Biodiversité de l'avifaune aquatique des zones humides sahariennes : cas de la dépression d'Oued Righ (Algérie)
The wetlands complex of Oued Righ (Algerian NorthernSahara) includes a series of sites of undeniable importance. This eco-complex contains three very large salt pans (Chott Melghir, Chott Merouane and Chott Sidi Slimane), classified as wetlands of international importance according to the Ramsar con...
