Kopfzystiden-Stachelhaut

Hyphoderma orphanellum is a corticioid fungus in the family Polyporaceae, assessed as Near Threatened (NT). It forms thin, resupinate fruiting bodies on dead wood of broadleaf trees in mature or old-growth forest environments. Its near-threatened status reflects its sensitivity to the removal of deadwood and disturbance of old-growth forests.

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.
