Branchinecta paludosa Branchinecta paludosa Branchinecta paludosa is a species of fairy shrimp with a Holarctic distribution. "B. paludosa" is widely distributed in the Arctic tundra of Eurasia, chiefly above latitudes of 60° north. It reaches its northern limit, 77° north at Ivanov Bay in the Novaya Zemlya archipelago. Further populations exist as far south as the Tatra Mountains on the Polish–Slovakian border at about 49° north. There are scattered records from North America, mostly near the Arctic Ocean. After hatching, young "B. paludosa" spend 20–30 days as larvae, before reaching sexual maturity between the end of July and middle of August. They
Baltica for example, the curved margin north of the Urals running parallel to Novaya Zemlya was probably deformed during the eruption of the End-Permian Siberian Traps. Baltica's western margin is the Caledonide orogen which stretches northward from the Scandinavian Mountains across Barents Sea to Svalbard. Its eastern margin is the Timanide orogen which stretches north to the Novaya Zemlya archipelago. The extent of the Proterozoic continent are defined by the Iapetus Suture to the west; the Trollfjorden-Komagelva Fault Zone in the north; the Variscan-Hercynian suture to the south; the Tornquist Zone to the southwest; and the Ural Mountains to the east.
