Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

Lobo gris

El lobo gris (Canis lupus), el cánido silvestre más ampliamente distribuido, se extiende desde América del Norte a través de Eurasia en hábitats diversos que incluyen la tundra, bosques y praderas. Son animales altamente sociales que viven en manadas familiares lideradas por una pareja reproductora dominante. Como depredadores clave, los lobos regulan las poblaciones de presas y moldean profundamente la estructura del ecosistema, como demostró su reintroducción en Yellowstone. Antes muy perseguidos, las poblaciones se están recuperando en muchas regiones.
