Ecosystem

The diversity of whitefish species in Swiss lakes is unique and plays a central role in lake ecosystems. A comprehensive Eawag report now summarises the results of 150 years of research on these fish. They make it clear that the mechanisms and environmental conditions that have contributed to their development must be taken into account in order to preserve this species diversity. Last but not least, protecting whitefish diversity helps to preserve the natural yield potential of lakes as a source of food for humans.

To enhance biodiversity in water and on land, we need high-quality, interconnected natural areas. Here the cooperation of different stakeholders is essential.

To contain the spread of the invasive quagga mussel, Eawag researchers recommend swift action based on comprehensive prevention, early detection and containment.

Not only are the numbers of species declining, but the composition of species communities is also changing. This is shown by a new study published in the journal “Nature”.

Two EPFL-led articles published in 'Nature' and 'Nature Microbiology' shed light on the uniqueness, complexity and climate-related vulnerability of the world’s glacier-fed-stream microbiome.
