Chromosera xanthochroa is a waxcap mushroom in the family Hygrophoraceae, associated with old, unimproved grasslands in Europe. Like other members of the genus Chromosera and the broader waxcap community, it is considered an indicator of ecologically ancient grassland that has escaped agricultural intensification. The specific epithet xanthochroa refers to yellow or golden coloration, which is a feature of this species' fruiting bodies. Waxcap species are mycorrhizal or saprotrophic fungi that develop slowly over years to decades in stable grassland soils undisturbed by plowing, reseeding, or fertilizer application. The presence of rich waxcap communities — including multiple Chromosera, Cuphophyllus, Hygrocybe, and Camarophyllopsis species — is internationally recognized as a signal of extraordinary grassland biodiversity value. Countries such as Wales, Ireland, Norway, Sweden, and Estonia hold globally significant concentrations of waxcap grasslands. Chromosera xanthochroa faces pressures from habitat loss driven by agricultural intensification, development, and succession of grassland to scrub and woodland following cessation of traditional grazing. Conservation of waxcap grassland sites requires continuation of low-intensity pastoral management.

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。
