Walzensporiger Fälbling

Hebeloma cylindrosporum is an agaric fungus in the family Hymenogastraceae, assessed as Data Deficient (DD). It forms ectomycorrhizal associations with conifers and has been widely used in laboratory studies of mycorrhizal physiology. Limited field occurrence data make a precise conservation assessment difficult.

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.
