Protecting the Biodiversity of High-Mountain Lakes
High-mountain lakes are often perceived as pristine natural environments, far removed from human pressure and seemingly untouched. However, this idyllic image does not always reflect reality. Even in these remote ecosystems, human activity has left its mark on biodiversity. On the occasion of the International Day for Biological Diversity, the LIFE RESQUE ALPYR project highlights…

Pioneering pilot test for the ecological restoration of high mountain lakes using a biodegradable piscicide
The pilot test, which will start this week, aims to eliminate introduced species and restore the ecological balance of these high-mountain ecosystems. The trial will involve the use of rotenone, a biodegradable ichthyocide. The results of the action will provide essential data to evaluate the effectiveness and safety of this product, contributing to the development…

Some truly special tadpoles!
Many mountain lakes and ponds are teeming with Rana temporaria tadpoles, but just a few days ago, we encountered some truly special ones! They are seven tadpoles observed at Lake Leità, within the Gran Paradiso National Park. Their presence indicates that Rana temporaria has successfully reproduced in the lake, and since one of the tadpoles…

New study warns of the decline of cold-adapted zooplankton in Alpine high-mountain lakes
A new scientific study, published in the journal Biological Conservation and led by the LIFE RESQUE ALPY project, has documented a rapid disappearance of cold-adapted zooplankton in high-altitude lakes of the Western Alps. These microscopic organisms, which serve as key bioindicators of ecological health, are declining as a result of global warming and the introduction…
