Abstract | Mitochondrial introgression raises questions of biogeography and of the extent of reproductive isolation and natural selection. Previous phylogenetic work on the <i>Sorex araneus</i> complex revealed apparent mitonuclear discordance in Iberian shrews, indicating past hybridisation of <i>Sorex granarius</i> and the Carlit chromosomal race of <i>S. araneus</i>, enabling introgression of the <i>S. araneus</i> mitochondrial genome into <i>S. granarius.</i> To further study this, we genetically typed 61 <i>Sorex araneus/coronatus/granarius</i> from localities in Portugal, Spain, France, and Andorra at mitochondrial, autosomal, and sex-linked loci and combined our data with the previously published sequences. Our data are consistent with earlier data indicating that <i>S. coronatus</i> and <i>S. granarius</i> are the most closely related of the three species, confirming that <i>S. granarius</i> from the Central System mountain range in Spain captured the mitochondrial genome from a population of <i>S. araneus</i>. This mitochondrial capture event can be explained by invoking a biogeographical scenario whereby <i>S. araneus</i> was in contact with <i>S. granarius</i> during the Younger Dryas in central Iberia, despite the two species currently having disjunct distributions. We discuss whether selection favoured <i>S. granarius</i> with an introgressed mitochondrial genome. Our data also suggest recent hybridisation and introgression between <i>S. coronatus</i> and <i>S. granarius</i>, as well as between <i>S. araneus</i> and <i>S. coronatus.</i> |
