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。

Volvariella caesiotinctaはPluteaceae科に属する担子菌類で、危急種(VU)と評価されています。枯死木質材料上に生育し、成熟時に托(Volva)とピンク色のひだが特徴的です。危急種としての状況は生息地の損失と管理された景観における適切な腐朽木の希少性を反映しています。
