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。

Clearweed

Clearweed, Pilea pumila, is a small, annual herb in the family Urticaceae native to moist, shaded habitats across eastern North America and eastern Asia, including the eastern United States, Canada, eastern China, Japan, and Korea. The species grows in dense colonies in wet woodland, stream banks, floodplain forests, and moist disturbed ground, often forming carpets on rich, moist mineral soils in deeply shaded forest understories. The common name refers to the translucent, watery stems and smooth, bright green leaves, which give the plant an almost glassy appearance. Like its relative stinging nettle, Clearweed is a member of the nettle family but lacks the stinging hairs, making it harmless to touch. The leaves are opposite, broadly ovate with toothed margins, and the plants bear inconspicuous tiny greenish flowers that are wind-pollinated, releasing pollen in small explosive bursts. Clearweed provides food for a variety of insects and invertebrates in moist forest understory communities. The species is not considered threatened and is common across its native range, thriving in the disturbed, humid conditions found along stream margins and in second-growth forest habitats. It is occasionally weedy in gardens and greenhouses.
