Phylogeography of Eupodes minutus (Acari : Prostigmata) on sub-Antarctic Marion Island reflects the impact of historical events
Marion Island, situated similar to 2,300 km south-east of Cape Town, South Africa, has experienced multiple volcanic and glaciation events during its history. To better understand the impact of these events on species' genetic structure, we determined the phylogeographic population structure of...
