Common Fumitory

Fumaria officinalis, commonly known as common fumitory, is an annual herbaceous plant in the family Papaveraceae. It has a very wide global distribution spanning Africa, Asia, Europe, North America, and South America, reflecting its success as a weedy colonizer of disturbed habitats. The species typically grows in cultivated fields, roadsides, gardens, and waste ground, tolerating a broad range of soil types and conditions. Fumaria officinalis produces small pinkish-purple tubular flowers and finely divided, glaucous foliage that gives the plant a delicate, smoke-like appearance — a characteristic reflected in its common name. It is assessed as Least Concern, consistent with its extensive cosmopolitan distribution and abundance in human-modified landscapes. The plant has a long history of use in traditional herbal medicine across parts of its native range. Biological traits of this species remain poorly documented in the scientific literature. Despite its weedy character, Fumaria officinalis provides food resources for certain specialist insects and contributes to ground flora diversity in agricultural and disturbed environments.

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。
