Human-Bear Conflicts In Western Montana: Mapping Attractants And Prevention Efforts, Jessica Nichole Reyes

Graduate Student Theses, Dissertations, & Professional Papers

Human-bear conflicts (conflicts) are rising across North America, largely due to the expansion of the wildland-urban interface into bear habitat. These conflicts are driven by ecological and human factors, including habitat fragmentation, loss of natural food sources and the widespread availability of human-related attractants such as garbage, fruit trees, and bird feeders. While studies increasingly examine the ecological and spatial predictors of conflicts, fewer have explored how attractant types, land cover changes, and local geography shape conflict trends. Montana communities have long managed bear conflicts, but recent increases in incidents and human-caused bear mortalities—alongside expanding grizzly bear populations—have prompted growing …

When Emotions Flare: Solar Rhythms, Emotions And Cycles Of Political Revolution, Andreas Hernandez, Carolina Zilli Vieira, Alexandra Smith, Rebecca Olson

Geography and Environmental Studies Faculty Publications

Revolutions are among the most transformative events in human history. Analyzing 395 revolutionary episodes from 1900 to 2014, we find that major waves cluster around solar maxima - periods of intensified geomagnetic activity. Drawing on biomedical research linking geomagnetic disturbances to cardiovascular and stress regulation, and thus to emotional states, we propose that solar cycles modulate the affective ecologies within which revolutions arise. Solar activity may accelerate, shape, and amplify revolutionary cycles by heightening emotional climates and tipping fragile systems toward mass mobilization. This reframes revolutions as planetary events - entanglements of political conflict, embodied emotion, and cosmic …

Integrating Indigenous Values And Community Strengths To Achieve Indigenous Food Sovereignty And Community Well-Being In The Ka’A’Gee Tu First Nation, Northwest Territories, Jennifer K. Temmer

Theses and Dissertations (Comprehensive)

Northern Indigenous communities face disproportionate impacts from interconnected challenges related to climate change, food security, health, and cultural preservation, that threaten traditional food systems and practices. While there is a growing recognition of the importance of community-driven solutions, existing frameworks fail to integrate Indigenous values and local priorities effectively. This research addresses this gap by exploring how the Ka’a’gee Tu First Nation (KTFN) is responding to these crises through climate change adaptation efforts focused on food system sustainability as a pathway to self-sufficiency and community well-being. To contribute to these efforts, this dissertation uses Participatory Action Research to facilitate community-driven …

Nature For All? Assessing Equitable Public Access To National Urban Parks In Canada: A Comparative Analysis, Andrew Tenute

Theses and Dissertations (Comprehensive)

The number of health challenges is rising both globally and in Canada. Research consistently shows that time spent in nature can mitigate some of these health challenges, offering significant mental, physical, and well-being benefits. Parks and protected areas in Canada, including the expansion of the National Urban Park (NUP) program by Parks Canada, provide valuable opportunities for nature-based engagement. However, access to these spaces is unjust, as many individuals face structural, intrapersonal, and interpersonal constraints. While prior studies have explored the motivations and well-being outcomes of women and Black, Indigenous, and People of Colour (BIPOC) individuals, there remains a limited …

Co-Creation, Interpretations And Engagement With A Movement-Based Symbol For Climate Justice: A Qualitative Inquiry, Kai Reimer-Watts

Theses and Dissertations (Comprehensive)

The climate crisis demonstrates with complete clarity the need for massive systems-level changes towards far more sustainable societies. Global and local emissions need to decline rapidly to mitigate intensifying climate breakdown, accompanied by climate and sustainability solutions, to secure a far more stable, safe, and just future for all people and all life. Within these changes, engaging in our communities is essential to support and co-create broader solutions to help advance more sustainable societies, reduce negative impacts of a changing climate, and to move towards cultures and systems that recognize natural limits and centre care for people and planet.

Unseen Connections: A Storymap Exploring Case Studies In Water-Energy Transitions And Environmental Justice, Alida Cantor, Elizabeth Bartholomew, Kate Berry, James Blair, Dustin Mulvaney, Nancee Hunter

Geography Faculty Publications and Presentations

Climate change is one of the most important challenges in the world today. Communities and decision makers at many levels, from local to international, are working to ensure that energy, water, and other societal infrastructures can transition and adapt to address climate change (IPCC, 2023). One major mitigation strategy involves the decarbonization of energy systems (Rockström et al. 2017). Despite wide recognition of the need to decarbonize globally, renewable energy infrastructures and technologies are often locally controversial, involving claims of environmental injustice and disputes over land and water (Cantor, Turley, and Maxfield 2023; Jerez, Garcés, and Torres 2021; Turley et …

Collaborative Governance And Hydrosocial Territorialization: Reaching Consensus On Salmon Restoration Goals In The Columbia River Basin, Thien-Kim Bui, Rebecca Mclain

Geography Faculty Publications and Presentations

Across the Cascadia bioregion, salmon and steelhead are ecological and cultural keystone species that contribute to and illustrate riverine health. Due to complex social, economic, and ecological relations over the past 150 years, many Columbia River Basin salmon and steelhead populations are now listed as threatened or endangered in the United States. This research uses the 2017–2020 Columbia Basin Partnership Task Force as a case study to understand how this collaborative governance effort of sovereign entities and nonsovereign stakeholders navigated competing water claims to reach consensus on aspirational qualitative and quantitative goals for salmon and steelhead restoration. Using semistructured interviews …

