Coupling Biophysical Complexity And Forest Metabolism In A Floodplain Landscape, Peter Davis

Graduate Student Theses, Dissertations, & Professional Papers

Floodplains are biophysically complex systems that are considered among the most productive and biodiverse ecosystems on Earth. Until recently, quantitative assessment of the relationship between complexity and terrestrial production has been constrained by technological limitation. To address how floodplain biophysical complexity and ecosystem function are related, I employed remote sensing, GIS, and spatial analyses to quantify and couple metrics of complexity and terrestrial production, as well as explore the relationship among complexity, vegetation structural diversity, and terrestrial primary productivity. The study site is a 6.75-km by 1.75-km portion of the Bitterroot River floodplain near Carlton, MT upon which 551 sample …

Performing Whale-Watching In Juneau, Alaska, Chelsea Karthauser

Graduate Student Theses, Dissertations, & Professional Papers

Nature-based tourism activities provide special contexts for human-wildlife interaction. In Juneau, Alaska, summertime tourists seek encounters with humpback whales, hundreds of which feed seasonally in Southeast Alaska’s coastal waterways. Tourists support a thriving whale-watching industry in the region. Voices in nature-based tourism studies, departing from prior rigid conceptualizations of tourism, have identified the need to investigate activities using innovative frameworks to address the tourism experience as an ongoing and fluidly constructed phenomenon. The purpose of this study is to construct a new understanding of nature-based tourism using a performance metaphor. The flexibility provided in a metaphorical approach allows for a …

The Practice Of Cartography: Imagining World Art Studies After Eurocentrism, Aja M. Sherrard

Graduate Student Theses, Dissertations, & Professional Papers

As the discipline of art history becomes increasingly global, the prevalence of European systems of thought and the supremacy of European systems of value in the way that we record, synthesize, teach, and preserve history have become increasingly apparent. This primacy of European systems of value, what we may call Eurocentrism, can be reduced to a problem of singularity: the belief in a single canon, a single timeline, or a single hegemonic center. Taking as subject; the theoretical infrastructure of the discipline itself, the Eurocentrism that has shaped it, and the past twenty years of postcolonial discourse, this paper seeks …

Collaborative Problem-Solving For Environmental Justice, Sophie C. Wolfram

Graduate Student Theses, Dissertations, & Professional Papers

An extensive body of environmental justice literature has demonstrated repeatedly what impacted communities have long known from experience, that environmental pollution including groundwater threats, diesel particulate matter, toxic releases, pesticide use, and hazardous waste sites, disproportionately burdens people of color and low-income communities. The environmental justice movement seeks to bring about equal protection of all people from environmental hazards, including equal enforcement of environmental laws and regulations. Advocacy within the movement has frequently adopted oppositional framings with respect to the state; however, collaborative approaches to environmental justice problem-solving have become more common, especially as states increasingly recognize environmental justice in …

Predicting Habitat Distribution For Five Rare Plant Species Within The Blackfoot Swan Landscape Restoration Project, Annalisa Suzan Ingegno

Graduate Student Theses, Dissertations, & Professional Papers

This study predicted rare-plant habitat at the landscape scale. Using the Maximum Entropy (MaxEnt) algorithm, relationships to and between each environmental variable were quantified for five species in the Blackfoot Swan Landscape Restoration Project (BSLRP) study area in western Montana. This project is part of a greater vegetation assessment for BSLRP that utilizes remotely sensed products for planning and management purposes. The five rare plant species studied in this analysis were common camas (Camassia quamash), clustered lady’sslipper (Cypripedium fasciculatum), western pearlflower (Heterocodon rariflorum), Howell’s gumweed (Grindelia howellii), and crested shieldfern (Dryopteris cristata). Rare plant models typically do not address dispersal …

Set The Net: The Heritage Significance Of Fish Camp And Wild Salmon In Bristol Bay, Alaska, Sarah Jane Braund

Graduate Student Theses, Dissertations, & Professional Papers

In over 10 years of environmental and socioeconomic studies surrounding the controversial Pebble Limited Partnership mine project design and permitting, commercial salmon fishers’ voices in Bristol Bay, Alaska remain unheard. To meaningfully participate in cultural resource management decision-making that affects them, communities need to speak, yet fisher communities rarely have an established voice. This dissertation uses critical collaborative ethnography and Indigenist research paradigms to describe how the recognition of living heritage communities can be facilitated through the identification of ethnographic landscapes. Such landscapes reflect the meaningful relationship of culture and place, concepts that are currently under-represented in Alaska. Not only …

Enhancing Conservation With High Resolution Productivity Datasets For The Conterminous United States, Nathaniel Paul Robinson

