Fig. 2: Compositional shifts across peat depth after fire.

Post-fire shifts in the top five abundant classes within (a) archaeal and (b) bacterial communities. These classes were identified based on the harmonic mean of relative abundance and prevalence. Together, these classes represent approximately 68.8–81.64% of bacterial and 98.28–99.53% of archaeal communities, respectively. Mean relative abundances were computed from four independent biological replicates per group.
