英文摘要	Coastal areas are land-sea transitional zones with complex natural and anthropogenic disturbances. Microorganisms in coastal sediments adapt to such disturbances both individually and as a community. The microbial community structure changes spatially and temporally under environmental stress. In this study, we investigated the microbial community structure in the sediments of Hangzhou Bay, a seriously polluted bay in China. In order to identify the roles and contribution of all microbial taxa, we set thresholds as 0.1% for rare taxa and 1% for abundant taxa, and classified all operational taxonomic units into six exclusive categories based on their abundance. The results showed that the key taxa in differentiating the communities are abundant taxa (AT), conditionally abundant taxa (CAT), and conditionally rare or abundant taxa (CRAT). A large population in conditionally rare taxa (CRT) made this category collectively significant in differentiating the communities. Both bacteria and archaea demonstrated a distance decay pattern of community similarity in the bay, and this pattern was strengthened by rare taxa, CRT and CRAT, but weakened by AT and CAT. This implied that the low abundance taxa were more deterministically distributed, while the high abundance taxa were more ubiquitously distributed.Based on a full-scale microbial taxa classification, the roles and contributions of key taxonomic categories in maintaining and altering microbial community structures in the sediments of Hangzhou Bay were recognized.Based on a full-scale microbial taxa classification, the roles and contributions of key taxonomic categories in maintaining and altering microbial community structures in the sediments of Hangzhou Bay were recognized.; National Natural Science Foundation of China [51178002]; SCI(E); PubMed; ARTICLE; dhwen@pku.edu.cn; 10; 92
