Habitat & Geographic Range

白头海雕

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 10 distinct biome types spanning the Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Europe (8 countries), North America (United States), and South America (Ecuador).

Common Scouring-Rush

Habitat

Typically found in moist, shaded forest floors and tropical canopies.

Range

Widely distributed across Africa (South Africa), Europe (6 countries), North America (United States), Oceania and the Pacific (Australia), and South America (Brazil). Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

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 Scouring-Rush

<em>Equisetum hyemale</em>, the common scouring rush, is a vascular plant in the family Equisetaceae, order Equisetales, representing one of the ancient lineages of spore-bearing plants with relatives dating to the Carboniferous period. This species has a broad distribution across Europe, North America, and parts of Asia, typically growing in moist, disturbed habitats such as stream banks, wet roadsides, and woodland margins. The stems of <em>Equisetum hyemale</em> are characteristically jointed, hollow, and rough-textured due to silica deposits in the outer tissue — a trait historically exploited for scouring and polishing. Unlike flowering plants, it reproduces via spores produced at terminal strobili rather than seeds. Despite its wide range, <em>Equisetum hyemale</em> is currently classified as Near Threatened by the IUCN, reflecting concern over population declines linked to wetland drainage, habitat modification, and changing hydrology across portions of its European range. Conservation measures focused on wetland and riparian habitat protection are important for the species' long-term persistence. Biological traits for this species remain poorly documented in the scientific literature, including detailed data on lifespan, growth dimensions, and dietary ecology.
