Lithic Design And Technological Organization In Housepit 1 Of The S7istken Site, Middle Fraser Canyon, British Columbia, Matthew Mattes

Graduate Student Theses, Dissertations, & Professional Papers

Archaeological research of Housepit 1 at the S7istken site in the Middle Fraser region of the British Columbia Plateau has been ongoing since the summer of 2010. Housepit 1 is one of eight housepits at the site, and to date it has been excavated in near entirety. This has provided a large faunal assemblage mostly comprised of stored salmon remains, and also a lithic assemblage that has proven to be a useful measure of late prehistoric lifeways from the perspective of technological organization and lithic design strategies. Housepit 1 was occupied twice between about 350-300 B.P., which is the proto-historic …

Impacts Of Urban Land Use Change On Sources Of Drinking Water In Kumasi, Ghana, Michael Kofi Eduful

Land use has a major influence on water quality, and the issue is of great concern in developing world urban areas where there are competing land uses. Kumasi, Ghana like most cities in the developing world, struggles to control and prevent urban water supply pollution through appropriate water resource protection measures that minimize or eradicate adverse impacts of land uses. Presently all rivers in the city are highly polluted, including the one where raw-water is obtained for treatment and supply of potable water. This study investigates how sources of drinking water are impacted by land use in Kumasi, the implications …

Testing The Utility Of Environmental Cluster Analysis Based Upon Biodiversity Surrogates Within Geographic Information Systems For Conservation Planning: A Case Study Of Inland Temperate Rainforest In The Northern Rocky Mountains, Matthew J. Heimel

Graduate Student Theses, Dissertations, & Professional Papers

Environmental surrogates have been proposed as a method for addressing a lack of taxonomic data in biodiversity conservation planning. These surrogates, used as variables in Geographic Information Systems (GIS) analysis, can be used in classification procedures to classify areas that are hypothesized to support or be able to support a targeted species or community. The peripheral range of the inland temperate rainforest’s (ITRF) in northwest Montana and northern Idaho was used as a case study for testing the utility of a method known as Environmental Cluster Analysis (ECA) within a GIS using abiotic environmental variables encompassing broad environmental attributes to …

Assessing The Determinants Facilitating Local Vulnerabilities And Adaptive Capacities To Climate Change Impacts In High Mountain Areas: A Case Study Of Northern Ladakh, India, Kimiko Nygaard Barrett

Graduate Student Theses, Dissertations, & Professional Papers

Climate change is increasingly redefining the dialectic exchange between human systems and ecological processes. While the rhetoric of climate change is articulated within broad arenas of governance and policy, the realities of climate change are experienced at the local scale. Effective adaptation measures must therefore be commensurate with local resources, needs and objectives while remaining aligned with larger decision-making efforts. The impacts of climate change are heterogeneous and vary with geographic context. Biophysical parameters interface with socioeconomic and political forces to greatly influence the outcome of climate-related risks at the local level. In the high mountains of the western Himalayas …

Synthesis And Biological Evaluation Of A Library Of Polyacetylene Compounds Based On An Antiprotozoal Natural Product From Cussonia Zimmermannii, John Hoody

Graduate Student Theses, Dissertations, & Professional Papers

Leishmaniasis is one of several tropical diseases classified as a ôneglected tropical diseaseö. Its global prevalence is 12 million people with an estimated at-risk population of 350 million people.1 Current treatments include antimonials, amphotericin B, pentamidine, and miltefosine. Access to these medications is often limited in the impoverished nations that Leishmaniasis predominantly affects. Drug resistance and toxicity are also significant drawbacks to the current treatments.3 Therefore, there is an immediate need for the research and development of novel therapeutic molecules and strategies to combat Leishmaniasis.

Assessing Alternative Methods For Monitoring Populus Tremuloides Following Restoration Treatments, Michael Fowler

Graduate Student Theses, Dissertations, & Professional Papers

A variety of alternative sampling methods, commonly known as “Distance Methods”, were tested to determine if they could be a better choice for monitoring Populus tremuloides (quaking aspen) regeneration following aspen restoration treatments. These methods were evaluated based on their ability to accurately and efficiently estimate three common aspen stand characteristics used to gauge aspen restoration treatment effectiveness: aspen regeneration density, browse pressure, and height class distribution. Distance Method accuracy and efficiency were compared to a standard fixed-radius plot sampling method in four treated aspen stands in western Wyoming. None of the Distance Methods fulfilled all of the requirements, which …

Quantifying The Influence Of Past Wildfires On The Severity And Size Of Subsequent Wildfires, Sean Aaron Parks

