Evaluation of methyl salicylate lures on populations of Typhlodromus pyri (Acari: Phytoseiidae) and other natural enemies in western Oregon vineyards

Creator:: Gadino, Angela N., Walton, Vaughn M., and Lee, Jana C.
Abstract:: Methyl salicylate (MeSA), a herbivore-induced plant volatile, can elicit control of pests through attraction of beneficial arthropods. This study evaluates the effect of synthetic MeSA lures (PredaLure) on arthropod populations during the 2009 and 2010 seasons in two Oregon vineyards (Dayton and Salem). MeSA lures were deployed at a low...

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...

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...

Simulation of Water and Energy Fluxes in an Old-Growth Seasonal Temperate Rain Forest Using the Simultaneous Heat and Water (SHAW) Model

Creator:: Link, Timothy E., Flerchinger, Gerald N., Unsworth, Mike, and Marks, Danny
Abstract:: In the Pacific Northwest (PNW), concern about the impacts of climate and land cover change on water resources and flood-generating processes emphasizes the need for a mechanistic understanding of the interactions between forest canopies and hydrologic processes. Detailed measurements during the 1999 and 2000 hydrologic years were used to modify...

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...

Cesium radioisotope content of wild edible fungi, mineral soil, and surface litter in western North America after the Fukushima nuclear accident

Creator:: Trappe, Matthew J., Minc, Leah D., Kittredge, Kimberly S., and Pink, Jeremias W.
Abstract:: We measured activity levels of cesium radioisotopes ¹³⁴Cs and ¹³⁷Cs in wild edible fungi, mineral soil, and surface litter of the west coast of North America from southern California to northern Vancouver Island after the Fukushima nuclear accident. All activity measurements were below governmental limits for human health. ¹³⁷Cs activity...

The effect of local stand structure on growth and growth efficiency in heterogeneous stands of ponderosa pine and lodgepole pine in central Oregon

Creator:: Mainwaring, Douglas B. and Maguire, Douglas A. (Douglas Alan)
Abstract:: Basal area and height growth were analyzed for individual trees in uneven-aged ponderosa pine (Pinus ponderosa Dougl. ex Laws.) and lodgepole pine (Pinus contorta Dougl. ex. Loud.) stands in central Oregon. Basal area growth was modeled as a function of other stand and tree variables to address three general objectives:...

Estimating Canopy Cover from Standard Forest Inventory Measurements in Western Oregon

Creator:: McIntosh, Anne C.S., Gray, Andrew N., and Garman, Steven L.
Abstract:: Reliable measures of canopy cover are important in the management of public and private forests. However, direct sampling of canopy cover is both labor- and time-intensive. More efficient methods for estimating percent canopy cover could be empirically derived relationships between more readily measured stand attributes and canopy cover or, alternatively,...

Evaluation and improvement of the Community Land Model (CLM4) in Oregon forests

Creator:: Hudiburg, T. W., Law, B. E., and Thornton, P. E.
Abstract:: Ecosystem process models are important tools for determining the interactive effects of global change and disturbance on forest carbon dynamics. Here we evaluated and improved terrestrial carbon cycling simulated by the Community Land Model (CLM4), the land model portion of the Community Earth System Model (CESM1.0.4). Our analysis was conducted...

Potential for ethanol production from conservation reserve program lands in Oregon

Creator:: Juneja, Ankita, Kumar, Deepak, Williams, John D., Wysocki, Donald J., and Murthy, Ganti S.
Abstract:: Increase in energy demand has led towards considering lignocellulosic feedstocks as potential for ethanol production. Aim of this study was to estimate the potential of grass straws from conservation reserve program (CRP) lands as feedstocks for ethanol production. The CRP was initiated to ensure reduction in soil erosion with a...
