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.

Epaulard

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
