Effects of seaweed cultivation on the alpha-diversity indexes. The observed number of OTUs based on 18S (A) and 16S (D), the Shannon index based on 18S (B) and 16S (E), and the Chao1 index based on 18S (C) and 16S (F) shows the alpha diversity of microbial communities across different cultivation periods at the three study sites. Different letters (a, b) represent significant differences (p-value < 0.05) in mean value among zones C, P, and G by ANOVA.
