Permutational multivariate analysis results based on the mean Bray–Curtis dissimilarities per Time point and Control-Spike experimental group depicted for total community, prokaryotic, protozoan and fungal/metazoan rRNA contigs. P-values < 0.05 were consider ed significant with * P < 0.05, **P < 0.01, and ***P < 0.005. Nonsignificant (NS) categories and pair-wise contrasts in time points were removed for the Control-Spike test.
