Methane cycling microorganisms drive seasonal variation of methane emission in mangrove ecosystems.

ABSTRACT: Coastal mangroves are one of the significant hotspots of natural methane (CH₄) emissions, yet the seasonal dynamics of these emissions and the underlying microbial drivers remain poorly understood. A clearer understanding of these processes is critical for predicting and mitigating methane emissions from these crucial ecosystems. In this study, we conducted a seasonal investigation (from March 2021 to January 2022) in mangrove sediments of the Futian Natural Reserve. We measured in situ methane fluxes and analyzed the microbial community structure via 16S rRNA gene sequencing, metagenomics and metatranscriptomics. Our results revealed significant seasonal variations in methane emissions, with the highest rates occurring in summer. Based on relative abundance of 16S rRNA gene amp
