Range

Distributed across 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.

Chromosera citrinopallida is a species of waxcap mushroom in the family Hygrophoraceae, found in old-growth grasslands and woodland pastures in Europe. Waxcap fungi of the family Hygrophoraceae are characteristic species of unimproved grasslands that have not been subject to fertilization, plowing, or herbicide application for many decades. These grassland waxcap communities are considered indicators of high ecological value and ancient, undisturbed grassland continuity. The fruiting bodies of Chromosera citrinopallida are small and typically display pale yellowish or citrine coloration, as suggested by the specific epithet. Waxcap grasslands of northern and western Europe, including those in the United Kingdom, Scandinavia, and the Baltic states, support exceptional diversity of fungi including waxcaps, earthtongues, and clavarioid species, and are recognized as priority habitats for conservation. Chromosera citrinopallida, like many specialist grassland fungi, is sensitive to changes in soil chemistry caused by fertilizer application, which alters fungal community composition and eliminates specialist species. The species is likely to have declined alongside the widespread loss of traditional meadow and pasture management across Europe during the twentieth century.

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.