Graduate Student Theses, Dissertations, & Professional Papers

Human driven alteration of the earth’s terrestrial surface is accelerating through land use changes, intensification of human activity, climate change, and other anthropogenic pressures. These changes occur at broad spatio-temporal scales, challenging our ability to effectively monitor and assess the impacts and subsequent conservation strategies. While satellite remote sensing (SRS) products enable monitoring of the earth’s terrestrial surface continuously across space and time, the practical applications for conservation and management of these products are limited. Often the processes driving ecological change occur at fine spatial resolutions and are undetectable given the resolution of available datasets. Additionally, the links between SRS …

Assessing The Character Of Place To Guide Geotourism In Montana: A Case Study Of Whitefish And White Sulphur Springs, Montana, Michael E. Tipton

Graduate Student Theses, Dissertations, & Professional Papers

In 2007 the governor’s Montana Tourism Advisory Council adopted the Montana Tourism and Recreation Charter. Its guiding principle of geotourism pledged to sustain and enhance the character of the places that the people of Montana call home. How can the state’s efforts to keep this pledge be assessed when “character of place” has never been clearly defined or understood in detail? To keep this pledge, and chart the future of geotourism in the state, it was important to clarify what is meant by character of place and identify the full range of present and potential problems that threaten the integrity …

Participatory Web Gis Design – A Sustainable Recreation Decision Support System For Missoula County, Nathanael R. Wold

Before Abandonment: Social Change In Pre-Colonial Housepit 54, Bridge River Site (Eerl4), British Columbia, Kathryn L. Bobolinski

Graduate Student Theses, Dissertations, & Professional Papers

Housepit 54 at the Bridge River pithouse village in south-central British Columbia provides a glimpse into the complex cultural practices that occurred in this area in the past. This village, which includes approximately 80 semi-subterranean structures, was occupied during four periods, approximately 1800- 1600 cal. B.P., 1600-1300 cal. B.P., 1300-1000 cal. B.P. and 500-100 cal. B.P, firmly placing the site within both a historic and a pre-Colonial context. The two pre-Colonial floors, IIb (1288-1058 cal B.P.) and IIa (1184-1050 cal B.P.), that represent the occupation of Housepit 54 directly prior to the pre-Colonial villages abandonment are the focus of this …

Do The Impacts Of Natural Amenities On Population Change Differ In New West Versus Old West Places?, Shefije Miftari

Graduate Student Theses, Dissertations, & Professional Papers

This research examines how location-specific amenities affect rural population growth given demographic and cultural differences found in New West and Old West census tracts in the mountain west. In the 1970s, the United States experienced an unexpected turnaround in migration patterns as households began moving from urban to rural areas. Identifying different drivers of rural population growth is necessary for planning for and managing future growth in ways that optimize economic benefits while minimizing potential environmental degradation.

Using cross-sectional, specially constructed, spatially explicit data, this research identifies how determinants of population growth differ in New West versus Old West census …

What The Gringos Brought: A Critical Examination Of A Privately Protected Area In Chilean Patagonia, Elena Louder

Graduate Student Theses, Dissertations, & Professional Papers

Neoliberal ideology increasingly underscores many mainstream efforts to conserve biodiversity. This research explores this convergence through an in-depth case study of a privately owned park located in Chilean Patagonia. In two complementary chapters, I assess the social and cultural impacts of the project, and examine the role of discourse in the process of communicating and constructing the park. In the first chapter I draw from interview data collected from September through December of 2016 and explore the perspectives of local people with a variety of relationships to the project. In the second I employ a critical discourse analysis of park …

Assessing Riparian Ecosystem Condition And Monitoring Recovery From Natural And Anthropogenic Disturbance, Rachel Powers

Graduate Student Theses, Dissertations, & Professional Papers

Riparian ecosystems are the transition zones between river systems and uplands. They provide many valuable ecological functions including creating habitat for wildlife, stabilizing banks from erosion and providing a buffer that prevents excess nutrients from entering streams. Fires and other disturbances alter the function of these ecosystems. Currently, there is a lack of broadly used standardized assessments and monitoring methods in riparian areas within our current water policy framework. This study aims to examine this gap in riparian ecosystem protection by reviewing the assessment methods currently in use, selecting one method for field testing, and analyzing the effort involved in …

Potential Contrasts In Co2 And Ch4 Flux Response Under Changing Climate Conditions: A Satellite Remote Sensing Driven Analysis Of The Net Ecosystem Carbon Budget For Arctic And Boreal Regions, Jennifer D. Watts

