brown bear

世界で最も広く分布するクマ科の種であるヒグマ（Ursus arctos）は、北アメリカとヨーロッパからロシアを経て日本まで、森林、ツンドラ、高山草原を占有します。成体はアラスカの沿岸個体群では最大700kgまで体重が増えることがあります。果物、根、魚、腐肉を食べる雑食動物で、ヒグマは景観全体に栄養素を分配するキーストーン種です。ほとんどの個体群は安定していますが、一部の亜種は脅威にさらされています。

Cheetah

地球上で最も速い陸上動物で、アフリカとイランの草原において短距離走で時速112kmに達する。深い胸部、長い脚、独特の黒い涙縞模様を持つ細身の体型が特徴だ。他の大型ネコ科動物とは異なり、チーターはチャープ音やパー音で鳴く。生息地の分断と大型捕食者との競争により、残存個体数は約7,000頭のみとなっており、危急種に分類されている。
