A new species of Sebastes (Scorpaeniformes: Sebastidae) from the northeastern Pacific, with a redescription of the blue rockfish, S. mystinus (Jordan and Gilbert, 1881)

Creator:: Frable, Benjamin W., Wagman, D. Wolfe, Frierson, Taylor N., Aguilar, Andres, and Sidlauskas, Brian L.
Abstract:: The diverse predatory rockfishes (Sebastes spp.) support extensive commercial fisheries in the northeastern Pacific. Although 106 species of Sebastes are considered valid, many of the ecological, geographical, and morphological boundaries separating them lack clarity. We clarify one such boundary by separating the blue rockfish Sebastes mystinus (Jordan and Gilbert, 1881)...

Fish-habitat associations on a deep reef at the edge of the Oregon continental shelf

Creator:: Tissot, Brian N., Hixon, Mark Anthony, Barss, William, and Stein, David L.
Abstract:: Heceta Bank is a large reef on the edge of the central Oregon continental shelf that supports a wide variety of commercial fisheries. Using the research submersible Delta, we studied fish abundances on Heceta Bank and the relationship between species composition of fish assemblages and bottom types. Cluster analysis indicated...

Pre- and Postinfection Activity of Fungicides in Control of Hop Downy Mildew

Creator:: Gent, David H., Twomey, Megan C., Wolfenbarger, Sierra N., and Woods, Joanna L.
Abstract:: Optimum timing and use of fungicides for disease control are improved by an understanding of the characteristics of fungicide physical mode of action. Greenhouse and field experiments were conducted to quantify and model the duration of pre- and postinfection activity of fungicides most commonly used for control of hop downy...

Development of Molecular Markers for Determining Continental Origin of Wood from White Oaks (Quercus L. sect. Quercus)

Creator:: Schroeder, Hilke, Cronn, Richard, Yanbaev, Yulai, Jennings, Tara, Mader, Malte, Degen, Bernd, and Kersten, Birgit
Abstract:: To detect and avoid illegal logging of valuable tree species, identification methods for the origin of timber are necessary. We used next-generation sequencing to identify chloroplast genome regions that differentiate the origin of white oaks from the three continents; Asia, Europe, and North America. By using the chloroplast genome of...

Crop damage caused by powdery mildew on hop and its relationship to late season management

Creator:: Gent, D. H., Grove, G. G., Nelson, M. E., Wolfenbarger, S. N., and Woods, J. L.
Abstract:: Powdery mildew of hop (Podosphaera macularis) may cause economic loss due to reductions in cone yield and quality. Quantitative estimates of crop damage from powdery mildew remain poorly characterized, especially the effect of late season disease management on crop yield and quality. Field studies in Washington State evaluated cone yield,...

Relationship Between Specific Gravity and Percentage of Summerwood in Wide-Ringed, Second-Growth Douglas-Fir

Creator:: Smith, Diana M.
Abstract:: For the sample of wide-ringed Douglas-fir discussed in this report, the relationship between specific gravity and percentage of summerwood is linear over a range of 16 to 60 percent summerwood content of the annual ring. The specific gravity of the summerwood and springwood portions of 96 dissected annual rings is...

Seasonal and interannual variation in juvenile salmonids and associated fish assemblage in open waters of the lower Columbia River estuary

Creator:: Weitkamp, Laurie A., Bentley, Paul J., and Litz, Marisa N. C.
Abstract:: The transition between freshwater and marine environments is associated with high mortality for juvenile anadromous salmonids, yet little is known about this critical period in many large rivers. To address this deficiency, we investigated the estuarine ecology of juvenile salmonids and their associated fish assemblage in open-water habitats of the...

From fossils to phylogenies

Creator:: Goodwin, Baylee N., Besser, August D., and Ramsey, Stephen A.
Abstract:: The research question address in this study is, “To what extent will the use of hands-on activities for introducing concepts in bioinformatics promote student engagement in after-school STEM club settings?” It is hypothesized that high school students' engagement in hands-on bioinformatics activities promotes their awareness of, and interest in, STEM...

Flow Management for Hydropower Extirpates Aquatic Insects, Undermining River Food Webs

Creator:: Kennedy, Theodore A., Muehlbauer, Jeffrey D., Yackulic, Charles B., Lytle, David A., Miller, Scott W., Dibble, Kimberly L., Kortenhoeven, Eric W., Metcalfe, Anya N., and Baxter, Colden V.
Abstract:: Dams impound the majority of rivers and provide important societal benefits, especially daily water releases that enable on-peak hydroelectricity generation. Such “hydropeaking” is common worldwide, but its downstream impacts remain unclear. We evaluated the response of aquatic insects, a cornerstone of river food webs, to hydropeaking using a life history–hydrodynamic...
