Common Thorn-Apple

<em>Datura stramonium</em>, the common thorn apple or jimsonweed, is an annual herbaceous plant in the family Solanaceae, believed to be native to Central America or southern North America but now cosmopolitan, occurring in over 90 countries across temperate and tropical regions worldwide. It is Not Evaluated on the IUCN Red List as a widespread weed. The plant grows in disturbed soils, waste ground, roadsides, agricultural fields, and gardens. It bears large, lobed leaves with an unpleasant odor, distinctive white to pale violet trumpet-shaped flowers, and spiny seed capsules. All parts of <em>Datura stramonium</em> are highly toxic, containing tropane alkaloids including scopolamine, hyoscyamine, and atropine, which can cause severe poisoning in humans and livestock. Despite its toxicity, it has a long history of medicinal and ritual use across many cultures. The species is considered an invasive weed in many agricultural contexts. Biological traits such as seed output per plant, precise lifespan, and biomass data remain poorly documented in standardized global assessments.

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。
