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...

Synthesis and assembly of Fucus zygote cell walls with an emphasis on alignate and fucans

Creator:: Doubet, Scott
Abstract:: Fucus distichus L. Powell zygotes were used to investigate cell wall synthesis and development and to construct a model of cell wall structure. Alginate synthesis was investigated. Zygotes were cultured in seawater containing ¹⁴C-bicarbonate. Alginate represented 12%, 37%, and 1.7% of the label recovered from whole zygotes, wall, and cytoplasm,...

A potato growth and production model

Creator:: Apple, Jeanne Debons
Abstract:: A potato plant growth and production model is developed with the objectives of analyzing management alternatives and exploring the nature of the early dying syndrome. The geographic area of focus was the centerpivot irrigated circles of Oregon's Columbia Basin. A problem analysis of the potato production system of this area,...

Lichen response to the environment and forest structure in the western Cascades of Oregon

Creator:: Martin, Erin P.
Abstract:: Lichens are an important part of the biota in western Oregon forests, where they perform valuable ecological roles and contribute significantly to biodiversity. Lichens in western Oregon are threatened by a number of factors including air pollution and land use practices. If we wish to maintain the persistence of lichens...

Forecasting Pseudocercosporella herpotrichoides foot rot of winter wheat

Creator:: Grybauskas, Arvydas P.
Abstract:: The use of fungicides for the control of foot rot of winter wheat, caused by Pseudocercosporella herpotrichoides (Fron) Dei., requires a forecast of disease risk to optimize this management practice ecologically and economically. Foot rot occurs in both the mild, wet (100+ cm, ppt./year) annual cropped areas in western Oregon,...

Phytophthora species and riparian alder tree damage in western Oregon

Creator:: Sims, Laura L.
Abstract:: The genus Phytophthora contains some of the most destructive pathogens of forest trees, including the most destructive pathogen of alder in recent times, Phytophthora alni. Alder trees were reported to be suffering from canopy dieback in riparian ecosystems in western Oregon, which prompted a survey of alder health and monitoring...

Carbonyl Sulfide Inhibition of CO Dehydrogenase from Rhodospirillum rubrum

Creator:: Hyman, Michael R., Ensign, Scott A., Arp, Daniel J., and Ludden, Paul W.
Abstract:: Carbonyl sulfide (COS) has been investigated as a rapid-equilibrium inhibitor of CO oxidation by the CO dehydrogenase purified from Rhodospirillum rubrum. The kinetic evidence suggests that the inhibition by COS is largely competitive versus CO (Ki = 2.3 pM) and uncompetitive versus methylviologen as electron acceptor (Ki = 15.8 pM)....

The Personal Sequence Database: a suite of tools to create and maintain web-accessible sequence databases

Creator:: Givan, Scott A., Sullivan, Christopher M., and Carrington, James C.
Abstract:: Background: Large molecular sequence databases are fundamental resources for modern bioscientists. Whether for project-specific purposes or sharing data with colleagues, it is often advantageous to maintain smaller sequence databases. However, this is usually not an easy task for the average bench scientist. Results: We present the Personal Sequence Database (PSD),...

Annual cycles of ecological disturbance and recovery underlying the subarctic Atlantic spring plankton bloom

Creator:: Behrenfeld, Michael J., Doney, Scott C., Lima, Ivan, Boss, Emmanuel S., and Siegel, David A.
Abstract:: Satellite measurements allow global assessments of phytoplankton concentrations and, from observed temporal changes in biomass, direct access to net biomass accumulation rates (r). For the subarctic Atlantic basin, analysis of annual cycles in r reveals that initiation of the annual blooming phase does not occur in spring after stratification surpasses...
