Effectiveness Of Lure In Capturing Northern Bog Lemmings On Trail Cameras, Keely Benson

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Fens and bogs are unique wetlands that support a diversity of small mammals and many other rare species. One such species is the Northern Bog Lemming (Synaptomys borealis). This species is being considered for listing under the Endangered Species Act, so determining their presence is helpful for management. Northern bog lemmings are difficult to trap and when they are caught, experience high mortality rates. Since they are hard to capture and study, it is difficult to determine presence/absence of this species for management purposes. This study used a non-invasive, trail camera method for detecting northern bog lemmings in Finley …

Longevity In Snowshoe Hares, Katrina L. Theisen, Alexander V. Kumar, L. Scott Mills

Undergraduate Theses, Professional Papers, and Capstone Artifacts

For small mammals subject to predation, individual longevity, or lifespan, is typically unknown. Snowshoe hares (Lepus americanus) are used as the focal species of this study to examine the assumption that small prey species do not typically live past one or two years of age. To test this assumption, we analyzed a 20-year capture-mark-recapture database to first index the lifespan of hares. We analyzed this database to determine which factors increased the odds of longevity in hares. Body condition and capture location were significant in increasing the odds of a hare being long lived, whereas sex of the …

Group Development In Natural Resource Collaboration In The Crown Of The Continent: Forming, Storming, Norming & Performing, Meghan Rene Neville

Graduate Student Portfolios, Professional Papers, and Capstone Projects

This portfolio brings together three experiences of natural resource collaborative groups each in a different stage of development. Researcher, Bruce Tuckman, theorized that collaborative groups go through different stages in order to grow, face new challenges, tackle problems, deliver results, and become an effective team (1965). These stages of development are called Forming, Storming, Norming, and Performing. The application of Bruce Tuckman’s model can help both collaborative organizers and outsiders appreciate the complex dynamics of collaborative groups. The overarching goal for my portfolio is to provide new ways to examine natural resource collaborative groups, so that there is a better …

The Kite And The String: Why Philosophy Needs More Storytellers, Mason James Voehl

Graduate Student Theses, Dissertations, & Professional Papers

This thesis seeks to explore the relationship between philosophy and storytelling as grounded in their shared task of instructing readers in how to live a rich and moral life. Using a combination of narratives and the philosophical theories of Martha Nussbaum, Edward Mooney, and Iris Murdoch, I claim that philosophy and storytelling ought to be natural allies rather than territorial enemies as each reveals and attends to separate but equally important aspects of the good life in community with others. I then extend this claim into the context of environmental philosophy, using the work of writer Jason Mark as an …

3d Printing Of The Proximal Right Femur: It’S Implications In The Field Of Forensic Anthropology And Bioarchaeology, Myriah Adonia Jo Allen

3D scanning and Printing have become useful in many scientific fields over the last few years, and Physical Anthropology/ Archaeology is not an exception. With skeletal collections decreasing all over the globe and the question of preservation on the rise, it has become necessary to look towards different methods in which one can obtain important information. 3D scanning has become useful over the last few decades and therefore it is important to establish where this new technology can be of use. This paper will bring 3D scanning and printing into question and determine whether this technology should be used in …

An Assessment Of Fecal Water Contamination In The Absaroka-Beartooth Wilderness, Daniel Paul Pendergraph 5024527

Graduate Student Theses, Dissertations, & Professional Papers

Wilderness water sources are often defined as pristine or high quality due to the lack of point source pollution. Non-point source pollution from recreation to water resources can be extensive and is well-studied in protected areas globally. Bacterial contamination, specifically fecal bacteria, poses a significant threat to human health because of the risk for outbreaks of illness and disease. Water sources in designated Wilderness areas are particularly vulnerable to fecal water contamination due to high volume of backpackers and lack of backcountry waste facilities. To estimate the occurrence of fecal water contamination in Wilderness water resources, an exploratory analysis was …

Avoiding Adverse Effects: New Ideas In Drug Discovery For Targeting Pparγ, Trey M. Patton

Graduate Student Theses, Dissertations, & Professional Papers

Peroxisome proliferator-activated receptor gamma (PPARγ) has been a drug target to treat type 2 diabetes for the last 20 years when rosiglitazone and pioglitazone were approved by the FDA in 1999. While effective at increasing insulin sensitivity, these drugs cause serious adverse effects due to their full agonist characteristics. For that reason, drug discovery efforts have attempted to reduce or prevent the amount of agonist character of new PPARγ targeting ligands. Unfortunately, there have been no new FDA approved drugs for the receptor. There is a need for new ideas to produce better quality pharmaceuticals that lessen the impact of …

