Common Ivy

<em>Hedera helix</em>, commonly known as common ivy or English ivy, is a woody evergreen climber and groundcover in the family Araliaceae. It is classified as Least Concern on the IUCN Red List, with a very wide global distribution across the Palearctic realm and beyond, encompassing temperate and Mediterranean habitats. The species is native to Europe and western Asia and has been widely introduced elsewhere. It typically grows in woodlands, hedgerows, cliffs, walls, and urban green spaces, tolerating deep shade and a wide range of soil conditions. Common ivy provides important ecological services, offering shelter and late-season nectar and fruit resources for wildlife. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.

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。
