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 Orange Legionnaire

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

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 Orange Legionnaire

<em>Beris vallata</em> is a soldier fly in the family Stratiomyidae, known from Belgium, Denmark, Norway, and Sweden in northern Europe. The species inhabits a broad range of terrestrial and freshwater environments, including woodland edges, hedgerows, stream margins, and moist meadows where decaying organic matter supports larval development. Larvae of Beris species typically develop in rotting wood, leaf litter, damp soil, or organic debris, while adults are often found visiting flowers for nectar and pollen. The IUCN classifies this species as Near Threatened, indicating that it faces meaningful risk factors that could elevate its status if current trends continue. Pressures likely include habitat degradation, loss of traditional woodland management practices, and the decline of dead wood microhabitats essential for larval stages. The species has a restricted distribution confined to northern European countries and may be sensitive to changes in woodland structure and composition. Biological traits such as average lifespan, body length, body weight, and detailed dietary studies remain poorly documented in standardized ecological databases for this dipteran species. Continued monitoring of woodland habitats across its range is important for its long-term conservation.
