Clavariadelphus helveticus is a club fungus in the family Gomphaceae, distinguished by its simple, unbranched fruiting bodies that emerge singly or in small clusters from forest soils. The genus Clavariadelphus comprises robust, fleshy, clavate fungi with smooth to slightly wrinkled surfaces, typically growing in association with coniferous or mixed forest trees through ectomycorrhizal relationships. Clavariadelphus helveticus in particular is associated with montane forests of central Europe, particularly the Alps and adjacent mountain ranges where it was first described. The fruiting bodies are generally pale buff to ochre or pinkish-buff, broadening toward the apex and tapering toward the base, reaching several centimeters in height. The flesh is firm and white, lacking the distinctive bitter taste of some related species. Spore dispersal occurs from the smooth to slightly roughened surface of the club. The species fruits in late summer to autumn, typically after periods of rainfall. Ectomycorrhizal club fungi contribute to forest nutrient cycling by facilitating mineral and water uptake in tree roots. Population dynamics of Clavariadelphus species are sensitive to forest management practices, soil disturbance, and climate-driven shifts in tree community composition. The conservation status of Clavariadelphus helveticus has not been formally assessed globally, though club fungi as a group are considered indicators of old-growth forest quality in European red-list assessments.

koala

オーストラリア東部・南東部を代表する有袋類で、体重は最大15kgに達し、低カロリーのユーカリの葉食から得るエネルギーを節約するために1日最大22時間を睡眠に費やす。他の哺乳類の多くを死に至らしめる有毒なユーカリ成分を処理するために高度に特化しており、解毒に特別に適応した腸内微生物叢を持つ。クラミジア感染症、生息地の伐採、気候変動により個体数が激減し、2022年に絶滅危惧種に指定された。
