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。

Coccomyces coronatus is a discomycete fungus in the family Rhytismataceae, a group of ascomycetes specialized in the colonization and decomposition of dead plant material, particularly fallen leaves and decaying vegetation in temperate woodland ecosystems. The genus Coccomyces encompasses numerous species that produce small, inconspicuous apothecia—the cup-shaped or disc-shaped sexual fruiting bodies characteristic of discomycetes—embedded in or erupting from the surfaces of decaying leaves and plant debris. Coccomyces coronatus has been documented from European temperate forests, where it colonizes the dead leaves of deciduous trees, contributing to the decomposition of leaf litter and the cycling of nutrients back into the soil ecosystem. The fruiting bodies are typically dark, disc-shaped, and minute, often requiring hand lens or microscopic examination to observe in detail. Like other rhytismatacean fungi, C. coronatus produces ascospores that are discharged from the asci within the apothecium and dispersed by air currents or water splash to colonize new substrate. The specific epithet 'coronatus' likely refers to a crown-like or crownate morphological feature of the fruiting body or spore apparatus. As a saprotrophic organism, this fungus plays an important functional role in forest floor decomposition, breaking down recalcitrant leaf material alongside bacteria, invertebrates, and other fungi. Its conservation status has not been evaluated by the IUCN.
