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.

コウテイペンギン

世界最大のペンギンであるコウテイペンギン（Aptenodytes forsteri）は体高最大1.2m、体重45kgで、地球上で最も過酷な環境の一つである南極大陸に生息しています。零下60°C以下の真冬の暗闇の中で繁殖し、雌が海上にいる間、雄が65日間足の上で育雛嚢の下に一つの卵を温め続けます。数千羽からなる群れで個体が暖かい中心部を循環するいわゆるハドリング行動は、協調的な生存戦略の傑作です。
