Habitat & Geographic Range

Bamboo bear

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate coniferous forests, and temperate broadleaf and mixed forests, among 7 distinct biome types spanning the Indomalayan and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Found in China. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Liverwort

Habitat

Native to Asia and Europe and North America, inhabiting ecosystems characteristic of the region.

Range

Widely distributed across Asia (Taiwan), Europe (6 countries), North America (United States), and South America (Brazil, Chile, Colombia).

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。

Common Liverwort

<em>Marchantia polymorpha</em>, the common liverwort, is a thalloid bryophyte in the family Marchantiaceae and one of the most cosmopolitan non-vascular plants on Earth. It is found across Asia, Europe, North America, and South America, typically colonizing moist, shaded habitats such as stream banks, damp soil, rock surfaces, and disturbed ground. The common liverwort reproduces both sexually, producing umbrella-shaped reproductive structures called gametangiophores, and asexually through small disc-shaped gemmae produced in cup-shaped gemma cups on the thallus surface. Its flat, ribbon-like thallus with a distinct midrib is a recognizable feature of this species. The species has not been formally evaluated by the IUCN due to its wide distribution and abundance. Marchantia polymorpha is a model organism in plant biology, widely used in laboratory research to understand plant evolution, development, and genetics. It is one of the earliest diverging lineages of land plants, providing valuable insights into the evolutionary transition from aquatic to terrestrial environments.
