A research team has investigated the interplay between hydrology and microbial communities in small water bodies in Berlin. They discovered many microorganisms that indicate a higher anthropogenic influence. The reason: small watercourses such as the Panke or the Erpe mainly carry treated effluent – accounting for up to 100 per cent of the total discharge volume in summer.

Researchers from the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) analysed various bodies of water in Berlin for traces of nicotine. They detected nicotine in all of the samples, with concentrations ranging from 7 to around 1,500 nanograms per litre. Nicotine from discarded cigarettes primarily enters water bodies via heavy rainfall and the sewage system. 

IGB has provided feedback on the planned EU ports strategy and emphasised that environmental aspects play a decisive role for resilient ports.

Head out to the lake for a swim, but have you ever wondered what might be swimming, growing or crawling in the water? A catfish recently attacked several people in the Brombachsee, a lake in Franconia. But just how dangerous are these predatory fish? What other creatures might you encounter in the lake? We take a look at the diverse underwater world of animals and plants, from the harmless to the astonishing.

In an ICPO consultation, the IGB recommends that the salinity of the Oder should be made an important management issue. 

A new joint Policy Report by the German National Academy of Sciences Leopoldina and the Brazilian Academy of Sciences (Academia Brasileira de Ciências, ABC), to which IGB researchers also significantly contributed, shows what sustainable and circulation-orientated aquaculture could look like in Germany and Brazil.

IGB gave feedback in the Call for Evidence on the new EU Bioeconomy Strategy and highlighted the central role of water and freshwater ecosystems.

Today on Earth Day, the 19 National Champions of the Frontiers Planet Prize, a globally significant research prize for sustainability, were announced. Robert Arlinghaus, Professor of Fisheries at the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) and the Humboldt Universität zu Berlin, and his team are recognized for their groundbreaking publication in Science on the effectiveness of habitat improvement on fish populations in lakes.