With the impact of climate change, the intensity and frequency of tornado events have been increasing. Enhancing tornado reconnaissance methods can comprehensively capture building damage and recovery data following tornado events and outbreaks, thereby strengthening community resilience against the threat of future tornado events. Advancements in tornado data reconnaissance research have embraced remote sensing techniques to assess building damage after tornado events, supplanting traditional reconnaissance methods relying on handheld cameras with GIS mapping. Community resilience research offers a groundbreaking perspective, stressing the importance of assessing buildings throughout their recovery cycle-from damage and functionality to recovery-and considering their socioeconomic stability in …

Land Target Detection Algorithm In Remote Sensing Images Based On Deep Learning, Wenyi Hu, Xiaomeng Jiang, Jiawei Tian, Shitong Ye, Shan Liu

Electrical & Computer Engineering Faculty Publications

Remote sensing technology plays a crucial role across various sectors, such as meteorological monitoring, city planning, and natural resource exploration. A critical aspect of remote sensing image analysis is land target detection, which involves identifying and classifying land-based objects within satellite or aerial imagery. However, despite advancements in both traditional detection methods and deep-learning-based approaches, detecting land targets remains challenging, especially when dealing with small and rotated objects that are difficult to distinguish. To address these challenges, this study introduces an enhanced model, YOLOv5s-CACSD, which builds upon the YOLOv5s framework. Our model integrates the channel attention (CA) mechanism, CARAFE, and …

Atmospheric Chemistry Experiment (Ace) V.5.3 Winds: Validation And Model Comparisons, Matthew Wyatt, Peter F. Bernath, Chris Boone, Leo Lavy, Ryan Johnson

Physics Faculty Publications

The Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) uses limb geometry to measure transmittance spectra of Earth's atmosphere by solar occultation. Line-of-sight wind speeds can be derived via Doppler shifts of molecular lines in infrared spectra. The wind look direction angles relative to geodetic north are derived from geometry. We validate the new ACE version 5.3 (v.5.3) line-of-sight winds with MIGHTI and meteor radar vector wind observations and find a -15 m s^-¹ (+15 m s^-¹) sunrise (sunset) shift above 80 km. We also compare line-of-sight winds from ACE-FTS v.5.2 and v.5.3 with vector winds from …

Rethinking Rural Identity: Reimagining Rural Politics, Matthew B. Kirk

Electronic Theses & Dissertations (2024 - present)

This work chiefly consists of a genealogical critique of rural identity. Tracing the development and deployment of the concepts of rurality and rural consciousness, I argue that our current depictions of rurality as “spatial other,” replete with its harmful stereotypes, stem from a misconception about the nature of power. Political theorists’ and political scientists’ appraisals of rurality suggest that the set of actions that define rural politics are a product of their relative powerlessness. Rural locales’ removal from the center of power in urban spheres means that rural politics is reduced to reactionary, violent, and conservative political thought and engagement. …

Livelihood Adaptive Strategies And Marginalization In Decision-Making: A Study Of Glacial Lake Outburst Flood (Glof) Vulnerable Communities In Northern Pakistan, Sobia Shah

Graduate Theses/Dissertations

This study examines livelihood adaptation strategies and the dynamics of marginalization in decision-making within communities vulnerable to Glacial Lake Outburst Floods (GLOFs) in Gilgit-Baltistan, Northern Pakistan. Grounded in a vulnerability framework encompassing exposure, sensitivity, and adaptive capacity, it addresses two objectives: identifying household and community-level adaptation strategies to GLOF risks and analyzing structural drivers of marginalization in adaptation decision-making. A mixed-methods design was used, combining a systematic review of GLOF measures in the Hindu Kush Himalaya (HKH) region with a household survey of 150 respondents in Hassanabad and Hoper valleys. Generalized Additive Models (GAMs) assessed how socio-demographic, economic, institutional, and …

Ensemble Machine Learning Approaches For Bathymetry Estimation In Multi-Spectral Images, Kazi A. Islam, Omar Abdul-Hassan, Hongfang Zhang, Victoria Hill, Blake Schaeffer, Richard Zimmerman, Jiang Li

OES Faculty Publications

Traditional bathymetry measures require a large number of human hours, and many bathymetry records are obsolete or missing. Automated measures of bathymetry would reduce costs and increase accessibility for research and applications. In this paper, we optimized a recent machine learning model, named CatBoostOpt, to estimate bathymetry based on high-resolution WorldView-2 (WV-2) multi-spectral optical satellite images. CatBoostOpt was demonstrated across the Florida Big Bend coastline, where the model learned correlations between in situ sound Navigation and Ranging (Sonar) bathymetry measurements and the corresponding multi-spectral reflectance values in WV-2 images to map bathymetry. We evaluated three different feature transformations as inputs …

High Antarctic Coastal Productivity In Polynyas Revealed By Considering Remote Sensing Ice-Adjacency Effects, Hilde Oliver, Jessica S. Turner, Alexandre Castagna, Henry Houskeeper, Heidi Dierssen

OES Faculty Publications

Ocean color-based estimates of Antarctic net primary productivity (NPP) have indicated low nearshore productivity in ice-adjacent waters, contrasting with coupled physical–biogeochemical models. To understand this discrepancy, we assessed satellite records of polynya NPP by comparing field data with two satellite imagery datasets derived using different processing schemes. Our results indicate historical underestimation of chlorophyll a for imagery obtained using default atmospheric correction processing within approximately 100 km of ice-covered coastlines due to adjacency effects. Using radiative transfer modeling, we find that biases in ocean color polynya observations due to adjacency effects correspond to the high albedo of ice and snow. …
