Fig. 1: Surface soil microbiome undergoes homogenizing effect with burn.
From: Wildfire-dependent changes in soil microbiome diversity and function
a–d, NMDS of surface (0–5 cm) (a,c) and deeper (5–10 cm) soil (b,d) bacterial (a,b) and fungal (c,d) communities shows increased separation of burned and unburned microbial communities in surface soils relative to deep soil communities. e,f, Shannon’s diversity (H) calculated from 16S rRNA and ITS gene sequencing in surface (e) and deep soils (f) further shows the increased susceptibility of microbiomes in surface soils to wildfire. Asterisks in e and f denote significant differences (pairwise t-test; P < 0.05) between conditions (n = 16 for control S and D, n = 24 for low, moderate and high severity-impacted S and D samples). Corresponding P values are listed in Supplementary Table 1. The lower and upper hinges of the boxplots represent the 25th and 75th percentiles, respectively, and the middle line is the median. The whiskers extend from the median by 1.5× the interquartile range. Data points represent outliers.
