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
Mirage of astronomical objects sunset occurs slightly later than actual sunset. In ordinary atmospheric conditions, the setting or rising Sun appears to be about half a degree above its geometric position. But sometimes, very unusual atmospheric circumstances can make it to be visible when it is really between two and five degrees below the horizon. This is called the Novaya Zemlya effect, because it was first observed in Novaya Zemlya, where the Sun was seen when, according to astronomical calculations, it should have been two degrees below the horizon. However, it should be noted that due to changes in air pressure, relative humidity, and
