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。

Tolypothrix limbataはMichaetaceae科に属する偽分枝糸状シアノバクテリアで、窒素固定のための異形細胞を持つ連糸を形成する。湿った土壌・岩石・淡水基質で生育し、栄養貧乏環境の窒素循環に寄与する。保全状況は評価されていない。
