The root-lesion nematode Pratylenchus (hornet is one of the most important pests restricting productivity of wheat in the Pacific Northwest (PNW). It is laborious and difficult to use microscopy to count and identify the nematodes in soils. A SYBR Green I-based real-time polymerase chain reaction (PCR) assay was developed to...
Heterodera avenae and H. filipjevi are economically important cyst nematodes that restrict production of cereal crops in the Pacific Northwest United States and elsewhere in the world. Identification of these two species is critical for recommending and implementing effective management practices. Primers were designed from the internal transcribed spacer (ITS)...
Pratylenchus neglectus is one of the most widespread and economically important nematodes that invades plant roots and restricts wheat productivity in the Pacific Northwest. It is challenging to quantify P neglectus using microscopic methods for studies that require large-scale sampling, such as assessment of rotation crops, wheat cultivars, and other...
In the fall of 2005, I studied abroad in Athens, Greece for one term. This is retelling of experiences that I had, written in the style of my memories. While I was in Greece, I kept an electronic diary, a picture diary, and a scrapbook to keep my memories vivid...
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...

The purpose of this study was to compare the delinquent behavior, psychological
health, and emotional wellbeing of maltreated and nonmaltreated adolescents in a
chemical dependency treatment program. Data were collected over a seven year period
from intake interviews and Minnesota Multiphasic Personality Inventory (MMPI) scores
of 522 adolescent patients at...
Grapevine red blotch disease (GRBD) is caused by Grapevine Red Blotch Virus, a virus in the Geminiviridae family. Observable symptoms can manifest in red cultivars, such as leaf blades that are partially to fully red, red veins, and different combinations of the two. Previous research has shown evidence of reduced...
Mule deer (Odocoileus hemionus hemionus) and Rocky Mountain elk (Cervus canadensis nelsoni; hereafter elk) populations in northeast Oregon have declined in the past 10 to 20 years. Concurrent with these declines, cougar (Puma concolor) populations have apparently increased, leading to speculation that predation by cougars may be responsible for declining...
Parkway trees, trees within a designated landscape and often owned by the city, can be an asset to any municipality but also have the potential to be a liability if improperly managed. The many benefits of parkway trees include increasing property and retail value, providing natural shade and windbreaks that...
The lack of first-hand experience or knowledge about
farming in the general population of the United States is a
concern among scientists as many current environmental
issues are strongly linked to agriculture. Developing
agricultural literacy and an appreciation for our dependance
on limited resources is important for preparing future
generations...
