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。

Clitocybe leucodiatreta is a pale agaric fungus in the family Tricholomataceae native to temperate European forests. The species name combines 'leuco' (white) with the related species epithet 'diatreta,' suggesting morphological similarity to Clitocybe diatreta but with a distinctly paler, more whitish appearance. It inhabits deciduous and mixed woodland floors, fruiting in autumn among accumulated leaf litter where it acts as a saprotrophic decomposer of organic matter. The fruiting bodies display the characteristic Clitocybe form: a depressed to funnel-shaped cap, crowded decurrent gills, and a cylindrical stipe. Distinguishing closely related small, pale Clitocybe species requires careful examination of spore morphology, odor, taste, and ecological context, with molecular phylogenetics increasingly used to resolve taxonomic boundaries within this challenging genus. C. leucodiatreta represents part of the remarkable diversity of saprotrophic fungi in European temperate forests, ecosystems where macrofungal diversity rivals that of the plant and invertebrate communities they help sustain through decomposition.
