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 …

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 …

Digitizing The Corporeal: The Affect Of Mediatized Elements In Theatrical Performance, Kurtis Layne Hassinger

Graduate Student Theses, Dissertations, & Professional Papers

This paper explores the affect of digital media in live performance. The research is generated from work with integrated digital media in Carol Ann Duffy's 2015 adaptation of Everyman as well as Samuel Beckett's radio play Cascando. Through experimentation and implementation of motion tracking digital elements and actor-manipulated sonic and visual digital media achieved with MIDI and OSC mapping, I explore the embodiment of performances by actors when their various characters are represented on the physical as well as the digital stage simultaneously.

The research interrogates digital media in storytelling when actors can manipulate imagery and language in real time …

This geochemical study will use chemical signatures to tease out the daily activities that were performed by the inhabitants of Housepit 54. A …

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 …

Computer Modelling Of Neurotoxicity And Auditory Processing Disorder In The Rat After Chronic Lead Intoxication, Silas Brewer Smith

Graduate Student Theses, Dissertations, & Professional Papers

Objective: Past research documents the ototoxicity of inorganic lead (Pb), which in children may include associated auditory processing and learning disabilities. The present investigation aims to explore in computer modelled rats, as a laboratory animal model, the persistent effects of Pb-contaminated drinking water on measures. i.e., wave latency and amplitude, of auditory brainstem function and specifically the response to a known evoked-potential assessment of Backward Masking (BM) as a marker of Auditory Processing Disorder (APD). BM refers to the disruption of an animal's response to a stimulus when succeeded by a later stimulus temporally.

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 …

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 …

Water For Fish And Farms: An Examination Of Instream Flow Programs In Montana Using Spatially-Explicit Water Rights Data, Anna Leigh Crockett

Graduate Student Theses, Dissertations, & Professional Papers

The state-level institutions governing water use in the western United States have increasingly come under pressure and scrutiny related to their inability to navigate water use conflicts in recent decades. Rapid population growth and shifting public values towards leaving water instream for recreational and environmental purposes pose challenges to Montana water supplies which are predominantly allocated for irrigated agriculture. Additionally, while water scarcity and unpredictable availability are not new dilemmas in Montana, the rate at which climate change is driving shifts in the distribution, timing, and availability of water supplies is unprecedented. Current water policies may not be nimble enough …

Golden Eagle Resource Selection And Environmental Drivers Of Reproduction In The Northern Range Of Yellowstone National Park, David Brown Haines

Graduate Student Theses, Dissertations, & Professional Papers

In the United States (US), National Parks are considered the “crown jewels” of protected lands. However, the importance of National Parks to wildlife populations and the species that inhabit them is not often quantified, thus, requiring a better understanding of National Parks as a conservation tool. Golden eagles (Aquila chrysaetos) are a North American species of conservation concern and territories in the northern range of Yellowstone National Park (YNP) are relatively dense. However, average reproductive rates over the past ten years (2011-2020) have been low (productivity = 0.34, nest success = 28%). The contrast of high density and …

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 …

Tribal Consultation Policy And Practice:A Case Study Of The Confederated Salish And Kootenai Tribes And Nmisuletkʷ (The Middle Fork Of The Clark Fork River) As A Tribal Trust Resource, Jennifer J. Harrington

Graduate Student Theses, Dissertations, & Professional Papers

Formal, government-to-government Consultation between sovereign nations is a process of continuous relationship-building, a partnership and an agreement made with all points-of-view included in the process, with results that have the fingerprint of all nations involved evident. The Federal Government is obligated to work with Federally-recognized Tribes as sovereign nations in matters that have or will impact each Nation’s people and places (reservations, treaty-protected areas)—a process legally known as Consultation. The Environmental Protection Agency (EPA), as a federal agency, must uphold the Federal Trust responsibility which includes the act of Consulting with Federally-recognized Tribes on matters involving human health and the …

Understanding Native American Hemp Production, Cynthia Marie Steckdaub Coleman

Graduate Student Theses, Dissertations, & Professional Papers

In this thesis, I take an in-depth look at Native American hemp production through the lens of three hemp projects. My research sits within the history of colonization and dispossession. I look at two tribal hemp projects and one individual Native American hemp farm and describe how each project reaches for tribal sovereignty through hemp production. I look at how hemp fits into tribal worldviews, cultures, and the relationship tribal farmers have with hemp. Focusing on key elements of relationship, like respect, reciprocity, and responsibility, I examine how hemp production can be incorporated into Indigenous communities. Beyond relationships with the …

Perceived Threat And Left-Wing Authoritarianism: The Effect Of Framing On Persuasive Messages, James Donald Mcfarland

Graduate Student Theses, Dissertations, & Professional Papers

Past research reveals a strong connection between feeling threatened and Right-Wing Authoritarianism (RWA). This relationship is considered to be an integral part of authoritarianism and the nature of its presence in the left-leaning populace is still being fully explored. This study examined the relationship between perceived threat and Left-Wing Authoritarianism (LWA) through the framing of persuasive messages. Participants (n = 256) were recruited through Amazon’s Mechanical Turk (MTurk) and given a list of reward- or threat-framed statements concerning the possible ramifications of voting in future elections and then asked to rate the quality and persuasiveness of the respective statements. …

2890-Fish On Fluoxetine: Before During And After Behavioral Analysis, Susan Marie Greene

