Abstract:: Measurements on growth traits up to 41 years of age from 68 progeny sites in eight first-generation breeding zones of coastal Douglas-fir (Pseudotsuga menziesii [MIRB.] FRANCO var. menziesii) in the US Pacific Northwest were used to investigate age trends of genetic parameters and to determine optimum age of selection. Heritabilities...

Creator:: McCune, Bruce
Abstract:: Questions: Can a statistical model be designed to represent more directly the nature of organismal response to multiple interacting factors? Can multiplicative ernel smoothers be used for this purpose? What advantages does this approach have over more traditional habitat modelling methods? Methods: Non-parametric multiplicative regression (NPMR)was developed from the premises...

Creator:: Mincher, Bruce J., Precek, Martin, and Paulenova, Alena
Abstract:: The radiolytic changes in oxidation state for solutions of initially Np(V) and/or Np(VI) were investigated by gamma-irradiation in conjunction with UV/Vis spectroscopy of the aqueous phase. Samples were irradiated in varying concentrations of nitric acid, and with or without the presence of 30 % TBP in dodecane. At short irradiation...

Creator:: McGough, Bruce, Plantinga, Andrew J., and Costello, Christopher
Abstract:: Empirical evidence indicates that environmental fluctuations have important effects on fisheries production. However, existing analytical solutions of stochastic fisheries models have been produced only under highly simplified economic and biological conditions. The main contribution of this paper is to derive under general conditions a policy function for the management of...

Creator:: Twohy, Cynthia and Gandrud, Bruce W.
Abstract:: Ice crystal larger than about 5 μm diameter were separated from interstitial particles in aircraft contrails and evaporated. Residual particles larger than 0.1 μm were analyzed by electron microscopy. Soot, metals, and volatile organic substances, apparently from the aircraft exhaust, were found. However, the residual particles also contained high percentages...

Creator:: Chen, Yong and Weber, Bruce
Abstract:: "In this paper, we use community-level data from Oregon’s 234 rural communities, which we define as incorporated cities with less than 50,000 people, to analyze Federal forest policy. We hypothesize that positive policy impacts due to amenity-related migration were confined to nearby communities, while the negative impacts due to mill...

Creator:: Risien, Julie and Goldstein, Bruce Evan
Abstract:: We present an in-depth case study of a learning network that aims to transform infrastructure and practice across the research enterprise to advance societal impacts. The theory of social morphogenesis guides our processual qualitative analysis of the network. We describe how different types of boundary work, both building and navigating...

Abstract:: We describe Umbilicaria nodulospora, a distinctive new species occurring on steep rock faces on old lava flows in California and Oregon. The species is unusual among lichenized ascomycetes in consistently having one or two shallowly bulging knobs at one end of each ascospore, suggesting a T, Y, or L shape;...

Creator:: Eerkes-Medrano, Dafne, Menge, Bruce A., Sislak, Christine, and Langdon, Christopher J.
Abstract:: Hypoxia is increasing in coastal zones worldwide, with acute effects on demersal fish and benthic invertebrate communities in shallow coastal and estuarine habitats. Less studied are the effects of hypoxia on planktonic larvae of open coastal habitats. Climate change projections suggest intensified hypoxia in open coast upwelling systems, such as...

Abstract:: Spatial variation of available food resources can be difficult to accurately quantify for wide ranging organisms at landscape scales. Lichens with usnic acid, a yellowish pigment, constitute a large portion of caribou winter diet across much of their range. We take a new approach of modeling lichen abundances by capitalizing...
