арктоальпийский

arctoalpine, arctic-alpine Such animals and plants are called arctic-alpine species. This alpine zone in many ways bears a close resemblance to the arctic region, but it differs in several ways, including light conditions (no midnight sun) and lower barometric pressure, so that it is generally not incorporated in the arctic region. Treeless alpine zones exist also in the isolated high mountains farther south, as in the Alps and the Pyrenees, and they also are inhabited by some arctic-alpine species.
