"Blackfeet Belong To The Mountains": Blackfeet Relationships With The Glacier National Park Landscape And Institution, David R. Craig

Graduate Student Theses, Dissertations, & Professional Papers

National Parks are home to many landscapes of great significance to Native American peoples. The eastern half of Glacier National Park is considered a homeland by the Blackfeet people, and has historically been very important to their material, cultural, and spiritual well-being. This relationship, like those of many other Native peoples, has been severely disrupted by the establishment and presence of the national park, resulting in prolonged conflict between tribes and parks. Blackfeet relationships with this cultural landscape require interaction and engagement in order to realize the full extent of its benefits. Often, these practices serve distinct material needs, however, …

Around The World And Back: A Discovery In India, Charlie L. Gaare

Graduate Student Theses, Dissertations, & Professional Papers

The impetus for my journey was the desire to learn more about another culture, and pursue the idea of the old cliché: be the change I wanted to see in the world. This journey fulfilled the requirements of the project in multiple ways. It was a major risk to travel to another country with a language barrier on my own. The amount of work it took to prepare for the trip and face the challenges of the experience itself was very labor intensive. I had to do this because I needed to see that I could make a difference. I …

Lessons To Learn From All Out Invasion: Life History Of Brown Trout (Salmo Trutta) In A Patagonian River, Sarah Louise O'Neal

Graduate Student Theses, Dissertations, & Professional Papers

Brown trout (Salmo trutta) are widely introduced throughout Patagonia, though their distribution and impact in the region remain poorly documented. Life history flexibility, and particularly partial migration play a major role in the ability of this species to adapt to Patagonian rivers. Consequently, this study explored habitat, distribution and life history of a partially migratory population of brown trout in the Rio Grande in Tierra del Fuego, Argentina. It described what is known of the history of the invasion. Physical, chemical, and biological habitat data were collected for comparison between sites supporting resident fish with those supporting anadromous fish. Additionally, …

Seasonal Nutrient Dynamics In A Small-Scale Constructed Wetland Treating Primary Effluent With Applications Of Effluent Reuse In Biomass Production, Paul Thomas Miller

Graduate Student Theses, Dissertations, & Professional Papers

Constructed wetlands have been investigated for use in the treatment of municipal wastewater. Species of nitrogen and phosphorus are the nutrients of focus and biochemical oxygen demand (BOD), total suspended solids (TSS) and fecal coliform are the pollutants. Prior work has focused on design concepts, plant effects on nutrient and pollutant treatment, and annualized treatment performance characteristics. This work builds upon published design concepts and wetland plant community and its function and investigates seasonal treatment performance and the kinetics of treatment performance for certain nutrients and pollutants during each season. Previous engineering based work has broadly suggested that first order …

Sex-Specific Investment In Incubation And The Reproductive Biology Of Two Tropical Antbird Species, Brian A. Schwartz

Graduate Student Theses, Dissertations, & Professional Papers

Paternal care has been neglected in behavioral studies because it is rare among most animals. Birds express wide variation in male care across a broad life-history gradient, but such variation among species remains poorly explored. At the same time, contributions of male assistance with incubation have been largely overlooked with the assumption that incubation is a time of low parental energy expenditure. We compared male versus female biparental incubation effort between two tropical antbird species in the northern Andes of Venezuela. We found that males and females apportion reproductive effort differently between these two species, but that male contributions of …

Siamese Fighting Fish (Betta Splendens) Show Self-Control For Access To A Mirror, Christopher Matthew Collins

Graduate Student Theses, Dissertations, & Professional Papers

Self control is defined as choosing a larger, delayed reinforcer over a smaller, more immediate reinforcer with the opposite defined as impulsivity. In general, results from self-control research involving avian and non-primate mammalian subjects have shown a strong to moderate impulsive choice bias whereas studies using adult humans and non-human primates have shown a strong self-control bias. While the non-human self-control literature is rich with studies using select avian and mammalian species, there is very little self-control literature on the choice behaviors of fish or social reward. The present experiment assessed preference in male Betta splendens using an immediate/2 sec …

