silène de france

<em>Silene gallica</em>, commonly known as the common catchfly, is a plant species that was historically distributed across Africa, Asia, Europe, the Americas, and Oceania. It typically occupied diverse terrestrial habitats, often found in disturbed ground, arable fields, roadsides, and sandy or rocky soils in temperate and Mediterranean regions. The species is classified as Extinct on the IUCN Red List, indicating that it is no longer known to exist in the wild. Common catchfly belongs to the genus <em>Silene</em> within the family Caryophyllaceae and was a slender annual herb notable for its small, often pink or white flowers and sticky stems. The loss of this species is attributed to habitat degradation, agricultural intensification, and the reduction of traditional farming practices that once maintained the open, disturbed habitats it depended upon. Biological traits such as average lifespan, plant height, and mass of this species remain poorly documented in the scientific literature. Its extinction represents a permanent loss of biodiversity across its formerly wide global range.

Canard de Laysan

Laysan Duck (Anas laysanensis) is classified as Critically Endangered (CR) on the IUCN Red List. Facing an extremely high risk of extinction in the wild due to severe population decline and habitat loss.
