Christmasbush

Christmasbush (Chromolaena odorata) is a fast-growing perennial shrub in the family Asteraceae, native to tropical and subtropical regions of the Americas. Outside its native range, it is one of the world's most problematic invasive plant species, having established across large areas of Africa, Asia, and the Pacific. It produces abundant small, pale lavender to white flower heads in dense clusters and is well adapted to disturbed habitats, roadsides, forest margins, and abandoned agricultural land. The species grows rapidly following disturbance, forming dense thickets that exclude native vegetation and can dramatically alter local plant communities. Chromolaena odorata is fire-adapted and can increase fire intensity in invaded ecosystems, disrupting native fire regimes. It is a significant agricultural weed, colonizing plantations and reducing productivity. The plant has allelopathic properties, releasing chemical compounds that inhibit the germination and growth of neighboring plants. Despite its invasive status in many regions, Chromolaena odorata has some documented traditional medicinal uses in parts of Africa and Asia, though these do not offset its negative ecological impacts. Control of the species typically involves a combination of mechanical removal, herbicide application, and biological control agents.

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。
