Using GIS to illustrate the geospatial and socio-ecological intersection between climate change, energy production, and sustainable fisheries management in Oregon

Creator:: Cohn, Leanne A.
Abstract:: There could be a geospatial and socio-ecological intersection between climate change, energy production, and sustainable fisheries management in the United States. Marine renewable energy generation efforts are currently being planned, studied, and initially implemented in the country as a response to climate change. The Bureau of Ocean Energy Management is...

A method for remotely monitoring glaciers with regional application to the Pacific Northwest

Creator:: Medley, Brooke
Abstract:: An integrative method for monitoring glacier geometry change and mass balance is presented and applied to the Pacific Northwest, USA. Acting as a baseline for interpretation of future changes in glacier size and shape, we first derive a new inventory of regional glacier cover using remotely sensed data. To investigate...

Reactive polyphenols and dissolved nutrients in a nitrogen-limited headwater catchment, western Cascades, Oregon, USA

Creator:: Rasmussen, Janet K.
Abstract:: In undisturbed N-limited forested catchments, DON may represent over 90% of the total N lost in streams. Some ecologists have suggested that plant-derived reactive polyphenols may be responsible for DON binding and transport because polyphenol-protein complexes are known to precipitate out of solution, bind to mineral surfaces or organic matter...

Environmental Magnetism as a Proxy for Heavy Metal Concentrations at Formosa Mine Superfund Site

Creator:: Upton, Tullia L.
Abstract:: Environmental magnetic techniques have been used to discriminate sources of sediments from a variety of natural and anthropogenic sources. In many studies, magnetic properties such as susceptibility, have served as a proxy for heavy metal concentrations. In these cases, there tends to be enhancement of magnetic minerals. The study presented...

Multi-Centennial Response of ENSO Under Varying Atmospheric CO2

Creator:: Alder, Jay R.
Abstract:: The El Niño/Southern Oscillation (ENSO) affects millions of people via global teleconnections in the form of drought and torrential rainfall that impact agriculture and food production in many countries. Yet how ENSO will respond to a warming world is uncertain and a greatly debated topic. The Intergovernmental Panel on Climate...

Assessing the Role of Snow Cover for Regenerating Forests over Post-wildfire Landscapes in the Pacific Northwest

Creator:: Wilson, Andy C.
Abstract:: Forested, mountain landscapes in the Pacific Northwest (PNW) are changing at an unprecedented rate, largely due to shifts in the regional climate regime. Documented climatic trends across the PNW include increasing wildfire frequency and intensity and an increasingly ephemeral snowpack, especially at moderate elevations. One relationship that has yet to...

The influence of biophysical feedbacks and species interactions on grass invasions and coastal dune morphology in the Pacific Northwest, USA

Creator:: Zarnetske, Phoebe Lehmann
Abstract:: Biological invasions provide a unique opportunity to study the mechanisms that regulate community composition and ecosystem function. Invasive species that are also ecosystem engineers can substantially alter physical features in an environment, and this can lead to cascading effects on the biological community. Aquatic-terrestrial interface ecosystems are excellent systems to...

Life History Trade-offs: The Effects of Habitat Selection on Columbian Black-tailed Deer Survival in Oregon

Creator:: Clark, Jessica S.
Abstract:: The assessment of habitat quality for wild populations requires evaluation of vital rates associated with the use of that habitat. Factors associated with bottom-up (forage) or top-down (predation) regulation and the relative contribution of these processes on ungulate populations are difficult to quantify, especially for a cryptic, but widely distributed...

Post-harvest establishment influences ANPP, soil C and DOC export in complex mountainous terrain

Creator:: Peterson, Fox S.
Abstract:: The link between aboveground net primary productivity (ANPP) and resource gradients generated by complex terrain (solar radiation, nutrients, and moisture) has been established in the literature. Belowground ecosystem stocks and functions, such as soil organic carbon (SOC), dissolved organic carbon (DOC), and belowground productivity have also been related to the...

Landsat-based monitoring of annual wetland change in the main-stem Willamette River floodplain of Oregon, USA from 1972 to 2012

Creator:: Fickas, Kate C.
Abstract:: Despite holding substantial ecological value, wetlands in the United States have experienced a significant decline in both area and function over the past century with the majority of freshwater wetland loss attributed to agricultural conversion. Agriculture is the second largest industry in the State of Oregon and the State places...
