Habitat & Geographic Range
Eisbär
Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.
Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.
Natrinema versiforme is an extremely halophilic archaeon in the family Halobacteriaceae characterized by its variable cell morphology, which can range from rods to irregular forms under different salinity conditions. It inhabits hypersaline environments such as salt lakes, salt mines, and salt marshes. Like other haloarchaea, it requires high salt concentrations for membrane and protein stability.
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.
