ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

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.
