Glacial relicts: who are they?

Let's introduce ourselves: we are a group of animal species often referred to as "glacial relicts." Does that make you laugh? After the great glaciation, we were trapped in some parts of the Alps because we can only live here. The park carries out important research for the conservation of biodiversity and also monitors endangered species like us, whose real threats are anthropogenic disturbance, habitat loss, and climate change. For example, I am the White Partridge. I keep pretty much to myself, but you might see me fly by in the morning or evening. I'm probably stubborn, but I need my ideal temperature to survive, so just a few degrees more, and you can give me a final farewell!

Imagine, then, the splendor of the summer colors that give way to autumn. Some species migrate, and others descend to a lower altitude. But not everyone leaves; many face the cold season with a soft down. But, the more we climb where the climate becomes inhospitable, the rarer the species that winter there. For some of these, evolution has chosen particular survival strategies: Alpine Marmots go into hibernation, while White Artists change the colour of their fur or feathers until they camouflage with the white snow cover. I am referring to myself, of course, but also to the Mountain Hare and the Stoat, help!, sometimes our greedy predator! They are completely different species but have followed convergent evolutionary strategies, Darwin would say! But will we be able to adapt again?
