Species associations and redundancy in relation to biological hotspots within the northern California Current ecosystem

Creator:: Reese, Douglas C. and Brodeur, Richard D.
Abstract:: The dynamic nature of biological hotspots, while well recognized, is not well understood. We hypothesize that the persistence of hotspots in the northern California Current System (CCS), despite seasonal and annual changes in the nekton community species composition, is related to associations among species and their functional redundancy. To address...

Efficacy and host specificity compared between two populations of the psyllid Aphalara itadori, candidates for biological control of invasive knotweeds in North America

Creator:: Grevstad, Fritzi, Shaw, Richard, Bourchier, Robert, Sanguankeo, Paolo, Cortat, Ghislaine, and Reardon, Richard C.
Abstract:: Invasive knotweeds are large perennial herbs in the Polygonaceae in the genus Fallopia that are native to Asia and invasive in North America. They include Fallopia japonica (Japanese knotweed), F. sachalinensis (giant knotweed), and a hybrid species F. x bohemica (Bohemian knotweed). Widespread throughout the continent and difficult to control...

Defining marine habitat of juvenile Chinook salmon, Oncorhynchus tshawytscha, and coho salmon, O. kisutch, in the northern California Current System

Creator:: Pool, Suzan S., Reese, Douglas C., and Brodeur, Richard D.
Abstract:: We investigated habitat use by juvenile Chinook salmon (Oncorhynchus tshawytscha) and coho salmon (O. kisutch) to identify environmental characteristics that may define their optimal marine habitat. We utilized physical and biological data from four cruises in the northern California Current system from Newport, Oregon, to Crescent City, California, in June...

Subducted seamounts and recent earthquakes beneath the central Cascadia forearc

Creator:: Tréhu, Anne M., Blakely, Richard J., and Williams, Mark C.
Abstract:: Bathymetry and magnetic anomalies indicate that a seamount on the Juan de Fuca plate has been subducted beneath the central Cascadia accretionary complex and is now located similar to 45 km landward of the deformation front. Passage of this seamount through the accretionary complex has resulted in a pattern of...

Horizontal Transfer of DNA from the Mitochondrial to the Plastid Genome and Its Subsequent Evolution in Milkweeds (Apocynaceae)

Creator:: Straub, Shannon C. K., Cronn, Richard C., Edwards, Christopher, Fishbein, Mark, and Liston, Aaron
Abstract:: Horizontal gene transfer (HGT) of DNA from the plastid to the nuclear and mitochondrial genomes of higher plants is a common phenomenon; however, plastid genomes (plastomes) are highly conserved and have generally been regarded as impervious to HGT. We sequenced the 158 kb plastome and the 690 kb mitochondrial genome...

Differential decay of human faecal Bacteroides in marine and freshwater

Creator:: Green, Hyatt C., Shanks, Orin C., Sivaganesan, Mano, Haugland, Richard A., and Field, Katharine G.
Abstract:: Genetic markers from Bacteroides and other faecal bacteria are being tested for inclusion in regulations to quantify aquatic faecal contamination and estimate public health risk. For the method to be used quantitatively across environments, persistence and decay of markers must be understood. We measured concentrations of contaminant molecular markers targeting...

Hyb-Seq: Combining target enrichment and genome skimming for plant phylogenomics

Creator:: Weitemier, Kevin, Straub, Shannon C. K., Cronn, Richard C., Fishbein, Mark, Schmickl, Roswitha, McDonnell, Angela, and Liston, Aaron
Abstract:: PREMISE OF THE STUDY: Hyb-Seq, the combination of target enrichment and genome skimming allows simultaneous data collection for low-copy nuclear genes and high-copy genomic targets for plant systematics and evolution studies. METHODS AND RESULTS: Genome and transcriptome assemblies for milkweed (Asclepias syriaca) were utilized to design enrichment probes for 3385...

Identification of Resistance to Pratylenchus neglectus and Pratylenchus thornei in Iranian Landrace Accessions of Wheat

Creator:: Thompson, Alison L., Smiley, Richard W., Paulitz, Timothy C., and Garland-Campbell, Kim
Abstract:: The pathogenic nematodes Pratylenchus neglectus (Rensch, 1924) Filipjev and Schuurmans Stekhoven, 1941 and Pratylenchus thornei Sher and Allen, 1953 cause severe yield losses in wheat (Triticum aestivum L.). The objectives in this study were to assay a collection of Iranian landrace accessions collected from 12 provinces in Iran to identify...

Mortalities of Eastern and Pacific Oyster Larvae Caused by the Pathogens Vibrio coralliilyticus and Vibrio tubiashii

Creator:: Richards, Gary P., Watson, Michael A., Needleman, David S., Church, Karlee M., and Häse, Claudia C.
Abstract:: Vibrio tubiashii is reported to be a bacterial pathogen of larval Eastern oysters (Crassostrea virginica) and Pacific oysters (Crassostrea gigas) and has been associated with major hatchery crashes, causing shortages in seed oysters for commercial shellfish producers. Another bacterium, Vibrio coralliilyticus, a well-known coral pathogen, has recently been shown to...

Process-Based Modeling to Assess the Effects of Recent Climatic Variation on Site Productivity and Forest Function across Western North America

Creator:: Waring, Richard H., Coops, Nicholas C., Mathys, Amanda, Hilker, Thomas, and Latta, Greg
Abstract:: A process-based forest growth model, 3-PG (Physiological Principles Predicting Growth), parameterized with values of soil properties constrained by satellite-derived estimates of maximum leaf area index (LAI[subscript max]), was run for Douglas-fir (Pseudotsuga menziesii) to contrast the extent to which site growth potential might vary across western North America between a...
