Canadian beaver

北米最大の齧歯類であるカナダビーバーは体重32kgにも達し、カナダ・米国北部の河川、湖沼、湿地に生息する優れた生態系エンジニアです。木を倒して数百メートルに及ぶダムを造ることで池を形成し、数百種の生息環境を提供します。その巣穴や運河は流域全体を変化させます。かつては毛皮のために絶滅寸前まで狩られましたが、個体数は大きく回復しています。

コウテイペンギン

世界最大のペンギンであるコウテイペンギン(Aptenodytes forsteri)は体高最大1.2m、体重45kgで、地球上で最も過酷な環境の一つである南極大陸に生息しています。零下60°C以下の真冬の暗闇の中で繁殖し、雌が海上にいる間、雄が65日間足の上で育雛嚢の下に一つの卵を温め続けます。数千羽からなる群れで個体が暖かい中心部を循環するいわゆるハドリング行動は、協調的な生存戦略の傑作です。
