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。

Psilocybe liniformansはシロシビン含有属であるPsilocybeに属する小型の褐色キノコで、ヨーロッパと北アメリカの芝生、牧草地、路傍などの草地生息地に生育する。損傷時に青変反応を示し、これは向精神性化合物の存在を示す。絶滅危惧(EN)に分類され、生息地の喪失と未改良草地生息地の劣化から脅威を受けている。
