Behavior of juvenile bluefish Pomatomus saltatrix in vertical thermal gradients: influence of season, temperature acclimation and food

Creator:: Olla, Bori L., Studholme, Anne L., and Bejda, Allen J.
Abstract:: Behavioral responses of juvenile bluefish P. saltatrix L. exposed to cold water in a vertical thermal gradient were measured under controlled laboratory conditions. The temperature regime was similar to conditions that these fish encounter in their inshore and estuarine habitats along the Middle Atlantic coast. Measures included activity, schooling, position...

Factors driving Adélie penguin chick size, mass and condition at colonies of different sizes in the Southern Ross Sea

Creator:: Whitehead, Amy L., Lyver, Phil O'B., Ballard, Grant, Barton, Kerry, Karl, Brian J., Dugger, Katie M., Jennings, Scott, Lescroël, Amelie, Wilson, Peter R., and Ainley, David G.
Abstract:: Body size, mass and condition can affect an organism’s ability to cope with variation in resource availability or metabolic demand, particularly as juveniles reach independence. It follows that changes to parental provisioning efficiency (size and frequency of meals) through intraspecific competition or environmental conditions that affect prey availability may affect...

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,...

Prey dominance shapes trophic structure of the northern California Current pelagic food web: evidence from stable isotopes and diet analysis

Creator:: Miller, Todd W., Brodeur, Richard D., Rau, Greg, and Omori, Koji
Abstract:: Eastern boundary current (EBC) upwelling zones are among the most productive of marine ecosystems globally and have been generalized in terms of their food web structure. Little empirically based evidence exists to suggest that there is any one form of trophic control of EBC systems and, because of logistical constraints,...

Stage duration estimation for Calanus populations, a modelling study

Creator:: Miller, Charles B. and Tande, Kurt S.
Abstract:: Population dynamics of Calanus finmarchicus have been modelled using very finely divided representation of the stock according to age-within-stage, in the manner of models developed by C. S. Davis, A. Sciandra, F. Carlotti and others. A key assumption of the model is that development rate is relatively insensitive to food-limitation,...

What sets lower limits to phytoplankton stocks in high-nitrate, low-chlorophyll regions of the open ocean?

Creator:: Strom, Suzanne L., Miller, Charles B., and Frost, Bruce W.
Abstract:: Phytoplankton biomass in high-nitrate, low-chlorophyll (HNLC) ocean regions exhibits a pronounced stability: variation occurs only within a narrow range of values. The magnitude of this variation has profound ecological and geochemical consequences. While mechanisms believed to set the upper limits to HNLC phytoplankton biomass (iron limitation, microherbivore grazing) have received...

Role of Trichodesmium spp. in the productivity of the subtropical North Pacific Ocean

Creator:: Letelier, Ricardo M. and Karl, David M.
Abstract:: The concentrations of filamentous diazotroph Trichodesmium spp., present as free trichomes and in colonial assemblages, were measured at approximately monthly intervals at Stn ALOHA (22°45'N, 158°00'W) between October 1989 and December 1992. The average abundance of filaments in the upper 45 m of the water column was highly variable ranging...

Response of bacteria to simulated upwelling phytoplankton blooms

Creator:: Wetz, Michael S. and Wheeler, Patricia A.
Abstract:: Until recently, studies of the fate of primary production in coastal upwelling systems have focused mainly on export through sinking of particulate organic matter (POM). In week-long deck incubations conducted during the upwelling season off Oregon, a large accumulation of carbonrich (C:N ≥ 16) dissolved organic matter (DOM) occurred following...

Trophic cascades in the western Ross Sea, Antarctica: revisited

Creator:: Ainley, David G., Ballard, Grant, Jones, Randolph M., Jongsomjit, Dennis, Pierce, Stephen D., Smith, Walker O., Jr., and Veloz, Sam
Abstract:: We investigated mesopredator effects on prey availability in the Ross Sea, Antarctica, assessing the reasons why Adélie penguin Pygoscelis adeliae foraging trip duration (FTD) increases and diet changes from krill to fish as numbers of foraging penguins and competing cetaceans increase in the penguins’ foraging area. To investigate penguins’ seasonally...

Biogeochemical characterization of suspended particulate matter in the Columbia River estuary

Creator:: Prahl, Fredrick, Small, L. F., and Eversmeyer, B.
Abstract:: In order to understand what controls the composition of suspended particulate material (SPM) in estuarine turbidity maxima (ETM), a set of SPM samples collected in the Columbia River and estuary (northwestern USA) during 3 seasons (fall 1990, summer 1991, spring 1992) was analyzed for detrital mineral (Min), total organic matter...
