Blaugrüner Zärtling

Entoloma querquedula is an agaric fungus in the family Entolomataceae, assessed as Near Threatened (NT). It is found in nutrient-poor, unfertilised grassland and mire habitats that have declined due to agricultural intensification and drainage. Its near-threatened status reflects sensitivity to grassland management changes.

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.
