Journal ArticleDOI
Distributional variations in marine crenarchaeotal membrane lipids: a new tool for reconstructing ancient sea water temperatures?
TL;DR: In this article, a significant linear correlation was found between the number of cyclopentane rings in sedimentary membrane lipids derived from marine crenarchaota and the annual mean sea surface temperatures, suggesting that the mechanism of physical adaptation of their membrane compositions to temperature is identical to that of their thermophilic relatives.
Journal ArticleDOI
A novel proxy for terrestrial organic matter in sediments based on branched and isoprenoid tetraether lipids
Ellen C. Hopmans,Johan W.H. Weijers,Enno Schefuß,Lydie Herfort,Jaap S. Sinninghe Damsté,Stefan Schouten +5 more
TL;DR: In this paper, a tracer for terrestrial organic carbon in sediments based on the analysis of tetraether lipids using high-performance liquid chromatography/mass spectrometry (HPLC/MS) was proposed.
Journal ArticleDOI
Abundance and diversity of denitrifying and anammox bacteria in seasonally hypoxic and sulfidic sediments of the saline lake Grevelingen
Yvonne A. Lipsewers,Ellen C. Hopmans,Filip J. R. Meysman,Jaap S. Sinninghe Damsté,Laura Villanueva +4 more
TL;DR: The simultaneous presence and activity of organoheterotrophic Denitrifying bacteria, sulfide-dependent denitrifiers, and anammox bacteria suggests a tight network of bacteria coupling carbon-, nitrogen-, and sulfur cycling in Lake Grevelingen sediments.
Journal ArticleDOI
The organic geochemistry of glycerol dialkyl glycerol tetraether lipids: A review
TL;DR: Progress made over the last decade in the analysis, occurrence and recognition of sources of GDGTs, their applications as biomarker lipids, and the development and application of proxies based on their distributions are reviewed.
Journal ArticleDOI
Environmental controls on bacterial tetraether membrane lipid distribution in soils
Johan W.H. Weijers,Stefan Schouten,Jurgen C. van den Donker,Ellen C. Hopmans,Jaap S. Sinninghe Damsté +4 more
TL;DR: In this paper, the relative distribution of soil-derived GDGT membrane lipids can be used in palaeoenvironmental studies to estimate past annual mean air temperature and soil pH.
