Common Knotweed

Common Knotweed (<em>Polygonum arenastrum</em>) is a prostrate annual herb in the family Polygonaceae, distributed across Asia, Europe, and North America. Its native range encompasses Taiwan in Asia, ten European countries, and Mexico and the United States in North America. The species typically colonizes highly disturbed, compacted substrates such as footpaths, roadsides, cultivated ground, and waste places, exhibiting a strong association with anthropogenic disturbance. Its wiry, branching stems and small, pale pink flowers form dense mats close to the ground, making it well adapted to trampled environments. The conservation status of this species has not been formally evaluated by the IUCN. As a cosmopolitan ruderal plant, it is broadly tolerant of environmental stress and contributes to ground cover in highly modified habitats throughout the temperate zone. Biological traits of this species remain poorly documented in the scientific literature.

Zorro rojo

El zorro rojo (Vulpes vulpes) es el carnivoro salvaje mas ampliamente distribuido de la Tierra. Ha colonizado habitats que van desde la tundra artica hasta entornos urbanos en todo el hemisferio norte y en zonas donde fue introducido en Australia. Se reconoce por su pelaje rojizo, el vientre blanco y la espesa cola. Omnivoro altamente adaptable, el zorro rojo come de todo, desde conejos y ratones de campo hasta frutos y desperdicios humanos. Se comunica con mas de 40 vocalizaciones distintas.
