Cupric Oxide (CuO) Oxidation Detects Pyrogenic Carbon in Burnt Organic Matter and Soils

Creator:: Hatten, Jeff and Goñi, Miguel
Abstract:: Wildfire greatly impacts the composition and quantity of organic carbon stocks within watersheds. Most methods used to measure the contributions of fire altered organic carbon–i.e. pyrogenic organic carbon (Py-OC) in natural samples are designed to quantify specific fractions such as black carbon or polyaromatic hydrocarbons. In contrast, the CuO oxidation...

Long-Term Soil Productivity in Christmas Tree Farms of Oregon and Washington: A Comparative Analysis between First- and Multi-Rotation Plantations

Creator:: Hatten, Jeff, Landgren, Chal, and Hart, John
Abstract:: Christmas tree production removes organic matter and associated nutrients from a site and can change soil physical properties, reduce mycorrhizal populations, and result in pesticide over-use/accumulation. These impacts have been implicated in potential field productivity declines. Assessing Christmas tree productivity is complicated by genetics, management, and market forces. We approached...

Growth, survival, and habitat use of naturally reared and hatchery steelhead fry in streams: effects of an enriched hatchery rearing environment

Creator:: Tatara, Christopher P., Riley, Stephen C., and Scheurer, Julie A.
Abstract:: After hatchery-reared salmonids are released into the wild, their survival and performance are frequently lower than those of wild conspecifics. Additionally, negative effects of hatchery fish on wild fish are cited as factors affecting the recovery of salmonid populations. Alternative hatchery rearing environments and release practices have been proposed to...

Creator:: Rempel, Hannah Gascho and Bridges, Laurie
Abstract:: As mobile technologies continue to evolve, libraries seek sustainable ways to keep up with these changes and to best serve our users. Previous library mobile usability research has examined tasks users predict they might be likely to perform, but little is known about what users actually do on a mobile-optimized...

Trap Designs for Monitoring Drosophila suzukii (Diptera: Drosophilidae)

Creator:: Lee, Jana C., Shearer, Peter W., Barrantes, Luz D., Beers, Elizabeth H., Burrack, Hannah J., Dalton, Daniel T., Dreves, Amy J., Gut, Larry J., Hamby, Kelly A., Haviland, David R., Isaacs, Rufus, Nielsen, Anne L., Richardson, Tamara, Rodriguez-Saona, Cesar R., Stanley, Cory A., Walsh, Doug B., Walton, Vaughn M., Yee, Wee L., Zalom, Frank G., and Bruck, Denny J.
Abstract:: Drosophila suzukii (Matsumura), an invasive pest of small and stone fruits, has been recently detected in 39 states of the United States, Canada, Mexico, and Europe. This pest attacks ripening fruit, causing economic losses including increased management costs and crop rejection. Ongoing research aims to improve the efficacy of monitoring...

Total kinetic energy release in the fast neutron induced fission of actinide nuclei

Creator:: Loveland, Walter
Abstract:: The total kinetic energy release and fission mass distributions for the fast neutron (En = 3–100 MeV) induced fission of 232Th, 233U, 235U, 237Np, 239Pu, 240Pu, and 242Pu have been measured using the LANSCE facility. The neutron energies were deduced from time-of- flight measurements. The fission fragments were detected using...

Induced IL-10 Splice Altering Approach to Antiviral Drug Discovery

Creator:: Panchal, Rekha G., Mourich, Dan V., Bradfute, Steven, Hauck, Laura L., Warfield, Kelly L., Iversen, Patrick L., and Bavari, Sina
Abstract:: Ebola virus causes an acute hemorrhagic fever lethal in primates and rodents. The contribution of host immune factors to pathogenesis has yet to be determined and may reveal efficacious targets for potential treatment. In this study, we show that the interleukin (IL)-10 signaling pathway modulates Ebola pathogenesis. IL-10 [superscript -...

Comparison of growth, behavior and lipid concentrations of walleye pollock Theragra chalcogramma larvae fed lipid-enriched, lipid-deficient and field-collected prey

Creator:: Davis, Michael W. and Olla, Bori L.
Abstract:: While growth and survival of marine fish larvae in the sea may be dependent on prey type, size and concentration, nutritional quality of prey may also play an important role. This study investigates the relationships of lipid content of prey with growth, gas bladder size, sinking rate, behavior and survival...

An unusual ascospore shape and a new species, Umbilicaria nodulospora (Umbilicariaceae), from California and Oregon

Creator:: McCune, Bruce, Di Meglio, Joseph, and Curtis, Marc J.
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;...
