First nationwide citizen science project GartenDiv launched

May 20, 2025

The Germany-wide citizen science project GartenDiv will research plant diversity in Germany's gardens for the first time. A one-year pilot project will provide an overview of which plants thrive in gardens across the country.

How gaps in the canopy of a floodplain forest influence microclimate and soil biological activity

September 24, 2024

Biodiversity Christian Wirth Ecosystem Function Forest Dieback

A study by Leipzig University, the German Centre for Integrative Biodiversity Research Halle-Jena-Leipzig (iDiv) and the MPI for Biogeochemistry shows that gaps in the canopy of a mixed floodplain forest have a direct influence on the temperature and moisture in the forest soil, but only a minor effect on soil activity.

Using artificial intelligence for better understanding the Earth system

Artificial Intelligence Carbon Cycle Climate Change Climate Extremes Nuno Carvalhais

EU funds the international research project AI4PEX to further improve Earth system models and thus scientific predictions of climate change. Participating scientists from 9 countries met at the end of May 2024 to launch the project at the MPI for Biogeochemistry in Jena, which is leading the project.

Biodiversity Ecology Jana Wäldchen Research project Flora Incognita

From the Greek philosopher Aristotle to Charles Darwin to the present day, scientists have dealt with this fundamental question of biology. Contrary to public perception, however, it is still largely unresolved. Scientists have now presented a new approach for the identification and delimitation of species using artificial intelligence (AI).

In a grassy field, a hand holds a smartphone capturing an image of bright yellow flowers. The phone screen shows the flowers in focus, with green grass in the background.

How a plant app helps to identify the consequences of climate change

Biodiversity Climate Change Ecology Jana Wäldchen Plant Traits Research project Flora Incognita

A research team led by the German Centre for Integrative Biodiversity Research (iDiv) and Leipzig University has developed an algorithm that analyses observational data from the Flora Incognita app. The novel can be used to derive ecological patterns that could provide valuable information about the effects of climate change on plants.

Precisely predicting allergenic pollen with AI

April 19, 2024

Artificial Intelligence Jana Wäldchen Phenology Research project Flora Incognita

The new research project "PollenNet" aims to use artificial intelligence to accurately predict the spread of pollen. In order to improve allergy prevention, experts are bringing together the latest interdisciplinary findings from a wide range of fields.

Land under water – what causes extreme flooding

March 27, 2024

Artificial Intelligence Climate Extremes Shijie Jiang

If rivers overflow their banks, the consequences can be devastating. Using methods of explainable machine learning, researchers at the Helmholtz Centre for Environmental Research (UFZ) have shown that floods are more extreme when several factors are involved in their development.

Plant identification via app enables phenological monitoring

March 14, 2024

Biodiversity Jana Wäldchen Plant Traits Research project Flora Incognita

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.

Professor Christian Wirth in the Botanical Garden of University Leipzig

Honored: Christian Wirth appointed External Scientific Member of the Max Planck Institute for Biogeochemistry

Biodiversity Christian Wirth Personalia Plant Traits TRY database

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.

Deciphering nature's climate shield: Plant diversity stabilises soil temperature

December 12, 2023

Biodiversity Climate Change Ecosystem Function Gerd Gleixner Jena Experiment

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.
