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 frosts has historically limited winter cereal production and spring cereals have accounted for the majority of production. Klamath Basin Research & Extension Center (KBREC) cereal...
Concerns were raised about loss of soil from wind erosion with the announcement in early 2010 that most Klamath Reclamation Project water users would receive a delayed and reduced rate of irrigation water during the 2010 growing season, with some areas potentially receiving no irrigation water for the entire season....
Euphorbia lagascae (Euphorbiaceae- ‘spurge family’) has been recognized as one of the more promising potential new industrial crops for the drier regions in the temperate zone
(Roseberg, 1996). In the late 1950s and early 1960s the USDA analyzed many plant species in search of novel chemical compounds. They first recognized...
Non-market valuation research has produced value estimates for over forty threatened and endangered (T&E) species, including mammals, fish, birds, and crustaceans. Increasingly Stated Preference Choice Experiments (SPCE) are utilized for valuation, as the format offers flexibility for policy analysis and may reduce certain types of response biases as compared to...
Incorporating catch or harvest rate information in repeated-choice recreation fishing demand models is challenging, since multiple sources of information may be available and detail on how harvest rates change within a season is often lacking. This paper develops a framework for evaluating which source(s) of information should be used to...
The crooked stems of some individuals of radiata pine (Pinus radiata D. Don) can hinder volume recovery and wood quality. To infer causes of crookedness and to learn how angle affects compression wood (CW) formation we studied 4+1-year old trees in southern Chile. Eight initially straight and 8 initially crooked...
As global climate changes over the next century, forest productivity is expected to change as well. Using PRISM climate and productivity data measured on a grid of 3356 plots, we developed a simultaneous autoregressive (SAR) model to estimate the impacts of climate change on potential productivity of Pacific Northwest (PNW)...
The purpose of this paper is to provide an overview of the current state of worldwide mobile usage; mobile technologies; libraries' use of mobile technologies including a review of library mobile catalog options, both vendor-supplied and in-house created; perspectives from current library leaders and innovators on the importance of incorporating...
Given the fundamental importance of xylem safety and efficiency for plant survival and fitness, it is not surprising that these are among the most commonly studied features of hydraulic architecture. However, much remains to be learned about the nature and universality of conflicts between hydraulic safety and efficiency. Although selection...
Genetic information for male and female hop accessions is limited, hampering
parental selection to maximize offspring productivity. Our objective
was to determine whether amplified fragment length polymorphism (AFLP)-derived genetic distance (GD[subscript mm]) estimates and coancestry estimates from
pedigrees (GS[subscript ped]) between parental pairs could be used to predict offspring
performance....
The coded wire tag (CWT) database contains detailed information on millions of Pacific salmon
Oncorhynchus spp. released from hatcheries or smolt traps and recovered in the north Pacific Ocean and its tributaries. I used this data set to examine the spatial and temporal variation in the marine distributions of 77...
The amounts of treated wood present at a wood recycling center in western Oregon were surveyed over a 10-year period. Treated wood was found at 106 of 112 inspections, but the levels never exceeded 2 percent of the volume present. The amount of treated wood averaged 0.15 percent of the...
In 2002, oxygen isotope ratios of water (H2
18O/H2
16O), dissolved barium, and salinity were
measured in surface waters around northern North America to identify freshwater sources and to
provide a large-scale background for interpretation of regional inputs and processes. Oxygen isotope
ratios showed that precipitation, river runoff, and sea...
Epidermal RNA samples from FVB/N mice treated with PAH standards and environmental PAH mixtures were harvested and purified using Trizol extraction and RNeasy mini prep kit purification. Epidermal RNA integrity was low (RIN mean 3.5), indicating significant RNA degradation and the need to modify handling, collection, and processing of skin...

