Coupling of biogeochemical cycles with functional processes in ecosystems

The Department of Biogeochemical Processes explores the key processes and organisms that regulate exchanges of energy, water and elements between ecosystems and their surroundings, and how those processes are affected by climate variation and land management.

Selected projects

Tree Assimilation and Carbon Allocation Physiology Experiment (TACAPE): A joint project with the Brazilian Institute for Amazon Research (INPA) to manipulate the carbon use efficiency of tropical forest.
The Jena Experiment explores the role of biodiversity in element cycling and trophic interactions in a grassland community.
The Jena Drought Stress Experiment investigates mechanisms in drought-induced tree mortality with a particular emphasis on the interplay between the tree water and carbon cycle.
The project for measuring the Age of CO₂ emitted from tree stems investigates the role of storage carbon pools as sources for respiration in trees under different environmental conditions.
The QUASOM field experiment addressing stabilization or mobilization of carbon in soils - in collaboration with the Biogeochemical Model-Data Integration group.
TRY database - the functional diversity of plants.

Lake Tangra Yumco in Tibet (Picture author: Roman Witt)

Measurement tower in Tanguro, Brazil. The soybean field is located at the border of the Amazon rainforest, a region particularly threatened by deforestation, forest fires and climate change. Intensive land use in this area exerts a great influence on the vegetation, the water and the nutrient availability. (Picture author: Martin Hertel)
