline (Rotz, 2015), still dominates. Understanding and mobilizing the different spaces that teach agroecology, then, is a crucial step in challenging the dominant industrial food system. Agroecology education in university settings is an important domain to investigate as potential contributors to this movement, …

A Psychogeography Of The Lower Colorado River Basin, Arren L. Kimbel-Sannit

Graduate Student Theses, Dissertations, & Professional Papers

Dried-up canals. Superheated strip malls. Proliferating data centers. Infinite appetite for growth despite its apparent circumstances. Arizona may well be the state of the American future. This multi-genre series of essays from Arren Kimbel-Sannit offers a personal, political-economic and ecological critique of growth and accumulation in Arizona — from the perspective of someone who grew up in its suburban expanses, reported on its politics, and long sought to clarify his relationship with home.

Race, Sexual Danger, And The Moral Logic Of Punishment In The Registry Era, Edith Meade

Graduate Student Theses, Dissertations, & Professional Papers

Sex offender registries represent one of the most expansive and punitive criminal justice interventions in modern American history, yet public support for these policies remainsunderi nvestigated. Scholarly debate has questioned whether punitive attitudes toward sexual offenders reflect principled moral judgments, racial threat perceptions, or both. This study addresses that question by examining how offender race, offender age, offense severity, victim age, and offender-victim relationship shape public attitudes toward sexual offenders in the contemporary registry era. Drawing on theories of racialized sexual threat, group position, and retributive impulses, the study uses a nationally representative conjoint survey experiment administered through YouGov (N …

Graduate Student Theses, Dissertations, & Professional Papers

An aging grieving artist decides to write a memoir as part of a self-healing process, using samples of song lyrics from his extensive collection of original Americana songs as narrative prompts.  Steeped in wanderlust, aspiration, paradox and dysfunction, his is a tale of vexing sub-clinical troubles rooted in the mire of developmental and religious trauma.

Illusions Of Fairness And Sacrifice, Brady Schwertfeger

Graduate Student Theses, Dissertations, & Professional Papers

The American West is a shifting landscape. An incongruous expanse of isolation and urbanity, wilderness and extraction, wealth and welfare, clear water and fire. Fifteen years ago, I moved to my mother’s ancestral homeland of Montana, and have been here ever since. Before that, I was born and raised in Texas, both the West and the South (and often something else entirely), depending on who you ask. My experiences in this region have shaped me indelibly, and have inspired this collection of essays built around culture, politics, and justice in the West. “Pinedale, Wyoming” considers the musician as itinerant wanderer …

The Experience Of A Single Parent Participating In Child-Parent Relationship Therapy: An Instrumental Single-Case Study, Matthew Nicholas Schramm

Graduate Student Theses, Dissertations, & Professional Papers

Traditional family structures in the United States have shifted significantly, with single-parent households facing systemic barriers that increase parental stress and strain the parent-child relationship. As this bond is critical for healthy child development, accessible mental health support is essential for these families (Parache et al., 2023).

Child Parent Relationship Therapy (CPRT), a ten-week evidence-based program, strengthens this bond by training caregivers to use play as a therapeutic tool (Landreth & Bratton, 2020). This instrumental single case study (Stake, 1995) examined one single-parent's experience of CPRT delivered in a condensed four-week telehealth format, addressing the limited representation of single-parent households …

Spatiotemporal Dynamics Of Mountain Front Recharge Flow Paths And Their Contribution To Alluvial Aquifer Water Supply, Mikaela Bollag-Miller

Graduate Student Theses, Dissertations, & Professional Papers

Mountain Front Recharge (MFR) is a critical recharge source for alluvial basin aquifers throughout the Intermountain West, yet the spatial and temporal dynamics of distinct recharge pathways remain poorly constrained. This study investigates the seasonal and spatial dynamics of MFR pathways and evaluates their impact on the Missoula Aquifer, a sole-source alluvial aquifer in western Montana, USA. MFR includes both surface-water inflows from mountain areas and Mountain Block Recharge (MBR), the groundwater contribution to the basin aquifer. A valley-scale water balance was employed to estimate first-order contributions and temporal fluctuations of MBR flow paths. A three-layer steady-state MODFLOW groundwater model …

Estimating Sediment Properties Using A New Source Level Function For Wind-Driven Underwater Sound Derived From Long-Term Archival Data, S Bruce Martin, Martin Siderius

Electrical and Computer Engineering Faculty Publications and Presentations

Wind-driven breaking waves generate the background sound throughout the ocean. An accurate source level for wind-driven breaking waves is needed for estimating the ambient sound levels needed for sound exposure modeling, environmental assessments, and assessing the detection performance of sonars. Previous models applied a constant roll-off of sound levels at -16 dB/decade at all wind speeds, and these models' source levels were flat at frequencies below ∼1000 Hz due to a lack of measurements. Here, we analyzed 16 long-term archival datasets with limited anthropogenic sound sources to estimate the wind-driven source level down to 100 Hz. We estimated the site-specific …

Beyond The Indian Act: Restoring Traditional Government In Kahnawà:Ke Through Haudenosaunee Law, Brandon Montour

