Common Water Forget-Me-Not

<em>Myosotis scorpioides</em>, commonly known as the common water forget-me-not, is a perennial wetland herb belonging to the family Boraginaceae. It is classified as Least Concern by the IUCN and has a broad distribution across Europe, Asia, and North America, where it has been widely naturalized. The species typically grows along the margins of slow-moving rivers, streams, ditches, ponds, and marshes, rooting in wet mud or shallow water. It is a low-growing plant with elongated, softly hairy leaves and produces the characteristically small sky-blue flowers with yellow centers arranged in curved cymes that unfurl as new blooms open — a feature called scorpioid inflorescence, which gives the plant its scientific epithet. Flowering typically occurs from late spring through summer, attracting a variety of small pollinators including bees and hoverflies. <em>Myosotis scorpioides</em> spreads through both seed dispersal and creeping stolons, allowing it to form dense mats in favorable wetland habitats. Biological traits including average lifespan, height, and mass remain poorly documented in standardized databases, though the plant typically reaches 20–40 cm in height. Ecologically, the common water forget-me-not contributes to riverbank stabilization and provides cover and foraging habitat for wetland invertebrates. It is also widely cultivated as an ornamental plant in water garden settings across its native and introduced range.

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。
