Nuclear and chloroplast diversity of Pacific Northwest wheat (Triticum aestivum) breeding germplasm

Creator:: Edwards, Melanie Love
Abstract:: Wheat breeders must effectively maintain and manage existing genetic diversity in order to continue the development of superior genotypes. It is therefore fundamental that the genetic relationships and diversity within the germplasm pools be thoroughly characterized and understood. Recently, DNA-based markers have provided powerful tools for genetic diversity analysis. This...

Building an electric antipredator fence [2002]

Creator:: Oregon State University. Extension Service, Washington State University. Extension, University of Idaho. Extension, United States. Department of Agriculture, Allen, Nancy, and Pacific Northwest Cooperative Extension
Abstract:: Two factors have led to curtailment of some lethal methods of combating sheep predators and limit the use of others: changes in public attitudes and more restrictive state and federal regulations. Ranchers now use more nonlethal methods for reducing losses of sheep to predator attack. Electric fence tests in Oregon...

The influence of canopy structure and epiphytes on the hydrology of Douglas-fir forests

Creator:: Pypker, Thomas G.
Abstract:: Canopy structure has a significant impact on the canopy hydrology of Douglas-fir forests in the Pacific Northwest (PNW). Whole canopy rainfall interception was measured for young Douglas-fir forest and compared to an old-growth Douglas-fir forest. The old-growth forest had significantly greater canopy water storage capacity (5) and direct throughfall fraction...

Changes in grain quality and grain protein composition of winter wheat cultivars under different levels of soil nitrogen and water stress

Creator:: Saint Pierre, Carolina
Abstract:: Hard white winter (HVVW) wheat cultivars must have superior protein quality and consistent processing quality to be successful in the Asian market. New cultivars and management strategies are needed to produce HVVW grain for both bread and noodle applications from diverse environments in the US Pacific Northwest (PNW). This study...

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...

Production and costs of cut-to-length thinning : experience from the Willamette Young Stand Project

Creator:: Kellogg, L. D. (Loren D.), Spong, Ben, and Oregon State University. Forest Research Laboratory
Abstract:: Young Douglas-fir stands were commercially thinned to achieve vegetation- and wildlife-related objectives. Harvesting and forwarding production and costs were compared among three mechanized thinning treatments: light thin [(115 residual trees per acre (tpa)], light thin with 0.5-ac openings (92 residual tpa), and heavy thin (53 residual tpa). The sites were...

Potential carbon storage at the landscape scale in the Pacific Northwest, U.S.A.

Creator:: Smithwick, Erica Ann Hoffa
Abstract:: Estimates of potential carbon (C) storage can be used to constrain predictions of future carbon sequestration and to understand the degree to which disturbances, both natural aid anthropogenic, affect C storage. An upper bound on C storage in the Pacific Northwest (PNW) of the United States was estimated using field...

Simulation of Water and Energy Fluxes in an Old-Growth Seasonal Temperate Rain Forest Using the Simultaneous Heat and Water (SHAW) Model

Creator:: Link, Timothy E., Flerchinger, Gerald N., Unsworth, Mike, and Marks, Danny
Abstract:: In the Pacific Northwest (PNW), concern about the impacts of climate and land cover change on water resources and flood-generating processes emphasizes the need for a mechanistic understanding of the interactions between forest canopies and hydrologic processes. Detailed measurements during the 1999 and 2000 hydrologic years were used to modify...

Bioindication of air quality in forests of northern and central California using epiphytic macrolichen communities

Creator:: Jovan, Sarah
Abstract:: The unifying purpose of this dissertation was to describe, model, and map relationships between epiphvtic macrolichen communities and air quality in Ibrests of northern and central California. First, multivariate analyses were used to subdivide the large study area into three model areas with similar climate, topography, and lichen communities: the...

Growth, Seed Yield, and Oil Production of Camelina sativa Grown Under Two Irrigation Rates from a Spring Seeding, and of Multiple Cultivars Seeded on Multiple Dates in the Fall, in the Klamath Basin, 2007- 08

Creator:: Roseberg, Richard J., Shuck, Rachel A., and Oregon State University. Klamath Basin Research and Extension Center
Abstract:: The recent increase in energy prices and political instability in the Middle East has sparked renewed interest in alternative energy sources and technologies both locally and nationally. Biodiesel is an appealing transportation fuel source for many reasons: it readily substitutes for petroleum diesel, it tends to burn cleaner with fewer...
