Fighting and Foliage: Land System Dynamics in the Colombian Andes-Amazon region

Creator:: Murillo-Sandoval, Paulo J.
Abstract:: In the Colombian Amazon there has been a complex interplay of rebel groups’ control over land, drug trafficking, and absence of the Government of Colombia. Here, I use satellite remote sensing, ethnographic research and statistical models to provide insights into causal effect and causal mechanisms of land change and economic...

Mapping Nearshore Bathymetry with Spaceborne Data Fusion and State Space Modeling

Creator:: Forfinski-Sarkozi, Nicholas A.
Abstract:: Despite numerous techniques for measuring and estimating water depth, bathymetry in the nearshore zone is notoriously difficult to map. Dangerous sea states, noisy environmental conditions, and expensive survey operations, particularly in remote areas, contribute to the difficulties of obtaining data along the coast. Global datasets, derived mainly from satellite altimetry...

The Impact of Freeze-Thaw Cycles to the Physical and Biogeochemical Properties of Alaskan Permafrost Soils

Creator:: Rooney, Erin C.
Abstract:: Arctic warming is exposing thawing permafrost to repeated freeze-thaw, a disruptive process that can alter soil biogeochemistry and physical structure. To investigate the impact of permafrost exposure to freeze-thaw, soil response was tested across three scales: 2.5 cm³ aggregates, a forested hillslope, and two sites at contrasting latitudes. XCT imaging...

Climate-Smart Aquaculture: A Conceptual Framework for Evaluating Air-Breathing Fish for Sustainable Food Systems

Creator:: Ichien, Stephanie T.
Abstract:: The global demand for food is expected to double by 2050, presenting a need that is complicated by the many interrelated of pressures on the world’s natural resources from climate change, growing urban populations, and increasing development. As one of the fastest growing food production sectors, aquaculture is poised to...

New Metrics, Modeling Applications, and Observational Strategies for Snowpacks in Remote, Data-Limited, Mountain Environments

Creator:: Crumley, Ryan L.
Abstract:: The topics in this dissertation center on the snow processes that dominate mountain environments in the Western U.S. and Alaska, particularly in locations lacking long-term observational datasets or locales that are difficult to access in-person. Some are currently glacierized or have been glaciated in the recent past. Each of the...

Remote sensing of forest biomass dynamics using Landsat-derived disturbance and recovery history and lidar data

Creator:: Pflugmacher, Dirk
Abstract:: Improved monitoring of forest biomass is needed to quantify natural and anthropogenic effects on the terrestrial carbon cycle. Landsat's temporal and spatial coverage, fine spatial grain, and long history of earth observations provide a unique opportunity for measuring biophysical properties of vegetation across large areas and long time scales. However,...

Technologically Assisted Wayfinding : Comparing the Effects of Optical Head Mounted Displays and Hand-held Global Positioning Systems on Spatial Cognition and Wayfinding Performance

Creator:: Platosh, Paul
Abstract:: This study presents a comparison of differences in cognitive mapping as a result of navigating an unfamiliar space with GPS or with Google Glass. Using the Yerkes-Dodson law and attenuation theory, the study attempts to uncover how attention is diverted or focused through each of these wayfinding platforms. In addition...

Are Bird Habitat Associations Consistent Across Space and Time?

Creator:: Rousseau, Josée S.
Abstract:: The concept of the fundamental niche is frequently used in ecology to define the set of environmental conditions needed by a species to survive and reproduce (Hutchinson 1957). In contrast, the realized niche constitutes the locations where a species actually occurred, which is a function of both the environmental (abiotic)...

Exploring urban parks: plant communities, visitor experiences, and manager perspectives in Portland, Oregon

Creator:: Talal, Michelle L.
Abstract:: Urban parks are biodiversity hotspots within cities and have the potential to provide a range of socio-cultural benefits for people, but may not always meet the needs and desires of park visitors. A variety of land use practices and environmental factors affect urban park biodiversity and vegetation structure, composition, and...

Supply Chain Management of Timber and Biomass from Mountain Pine Beetle Infested Forests

Creator:: She, Ji
Abstract:: Mountain pine beetle infested forests in the Rocky Mountain region raise complicated economic, environmental, and social impacts and pose severe forest management challenges to land managers and public and private landowners. Harvesting infested forest stands provides an opportunity to utilize otherwise wasted resources, mitigate economics losses to landowners, and generate...
