Investigating the ecological role of cell signaling in free-living marine heterotrophic protists

Creator:: Hartz, Aaron J.
Abstract:: Phagotrophic protists are major consumers of microbial biomass in aquatic ecosystems. However, biochemical mechanisms underlying prey recognition and phagocytosis by protists are not well understood. We investigated the potential roles of cell signaling mechanisms in chemosensory response to prey, and in capture of prey cells, by a marine ciliate (Uronema...

The Influence of grazing on active γ-Proteobacteria cells

Creator:: Wilson, Michelle Juliette
Abstract:: By identifying the relationships between abundance and metabolic activity in a bacterial community, we advance our knowledge of the marine carbon cycle. In the present study, our goal was to examine the role of protist grazing on the metabolic activity of γ- Proteobacteria in the upwelling system off the Oregon...

Gender Disparity in American Literary Fiction: Women Writing the Female Experience of Romantic Relationships in Short Fiction and a Collection of Original Short Stories

Creator:: Dealy, Rebecca Corinne
Abstract:: Unpublished female authors of American short fiction face many prejudices in fiction publishing, submission, and reviewing. These prejudices stem from the writer’s position in a gender-unequal society. Feminist fiction provides dimensional, diverse female characters in relationships where previous fiction had offered only stereotypes whose role was to support and reflect...

Resilience in Collaborative Forest Landscape Restoration: The Lakeview Stewardship Group’s Response to the Barry Point Fire

Creator:: Spaeth, Andrew D.
Abstract:: Congress created the Collaborative Forest Landscape Restoration Program (CFLRP) in 2009 with the passage of the Forest Landscape Restoration Act (Omnibus Public Lands Management Act of 2009 Title IV). The purpose of the CFLRP legislation is to implement forest restoration work on national forest lands through a competitive grant program....

Soil biological, chemical, and physical dynamics during transition to non-thermal residue grass-seed management systems

Creator:: Barry, Amanda Nell
Abstract:: Legislation to reduce the annual limit of field burning in Oregon has led to increased study of alternative non-thermal grass-seed management methods. Of these methods, non-thermal residue management, in combination with crop rotations and different tillage practices, offer potential to equal or exceed crop production of conventional thermal production systems....

Phosphorus physiology and environmental forcing of oceanic cyanobacteria, primarily Trichodesmium spp.

Creator:: White, Angelicque E.
Abstract:: The biological transformation of dinitrogen gas (N2) into combined forms(termed N2 fixation) by certain genera of oceanic cyanobacteria represents the largest incoming flux of nitrogen to the global ocean. As such, biological nitrogen fixation plays a significant role in the regulation of oceanic productivity and the export of carbon and...

Quantification of Copper Speciation in Pulp and Paper Wastewater and Implications for the Biotic Ligand Model

Creator:: Mitzel, Joseph M.
Abstract:: The purpose of this research was to measure the copper-binding behavior of Dissolved Organic Matter (DOM) contained in Pulp and Paper (P&P) wastewater effluent and evaluate the Biotic Ligand Model’s (BLM) ability to quantify copper speciation in P&P influenced waters. A copper ion selective electrode was used to measure copper...

Created Snag Dynamics and Influence on Cavity-nesting Bird Communities over 25 years in Western Oregon

Creator:: Barry, Amy Marie
Abstract:: Snags provide critical habitat for nearly one-third of wildlife species in forests of the Pacific Northwest, so historic declines in snags are thought to have had a strong impact on biodiversity. Resource managers often create snags to mitigate the scarcity of snags within managed forests, but information regarding the function...

Distribution, habitat associations, and conservation status of Pacific fisher (Pekania pennanti) in Oregon.

Creator:: Barry, Brent R.
Abstract:: Fishers (Pekania pennanti) are medium sized mustelids endemic to North America. Two fisher populations persist in Oregon: an indigenous population in southwestern Oregon, and a reintroduced population in the southern Cascade Mountains. Despite candidacy for listing under the Endangered Species Act, current information on fisher populations in Oregon is scarce....
