Lichenomphalia velutinaは、藻類を含む粒状の葉状体と小型で黄褐色〜黄緑色のキノコ型子実体を持つ地衣化担子菌類です。北欧と北米の北方林や高山環境において、苔の多い泥炭質土壌や酸性湿地に生息します。この特異な生物は地衣化とキノコ形成を組み合わせて栄養を獲得します。

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。
