A new study shows that future ecosystem functioning will increasingly depend on water availability. Using recent simulations from climate models, an international team of scientists found several “hot spot regions” where increasing water limitation strongly affects ecosystems. These include Central Europe, the Amazon, and western Russia.
The efficiency of plants to use water and take up carbon dioxide for growth critically depends on the availability of nitrogen, phosphorus and their balance in the ecosystem. In a recent study, researchers of the Max Planck Institute for Biogeochemistry and their Spanish partners analyzed how plants and their environment respond to the addition of these nutrients.
The Earth's Critical Zone is the thin, living, and permeable layer that connects the atmosphere with the geosphere. The Collaborative Research Centre 1076 aims at increasing our understanding of the links between surface and subsurface.
Lichens and mosses are rather inconspicuous plants. They grow on rocks, walls or tree trunks. Researchers of the University of Potsdam, the Max Planck Institute for Biogeochemistry Jena and the American Georgia Southern University have now discovered that these organisms absorb a significant part of the precipitation, which then evaporates directly…
Forests fulfil numerous important functions, and do so particularly well if they are rich in different species of trees. This is the result of a new study. In addition, forest managers do not have to decide on the provision of solely one service – such as wood production or nature conservation – as a second study demonstrates: several services…
Tanguro is situated in the southeast of Mato Grosso 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. Within the past two weeks both groups have worked hard to set up the new tower in a soybean field. This new tool complements the already existing two towers in the rainforest close-by.
Climate scientists have devised a simplified formula, based on models and observations, to describe one of the consequences of climate change: drought regions will continue to dry out in the future climate; those with a moist climate will experience additional rainfall. In short: dry gets drier; wet gets wetter (DDWW). In a recent study in Nature Geoscience published September 14th, this formula has been challenged by a team of climate researchers from ETH Zurich and MPI-BGC director Markus Reichstein.
Junior Professor Anke Hildebrand and Dr. Christine Fischer of Friedrich Schiller University in cooperation with the MPI for Biogeochemistry showed that the capacity for rainfall water uptake depends on the type of vegetation as well as on the presence of earthworms. The experimental study has been carried out at the Jena Experiment site in the floodplains of the Saale River which is technically serviced by the MPI for Biogeochemistry.
The CZO national workshop will take place in Jena with the objective to discuss the compartments of interest and the perspectives to establish a network of CZOs in Germany.
Based on his research on the reaction of ecosystems and their carbon and water cycles on climate change, M. Reichstein was nominated by Thuringian STIFT and ministries for the award.
