Christmastree

The Christmas tree (Nuytsia floribunda) is a root hemiparasite tree in the family Loranthaceae, endemic to Western Australia. It is the only member of its family to grow as a full-sized tree rather than an arboreal parasite on other trees, reaching heights of up to ten meters. Nuytsia floribunda is a remarkable botanical curiosity: it parasitizes the roots of a wide range of neighboring plants, extracting water and nutrients while also performing its own photosynthesis. The species is well adapted to the nutrient-poor soils of southwestern Australian woodlands and kwongan heath. Its common name derives from the spectacular mass flowering events that occur in late November and December, when the entire canopy becomes covered in brilliant orange-gold flowers, transforming the landscape around the Christmas period. This is considered one of the most spectacular wildflower displays in Australia. The tree is sacred to several Aboriginal peoples of Western Australia. Nuytsia floribunda is generally considered secure within its native range in southwestern Australia, benefiting from its specialized root-parasitic strategy that allows it to access resources from a broad host community. It is an iconic species of the southwestern Australian flora.

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。
