Glacial melt threatens habitats of alpine river organisms
Research
Eawag
When glaciers retreat, the habitats for cold-water organisms also change. Researchers have now modelled where refuges that are vital for biodiversity in glacial rivers will remain in the future.
DNA traces in groundwater
Research
Eawag
An Eawag study shows that a large variety of living organisms leave their DNA traces in groundwater – which also depends on the land use in the catchment area. In future, these biological parameters could be used to assess groundwater quality.
What causes insects to disappear
Research
WSL
There are fewer and fewer insect species, individuals and biomass worldwide. Moreover, their composition is becoming more uniform. This is highlighted in a special issue of the journal Biology Letters. It outlines the causes and consequences of the global crash of insect populations and possible measures to counter it.
Fungi's beneficial effects on coral are not yet fully understood
Research
EPFL
Until now, most studies of fungi have focused on their role in marine disease. But according to research done at EPFL, these fungi may also help protect coral reefs against climate change. 
Research for crisis management
Politics
ETH Board
Species decline, increasing extreme weather events as a fallout of global warming and, on top of it all, the war in Ukraine, which has also brought about uncertainties regarding energy supply and digital transformation: We are living in a challenging time in which several crises are being felt at once. Meanwhile, scientists from the ETH Domain are faced with a lot to tackle. They are investigating a diverse range of issues. Drawing on the expertise they have acquired, they are developing proposals for solutions to assist citizens, the authorities and politicians with advice and support.
Fish diversity documented in Switzerland’s rivers
Research
Eawag
In a survey of Swiss rivers and streams, more than 50 different fish species were recorded. For the first time, more than one species was also found in the case of smaller types of fish such as the bullhead.
