Waning magmatic activity along the Southern Explorer Ridge revealed through fault restoration of rift topography

Creator:: Deschamps, A., Tivey, M. A., Chadwick Jr., W. W., and Embley, R. W.
Abstract:: We combine high-resolution bathymetry acquired using the Autonomous Underwater Vehicle ABE with digital seafloor imagery collected using the remotely operated vehicle ROPOS across the axial valley of the Southern Explorer Ridge (SER) to infer the recent volcanic and tectonic processes. The SER is an intermediate spreading ridge located in the...

Spatial and trophic overlap of marked and unmarked Columbia River Basin spring Chinook salmon during early marine residence with implications for competition between hatchery and naturally produced fish

Creator:: Daly, Elizabeth A., Brodeur, Richard D., Fisher, Joseph P., Weitkamp, Laurie A., Teel, David J., and Beckman, Brian R.
Abstract:: Ecological interactions between natural and hatchery juvenile salmon during their early marine residence, a time of high mortality, have received little attention. These interactions may negatively influence survival and hamper the ability of natural populations to recover. We examined the spatial distributions and size differences of both marked (hatchery) and...

Identification of Burrowing Shrimp Food Sources Along an Estuarine Gradient Using Fatty Acid Analysis and Stable Isotope Ratios

Creator:: Bosley, Katelyn M., Copeman, Louise A., Dumbauld, Brett R., and Bosley, Keith L.
Abstract:: Two species of burrowing shrimp occur in high densities in US West Coast estuaries, the ghost shrimp, Neotrypaea californiensis, and the blue mud shrimp, Upogebia pugettensis. Both species of shrimp are considered ecosystem engineers as they bioturbate and irrigate extensive galleries within the sediment. While their burrows comprise a dominant...

Classification of Animal Movement Behavior through Residence in Space and Time

Creator:: Orben, Rachael A., Thompson, David R., Tolkova, Irina, and Torres, Leigh G.
Abstract:: Identification and classification of behavior states in animal movement data can be complex, temporally biased, time-intensive, scale-dependent, and unstandardized across studies and taxa. Large movement datasets are increasingly common and there is a need for efficient methods of data exploration that adjust to the individual variability of each track. We...

Multivariate Models of Adult Pacific Salmon Returns

Creator:: Burke, Brian J., Peterson, William T., Beckman, Brian R., Morgan, Cheryl, Daly, Elizabeth A., and Litz, Marisa
Abstract:: Most modeling and statistical approaches encourage simplicity, yet ecological processes are often complex, as they are influenced by numerous dynamic environmental and biological factors. Pacific salmon abundance has been highly variable over the last few decades and most forecasting models have proven inadequate, primarily because of a lack of understanding...

The mitochondrial genomes of Euphausia pacifica and Thysanoessa raschii sequenced using 454 next-generation sequencing, with a phylogenetic analysis of their position in the Malacostracan family tree

Creator:: Johansson, Mattias L., Sremba, Angela L., Feinberg, Leah R., Banks, Michael A., and Peterson, William T.
Abstract:: Euphausiid krill play a critical role in coastal and oceanic food webs, linking primary producers to upper trophic levels. In addition, some species support commercial fisheries worldwide. Despite their ecological importance, the genetics of these important species remain poorly described. To improve our understanding of the genetics of these ecological...

Relationship between oceanic mesozooplankton and energy of eddy fields

Creator:: Piontkovski, S. A., Williams, R., Peterson, William T., and Kosnirev, V. K.
Abstract:: The impact of mesoscale eddies on the spatial distribution of zooplankton biomass was analysed using data from the Arabian Sea and the Black Sea. The highest values of spatial variance of zooplankton biomass in the upper 100 to 150 m were found in regions with maximum available potential energy of...

Genetic Analyses Provide Insight into the Early Ocean Stock Distribution and Survival of Juvenile Coho Salmon off the Coasts of Washington and Oregon

Creator:: Van Doornik, Donald M., Teel, David J., Kuligowski, David R., Morgan, Cheryl A., and Casillas, Emundo
Abstract:: Estimating the stock proportions of mixed-stock fishery samples by means of genetic stock identification has played an important role in the management of salmon fisheries. In addition, stock identification of individual fish has applications for population studies, forensic cases, and management issues. We examined 11 microsatellite DNA loci in 84...

Differential gene expression between fall- and spring-run Chinook salmon assessed by long serial analysis of gene expression

Creator:: Bernier, Jeremiah C., Birkeland, Shanda R., Cipriano, Michael J., McArthur, Andrew G., and Banks, Michael A.
Abstract:: Of all Pacific salmonids, Chinook salmon Oncorhynchus tshawytscha display the greatest variability in return times to freshwater. The molecular mechanisms of these differential return times have not been well described. Current methods, such as long serial analysis of gene expression (LongSAGE) and microarrays, allow gene expression to be analyzed for...

Seasonal distribution and environmental associations among late larval and juvenile rockfish (Sebastes spp.) off Oregon and Washington: new insights based on genetics

Creator:: Johansson, Mattias L., Litz, Marisa N. C., Brodeur, Richard D., Britt, Tristan A., Vanegas, Camilo A., Hyde, John R., and Banks, Michael A.
Abstract:: Cytochrome B sequence data (FASTA format) from the paper “Seasonal distribution and environmental associations among late larval and juvenile rockfish (Sebastes spp.) off Oregon and Washington: new insights based on genetics”. The data was generated from a sample of 2534 unknown, field collected late-larval and juvenile rockfishes from the Pacific...
