Figure 3

Microbial community diversity and species differences. (A) Shannon and (B) Chao1 alpha diversity indices of the bacterial communities. (C) PCoA of the bacterial community composition at the phylum level and (D) KEGG level 3 based on Bray-Curtis distance (p < 0.01). (E) Wilcoxon rank-sum test of the top 15 bacteria at the genus level and (F) the three bacteria with the highest difference in abundance. QDP, RZP and HYP represent phycospheric seawater microorganisms (PSM), QDN, RZN and HYN represent nonalage-covered seawater microorganisms (NSM). p < 0.05 *, p < 0.01 **, p < 0.001 ***.