Graduate Student Theses, Dissertations, & Professional Papers

Wildfire is arguably one of the most important and widespread natural disturbance agents in western U.S. forests. It has a substantial impact on ecosystem structure and function by influencing soils, nutrients, carbon budgets, wildlife habitat, and vegetation. Wildfires also influence fuel amount, type, and structure, potentially influencing the severity and size of subsequent wildfires through site- and landscape-level feedback mechanisms. Until relatively recently, the ability to quantitatively evaluate how these feedback mechanisms operate has not been feasible because of data limitations (i.e. there has not been enough wildfire). However, due to increased fire activity over the last ~25 years, there …

Securing Food And Livelihoods: Opportunities And Constraints To Sustainably Enhancing Household Food Production In Santa Familia Village, Belize, Siobhan B. Lozada

Graduate Student Theses, Dissertations, & Professional Papers

Rural households play an active role in reorganizing their livelihood strategies to respond to external stresses and shocks. What is unclear is the extent to which rural households can remain resilient in the face of continued external stresses and how policy actions at larger scales can more effectively encourage rural food and livelihood sustainability. Economic and ecological stresses and shocks have negatively impacted livelihood security and wider economic stability in Belize. This has increased the number of people below the poverty line to 41.3 percent, who remain disproportionately located in rural areas. With a high degree of import dependency, global …

Analysis Of The Rocky Boy Reservation’S Border Formation 1885 To 1950, Brendan Arthur Hoover

Graduate Student Theses, Dissertations, & Professional Papers

The purpose of this thesis is to analyze the border formation of the Rocky Boy Reservation, which was established in 1916 and is the home of The Chippewa-Cree Tribe. This thesis examines how racialized discourse surrounding The Chippewa-Cree Tribe affected the creation and subsequently the geography of the Rocky Boy Reservation, which is located in north-central Montana near the Canadian border. U.S. Native American policies and their affects on the reservation’s geography are also examined. It is important to analyze discourse and U.S. Native American policy because both influenced the geography of the Rocky Boy Reservation, which significantly contributed to …

Metamorphic Evolution Of Precambrian Rocks In The Southern Highland Mountains, Montana, And Implications For Proterozoic Tectonics, David Alan Reioux

Graduate Student Theses, Dissertations, & Professional Papers

The southern Highland Mountains, located in southwest Montana, contain a diverse assemblage of high-grade metamorphic rocks cored by migmatized leucocratic orthogneiss, with garnet-sillimanite paragneiss and schist at structurally higher levels. Based on the structure of the metamorphic rocks, O’Neill et al. (1988) hypothesized that the southern Highland Mountains is a gneiss dome. This study evaluates the gneiss dome hypothesis by conducting a petrologic study of the metamorphic rocks in the southern Highland Mountains using thin section analysis and pseudosections to determine if spatial trends in metamorphic conditions consistent with those of gneiss domes exist. In total, six samples were selected …

Stepping Outside: The Shifting Subjectivities Of Post-Romantic Poetry, William John Soloy

Graduate Student Theses, Dissertations, & Professional Papers

This investigation traces the arc of fracturing and exteriorizing subjectivities in the post-Romantic poetries of Modernism and Postmodernism, ultimately considering the state of contemporary Postmodern subjectivity after the Language Poets. Focusing primarily on T.S. Eliot, John Ashbery, and Christian Hawkey, the thesis argues that the I/Other split associated with Romantic poetry’s idealized Othering of nature performs a major shift with the interiorizing fragmentation of the speaker(s) in “The Love Song of J. Alfred Prufrock.” The anxiety produced by this claustrophobic, internal splitting of voices reaches critical mass in the chorus of difficult-to-trace speakers of “The Waste Land,” causing a breach …

Assessing Ecological Condition Of Large Landscapes With Limited Human Impacts, William James Kleindl

Graduate Student Theses, Dissertations, & Professional Papers

Our ability to measure global climate change has generated dire predictions in global ecosystem conditions. These predictions have inspired efforts to develop assessment metrics that examine alterations in ecological condition resulting from climate dynamics. As climate change drives future watershed- or regional-scale assessment model development, many questions will need to be addressed concerning potential tool constraints. Chief among these will be: to what degree is ecosystem condition affected by anthropogenic disturbance, climate-driven disturbance or natural variability, both individually and in combination? As a first step toward assessing impacts on ecological condition resulting from climate driven spatial or temporal disturbance gradients, …

The Missouri Compromised, Kate Casper Walker

Graduate Student Theses, Dissertations, & Professional Papers

Recreation versus navigation. Flood control versus wildlife. Agriculture versus water quality. Arguments over Missouri River management have been spinning for decades, literally trapped by the 1940s ideas and engineering that transformed the river. The Missouri Compromised is a 30-minute documentary that asks its audience to weigh the social and environmental tradeoffs when engineering a tremendously powerful natural system. Once a passage for tradesmen and settlers into the West, as well as a dynamic and rich ecosystem, the Missouri River today bears the marks of humanity’s control. The six main-stem dams on the upper Missouri, and the 750-mile bank-stabilized navigation channel …

