Habitat & Geographic Range

Bely Medved

Habitat

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.

Range

Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Nitrosotalea is a genus of ammonia-oxidizing archaea in the phylum Thaumarchaeota, distinguished by their ability to perform nitrification under acidic conditions where most other nitrifying microorganisms cannot survive. Species within this genus have been detected in acidic soils worldwide, suggesting a significant but underappreciated role in nitrogen cycling in low-pH habitats. The genus was established following the cultivation of the type species from agricultural soil.

Bely Medved

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.
