Together with a large international team the study’s first author, Prof. Dr. Peter Haase of the Senckenberg Research Institute and Natural History Museum in Frankfurt and Dr. Ellen A. R. Welti of the Smithsonian’s Conservation Ecology Center in the US analysed a comprehensive dataset of 1,816 time series of freshwater invertebrate communities between 1968 and 2020 from 22 European countries, comprising 714,698 individuals of 2,648 taxa from 26,668 samples. The analysis reveals a plateauing trend, the biodiversity indexes showed positive trends until the 2010s, after which the recovery rates have significantly slowed down.
