Climate Change in the Mountains: Alpine Streams Between Fragility and Resilience
Climate change is particularly evident in the high mountains, where glaciers are receding and permafrost soils are thawing, affecting the quantity and quality of water in lakes and streams. This is the topic of a lecture by Eurac Research and the South Tyrol Biodiversity Platform on 9 April at the Museum of Nature. In Italian.
In the Venosta Valley, for example, the degradation of the cryosphere, i.e. all forms of ice (except the ice in the clouds) and snow, is also leading to a deterioration in water quality; heavy metals such as nickel and uranium are accumulating in the rivers and are visible as whitish deposits. Concentrations also exceed the environmental quality limits in the valley, especially in the Adige. The rise in temperature and the disappearance of cold habitats are threatening aquatic ecosystems. Post-glacial landscapes increase hydrological stability by feeding cold springs in which endangered microbes and invertebrates live. Preserving these cold refuges is crucial to tackling the climate crisis.
Stefano Brighenti will speak about this topic at the colloquium in Italian entitled ‘Cambiamenti climatici in montagna: i torrenti alpini tra fragilità e resistenza’. The event, organised by Eurac Research and the South Tyrol Biodiversity Platform, will take place on Wednesday, 9 April at 6 pm at the South Tyrol Museum of Nature; admission is free. Registration on the museum's website at https://app.no-q.info/naturmuseum-sudtirol/calendar/event/532893 is recommended. The lecture can also be viewed online on the museum's YouTube channel at https://www.youtube.com/live/WvHO0Dc1uGE.
Stefano Brighenti conducts research in the field of alpine aquatic ecology and has been analysing the ecological and hydrological effects of climate change at high altitudes for around ten years. His studies include the ecology of Alpine streams in the Venosta Valley, the hydrological significance of glaciers and permafrost and the chemical quality of Alpine waters. Brighenti has also coordinated global research into the climatic resilience of mountain regions and the chemical quality of permafrost-influenced streams.
