Glycerol dialkyl glycerol tetraether (GDGT) lipids are membrane lipids which were long
thought to be synthesized mainly by archaea, organisms thought to be limited to extreme …

The response of the terrestrial biosphere to warming remains one of the most poorly
understood and quantified aspects of the climate system. One way to test the behavior of the …

Microbial lipid biomarkers preserved in geological archives can be used to explore past
climate changes. Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are unique …

Despite widespread use of branched glycerol dialkyl glycerol tetraethers (brGDGTs) for
paleo-temperature reconstruction, no global calibration for their application in lakes has …

The development of methods using liquid chromatography coupled to mass spectrometry to
analyze glycerol dialkyl glycerol tetraethers (GDGTs) has substantially expanded the …

The distribution of branched glycerol dialkyl glycerol tetraethers (brGDGTs) in soils has been
shown to correlate with the soil pH and the mean annual air temperature (MAT). This has …

Glycerol dibiphytanyl glycerol tetraethers (GDGTs) are archaeal monolayer membrane lipids
that can provide a competitive advantage in extreme environments. Here, we identify a …

The early Eocene (56 to 48 million years ago) is inferred to have been the most recent time
that Earth's atmospheric CO2 concentrations exceeded 1000 ppm. Global mean …

The MBT–CBT proxy for the reconstruction of paleotemperatures and past soil pH is based
on the distribution of branched glycerol dialkyl glycerol tetraether (brGDGT) membrane …

Accurate temperature records for the deep geological past are a vital component of
paleoclimate research. Distributional changes of branched glycerol dialkyl glycerol …