Use Of Climatic Water Balance Metrics As Site Productivity Predictors, Matthew Dilsworth Perry

Graduate Student Theses, Dissertations, & Professional Papers

Estimates of long-term forest site productivity are required to inform multiple forest management objectives including growth and yield assessments, silvicultural planning, and biomass/carbon projections. Estimates traditionally have been quantified in the form of site index by measuring the average height-age relationships of dominant and codominant trees or using regional site index equations. Site index implementation requires that trees are free from suppression and that height growth results from the integration of the biological determinants of growth. While useful in even-aged stands, early age height growth suppression is common in uneven-aged forest structures making existing site indices difficult to assess. Additionally, …

Second-Dialect Acquisition In Southwestern Pennsylvania, Lisa Marie Sprowls

Graduate Student Theses, Dissertations, & Professional Papers

This thesis presents an analysis of second-dialect acquisition of Pittsburgh English phonological features. Pittsburgh English is the dialect spoken in southwestern Pennsylvania. There are two phonological features unique to the dialect: (i) the [ɔ] realization of the low-back vowel merger and (ii) monophthongal /aw/ (Johnstone et al. 2002). The current study is based on speech data collected from nine participants, native speakers of other dialects of English who now live in southwestern Pennsylvania. This analysis shows that these two phonological features can be acquired. This is the first study to examine Pittsburgh English as a second-dialect. Participants read a word …

Modeling Northern Goshawk (Accipiter Gentilis) Nesting Habitat On The Lewis And Clark National Forest Using Eigenvector Filters To Account For Spatial Autocorrelation, Morganne Marie Lehr

Graduate Student Theses, Dissertations, & Professional Papers

Habitat suitability modeling has become a valuable tool for wildlife managers to identify areas of suitable habitats for management and conservation needs. The Northern goshawk (Accipiter gentilis) has been the focus of many modeling efforts, however, the current models guiding goshawk management on the Lewis and Clark National Forest may not fully capture the unique habitat characteristics that the goshawk is actually selecting for nesting habitat. Therefore, the first objective of this study was to explore the use of Maxent for modeling suitable goshawk nesting habitat on the Lewis and Clark National Forest in central Montana. However, goshawk territoriality and …

Emerging Models In Environmental Volunteerism: The Domestic Volunteer Vacation, John Andrew Stegmaier

Graduate Student Theses, Dissertations, & Professional Papers

For well over two decades, land management agencies in the U.S. have experienced trends of flat if not otherwise declining budgets with which to fulfill their respective missions. Consequently, public land management agencies at various levels have sought creative strategies such as using volunteers to extend quality services without incurring added expense. An increasingly popular form of multi-day volunteer engagements, often referred to as a ‘volunteer vacation,’ is nearly absent from the literature when it comes to domestic project settings as opposed to international and often exotic locales.

A qualitative research study was conducted in the summer of 2013 on …

Graduate Student Theses, Dissertations, & Professional Papers

Opportunity, Montana is a small town within the 300 square mile Anaconda Smelter Superfund site in Western Montana. Waste from 100 years of ore processing has impacted the area. Arsenic exceeds Montana drinking water standards within the aquifer system feeding residential wells of Opportunity, causing resident concern about current and future safety of drinking water. The project described in this paper engages with this context from an environmental justice (EJ) perspective that views meaningful participation of affected communities as integral for sound and democratic decisions about environmental risks. Because Opportunity residents are left out of important decision making processes regarding …

Ecology Of Juvenile Salmon In Large Floodplain Rivers: The Influence Of Habitat Modification By Beavers (Castor Canadensis) On Salmon Growth And Production, Rachel Lanelle Malison

Graduate Student Theses, Dissertations, & Professional Papers

I investigated the influence of beavers on aquatic floodplain habitats and determined how juvenile salmon habitat use, growth, survival, movement, and production varied by habitat type in a large alluvial floodplain of the Kwethluk River in western Alaska. I also compared juvenile salmon production at the floodplain scale in the Kwethluk River (with beavers), to a very similar salmon river in Kamchatka (the Kol) that has no beavers.

