a Relative abundances of various bacterial IPLs, as based on their structural linkages. Note the dominance of ether lipids within serpentinite mud. b Relative abundances of various bacterial IPLs based on their head groups. Glycosidic lipids dominate within serpentinite mud. c Absolute concentrations of bacterial IPLs showing an increase in bacterial IPL concentrations within serpentinite mud. cmbsf cm below seafloor, DEG dietherglycerol, IPL intact polar lipid.
