The better understanding of the processes driving the dynamics of forest ecosystems requires the documentation of the constantly interacting compartments and fluxes of the biogeochemical cycle. Scientists study two fluxes (deposition of nutrients through precipitation and litterfall) and two compartments (foliage and ground vegetation).

Unser Klima wird wärmer, vor allem im Winter. Die Wintertemperaturen sind in den letzten Jahrzehnten vielerorts doppelt so stark angestiegen wie diejenigen im Sommer. Die Schneeschmelze in den Bergen findet deshalb immer früher statt. Können die Pflanzen den längeren Sommer für Wachstum nutzen? Verändert sich dadurch die Vegetation?

The fine roots of forest trees are the actual interface between the soil solution and plants. What is the influence of environmental changes on the rooted area of forest trees and the condition of mycorrhizas?

Scientists investigate the reactions of fine roots of spruce and poplar to enhanced heavy metal contents in the soil. They measure growth and architecture of newly derived fine roots of these trees and investigate mycorrhizas of birches in order to localise and quantify the heavy metals on a subcellular level.
