The phylum Acidobacteria is one of the most widespread and abundant on the planet, yet
remarkably our knowledge of the role of these diverse organisms in the functioning of …

The cytoplasmic membrane of a prokaryotic cell consists of a lipid bilayer or a monolayer
that shields the cellular content from the environment. In addition, the membrane contains …

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 …

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 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 …

The early Eocene (56 to 48 million years ago) is inferred to have been the most recent time
that Earth's atmospheric CO 2 concentrations exceeded 1000 ppm. Global mean …

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

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 …

Molecular organic geochemical proxies are increasingly being utilized to reconstruct past
environmental conditions as new tools continue to be discovered and developed. To date …