Kings And Courtesans: A Study Of The Pictorial Representation Of French Royal Mistresses, Shandy April Lemperle

Graduate Student Theses, Dissertations, & Professional Papers

This thesis explores the development in the pictorial representation of four important French royal mistresses. It looks at works depicting Agnès Sorel, mistress to Charles VII; Diane de Poitiers, mistress to Henri II; Gabrielle d’Estrées, mistress to Henri IV; and Madame de Pompadour, mistress to Louis XV. By placing the portrayals of these women within a historical context, it becomes apparent that there are links between the strength of the crown and the depictions of the mistresses. This thesis traces the development of the imagery associated with these women and demonstrates that as the crown became more and more powerful, …

Wildlife Decomposition In West Central Montana: A Preliminary Study Conducted To Provide Field Investigation Material And Training For Wildlife Officers, F. Carleen Gonder

Graduate Student Theses, Dissertations, & Professional Papers

An issue with many poaching investigations is the discovery of carcasses in advanced stages of decomposition with little information to indicate time of death (TOD). To address TOD issues of carcasses found in a state of decomposition, and to provide training materials and field tools for investigating officers, this project was initiated to identify decomposition stages and to monitor decomposition rates for those stages in the west central area of Montana. A total of 15 carcasses were placed in electrified exclosures during various times of the year which provided seasonal variation and include: a pair of gray wolves (8 total) …

Design, Synthesis And Biological Evaluation Of A Family Of Excitatory Amino Acid Transporter 3 (Eaat3) Preferring Inhibitors, Terri Lynn Mavencamp

Graduate Student Theses, Dissertations, & Professional Papers

This work describes the synthesis and initial characterization of the biological activity of a family of EAAT3 preferring inhibitors, L-β-benzyl aspartate (L-β-BA) and L-β-BA derivatives. L-β-BA and derivatives were initially synthesized in an approximate 2:1 ratio of diasteromers (threo:erythro), using base promoted enolate addition. Kinetic analysis of 3H-D-aspartate uptake into C17.2 cells expressing the hEAATs demonstrated that L-threo-β-BA is the more potent diastereomer (Ki values of 9 µM for EAAT1, 10.0 µM for EAAT2 and 0.8 µM for EAAT3), acts competitively, and exhibits a 10-fold preference for EAAT3 compared to EAAT1 and EAAT2. Electrophysiological recordings of EAAT-mediated currents in Xenopus …

Causes And Consequences Of The Postfire Increase In Deer Mouse (Peromyscus Maniculatus) Abundance, Rafal Pawel Zwolak

Graduate Student Theses, Dissertations, & Professional Papers

Wildfire triggers an increase in deer mouse (Peromyscus maniculatus) abundance. Here, I describe this phenomenon, investigate its causes, and explore the consequences of the postfire increase in mice for conifer recruitment in burned forest. I documented a shift in small mammal communities away from more specialized species such as red-backed voles (Myodes gapperi) and shrews (Sorex spp.) and towards greater abundance of generalist deer mice after a wildfire in montane forest. I conducted a meta-analysis of published studies on the abundance of small mammals in disturbed versus undisturbed forests and established that the pattern of increased deer mouse abundance holds …

Changes In Osteoarthritis Of The Elbow And Shoulder Joints In Women When Trasitioning From Hunting And Gathering To An Agricultural Subsistence, Kirsten Anne Green

Graduate Student Theses, Dissertations, & Professional Papers

Changes in bone morphology have always been a concern of physical anthropologists who are trying to explain a culture's everyday activity. These types of changes, including arthritic and musculoskeletal, are based on subjective observation of the researcher and therefore subject to observer error. I used three samples; the Indian Knoll sample, the Nutwood and Rosedale Mound sample, and a control sample from the Terry collection I was able to employ a scoring method based on Hawkey (1988). This current research uses the scoring method for arthritic changes in women to test for changes in patterns of distribution and/or severity when …

Greater Sage-Grouse Response To Coal-Bed Natural Gas Development And West Nile Virus In The Powder River Basin, Montana And Wyoming, Usa, Brett Lincoln Walker

