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。

Xylaria corniformisは熱帯および亜熱帯林生息地の腐朽木材に硬く角状またはシカの角状の黒い子座を形成する棍棒形の炭質子嚢菌類です。森林生態系において木質セルロースの分解に貢献する腐生性木材分解菌です。絶滅危惧（EN）に分類されており、熱帯の森林破壊と原生林生息地の消失が脅威となっています。
