Águila cabeza blanca

El ave nacional de los Estados Unidos y símbolo del éxito conservacionista americano, el águila cabeza blanca tiene una envergadura de hasta 2,4 metros y habita bosques y humedales próximos a aguas abiertas en toda Norteamérica. Casi extinta en la década de 1960 por el envenenamiento con DDT y la caza, se recuperó de forma notable gracias a las prohibiciones de pesticidas y la Ley de Especies en Peligro.

Clustered yellowtops

Flaveria trinervia, commonly known as clustered yellowtops, is a fast-growing annual herb in the family Asteraceae. Native to tropical and subtropical regions, it has a remarkably wide distribution spanning Africa, Asia, Europe, and the Americas, where it thrives as a pioneer species in disturbed habitats, roadsides, agricultural margins, and waste ground. The plant typically reaches 30–90 centimeters in height, producing lance-shaped leaves arranged oppositely along branching stems. Its small yellow flower heads are clustered in dense corymbs, giving the species its common name. Flaveria trinervia is notable among plants for utilizing C4 carbon fixation, an efficient photosynthetic pathway that enables rapid growth under warm, high-light conditions with limited water. This metabolic adaptation contributes to its success as a colonizer across diverse tropical and warm-temperate environments. The species is considered Not Evaluated by the IUCN, reflecting its wide range and apparent abundance rather than any formal assessment. Seeds are dispersed by wind, facilitating its spread into new territories. Though not a major agricultural weed, it can establish in cultivated fields. The genus Flaveria, comprising around 23 species, is studied extensively by plant biologists for insights into the evolution of C4 photosynthesis from ancestral C3 pathways.
