Terrestrial ecosystems across the globe are being exposed to elevated atmospheric CO2, causing increase in temperatures and more frequent and intense drought and rainfall events. These changes have strong implications for biogeochemical cycling and the functioning of terrestrial ecosystems. Understanding the mechanisms controlling the response of plants and soil biota to climate change is therefore critical to predict potential feedbacks of terrestrial ecosystems to future climate scenarios.

The aim of this session is to bridge the knowledge of different disciplines to elucidate the multi-scale mechanisms and feedbacks underpinning the biogeochemical response to climate change, with emphasis on warming, drought and drying-rewetting dynamics. This session will give a broad overview of empirical and modelling studies across different scales, considering how climate change affects terrestrial biogeochemistry and the interactions between soil, microorganisms, plants and fauna. Attention will be given to the resistance or adaptation mechanisms of plants and soil biota during single or repeated environmental disturbances, as well as to the resilience and the associated temporal recovery dynamics after a disturbance. We will bring together researchers from different environments and create a discussion platform to review the current state-of-the-art, identify knowledge gaps, share ideas, and tackle new challenges in the field.
