Habitat & Geographic Range

Chucanti Salamander

Habitat

Typically found in freshwater habitats, moist forests, and wetlands.

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.

Chucanti Salamander

The Chucantí Salamander (Bolitoglossa chucantiensis) is a Critically Endangered plethodontid salamander known from the Chucantí mountain massif in the Darien region of eastern Panama. The genus Bolitoglossa represents the largest genus of salamanders globally, with the greatest diversity in Central and South America. B. chucantiensis was described from a small area of cloud forest at mid-to-high elevations in the Serranía de Majé range, an isolated and poorly surveyed mountain system in the Darién Province. Its Critically Endangered status reflects an extremely restricted range (estimated area of occupancy potentially under 10 km²), ongoing deforestation threatening its cloud forest habitat from agricultural expansion and cattle ranching, and the threat of chytridiomycosis, the amphibian fungal disease that has devastated salamander and frog populations across the Americas. Like other Bolitoglossa species, it is a direct-developing salamander that bypasses a free-swimming larval stage, laying eggs in moist terrestrial habitats. Conservation of the Chucantí Nature Reserve, established partly to protect the biodiversity of this mountain, is critical for the survival of this species.

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.