Graduate Student Theses, Dissertations, & Professional Papers

Understanding how population dynamics respond to landscape-scale disturbance and disease are crucial for effective wildlife management and conservation. Two new potential stressors on greater sage-grouse (Centrocercus urophasianus) populations in the Powder River Basin of Montana and Wyoming are coal-bed natural gas (CBNG) development and West Nile virus (WNv). I first examined how CBNG development, habitat, and other landscape features influenced trends in the abundance of displaying males and the status of sage-grouse leks. Second, I used rates of WNv-induced mortality and seroprevalence from radio-marked birds to estimate rates of WNv infection. Third, I studied the influence of female characteristics, season, …

Mobile Genetic Elements In Coxiella Burnetii: Friends, Foes Or Just Indifferent?, Rahul Raghavan

Graduate Student Theses, Dissertations, & Professional Papers

The genome of the obligate intracellular pathogen Coxiella burnetii contains a large number of mobile genetic elements including two group I introns and an intervening sequence (IVS) that interrupt the 23S rRNA gene; an intein within dnaB (encoding replicative DNA helicase) and a homing endonuclease. The introns are self-splicing ribozymes and able to inhibit ribosome function and retard bacterial growth through internal guide sequence (IGS)-dependent and -independent mechanisms. The introns were found to be highly conserved in all eight genomic groups of C. burnetii, suggesting a role in C. burnetii's biology. It is not clear whether the introns are being …

Oxidative Stress And The Guanosine Nucleotide Triphosphate Pool: Implications For A Biomarker And Mechanism Of Impaired Cell Function, Celeste Maree Bolin

Graduate Student Theses, Dissertations, & Professional Papers

Oxidation of the guanosine (G) moiety, yielding the oxidized lesion 8-hydroxy-2'-deoxyguanosine (oxo82dG), in DNA has become a hallmark biomarker in assessing cellular outcomes induced by oxidative stress. It is well established that the guanosine nucleotide triphosphate pool is also susceptible to oxidative stress and suggested to be more available for oxidation than DNA due to the lack of protective histones and robust repair mechanisms for reducing the levels of all the products of oxidation. The oxidation of guanosine in the nucleotide triphosphate pool, resulting in oxidized guanosine 5'-triphoshate (oxo8GTP), has been overlooked due to the lack of a reliable method. …

The Extravaganza Awaits, Kathryn Lorraine Rodriguez

Graduate Student Theses, Dissertations, & Professional Papers

Abstract The Extravaganza Awaits This paper addresses ideas in my thesis work, consisting of a series of paintings which evolved into installation. My ideas concern notions of spectacle, consumption of information, and self-gratifying selection. I lighten these ideas with humor and treat them with a carnivalesque aesthetic, appropriate to the absurdity that I see characteristic of them. Painting places the issues in a narrative context, but the story remains open- ended to allow the viewer to bring personal associations to the work. I specifically selected images of friends and family unfamiliar to the viewer and a lexicon of personal symbols …

A Simple Gis Approach To Predicting Rare Plant Habitat: North Central Rocky Mountains, United States Forest Service, Region One, Erin Elizabeth Nock

Graduate Student Theses, Dissertations, & Professional Papers

Understanding the potential distribution of rare species is a key component in managing and regulating land-use activities. Predictive modeling of plant distributions rests on the assumption that correlations exist between the presence or absence of a species and selected climate, topographic, substrate, and land-cover variables. Using the DOMAIN algorithm along with Geographic Information Systems (GIS) techniques, a biophysical envelope model was applied to 21 rare plant species listed on the Region One Regional Forester’s Sensitive Species List. Environmental variables, including annual precipitation, mean May temperature, slope, aspect, elevation, geologic material and dominant vegetation type, were used as predictors. Model output …

These twenty teachers were broken into two cohorts, cohort one served as the experimental group and cohort two served as the control group. Students within these classrooms ranging in grades 5 - 12, took two assessments, …

Acute Cellular Uptake Of Abnormal Prion Protein Is Cell Type And Scrapie Strain Independent, Christopher Scott Greil

