Coastal vegetated ecosystems such as salt marshes, seagrass meadows, and mangroves play a critical role in regulating greenhouse gas (GHG) fluxes, yet their functioning under future environmental change remains poorly understood. This session invites contributions that experimentally investigate how multiple, co-occurring stressors—such as warming, eutrophication, acidification, hypoxia, and salinity changes—affect the structure and function of coastal vegetated habitats, with a specific focus on CO₂, CH₄, and N₂O fluxes.

We welcome experimental studies—conducted in laboratory, mesocosm, or field settings—that explore the mechanistic responses of coastal vegetation and associated microbial communities to interacting stressors. Of particular interest are studies that assess whether stressor effects are synergistic, antagonistic, or additive in altering GHG fluxes. In addition, we strongly encourage contributions that integrate experimental results with modeling approaches, including empirical or process-based models, to extrapolate findings across spatial and temporal scales or to predict ecosystem responses under future climate scenarios.

By highlighting both experimental and modeling work, this session aims to foster interdisciplinary dialogue and synthesis across biogeochemistry, plant physiology, and microbial ecology, and to advance our ability to forecast the resilience and climate regulation potential of coastal vegetated ecosystems in a changing world.
