DFT Box-plot by Kingdom. PersiErez HornDavid 2013 <p>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. <i>P</i>-values according to non-parametric two-sample Kolmogorov-Smirnov test are 2.5×10<sup>−2</sup> (V-IV), 6.5×10<sup>−3</sup>(IV-P), 9×10<sup>−3</sup> (P-F), 1.7×10<sup>−5</sup> (F-B), 2.3×10<sup>−2</sup>(B-A) and 1.4×10<sup>−4</sup> (M-T). Protista species show large variability and cannot be distinguished from Plantae or Fungi.
