A circumpolar distribution is any range of a taxon that occurs over a wide range of longitudes but only at high latitudes; such a range therefore extends all the way around either the North Pole or the South Pole. [1] [2] Taxa that are also found in isolated high-mountain environments further from the poles are said to have arctic–alpine distributions. [3]
Animals with circumpolar distributions include the reindeer, [1] [2] polar bear, [4] Arctic fox, [1] [5] snowy owl, [5] snow bunting, [5] king eider, [5] brent goose [5] and long-tailed skua [5] in the north, and the Weddell seal [1] and Adélie penguin [1] in the south.
Plants with northern circumpolar distributions include Eutrema edwardsii (syn. Draba laevigata), [2] Saxifraga oppositifolia, [3] Persicaria vivipara [6] and Honckenya peploides. [7] [8] [9]
