Latitudinal gradient of cyanobacterial diversity in tidal flats

Dissimilarity patterns revealed by PCoAs (a-c) and phylogenetic beta diversity (MPD) between paired samples according to their stabilization level (d). PCoAs were based on Jaccard (a) and Bray-Curtis (b) dissimilarity coefficients and the phylogenetic distance matrix (c) of all representative sequences per OTU (abundance unweighted); the first two axes explain a total variability of 24%, 23% and 39%, in a, b, and c respectively. (d) Kruskal-Wallis tests were performed to identify significant differences of phylogenetic beta diversity estimates (MPD) between samples that were grouped according to their stabilization levels.
