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 dogmustard

<em>Erucastrum gallicum</em>, the common dogmustard, is an annual or biennial herb in the family Brassicaceae. This species has a broad distribution across Asia, Europe, and North America, with records from Japan, twenty-four European countries, Canada, Mexico, and the United States. It typically inhabits disturbed terrestrial environments such as roadsides, waste ground, agricultural margins, and rocky or sandy soils. Common dogmustard is characterized by its deeply lobed leaves, slender branching stems, and small pale yellow four-petaled flowers arranged in elongated racemes. The plant generally grows to 20–60 centimeters in height and produces narrow silique seed pods that split open at maturity to release small brown seeds. <em>Erucastrum gallicum</em> often thrives in nutrient-poor, well-drained soils and is considered a weed in some agricultural regions. Biological traits of this species remain relatively poorly documented in detail beyond basic morphological and distributional data available in the scientific literature.
