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 asparagus fern

<em>Asparagus setaceus</em>, commonly known as Common Asparagus Fern or Lace Fern, is a climbing or sprawling perennial plant in the family Asparagaceae. Despite its common name, it is not a true fern but a flowering plant with feathery, fern-like cladodes that give it a delicate, lacy appearance. This species has not been formally evaluated by the IUCN and is widely distributed across Africa, Asia, Europe, North America, Oceania, and South America. Native to southern Africa, it has been widely introduced globally through horticulture and can become invasive in some regions. Common Asparagus Fern typically grows in a range of habitats including grasslands, wetland margins, and forest edges, often using its small hooks to climb over other vegetation. Small white or pinkish flowers are followed by dark berries that attract birds, facilitating seed dispersal. It is valued as an ornamental plant for its feathery foliage and is commonly used in floral arrangements. Biological traits of this species remain poorly documented in the scientific literature.
