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 ...
Isotope enrichment in mangrove forests separates microphytobenthos anddetritus as carbon sources for animals
Isotope enrichment mangrove ests separates microphy tobenthos anddetritus carbon sources animals
<
2014/4/16
Microphytobenthos (MPB) and mangrove detritus were labeled with a carbonisotope (13C) in separate experiments to quantify their contributions to the nutrition of major faunal components within a mangr...
The impact of biogenic carbon sources on aerosol absorption in Mexico City

2009/3/13
In order to determine the wavelength dependence of fine (<1 micron) atmospheric aerosol absorption in the Mexico City area, the absorption Ångstrom exponents (AAEs) were calculated from hourly a...
Direct measurement of thed13 C signature of carbon respired by bacteria in lakes: Linkages to potential carbon sources, ecosystem baseline metabolism, andCO2fluxes

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...
Bacterial carbon sources in coastal sediments:a cross-system analysis based on stable isotope data of biomarkers
Bacterial carbon sources coastal sediments cross-system analysis stable isotope data
<
2010/1/13
Coastal ecosystems are typically highly productive, and the sediments in these systems receive organic matter from a variety of local and imported sources. To assess if general patterns are present in...

Carbon sources benthic mineralization mangrove adjacent seagrass sediments
<
2010/1/7
The origin of carbon substrates used by in situ sedimentary bacterial communities was investigated in an intertidal mangrove ecosystem and in adjacent seagrass beds in Gazi bay (Kenya) by δ13C analysi...
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 ...
