African elephant

地球上最大の陸上動物であるアフリカゾウは体重7,000 kgに達し、サハラ以南のサバンナ、森林、湿地に生息する。成熟した雌が群れを率いる高度に知的な社会構造を持ち、超低周波音やうなり声、接触によって意思疎通する。木を引き倒したり水飲み場を掘ったり種子を散布したりすることで生態系を形成するエンジニア種だが、象牙の密猟や生息地の喪失により個体数は減少しており、危急（VU）とされている。

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。
