Fig. 1From: Microbial succession during the transition from active to inactive stages of deep-sea hydrothermal vent sulfide chimneysTaxonomic composition of microbial communities from the active L-vent chimney (a) and recently inactive M-vent chimney (b). Numbers in the pie charts represent percentages of each taxonomic unit in class level, which are estimated based on the full-length 16S rRNA genes retrieved from the two metagenomes.
