In July and August 2022, a man-made environmental disaster occurred in the in the Oder River: a mass die-off of fish, mussels and snails that started in the Polish section of the Oder and then continued downstream until it reached the border Oder. The immediate cause of their death was a toxin-producing (planktonic) brackish water alga, scientifically known as Prymnesium parvum, which was able to grow en masse due to high salinity, high solar radiation, and low water flow. An IGB Fact Sheet summarises the current state of scientific knowledge.

The EU Nature Restoration Law (NRL) awaits its formal adoption within the next weeks. Amongst other goals, the NRL aims to restore 25,000 km of free-flowing rivers by 2030. The NRL represents an important opportunity for the restoration and safeguarding of European rivers, its biodiversity and ecosystem services they provide to people. However, seven central challenges must be anticipated in its implementation, which may compromise its success. 

The flood situation in parts of Germany is slowly easing. It can be expected that after some weeks the rivers will have returned to their beds. But how wide is a natural riverbed? Under what conditions does flooding become dangerous for us – and is it also dangerous for nature? How can we better prepare for such extreme events and which measures are beneficial for both people and nature? The current flood events make it clear that we need to rethink flood protection.

It's not completely still in the water or under the ice during the cold season, even though some organisms in this habitat rest or hibernate. Some fascinating facts about winter survival in lakes, ponds and puddles. Plus: how we can support the animals and plants in our garden pond to survive the cold.

POUNDER, a project by the two junior research group leaders, Lynn Govaert and Stephanie Spahr, has succeeded in the Senate Committee Competition of the Leibniz Association and will be funded in the Cooperative Excellence Programme from January 2024.

Yesterday, at the GEO Ministerial Summit in Cape Town, South Africa, IGB scientist Dr Igor Ogashawara was honored with the GEO Emerging Leader Award. We spoke to him about the award and his field of research.

How can the declining pike stocks in the Bodden be supported? IGB researchers have formulated clear recommendations for politics, authorities and the user groups.

This summer, the water shortage in Europe continues to preoccupy politicians and the public. Small standing water bodies such as natural or artificial ponds, kettle holes or park waters are particularly suffering from the lack of water. In order to raise awareness of this problem and to point out options for action for policymakers, authorities and the civil society, IGB has today published a new IGB Dossier on this important type of water body.
