英文摘要	AimsSoil organic carbon (SOC) stability greatly affects soil carbon sequestration capacity and carbon emissions, is related to soil bacterial communities, but it remains unclear whether such relationships exist in alpine wetland biogeomorphic succession.MethodsHere, we used a space-for-time approach across hydrological gradients, and alpine wetland succession can be divided into three types: Swamp (S), Swamp Meadow (SM), and Meadow (M) to examine the dynamics change of SOC fractions and bacterial communities.ResultsThe succession from S-SM-M resulted in decreased SOC stability (SM and M decreased by 18.65% and 31.88% compared to S). Furthermore, the decrease in SOC stability was primarily due to the decrease in soil moisture during succession and moisture-induced changes in bacterial community structure. e.g., the relative abundance of Proteobacteria decreased significantly by 40.99% and 52.87% in SM and M, while the relative abundance of Acidobacteria increased by 43.49% and 185.04% in SM and M compared to S. Co-occurrence network and random forest analyses further identified that changes in keystone taxa of bacteria, including Deltaproteobacteria, Acidimicrobiia, Bacteroidia and Gammaproteobacteria, were associated with SOC stability.ConclusionsIn conclusion, bacteria shifted their community composition to reduce SOC stability in response to soil moisture variations during succession, and underscores the importance of identifying keystone taxa that are crucial for maintaining SOC stability.
