Habitat & Geographic Range
Common bamboo
Typically found in grasslands, wetlands, forests, and cultivated landscapes.
Widely distributed across Africa (18 countries), Asia (4 countries), Europe (Italy), North America (9 countries), Oceania and the Pacific (5 countries), and South America (5 countries).
Polar bear
Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.
Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.
Common bamboo
世界で最も広く栽培されている竹種の一つであるリュウチク(真竹)は、最適な条件下で1日最大91cmという驚異的な速度で成長し、アジア、アフリカ、アメリカの熱帯・亜熱帯地域に分布します。技術的には樹木ではなく巨大な草であるこの種の稈は20メートルに達し、建設、紙、繊維、食品のための急速更新可能な木材代替品を提供します。竹林に依存するジャイアントパンダを含む野生生物の重要な生息地構成要素です。
Polar bear
地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
