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。

Ciboria batschiana is a saprotrophic cup fungus in the family Sclerotiniaceae, distributed across temperate Europe and parts of western Asia. It is one of the more frequently recorded members of the genus and typically fruits in autumn on fallen acorns and mast of oak (Quercus) species, occasionally also on beechnuts and other hard mast. The fruiting bodies are small, stalked discs with a concave to flat spore-bearing surface, ranging from pale buff to chestnut brown, and reaching up to about one centimeter across. The stalk arises from a sclerotium—a compact mass of fungal tissue within the decomposing nut—which enables the fungus to persist through unfavorable conditions. Ciboria batschiana plays a role in the decomposition of hard mast in woodland leaf litter and is categorized as Least Concern. The species is widespread but rarely abundant, and tends to be locally distributed depending on mast production years. It is associated with mature oak and beech woodland across its range. Taxonomic placement within Sclerotiniaceae has been confirmed by molecular studies. As with many small discomycetes, accurate identification requires microscopy to examine spore dimensions, paraphysis morphology, and the character of the excipular tissue. The species name honors the eighteenth-century naturalist August Johann Georg Karl Batsch.
