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。

clustered burreed

Sparganium glomeratum, the clustered burreed, is an aquatic or semi-aquatic perennial herb in the family Typhaceae native to circumboreal wetland habitats across northern Europe, northern Asia, and North America. The genus Sparganium is characterized by distinctive spherical, spiky fruiting heads that give burreeds their common name. S. glomeratum is distinguished by its clustered arrangement of male and female flower heads, which are positioned closer together than in other burreed species. The plant grows in shallow water or waterlogged soils in lakes, ponds, slow streams, fens, and marshes, often forming emergent stands alongside other wetland vegetation such as sedges, rushes, and other aquatic plants. Like other aquatic macrophytes, it provides important habitat structure for aquatic invertebrates, fish, and waterfowl. The starchy rhizomes and starch-rich fruits are consumed by waterfowl and other wildlife. S. glomeratum has not been formally evaluated by the IUCN for global conservation status, but is considered secure across most of its circumpolar range in intact boreal and temperate wetlands.
