DFT Box-plot by Kingdom.
Box plots of DFT counts across the tree-of-life. Each box delineates lower quartile, median and upper quartile values. Most extreme values (whiskers) are within 1.5 times the inter-quartile range from the ends of the box. Outliers are also displayed. Prokaryotes are displayed twice. First divided according to bacteria and archaea, and secondly as mesophiles and thermophiles. P-values according to non-parametric two-sample Kolmogorov-Smirnov test are 2.5×10−2 (V-IV), 6.5×10−3(IV-P), 9×10−3 (P-F), 1.7×10−5 (F-B), 2.3×10−2(B-A) and 1.4×10−4 (M-T). Protista species show large variability and cannot be distinguished from Plantae or Fungi. Abbreviations: Vertebrates (V), Invertebrates (IV), Plantae (P), Fungi (F), Protista (PRT) Bacteria (B) Archaea (A), Mesophiles (M), Thermophiles (T).
