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...

Climate effects on red alder growth in the Pacific Northwest of North America

Creator:: Cortini, F., Comeau, P. G., Wang, T., Hibbs, D. E., and Bluhm, A.
Abstract:: We investigated the effects of climate on the growth of red alder across a broad latitudinal gradient and over a wide range of growing conditions in the Pacific Northwest of North America (PNW). Data for this study came from a study established in 1988 that includes 31 research installations located...

Trait-based approaches to linking vegetation and food webs in early-seral forests of the Pacific Northwest

Creator:: Campbell, John L. and Donato, Daniel C.
Abstract:: Both the structure and composition of naturally generated early-seral forests in the Pacific Northwest (PNW) can be profoundly different than that of more developed forest seres, especially in the period after a major disturbance but before conifers re-develop a closed canopy. While it is reasonable to suggest that the unique...

Detection and Quantification of Pratylenchus thornei in DNA Extracted from Soil Using Real-Time PCR

Creator:: Yan, Guiping, Smiley, Richard W., and Okubara, Patricia A.
Abstract:: 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...

Effect of Climate on the Distribution of Fusarium spp. Causing Crown Rot of Wheat in the Pacific Northwest of the United States

Creator:: Poole, Grant J., Smiley, Richard W., Walker, Carl, Huggins, David, Rupp, Richard, Abatzoglou, John T., Garland-Campbell, Kimberly, and Paulitz, Timothy C.
Abstract:: Fusarium crown rot (FCR) is one of the most widespread root and crown diseases of wheat in the Pacific Northwest (PNW) of the United States. Our objectives were to characterize crown rot severity and distribution throughout the PNW by conducting a survey of 210 fields covering the diverse dryland wheat-producing...

Spatiotemporal dynamics of recent mountain pine beetle and western spruce budworm outbreaks across the Pacific Northwest Region, USA

Creator:: Meigs, Garrett W., Kennedy, Robert E., Gray, Andrew N., and Gregory, Matthew J.
Abstract:: Across the western US, the two most prevalent native forest insect pests are mountain pine beetle (MPB; Dendroctonus ponderosae; a bark beetle) and western spruce budworm (WSB; Choristoneura freemani; a defoliator). MPB outbreaks have received more forest management attention than WSB outbreaks, but studies to date have not compared their...

Is the intensifying wave climate of the U.S. Pacific Northwest increasing flooding and erosion risk faster than sea level rise?

Creator:: Ruggiero, Peter
Abstract:: The relative contributions of sea level rise (SLR) and increasing extra-tropical storminess to the frequency with which waves attack coastal features is assessed with a simple total water level (TWL) model. For the coast of the U.S. Pacific Northwest (PNW) over the period of wave-buoy observations (~30 years) wave height...

Camelina: Seed Yield Response to Applied Nitrogen and Sulfur

Creator:: Wysocki, Donald J., Chastain, Thomas G., Schillinger, William F., Guy, Stephen O., and Karow, Russell S.
Abstract:: Camelina (Camelina sativa L. Crantz) has received worldwide attention in recent years as a biofuel crop and as a broadleaf option in cereal-based cropping systems. The objective of our 3-year study was to determine camelina seed yield and nitrogen use efficiency (NUE) as affected by six applied nitrogen (N) rates...

Carbon balance on federal forest lands of Western Oregon and Washington: The impact of the Northwest Forest Plan

Creator:: Krankina, Olga N., Harmon, Mark E., Schnekenburger, Frank, and Sierra, Carlos A.
Abstract:: The management of federal forest lands in the Pacific Northwest (PNW) region changed in early 1990s when the Northwest Forest Plan (NWFP) was adopted with the primary goal to protect old-growth forest and associated species. A major decline in timber harvest followed, extending an earlier downward trend. The historic and...

History of Pacific Northwest Heat Waves: Synoptic Pattern and Trends

Creator:: Bumbaco, Karin A., Dello, Kathie D., and Bond, Nicholas A.
Abstract:: A historical record of Pacific Northwest (defined here as west of the Cascade Mountains in Washington and Oregon) heat waves is identified using the U.S. Historical Climate Network, version 2, daily data (1901–2009). Both daytime and nighttime events are examined, defining a heat wave as three consecutive days above the...
