英文摘要Blue carbon ecosystems (BCEs) serve as both carbon sinks and sources, with carbon release from sediments as greenhouse gases (GHGs) potentially reducing their overall sequestration benefits. However, the mechanisms driving microbial community succession processes in sediments, which influence GHG production in BCEs, remain uncertain. We collected 129 sediment samples from diverse BCEs (mudflats, mangroves, salt marshes, and seagrasses) across a broad latitude gradient (18 degrees N - 41 degrees N) in China. Using microcosm incubation, amplicon sequencing, and qPCR, we investigated latitudinal patterns of microbial-mediated GHG production capacities and underlying driving mechanisms. Results showed that mangrove and salt marsh sediments, with higher microbial alpha diversity and abundance, had a greater GHG production capacity than mudflat and seagrass. The global warming potential of salt marsh sediments significantly (p < 0.05) decreased with latitude. Distance-decay relationships suggested that vegetation enhances sediment microbial community stability in BCEs. Microbial co-occurrence networks showed that microbial interactions were not a potentially vital biotic factor influencing the GHG production capacity. Latitudinal patterns of the GHG production potential were shaped by microbial abundance due to the functional stability of GHG production within BCE sediments, which was mainly driven by dispersal limitations. This study highlights the role of microbial abundance in shaping GHG production patterns in BCE sediments across broad geographic scales.
