March 11, 2025Storage hydropower plants contribute to the energy transition, but also affect river ecosystems. Sustainable management should not only account for individual hydropeaking events, but also their cumulative effects.

March 7, 2025New methods are making it possible to gain a more precise understanding of the role of organic molecules in the functioning of ecosystems. Researchers from Eawag and University of Zurich are therefore calling for a new “ecology of molecules”.

January 29, 2025Elena Gimmi received an ETH Medal for her dissertation on the influence of bacterial “bodyguards” on the co-evolution of the black bean aphid and its natural enemy the parasitoid wasp.

November 14, 2024Every year, the Hydrobiology Limnology Foundation for Water Research issues an award for dissertations and master theses on limnology. This year, the prize for the dissertation and master thesis went to researchers at the aquatic research institute Eawag.  

October 31, 2024A new publication by Eawag shows that co-cultures of different microalgae are more resistant to pests than monocultures.

October 22, 2024Forest or farmland: The impact on amphipods in the groundwater is detectable, even if the groundwater extraction site is up to one kilometre away.

October 17, 2024Insects and spiders are superfoods: rich in essential fatty acids and therefore an important food supply for birds, fish, reptiles, amphibians and small mammals.

October 11, 2024Many fish species migrate back and forth between habitats in the course of their lives. However, man-made obstacles make life difficult for these species. Cold-loving fish are also affected by climate change, especially if access to cold-water zones is made more difficult. Renaturalisation can solve this problem. An Eawag project will now help to identify obstacles and remaining cold-water zones so that restoration measures can be planned in a more targeted manner.

October 11, 2024The Swiss fisheries advisory office (FIBER) promotes sustainable fisheries through advice and training. It now has a location in French-speaking Switzerland.
