Colonization and adaptation patterns of the house mouse (Mus musculus domesticus) on the Kerguelen Archipelago
Starting from Western Europe, the house mouse (Mus musculus domesticus) has spread across the globe in historic times. However, most of the southern oceanic islands were colonized by mice only within the past 300 years. This makes them an excellent model for studying the evolutionary processes durin...

Starting from Western Europe, the house mouse (Mus musculus domesticus) has spread across the globe in historic times. However, most of the southern oceanic islands were colonized by mice only within the past 300 years. This makes them an excellent model for studying the evolutionary processes during early stages of new colonization and for understanding mechanisms of early adaptation. Twenty-four microsatellite loci and the mitochondrial D-loop sequence were typed in a total of 534 mice mainly from the Kerguelen Archipelago but also from Falkland Islands, Marion Island, Amsterdam Island, Antipodes Island, Macquarie Island, Auckland Islands, and one sample from South Georgia. Although there was heavy ship traffic for over a hundred years to the Kerguelen Archipelago, it appears that only the mice that have arrived first have colonized the main island (Grande Terre) and most of the associated small islands indeed mice shared the same D-loop haplotype as well as the same Y chromosomal haplotype.
