Clipweed

pigargo-americano

A ave nacional dos Estados Unidos e símbolo do sucesso conservacionista americano, a águia-careca tem uma envergadura de até 2,4 metros e habita florestas e zonas húmidas próximas de águas abertas em toda a América do Norte. Quase extinta na década de 1960 devido ao envenenamento por DDT e à caça, recuperou de forma notável após as proibições de pesticidas e a Lei das Espécies em Perigo.

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.
