16S rRNA gene sequencing with HiSeq2000 reveal the differences in prokaryotic diversity of samples from control and fire-impacted locations. (a) Communities clustered using principal coordinates analysis of the weighted UniFrac distance matrix. Each point corresponds to a sample colored in red/orange (○) for fire-impacted locations and in blue (◊) for the control locations. Lighter colors present the mineral soil depths. The percentage of variation explained by the plotted principal coordinates is indicated on the axes. (b) Contribution depth, fire and soil geochemistry on observed β-diversity was calculated via variation partitioning and represented as a Venn diagram. (c) Significant contributions of soil geochemistry to observed differences in prokaryotic diversity was tested using ANOVA.
