In order to measure inputs, cycling, and loss of material in aquatic ecosystems, a wide range of compounds and analytical tools is now available. Biological markers are compounds, or groups of compoun...
Identifying variable sea ice carbon contributions to the Arctic ecosystem: A case study using highly branched isoprenoid lipid biomarkers in Cumberland Sound ringed seals
Sea ice carbon The arctic ecosystem
2014/10/16
We analyzed liver samples from 322 ringed seals (Pusa hispida) collected from Cumberland Sound (southeast
Baffin Island) to test our ability to differentiate between carbon sources in near apex preda...
Cyanobacteria as a carbon source for zooplankton in eutrophic Lake Taihu, China, measured by 13C labeling and fatty acid biomarkers
Cyanobacteria carbon source zooplankton eutrophic Lake Taihu China measured by 13C labeling fatty acid biomarkers
2014/4/4
Using a combined stable-isotope and fatty-acid approach, we examined carbon-transfer routes from the cyanobacterium Microcystis to zooplankton in eutrophic Lake Taihu, China. Microcystis is generally ...

Diatom fatty acid biomarkers indicate recent growth rates in Antarctic krill
Diatom fatty acid biomarkers indicate growth rates Antarctic krill
2014/5/9
We investigated the relationship between nutritional condition (levels of specific fatty acids) and growth increment (percentage growth per intermoult period, percentage IMP-1) for Antarctic krill (Eu...
On the use of lipid biomarkers in marine food web analyses: An experimental case study on the Antarctic krill, Euphausia superba
lipid biomarkers marine food web analyses
2014/5/21
The application of marker fatty acids to trace the feeding habits of Euphausia superba (krill) has produced
contradictory results. We examined the effects of various diets on the fatty acid compositi...
Compound-specific D/H ratios of lipid biomarkers from sediments as a proxy for environmental and climatic conditions
Compound-specifi c environmental climatic conditions
2014/4/8
Hydrogen isotope ratios (D/H) of lipid biomarkers extracted from aquatic sediments were
measured to determine whether they can be used as a proxy for D/H of environmental water. Values of dD
were de...