Graduate Student Theses, Dissertations, & Professional Papers

Transmissible spongiform encephalopathies (TSEs) are fatal neurodegenerative diseases that include Creutzfeldt-Jakob disease, bovine spongiform encephalopathy and sheep scrapie. TSE disease pathology and mechanisms within the central nervous system (CNS) of an infected host largely remains unclear. At the cellular level, the uptake of protease resistant prion protein (PrP-res), which strongly correlates with infectivity and is a valid marker for TSE infection, is one of the earliest events that must occur during TSE infection. Given the difficulty of clearly distinguishing input PrP-res from either PrP-res or protease-sensitive PrP (PrP-sen) made by the cell, the uptake of PrP-res from an infectious inoculum …

Cottonwood Establishment In A Gravel-Bed River, Claudio Ivan Meier

Graduate Student Theses, Dissertations, & Professional Papers

I investigated the processes of establishment of the cottonwood Populus trichocarpa T.&G. along the pristine, 5th order, wandering floodplain of the gravel-bed Flathead River, Montana, USA. The focus of my research was to determine the mechanisms explaining successful recruitment on recently formed, unvegetated bars, covering a range of spatial scales from within-bar (~ 1 to 10 m) to across-reach (~ 1 to 10 km). Results are based on field observations and measurements over three growth seasons (2005 through 2007), as well as outdoor and laboratory experiments.

At the within-bar scale, I used a paired-plot sampling design to compare closely-located sites …

Demography And Ecology Of A Declining Endemic: The Olympic Marmot, Suzanne Cox Griffin

Graduate Student Theses, Dissertations, & Professional Papers

Protected areas serve to conserve species, habitats, and ecological processes. However, biological systems within even large parks are increasingly affected by outside perturbations. The Olympic marmots (Marmota olympus) are ground-dwelling squirrel that inhabit high-elevation meadows almost exclusively within Olympic National Park Despite this protection, anecdotal reports in the 1990's of disappearances from historically occupied locations suggested that the species was in decline. I used demographic monitoring, habitat surveys, and non-invasive genetic sampling to evaluate population status of the species and consider the effects of several possible stressors. Olympic marmots disappeared from ~50% of well-studied colonies, and abandoned burrow complexes were …

Pre- And Post-Copulatory Sexual Selection In The Tortoise Beetle Acromis Sparsa (Coleoptera: Chrysomelidae), Paula Alejandra Trillo

Graduate Student Theses, Dissertations, & Professional Papers

Females in nearly all sexually reproducing taxa mate with multiple males. In these species, male fitness is dependent on traits used during both the pre-copulatory processes influencing mate acquisition, as well as the post-copulatory processes influencing fertilization. However, few studies have simultaneously examined pre- and post-copulatory sexual selection within a particular species, and we therefore have little understanding of how these processes interact to determine male reproductive success.

The objective of my study was to gain a more comprehensive understanding of the evolution of sexually selected traits by examining the interactions between pre- and post-copulatory processes in the tortoise beetle …

Residential Development Patterns In Flathead County, Montana, Louis Anthony Jarvis

Graduate Student Theses, Dissertations, & Professional Papers

Population growth in the Non-Metropolitan West has increased over the last two decades. Many researchers have argued that natural amenity concerns, the quality and diversity of the environment, and the rural nature of the non-metropolitan West are the chief factors influencing individuals’ decisions to settle. This research examines a single high-amenity county in Western Montana, Flathead County, and analyzes the factors affecting land values and the probability of residential development at the parcel level. This research develops spatial variables thought to affect land values in an ArcGIS 9.2 environment and develops a regression model that estimates land values based on …

Conservation And Status Of Markhor (Capra Falconeri) In The Northen Parts Of North West Frontier Province, Pakistan, Sajjad Ali

Graduate Student Theses, Dissertations, & Professional Papers

Pakistan is blessed with a great variety of wild flora and fauna, including a rich diversity of wild Caprinae (sheep and goats) represented by 7 species divided into 12 subspecies. These animals are found in Balochistan and Sindh in the south and the North West Frontier Province (NWFP) and Northern Areas in the north. Markhor is a wild goat which belongs to the family Bovidae and sub family Caprinae. In 1992, it was transferred from Appendix II to Appendix I of the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES). The inclusion of markhor in …

