Fossilized lipids preserved in sedimentary rocks offer singular insights into the Earth's
palaeobiology. These 'biomarkers' encode information pertaining to the oxygenation of the …

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 …

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 …

Hydrogen-isotopic abundances of lipid biomarkers are emerging as important proxies in the
study of ancient environments and ecosystems. A decade ago, pioneering studies made use …

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

Acidobacteria are ubiquitous and abundant members of soil bacterial communities.
However, an ecological understanding of this important phylum has remained elusive …

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 …
