Measuring Combine Facilitated Transport of Italian Ryegrass [Lolium perenne L. ssp. multiflorum (Lam.) Husnot] Seed During Wheat Harvest and Preventing the Distribution of Italian Ryegrass Seed During Harvest by Removal or Destruction of Chaff

Creator:: Roerig, Kyle C.
Abstract:: Italian ryegrass [Lolium perenne L. ssp. multiflorum (Lam.) Husnot] resistant to multiple herbicide sites of action continues to limit winter wheat production in western Oregon. In addition to impacting wheat production, multiple resistant Italian ryegrass may threaten the market for annual ryegrass seed for cover crops if wheat fields with...

Using stable isotopes and visual gut examination to determine the diet composition of Pterostichus melanarius (Coleoptera: Carabidae) in western Oregon vegetable row crops

Creator:: Moulton, Laurel A.
Abstract:: The omnivorous ground beetle, Pterostichus melanarius Illager (Coleoptera: Carabidae), is a ubiquitous inhabitant of western Oregon crop land. Because it is often the most abundant ground beetle, and attains densities that could lead to serious impacts on its prey sources, I sought to understand the overall diet composition, and specifically...

Weeds With a Purpose: Interseeding Cover Crops into Sweet Corn in Western Oregon

Creator:: Donaldson, Andrew R.
Abstract:: Cover crop establishment in late-season crops, like sweet corn, may be difficult due to the relatively short operational window following crop harvest. In regions like western Oregon, where fall-precipitation can occur when the crop is still in the field, cover crops may not be able to be planted, due to...

Characterizing adaptive governance capacity : A case study of the Willamette River Basin

Creator:: Jones, Ingria
Abstract:: The Willamette River Basin supports 70% of Oregon’s population and contains the richest native fish fauna in the state, (Hulse, Gregory, & Baker, 2002). The Basin is facing changes that stress its water management regimes. Is the Basin’s water management regime able to adapt in the face of these changes?...

Structuring habitat to conserve ground beetles (Coleoptera: Carabidae) and reduce summer annual weeds in agroecosystems

Creator:: Green, Jessica M.
Abstract:: Weed management in sustainable farming systems often requires the integration of several different pest management techniques. Cultural, biological, and chemical pest control efforts can be utilized to contribute to the common goal of reducing weeds in vegetable row crop systems. This research addresses how common disturbances such as tillage and...

Some potential mechanisms for finely-tuned regulation of phospholipase C-β isozymes : studies of dimerization and phosphatidylinositol 3,4,5-trisphosphate activation

Creator:: Zhang, Yong
Abstract:: Phospholipase C-β (PLC-β) isozymes are key effectors in G protein-coupled signaling pathways. Prior research suggested that some isoforms of PLC-β may exist and function as dimers, but little is known about dimerization of PLC-β. Data from coimmunoprecipitation assays of differentially-tagged PLC-β constructs and sizeexclusion chromatography of native PLC-β support homodimerization...

Ascorbylation- the biological relevance of covalently bound ascorbic acid

Creator:: Kesinger, Nicholas G.
Abstract:: Ascorbic acid, or vitamin C, is well known as a co-factor for proline-hydroxylase and as an anti-oxidant. However, it is also capable of forming covalent bonds, particularly in the role of a nucleophile, henceforth termed 'ascorbylation'. The ascorbylation of electrophiles can occur under physiological conditions. Furthermore, there are a number...

Vegetation analysis and spatial visualization of a tidal salt marsh

Creator:: Buchner, Ed L.
Abstract:: Mitchell Marsh, a tidal salt marsh in the Salmon River Estuary, was diked in the early 1960s. Restoration of the marsh, which began in late 1978, consisted of partial dike removal. Several studies have been conducted in the marsh, addressing the status of the developing salt marsh plant communities. Species...

Early Math Enrollment in Washington State Community Colleges

Creator:: Harri, Ed J.
Abstract:: More than half of students in Washington state community colleges enroll in developmental mathematics, but a relatively small percentage of these students persist to the second year. Many students place into these courses and never enroll; others enroll at some point after the first academic term, even when faced with...

Role of Plc in the germination of Clostridium perfringens food poisoning isolate SM101

Creator:: Bond, Colton B.
Abstract:: Clostridium perfringens is the causative agent of gas gangrene and the 3rd most common cause of type A food borne disease in the United States. Critical to the pathogenicity of C. perfringens is the ability of this bacterium to produce highly resistant, metabolically dormant spores that can resume metabolic function...
