Edelkastanien-Stromabecherling

Ciboria americana is a small, brown, cup-shaped discomycete growing on decaying plant substrates including catkins, acorns, and cones in temperate North American forests. It inhabits forest floors where mast material from oaks, alders, and related trees accumulates. This saprotrophic ascomycete decomposes hard, persistent plant reproductive structures.

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.
