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...

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...

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...

Giant otters (Pteronura brasiliensis) and humans in the lower Yasuní Basin, Ecuador : spacio-temporal activity patterns and their relevance for conservation

Creator:: Carrera-Ubidia, Paola M.
Abstract:: Giant otters (Pteronura brasiliensis) and humans in the Lower Yasuní Basin (Ecuador) have similar food and space requirements: they consume comparable arrays of fish species, and they use similar aquatic and terrestrial habitats. Resource partitioning could facilitate coexistence by allowing each species exclusive access to some resources. My research examines...

Identification of economic, social, and policy factors influencing irrigation district participation in water transactions in the Deschutes Basin

Creator:: Whitman, Cally A.
Abstract:: Surface water in the Deschutes Basin of central Oregon has been largely over allocated since the early 1900s. Therefore, rapid population growth and urban demand for water in the upper Basin lead to an increased reliance on groundwater in the last three decades. The Oregon Department of Water Resources (OWRD)...

Thirty-five years of forest succession in southwest Oregon : vegetation response to three distinct logging treatments

Creator:: Arthur, Aaron Stone
Abstract:: This study examined patterns and controls on 35-years of forest succession following logging in the 236 ha South Umpqua Experimental Forest within the Umpqua National Forest in southwestern Oregon. Prior to logging, the overstory in all three watersheds (~50% cover) was composed of Douglas-fir (30-40% cover), grand fir (2 to...

Distribution and abundance of coastal fish and macro-invertebrates in the Galapagos Islands

Creator:: Figueroa, Diego
Abstract:: The Galapagos Islands, located off the coast of Ecuador, have a spatially diverse marine environment suitable for a variety of species with different climatic requirements. A year-long inventory program was carried out in 2000-2001 to provide baseline data on the abundances and distribution of coastal fish and macro-invertebrates. The purposes...

Stormwater Solutions for Improving Water Quality: Supporting the Development of the Amazon Creek Initiative

Creator:: Larson, Kristen M.
Abstract:: The Long Tom Watershed Council (LTWC) is a non-profit organization in Eugene, Oregon that serves to protect and enhance watershed health in the Long Tom River Basin. The Amazon Creek Initiative was launched by the LTWC in 2011 as Oregon’s newest Pesticide Stewardship Partner. Goals of the initiative are to...

Reviving Whychus Creek: Averting Collisions between the Endangered Species Act and Agricultural Water Use through Proactive Streamflow Restoration

Creator:: Dengel, Jeff
Abstract:: In the wake of policies catalyzing settlement through agrarian-based land ‘improvement’, private property rights absorbed water resources through Western water law. Consequently, these dominant user regimes and the doctrine of prior appropriation allocated nearly 80 percent of freshwater resources to agricultural use. Following enactment of the Endangered Species Act (ESA)...
