Phyla with abundance <1% were grouped together. Results from mixed-effects models analyses are shown. Significance was determined using ANOVA. For each phylum, we report the relevant F statistic and degrees of freedom (F5,20) and significance (P(>F)). Letters indicate significant differences between time points (Tukey HSD test). Degrees of freedom were constant across all tests.
