Range

Distributed across Denmark, Norway, Sweden, and United States.

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。

Collybia Clouds

Syzygospora mycetophila, commonly known as Collybia Clouds, is a fungal species belonging to the genus Syzygospora. This species is notable for being a mycoparasite, meaning it parasitizes other fungal fruiting bodies rather than obtaining nutrients from plant material or decaying organic matter directly. It has been documented across Europe and North America, with records from Denmark, Norway, and Sweden in Europe, and the United States in North America. The species typically grows on or near mushrooms of other species, particularly members of the former genus Collybia, forming distinctive white, cloud-like or granular growths on the host fruiting bodies. This unusual ecological strategy places it among a relatively small group of fungi that have evolved parasitic relationships with other fungi. Its conservation status has not been formally evaluated. Dietary behavior in the conventional sense is replaced by its parasitic nutrient acquisition from host fungi. Biological traits of this species remain poorly documented in the scientific literature. Syzygospora mycetophila is primarily encountered by mycologists surveying woodland habitats where its host fungi are abundant.
