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...

Sydeman, William J., Thompson, Sarah Ann, Anker-Nilssen, Tycho, Arimitsu, Mayumi, Bennison, Ashley, Bertrand, Sophie, Boersch-Supan, Philipp, Boyd, Charlotte, Bransome, Nicole C., Crawford, Robert J. M., Daunt, Francis, Furness, Robert W., Gianuca, Dimas, Gladics, Amanda J., Koehn, Laura, Lang, Jennifer W., Logerwell, Elizabeth, Morris, Taryn L., Phillips, Elizabeth M., Provencher, Jennifer, Punt, André E., Saraux, Claire, Shannon, Lynne, Sherley, Richard B., Simeone, Alejandro, Wanless, Ross M., Wanless, Sarah, and Zador, Stephani

Abstract:

Worldwide, in recent years capture fisheries targeting lower-trophic level forage fish and euphausiid crustaceans have been substantial (∼20 million metric tons [MT] annually). Landings of forage species are projected to increase in the future, and this harvest may affect marine ecosystems and predator-prey interactions by removal or redistribution of biomass...

State of the California Current 2012–13: No Such Thing as an "Average" Year

Creator:

Wells, Brian K., Schroeder, Isaac D., Santora, Jarrod A., Hazen, Elliott L., Bograd, Steven J., Bjorkstedt, Eric P., Loeb, Valerie J., Mcclatchie, Sam, Weber, Edward D., Watson, William, Thompson, Andrew R., Peterson, William T., Brodeur, Richard D., Harding, Jeff, Field, John, Sakuma, Keith, Hayes, Sean, Mantua, Nathan, Sydeman, William J., Losekoot, Marcel, Thompson, Sarah Ann, Largier, John, Kim, Sung Yong, Chavez, Francisco P., Barceló, Caren, Warzybok, Pete, Bradley, Russel, Jahncke, Jaime, Goericke, Ralf, Campbell, Gregory S., Hildebrand, John A., Melin, Sharon R., Delong, Robert L., Gomez-Valdes, Jose, Lavaniegos, Bertha, Gaxiola-Castro, Gilberto, Golightly, Richard T., Schneider, Stephanie R., Lo, Nancy, Suryan, Robert M., Gladics, Amanda J., Horton, Cheryl A., Fisher, Jennifer, Morgan, Cheryl, Peterson, Jay, Daly, Elizabeth A., Auth, Toby D., and Abell, Jeffrey

Abstract:

This report reviews the state of the California Current System (CCS) between winter 2012 and spring 2013, and includes observations from Washington State to Baja California. During 2012, large-scale climate modes indicated the CCS remained in a cool, productive phase present since 2007. The upwelling season was delayed north of...

State of the California Current 2011–2012: Ecosystems Respond To Local Forcing as La Nina Wavers and Wanes

Abstract:

The state of the California Current System (CCS) since spring 2011 has evolved in response to dissipation of La Niña through spring and summer, resurgence of cooler La Niña conditions in fall and winter, and finally a transition towards ENSO-neutral conditions in spring 2012. The resurgence of La Niña was...
