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 Tarcrust

Habitat

Native to Europe, inhabiting ecosystems characteristic of the region.

Range

Distributed across Belgium, Denmark, Norway, Portugal, and Sweden.

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 Tarcrust

<em>Diatrype stigma</em>, the common tarcrust, is a saprotrophic fungus in the family Diatrypaceae, found across Belgium, Denmark, Norway, Portugal, and Sweden, as well as more broadly in Europe and temperate regions globally. It grows as a crust-like, charcoal-black stromata on the dead bark and branches of deciduous hardwoods, particularly hazel, beech, and alder. The fruiting bodies are typically flat to slightly raised, dark gray to black patches that contain numerous embedded perithecia in which ascospores are produced. This fungus plays an important ecological role as a decomposer, breaking down dead woody material and recycling nutrients in forest ecosystems. It is Not Evaluated on the IUCN Red List; given its broad distribution on common substrates, it is generally considered widespread. The species reproduces via wind-dispersed ascospores released from the perithecia. Diet, as a saprotrophic organism, consists of dead organic woody matter. Biological traits such as colony growth rates, spore output, and longevity remain poorly documented in standardized quantitative assessments.
