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.

Luteimonas padinae is a yellow-pigmented, Gram-negative bacterium first isolated from the brown alga Padina in marine environments. It inhabits coastal marine habitats, particularly in association with macroalgae. This aerobic chemoheterotroph degrades organic compounds derived from algal tissues and marine organic matter.

Polar bear

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.
