Fig. 3: Community composition of laboratory and field samples.

First two axes of non-metric multidimensional scaling (NMDS) ordination of Bray–Curtis99 dissimilarities for bacterial communities from lab study samples (24 h incubation, DNA only; 5-week incubation; 6-month autoclaved post-fire-affinity incubation) and field samples (1 and 5 yr post-fire) (n = 412 samples; k = 3, stress = 0.13).
