Climate change not only modifies the distribution of individual species but can also alter the relationships that have linked predators and prey in alpine ecosystems for thousands of years. This is the main conclusion of the scientific article published in the journal Mammal Research
The Eurasian eagle-owl is the largest nocturnal bird of prey in Europe and one of the most majestic birds in our mountains. Its wingspan can reach and exceed 180 centimeters, while its weight typically ranges from 2 to 3.5 kilograms, with females being sturdier than males. It is unmistakable for its large bright orange eyes and the tufts of feathers on its head, which resemble ears and are raised particularly when it is alert.
The ermine (Mustela erminea) is an agile and sprightly mustelid, widespread across much of Eurasia and North America. It is also found in the Alps, where it prefers open mountainous environments rich in natural burrows, pastures, high-altitude meadows, and areas with scattered bushes. It is a small-sized carnivore: the body measures between 17 and 33 centimeters, the tail between 5 and 12 centimeters, with a weight that varies from 100 to 450 grams. Males are significantly larger than females.