During AY 2009/10 OSU Libraries’ Research and Innovative Services Department (RIS) conducted a pilot project on “environmental scanning.” One of our goals for the year is to develop a process to investigate emerging trends based on a topic and disseminate our findings. Initially we each scanned a segment of the...
We study the stability properties of, and the phase error present in, several higher order (in space) staggered finite difference schemes for Maxwell's equations coupled with a Debye or Lorentz polarization model. We present a novel expansion of the symbol of finite difference approximations, of arbitrary (even) order, of the...
In an effort to foster a collaborative approach to advancing the ocean energy industry, OWET convened the OWET 2010 Developersʼ Summit on September 27 and 28, 2010 in Portland, Oregon. The purpose of the Summit was to create an open dialogue among developers, utilities, and regulatory and policy leaders to...
Goals of this preliminary study are to better understand (1) earthquake performance of wood-frame shear walls carrying gravity loads, compared with walls without gravity load, and (2) performance of walls subjected to a sequence of earthquake motions, compared with walls subjected to a single earthquake.
Tests with simulated earthquake ground...
It is commonly accepted in the analysis of wood beams that the neutral axis coincides with the beam's centroid. However, wood is not an isotropic material, has different elastic properties in the tangential, radial and longitudinal directions, and is non-homogeneous, as it contains characteristics such as knots. Therefore, there is...
• Coniferous, diffuse‐porous and ring‐porous trees vary in their xylem anatomy, but the functional consequences of these differences are not well understood from the scale of the conduit to the individual.
• Hydraulic and anatomical measurements were made on branches and trunks from 16 species from temperate and tropical areas,...
We present an inverse modeling framework designed to constrain CO2 budgets at regional scales. The approach captures atmospheric transport processes in high spatiotemporal resolution by coupling a mesoscale model with Lagrangian Stochastic backward trajectories. Terrestrial biosphere CO₂ emissions are generated through a simple diagnostic flux model that splits the net...
The effects of surface wind speed and direction gradients on midlatitude surface vorticity and divergence fields associated with mesoscale sea surface temperature (SST) variability having spatial scales of 100–1000 km are investigated using vector wind observations from the SeaWinds scatterometer on the Quick Scatterometer (QuikSCAT) satellite and SST from the...
The relative importance of density, acoustic velocity, and microfibril angle (MFA) for the prediction of the stiffness (MOE) and strength (MOR) has not been well established for Douglas-fir (Pseudotsuga menziesii). MOE and MOR of small clear specimens of mature wood were better predicted by density and velocity than by either...
This article presents the results of an exploratory study asking faculty in the first-year writing
program and instruction librarians about their research process focusing on results specifically

incorporating serendipity into a first-year writing course.
Throughout the western United States, the invasive annual grass, medusahead (Taeniatherum caput-medusae L. Nevski), is rapidly invading grasslands once dominated by native perennial grasses, such as bluebunch wheatgrass (Pseudoroegneria spicata (Pursh) A). It is also invading grasslands dominated by less undesirable invasive annual grasses, especially cheatgrass (Bromus tectorum L.). Understanding...
The immune toxicity of the ubiquitous environmental contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), commonly referred to as dioxin, has been studied for over 35 years but only recently has the profound immune suppression induced by TCDD exposure been linked to induction of regulatory T cells (Tregs). The effects of TCDD are mediated through...
Advective skew dispersion is a natural Markov process defined ned
by a di ffusion with drift across an interface of jump discontinuity in
a piecewise constant diff usion coeffcient. In the absence of drift this
process may be represented as a function of -skew Brownian motion
for a uniquely determined...
Of 14 transgenic poplar genotypes (Populus tremula × Populus alba) with antisense 4-coumarate:coenzyme A ligase that were grown in the field for 2 years, five that had substantial lignin reductions also had greatly reduced xylem-specific conductivity compared with that of control trees and those transgenic events with small reductions in...

As part of...
Sixteen sampling alternatives were examined for their performance to quantify selected attributes of overstory conifers in riparian areas of western Oregon. Each alternative was examined at eight headwater forest locations based on a 0.52 ha square stem maps. The alternatives were evaluated for selected stand attributes (trees per hectare, basal...
Changes in ownership of limited entry permits by “local” residents of the region where a fishery occurs
may have significant economic and social implications for fishery-dependent regions. This paper
examines changes in local permit ownership in Alaska salmon fisheries, for which a long-term decline in
rural local permit ownership is...
One component of the Bering Sea Integrated Ecosystem Research Project
(BSIERP) is a spatial economic model that predicts changes in fishing
