Responses of Pacific Northwest prairies to soil nutrient manipulations : implications for restoration of Castilleja levisecta and control of invasive species

Creator:: Lawrence, Caitlin E.
Abstract:: Pacific Northwest prairies have become significantly reduced in extent, and in the Willamette Valley of Oregon, less than one percent of native upland prairies remain. Many species have been impacted by this extreme loss of habitat, including Castilleja levisecta (golden paintbrush), a threatened hemiparasitic forb species endemic to the Pacific...

The distribution and partitioning of dissolved organic matter off the Oregon Coast : a first look

Creator:: Hill, Jon K.
Abstract:: The purpose of this thesis is to provide a first look at the spatial and temporal distributions of dissolved organic material (DOM) off the Oregon coast of North America. While this paper is not a comprehensive examination of these distributions, several patterns are identified as promising candidates for continued research....

Floating Offshore Wind Array Systems Optimization off the US West Coast using an Extended Pattern Search Algorithm

Creator:: Forinash, Caitlin P.
Abstract:: The large wind resource off the United States West Coast has the potential to generate wind power for millions of homes, yet the high cost of energy for offshore wind power compared to traditional sources has slowed the development of offshore wind farms in the US. The four studies presented...

Influence of cover crop residue management on soil moisture, vine growth, and productivity in a pre-production vineyard in the Willamette Valley

Creator:: Curtis, Morgan A.
Abstract:: The use of cover crops in young vineyards is not widely accepted in the Pacific Northwest due to concerns of water and nutrient competition between the cover crop and vines. The last 2 years of a 4-year study started in 2009 are reported here. The study evaluated the use of...

An evaluation of the invasion potential of Kochia prostrata (forage kochia) in southwestern Idaho, USA

Creator:: Gray, Erin C.
Abstract:: Purposeful introductions of exotic species for rehabilitation efforts following wildfire are common on rangelands in the western U.S., though potential ecological impacts of introduced species in novel environments are often poorly understood. One such introduced species, Kochia prostrata (L.) Schrad (forage kochia) has been seeded on over 200,000 ha throughout...

Evaluating the Effects of Alleyway Management on the Performance of Dry-Farmed Pinot noir Grown in Different Soils

Creator:: Lange, Mathew
Abstract:: Vineyards in Oregon’s Willamette Valley are predominately planted to perennial grass cover in the alleyways of vineyards. This grass cover is grown to increase worker and equipment traction, as well as reduce erosion and manage vine vegetative vigor. However, with increasing frequencies of drought and warming temperatures, the use of...

Effects of cover crop and vineyard floor management on young vine growth, soil moisture, and weeds in an establishing vineyard in the Willamette Valley of Oregon

Creator:: Fredrikson, Levi
Abstract:: Five vineyard floor management treatments were evaluated in a young vineyard in western Oregon to better understand the effects on vine growth and nutrition, soil moisture dynamics, and weed control during 2009 and 2010. Treatments included two mulched treatments where mowed alleyway residue was transferred in-row at rates of 1x...

Factors limiting the distribution of the sensitive lichen Usnea longissima in the Oregon Coast Range : habitat or dispersal?

Creator:: Keon, Dylan B.
Abstract:: The sensitive lichen Usnea longissima Ach., formerly a fairly common circumboreal species, has been extirpated from much of its range (e.g., Eastern Europe). Although the U.S. Pacific Northwest (PNW) remains a relative stronghold for the species, U longissima faces increasing pressure in the region from habitat loss, air pollution, and...

Facilitating plant-parasitic nematode management decisions for Washington Vitis vinifera growers : determining the spatial distribution of plant-parasitic nematodes and the host status of Vitis spp. to Meloidogyne hapla

Creator:: Howland, Amanda D.
Abstract:: A major constraint to the production of self-rooted wine grapes (Vitis vinifera) in eastern Washington is plant-parasitic nematodes. Plant-parasitic nematodes can impact grape productivity by limiting water and nutrient uptake, educing physiological changes, and extracting plant nutrients from roots, thereby reducing root biomass, plant vigor, and yield. The most commonly...

"No pain, no fear, no regrets": views of a good death

Creator:: Amberwood, Lee J.
Abstract:: Substantial research has shown deficits in the quality of end-of-life care in the U.S. In response to evidence of these deficits, efforts have been made to improve quality of end-of-life care. One approach has been to ask the question, "What is a good death?" Data on views of a good...
