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。

Psathyrella sphagnicolaはPsathyrellaceae科に属する小型で脆いキノコで、絶滅危惧(EN)と評価されている。泥炭湿地や湿原生息地でミズゴケと関連して生育し、これらの生息地は排水と土地転換によって大幅に減少している。絶滅危惧状態は未撹乱の湿原生態系の深刻な損失を反映している。
