Habitat

Native to Europe and North America, inhabiting ecosystems characteristic of the region.

Range

Distributed across Norway and United States.

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.

Common Antler Lichen

<em>Pseudevernia consocians</em>, commonly known as Common Antler Lichen, is a foliose or fruticose lichen in the family Parmeliaceae. This species has not been formally evaluated by the IUCN and occurs in countries including Norway and the United States. As a lichen, Common Antler Lichen represents a symbiotic association between a fungal partner (mycobiont) and one or more photosynthetic partners (photobiont), typically green algae or cyanobacteria. It typically grows on the bark of trees or on rocky substrates in temperate and boreal environments, often in well-lit forest edges or open woodland habitats. The branching, antler-like thallus gives the species its evocative common name. Like many lichens, it is often sensitive to air quality and may serve as a bioindicator of environmental health, being negatively affected by elevated levels of nitrogen and sulfur dioxide pollution. Biological traits of this species remain poorly documented in the scientific literature.

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.
