Scaling of Hyporheic Exchange Processes and Finding the Intermediate Sweet Spot

Creator:: Becker, Paige Sheridan
Abstract:: Hyporheic zones are important regions that reside below and along the sides of streams. Within this region, several ecosystem services are provided including stream temperature regulation, habitats for a large variety of species, pollutant removal, and nutrient cycling. Exchange between the hyporheic zone and stream occurs across multiple scales, but...

Role of the “Blue Paradiplomacy” in Cooperation over Transboundary Water Management

Creator:: Dzhakshylykova, Mira
Abstract:: In this research, the paradiplomacy concept is analyzed in terms of transboundary water cooperation and called "Blue Paradiplomacy", where two case studies: 1) the Great Lakes region and 2) the Central Asian region, are presented and compared. The concept of paradiplomacy is applied within the context of multi-level governance, and...

Climate Variability and Plant-Pollinator Networks in the Cascade Range, Oregon

Creator:: Vickers, Melinda
Abstract:: Worldwide, networks of plants and pollinators are faced with the threat of climate change. The extent of this threat and the degree of adaptability is not yet understood. In Oregon, climate change is predicted to bring hotter and drier summers which may have consequences for pollinators and the resources they...

Applying Object-Based Supervised Image Classification in Large-Scale Floodplain Monitoring

Creator:: Vito, Olivia
Abstract:: Large, alluvial rivers are naturally diverse, both in structural complexity and as drivers of landscape dynamics. Floodplains provide a mosaic of habitat types for aquatic, semi-aquatic, and terrestrial organisms and act as the framework for vital chemical processes to occur. In large part, this variety is due to the ability...

Ecotypic variation of Schoenoplectus pungens (Vahl) Palla in response to salinity and inundation

Creator:: Del Giudice Tuttle, Elena
Abstract:: Local adaptation in plants may hold the key to understanding the level of resilience of an ecosystem and probability of persistence of a species in the face of rapid anthropogenic changes in climate and disturbance regime. Clonal species are especially important in wetlands, one of our most productive and vulnerable...

Invasive Species in Riparian Habitats of Washington: Using Species Distribution Models to Guide Monitoring Efforts

Creator:: Smiley, Samantha N.
Abstract:: Riparian ecosystems provide critical habitat for a broad diversity of aquatic and terrestrial species. However, due to their connectivity along river corridors, and the tendency for people to build roads, infrastructure, and other settlements next to rivers, riparian ecosystems are vulnerable to colonization by invasive plant and animal species. Early...

Spatial relationships for vegetation in restored and reference salt marshes in the Salmon River Estuary, Oregon

Creator:: Chellew, Megan
Abstract:: In this thesis, the spatial patterns of vegetation and soils of reference and restored tidal marshes were compared to determine the extent to which restored sites differ from the reference site after 40 years of restoration. Vegetation surveys of 1m x 1m plots were conducted along previously-established transects of salt...

Spatio-Temporal Patterns of Tree Establishment in the M1 Meadow of the H.J. Andrews Experimental Forest

Creator:: Jones, Katherine E.
Abstract:: Montane meadows in the Cascade Range of Oregon have been declining due to tree establishment since records began. Montane meadow complexes in the H.J. Andrews Experimental Forest shrank by 60 to 75% from 1949 to 2005, but fine scale temporal and spatial processes of tree establishment in these meadows are...

Examining the Spatial Distribution of Park Access and Trajectories of Gentrification in Seattle, Washington 1990 - 2010

Creator:: Weems, Candice Michelle
Abstract:: This dissertation examines the spatial distribution of park access by type in relation to trajectories of gentrification in Seattle from 1990 to 2010. The dissertation includes 5 Chapters. The first chapter provides an overview of the literature that motivated this research. The second, third and fourth chapters are research papers...

Flow-Solute : A Tool for Exploring the Effects of Nitrogen Management in Alternative Future Scenarios

Creator:: Wentworth, Andrew Michael
Abstract:: Surface water quality is a growing concern in the Willamette River Basin and elsewhere. The region's growing population is dependent on the availability of clean water for drinking water, irrigation, wastewater dilution, and wildlife habitat. Watershed management to produce economic goods and environmental services requires an understanding of basic hydrologic...
