Testudinidae The Moorish Tortoise (Testudo graeca) includes in its Western Mediterranean distribution fi ve parapatric subspecies that have their main range in the North of Africa (Morocco, Algeria, Tunisia and Lybia), but also occurs in some isolated locations in Europe, where populations have been identifi ed as recent. Some genetic studies have assessed the species biogeographic history in the North of Africa but these have not been focused in a regional context. The knowledge of the genetic spatial pattern of these subspecies could help us to gain a deeper understanding of the species biogeography in the north of Africa and also to identify the possible origin of European populations. In this work 7 microsatellite markers were used for 88 Algerian and Moroccan tortoises that belong to 9 different populations and a part of the cytochrome b was sequenced for some of them. These localities represent the whole range of T. g. graeca in North Africa. Our results showed that Tellian and Saharian Atlas harbour different genetic units with more levels of admixture to the East of the Tellian Atlas and in its southern side. The valley of the Moulouya River also constitutes one of the most important barriers shaping this pattern. These results are congruent with the biogeography of the species described until now. Finally, we tried to assess the origin of some south-eastern Spanish tortoises in this context, our results revealed the West of the Algerian coast as the most probable origin for these populations.
