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。

wild boar

家豚の祖先であるイノシシは最大200kgに達する頑強な雑食性の有蹄類で、西ヨーロッパからアジア、北アフリカまで森林、湿地、草原などさまざまな生息地に分布します。高い適応性と旺盛な繁殖力により、北アメリカやオーストラリアなど多くの地域で侵略的外来種となっています。土を掘り返す習性により土壌と植生を攪乱し、森林構造と種子の発芽に大きな影響を与えます。
