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...

Surface-Initiated Click-Ready Bioactive Polymer Coatings: Synthesis and Characterization

Creator:: Yu, Bonan
Abstract:: Protein adsorption on blood contacting medical devices usually causes fouling and failure, and may promote clotting and undesirable immune responses. Hydrophilic polymer coatings in a dense, pendent “brush” conformation can resist protein adsorption on the surface while increasing biocompatibility. Such coatings can also be used to immobilize a variety of...

Insights into an Invasive Jumping Earthworm: Assessing the Invasion Risk and Influence on Soil Organic Matter by Amynthas agrestis in Western Oregon

Creator:: Tucker Serniak, Linda F.
Abstract:: Increased globalization has greatly increased the ability for species to travel outside of their native range and reach all parts of the world. While most species do not have an impact in new habitats, a small percentage are able to establish a new population and spread, causing ecological damage and...

Characteristics of soil organic matter in two forest soils

Creator:: Crow, Susan E.
Abstract:: Soil organic matter (SOM) is the terrestrial biosphere's largest pool of organic carbon (C) and is an integral part of C cycling globally. Soil organic matter composition typically can be traced directly back to the type of detrital inputs; however, the stabilization of SOM results as a combination of chemical...

The imprint of coarse woody debris on soil biological and chemical properties in the western Oregon Cascades

Creator:: Spears, Julie D. H.
Abstract:: The abundance and spatial heterogeneity of coarse woody debris (CWD) on the forest floor is a prominent feature of Pacific Northwest (PNW) forest ecosystems. The effect of CWD on soil solution chemistry, nutrient cycling and availability, soil physical structure and formation of soil organic matter, however, remains unknown. Therefore, studies...

The fate of organic and inorganic nitrogen inputs in an old-growth forest of the central Oregon Cascade Range

Creator:: Holub, Scott M.
Abstract:: Forests in the Pacific Northwest receive very little nitrogen through atmospheric deposition and thus studying the nitrogen cycle in this region can provide insights into how the unpolluted nitrogen cycle functions. I examined the fate of organic nitrogen versus inorganic nitrogen and the effect of tamlins on N retention by...

An Oregonian Jarabe : Danza Folklórica and Mexicana Mothers

Creator:: Olvera, Monica L.
Abstract:: Acculturative stress can be associated with increased conflicts between Latino parents and adolescent youth, and have negative effects on Latino immigrant parents' psychosocial functioning and parenting practices. Yet, the potentially deleterious effects of acculturative stress on Latino immigrant parents' psychosocial functioning and parenting practices may be mitigated through positive acculturative...

Detrital Influences on Soil Carbon Stabilization in Wet Temperate Forest Soils

Creator:: Pierson, Derek N.
Abstract:: Soils, with their potential to store and stabilize carbon (C), are an essential resource for sustaining forest productivity, as well as for efforts to reduce atmospheric C concentrations. Protecting existing soil C and harnessing the sequestration potential of our soils require an improved understanding of the processes through which soil...

Spatial and temporal effects of atmospheric deposition, climate, and land management on forest nutrient cycling and biodiversity

Creator:: McDonnell, Todd C.
Abstract:: Emissions largely associated with the combustion of fossil fuels and agriculture has caused elevated atmospheric deposition of nitrogen (N) and sulfur (S) throughout much of the developed world. Increased atmospheric deposition of N and S can lead to soil and surface water acidification and affect forest soil nutrient supply. The...

Aquatic community responses to drought disturbance: experimental manipulations of top predator extinctions and stream drying

Creator:: Boersma, Kate S.
Abstract:: Although it is generally assumed that the intensifying abiotic environment is the primary effect of drought on aquatic organisms, drought-induced top predator extinctions may be an important underlying mechanism. I used manipulative experiments to disentangle the impacts of drying and top predator extinctions on arid-land aquatic invertebrate communities. I then...
