地球上で生きたことが知られている最大の動物であるシロナガスクジラ（Balaenoptera musculus）は、体長33メートル、体重200トンに達することができ、心臓だけで小型自動車ほどの重さがあります。全ての海洋に生息し、極地の餌場と熱帯の繁殖地の間を回遊します。1日最大4トンのオキアミを摂取する濾過摂食者です。20世紀の捕鯨による絶滅危機からの回復後、世界的な個体数は10,000〜25,000頭と推定される絶滅危惧種です。

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.
