Evidence for mate selection in captive-breeding rockfishes (genus Sebastes): inference from parentage analysis and the major histocompatibility complex (MHC)

Creator:: Johansson, M. L., Clifford, K., Fodness, B., Vazquez, N. A., and Banks, M. A.
Abstract:: Rockfish species of the genus Sebastes are notable for being numerous and diverse. Rockfishes are unusual among fish because they fertilize their eggs internally and release live, swimming larvae. They undergo complex courting behaviors, which may allow females to be selective about their mates. The major histocompatibility complex (MHC) has...

Management of Pacific Rockfish

Creator:: Parker, S. J., Berkeley, S. A., Golden, J. T., Gunderson, D. R., Heifetz, J., Hixon, M. A., Larson, R., Leaman, B. M., Love, M. S., Musick, J. A., O'Connell, V. M., Ralston, S., Weeks, H. J., and Yoklavich, M. M.
Abstract:: The American Fisheries Society (AFS) recognizes the need for conservative and robust management of Pacific rockfishes because of naturally low population growth, the overfished state of many of the stocks, and complex nature of the mixed-stock fisheries (60-plus species). The AFS recommends that catch information be collected on a species-specific...

Cold front induced changes on the Florida panhandle shelf during October 2008

Creator:: Kamykowski, D., Morrison, J. M., McCulloch, A. A., Nyadjro, E. S., Thomas, C. A., Sinclair, G. A., and Grabowski Pridgen, K.
Abstract:: A significant step transition between seasonally stratified and destratified hydrographic conditions occurred during an October 2008 cruise to the Florida Panhandle Shelf along a cross-shelf transect that was sampled before and after a cold front passed through the area. Meteorological measurements from nearby ocean and land-based stations characterized the event....

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...

Tracking North Pacific Humpback Whales To Unravel Their Basin-Wide Movements

Creator:: Palacios, Daniel M., Mate, Bruce R., Baker, C. Scott, Hayslip, Craig E., Follett, Thomas M., Steel, Debbie, Lagerquist, Barbara A., Irvine, Ladd M., and Winsor, Martha H.
Abstract:: In 2014, Oregon State University (OSU) initiated a multi-year project to study humpback whale (Megaptera novaeangliae) migrations in the North Pacific Ocean using satellite tracking technology in combination with genetic and photo-identification (photo-ID) analyses. The study is highly relevant to management, given the need for new information arising from the...

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...

Overlap of North Pacific albatrosses with the U.S. west coastgroundfish and shrimp fisheries

Creator:: Guy, T. J., Jennings, S. L., Suryan, R. M., Melvin, E. F., Bellman, M. A., Ballance, L. T., Blackie, B. A., Croll, D. A., Deguchi, T., Geernaert, T. O., Henry, R. W., Hester, M., Hyrenbach, K. D., Jahncke, J., Kappes, M. A., Ozaki, K., Roletto, J., Sato, F., Sydeman, W. J., and Zamon, J. E.
Abstract:: We used a combination of seabird data (both fishery-dependent and fishery-independent) and fishing-effort data to evaluate the relative fisheries risk of five west coast groundfish fisheries and oneshrimp fishery to black-footed (Phoebastria nigripes), short-tailed (P. albatrus) and Laysan albatrosses(P. immutabilis). To assess risk, an overlap index was derived as the...

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...

Development of a Standardized DNA Database for Chinook Salmon

A., Moran, P., Narum, S. R., Stephenson, J. J., Supernault, K. J., Teel, D. J., Templin, W. D., Wenburg, J. K., Young, S. F., and Smith, C. T.
Abstract:: An international multi-laboratory project was conducted to develop a standardized DNA database for Chinook salmon (Oncorhynchus tshawytscha). This project was in response to the needs of the Chinook Technical Committee of the Pacific Salmon Commission to identify stock composition of Chinook salmon caught in fisheries during their oceanic migrations. Nine...

Linking predators to seasonality of upwelling: Using food web indicators and path analysis to infer trophic connections

Creator:: Thompson, Sarah Ann, Sydeman, William J., Santora, Jarrod A., Black, Bryan A., Suryan, Robert M., Calambokidis, John, Peterson, William T., and Bograd, Steven J.
Abstract:: Upwelling in eastern boundary current systems is a primary driver of ecosystem productivity. Typically, peak upwelling occurs during spring and summer, but winter upwelling may also be important to ecosystem functions. In this study, we investigated the hypothesis that winter and spring/summer upwelling, operating through indirect trophic interactions, are important...
