白头海雕
白头海雕是美国国鸟,也是美国生态保护史上的成功案例,曾因滴滴涕(DDT)的广泛使用而濒临灭绝,经保护措施的实施后种群数量已显著恢复。该物种在IUCN红色名录中被评估为无危(LC),以白色头颈和尾羽与深棕色体羽形成的鲜明对比为主要识别特征。它们主要以鱼类为食,也会捕食哺乳动物和腐肉。
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.
