Revealing organic carbon sources fueling a coral reef food web in the Gulf of Mexico using stable isotopes and fatty acids
Revealing organic carbon sources coral reef food web Gulf of Mexico stable isotopes fatty acids
2014/4/2
Carbon and nitrogen stable isotopes and fatty acids (FAs) revealed primary producer organic carbon sources that fuel a coral reef food web with river influence. A stable isotope mixing model was used ...
Common carp (Cyprinus caprio) and European catfish (Sillurus glanis) from the Danube River as sources of fat soluble vitamins and fatty acids
RDI atherogenicity index (IA) thrombogenicity index (IT) HPLC GC-MS human health
2014/3/28
The total content of fat soluble vitamins and their percentages in the recommended daily intake for humans per 100 g portion, fatty acids composition, the atherogenic (IA) and thrombogenicity (IT) ind...
Trace metal cycling in the surface water of the South China Sea: Vertical fluxes, composition, and sources
Trace metal cycling the surface water the South China Sea: Vertical fluxes composition sources
2014/4/16
We deployed floating traps in the surface waters of the South China Sea on four occasions at depths of 30 m,100 m, and 160 m from 2006 to 2007 to quantify vertical metal fluxes in the surface water an...
Direct measurement of thed13 C signature of carbon respired by bacteria in lakes: Linkages to potential carbon sources, ecosystem baseline metabolism, andCO2fluxes
the d13 C signature bacteria in lakes potential carbon sources ecosystem baseline metabolism CO2 fluxes
2014/4/18
Using a novel method to measure the isotopic signature (d13C) of respiratory CO2 produced by bacterioplankton, we determined the proportion of terrigenous vs. algal-derived organic carbon (OC) respire...
Sources and sinks of dissolved phytochelatin in natural seawater
Sources and sinks dissolved phytochelatin natural seawater
2014/5/8
We modeled dissolved phytochelatin concentrations by studying its exudation from phytoplankton and its removal from seawater. Exudation rates were obtained from experiments in which a marine diatom, T...
Sources and cycling of carbonyl sulfide in the Sargasso Sea
Sources and cycling carbonyl sulfide Sargasso Sea
2014/5/14
The cycling of the radiatively important gas carbonyl sulfide (OCS) was studied in surface waters of the Sargasso Sea. In August 1999, surface OCS concentrations averaged 8.6 pmol L-1, showed minor di...
Autochthonous versus allochthonous carbon sources to bacteria: Results from whole-lake 13C addition experiments
Autochthonous allochthonous carbon sources bacteria whole-lake 13C
2014/5/14
Organic substrates for pelagic bacteria are derived from dissolved organic carbon (DOC) in the water column. DOC is a heterogeneous mixture of molecules, some of which are imported from the watershed ...
Relative importance of carbon sources for macroinvertebrates in a Rocky Mountain stream
Relative importance carbon sources macroinvertebrates Rocky Mountain stream
2014/5/27
Estimates of carbon sources, as determined from ratios of stable isotopes, were used in conjunction with estimates of secondary production to determine the relative contribution of algal carbon to mac...
Carbon sources for demersal fish in the western Seto Inland Sea, Japan, examined by d13C and d15N analyses
Carbon sources demersal fish the western Seto Inland Sea Japan examined by d13C d15N analyses
2014/5/27
The relative importance of benthic and pelagic primary production for demersal fish and some invertebrates in the western Seto Inland Sea of Japan was examined using carbon and nitrogen stable isotope...
Utilization of different nitrogen sources by the marine cyanobacteria Prochlorococcus and Synechococcus
different nitrogen sources marine cyanobacteria Prochlorococcus Synechococcus
2014/5/27
Prochlorococcus is the most abundant phytoplankter throughout the photic zone in stratified marine waters and experiences distinct gradients of light and nitrogen nutrition. Physiologically and geneti...

inorganic carbon photosynthesis a strain of Phaeodactylum tricornutum
2014/5/27
Diatoms are an important functional group of marine phytoplankton because of their role in the fixation of atmospheric carbon dioxide (CO2) and transfer of organic carbon to deep waters. Carbon-concen...
