Blond Capuchin

The Blond Capuchin (Sapajus flavius) is a species in the genus Sapajus. It is currently classified as Endangered on the IUCN Red List. Typically found in diverse terrestrial and aquatic ecosystems.

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.
