|Abstract: ||Describing the genetic patterns and the demographic history of expanding species is essential for providing insights into the processes linked with range dynamics. We analysed the mitochondrial diversity of
the Egyptian mongoose (Herpestes ichneumon) across the Iberian Peninsula, where the species is currently expanding northwest.
A total of 242 individuals were analysed, together with nine representatives from
the North African dispersal source. Haplotype segregation and strong differentiation between Iberian and North African populations confirmed the longterm
presence of the species in the Iberian Peninsula.
The distribution of mitochondrial diversity fitted the pattern of a historically diversified population in
southern Iberia, from which the recent dispersals into northern areas may have occurred. Higher levels of
haplotype and nucleotide diversities in the northern areas, together with the heterogeneous distribution
of pairwise population differentiations and the weak signal for isolationbydistance
suggest the existence
migrants across the Iberian Peninsula. Sudden and spatial expansion scenarios of
H. ichneumon in the Iberian Peninsula were supported by mismatch analysis and marginally supported
by neutrality tests. However, the precise time of occurrence of the detected expansion remains unclear.
Future studies should incorporate additional markers in order to further clarify the population dynamics
of the Egyptian mongoose in its Iberian range.|
