“…From a taxonomic point of view, the present data reinforce the opinion of Kowalski and Rzebik-Kowalska (1991), who, based on morphological characters, invalidated the taxa A. s. ifranensis Saint Girons and Van Bree, 1963 andA. s. rufescens Saint Girons andVan Bree, 1963 and considered that the wood mouse was monotypic throughout the region.…”

“…The holotype of A. s. rufescens was collected by G. Niethammer in Temmerkennit (Saint Girons and Van Bree 1963), 45 km southeast of Algiers, undoubtedly within the range of A. s. hayi. The range of the subspecies is said to cover also the high plateau of Algeria and the High Atlas region of Morocco, southeast of Marrakech (Saint Girons and Van Bree 1963). Although some "rufescens" individuals were caught in the region of Chaouen, Morocco (Saint Girons 1972), i.e., completely inside the range of A. s. hayi, the subspecific distinction was maintained only on the basis of the rufous colour and the large size of these animaIs and despite the morphological similarity to southern European wood mice (Saint Girons 1974).…”

“…Three regions were sampled, depending on the distribution of the subspecies: (i) the Mediterranean belt in Tunisia and Morocco, mostly near Tangier (locus typicus of Apodemus sylvaticus hayl'); (il') forests between Ifrane and Boulemane in the Middle Atlas Mountains, Morocco (locus typicus of A. s. ifranensis) and in Azrou, the supposed boundary between the ranges of A. s. hayi and A. s. ifranensis (Saint Girons and Van Bree 1963;Saint Girons 1972); and (iii) the Toubkal massif near Taddert in the High Atlas Mountains, where A. s. rufescens is present, according to Saint Girons and Van Bree (1963).…”

Conflicting hypotheses have been fonnulated regarding the origin of wood mouse (Apodemus sylvaticus) populations in northern Africa. ln this study, the mtDNA restriction patterns of mice (n = 28) collected in Tunisia andMorocco are compared with those of representatives from southern Europe (n = 102). The neighbour-joining tree confinns the existence of the three lineages preyiously found in the Mediterranean area: western, Tyrrhenian-BaIkan, and Sicilian. The western group is isolated from the two others, with bootstrap vaIues of 89 and 95%. Northern African patterns are included in the western group. Their variability is low, the same pattern being shared by five Tunisian and ail Moroccan animais (n = 18), caught either in the north of the country (Cap Spartel) or in the south (Marrakech).This implies that northern African wood mouse populations have a southwestern European origin and that their presence in the region is probably recent, which corresponds to both paIeontological data and the hypothesis of anthropogenic introduction.

According to fossil data, the wood mouse arrived in North Africa 7500 ya, while it was present in Europe since Early Pleistocene. Previous molecular studies suggested that its introduction in North Africa probably occurred via the Strait of Gibraltar more than 0.4 Mya ago. In this study, we widely sampled wood mice to get a better understanding of the geographic and demographic history of this species in North Africa and possibly to help resolving the discrepancy between genetic and palaeontological data. Specifically, we wanted to answer the following questions: (1) When and how did the wood mouse arrive in North Africa? and (2) What is its demographic and geographic history in North Africa since its colonization? We collected in the field 438 new individuals and used both mtDNA and six microsatellite markers to answer these questions. Our results confirm that North African wood mice have a south‐western European origin and colonized the Maghreb through the Strait of Gibraltar probably during the Mesolithic or slightly after. They first colonized the Tingitana Peninsula and then expanded throughout North Africa. Our genetic data suggest that the ancestral population size comprised numerous individuals reinforcing the idea that wood mice did not colonize Morocco accidentally through rafting of a few individuals, but via recurrent/multiple anthropogenic translocations. No spatial structuring of the genetic variability was recorded in North Africa, from Morocco to Tunisia.
