Plant observations collected with plant identification apps such as Flora Incognita allow statements about the developmental stages of plants - both on a small scale and across Europe.
We have gained a new external member: Prof. Dr. Christian Wirth has been appointed by the Senate of the Max Planck Society as External Scientific Member. As a former group leader and later fellow at the institute, Prof. Wirth initiated and supported the development of the TRY database, the world's largest collection on plant traits.
A new study shows a natural solution to mitigate the effects of climate change such as extreme weather events. Researchers found that a diverse plant community acts as a buffer against fluctuations in soil temperature. This buffer, in turn, can have a decisive influence on important ecosystem processes.
Removing a tonne of CO2 from the air and thus undoing a tonne of emissions? Doesn't quite work, says a study. And provides four objections in view of Earth systems.
The new report by the Global Carbon Project shows: Fossil CO2 emissions will reach a record high in 2023. If emissions remain this high, the carbon budget that remains before reaching the 1.5°C limit will probably be used up in seven years. Although emissions from land use are decreasing slightly, they are still too high to be compensated by renewable forests and reforestation.
Storing carbon in the soil can help to mitigate climate change. Soil organic matter bound to minerals in particular can store carbon in the long term. A new study shows that the formation of mineral-associated organic matter depends primarily on the type of mineral, but is also influenced by land use and cultivation intensity.
The Deutsche Forschungsgemeinschaft (DFG) is to fund a Research Unit in the Jena Experiment for a further four years with around five million euros. The new focus is on the stabilising effect of biodiversity against extreme climate events such as heat, frost or heavy rainfall.
