Extended Data Fig. 5: Decay model parameters for 6-month post-fire environment affinity incubation.
Coefficients for two-pool exponential decay models fit to soil C respiration data (R2 of models 0.98-1, P < 0.0001; n = 18 for unburned and moist soil burn cores, and n = 19 for dry soil burn cores). Fractional size of the fast (M1) and slow (M2) C pool (left two panels) and decay rate coefficients for the fast (k1) and slow (k2) C pool (right two panels) of the slow C pool following post-fire environment affinity incubation (autoclaving soil, inoculation with unburned microbial community, and 6-month incubation). For each boxplot, the central horizontal line indicates the median, the upper and lower bounds of the box indicate the inter-quartile range (IQR), the upper and lower whiskers reach the largest or smallest values within a maximum of 1.5 × IQR, and data beyond the whiskers are indicated as individual points.
