Time-resolved microbial guild responses to tidal cycling in a coastal acid-sulfate system

Abstract

Environmental context Microbes play key roles in controlling acidification and metal toxicity in coastal acid-sulfate soils. We characterised the time-dependent metabolic activities of abundant and rare taxa in acidifying tidal wetlands and showed that rare taxa exhibiting higher activity may exert significant influence on iron- and sulfur-cycling. Our findings yield new insights into the drivers and timing of iron- and sulfur-cycling in coastal acid-sulfate systems. Abstract Tidal inundation has been trialled as a remediation strategy for coastal acid-sulfate soil (CASS) environments. Microbial community structure and activity are hypothesised to play key roles in this process, but remain p..
