Macrofaunal modification of porewater advection: role of species function, species interaction, and kinetics

Creator:: Waldbusser, George G. and Marinelli, Roberta L.
Abstract:: ABSTRACT: Sedimentary habitats are complex associations of biotic, chemical, and physical processes comprising ‘ecosystem function’. The relative importance of these processes to biogeochemical cycling in highly reactive, permeable sediments remains poorly understood. We report results from several field experiments in a muddy-sand intertidal flat dominated by 2 functionally different types...

Invasive red lionfish Pterois volitans blow directed jets of water at prey fish

Creator:: Albins, Mark A. and Lyons, Patrick J.
Abstract:: Field and laboratory observations of feeding by invasive Pacific red lionfish Pterois volitans were conducted during June through August of 2008, 2009 and 2010 near Lee Stocking Island, Bahamas. Observations of this invasive marine predator revealed a previously undocumented piscivorous behavior. While slowly approaching prey fish, lionfish produce jets of...

Winter ichthyoplankton biomass as a predictor of early summer prey fields and survival of juvenile salmon in the northern California Current

Creator:: Daly, Elizabeth A., Auth, Toby D., Brodeur, Richard D., and Peterson, William T.
Abstract:: Diets of juvenile coho Oncorhynchus kisutch and Chinook O. tshawytscha salmon are made up primarily of winter-spawning fish taxa in the late-larval and early juvenile stages that are undersampled in plankton and larger trawl nets. Although we have no direct measure of the availability of fish prey important to juvenile...

Seasonal variation of male-type antennular setation in female Calanus finmarchicus

Creator:: Miller, Charles B., Crain, Jennifer A., and Marcus, Nancy H.
Abstract:: Female calanoid copepods of the family Calanidae can mature with either the juvenile and most typical female pattern of setation, termed trithek (T), or with the male pattern, termed quadrithek (Q). It was suggested by Fleminger (1985), but not proved, that females with the Q pattern have switched from development...

Environmental factors influencing larval walleye pollock Theragra chalcogramma feeding in Alaskan waters

Creator:: Porter, Steven M., Ciannelli, Lorenzo, Hillgruber, Nicola, Bailey, Kevin Mclean, Chan, Kung-Sik, Canino, Michael F., and Haldorson, Lew J.
Abstract:: This study examines potential interactions among the environmental variables likely to affect larval walleye pollock Theragra chalcogramma feeding in the sea. Walleye pollock larvae were sampled from Shelikof Strait, Gulf of Alaska, and from the eastern Bering Sea, with corresponding environmental data. Variables used in our study were time spent...

When is bigger better? Early marine residence of middle and upper Columbia River spring Chinook salmon

Creator:: Tomaro, Londi M., Teel, David J., Peterson, William T., and Miller, Jessica A.
Abstract:: Early ocean residence is considered a critical period for juvenile salmon although specific survival mechanisms are often unidentified and may vary by species or life stage. Columbia River spring-run Chinook salmon Oncorhynchus tshawytscha abundance has declined dramatically since the early 1900s. To elucidate mechanisms of early marine survival, we tested...

Summertime foraging ecology of North Atlantic right whales

Creator:: Baumgartner, Mark F. and Mate, Bruce R.
Abstract:: North Atlantic right whales were instrumented with suction-cup mounted, time-depth recorders (TDR) during the summers of 2000 and 2001 to examine their diving and foraging behavior. Simultaneous observations of temperature, salinity and the vertical distribution of their principal prey, Calanus finmarchicus stage 5 copepodites (C5), were obtained alon g each...

Fatty acid biomarkers in coldwater eelgrass meadows: elevated terrestrial input to the food web of age-0 Atlantic cod Gadus morhua

Creator:: Copeman, L. A., Parrish, C. C., Gregory, R. S., Jamieson, R. E., Wells, J., and Whiticar, M. J.
Abstract:: Lipid classes, fatty acids (FAs), and stable carbon isotopes of FAs were used to investi- gate dietary sources of organic carbon for juvenile Atlantic cod Gadus morhua during settlement into eelgrass Zostera marina . Primary producers, epibenthic prey, zooplankton, and fish were collected from August to November 2002 in shallow...

Comparison between environmental characteristics of larval bluefin tuna Thunnus thynnus habitat in the Gulf of Mexico and western Mediterranean Sea

Creator:: Muhling, Barbara A., Reglero, Patricia, Ciannelli, Lorenzo, Alvarez-Berastegui, Diego, Alemany, Francisco, Lamkin, John T., and Roffer, Mitchell A.
Abstract:: Despite being well adapted for feeding in cold water on their North Atlantic feeding grounds, Atlantic bluefin tuna undertake long migrations to reach warm, low productivity spawn - ing grounds in the Gulf of Mexico and Mediterranean Sea. Environmental conditions within spawning areas have been presumed to benefit larval survival,...

Proximity to multiple foraging habitats enhances seabirds’ resilience to local food shortages

Creator:: Paredes, Rosana, Harding, Ann M. A., Irons, David B., Roby, Daniel D., Suryan, Robert M., Orben, Rachael A., Renner, Heather, Young, Rebecca, and Kitaysky, Alexander
Abstract:: As central-place foragers, seabirds from colonies located close to multiple and/or productive marine habitats might experience increased foraging opportunities and enhanced resilience to food shortages. We tested whether this hypothesis might explain divergent trends in 3 populations of black-legged kittiwakes Rissa tridactyla, a surface-feeding piscivore, in the eastern Bering Sea....
