September 8, 2016Biologists at Eawag have described a new amphipod species which is endemic to the Alps. While alpine lakes provide relatively undisturbed habitats for Gammarus alpinus, this species is being displaced by an invasive amphipod in Lake Constance.

September 6, 2016Lakes are major ecosystems. Their secrets have been investigated in Switzerland for more than 100 years. Nonetheless, scientists and their partners at the federal and cantonal specialist departments can still be surprised. For example, a fish in Lake Constance that had been declared extinct, or the results of Roman forest clearing around Lake Murten or concentrated antibiotic-resistant genes in the vicinity of wastewater discharges in Lake Geneva.

August 30, 2016“We should soon be able to monitor biodiversity just as we can now assess water chemistry,” says Florian Altermatt of the Aquatic Ecology department. Genetic material is known to be continuously released into the environment (eDNA) – e.g. in faeces or skin cells – and the biologists now demonstrated the practicability of this approach. In one litre water from the Glatt river (Canton Zurich), they identified numerous species ranging from the mayfly to the beaver. The method can be automated.

August 23, 2016Despite extensive conservation efforts, the global loss of biodiversity is continuing. According to an article by biologists at Eawag and Zurich University, published in the Journal of Applied Ecology, this is partly due to the inadequacy of existing conservation measures.

August 17, 2016Political actors tend to perceive their opponents as more influential than they really are, and to overestimate the differences between opposing groups. As a result, policy‑making and the search for feasible compromises become more difficult. This phenomenon, as Eawag political scientists have now shown, is apparent even in a consensus-based democracy like Switzerland.

August 15, 2016The VUNA recycling process, which recovers nutrients from urine, recently had its own display as part of an exhibition at the “Umwelt Arena” (Environment Arena) in Spreitenbach. Eawag’s exhibit was designed to raise awareness amongst visitors to the exhibition of the fact that wastewater also contains reusable substances, which can be used, for instance, for making fertilizers.

August 11, 2016Ole Seehausen, Head of the Department of Fish Ecology and Evolution at Eawag in Kastanienbaum and Professor of Aquatic Ecology at the University of Bern has been awarded the “Kilham Memorial Award” by the International Society of Limnology (SIL). Last week, at the 33rd SIL Congress, he gave the Kilham Memorial Lecture in Turin.

July 12, 2016The new laboratory and experiments building the “Aquatikum” on the grounds of Eawag, the Swiss Federal Institute of Aquatic Science and Technology, in Dübendorf is the first laboratory building in all of Switzerland to receive the Minergie P-Eco Certificate. This commendation honours not only an especially sustainable use of energy, but also the care exercised in choosing building materials and procedures that are both ecologically sound and conforming to health and safety standards.

June 29, 2016In recent decades, Swiss water protection efforts have focused on reducing nutrient inputs; today, one of the main concerns is controlling micropollutants.

June 23, 2016When water enters a new plumbing system for the first time, microorganisms will immediately start to colonize the pipes.
