Coliseum-Ivy

<em>Cymbalaria muralis</em>, commonly known as Coliseum Ivy or Kenilworth Ivy, is a trailing flowering plant in the family Plantaginaceae. It has not been formally assessed under the IUCN Red List. The species has a wide global distribution, documented in Africa, Asia, Europe, North America, Oceania, and South America, with specific country records including Albania, Australia, Belarus, Belgium, and Brazil. Originally native to the Mediterranean region of southern Europe, it has spread widely and often naturalizes on stone walls, rocky surfaces, and pavements. The plant is characterized by small, lobed leaves and tiny purple-and-yellow flowers resembling miniature snapdragons. An interesting adaptation of <em>Cymbalaria muralis</em> is its phototropic behavior: the flower stalks bend toward light during flowering to facilitate pollination, then turn away from light after fertilization, directing developing seed capsules into crevices in walls where seeds can germinate. Population estimates, population trend, diet, and biological measurements are not documented in available 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。
