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...
Copepod reproduction is unaffected by diatom aldehydes or lipid composition
Copepod reproduction unaffected diatom aldehydes lipid composition
2014/4/21
We investigated whether reduced reproductive success of copepods fed with diatoms was related to nutritional imbalances with regard to essential lipids or to the production of inhibitory aldehydes. In...
Sources and transport of terrestrial organic matter in Vancouver Island fjords and the Vancouver–Washington Margin: A multiproxy approach usingd13Corg, lignin phenols, and the ether lipid BIT index

2014/4/21
The Branched and Isoprenoid Tetraether (BIT) index (a ratio of marine and terrestrial glycerol dialkyl glycerol tetraether [GDGT] membrane lipids) was recently introduced as a proxy for the fraction o...

D-H fractionation in Sporomusa ORIGINAL ARTICLE Blackwell Publishing, Ltd. Hydrogen isotope fractionation during H2 /CO2 acetogenesis: hydrogen utilization efficiency and the origin of lipid-bound hydrogen
ORIGINAL ARTICLE D-H fractionation
2014/4/8
Hydrogen metabolism was studied in the anaerobic bacterium, Sporomusa sp. strain DMG 58, by measuring
natural abundance levels of deuterium in H2
, H2O, and individual fatty acids during acetogenic ...
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...
