Habitat & Geographic Range
Coast Coral Tree
Typically found in diverse terrestrial habitats from tropical forests to temperate regions.
Found in Taiwan.
Polar bear
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 Coral Tree
Coast coral tree (Erythrina caffra) is a large, semi-deciduous tree in the family Fabaceae, native to the subtropical coastal forests and riparian zones of the eastern coast of South Africa and coastal Mozambique. It grows in coastal dune forest, riverine forest margins, and rocky hillsides near the sea, often becoming a prominent canopy tree in coastal forest. The trunk is covered in distinctive corky, spiny bark; branches are armed with short thorns; and spectacular clusters of bright red, tubular flowers are produced before or with the new leaves in late winter and spring, providing an important nectar source for sunbirds and other nectarivores. Fruit pods are long, woody, and contain bright red seeds. Coast coral tree is widely planted as a street tree, shade tree, and garden specimen across subtropical coastal cities and is the official tree of Durban, South Africa. It is assessed as Least Concern by the IUCN. Historically, various parts of the tree were used medicinally by Zulu and Xhosa communities. In cultivation it has naturalised in Hawaii and other tropical regions.
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。
