Common asparagus fern

<em>Asparagus setaceus</em>, commonly known as Common Asparagus Fern or Lace Fern, is a climbing or sprawling perennial plant in the family Asparagaceae. Despite its common name, it is not a true fern but a flowering plant with feathery, fern-like cladodes that give it a delicate, lacy appearance. This species has not been formally evaluated by the IUCN and is widely distributed across Africa, Asia, Europe, North America, Oceania, and South America. Native to southern Africa, it has been widely introduced globally through horticulture and can become invasive in some regions. Common Asparagus Fern typically grows in a range of habitats including grasslands, wetland margins, and forest edges, often using its small hooks to climb over other vegetation. Small white or pinkish flowers are followed by dark berries that attract birds, facilitating seed dispersal. It is valued as an ornamental plant for its feathery foliage and is commonly used in floral arrangements. 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。
