Marine Heatwaves Influence Depth Preferences of Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Teahan, Andrew
Abstract:: Marine heatwaves have become more common over the past several years. The 2014-2015 ‘warm blob’ had profound effects on marine ecosystems in the Northeast Pacific. Given the particular habitat needs of Chinook Salmon (Oncorhynchus tshawytscha) we wanted to examine the impacts of the heatwave on Chinook depth distribution. We examined...

Distributions of Dungeness crab (Cancer magister) zoea in the California Current: Closing a life history gap

Creator:: Chin, Andrew
Abstract:: Dungeness crab (Cancer magister) is an important commercial species along the west coast of North America, and its population dynamics are highly influenced by interactions between environmental variability and early life history distribution. However, the distribution of the early larvae stages of Dungeness crab offshore is poorly known. To fill...

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...

Environmental and Ecological Effects of Ocean Renewable Energy Development: A Current Synthesis

Creator:: Boehlert, George W. and Gill, Andrew B.
Abstract:: Marine renewable energy promises to assist in the effort to reduce carbon emissions worldwide. As with any large-scale development in the marine environment, however, it comes with uncertainty about potential environmental impacts, most of which have not been adequately evaluated—in part because many of the devices have yet to be...

Interannual variability in the Northern California Current food web structure: Changes in energy flow pathways and the role of forage fish, euphausiids, and jellyfish

Creator:: Ruzicka, James J., Brodeur, Richard D., Emmett, Robert L., Steele, John H., Zamon, Jeannette E., Morgan, Cheryl A., Thomas, Andrew C., and Wainwright, Thomas C.
Abstract:: The Northern California Current (NCC) is a seasonally productive and open ecosystem. It is home to both a diverse endemic community and to seasonally transient species. Productivity and food web structure vary seasonally, interannually, and decadally due to variability in coastal upwelling, climate-scale physical processes, and the migratory species entering...

Characterizing neutral and adaptive genomic differentiation in a changing climate: The most northerly freshwater fish as a model

Creator:: O'Malley, Kathleen G., Vaux, Felix, and Black, Andrew N.
Abstract:: Arctic freshwater ecosystems have been profoundly affected by climate change. Given that the Arctic charr (Salvelinus alpinus) is often the only fish species inhabiting these ecosystems, it represents a valuable model for studying the impacts of climate change on species life‐history diversity and adaptability. Using a genotyping‐by‐se‐ quencing approach, we...

Winter dispersal and activity patterns of post-breeding black-legged kittiwakes Rissa tridactyla from Prince William Sound, Alaska

Creator:: McKnight, Aly, Irons, David B., Allyn, Andrew J., Sullivan, Kelsey M., and Suryan, Robert M.
Abstract:: As colony-specific wintering ecology of small and medium-sized seabirds is poorly understood, it has been generally assumed that winter conditions have the same effect on all individuals from any given colony. However, advances in global positioning technology now allow researchers to investigate movements of smaller seabirds. We tracked black-legged kittiwakes...

Recruitment, Growth and Mortality of an Antarctic Hexactinellid Sponge, Anoxycalyx joubini

Creator:: Dayton, Paul K., Kim, Stacy, Jarrell, Shannon C., Oliver, John S., Hammerstrom, Kamille, Fisher, Jennifer L., O'Connor, Kevin, Barber, Julie S., Robilliard, Gordon, Barry, James, Thurber, Andrew R., and Conlan, Kathy
Abstract:: Polar ecosystems are sensitive to climate forcing, and we often lack baselines to evaluate changes. Here we report a nearly 50-year study in which a sudden shift in the population dynamics of an ecologically important, structure-forming hexactinellid sponge, Anoxycalyx joubini was observed. This is the largest Antarctic sponge, with individuals...
