Zweihäusiges Sternmoos

Mnium lycopodioides is a leafy moss in the family Mniaceae, one of the larger and more conspicuous moss genera in the northern hemisphere. The name lycopodioides refers to the resemblance of the erect stems to those of clubmoss (Lycopodium) plants, with their regularly arranged, relatively large leaves. Mniaceae mosses typically have large, bordered, toothed leaves arranged in an erect to ascending posture, making them among the most easily recognizable mosses in the field. M. lycopodioides grows on moist mineral soils, rotting logs, and rock faces in boreal and temperate forests across a circumboreal distribution, occurring in northern Europe, Asia, and North America. It favors shaded, humid environments with adequate moisture year-round. Mniaceae species are important components of the boreal and temperate forest floor, contributing to moisture retention and providing microhabitats for soil invertebrates. The species is classified as Least Concern by the IUCN given its wide distribution and relatively abundant occurrence in intact boreal and montane forest habitats.

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.
