Plant traits extend Earth observations to the level of individual organisms, providing a critical link between biodiversity, ecosystem functioning, and biogeochemical modeling under rapid global change. However, bridging the temporal and spatial mismatches between plant trait data and biogeochemical cycles remains a major challenge.

This session addresses the role of plant traits, biodiversity, acclimation, and adaptation in regulating the biogeochemical cycles of water, carbon, nitrogen, phosphorus, and sulfur across scales. We welcome conceptual, observational, experimental, and modeling studies from local to global levels, including in situ and remote sensing approaches.
