Species conservation profiles of endemic spiders (Araneae) from Madeira and Selvagens archipelagos, Portugal
The North Atlantic archipelagos of Madeira and Selvagens present a unique biological diversity including, presently, 56 endemic spider species. Several recent projects provide valuable information on their distribution across most islands and habitats. To date, the only endemic spider assessed accor...

Extending current protected areas, restoring original habitats of threatened species and the control of invasive taxa should remain a priority for species survival.
