Spatial Fingerprints of Climate Extremes: Impacts on ecosystem processes, vegetation function and biodiversity
Session ID#: 249413
Session Description:
As climate extremes intensify in frequency and severity, terrestrial ecosystems are undergoing unprecedented structural and functional transformations. These disturbances disrupt the coupled carbon–water–energy cycles and drive shifts in vegetation structure, species distributions, and biodiversity patterns. The spatial fingerprints of these changes are often most pronounced at latitudinal and altitudinal margins, where ecosystems and species are pushed beyond their physiological thresholds. This session invites observational, experimental, and modeling studies that explore ecosystem responses to extreme climate events and assess their impacts on landscape dynamics, habitat quality, biodiversity, and ecosystem services. We encourage submissions that use multi-disciplinary, multi-scale approaches, combining observational data, remote sensing, and ecosystem modeling to enhance our understanding of how climate extremes are reshaping terrestrial ecosystems and their role in the global carbon, water and energy cycles.
