Peatlands are critical in global biogeochemical and water cycles and serve as buffers against environmental change. However, the dirction of their feedbacks to the Earth system remain uncertain under rising natural and anthropogenic stressors. This session seeks to improve prediction of peatland responses to disturbances-environmental extremes, hydrological changes, land-use change, and restoration. We invite contributions on mechanistic processes, ecosystem stocks and fluxes, and feedbacks across scales, including experimental manipulations, long-term observational networks, natural gradients, or post-restoration assessments. Submissions integrating empirical data with models to forecast biogeochemical, hydrological, nutrient, and biotic trajectories are especially welcome. Topics include, but are not limited to:• Trace gas fluxes, net ecosystem exchange, decomposition, and respiration• Vegetation dynamics, moss turnover, and succession• Microbial community structure and function• Porewater chemistry and nutrient cycling under disturbance or restoration• Predictive modeling and data assimilation for peatland futures
