Fig. 6: Discrimination for the β diversity.

a Eukaryotic algae. b Protozoa. c Fungi. d Animalia. e Bacteria. f Cyanobacteria. Ordination plots of community structure based on Bray-Curtis dissimilarity matrices. Significant differences were studied by Adonis with the Monte Carlo 999 permutations test; the close dots in the ordination space indicate that each shares a larger percentage of taxa with the other. Boxplots showing the pairwise comparison of the dissimilarity of community structure among the three periods. significant differences were investigated using the one-way ANOVA followed by post-hoc Bonferroni test. *P < 0.5; **P < 0.01; ***P < 0.001.
