common broomrape

The common broomrape (<em>Orobanche minor</em>) is a parasitic flowering plant with an exceptionally wide global distribution, occurring across Africa, Asia, Europe, North America, Oceania, and South America, and typically inhabiting tropical and subtropical forests and grasslands. This species is classified as Near Threatened on the IUCN Red List, indicating that its populations may be declining in some parts of its range. As a member of the family Orobanchaceae, the common broomrape is a root parasite that attaches to the roots of host plants, most commonly members of the legume and carrot families, from which it draws all of its nutrients. It lacks chlorophyll and therefore cannot photosynthesize, making it entirely dependent on its host for survival. The species often produces spikes of yellowish or purplish tubular flowers above the soil surface during spring and summer across its diverse geographic range. 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。
