アルトニア・カルカレア(Arthonia calcarea)は石灰岩・石灰質岩面・古いモルタルに着生する痂状地衣類で、薄い白〜灰色の葉状体に小型の暗色子嚢盤を形成する。IUCNレッドリストでは準絶滅危惧(NT)に分類されており、生育地の攪乱・大気汚染・石灰質石造物の除去により減少傾向にある。安定した石灰質基質と清浄な大気を必要とする生態学的に要求の高い種である。

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。
