Grain is produced on upwards of 100,000 acres in the Klamath Basin including nearly 50,000 acres within the Klamath Reclamation Project. Susceptibility to late spring frost has historically limited winter cereal production and spring cereals have accounted for the majority of production. Klamath Basin Research & Extension Center (KBREC) cereal...

Since its inception in 1985, the Tri-State variety development program has primarily focused on the development of processing and dual-purpose (process and fresh) russets. Recent breeding efforts have focused more on improving genetic resistance to various pests and diseases as a means of lowering production costs. During the past decade,...
This issue is packed with new information from various research trials conducted here in Oregon, whether it is from vineyard plots, the wine lab, or the growth chamber, results are likely to have impact on vineyard and winery production here in Oregon. James Osborne, Enology Extension Specialist, opens this month’s...
The Columbia River Gillnetter is the pilot of the Lower Columbia River commercial fishing industry, keeping fishermen and the public in touch with today's important issues.
Crops were grown at the experimental farms using accepted cultural practices (within the limits of experimentation) or trials were conducted on growers' fields. Most experiments were designed as randomized complete blocks with three to five replications. Herbicide treatments were applied uniformly with CO₂ precision plot sprayers. Unless otherwise indicated, preplant...
Many high school teachers are prohibited from interacting with students in social media sites despite the fact that the majority of teenagers actively use them. The first opportunity most students have to interact with instructors in an online environment is in higher education. University and college librarians can take the...

Sclerotinia sclerotiorum (causal agent of white mold) can cause serious economic losses in snap bean production as well as many other crops. Spores are produced in apothecia (mushroom-like structures) that develop from over-wintering sclerotia in the soil. Sclerotia are long-lived, durable hyphal survival structures produced by the fungus and they...
The present study employs a normalized restricted quadratic profit function approach to estimate lumber and plywood supply and Marshallian factor demand elasticities for four region-product combinations in Oregon for the period 1970-2010. The four log demand functions will be employed as the "demand side" of the log market model of...
Because of their new independent status as young adults, undergraduate college students are at a crucial point in the development of significant health behaviors, especially as related to physical activity. Unfortunately, in the United States, there is clear evidence that the lifestyle choices college students make are not always healthy...
The growth of a plant’s root system is essential for its survival. Preliminary observations suggest that a protein complex called the exocyst may play a role in the development of the root system by facilitating the growth of roots and root hairs. Previous work discovered a protein that potentially interacts...
Declines in glacier area and volume are widespread. These changes will have important hydrologic consequences since glaciers store tremendous amounts of fresh water and buffer seasonally low flows in many densely populated regions. In this thesis I focus on a region that is hydrologically vulnerable to glacier change, namely the...
Question: Most results of restoration efforts are species-specific and/or site-specific and therefore are not general enough to be easily applied to other species and other sites. Our research addresses the issue of species-specific results by investigating the feasibility of using plant traits instead of taxonomic species to characterize species responses...
Native prairies, which once dominated the landscape of the Willamette Valley, are considered among the rarest of Oregon's ecosystems and are in critical need of conservation. One of the largest remaining parcels of native upland prairie, Butterfly Meadows (Benton County), is being invaded by Brachypodium sylvaticum (false brome). This site...
This white paper outlines interim guidance for development of Oregon Department of Fish and Wildlife habitat mitigation recommendations associated with renewable energy development and associated infrastructure or other landscape scale industrial-commercial developments in greater sage-grouse habitat in Oregon. This guidance is interim until empirical data are available that quantify the...
Prior to settlement in the 19th century, greater sage-grouse (Centrocercus urophasianus; hereafter referred to as ‘sage-grouse’) inhabited 13 western States and three Canadian provinces, and their potential habitat covered over 1,200,483 square kilometers (km) (463,509 square miles (mi)). Sage-grouse have declined across their range due to a variety of causes...
Objective: To examine the associations between the 2008 economic collapse in Iceland and smoking behaviour at the national and individual levels.
Design: A population-based, prospective cohort study based on a mail survey (Health and Wellbeing in Iceland) assessed in 2007 and 2009.
Setting: National mail survey.
Participants: Representative cohort (n=3755)...
Flow and temperature are strongly linked environmental factors driving ecosystem processes in streams. Stream temperature maxima (T [subscript max_w]) and stream flow minima (Q[subscript min]) can create periods of stress for aquatic organisms. In mountainous areas, such as western North America, recent shifts toward an earlier spring peak flow and...
We present the geomorphology of the Eastern Samoa Volcanic Province, covering 28,446 km², and depths ranging from ~50-4000 m. A new compilation of available multibeam data reveals 51 previously undocumented seamounts, and delineates major submarine rift zones, eruptive centers, and volcanic plateaus. Moving from a regional to local scale, and...
Density-independent and density-dependent variables both affect the spatial distributions of species. However, their effects are often separately addressed using different analytical techniques. We apply a spatially explicit regression framework that incorporates localized, interactive and threshold effects of both density-independent (water temperature) and density-dependent (population abundance) variables, to study the spatial...
All major web mapping services use the web Mercator projection. This is a poor choice for maps of the entire globe or areas of the size of continents or larger countries because the Mercator projection shows medium and higher latitudes with extreme areal distortion and provides an erroneous impression of...
Concurrent satellite-measured chlorophyll (CHL), sea surface temperature (SST), sea level anomaly (SLA) and model-derived wind vectors from the 13+ year SeaWiFS period September 1997 – December 2010 quantify time and space patterns of phytoplankton variability and its links to physical forcing in the Pacific Ocean. The CHL fields are a...
