Boloria pale s (Shepherd’s fritillary), a butterfly species found at high-elevation and typical of grassy alpine areas, occurs across several mountainous regions in Europe. It can now be found at higher elevations in Switzerland. Here, the species is pictured on a typical mountainous plant that is also shifting upslope as climate warms ( Arnica montana or Mountain arnica)

The European Alps is certainly one of the most scrutinized mountain range in the world, as it forms a true open-air laboratory showing how climate change affects biodiversity. Although many studies have independently demonstrated the impact of climate change in the Alps on either the seasonal activity (i.e. phenology) or the migration of plants and animals, no systematic analysis has been carried out on both consequences simultaneously. A European team of ecologists 1 , including Jonathan Lenoir, CNRS Researcher in the research unit Écologie et Dynamique des Systèmes Anthropisés (CNRS/University of Picardie Jules Verne), has just published a review that quantifies seasonal changes and elevational movements of more than 2,000 species of plants, animals and fungi that live in the Alps.
