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.

“…Unfortunately, similar to morphometrics, cytogenetics were not successful in delimiting species, given the uniformity in karyotypic characteristics of this subgenus. More recently, new molecular methods such as restriction fragment length polymorphism (Chelomina, 1996;Michaux et al, 1996Michaux et al, , 1998aMichaux et al, , 1998b, random amplified polymorphic DNA (RAPD) (Bellinvia et al, 1999), and sequencing of mitochondrial and/or nuclear genes (Chelomina, 1998;Chelomina et al, 1998;Martin et al, 2000;Serizawa et al, 2000) were used with greater success. However, most of these studies included only a limited number of Sylvaemus species and although they gave very interesting results concerning the intraspecific and interspecific phylogenetic relationships within this subgenus, many inconsistencies among the different studies remain.…”

Phylogenetic relationships among 17 extant species of Murinae, with special reference to the genus Apodemus, were investigated using sequence data from the nuclear protein-coding gene IRBP (15 species) and the two mitochondrial genes cytochrome b and 12S rRNA (17 species). The analysis of the three genes does not resolve the relationships between Mus, Apodemus, and Rattus but separates Micromys from these three genera. The analysis of the two mitochondrial regions supported an association between Apodemus and Tokudaia and indicated that these two genera are more closely related to Mus than to Rattus or Micromys. Within Apodemus, the mitochondrial data sets indicated that 8 of the 9 species analyzed can be sorted into two main groups: an Apodemus group, with A. agrarius, semotus, and peninsulae, and a Sylvaemus group, with uralensis, flavicollis, alpicola, sylvaticus, and hermonensis. The position of Apodemus mystacinus is ambiguous and might be either included in Sylvaemus or considered a distinct subgenus, Karstomys, more closely related to Sylvaemus than to Apodemus. Estimation of the divergence time for these taxa suggests a separation between 7 and 8 My ago for the three groups (mystacinus and the two subgenera Apodemus and Sylvaemus). Within each subgenus, divergence times are between 5.4 and 6 My for Apodemus and between 2.2 and 3.5 My for Sylvaemus and mystacinus. Ó
