Understanding the processes that drive and regulate forest growth, biogeochemical cycles, biotic interactions and biodiversity-ecosystem functioning at different scales is of central importance to our work. Only with this understanding we can assess and predict shifts in the function of ecosystems and landscapes subjected to fundamental changes in the prevailing environmental conditions (i.e. climate and land use).
