cockatoo-apple

The cockatoo apple (Planchonia careya) is a medium to large deciduous tree in the family Lecythidaceae, native to the tropical woodlands, savanna, and monsoon forests of northern Australia, including Queensland, the Northern Territory, and Western Australia, as well as southern New Guinea. Growing to around 15 metres in height, it is characterised by a thick, deeply furrowed bark that provides fire resistance — an important adaptation in fire-prone Australian savannas — and large, glossy leaves that are shed during the dry season. The tree produces spectacular flowers with numerous long white or pale pink stamens in large brush-like clusters, opening briefly at night and falling by morning; these flowers are important nectar sources for flying foxes, nocturnal insects, and brush-tailed possums. The fruits are large, fleshy, and edible, though somewhat acidic; they are consumed by a range of wildlife including cockatoos — to whom the common name refers — as well as emus, feral pigs, and humans. Aboriginal Australians have long used the bark, seeds, and fruit medicinally and as a food source, and the species holds cultural significance in many traditional communities. Planchonia careya is classified as Least Concern by the IUCN, with stable populations across its wide Australian range. It is sometimes cultivated as a shade and ornamental tree in tropical and subtropical gardens.

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。
