Deep differentiation between and within Mediterranean glacial refugia in a flying mammal, the Myotis nattereri bat complex

Aim The role of glacial refugia in the biogeographical patterns in the Western Palaearctic region has been widely discussed, but many questions remain unre- solved. We examined the biogeography, genetic diversity, spatial distribution and evolutionary history of the Myotis nattereri bat species comp...

We examined the biogeography, genetic diversity, spatial distribution and evolutionary history of the Myotis nattereri bat species complex to investi- gate the presence of multiple refugia and the persistence of Quaternary differ- entiation between and within Mediterranean refugia in a flying mammal.
