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.

koala

オーストラリア東部・南東部を代表する有袋類で、体重は最大15kgに達し、低カロリーのユーカリの葉食から得るエネルギーを節約するために1日最大22時間を睡眠に費やす。他の哺乳類の多くを死に至らしめる有毒なユーカリ成分を処理するために高度に特化しており、解毒に特別に適応した腸内微生物叢を持つ。クラミジア感染症、生息地の伐採、気候変動により個体数が激減し、2022年に絶滅危惧種に指定された。
