July 20, 2020In addition to ozonation, filters using granulated activated carbon (GAC) are increasingly being deployed to eliminate trace substances from municipal wastewater. Working in conjunction with authorities and representatives from the field, Eawag has developed a document that will assist stakeholders with planning in relation to such measures.
July 17, 2020Biodiversity and thus the state of river ecosystems can now be predicted. To achieve this, researchers from the University of Zurich and Eawag (Aquatic Science and Technology) are combining environmental DNA with hydrological methods. Using the river Thur as an example, the approach allows identifying target areas for conservation and initiating protective measures.
July 14, 2020Four young researchers from the department SWW received an “Early Postdoc.Mobility fellowship” from the SNSF to broaden their scientific profile abroad: Mariane Schneider, Lena Mutzner, Omar Wani and Matthews Moy de Vitry. The four have already worked together as a team during their doctorate and have published, among other things, a review for the future of water management.
July 9, 2020The Verband zum Schutz des Greifensees (VGS) (Association for the Preservation of Lake Greifensee) elected its new Council of Delegates on 25 June 2020. In addition to representatives of all municipalities surrounding the lake, the committee also includes cantonal agencies, farmers, fishermen, sailors and – for the first time – a research representative, with the election of Eawag’s Piet Spaak as an aquatic ecologist.
July 7, 2020Natural environments vary in space and time and are now drastically changing due to human activities. Environmental changes, like increasing acidity in a pond, can strongly affect the long-term prospects of species. Katja Räsänen from Eawag’s department Aquatic Ecology aims to understand how natural populations of the moor frog adapt to environmental change.
June 23, 2020A new social-ecological approach allows complex relationships in ecosystem governance to be modelled as abstract but easily grasped networks.
June 17, 2020Since spring 2018, the newly developed underwater camera Aquascope has been recording a wide variety of plankton species in Lake Greifen. These sensitive organisms can thus, for the first time, be observed undisturbed in their natural habitat – an important step towards automated monitoring of water quality and aquatic biodiversity.
June 10, 2020Thanks to a new instrument, water pollutants can be measured automatically over a period of weeks – directly in the field, rather than in the laboratory. The mobile mass spectrometer is housed in a trailer and can be remotely controlled by smartphone.
June 3, 2020If one observes the competition between parasites and symbionts, much can be learned about the theory of evolution. Two Eawag researchers have thus shown in a new study that high parasite diversity promotes symbiont diversity.
May 28, 2020Around 500 different cichlid species are found in Lake Victoria. According to a study by scientists at Eawag and Bern University, whether closely related species can persist within the same area depends on the effect sizes of individual genes underlying key mate-choice traits.
