Quelque 17 espèces de raies et requins sur les 58 dernièrement évaluées sont désormais classées à risque d'extinction, selon l'Union internationale pour la conservation de la nature (UICN), qui publie un bilan plus détaillé et inquiétant que les précédents. "Nos résultats sont alarmants, mais pas surprenants", souligne Nicholas Dulvy, professeur à l'université Simon Fraser (Canada) et co-président du Groupe d'experts requins de l'UICN (174 spécialistes issus de 55 pays)

Australia’s reptiles face rising threats from invasive species and climate change, with 7% now threatened with extinction, The IUCN Red List update reveals after a comprehensive survey of the continent’s reptiles. The Red List now includes 975 Australian reptile species – almost all of Australia’s reptiles, the majority of them endemic to the continent. Invasive species are the main threat to the survival of over half of these threatened reptiles. A recent study found that invasive feral cats alone are estimated to kill about 600 million reptiles each year.
DocBiodiv's insight:
"The IUCN Red List now includes 93,577 species, of which 26,197 are threatened with extinction."
