Vertical diversity and association pattern of total, abundant and rare microbial communities in deep-sea sediments.

ABSTRACT: Microbial abundance and community composition in marine sediments have been widely explored. However, high-resolution vertical changes of benthic microbial diversity and co-occurrence patterns are poorly described. The ecological contributions of abundant and rare species in sediments also remain largely unknown. Here, by analysing microbial populations at 14 depth layers of 10 subseafloor sediment cores (water depth 1,250-3,530 m) obtained in the South China Sea, we provided the vertical profiles of microbial β-diversity and co-occurrence influenced by subcommunities of different abundance. These 134 sediment samples were clustered into four groups according to sediment depth (1-2, 6-10, 30-90 and 190-790 cm) with obvious shifts in microbial community compositions.
