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。

Common Ladies' Tresses

Common Ladies' Tresses (<em>Spiranthes cernua</em>) is a terrestrial orchid in the family Orchidaceae, native to North America and parts of Europe. Its range includes Belgium, Canada, and the United States, where it typically grows in grasslands, wetlands, forests, and cultivated landscapes. The species is characterized by a spiral arrangement of small white flowers along a slender stem, giving rise to the common name. It typically favors moist, open habitats including wet meadows, stream banks, bogs, and the margins of ponds, though it also occurs in drier grasslands and open woodlands. As an orchid, it depends on mycorrhizal fungi for germination and early establishment. Its conservation status has not been formally evaluated by the IUCN. Common Ladies' Tresses is considered a late-season bloomer in temperate North America and is valued as an indicator of high-quality natural habitats where it persists. Biological traits of this species remain poorly documented in the scientific literature.
