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.

Nodularia litorea is a filamentous, nitrogen-fixing cyanobacterium found in coastal and estuarine environments, tolerating a range of salinities from brackish to marine conditions. It forms short trichomes with alternating vegetative cells and heterocysts. Like other Nodularia species, it may produce hepatotoxins (nodularin) under bloom-forming conditions, posing risks to aquatic life and water quality.

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.