The Rewilding Of New York's North Country: Beavers, Moose, Canines And The Adirondacks, Peter Aagaard

Graduate Student Theses, Dissertations, & Professional Papers

This project examines the restoration histories of beavers (Castor canadensis), moose (Alces alces americana), and wild canines (Canis spp.) within the Adirondack Highlands of northern New York. Devastated by the depredations of nineteenth century woodsmen, the populations of these large mammals rebounded during the twentieth century. Numbering fewer than ten in 1895, the Adirondacks’ remnant beaver population recolonized the region’s lakes, ponds, streams, and rivers over the next twenty-five years, assisted by the presence of prime habitat, a state-enforced moratorium on beaver trapping, and timely reinforcements. Hunters shot the last of the Adirondacks’ moose near Raquette Lake in 1861. Moose …

Spatial Variability In Forest Fuels: Simulation Modeling And Effects On Fire Behavior, Russell Andrew Parsons

Graduate Student Theses, Dissertations, & Professional Papers

Forests in the western United States and elsewhere face a growing crisis arising from global warming, changes in fuel beds and an increasing human population. Fire management policy emphasizes fuel treatments, such as thinning and prescribed burning, to remedy this situation because fuels are the one component of the problem that we can directly affect through management action. At present, however, the tools we have for the evaluation of fuel treatments are inadequate because they do not describe the fuel bed, or effects of modifications to the fuel bed on fire behavior in sufficient detail. The work described here presents …

Role Of Scavenger Receptor Marco In Particle Uptake And Lung Inflammation, Sheetal A. Thakur

Graduate Student Theses, Dissertations, & Professional Papers

Alveolar macrophages (AM) form the first line of defense against chronic inflammation caused by occupational exposure to environmental particulates such as crystalline silica (CSiO2). The chronic inflammatory process triggered by CSiO2 is known to culminate into a fibrotic response called silicosis in the human lungs. Previous studies have indicated the role of membrane glycoproteins called scavenger receptors in binding of environmental particles. The scavenger receptors are classified into different classes (A-H) based on their structure and function. Class A scavenger receptors are critical in uptake of variety of ligands such as bacteria, acetylated lipoproteins and are typically found on macrophages, …

On The Edge, Hak Kyun Kim

Graduate Student Theses, Dissertations, & Professional Papers

My work is based on my continual fascination with the vessel. Stemming from its literal and conceptual uses: vessels serve, they preserve, they beautify, offer, invite, hold, hide, reveal, and present. With this concept, my work attempts to create new forms which are the vessels themselves and a myriad of possible relationships through different arrangements. To achieve these literal and conceptual uses of vessels, I paid special attention to placement and composition. I made tableware forms such as plates, cups, and mugs, setting them up into two metaphorical categories: “Before Serving” and “After Serving.” In the introduction, I will talk …

The study determined the relationship between perceptions that the Washington State county commissioners' hold of WSU Extension and their knowledge of WSU Extension. In addition, the study determined whether their perceptions, knowledge, and/or understanding of Extension are related to and thereby may have predictability to their willingness to provide the essential local funding to continue the educational programs Extension delivers. The study addressed the interest Washington State county commissioners/county council members have in funding WSU Extension, which directly affects the critical element of maximizing Extension's impact on society. As a publicly funded educational organization, WSU Extension faces an uncertain fiscal …

Evolution Of Roots, Robin Eileen Browning

Graduate Student Theses, Dissertations, & Professional Papers

Browning, Robin, M.A., June 2008 Integrated Arts and Education Evolution of Roots Chairperson: Karen Kaufmann Committee Members: Jim Kriley and Dorothy Morrison Somewhere a seed was planted long ago. It grew, changed and developed. It was sheltered, nurtured, fed and pruned. This seed took form, evolving to become a tiny sprout. The sprout was exposed to warmth and rain, time and sometimes pain, a process lending to further maturation. This in turn, once again, changed the youngster to a young sapling. Education, unfamiliar concepts, and exposure to new and different areas and elements developed this young sapling into an adult …