Multinucleated Giant Cell Formation And Phenotype, Kevin Lewis Trout

Graduate Student Theses, Dissertations, & Professional Papers

Multinucleated giant cells (MGC) are homotypic macrophage syncytia associated with granulomas. Despite their correlation with pathology, MGC functional contributions to inflammation are relatively unknown. The objective of this work was to gain an understanding of MGC phenotype. First, techniques were developed to better enable the study of these cells in vitro. Second, inorganic particles known to cause inflammation were observed to cause MGC formation in the lungs. Finally, the particle that resulted in the highest macrophage fusion was used together with the in vitro system to compare MGC and macrophage phenotype in response to stimulation. The results contribute to fundamental …

Dna Analysis On Ceramic Cooking Vessels, Britney J. Radford

Graduate Student Theses, Dissertations, & Professional Papers

Ceramic vessels are a durable material found in abundance throughout the archaeological record. Organic residue analysis has been used to study ceramic vessels utilizing lipid analysis and protein analysis. Lipids and proteins analysis provide limited information at the genus level, leaving out valuable information that species-specific results can tell us such as unique genetic and environmental information. Lipids and proteins analysis provide limited information at the genus and taxonomic levels leading to issues of misclassification of species. If only certain animals or plants of a genus are being used, then unique genetic and environmental information found only at the species …

Unconfined Wilderness Experiences: What Is Important To Feeling Unconfined While Visiting The Selway-Bitterroot Wilderness?, Jonathan Daniel Dorman

Graduate Student Theses, Dissertations, & Professional Papers

The principal aim of this study was to increase our understanding of an “unconfined type of recreation”. This management objective is mandated by the Wilderness Act of 1964 and has received little empirical focus within visitor experience research. A 20-item survey research scale was developed and found to be valid and reliable when considering what is important to feeling unconfined in the Selway-Bitterroot Wilderness of Idaho and Montana. The scale included four components or factors that were labeled, “Free Choice”, “Untethering from Responsibility”, “Making Own Plans”, and “Exploring”. In addition, the Perceived Freedom in Leisure Scale was administered and showed …

Reconnecting Indigenous Knowledge To The Sunlight Basin: Integrating Traditional Ecological Knowledge And Archaeology, Liz Dolinar

Graduate Student Theses, Dissertations, & Professional Papers

Traditional ecological knowledge (TEK) specific to plants has been developed over long-term connections to the environment, diligent observations, and practical experience by Indigenous communities. The traditional ecological knowledge of Indigenous peoples is a vital source for the contextualization and further understanding of past human environmental relationships in the Sunlight Basin of northwestern Wyoming. The Eastern Shoshone people, among many other groups, traditionally occupied the Sunlight Basin of northwestern Wyoming, a region of the Greater Yellowstone Ecosystem. There is a growing necessity for collaboration with Indigenous populations within archaeological and anthropological research. The aim of this project is to develop a …

Protecting Natural Resources On Agricultural Lands: Producers' Perspectives On The Conservation Stewardship Program In Montana, Mary Ellis

Graduate Student Theses, Dissertations, & Professional Papers

Industrial agricultural production contributes to some of the most significant environmental problems in the United States today. Scientists have identified agricultural production as a primary cause for the decline of native species, soil degradation, and water pollution in the U.S. In response to this crisis, grassroot organizations crafted, and got Congress to pass, the Conservation Stewardship Program (CSP), a federal program aimed to incentivize producers to increase on-farm conservation practices. CSP is designed to serve as a space for producers to gain access to financial and technical support, test out new practices, and provide a platform to discuss best practices …

Shaping The Tools Of Battle : Sexual Selection, Contest Dynamics, And Weapon Divergence In The Asian Rhinoceros Beetle Trypoxylus Dichotomus, Jillian F. Del Sol

Graduate Student Theses, Dissertations, & Professional Papers

Exaggerated weapons of sexual selection often diverge more rapidly and dramatically than other body parts, suggesting that relevant agents of selection may be discernible in contemporary populations. I examined the ecology, reproductive behavior, and strength of sexual selection on horn length in five recently diverged beetle populations that differ in relative horn size. I show that mating system ecology differs between these locations and corresponds with the local strength of contemporary selection on horn length. Comparisons of ecological conditions and selection strength across populations offer a critical first step towards meaningfully linking mating system dynamics, selection patterns, and diversity in …

Characterization Of Novel Cyp26b1-Inhibitor, Dx314, For The Treatment Of Keratinization Disorders, Joachim Gwenn-Stephan Veit

Graduate Student Theses, Dissertations, & Professional Papers

Our skin, particularly the barrier provided by the epidermis, functions as our primary protection from the harsh environment. It protects us from dangerous pathogens, allergens, ultraviolet radiation, and mechanical injury, as well as playing a major role in fluid and thermal regulation. Disruption of skin functions can lead to life-threatening consequences due to increased risk of infection, trans-epidermal water loss, and allergen sensitization. Many common skin disorders often result in a disrupted skin barrier placing patients at risk of complications.