Osgoode Hall Law Journal

The Kanien’kehá:ka of Kahnawà:ke have been subjected to the Indian Act since 1889. Its forceful imposition has eroded ancestral governance systems and severed vital threads of cultural and social life. In 2024, the Mohawk Council of Kahnawà:ke—the Indian Act band council—declared its intent to restore traditional governance and unilaterally end the Indian Act’s reach within the territory. This work is presently underway in Kahnawà:ke. Against this backdrop, and in light of generations of collective experiences of trauma brought on by the forces of settler-colonialism, this article considers what role Haudenosaunee law can play in bringing community members together to build …

Faculty, Staff and Students Publications

Improving self-management skills for adolescents and emerging adults (AEA) with chronic health conditions is critical for successful transition to adult-based care. Peer-mentoring has been effective in improving the self-management skills of AEA. However, the components of training a successful young adult peer mentors (YAPM), especially interpersonal aspects of the role, such as communication skills and navigating mentee ambivalence are not well understood. This descriptive study created and pilot-tested a training curriculum for YAPM as part of a larger study to build self-management skills in the context of healthcare transition from pediatric to adult care. Five YAPM completed the training curriculum. …

Application Of Coastal Change Management Areas (Ccmas) For Coastal Adaptation To Climate Change Impacts In Sw England, Josie-Alice Kirby

School of Biological and Marine Sciences Theses

Coastal Change Management Areas (CCMAs) were introduced into the English planning system in 2012 to enable anticipatory management of long-term coastal change. However, their implementation has been limited and inconsistent, reflecting uncertainty in how future shoreline change should be defined and translated into statutory planning boundaries. This thesis addresses the gap between national coastal adaptation policy and the scientific evidence required to support its practical application.The research combines policy analysis, geomorphological classification and probabilistic modelling to develop a structured framework for delineating areas of future coastal change. Chapter 2 evaluates the national implementation of CCMAs and demonstrates substantial variability in …

Coping With Climate Change: The Role Of Plasticity Within And Across Generations, Caitlin Mcandry

School of Biological and Marine Sciences Theses

Climate change is leading to increased mean temperatures and more frequent and severe temperature anomalies, threatening organisms globally. Phenotypic plasticity, the ability of a given genotype to express different phenotypes in different environments, may offer a mechanism that allows organisms to temporarily persist in a rapidly changing environment, ultimately buying time for genetically based adaptations to evolve. Plasticity has been demonstrated both within and across generations, in response to different environmental stressors. However, our understanding of the interactive effects of plastic responses across levels of biological organisation, and over temporal scales from hours to generations, is still limited. Additionally, we …

Taking Snaps Of Plant Life Conditions: Designing A New Crop Autonomous Micro-Environmental Recording Array, Sohail Saeed

School of Biological and Marine Sciences Theses

Accurate measurement of plant microclimate is essential for understanding how local environmental conditions influence plant growth and response. In many experimental setups, environmental monitoring is performed using a single measurement point, which may fail to capture spatial variability across a plant array. This thesis presents the design, validation, and deployment of a compact distributed sensing system, referred to as C.A.M.E.R.A. (Crop Autonomous Micro-Environment Recording Array), developed to measure plant microclimate conditions at multiple locations simultaneously.The system integrates air temperature and relative humidity sensing using the SHT85, multi-point soil temperature measurement using DS18B20 probes, and relative light monitoring using the SEN0390 …

Investigating The Determinants Of Fight Dynamics In The Minotaur Beetle Typhaeus Typhoeus, Amy Bromley

School of Biological and Marine Sciences Theses

It is widely accepted that the main determinants of contest outcome are resource value, residency status, and resource holding potential, with each of these playing an important role in determining contest behaviour. Examples of resource holding potential are morphological traits such as body size and weaponry. Animals that possess weaponry can exhibit different morphotypes, such as size difference in horns, which can lead to differences in contest behaviour, with larger morphotypes engaging in head-to-head combat, while smaller morphotypes can avoid combat altogether. One such species that possess weapons in the form of horns and engages in physical combat, is the …

Plastic Pollution: Investigating Environmental Pathways And Critically Evaluating Interventions, Florence Parker-Jurd

School of Biological and Marine Sciences Theses

Plastics are lightweight, versatile, and durable materials used in the manufacture of a wide range of products. Innovation in the early 1950’s facilitated a dramatic reduction in production costs with the potential to mass produce inexpensive convenience items intended for single use applications. As a consequence, plastic production has grown exponentially over the last 75 years, and a throw away culture of single use has become deeply engrained in modern society. Plastic production exceeds 450 million tonne/yr, substantially exceeding our capacity to manage associated waste resulting in pollution accumulating in every compartment of the natural environment. While plastic pollution has …

Influence Of Ecological Transitions On The Evolution Of Circadian And Light Detection Genes In Squamates, Isobel Sleep

School of Biological and Marine Sciences Theses

Circadian rhythms are self-sustaining, endogenous processes that align behaviour and physiology with daily environmental cycles. Rhythms are regulated by conserved genes forming transcriptional feedback loops and are entrained by environmental cues (e.g., light). Circadian systems are well studied in model organisms, their molecular evolution in squamates (lizards and snakes) remains less understood. Squamates represent the most species-rich reptile group with extensive ecological and sensory diversity, exhibiting multiple independent transitions across ecological niches, including repeated shifts into low-light environments (e.g., nocturnality, fossoriality), making them ideal for examining circadian and light-associated gene evolution. This study investigates how ecological transitions have influenced the …
