Researchers have compiled and analyzed the key environmental factors that led to the mass development of the brackish water alga Prymnesium parvum in the Oder in the summer of 2022. The data synthesis shows how multiple stressors combined to allow an alga that normally thrives in stagnant salt water to proliferate en masse in a completely atypical habitat. In addition, a study on the quantitative impact on fish stocks in the Oder was published: compared to before the disaster, fish and mussel stocks have been decimated by more than half.

Desiccating salt lakes are an underappreciated source of greenhouse gases that could become even more relevant as a result of climate change. Newly announced research by the Royal Ontario Museum (ROM) in the USA in cooperation with the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) examining greenhouse gas emissions from the drying lake bed of Great Salt Lake, Utah, calculates that 4.1 million tons of carbon dioxide and other greenhouse gases were released in 2020.

IGB researcher Mina Bizic has been appointed Professor and Chair of Environmental Microbiomics at the Technical University of Berlin (TU Berlin). We spoke to the scientist, whose work is dedicated to the smallest living organisms in water.

Researchers from IGB sequenced the complete genome of the microalgae of the Oder disaster.They also identified the gene sequences that are responsible for toxin formation. This is an important step on the way to an early warning system. The study was published in the journal Current Biology.

IGB researcher Prof Michael Hupfer has been elected as a new member of the Leibniz-Sozietät der Wissenschaften zu Berlin e.V. The learned society is thus honouring his achievements in the field of aquatic ecology and his commitment to water protection. 

Buying fish, sausage or meat saves you from breaking a social taboo in some industrialized nations, especially when hunting and fishing are conducted for recreation. In a perspective article in Nature Sustainability, a research team from the natural and social sciences and environmental philosophy adds a new perspective to the topic of "recreational use of wild animals". The hypothesis is that an emotionally intense interaction between hunters or anglers and wild animals can create a particularly strong sense of responsibility,

When the weather is nice, it is time to go swimming in a lake, canoeing on a river or having a picnic by the water. The Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) shares do's and don'ts for environmentally friendly water fun – including some that are not so obvious.

Researchers under the lead of Hans-Peter Grossart have now identified fungi that can efficiently degrade plastic polymers made of polyurethane, polyethylene and tyre rubber. Contrary to previous assumptions, no pre-treatment of the plastics was necessary. The study has been published in Science of the Total Environment.
