Abundance, distribution, and feeding ecology of Pyrosoma atlanticum in the Northern California Current

Creator:: Schram, Julie B., Sorensen, Hilarie L., Brodeur, Richard D., Galloway, Aaron W. E., and Sutherland, Kelly R.
Abstract:: During 2016-2018, unprecedented aggregations of the colonial pelagic tunicate Pyrosoma atlanticum were observed in the Northern California Current (NCC). Pyrosomes are common in tropical and sub-tropical ocean waters, but little is known about their abundance, distribution, and trophic ecology in mid-latitude systems. To assess these factors, pyrosomes were collected during...

Trophic ecology of the neustonic cnidarian Velella velella in the northern California Current during an extensive bloom year: insights from gut contents and stable isotope analysis

Creator:: Zeman, Samantha M., Corrales‑Ugalde, Marco, Brodeur, Richard D., and Sutherland, Kelly R.
Abstract:: Aggregations of the neustonic hydrozoan Velella velella occur periodically in the northern California Current. Despite the regular occurrence of notable bloom events in this productive upwelling zone, little is known about their trophic ecology. We used gut content and stable isotope analyses (SIA) to elucidate V. velella prey selectivity and...

Range expansion of tropical pyrosomes in the northeast Pacific Ocean

Creator:: Sutherland, Kelly R., Sorenson, Hilarie L., Blondheim, Olivia N., Brodeur, Richard D., and Galloway, Aaron W. E.
Abstract:: Pyrosomes are colonial pelagic tunicates that have fascinated marine biologists for over a century. Their name comes from the “fiery” bioluminescence that luminous organs produce at night time. Blooms of pyrosomes, identified as Pyrosoma atlanticum (Peron, 1804), have recently appeared in the North Pacific Ocean, prompting questions about environmental factors...

RuzickaEvidencethatSummerJellyfishSupplementS1.zip

Creator:: Ruzicka, James J., Daly, Elizabeth A., and Brodeur, Richard D.
Abstract:: Interannual variability in salmon (Oncorhynchus spp.) production in the northeast Pacific is understood to be driven by oceanographic variability and bottom-up processes affecting prey availability to juvenile salmon. Scyphozoan jellyfish have an important role in shaping the pathways of energy flow through pelagic food webs. While jellyfish obtain high production...

Spatio-temporal associations of albacore CPUEs in the Northeastern Pacific with regional SST and climate environmental variables

Creator:: Phillips, A. Jason, Ciannelli, Lorenzo, Brodeur, Richard D., Pearcy, William G., and Childers, John
Abstract:: This study investigated the spatial distribution of juvenile North Pacific albacore (Thunnus alalunga) in relation to local environmental variability [i.e. sea surface temperature (SST)], and two large-scale indices of climate variability, [the Pacific Decadal Oscillation (PDO) and theMultivariate El Nino/Southern Oscillation Index (MEI)]. Changes in local and climate variables were...

Functional responses and scaling in predator–prey interactions of marine fishes: contemporary issues and emerging concepts

Creator:: Hunsicker, Mary E., Ciannelli, Lorenzo, Bailey, Kevin Mclean, Buckel, Jeffrey A., White, J. Wilson, Link, Jason S., Essington, Timothy E., Gaichas, Sarah, Anderson, Todd W., Brodeur, Richard D., Chan, Kung-Sik, Chen, Kun, Englund, Goran, Frank, Kenneth T., Freitas, Vania, Hixon, Mark A., Hurst, Thomas, Johnson, Darren W., Kitchell, James F., Reese, Doug, Rose, George A., Sjodin, Henrik, Sydeman, William J., van der Veer, Henk W., Vollset, Knut, and Zador, Stephani
Abstract:: Predatorprey interactions are a primary structuring force vital to the resilience of marine communities and sustainability of the worlds oceans. Human influences on marine ecosystems mediate changes in species interactions. This generality is evinced by the cascading effects of overharvesting top predators on the structure and function of marine ecosystems....

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

Creator:: Bjorkstedt, Eric P., Goericke, Ralf, McClatchie, Sam, Weber, Ed, Watson, William, Lo, Nancy, Peterson, William T., Brodeur, Richard D., Auth, Toby, Fisher, Jennifer, Morgan, Cheryl, Peterson, Jay, Largier, John, Bograd, Steven J., Durazo, Reginaldo, Gaxiola-Castro, Gilberto, Lavaniegos, Bertha, Chavez, Francisco P., Collins, Curtis A., Hannah, Bob, Field, John, Sakuma, Keith, Satterthwaite, Will, O'Farrell, Michael, Hayes, Sean, Harding, Jeff, Sydeman, William J., Thompson, Sarah Ann, Warzybok, Pete, Bradley, Russell, Jahncke, Jaime, Golightly, Richard T., Schneider, Stephanie R., Suryan, Robert M., Gladics, Amanda J., Horton, Cheryl A., Kim, Sung Yong, Melin, Sharon R., DeLong, Robert L., and Abell, Jeffrey
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...
