March 28, 2023In a survey of Swiss rivers and streams, more than 50 different fish species were recorded. For the first time, more than one species was also found in the case of smaller types of fish such as the bullhead.

March 27, 2023A forest is crucial for life in streams, particularly in the catchment area and in the headwaters. This effect is especially significant in the case of sensitive species.

March 23, 2023Thanks to a unique data set from lakes, Eawag has succeeded in determining how plankton networks respond to climate change and phosphate levels.

March 2, 2023The updated Red List of fish documents a further endangerment. Prof. Ole Seehausen explains why.

February 27, 2023Where is there still untapped potential in the use of water bodies for energy generation and what are the associated risks for water systems?

February 2, 2023Biologists at Eawag have identified ten species of whitefish in the lakes of the Reuss river system. Of these, seven have been described as distinct species for the first time – although in two cases this required inspection of specimens from historical collections, since eutrophication of lakes in the 20th century also led to the extinction of fish species in Central Switzerland.

January 27, 2023Switzerland's groundwater is home to a multitude of hitherto unknown organisms. An Eawag research project is shining a light into the darkness and revealing this habitat’s exceptional biodiversity.

January 26, 2023Where do the toxic metals come from at the bottom of Lake Zurich near Horn Richterswil? With analyses of sediment cores, researchers at Eawag were able to solve the mystery.

January 23, 2023Too much nitrogen enters many water bodies. The anammox process co-developed by Eawag can contribute to reducing outputs from wastewater treatment plants.

January 17, 2023A new integrative approach to biodiversity research shows how ecosystems on land and in freshwaters can be better protected by considering fundamental ecological processes.
