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。

Suillus amabilisはSuillaceae科に属する菌根性イグチで、特にマツなどの針葉樹と共生関係を形成します。ヌメリのある傘の表面と傘の裏面にひだの代わりに孔を持つ鮮やかな子実体を形成するのがこの属の特徴です。菌根関係は森林生態系における菌類と宿主樹木間の栄養交換に不可欠です。
