Diversity and coexistence in GS and FSS populations pre- and postsimulation. (A) Estimated diversity and coexistence pre- and postsimulation for the whole (23 isolates) and the DNase-producing (13 isolates) population using a probabilistic cellular automaton (ProbCA) and the interaction matrices (Tables S3-1 to S3-3). The forest subsurface (FSS₂₃) population was composed of 23 isolates, and the grassland surface (GS₂₃) population was composed of the 23 best-surviving isolates selected after a pilot run with the full data set. Coexistence is the number of isolates present in the dynamic equilibrium. Shannon diversity was based on the resulting isolate distribution after simulation. Error bars represent the SEM (n = 100). SEMs in the GS₁₃ and FSS₁₃ populations were too small to show. (B) Interaction types and relative abundances of exDNase-producing isolates pre- and postsimulation in the 23-strain and 13-exDNase-producing-strain-only matrices. *, heteroscedastic t test; all others were homoscedastic.
