December 9, 2021In the "Projet Lac" research project, 35 lakes in the Alpine region were systematically examined for their fish populations for the first time: In Switzerland alone, 106 fish species were detected. With almost 20 percent of all known fish species in Europe, Switzerland is one of the hotspots for fish species diversity. The results are now the basis for measures for sustainable fishing and the protection of this still preserved diversity.

December 2, 2021Researchers from 90 scientific institutions worldwide have stated that freshwater biodiversity research and conservation lag far behind the efforts carried out in terrestrial and marine environments. In a new publication in Ecology Letters, they propose a research agenda with 15 priorities aimed at improving research on biodiversity in lakes, rivers, ponds and wetlands. This is urgently needed, as biodiversity loss is taking place much faster in inland waters than on land or in the oceans.

November 25, 2021Eawag intends to further develop artificial intelligence methods to enable their increasing use in water research. One current application is the monitoring of plankton communities in lakes. With the help of machine learning methods, it has been possible to implement an automatic classification of the microorganisms.

November 19, 2021Rising temperatures, invasive species and other factors have changed the composition of species in Lake Constance over the last century. Researchers are trying to understand how this could have happened and what it means for the lake.

November 18, 2021A flood causes stress for organisms living in a watercourse. Their survival depends on factors such as whether there are refuge habitats to which they can retreat. Researchers at VAW and Eawag studied how river widening as part of restoration measures improves potential refugia availability. They showed that refugia provision and thereby the protection of biodiversity depends crucially on the supply of bedload.
