A new social-ecological approach allows complex relationships in ecosystem governance to be modelled as abstract but easily grasped networks.

Since 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.

Thanks 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.

If 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.

Around 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.

Many experts describe the health effects of drinking water contaminated with toxic concentrations of arsenic as the greatest mass poisoning in human history. A risk model developed by Eawag researcher Joel Podgorski now shows that up to 220 million people worldwide could be affected.

To mark this year’s International Day for Biological Diversity on 22 May, professor Catherine Graham and professor Florian Altermatt explain in an interview why it is important in biodiversity research to look beyond systemic boundaries. The two scientists lead the joint research initiative “Blue-Green Biodiversity” between WSL and Eawag.

To protect ecosystems, it is important to understand how environmental disturbances, such as forest fires or hurricanes, affect nature. A study by Eawag and the University of Zurich now shows how their frequency and intensity affect small and large organisms. Accordingly, large species are more affected by disturbances than small species, and this influences the size distribution within ecological communities.

In order to increase the permeability of the rock for applications such as the use of geothermal energy, rock is artificially broken. Until now, there was a lack of methods to track this process in the field in real time. Thanks to a new technique, this gap can now be closed, as a study by Eawag and ETH Zurich shows.
