PURPOSE: To determine physical, plankton and nutrient/chemical conditions over the continental margin for climate change studies in NE Pacific. In particular, to make CTD and CTD/rosette and net tow stations along 5 lines (off Newport, Heceta Head, Coos Bay, the Rogue River and Crescent City, OR, to deploy drifters at...
Concerns about the extent to which major Pacific Northwest floods over the last decade might have been exacerbated by logging have heightened the need for a better scientific understanding of the role of forest maturity on snow accumulation and melt. To address this need, a multi-scale field and modeling study...
This paper describes the application of aerial photography and GIS technology to develop flexible and transferable methods for multi-spatial scale characterization and analysis of riparian corridors. Relationships between structural attributes of riparian corridors and indicators of stream ecological conditions are not well established. As part of a research project focused...
This report summarizes accomplishments of the McKenzie River Focus Watershed Council (MWC) in the areas of coordination and administration during Fiscal Year 2000. Coordination and administration consist of prioritization and planning for projects; project management and implementation; procurement of funding for long-term support of the Council; and watershed education/outreach program...
Due to its frequent use in agriculture and its frequent detection in surface water,
atrazine was chosen as a model compound to study the treatment capability of a surface flow wetland used to remediate irrigation runoff at a container nursery near Portland, Oregon. Further evaluation of treatment of atrazine was...
Deforestation, intensive agriculture and chemical use all can cause long-lastingn negative impacts on soil health. With all the vital functions that soils perform and the potential for further soil degradation, it is important that standards of soil quality or soil health be implemented. Soil aggregation is considered to be a...
Northwest cherry cultivars including Prunus avium 'Bing', Prunus avium 'Rainier', Prunus avium 'Royal Anne' and Prunus cerasus 'Montmorency' were separated into epidermal tissue, flesh and pit and cryogenically milled with liquid nitrogen. These samples as well as whole samples from each variety were extracted with acetone followed by a chloroform...
Critics of higher education urge educators to transform their institutions so as to align them with the needs of the twenty-first-century learner. However, colleges desiring to survive in a rapidly changing external environment often discover they must first find a way to make
fundamental changes in their institutional culture. Some...
An organisms' genotype may not be reflected in its phenotype. For example, epistasis - the interaction of non-allelic genes can cause deviations from expected phenotypic ratios. The epistatic interaction between the hooded (Kap) and short-awned (lks2) loci in barley (Hordeum vulgare) precludes the localization of the Kap locus, based on...
Chlamydiae are obligate intracellular bacterial pathogens with a unique biphasic life cycle that consists of an infectious but non-dividing form, called elementary bodies (EB), and a noninfectious but metabolically active form, called reticulate bodies (RB). Chlamydia has an unusual process of cell division of which still remains uncharacterized subject matter;...
