Copepods (minute crustaceans with paddle-like feet) can differentiate between disturbances in water generated by nearby organisms and turbulence caused by wind or waves – an ability which helps them to find mates. It had previously been assumed that turbulent conditions would impede the quest for mates.

A new simulation study shows that climate change risks significantly altering water temperature, ice cover and mixing of many Swiss lakes. Mid altitude lakes are especially under pressure, running the risk of completely losing ice cover and no longer fully mixing twice per year. Such a change would have fundamental consequences for the functioning of lake ecosystems.

A community of sulfur bacteria grows in the northern basin of Lake Tanganyika and plays a key role in the lake's nitrogen cycle. With climate change, the deep blooms could expand southward, a new study shows. This could have drastic consequences for regional fisheries.

Beavers are master builders that reshape aquatic landscapes with their dams and lodges. The environments they inhabit experience an increase in the biodiversity of aquatic organisms, for example. Now, for the first time, an Eawag study from the wine-growing region known as “Zürcher Weinland” has shown that this is also true for streams in areas given over largely to agriculture. The rodents could therefore be interesting partners when it comes to enhancing bodies of water.

Surfaces which are frequently touched by many different people may be contaminated with the coronavirus, but the risk of infection via this route is low. However, regular collection of samples from door handles, buttons or keypads could be useful for monitoring the course of the pandemic.

Each year, around 130 kilograms of mercury flow into Swiss wastewater treatment plants, which filter out the lion’s share from the waste water. This is shown by a survey of almost thirty wastewater treatment plants conducted by the Swiss Federal Institute of Aquatic Science and Technology (Eawag) and the Federal Office for the Environment (FOEN).

Europe still has barely any downstream passage facilities that guide fish past the turbines of run-of-river power stations unharmed. Now, an interdisciplinary team of engineers from ETH Zurich and fish biologists from Eawag have developed a rack that uses pressure and flow differences to guide fish out of the main flow and into the safe fish passage. Laboratory tests have shown that the system, which works by influencing fish behaviour, is particularly effective for cyprinid fish and salmon parr.

The mobile and automated MS2field mass spectrometer allows measurements to be taken of harmful substances in surface waters with high temporal resolution. The initial measurements using the device are revealing the extent to which peak concentrations of pesticides, for example, have been underestimated by traditional methods.

The analysis of DNA fragments and their assignment to individual species – an increasingly well‑established approach – is transforming biodiversity assessment. Samples collected from waterbodies permit rapid biomonitoring of aquatic ecosystems. However, environmental DNA (eDNA) analysis is not without pitfalls. For this reason, guidelines for practitioners have now been developed by a group of experts – including Eawag scientists – coordinated by the Federal Office for the Environment. These guidelines, covering the whole process from sampling to data interpretation, should help to ensure that eDNA applications produce reliable results.

In the journal ZooKeys, a group of scientists from Eawag and Bern University have described seven whitefish species endemic to the Bernese Oberland lakes – including four not previously described scientifically, two of which have only been identified as distinct species in the last few years. In Switzerland, the whitefish diversity of Lakes Thun and Brienz is possibly matched only by that found in Lake Lucerne; and in deep lakes of this kind further surprises cannot be ruled out.

In agricultural areas, large volumes of water from fields, roads and paths drain directly into streams via manholes and other forms of artificial drainage. These shortcuts also transport pesticides into surface waters – and, according to a new study, in significantly larger quantities than was previously assumed.
