Populations are also found in montane and highland environments at higher elevations.

Range

Found in Norway. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Birken-Gürtelfuß

Cortinarius bivelus is a mycorrhizal agaric fungus in the family Cortinariaceae, assessed as Data Deficient (DD). Like other members of the genus, it forms ectomycorrhizal associations with forest trees and produces a characteristic cobweb-like cortina veil when young. Insufficient data on its distribution and population size prevent a reliable conservation assessment.

Kaiserpinguin

The world's largest penguin, emperor penguins stand up to 1.2 meters and weigh 45 kg, inhabiting the Antarctic continent in some of the most extreme conditions on Earth. They breed in midwinter darkness at temperatures below -60°C, with males incubating single eggs on their feet under a brood pouch for 65 days while females are at sea. Their huddling behavior — cycling individuals through the warm center of thousands-strong groups — is a masterclass in cooperative survival.