Retinoic acid (RA) is a major component of the vitamin A pathway, which critically controls multiple skin functions including cell …

Development Of An Open-Source, Custom Environmental Data Logger For Spatially Scalable Data Collection, Tim Anderson

Graduate Student Theses, Dissertations, & Professional Papers

Characterizing the processes that lead to differences in ecosystem productivity and watershed hydrology across complex terrain remains a challenge. This difficulty can be partially attributed to the cost of installing networks of proprietary data loggers that monitor differences in the biophysical factors contributing to vegetation growth or hydrological processes. Studies that aim to compare concurrent time-series data sets across multiple locations must therefore balance the high cost of these data logger systems with the need for spatial resolution in their data. Here, we present the design, implementation, and case study for an open-source “Pinecone” data logger system, released under the …

Adaptive Potential To Camouflage Mismatch: Plastic And Evolutionary Responses To A Climate Change Stressor, Marketa Zimova

Graduate Student Theses, Dissertations, & Professional Papers

Animals that occupy temperate and polar regions have specialized traits that help them survive in harsh, highly seasonal environments. One particularly important adaptation is seasonal coat colour (SCC) moulting. Over 20 species of birds and mammals distributed across the northern hemisphere undergo complete, biannual colour change from brown in the summer to completely white in the winter. But as climate change decreases duration of snow cover, seasonally winter white species (including the snowshoe hare Lepus americanus, Arctic fox Vulpes lagopus and willow ptarmigan Lagopus lagopus) become highly contrasted against dark snowless backgrounds. The negative consequences of camouflage mismatch and adaptive …

The Genetic Mechanisms Underlying Pigmentation And Their Evolutionary Importance In Birds, Nicholas David Sly

Graduate Student Theses, Dissertations, & Professional Papers

Integumentary pigmentation is a phenotype of fundamental importance to animals, with major impacts on survival and fitness. Thus, understanding the mechanisms underlying pigmentation can help illuminate general principles about how adaptive variation is generated and maintained in populations. Here, I present a dissertation that is aimed at understanding the developmental, regulatory, and genetic mechanisms that underlie variation in avian plumage color, and their evolutionary importance.

In my first chapter, I addressed how the modular organization of plumage traits may impact their evolution. The production of color in developing feathers is a modular process, with several mechanisms combining to produce the …

Assessing The Robustness Of Time-To-Event Abundance Estimation, Kenneth E. Loonam

Graduate Student Theses, Dissertations, & Professional Papers

Abundance estimates can inform management policies and are used to address a variety of wildlife research questions, but reliable estimates of abundance can be difficult and expensive to obtain. For low-density, difficult to detect species, such as cougars (Puma concolor), the costs and intensive field effort required to estimate abundance can make working at broad spatial and temporal scales impractical. Remote cameras have proven effective in detecting these species, but the widely applied methods of estimating abundance from remote cameras rely on some portion of the population being marked or uniquely identifiable, limiting their utility to populations with naturally occurring …

Crow Indian Tribe V. United States, Hallee Kansman

Public Land & Resources Law Review

The protection status of the Greater Yellowstone grizzly bear continues to elicit debate and find its way into the courtroom. In Crow Indian Tribe v. United States, for the second time in the last decade, a court held the Service’s attempt to delist the Yellowstone Grizzly arbitrary and capricious. Specifically, the court found the Service’s evaluation of remnant populations, recalibration, and genetic health deficient. This case demonstrates the importance in and the resilient motivation behind preserving grizzly bear populations and genetics. As the practice of delisting a species under the Endangered Species Act continues, this case will provide important …

Still-In-Flux: Reinterpreting Montana's Rights-Of-Minors Provision, Rebecca Stursberg

Montana Law Review

This note explores how this provision, referred to interchangeably as Article II, Section 15 and the rights-of-minors provision throughout, has developed since its adoption. Part II of this note discusses the sources of the provision, including key United States Supreme Court precedent on juvenile rights in the years immediately before the Convention, and the evolution of the provision through several stages of the 1972 Montana Constitutional Convention. Part III examines the structure and substance of Article II, Section 15 by dividing the provision into three subparts and illustrating how each sub-part functions through relevant Montana Supreme Court decisions. Part IV …
