Ardilla Gris Oriental
ヒガシハイリス(Sciurus carolinensis)は北米東部原産の中型樹上性げっ歯類で、ヨーロッパをはじめ世界各地に移入された外来種である。IUCNレッドリストでは軽度懸念(LC)に分類されており、都市公園や郊外の森林環境への適応力が高く、堅果の埋蔵行動が植物の種子散布に重要な役割を果たしている。英国ではニホンリスを食物競争で駆逐しており、侵略的外来種としても問題視されている。
Bamboo bear
ジャイアントパンダ(Ailuropoda melanoleuca)は中国中部の山岳竹林に生息し、体重最大125キログラムになるクマ科の動物で、食肉目に分類されながら食事の99%を竹が占める特異な食性を持つ。偽の親指(橈側種子骨)を使って竹の茎を把握し、1日14時間もの採食時間を費やす。2016年にIUCNレッドリストで絶滅危惧から危急(VU)へ改善されており、保護繁殖プログラムと自然保護区の設置が個体数回復に貢献している。
