Clipweed

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。

Clipweed

Clipweed (Ephedra antisyphilitica) is a leafless, photosynthetic shrub in the ancient gymnosperm family Ephedraceae, belonging to one of the oldest lineages of seed plants. Native to the arid and semi-arid regions of Texas, New Mexico, and northern Mexico, it grows on rocky slopes, desert grasslands, dry scrublands, and limestone outcrops at low to moderate elevations. The plant consists of jointed, broom-like green stems that perform photosynthesis in the absence of true leaves, which are reduced to small, papery scales at the nodes. Like other ephedras, clipweed produces alkaloids including ephedrine, historically used in traditional medicine to treat respiratory ailments and reportedly as a remedy for syphilis, hence its species epithet. Male and female strobili are borne on separate plants. The species is wind-pollinated and produces small, fleshy red seed cones. Clipweed is categorized as Least Concern given its relatively wide distribution across suitable Chihuahuan Desert habitats and its tolerance of poor, rocky soils that limit competition from other vegetation.
