Spreadsheet of summarized results.

Compilation of all analyses on fungal and bacterial communities. Each hypothesis is listed with the corresponding effect tested in each analysis. For the nonmetric multidimensional scaling (NMDS) analysis, visible separation is indicated with the corresponding figure or supplementary file that shows the community patterns for that particular effect. For the Permutational Multivariate Analysis of Variance (PERMANOVA) analysis, indications are provided if the tested effect, corresponding to its specific hypothesis, was found to be significant in the global PERMANOVA test on fungal or bacterial community compositions. For the alpha diversity metrics of richness, evenness, and Shannon diversity, indications are provided if the tested effect, corresponding to its specific hypothesis, was found to be significant in the Analysis of Variance (ANOVA) test of the linear model on a particular metric. For all PERMANOVA and ANOVA tests, contrasts were performed on significant effects identified in the global test, and indications are provided where the corresponding contrasts were significant. For effects in the global test that were not significant, contrasts were not performed. A significance level of α = 0.01 was used for all PERMANOVA and ANOVA tests, and for all contrasts involving fire regime, litter load, or their interaction. A significance level of α = 0.0033 was used for all contrasts involving effects over time to account for the multiple analyses. Red and bolded font indicate significant effects in each respective test.
