Manuel Fischer, tenure track researcher and group leader within the Department Environmental Social Sciences, has successfully passed his habilitation exam at the University of Bern. In his habilitation, he pointed out the factors that influence collaboration among political actors.  Read more

Lake Constance: sustainable thermal use is possible in the case of deep Swiss lakes (Photo: plainpicture/Westend61/Holger Spiering)
March 16, 2017

Switzerland’s surface waters contain vast amounts of thermal energy which could be used for heating or cooling. Based on numerous studies, Eawag scientists have now estimated the ecological impacts of thermal use.  Read more

Assessments of the ecotoxicity of pharmaceuticals focus on parent compounds because data on transformation products is generally unavailable. (Photo: Caro/Sorge)
March 14, 2017

Over 8000 pharmaceuticals, with more than 3000 active substances, are currently authorized in Switzerland. Transformation products – arising from biological and chemical degradation processes – can sometimes be more toxic to aquatic organisms than the parent compounds; they may also be problematic as a result of their higher mobility.  Read more

The water footprint indicates how much water is used to produce consumer goods. A study by Eawag scientists shows that there is a need for standardization in assessments of the grey water component. Comparability is impaired, for example, by the use of different water quality standards.  Read more

As a result of climate change, concentrations of the trace element selenium in soils are likely to decrease. Because the selenium content of crops may also be reduced, the risk of selenium deficiency could be increased in many regions of the world. This was shown by a recent study which used data-mining to model the global distribution of selenium. Read more

Biodiversity can promote ecosystem efficiency
February 16, 2017

Humans influence evolution. In the case of whitefish in Swiss lakes, one consequence of this is replacement of a diversity of specialised species by fewer generalists. A recent analysis now suggests that communities of diverse specialists utilise trophic resources more efficiently. Read more

Periodic oscillations of bottom-water oxygen concentrations can alter benthic communities and carbon storage for decades, reveals a new study published in Science Advances. This is particularly relevant as low oxygen conditions are on the rise in the world’s oceans. Read more

Kreuzung zweier Arten liess Artbildung explodieren

No less than 500 new species of cichlids, brightly coloured perch-like fish, evolved in Lake Victoria (East Africa) over the past 15,000 years – a record in the animal and plant world. This evolutionary puzzle has now been solved by scientists from Eawag and Bern University. Read more
