Nitrosopumilus as main source of isoprenoid glycerol dialkyl glycerol tetraether lipids in the central Baltic Sea [PDF]
Nitrososphaeria in the phylum Crenarchaeota, is a widespread archaeal class in the oceanic realm, playing an important role in the marine carbon and nitrogen cycle.

Archaeosomes and Tetraether Lipid Liposome
Archaea have phytanyl ether lipids which is one of the characteristics that separates them from bacteria and eukaryotes. Some archaea have also unique membrane spanning tetrae- ther lipids (T EL); in Sulfolobus and Ihermoplasma species these TELmake up ...

Metabolic imprints in the hydrogen isotopes of Archaeoglobus fulgidus tetraether lipids
The stable hydrogen isotope composition of archaeal lipids is emerging as a potential paleoenvironmental proxy, adding to the well-established application of plant leaf wax-derived n-alkanes in paleohydrological reconstruction.

Freeze-fracture planes of methanogen membranes correlate with the content of tetraether lipids [PDF]
Methanospirillum hungatei GP1 contained 50% of its ether core lipids (polar lipids less head groups) as tetraether lipids, and its plasma membrane failed to fracture along its hydrophobic domain during freeze-etching. The membrane of Methanosaeta ("Methanothrix") concilii did not contain tetraether lipids and easily fractured to reveal typical ...

Planktonic Euryarchaeota are a significant source of archaeal tetraether lipids in the ocean [PDF]
Significance All three domains of life—Eukarya, Bacteria, and Archaea—are known to inhabit the marine water column from surface waters to great depth. Planktonic marine Archaea are comprised of two dominant groups—the Thaumarchaeaota and Euryarchaeota.

The influence of near-surface sediment hydrothermalism on the TEX86 tetraether-lipid-based proxy and a new correction for ocean bottom lipid overprinting [PDF]
The diversity and relative abundances of tetraether lipids produced by archaea and bacteria in soils and sediments are increasingly used to assess environmental change.

Transport of branched tetraether lipids from the Tagus River basin to the coastal ocean of the Portuguese margin: consequences for the interpretation of the MBT'/CBT paleothermometer [PDF]
Branched glycerol dialkyl glycerol tetraethers (brGDGTs), which are transported from soil to marine sediment by rivers, have been used to reconstruct the mean annual air temperature (MAAT) and soil pH of the drainage basin using the methylation index of ...