Graduate Student Theses, Dissertations, & Professional Papers

The impact of warming on the net ecosystem carbon budget (NECB) in Arctic-boreal regions remains highly uncertain. Heightened CH4 emissions from Arctic-boreal ecosystems could shift the northern NECB from an annual carbon sink further towards net carbon source. Northern wetland CH4 fluxes may be particularly sensitive to climate warming, increased soil temperatures and duration of the soil non-frozen period. Changes in northern high latitude surface hydrology will also impact the NECB, with surface and soil wetting resulting from thawing permafrost landscapes and shifts in precipitation patterns; summer drought conditions can potentially reduce vegetation productivity and land sink of atmospheric CO2 …

School Change For Sustainability, Ryder Delaloye

Graduate Student Theses, Dissertations, & Professional Papers

The welfare of current and future generations is diminished due to unprecedented levels of ecological degradation that is a result of accelerating levels of per capita consumption. Sustainability education is being widely embraced as an applied strategy for addressing both unchecked consumption and environmental degradation (Brown, 2003). Yet, little is known about how schools adopt and implement sustainability education. The means by which to engage and foster sustainability education is not well researched. This qualitative research study seeks to address the following research question: How did students and faculty at each school site go about the process of creating and …

Does Timing Of Herbicide Use Influence Rates Of Germination Or Seedling Biomass Of Native Plants Used For Restoration?, Christine Mcmanamen

Graduate Student Theses, Dissertations, & Professional Papers

Invasive plants can negatively impact native grasslands by changing their species composition, productivity, and function. Managers commonly use herbicides as a control method; however, this practice can lead to secondary invasion by other non-native invasive plants, unless measures are taken to promote natives. Because of this, managers often seed native plants after spraying herbicides. There is evidence, however, that chemical control of invasive plants may reduce the effectiveness of subsequent seed-addition treatments, but there is currently little quantitative information on optimal timing between spraying and seeding or on variation in herbicide sensitivity among native plants commonly used in seed mixes. …

Utilization Of Landsat Imagery To Assess The Impacts Of Oil And Gas Extraction On The Tazovsky Peninsula, Siberia, Nicholas B. Kline

Graduate Student Theses, Dissertations, & Professional Papers

Climatic warming of the Arctic is leading to landscape change through cascading biophysical feedbacks; development, such as oil and gas exploration and extraction, can accelerate or worsen these impacts. Due to restricted access to oil and natural gas fields, in situ environmental impact studies are only allowed in some regions. Satellite imagery analysis provides a mean for assessing impacts in areas with limited access. The Yamburg oil and gas field in western Siberia serves as a case study to assess the effects of infrastructure on an Arctic landscape.

This project quantifies the land-cover disturbance that occurred during the development and …

Enclosed From All Sides: Reading Contact And Ambivalence In The Imaginary Al-Andalus Of Hrotsvit's The Passion Of Pelagius And The Song Of Roland, Briana J. Wipf

Graduate Student Theses, Dissertations, & Professional Papers

Hrotsvit of Gandersheim’s The Passion of Pelagius and The Song of Roland have never been read together in terms of their shared engagement with the Muslim other in the Iberian Peninsula, known during the Middle Ages as Al-Andalus. This project is a comparative reading of the texts’ approach to the presentation of an imaginary Al-Andalus as a space of alterity. The texts’ emphasis on imaginative as opposed to accurate portrayals of Andalusian history and Islamic culture suggests their engagement with a process of Christian identity-building, where the “Christian,” as portrayed in each text, is defined against and in comparison to …

40 Trees: The Quest To Save Whitebark Pine On The Flathead Indian Reservation, Andrew S. Graham

Graduate Student Theses, Dissertations, & Professional Papers

When it comes to managing natural resources in the face of global climate change, sometimes localized action is best. Rick Everett spent a lot of time in western forests - first as a ski patroller and logger and then as an ecologist - before landing as a professor at a tribal community college on the Flathead Indian Reservation. Now he faces a challenging new question: How do you save a tree species that is ecologically valuable to the forest and culturally valuable to Native American tribes, but is being pushed toward extinction by forces varied, deadly and driven by climate …

Performance Measures Of Road Crossing Structures From Relative Movement Rates Of Large Mammals, Adam Andis

Graduate Student Theses, Dissertations, & Professional Papers

In recent decades, there has been an increase of engineering projects that seek to mitigate the barrier effect roads impose on wildlife by installing wildlife crossing structures that promote permeability of the road corridor. The 41 fish and wildlife crossing structures installed along a 90km stretch of US Highway 93 on the Flathead Indian Reservation in western Montana, represent one of the most extensive of such projects in North America. As mitigation efforts are increasingly considered and implemented in road construction projects, the need to assess these structures’ effectiveness grows. This study is the first to compare observations of animal …

