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...
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...
