Range

Distributed across Belgium, Denmark, Norway, and Sweden. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Eisbär

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.

Glatter Braunsporstacheling

Sarcodon leucopus is a tooth fungus producing a fleshy, brownish cap studded with pale spines (teeth) on its underside instead of gills or pores. It forms ectomycorrhizal associations with conifers and broadleaf trees in European temperate and boreal forests. Near Threatened, this species is sensitive to nitrogen deposition and the loss of old-growth forest habitats.
