Range

Found in Cuba.

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.

Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Coast Indigo

Coast indigo (Indigofera miniata) is a perennial herb or subshrub in the family Fabaceae, native to the coastal scrub, pine barrens, and sandy grasslands of Cuba and the broader Caribbean region. Like other members of the genus Indigofera, it produces compound pinnate leaves and racemes of small, pea-type flowers, though in this species the flowers are notably small and pinkish to reddish. The genus Indigofera is best known for Indigofera tinctoria, the source of natural indigo dye, but most species including Indigofera miniata have not been commercially exploited for dye production. Coast indigo grows in open, sunny, often disturbed habitats including sandy coastal plains, roadsides, and degraded scrubland, benefiting from its ability to fix atmospheric nitrogen through root nodule bacteria—a common trait in the legume family. The IUCN assesses it as Least Concern, reflecting its ability to persist in disturbed and marginal coastal habitats across the Caribbean. Regional populations are affected by coastal development and vegetation clearance but are not considered globally threatened.

Polar bear

地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
