Citizen scientists sampled more than 600 rivers, streams, lakes and ponds across Germany. The samples have now been analysed by researchers under the auspices of IGB. In this way, a unique data set emerged that provides evidence of three Germany-wide trends: first, microorganisms in the sediment show signs of chemical stress and antibiotic resistance in their genetic material. Second, excessive artificial lighting at night alters the species composition of underwater microorganisms. And third, all studied water bodies emit greenhouse gases.

Using a robotic fish, the team of David Bierbach and Jens Krause has shown that guppies can anticipate the behavior of their artificial conspecific and predict both the direction and dynamics of its movements.

Wywołana przez człowieka katastrofa ekologiczna, skutkująca masową śmiercią ryb, małży i ślimaków, spowodowała poważne szkody w ekosystemie Odry. Co można teraz zrobić, aby pomóc rzece - i jak można zmniejszyć ryzyko tak poważnych szkód ekologicznych i gospodarczych w przyszłości? 

Lena Heinrich has received the Schwoerbel-Benndorf Young Scientist Award of the German Society for Limnology. The former IGB doctoral student completed her thesis in the research group of Michael Hupfer as part of the international DFG Graduate School "Urban Water Interfaces". 

Researchers from IGB, FUB and HUB developed a pack of cards for ecology and related disciplines. The "Ecologist's Career Compass" helps students and professionals to discover the diversity of career paths in the ecological job market.

The man-made environmental disaster, resulting in masses of dead fish, mussels and snails, has caused severe damage to the Oder ecosystem. What can now be done to help the river – and how can the risk of such major ecological and economic damage be reduced in the future? IGB has published its recommendations in an IGB Policy Brief. 

Intact peatlands are habitats for many rare animal and plant species and important sinks for greenhouse gases. Many peatlands that have been converted to agricultural land should therefore be restored. A current study with IGB participation discusses different strategies for this. The authors make clear that the most commonly used method of flooding former peatlands is problematic.

Many rivers are polluted by nitrogen inputs. An international research project involving the IGB has now investigated for the first time the extent of these inputs, the extent to which they are reduced and the contribution made by floodplain areas to this in the Danube catchment area. The results show how useful the large-scale renaturation of river floodplains is for improving water quality.
