Collins' rockcress

<em>Boechera collinsii</em>, commonly known as Collins' rockcress, is a plant species belonging to the genus <em>Boechera</em> within the family Brassicaceae, which includes mustards and related flowering plants. This species has been documented in Canada, where it inhabits diverse terrestrial environments. Members of the genus <em>Boechera</em> are typically herbaceous perennials or biennials adapted to rocky outcrops, cliff faces, talus slopes, and open woodland habitats, often tolerating thin, well-drained soils where competition from other vegetation is limited. The species has not been formally assessed for conservation status by major evaluation bodies. As a flowering plant, <em>Boechera collinsii</em> does not engage in dietary behavior in the traditional sense; it produces energy through photosynthesis and may support pollinators and herbivores as part of its native ecosystem. Biological traits of this species remain poorly documented in the scientific literature. Further botanical surveys in Canadian habitats are needed to clarify the distribution, population status, and ecological interactions of <em>Boechera collinsii</em>.

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。
