Range

Distributed across Finland, Iceland, Norway, and Sweden. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Polar bear

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.

Clustered Sedge

Carex glareosa, the clustered sedge or gravel sedge, is a perennial sedge in the family Cyperaceae distributed across the circumpolar Arctic and subarctic zones of the northern hemisphere, growing in coastal and inland wetlands, salt marshes, brackish meadows, mudflats, gravelly tundra, and low-lying areas subject to periodic flooding. The species forms dense tufts or loose colonies, producing narrow, grass-like leaves and small spikelets characteristic of the genus Carex. C. glareosa is adapted to saline and brackish conditions in coastal habitats, as well as to freshwater wetlands in more continental settings. Like other Arctic sedges, it is an important component of tundra and wetland plant communities that provide habitat and forage for migratory waterfowl, shorebirds, and Arctic mammals. The species is listed as Vulnerable by the IUCN, with concern focused on the impacts of climate change on Arctic and subarctic wetland habitats, where rising temperatures, permafrost thaw, altered hydrology, and increased shrub encroachment threaten specialized wetland plant communities.

Polar bear

O maior carnivoro terrestre da Terra, o urso-polar pode ultrapassar 700 kg e e encontrado pelo gelo marinho artico, do Canada ate a Russia. Mamiferos marinhos altamente especializados que dependem do gelo marinho para cacas de focas e focas-barbadas. Excelentes nadadores capazes de percorrer grandes distancias em aguas abertas. Classificado como Vulneravel, com populacoes sob severa pressao devido a rapida perda de gelo marinho artico causada pelas mudancas climaticas.
