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 Pearly Everlasting

<em>Anaphalis margaritacea</em> is a perennial herb in the family Asteraceae, native to North America and East Asia and naturalized across seventeen European countries, the United States, and Australia. The species typically inhabits open, well-drained habitats including meadows, roadsides, disturbed ground, forest clearings, and rocky slopes from lowland to montane elevations. It forms spreading colonies through rhizomes and produces clusters of papery white flower heads with persistent dry bracts that retain their appearance long after flowering, accounting for the common name "pearly everlasting." This quality makes it popular in dried flower arrangements. The woolly, silver-white stems and lance-shaped leaves are covered with dense cottony hairs that help reduce moisture loss in exposed, dry habitats. The species is dioecious, with male and female flowers borne on separate plants. Conservation status has not been formally evaluated by the IUCN, and the species is considered broadly secure given its wide distribution and adaptability. Biological traits including average lifespan, body measurements, and detailed dietary ecology remain poorly documented in standardized ecological databases for this perennial herb. <em>Anaphalis margaritacea</em> provides habitat and forage for various pollinating insects during its summer flowering period.
