Max Planck Institute for Biogeochemistry

The Max Planck Institute for Biogeochemistry in Jena conducts research into global material cycles and the associated chemical and physical processes. Carbon, oxygen, hydrogen and nitrogen are four elements that are crucial to life whose compounds are transported by plants, animals and microorganisms and distributed via the air and water. The scientists in Jena seek to gain a better understanding of the complex interaction between the organisms in the soil and the greenhouse gases in the atmosphere, as well as the influence of humans on these natural processes. How do ecosystems react to various climate conditions, land-use practice and species diversity? To this effect, scientists at the Institute compare historical data with current observations from field experiments and measurement campaigns in order to draw conclusions on the future adaptability of organisms. They also work closely with the Max Planck Institutes for Meteorology in Hamburg and Chemistry in Mainz.

Over a trillion tons of carbon are sequestered in permanently frozen soils (permafrost), especially in the Arctic Circle. But this frozen ground is steadily thawing as a result of climate change. Whether or not this will lead to the release of large quantities of greenhouse gases is one of the vital unresolved questions in climate research. Mathias Göckede, who heads a research group at the Max Planck Institute for Biogeochemistry in Jena, is among those looking into this question and he has already come up with some surprising answers.

Climate change is devastating forests in Germany and other European regions. Our traditional understanding of which tree species can withstand heat and drought no longer holds true, which is why ecophysiologist Henrik Hartmann is calling for the creation of an interdisciplinary Institute for Forest Conversion. This new institute would provide scientific insights into how forests can be constituted to be able to withstand ongoing global warming.

Droughts, heatwaves, and floods – climate change is likely to make extreme weather and climate events such as these more frequent and more intense. Markus Reichstein, Director at the Max Planck Institute for Biogeochemistry in Jena, and his team are working on predicting the impacts of such events. Reichstein uses large volumes of data in conjunction with artificial intelligence to carry out this research, which he hopes will make societies more resilient to extreme climate events.

Forests can remove large amounts of CO2 from the atmosphere. So far, there is consensus about this throughout the scientific community. However, there is some dispute about how forests can best protect the climate - whether they should be managed sustainably or left undisturbed. Right in the middle of this dispute is Ernst-Detlef Schulze, Director Emeritus at the Max Planck Institute for Biogeochemistry in Jena.

Threats to ecosystems from recurring extreme events

2021 Ana Bastos und Markus Reichstein

Climate Research Earth Sciences Ecology

The frequency of extreme weather and climate events increases with each additional degree of global warming.  Such events impact key ecosystem function leaving legacies over several years. As the intervals between stress conditions shorten, the recovery time between two events is limited, threatening ecosystem stability. Remote-sensing is a valuable tool for monitoring vegetation condition and impact/recovery pathways associated with extreme events. Such information can provide important insights into management strategies to mitigate some of the impacts of climate change.

The endangered skin we live on

2020 apl. Prof. Dr. Gerd Gleixner

Climate Research Earth Sciences Ecology Microbiology

The life and survival of humans on Earth depends on the functioning of the outermost layer of our planet, the "Critical Zone." In the Anthropocene, human actions have interfered with the exchange of matter between organisms and ecosystems, threatening the functioning of the Critical Zone. We examine how biodiversity loss reduces continental carbon storage, accelerating climate change. The world of soil microorganisms is the focus of our interest, as this is where the molecular drive of global matter cycles is hidden.

Klimaextreme: Von der Detektion bis zur Vorhersage

2019 Mahecha, Miguel;  Reichstein, Markus

Climate Research Earth Sciences Ecology Microbiology

Climate extremes, in particular heat waves, droughts, and their combination are inevitably increasing as a result of climate change. But little is known about how these events affect the terrestrial biosphere, which ecosystem functions are severely affected, and what feedbacks this may trigger in the climate system. At the Max Planck Institute for Biogeochemistry we are developing new methods for the detection of extreme events in heterogeneous data streams. Our results show, among other things, how differently various ecosystems can react to extreme events.

Water, ice and snow: Driving forces of climate change in the Arctic

2018 Dr. Mathias Göckede

Climate Research Earth Sciences Ecology Microbiology

How stable carbon will remain in the Arctic permafrost in the future, instead of escaping into the atmosphere as a greenhouse gas, is of utmost importance for the global climate. Water, ice and snow play an important role here. Our field research in Siberia uses new data and models to explain how the redistribution of water and increased snow cover, two known consequences of current climate change, can further destabilize the carbon pools in the Arctic. Our results help to assess the role of the Arctic in global climate change more reliably.

The competition of plants and soil microorganisms for important nutrients such as nitrogen and phosphorus is a key determinant of the amount of carbon that can be stored in land ecosystems. Combining new laboratory experiments and improved numerical ecosystem models generates new insights into the intricate effects of this nutrient limitation for the future development of land carbon storage. This research contributes to a better understanding of the effects of anthropogenic carbon dioxide emission of climate.
