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。
Polar bear
地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
