Zur COP27 in Ägypten reisten auch neun Max-Planck-Wissenschaftlerinnen und -Wissenschaftler, unter Ihnen Dr. Carlos Sierra, Gruppenleiter am Max-Planck-Institut für Biogeochemie in Jena. Im Interview vermittelt Tom Sparks Eindrücke und Einschätzungen zur Rolle der Wissenschaft.
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.
Microorganisms in aquifers deep below the earth’s surface produce similar amounts of biomass as those in some marine waters. This is the finding of researchers led by the Friedrich Schiller University Jena and the German Centre for Integrative Biodiversity Research (iDiv). The study has been published in Nature Geoscience.
You can't see them with the naked eye, but our forest ground is littered with microorganisms. They decompose falling leaves, thereby improving soil quality and counteracting climate change. But how do these single-celled organisms coordinate their tasks? An international research team has been looking into this little-understood process. The results of the study were recently published in Scientific Reports.
International researchers found a pattern of extreme climate conditions leading to forest dieback. To do this, the team had collected worldwide records of climate-related tree and forest dieback events over the past nearly five decades. The results, recently published in Nature Communications, reveal an ominous scenario for forests in the context of ongoing global warming.
Precisely how does a forest system and the individual plants within it react to extreme drought? Understanding the processes involved is crucial to making forests more resilient in the increasingly dry climate that will result from climate change, and also important for refining climate models. A research team led by Prof. Dr. Christiane Werner from the University of Freiburg has conducted the most extensive experiment to date into this subject using stable isotopes to trace flows of water and carbon through a forest.
Ecosystems provide multiple services for humans. However, these services depend on basic ecosystem functions which are shaped by natural conditions like climate and species composition, and human interventions. A large international research team, led by the Max Planck Institute for Biogeochemistry, Jena, identified three key indicators that together summarize the integrative function of terrestrial ecosystems.
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.
Wissenschaftler*innen schlagen eine alternative Strategie zur Kontrolle der Treibhausgase und des globalen Klimasystems vor, die Konzepte aus der Regelungstheorie, insbesondere die Regelung durch geschlossene Kreisläufe, aufgreift. Sie zeigen damit, wie die Zunahme von Kohlendioxid in der Atmosphäre als ein Problem der Staukontrolle behandelt werden kann.
The Global Carbon Project is a large international research project and part of the Future Earth initiative on global sustainability. It strives to develop a comprehensive picture of the global carbon cycle, making available up-to-date estimations of global CO2 emissions and sinks as well as information on the state of the climate system.
On the menu for slugs are not only mosses, lichens and garden vegetables, but also miniscule oribatid mites, which they unavoidably take in with their food. Astonishingly, most of these tiny arachnids survive the voyage through the slug's digestive system without harm and are excreted, alive, elsewhere in the ecosystem. Scientists led by Dr Manfred…
In April 2018 Susan Trumbore received the Benjamin Franklin Medal for her groundbreaking use of radiocarbon measurements in forests and soils to assess the carbon flux between the biosphere and the atmosphere. Her research thus makes an important contribution to understanding climate change.
