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。

Lecanographa lynceaは、原生林の古い老齢木の樹皮上に生育する希少な固着地衣類です。細長い線形子嚢盤を形成し、ヨーロッパにおいて未撹乱の長期継続性森林生態系を示す最も敏感な指標種の一つとされています。絶滅寸前（CR）に分類され、生息地の喪失、老齢木の衰退、大気汚染により深刻な脅威にさらされています。
