Branchinecta paludosa are then reproductive for 35–45 days. 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
Novaya Zemlya avalanche that blocked two glacial streams and created a lake in length. Over its history as a nuclear test site, Novaya Zemlya hosted 224 nuclear detonations with a total explosive energy equivalent to 265 megatons of TNT. For comparison, all explosives used in World War II, including the detonations of two US nuclear bombs, amounted to only two megatons. In 1988–1989, "glasnost" helped make the Novaya Zemlya testing activities public knowledge, and in 1990 Greenpeace activists staged a protest at the site. The last nuclear test explosion was in 1990 (also the last for the entire Soviet Union and Russia).
