Results of all significant contrasts.

<p>Contrasts were performed for significant main and interaction effects for each linear mixed model or Permutational multivariate analysis of variance (PERMANOVA) analysis, and were all compiled and presented here. Under each analysis heading are the significant main or interaction effects identified in the global test for that analysis, that describe the effect, the contrasts, and correction for significance. Under each significant effect are the null hypotheses (H<sub>0</sub>) for the relevant contrasts, and for each contrast, either a pseudo-F or a chi square statistic, the degrees of freedom for the test, the statistic, and the p-value. Contrasts were evaluated using Type III sums of squares with Bonferroni corrections applied to significance levels for each set of contrasts evaluated for each analysis. For contrasts involving fire regime, litter load, or their interaction, a significance level of α = 0.01 was used; for contrasts involving effects over time, α = 0.0033 was used to account for the multiple analyses.
