Die anthropogenen Emissionen von Lachgas (N2O), ein pro Molekül deutlich stärkeres Treibhausgas als Kohlenstoffdioxid oder Methan, stiegen zwischen 1980 und 2020 um etwa 40% an. Im Jahr 2020 erreichten die anthropogenen Emissionen in die Atmosphäre mehr als 10 Millionen Tonnen pro Jahr, so der neue Bericht „Global Nitrous Oxide Budget 2024“ des Global Carbon Project.
Eine kürzlich in Nature veröffentlichte Studie unter Beteiligung von Sönke Zaehle legt nahe, dass Eucalyptusbäume nicht von steigendem CO2 profitieren. Ein erhöhter CO2-Gehalt führt dazu, dass die Bodenmikroorganismen Phosphor stärker binden. Dieser Mineralstoff im Boden, der für das Wachstum der Bäume unerlässlich ist, steht somit weniger zur Verfügung.
Die Kohlenstoffspeicherung im Boden kann dazu beitragen, den Klimawandel abzumildern. Eine neue Studie zeigt, dass die Bildung mineralgebundener organischer Substanz in erster Linie von der Mineralart abhängt, aber auch durch Landnutzung und Bewirtschaftungsintensität beeinflusst wird.
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.
An international research team succeeded in identifying global factors that explain the diversity of form and function in plants. Led by the University of Zurich, the Max Planck Institute for Biogeochemistry in Jena and the University of Leipzig, the researchers collected and analyzed plant data from around the world.
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.
