Abstract Coastal blue carbon (C) ecosystems are recognized as efficient natural C sinks and play key roles in mitigating global climate change. Microbially driven C, nitrogen (N) sulphur (S) cycles crucial for ecosystem functioning, but how microorganisms drive sink formation sequestration coastal sediments remains unclear. In this study, we conducted a comprehensive analysis of amino sugars, N S cycling genes/pathways their associated taxa native ( Cyperus malaccensis Kandelia obovata ) alien Spartina alterniflora Sonneratia apetala vegetation. Compared to the alien‐vegetated sediment, native‐vegetated sediment had significantly p < 0.05) higher microbial necromass functional potentials chemoautotrophic fixation, degradation, methane cycling, 2 oxidation sulphate reduction. Also, our microbiomes showed that could be coupled with fixation and/or nitrate/nitrite oxidation, degradation were found pathways predicting C. Additionally, sulphur‐oxidizing Burkholderiales metagenome‐assembled genomes (MAGs) group dominated sediments. These results suggested oxidizers, particular novel lineage, might dominates through anabolism (C fixation);the coupling microbially processes; deposition derived This study provides insights into importance oxidizers shed new light on mechanism ecosystems, which also has important implications enhancing wetlands.

Shifts in agricultural land use over the past 200 years have led to a loss of nearly 50% existing wetlands USA, and activities contribute up 65% nutrients that reach Mississippi River Basin, directly contributing biological disasters such as hypoxic Gulf Mexico "Dead" Zone. Federal efforts construct restore wetland habitats been employed mitigate detrimental effects eutrophication, with an emphasis on restoration ecosystem services nutrient cycling retention. Soil microbial assemblages drive biogeochemical cycles offer unique sensitive framework for accurate evaluation, restoration, management services. The purpose this study was elucidate patterns soil bacteria within among by developing diversity profiles from high-throughput sequencing data, link functional gene copy number nitrogen genes measured flux rates collected flow-through incubation cores, predict using assemblage composition. showed fine-scale turnover cores across topsoil horizon (0-5 cm; top vs bottom partitions) were structured practices easements (tree planting, shallow water, remnant forest). Connections between composition, number, show potential bacterial be used bioindicators landscape. In addition, predictive accuracy improved when implementing deep learning models paired connected samples time.