Beavers modified 87.5% of the aquatic off-channel habitat of the Kwethluk River, which was composed of three successional stages of beaver ponds (early-, mid-, and latesuccessional), and beaver-influenced spring brooks. Early-successional ponds …

Agricultural land and water use has modified natural flow regimes in the western US. Understanding the effect of agricultural water use on streamflow is critical to effective water management and is often limited by the available data record. This investigation evaluates agricultural water use and streamflow in the Smith River watershed (SRW), a semi-arid agricultural watershed located on the eastern slope of the northern Rocky Mountains in west-central Montana. Questions motivating this study include: (1) Has agricultural water use modified streamflow on the Smith River? (2) What aspect of agricultural activity in the Smith River watershed is having the greatest …

Escape Probability: An Alternative Risk Metric To Support And Evaluate Wilderness Fire Management Decisions, Kevin Matthew Barnett

Graduate Student Theses, Dissertations, & Professional Papers

Inside many U.S. federally designated wilderness areas, fire suppression is the dominant management strategy largely due to the risk that fires pose to resources adjacent to the wilderness boundary. Opportunities to exploit the fuel treatment and risk-mitigation benefits of allowing wilderness fires to burn are foregone when ignitions are suppressed. Existing risk-based metrics (e.g. burn probability) produced from wildfire simulation models were not designed to inform management of wilderness fires. They focus on the management of fuels, or on suppression resource allocation, not managing ignitions through monitoring strategies for resource benefits. The purpose of this research was to develop a …

"Conspicuous Consumption:" Germs And Climate Cures In Denver, 1882-1915, Sydney Rene Gwinn

Graduate Student Theses, Dissertations, & Professional Papers

This thesis argues that the health-seeker’s quest for climatic cures persisted after the germ theory of disease began to alter medical approaches to tuberculosis after its announcement in 1882. Buoyed by anti-modern sentiments and a lack of effective medicinal interventions, physicians continued to recommend that tuberculosis patients travel to Denver to seek recovery in a healthier climate. In turn, Denver’s polity and public health approaches were shaped by the influences of the migration of tuberculosis patients to the city. After 1882, new approaches focused on sanitation and isolation began to take hold among physicians and public health reformers who worked …

Supporting Transitions To Resilient Irrigation Systems: Findings From Southern Kyrgyzstan, Peter Michael Igoe

Graduate Student Theses, Dissertations, & Professional Papers

This thesis presents findings from research conducted in Southern Kyrgyzstan, which followed nongovernmental organization (NGO) efforts to support climate change adaptation, and to support more “resilient” community-managed irrigation systems. Findings suggest that current NGO partnerships with Water User Associations (WUAs) frequently amount to financial and technical transactions, to preserve inherited infrastructure and resist disturbance. “Enhancing resilience” is pursued in an effort to maintain existing technical configurations of canals and water resources, despite altered socio-political and environmental conditions. Findings suggest increasing disassociation between irrigation constituents and the institutions and managers that are supposed to direct their grievances through legitimate democratic channels. …

Tourism On A Scenic Byway: Destination Image And Economic Impacts Of The Beartooth Highway, Jacob Daniel Jorgenson

Graduate Student Theses, Dissertations, & Professional Papers

Many tourism destination managers know who their visitors are and how they are perceived by them. However, when new destinations begin to take shape, understanding these perceptions and meeting the expectations of visitors can be a difficult task. Destination image provides the ability to explore the perceptions of visitors at a tourism place. One such place the Beartooth Highway in south-central Montana and north-central Wyoming is a scenic byway that reaches nearly 11,000 feet in elevation. Previously, little to no research has been conducted regarding travelers that frequent this region. The purpose of this study was to understand the destination …

Comparison Of Wild-Domestic Sheep Interaction Policies In Bighorn Disease Outbreak Locations In The Continental U.S., 1990-2010, Tristan Howard

Graduate Student Theses, Dissertations, & Professional Papers

For over 100 years, disease has significantly limited bighorn sheep (Ovis canadensis) in the western U.S. Interaction with domestic sheep (Ovis aries) has been a primary cause of fatal bighorn disease (typically pneumonia), which has severely reduced or eliminated entire populations. Various wild-domestic sheep interaction policies exist to address the disease problem. In this analysis, six case study locations are compared and analyzed in an effort to evaluate policy efficacy. Locations examined and their bighorn die-off dates include: the Tobin Range, NV (1991); Aldrich Mountain, OR (1991); the Highland/Pioneer Mountains, MT (1994-1995); the Tarryall/Kenosha Mountains, CO (1997-2000); the Hays Canyon …

If Rocks Could Talk: Using Central Place Foraging Theory In Lithic Production And Utilization Research, Sara Hocking

Graduate Student Theses, Dissertations, & Professional Papers

This research addresses microeconomic decision making during the Fur-Trade Occupation at Housepit 54 of the Bridge River Site. Specifically, it addresses the lithic production in regard to field processing and technological investment at the site. Field processing considers the importance of cost in transporting lithic raw material, while technological investment examines the amount of retouch and usewear based upon the distance from the quarry. The research tests the hypothesis that: the farther away the quarry is from the village site, the more flakes will be dominated by late stage reduction while the extent of retouch and usewear per tool will …
