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。

Peniophorella echinocystis は絶滅危惧IA類(CR)と評価された皮質性菌類で、極めて稀少で分布域が非常に限定されている。成熟した老齢林や古代林の枯れ木に薄い伏生の皮膜を形成する。この絶滅寸前の状況は、立ち枯れや倒木のある老齢林の緊急な保全の必要性を強調している。
