Satellite Microwave Assessment Of Northern Hemisphere Lake Ice Phenology From 2002 To 2015, Jinyang Du, John S. Kimball, Claude Duguay, Youngwook Kim, Jennifer D. Watts

Numerical Terradynamic Simulation Group Publications

A new automated method enabling consistent satellite assessment of seasonal lake ice phenology at 5 km resolution was developed for all lake pixels (water coverage  ≥  90 %) in the Northern Hemisphere using 36.5 GHz H-polarized brightness temperature (T_b) observations from the Advanced Microwave Scanning Radiometer for EOS and Advanced Microwave Scanning Radiometer 2 (AMSR-E/2) sensors. The lake phenology metrics include seasonal timing and duration of annual ice cover. A moving t test (MTT) algorithm allows for automated lake ice retrievals with daily temporal fidelity and 5 km resolution gridding. The resulting ice phenology record shows strong …

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

Graduate Student Theses, Dissertations, & Professional Papers

Sustainable recreation ensures that local communities benefit from the effects of recreation. A recreation decision support system (RDSS) is a common way for people to gather information about an area they are about to visit. This research explores: 1) how well can local representatives’ knowledge concerning appropriate recreation behaviors be incorporated into a WebGIS that will serve as a RDSS, 2) what layers, activities, and information do participants want to include in a RDSS, and 3) how well does the ArcGIS Online perform in incorporating representatives’ knowledge of areas of significance for a RDSS?

Recreationalists in Missoula County, Montana, have …

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 …

Concussion Knowledge Of Missoula Youth Hockey Participants And Their Parents, Samantha Riordan

Graduate Student Theses, Dissertations, & Professional Papers

Abstract:

Background: The Dylan Steigers Protection of Youth Athletes Act (DSPYAA) was passed by Montana legislature in 2013 which calls for mandatory concussion education of coaches, parents, and athletes. This law only applies to school sponsored sports, excluding those involved in youth sports organizations (YSO), such as youth hockey.

Hypothesis: Participating youth athletes and parents will not be able to identify signs and symptoms of a concussion and will not be able to identify future consequences of a poorly managed concussion.

Study Design: Cross sectional survey. Level of Evidence: Level 4

Methods: A descriptive questionnaire, Concussion Knowledge in Youth Sports …

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 …

Mapping Arctic Tundra Vegetation Communities Using Field Spectroscopy And Multispectral Satellite Data In North Alaska, Usa, Scott J. Davidson, Maria J. Santos, Victoria L. Sloan, Jennifer D. Watts, Gareth K. Phoenix, Walter C. Oechel, Donatella Zona

Numerical Terradynamic Simulation Group Publications

The Arctic is currently undergoing intense changes in climate; vegetation composition and productivity are expected to respond to such changes. To understand the impacts of climate change on the function of Arctic tundra ecosystems within the global carbon cycle, it is crucial to improve the understanding of vegetation distribution and heterogeneity at multiple scales. Information detailing the fine-scale spatial distribution of tundra communities provided by high resolution vegetation mapping, is needed to understand the relative contributions of and relationships between single vegetation community measurements of greenhouse gas fluxes (e.g., ~1 m chamber flux) and those encompassing multiple vegetation communities (e.g., …

Future Decreases In Freezing Days Across North America, Michael A. Rawlins, Raymond S. Bradley, Henry F. Diaz, John S. Kimball, David A. Robinson

Numerical Terradynamic Simulation Group Publications

This study used air temperatures from a suite of regional climate models participating in the North American Climate Change Assessment Program (NARCCAP) together with two atmospheric reanalysis datasets to investigate changes in freezing days (defined as days with daily average temperature below freezing) likely to occur between 30-yr baseline (1971–2000) and midcentury (2041–70) periods across most of North America. Changes in NARCCAP ensemble mean winter temperature show a strong gradient with latitude, with warming of over 4°C near Hudson Bay. The decline in freezing days ranges from less than 10 days across north-central Canada to nearly 90 days in the …
