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。

Rhodocollybia prolixa は淡褐色の傘と長い繊維質の柄を持つ腐生性キノコで、温帯ヨーロッパの森林内の枯葉層や木質残骸上に生育する。森林床の有機物分解に貢献する。脆弱(VU)に分類されているこの種は、生息地の喪失と有機落葉の堆積を減らす林業管理の変化によって脅かされている。