Baseline Study Of Recovering Headwater Streams In The Sapphire Mountains, Western Montana, Morgan Vinyard

Graduate Student Theses, Dissertations, & Professional Papers

Many riparian areas in the western United States have been degraded by grazing and logging. In the year 2000, the Montana Department of Environmental Quality (DEQ) re-initiated an effort to identify and characterize reference streams, or least impacted streams in each region of the state. In Montana’s Bitterroot Valley, most streams have been impacted by grazing, irrigation, and timber production. The Montana DEQ has not been able to identify reference streams in the Sapphire Mountains on the east side of this valley. MPG Ranch, located on the west-facing slopes of the Sapphire Mountains and purchased in 2009 by a conservation-minded …

A Comparison Of The Utility Of Craniometric And Dental Morphological Data For Assessing Biodistance And Sex-Differential Migration In The Pacific Islands, Brittney A. Eubank

Graduate Student Theses, Dissertations, & Professional Papers

Genetic analysis of maternally-inherited mitochondrial DNA and the paternally-inherited Y-chromosome yield contrasting pictures of movement of peoples into the Pacific Islands. A possible explanation for this discrepancy is a matrilocal residency pattern practiced by early Pacific settlers, in which Melanesian men were brought into settler communities to intermarry with local women, yielding a higher intrapopulation variance and lower interpopulation variance exhibited in males compared to females. This research investigates the possibility of sex-differential migration in the Oceanic populations of Easter Island, Fiji, Guam, Mokapu, and New Britain through analysis of biodistance based on dental morphological trait frequencies and craniometric measures …

Bicycle Mobility In Glacier National Park: Assessing Going-To-The-Sun Road Travelers' Attitudes, Knowledge, And Perceptions Of Bicycling, Brian G. Battaglia

Graduate Student Theses, Dissertations, & Professional Papers

The central aim of this thesis assessed whether Going-to-the-Sun Road (GTSR) travelers have a positive or negative association with roadway bicycling and the degree of public support for GTSR bicycling in Glacier National Park (GNP). Secondarily, this thesis tested a control and treatment group’s knowledge of roadway cycling laws to determine the effectiveness of a “Bicycles May Use Full Lane” sign and brochure, which both reflected Montana’s cycling laws. Finally, an analysis of the necessity of GNP’s partial bicycle restriction on the GTSR was conducted by comparing the characteristics of two road segments using GIS, and by assessing the attitudes, …

The Next Billion: Lessons In Off-Grid Electricity Development From The Global South, Peter Mcdonough

Graduate Student Theses, Dissertations, & Professional Papers

Today about a third of the world’s population has no access to electricity, and another third has only limited access. Driven by the push for development on one hand and the reality of climate change on the other, a combination of for-profit companies, NGOs, missions, and aid organizations is looking for the silver bullet to sustainable electricity development. In order to understand the challenges facing off-grid electricity projects I used recent literature in the form of peer-reviewed journals, agency reports, news articles, and technical documents; stakeholder interviews; and on-site observations in selected case studies in Nepal, India, and Tanzania. In …

Hazardready – A Geographically Based Natural Hazard Education And Preparedness Web Application, Carson C. Macpherson-Krutsky Ms.

Graduate Student Theses, Dissertations, & Professional Papers

Earthquakes, floods, wildfires, and other natural disasters are inevitable and costly both in terms of lives lost and money spent on recovery. Scientific research on natural hazards is widely shared within the scientific community, but is less often made more widely accessible, as methods or pathways for providing scientific natural hazard information and data in non-technical language are limited. Priorities for imparting hazard information include: 1) scientific accuracy, 2) spatial granularity, 3) integration of information about all relevant hazards, 4) nontechnical content, 5) appropriate preparedness activities, and 6) engagement with existing disaster response and mitigation capabilities. In response to these …

Evaluation Of Social Preferences For Woody Biomass Energy In The Us Mountain West, Robert Marshall Campbell

Graduate Student Theses, Dissertations, & Professional Papers

There are substantial opportunities for mechanized thinning treatments to reduce the likelihood of severe and damaging wildfires and improve forest health in the public forests of the Western US. These treatments could also produce woody biomass that can be used to generate renewable energy and displace fossil fuels. Although woody biomass energy is often not financially competitive with fossil fuels, financial analysis alone is an incomplete method of comparison because of the significant negative environmental externalities imposed by the burning of fossil fuels, and potential positive externalities associated with woody biomass energy generation. It is possible that when non-market costs …
