FIG 2.
Relative abundances of genera present in soil samples from low to high special Antarctic blend (SAB) diesel fuel concentration. Samples are sorted according to SAB fuel concentration within each soil plot and are labeled according to fuel category (control, low, medium, and high). The log SAB fuel concentration is on a scale of 0 to 4.5, with 4.5 ∼ 31,000 mg kg−1. Representative operational taxonomic units (OTUs) that were unable to be reliably classified to the genus level were listed with the closest classification level.
