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...

Fabrication of a flexible glucose sensing catheter for human implantation

Creator:: Matthews, David J.
Abstract:: Flexible electronics processing techniques were applied to integrate a glucose sensor with a hormone-delivery catheter in order to create a cheap and minimally invasive method for patients with type 1 diabetes to continually monitor and control their blood sugar levels. Ultimately, this work intends to move toward the development of...

Developing a plan for the national coordination of geospatial technology education : a community college perspective

Creator:: Sullivan, Deidre E.
Abstract:: Geospatial technology is a rapidly growing and changing field. The term geospatial technology (GST) refers to geographical information systems (GIS), global positioning systems (GPS), and remote sensing (RS), all emerging technologies that assist the user in the collection, analysis, and interpretation of spatial data. The speed at which new fields...

Spatiotemporal Assessment of Crop Histories in the Pacific Northwest

Creator:: Kumbhakar, Ishika G.
Abstract:: The cultivated potato (Solanum tuberosum) is one of the most important food crops in the United States, as well as globally. As demand rises, growers in the Pacific Northwest are revisiting their crop management strategies to determine whether there are additional ways to enhance crop productivity while managing plant and...

Multiscale assessment of thermal patterns and the distribution of chinook salmon in the John Day River Basin, Oregon

Creator:: Torgersen, Christian E.
Abstract:: This study examined the distribution and behavior of adult spring chinook salmon (Oncorhynchus tshawytscha) related to patterns of stream temperature and physical habitat at channel unit, reach, and basin-wide spatial scales in both a wilderness stream and a disturbed stream in the John Day River basin in northeastern Oregon. Thermal...

An Integrated Approach to Gauge the Effects of Global Climate Change on Headwater Stream Ecosystems

Creator:: Bury, Gwendolynn W.
Abstract:: Climate change is predicted to affect ecosystems, including systems already stressed by human impacts. One ecosystem that is already highly impacted by human land use is the cold headwater stream system of the Pacific Northwest. One method of assessing the function of an ecosystem is by using an indicator species....

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...

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...

Effects of spatial scale and heterogeneity on avian occupancy dynamics and population trends in forested mountain landscapes

Creator:: Frey, Sarah J. K.
Abstract:: Population trends and patterns in species distributions are the major currencies used to examine responses by biodiversity to changing environments. Effective conservation recommendations require that models of both distribution dynamics and population trends accurately reflect reality. However, identification of the appropriate temporal and spatial scales of animal response, and then...

Spatio-temporal Patterns and Ecological Drivers of Harbor Porpoise (Phocoena phocoena) off the Central Oregon Coast, USA

Creator:: Holdman, Amanda
Abstract:: The marine environment is under increasing pressure from human activities worldwide, particularly in coastal waters, creating a need to better understand fine-scale distributions of highly mobile species that occur in the area, as they are frequently most threatened. Harbor porpoise (Phocoena phocoena) occur frequently in Oregon’s nearshore habitat, but due...
