Clovenlip toadflax

Clovenlip toadflax refers to a flowering plant in the genus Linaria (family Plantaginaceae, formerly Scrophulariaceae) distinguished by the characteristic two-lipped or cloven flower structure typical of the toadflax genus. Toadflaxes produce snapdragon-like flowers with an upper and lower lip structure, an orange-tipped palate closing the throat of the corolla, and a long nectar spur at the base of the corolla tube. The clovenlip epithet likely references an especially pronounced or distinctly divided lip structure in this species compared to typical toadflaxes. Linaria species inhabit a range of open, often disturbed habitats including rocky slopes, sandy soils, old walls, dry grasslands, and roadsides across Europe, the Mediterranean region, and western Asia. Several annual and perennial species are known for their rapid colonization of disturbed ground. The flowers of many Linaria species are pollinated by bumblebees strong enough to force open the closed throat, rewarding them with nectar from the spur. Some toadflax species are considered agricultural weeds in cereal crops and disturbed habitats, while others are prized as wildflowers and garden ornamentals.

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。
