Patterns of distribution, abundance, and change over time in the marine bird community of Prince William Sound, Alaska, 1989-2012

Creator:: Cushing, Daniel A.
Abstract:: Over recent decades, the marine ecosystems of Prince William Sound (PWS), Alaska have experienced the concurrent effects of a major anthropogenic disturbance, the 1989 Exxon Valdez oil spill (EVOS), and a dynamic atmospheric-oceanic environment. Studies of top marine consumers can provide insights into processes of ecosystem change. Using data collected...

Atlantic Puffin (Fratercula arctica) Foraging Ecology During Marine Heatwave Conditions

Creator:: Kennerley, William L.
Abstract:: Marine heatwaves (“MHWs”) are discrete periods of anomalously warm ocean conditions that can lead to shifts in the distribution and abundance of marine organisms. Low-trophic level, pelagic forage species are frequently among those affected by MHWs, often resulting in considerable impacts upon their predators. In the North Atlantic Ocean, Atlantic...

Grow fast or die young: influence of ocean conditions and larval growth on patterns of selective mortality and settlement variability of rockfishes

Creator:: Fennie, Hamilton William
Abstract:: Most benthic marine fishes have a biphasic life cycle with a dispersive pelagic larval stage that spends weeks to months in the plankton before metamorphosing into juveniles and settling to benthic habitats. The magnitude of mortality during the early life stages of marine fishes typically drives variability in year-class strength....

Trophic dynamics of marine nekton and zooplankton in the Northern California Current ecosystem

Creator:: Miller, Todd William
Abstract:: The Northern California Current (NCC) ecosystem exhibits extreme seasonal, interannual and interdecadal shifts in the abiotic environment and shifts in primary and higher production. This variability is also apparent in the spatial structure of the ecosystem with nearshore-shelf waters (<150 m isobath) being highly productive and having a different community...

Influence of wetland landscape structure of shorebirds wintering in an agricultural valley

Creator:: Taft, Oriane Williams
Abstract:: Understanding how wetland birds use habitat is pivotal to developing successful and beneficial conservation strategies. Although it has been an ardent topic in forest research for some time, how species interact with the spatial patterning of habitat across a landscape (i.e., landscape structure) has been more or less neglected in...

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....

Best practices for assessing forage fish fisheries-seabird resource competition

Creator:: 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...

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...

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...

Variability in mesoscale circulation and its effects on zooplankton distribution in the Northern California Current

Creator:: Keister, Julie Eileen
Abstract:: In eastern boundary current upwelling ecosystems, mesoscale circulation features such as eddies and upwelling filaments play a prominent role in the transfer of water and the associated plankton from the productive nearshore to the oligotrophic deep sea. The relationship between mesoscale circulation, zooplankton distributions, and the across-shelf transport of coastal...
