Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

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.

Clay Crest

Clay-crest, Malacothrix saxatilis, is a perennial herb in the family Asteraceae native to coastal bluffs, chaparral, and rocky slopes of California and Baja California in the western United States and Mexico. The species forms sprawling to semi-erect stems with deeply lobed, grayish-green leaves and bears numerous pale white to cream-colored, dandelion-like flower heads with finely fringed ray florets. The common name refers to the chalky or clay-colored appearance of the foliage, which has a grayish, mealy texture due to fine pubescence. Clay-crest is characteristic of dry, rocky habitats, particularly coastal sage scrub and chaparral communities on calcium-rich soils of the California Floristic Province, one of the world's recognized biodiversity hotspots. The species is drought-tolerant, producing much of its growth and flowering during the cooler, wetter months of the California winter and spring before entering summer dormancy. Pollinators including bees and butterflies visit the flowers. Malacothrix saxatilis has several recognized varieties adapted to slightly different microhabitats along the Pacific coast. The species is not currently listed as threatened at the global level, though coastal development and habitat fragmentation threaten some local populations within the California Floristic Province.

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.
