gray wolf

最も広い分布域を持つ野生のイヌ科動物であるハイイロオオカミは、北アメリカからユーラシアにかけてのツンドラ、森林、草原などの多様な生息地に分布します。優位な繁殖ペアに率いられた家族単位の群れで生活する高度に社会的な動物です。キーストーン捕食者として獲物個体群を調整し、生態系の構造を根本的に形成することは、イエローストーンでの再導入により実証されています。かつて激しく迫害されましたが、多くの地域で個体群は回復しつつあります。

house mouse

地球上で最も広く分布し個体数が多い哺乳類の一つであるハツカネズミは南アジアを起源とし、南極大陸を除くすべての大陸に人類文明とともに広まった。体重わずか15〜25gで、最小限の食物と水で生存できる高度に適応した雑食性動物である。世界で最も一般的に使用される実験動物として、生物医学研究のほぼすべての分野に貢献してきた。世界的に農業に多大な被害を与える。
