Eawag - Swiss Federal Institute of Aquatic Science and Technology - Eawag

Researchers Juliane Hollender, Ole Seehausen, Bernhard Truffer and Urs von Gunten from the aquatic research institute Eawag are among the "highly cited researchers 2020".

In the journal ZooKeys, a group of scientists from Eawag and Bern University have described seven whitefish species endemic to the Bernese Oberland lakes – including four not previously described scientifically, two of which have only been identified as distinct species in the last few years. In Switzerland, the whitefish diversity of Lakes Thun and Brienz is possibly matched only by that found in Lake Lucerne; and in deep lakes of this kind further surprises cannot be ruled out.

In agricultural areas, large volumes of water from fields, roads and paths drain directly into streams via manholes and other forms of artificial drainage. These shortcuts also transport pesticides into surface waters – and, according to a new study, in significantly larger quantities than was previously assumed.