Graduate Student Theses, Dissertations, & Professional Papers

Chemical concentrations of antidepressants have increased over the years steadily building in surface waters globally. These drugs have had various impacts on the animals tested, such as impacts on movement, motivation, and reproduction. In order to further investigate the effects of the antidepressant fluoxetine, male Betta splendens were exposed to the drug. These fish are naturally aggressive for reproduction purposes and have easily observable aggressive responses to other male fish. These characteristics make them a good model for studying Fluoxetine’s impact on reproduction, motivation, and movement. Males in this study were primed with either a female or empty chamber prior …

Tending To The Tapestry: An Ecofeminist Interpretation Of Women Farmer-Artists' Stories, Aubrey Pongluelert

Graduate Student Theses, Dissertations, & Professional Papers

There is a disconnect in Western academia, between classroom conversations concerning the impact of environmental degradation on rural communities, and engagement with those communities whom we are discussing. Those working in environmental studies are confronted with the question of how to effectively communicate the concerns addressed by the field in ways which are accessible to, and engage broader audiences. Creative languages such as the visual arts, storytelling, and music are invaluable tools in this task because they offer accessible and culturally relevant means of conveying ideas, perspectives, and experiences. This project examines the ways in which these creative languages contribute …

Flowers From The Devil: An American Opiate Crisis, The Criminalization Of Marijuana, And The Triumph Of The Prohibition State, 1840-1940, Clinton David Lawson

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation focuses on historic changes in public perception of narcotic use and abuse from the mid-nineteenth century to the mid-twentieth. From the 1840s to the outbreak of Civil War, politicians, physicians, the general public, and state and federal government remained largely ambivalent on the topic of drug use. Opium, morphine, and cannabis were legal, widely available in American pharmacies, and touted as essential medicines. Within the Bohemian community, artists and writers experimented with the recreational use of cannabis and their accounts of that style of consumption filled the pages of Harper’s, The New Yorker, and a host of other …

Synchrony: An Aspect Of The Abilities Of Steppe Horse Archers In Eurasian Warfare (525 Bce – 1350 Ce), Chris Hanson

Graduate Student Theses, Dissertations, & Professional Papers

Animals moving in unison as a group are quite intriguing to observe. Horses can run across terrain and change directions without jostling each other. They appear to move as if they know how to avoid crashing into others and run fluidly through their environment. This ability to maneuver without hindering herd is called synchrony and also extends to other animals including fish in schools and birds in flocks. Humans, on the other hand, need to create orderly formations in battle to move without interfering with adjacent warriors. For example, the Romans, Greeks, Persians, Chinese, and Byzantines trained their infantry and …

Diet-Breadth Analysis In The American Southwest: Metabarcoding Method With Coprolites, Paige Nicole Plattner

Graduate Student Theses, Dissertations, & Professional Papers

Molecular analysis of coprolites is proposed as new means of studying bio-archaeological remains that aids in the ability to capture diet breadth from past populations. This research utilizes the targeted PCR method, known as metabarcoding, to study dietary elements preserved in the coprolites from three greater Southwest sites. The Illumina MiSeq technology was used to sequence the samples after multiple rounds of targeted PCR using two primers (16s and 12s) proven successful for taxonomic identification with animal DNA and one primer specific to plant DNA (Rias et al 2011).

The sequencing data was then run through two different bioinformatics pipelines …

In a time when students are more disconnected from the outdoors than ever. The use of trail cameras, based on these experiences, has the potential to reconnect students to the …

School Counselor Self-Advocacy And Trait Emotional Intelligence As Predictors Of Professional Quality Of Life In School Counselors, Kindle Dawn Lewis

Graduate Student Theses, Dissertations, & Professional Papers

School counselors are integral to the holistic success of students and are needed now more than ever as high rates of youth mental health issues, traumatic events at schools and global crises have become part of every school year. Unfortunately, as with most helping professions, many school counselors are struggling with maintaining a healthy professional quality of life due to chronic stress work environments. School counselors who have higher levels of compassion fatigue (burnout and secondary traumatic stress) and lower levels of compassion satisfaction are more likely to have decreased quality of care for students, decreased self-efficacy, decreased overall wellbeing …

Epigenetic Alterations In Response To Multi-Walled Carbon Nanotubes And Dha Diet Modification, Elizabeth Michelle Cole

Graduate Student Theses, Dissertations, & Professional Papers

Multi-walled carbon nanotubes (MWCNTs) are a class of engineered nanomaterials that pose airborne exposure risks to human health. Immense variations in physical properties such as size and shape complicate understanding the underlying mechanisms and consequences of MWCNT exposures. There are concerns that exposures can lead to chronic pulmonary inflammation and fibrosis diseases, as is the case with other more known ultra-fine respirable materials with similar physical properties, such as crystalline silica and asbestos. Pro-inflammatory diseases can be regulated by epigenetic changes, which can be influenced by environment, including diet. Docosahexaenoic acid (DHA) is an omega-3 fatty acid that may promote …

Developing a Decision-Making Framework for Assisted Migration: Applying this to the

American Pika and White Bark Pine

This paper analyzes a novel conservation strategy: assisted migration (AM). AM is the practice of moving a highly vulnerable (i.e., endangered) species impacted by climate change and other exacerbating factors (e.g., land use), out of its historic range to a recipient site. Ideally, this site would be one where the species would have migrated, were there no barriers to dispersal or anthropogenic stressors. The paper is concerned with the readiness of the conservation community—particularly …
