Temporal and crustal effects on differentiation of tholeiite to calcalkaline and ferro-trachytic suites, High Lava Plains, Oregon, USA

Creator:: Streck, Martin J. and Grunder, Anita L.
Abstract:: Strongly bimodal, basalt-rhyolite volcanism of the High Lava Plains Province of Oregon followed the Middle Miocene flood basalts of the Pacific Northwest and extends to recent time. During the 8 m.y. of volcanism recorded in the central High Lava Plains, in western Harney Basin, three distinct mafic magmatic trends originate...

The redox chemistry of neptunium in γ-irradiated aqueous nitric acid in the presence of an organic phase

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...

Contributions of ectomycorrhizal fungal mats to forest soil respiration

Creator:: Phillips, C. L., Kluber, L. A., Martin, J. P., Caldwell, B. A., and Bond, B. J.
Abstract:: Distinct aggregations of fungal hyphae and rhizomorphs, or "mats", formed by some genera of ectomycorrhizal (EcM) fungi are common features of soils in coniferous forests of the Pacific Northwest. We measured in situ respiration rates of Piloderma mats and neighboring non-mat soils in an old-growth Douglas-fir forest in western Oregon...

Metagenome sequence of Elaphomyces granulatus from sporocarp tissue reveals Ascomycota ectomycorrhizal fingerprints of genome expansion and a Proteobacteria-rich microbiome

Creator:: Quandt, C. Alisha, Kohler, Annegret, Hesse, Cedar N., Sharpton, Thomas J., Martin, Francis, and Spatafora, Joseph W.
Abstract:: Many obligate symbiotic fungi are difficult to maintain in culture, and there is a growing need for alternative approaches to obtaining tissue and subsequent genomic assemblies from such species. In this study, the genome of Elaphomyces granulatus was sequenced from sporocarp tissue. The genome assembly remains on many contigs, but...

Individual snag detection using neighborhood attribute filtered airborne lidar data

Creator:: Wing, Brian M., Ritchie, Martin W., Boston, Kevin, Cohen, Warren B., and Olsen, Michael J.
Abstract:: The ability to estimate and monitor standing dead trees (snags) has been difficult due to their irregular and sparse distribution, often requiring intensive sampling methods to obtain statistically significant estimates. This study presents a new method for estimating and monitoring snags using neighborhood attribute filtered airborne discrete-return lidar data. The...

Seasonal Phenology of Amphorophora agathonica (Hemiptera: Aphididae) and Spread of Viruses in Red Raspberry in Washington

Creator:: Lightle, D. M., Quito-Avila, D., Martin, R. R., and Lee, J. C.
Abstract:: Amphorophora agathonica (Hottes) is the primary vector of aphid-transmitted viruses in red raspberry in the Pacific Northwest region of the United States. To better understand the biology of the aphid, we estimated the lower developmental threshold and studied the seasonal activity of A. agathonica in commercial fields in northern Washington...

ecoOcean - games in Fisheries education, communication and science

Creator:: Schmidt, J., Voss, Rudi, Nissen, Dennis, Magens, Michel, Quaas, Martin, and Requate, Till
Abstract:: There is growing realization of the potential for games and experiments as powerful tools for education, outreach and research in many fields of science. Particularly in fisheries management we face a growing demand for stakeholder involvement, which requires new ways in reaching informed decision making. Games and experiments can be...

Modulation of the sea-surface temperature in the Southeast Pacific by the atmospheric low-level coastal jet

Creator:: Hong, Xiaodong, Wang, Shouping, Holt, Teddy R., Martin, Paul J., and O’Neill, Larry
Abstract:: The atmospheric low-level coastal jet (LLCJ) in the Southeast Pacific (SEP) region is characterized as either a strong-forcing jet (colder and drier air) or weak-forcing jet (warm and moist) based on the location of the Southeast Pacific high-pressure system (SEPH). The sea-surface temperature (SST) changes corresponding to a particularly strong-forcing...

Economic Impacts of Hypoxia on North Carolina Brown Shrimp

Creator:: Huang, Ling, Nichols, Lauren A. B., Craig, J. Kevin, and Smith, Martin D.
Abstract:: While environmental stressors such as hypoxia (low dissolved oxygen) are perceived as a threat to the productivity of coastal ecosystems, policy makers have little information about the economic consequences for fisheries. Prior studies based on data aggregated at relatively large spatial (e.g.,1000s km) and temporal (e.g., annual) scales have typically...

Prediction of understory vegetation cover with airborne lidar in an interior ponderosa pine forest

Creator:: Wing, Brian M., Ritchie, Martin W., Boston, Kevin, Cohen, Warren B., Gitelman, Alix, and Olsen, Michael J.
Abstract:: Forest understory communities are important components in forest ecosystems providing wildlife habitat and influencing nutrient cycling, fuel loadings, fire behavior and tree species composition over time. One of the most widely utilized understory component metrics is understory vegetation cover, often used as a measure of vegetation abundance. To date, understory...
