A bioenergetics model to evaluate demographic consequences of disturbance in marine mammals applied to gray whales

Creator:: Villegas-Amtmann, S., Schwarz, L. K., Sumich, J. L., and Costa, D. P.
Abstract:: While sophisticated tools are used to monitor behavioral changes of large marine vertebrates, determining whether these changes are meaningful for management and conservation is challenging. The Population Consequences of Disturbance model proposed a bioenergetics model to detect biologically meaningful population responses, where disturbance costs are linked to lost energy. The...

Two Cell Lines from White Sturgeon

Creator:: Hedrick, Ronald P., McDowell, Terry S., Rosemark, Renee, Aronstein, Diane, and Lannan, Catharine N.
Abstract:: Cell lines were established from spleen and heart tissues of a juvenile white sturgeon Acipenser transmontanus and designated WSS-2 and WSH-1, respectively. Isoenzyme analyses of both lines confirmed their host of origin. Both lines were hypotetraploid and possessed micro- and macrochromosomes. The modal chromosome number for the WSS-2 line was...

Infectivity of a rickettsia isolated from coho salmon Oncorhynchus kisutch

Creator:: Garces, L. H., Larenas, J. J., Smith, P. A., Sandino, S., Lannan, C. N., and Fryer, J. L.
Abstract:: Two species of salmonids were tested for their susceptibility to infection by a rickettsia isolated in cell culture from diseased coho salmon Oncorhynchus kisutch in Chile. Mortality approached 100% in coho and Atlantic salmon Salmo salar injected with 10-fold dilutions of cell culture medium containing the rickettsia. Typical disease signs...

Flux measurements of explosive degassing using a yearlong hydroacoustic record at an erupting submarine volcano

Creator:: Dziak, R. P., Baker, E. T., Shaw, A. M., Bohnenstiehl, D. R., Chadwick, W. W., Jr., Haxel, J. H., Matsumoto, H., and Walker, S. L.
Abstract:: The output of gas and tephra from volcanoes is an inherently disorganized process that makes reliable flux estimates challenging to obtain. Continuous monitoring of gas flux has been achieved in only a few instances at subaerial volcanoes, but never for submarine volcanoes. Here we use the first sustained (yearlong) hydroacoustic...

Seismic precursors and magma ascent before the April 2011 eruption at Axial Seamount

Creator:: Dziak, R. P., Haxel, J. H., Bohnenstiehl, D. R., Chadwick, W. W., Jr., Nooner, S. L., Fowler, M. J., Matsumoto, H., and Butterfield, D. A.
Abstract:: Volcanoes at spreading centres on land often exhibit seismicity and ground inflation months to years before an eruption, caused by a gradual influx of magma to the source reservoir¹⁻⁴. Deflation and seismicity can occur on time scales of hours to days, and result from the injection of magma into adjacent...

Development of a Standardized DNA Database for Chinook Salmon

Creator:: Seeb, L. W., Antonovich, A., Banks, Michael A., Beacham, T. D., Bellinger, M. R., Blankenship, S. M., Campbell, M. R., Decovich, N. A., Garza, J. C., Guthrie III, C. M., Lundrigan, T. 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...

Volcanic Eruptions in the Deep Sea

Abstract:: Volcanic eruptions are important events in Earth’s cycle of magma generation and crustal construction. Over durations of hours to years, eruptions produce new deposits of lava and/or fragmentary ejecta, transfer heat and magmatic volatiles from Earth’s interior to the overlying air or seawater, and significantly modify the landscape and perturb...

Spatiotemporal distribution of the seismicity along the Mid-Atlantic Ridge north of the Azores from hydroacoustic data: Insights into seismogenic processes in a ridge-hot spot context

Creator:: Goslin, J., Perrot, J., Royer, J. -Y., Martin, C., Lourenco, N., Luis, J., Dziak, R. P., Matsumoto, H., Haxel, J., Fowler, M. J., Fox, C. G., Lau, A. T. -K., and Bazin, S.
Abstract:: The seismicity of the North Atlantic was monitored from May 2002 to September 2003 by the ‘SIRENA array’ of autonomous hydrophones. The hydroacoustic signals provide a unique data set documenting numerous low-magnitude earthquakes along the section of the Mid-Atlantic Ridge (MAR) located in a ridge-hot spot interaction context. During the...

An Evaluation of the Influence of Stock Origin and Outmigration History on the Disease Susceptibility and Survival of Juvenile Chinook Salmon

Creator:: Dietrich, Joseph P., Boylen, Deborah A., Thompson, Donald E., Loboschefsky, Erik J., Bravo, Claudia F., Spangenberg, Dina K., Ylitalo, Gina M., Collier, Tracy K., Fryer, Derek S., Arkoosh, Mary R., and Loge, Frank J.
Abstract:: Various methods have been developed to mitigate the adverse effects of the Federal Columbia River Power System on juvenile Pacific salmon out-migrating through the Columbia River basin. In this study, we found that hatchery-reared spring Chinook salmon Oncorhynchus tshawytscha in the river are in varying degrees of health, which may...
