Relative contribution of microbial input sources to the samples biomass in the four hydrothermal regimes, inferred from the presence (µg·g⁻¹ of dry weight) of lipid biomarkers of (a) bacteria (sum of n-fatty acids from 16:0 to 18:0;⁵⁸); (b) cyanobacteria (sum of n-heptadecane, isomeric n-heptadecenes, and monomethylalkanes of C₁₇, C₁₈ and C₁₉^59–62; diploptene⁶³; and 16:1ω7, 18:2ω6, and 18:3ω6 fatty acids^62,64,65); (c) photosynthetic sulfur and non-sulfur bacteria or PhSnSB (sum of the n-alkanols C₁₆, C₁₇, and C₁₈⁶⁶); (d) sulfate-reducing bacteria or SRB (sum of phytane⁶⁷; i/a-pairs of 15:0, 17:0, and 15:1 fatty acids³⁵; and 16:1ω5, 17:1, and 18:1ω5 fatty acids^35,68,69); (e) archaea (squalane^70,71); and (f) thermophiles (sum of dicarboxylic acids;⁷²).
