Effects of Silviculture and Genetics on Branch/Knot Attributes of Coastal Pacific Northwest Douglas-Fir and Implications for Wood Quality—A Synthesis

Creator:: Lowell, Eini C., Maguire, Douglas A., Briggs, David G., Turnblom, Eric C., Jayawickrama, Keith J. S., and Bryce, Jed
Abstract:: Douglas-fir is the most commercially important timber species in the US Pacific Northwest due to its ecological prevalence and its superior wood attributes, especially strength and stiffness properties that make it highly prized for structural applications. Its economic significance has led to extensive establishment and management of plantations over the...

Assessment of the Biological Control Potential of Common Carabid Beetle Species for Autumn- and Winter-Active Pests (Gastropoda, Lepidoptera, Diptera: Tipulidae) in Annual Ryegrass in Western Oregon

Creator:: Reich, Inga, Jessie, Casi, Ahn, Seung-Joon, Choi, Man-Yeon, Williams, Christopher, Gormally, Mike, and Mc Donnell, Rory
Abstract:: Many studies have shown that ground beetles feed on different agricultural pests, but little is known about their species communities from US cropping systems. We assessed the biological control potential of the most common carabid beetle species in Oregon annual ryegrass grown for seed by investigating spatial and temporal overlap...

Salinity adaptation of the invasive New Zealand mud snail (Potamopyrgus antipodarum) in the Columbia River estuary (Pacific Northwest, USA): physiological and molecular studies

Creator:: Hoy, Marshal, Boese, Bruce L., Taylor, Louise, Reusser, Deborah, and Rodriguez, Rusty
Abstract:: In this study, we examine salinity stress tolerances of two populations of the invasive species New Zealand mud snail Potamopyrgus antipodarum, one population from a high salinity environment in the Columbia River estuary and the other from a fresh water lake. In 1996, New Zealand mud snails were discovered in...

Short and long-term effects of prescribed underburning on nitrogen availability in ponderosa pine stands in central Oregon

Creator:: Monleon, Vicente J., Cromack, Kermit, and Landsberg, Johanna D.
Abstract:: The effects of prescribed underburning on soil total C pools, total and inorganic N pools, and in situ net N mineralization were examined during a 1-year study in ponderosa pine (Pinus ponderosa Dougl. ex P. & C. Laws.) sites that had been experimentally burned 4 months, 5 years, or 12...

Home Range and Habitat Selection by Northern Spotted Owls on the Eastern Slope of the Cascade Mountains, Washington

Creator:: Forsman, Eric D., Sovern, Stan G., Taylor, Margaret, and Biswell, Brian L.
Abstract:: We used radiotelemetry to study space use and habitat selection of 16 Northern Spotted Owls (Strix occidentalis caurina) on the eastern slope of the Cascade Mountains, Washington, U.S.A., in 1989–1990. We used a geographical information system (GIS) and aerial photo interpretation of digital orthophotos to assign owl locations a value...

Nutrient stores and dynamics of woody detritus in a boreal forest: modeling potential implications at the stand level

Creator:: Krankina, Olga N., Harmon, Mark E., and Griazkin, Anatolii V.
Abstract:: Concentrations of 14 chemical elements (Al, B, C, Ca, Cu, Fe, K, N, Mg, Mn, Na, P, S, Zn) were measured in wood and bark of 126 sample trees representing different stages of decomposition in three major tree species of northwestern Russia: Scots pine (Pinus sylvestris L.), Norway spruce (Picea...

Spatial patterns and trends of summertime low cloudiness for the Pacific Northwest, 1996-2017

Creator:: Dye, Alex W., Rastogi, Bharat, Clemesha, Rachel E. S., Kim, John B., Samelson, Roger M., Still, Christopher J., and Williams, A. Park
Abstract:: Summertime low clouds are common in the Pacific Northwest (PNW), but spatiotemporal patterns have not been characterized. We show the first maps of low cloudiness for the western PNW and North Pacific Ocean using a 22‐year satellite‐derived record of monthly mean low cloudiness frequency for May through September and supplemented...

Identification of quantitative trait loci (QTL) for resistance to Fusarium crown rot (Fusarium pseudograminearum) in multiple assay environments in the Pacific Northwestern US

Creator:: Poole, G. J., Smiley, R. W., Paulitz, T. C., Walker, C. A., Carter, A. H., and See, D. R.
Abstract:: Fusarium crown rot (FCR), caused by and , reduces wheat ( L.) yields in the Pacific Northwest (PNW) of the US by as much as 35%. Resistance to FCR has not yet been discovered in currently grown PNW wheat cultivars. Several significant quantitative trait loci (QTL) for FCR resistance have...

Three Recent Flavors of Drought in the Pacific Northwest

Creator:: Bumbaco, Karin A. and Mote, Philip W.
Abstract:: In common with much of the western United States, the Pacific Northwest (defined in this paper as Washington and Oregon) has experienced an unusual number of droughts in the past decade. This paper describes three of these droughts in terms of the precipitation, temperature, and soil moisture anomalies, and discusses...
