Common teatree

<em>Leptospermum petersonii</em>, the lemon-scented teatree, is a shrub or small tree in the family Myrtaceae, native to eastern Australia but noted in distribution records including the Democratic Republic of Congo and the United States, reflecting its cultivation and occasional naturalization in tropical and subtropical regions. It is classified as Least Concern on the IUCN Red List. The plant is prized for its strongly lemon-scented foliage, which yields an essential oil used in perfumery and aromatherapy. It typically grows as a dense, multi-stemmed shrub reaching 3–6 meters tall, bearing small, narrow leaves and white or pale pink five-petaled flowers. Like other teatrees, it is adapted to well-drained, often nutrient-poor soils and full sun conditions. The flowers attract bees and other pollinators. It is sometimes cultivated as an ornamental and for essential oil production. Biological traits such as precise lifespan, seed output, and biomass measurements remain poorly documented in standardized scientific assessments for this species.

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。
