Certain taxa from both abundant and rare populations varied rapidly in their 16S rRNA levels in response to tidal cycling. The observation of rRNA accumulation in response to drying and rewetting was used to divide the microbial community structure into 'early responders' (within 3 h of dry-down or wet-up) and 'delayed responders' (3+ h after wet-up). Response patterns were phylogenetically constrained across supra- to subtidal zones across all tidal stages. Microbial iron- and sulfur-cycling networks included these rare but active taxa, illustrating their spatiotemporal complexity, which should be considered for an accurate assessment of bioremediation efficiency, and specially for validating predictive biogeochemical models of long-term CASS ecosystems.]]> Fri 21 Jan 2022 12:35:02 AEDT ]]>
