Chromosera citrinopallida is a species of waxcap mushroom in the family Hygrophoraceae, found in old-growth grasslands and woodland pastures in Europe. Waxcap fungi of the family Hygrophoraceae are characteristic species of unimproved grasslands that have not been subject to fertilization, plowing, or herbicide application for many decades. These grassland waxcap communities are considered indicators of high ecological value and ancient, undisturbed grassland continuity. The fruiting bodies of Chromosera citrinopallida are small and typically display pale yellowish or citrine coloration, as suggested by the specific epithet. Waxcap grasslands of northern and western Europe, including those in the United Kingdom, Scandinavia, and the Baltic states, support exceptional diversity of fungi including waxcaps, earthtongues, and clavarioid species, and are recognized as priority habitats for conservation. Chromosera citrinopallida, like many specialist grassland fungi, is sensitive to changes in soil chemistry caused by fertilizer application, which alters fungal community composition and eliminates specialist species. The species is likely to have declined alongside the widespread loss of traditional meadow and pasture management across Europe during the twentieth century.

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。
