In this study, a mangrove national nature reserve in Gaoqiao was selected to investigate the variations in SOC content, sub-component composition, and temperature sensitivity across mangrove communities. The underlying microbial mechanisms were elucidated using carbon-degrading enzyme assays, 16S rRNA sequencing, and metagenomic analysis. The results showed increased total SOC but decreased the ratios of labile to recalcitrant carbon and mineral-associated to particulate organic carbon in Rhizophoraceae forests compared to those in <em>Avicennia marina<\/em> and <em>Aegiceras corniculatum<\/em> community forests. The sediments of Rhizophoraceae forests also exhibited the lowest SOC mineralization rate yet the highest temperature sensitivity (Q10) of decomposition. The shift in SOC partitioning was accompanied by a transition of the microbial community toward K-strategist dominance, characterized by an increased ratio of K- to r-strategists, a higher ratio of recalcitrant-to-labile enzyme activity, and greater carbon allocation toward conservation versus reproduction. Multivariate modeling further revealed a significant linkage between SOC substrate (e.g., chemical recalcitrance and mineral protection) and microbial life-history strategies and functional traits, which in turn mediated SOC decomposition and Q10 across different mangrove communities. This study provides novel insights into the multi-stability of SOC in mangroves and the underlying ecological drivers, particularly under global warming.<\/p>\n","protected":false},"featured_media":5131,"template":"","meta":{"_acf_changed":false},"class_list":["post-5130","committee","type-committee","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.7 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Hao Cheng - Cognition Conferences<\/title>\n<meta name=\"description\" content=\"Hao Cheng obtained his PhD from Sun Yat-sen University.
