Abstract The global asymmetry in the floristic diversity distribution within mangrove ecosystems is well-documented.

Mangrove forests, found primarily in tropical and subtropical coastal regions, support diverse microbial communities that are crucial for nutrient cycling energy flow then sustain mangrove ecosystem integrity. This study investigated the seasonal dynamics of bacterial sediments Shupaisha island (Zhejiang Province, China) through amplifying high-throughput sequencing 16S rRNA gene fragments. Proteobacteria (23.59-44.40%), Actinobacteria (4.92-19.01%), Bacteroidetes (4.31-22.79%) dominated phyla with highest diversity indices winter. were more abundant during winter (13.27%) spring (14.36%), while abundance was summer, significantly correlating temperature. Significant differences community composition observed between autumn exhibited similar distribution, indicating a transitional pattern dynamics, temperature sand content being most influential factors. enhances our understanding characteristics ecosystems, potentially providing valuable insights into monitoring assessing health stability ecosystems Zhejiang Province.
