Naturalne przyczyny tej zaistniałej katastrofy są mało prawdopodobne. Ostatnie badania wzmocniły podejrzenie, że w Odrze masowo rozwinęły się toksyczne glony słonawowodne.

Neueste Untersuchungen erhärten den Verdacht, dass die Massenentwicklung einer giftigen Brackwasser-Alge in der Oder stattgefunden hat. Von einem natürlichen Phänomen gehen die Forschenden nach wie vor nicht aus, denn die Algenart Prymnesium parvum kommt auf den betroffenen Oder-Abschnitten unter natürlichen Bedingungen nicht massenhaft vor. 

The environmental disaster on the Oder river also leaves researchers from the IGB in a great sense of shock. They the are currently tracking down a strong toxin that can be produced by the algae species Prymnesium parvum. Even if this suspicion is confirmed, it is not a natural phenomenon, but definitely a man-made problem.

Low-growing species such as stoneworts were last sighted in the Müggelsee over a century ago. Now, after 20 years of intensive mapping and diving surveys, not just one but three of these desirable species of underwater vegetation have been found.

German scientists have summarised in a policy brief what smart flood protection should look like and what benefits nature-based solutions in particular provide. 

Dry banks instead of expanses of water, trickles instead of torrents. With climate change, freshwater bodies are losing water. Researchers of IGB are investigating what this means for people and ecosystems. Over the next few weeks, they will answer 10 questions on the topic.

Our planet is experiencing a dramatic decline in biodiversity. Freshwater plants and animals are particularly at risk. IGB scientists reveal where and why freshwater habitats are declining.
