Abstract
BackgroundVarious mechanisms such as geographic barriers and glacial episodes have been proposed as determinants of intra-specific and inter-specific differentiation of populations, and the distribution of their genetic diversity. More recently, habitat and climate differences, and corresponding adaptations have been shown to be forces influencing the phylogeographic evolution of some vertebrates. In this study, we examined the contribution of these various factors on the genetic differentiation of the bent-winged bat, Miniopterus schreibersii, in southeastern Europe and Anatolia.Results and conclusionOur results showed differentiation in mitochondrial DNA coupled with weaker nuclear differentiation. We found evidence for restriction of lineages to geographical areas for hundreds of generations. The results showed that the most likely ancestral haplotype was restricted to the same geographic area (the Balkans) for at least 6,000 years. We were able to delineate the migration routes during the population expansion process, which followed the coasts and the inland for different nested mitochondrial clades. Hence, we were able to describe a scenario showing how multiple biotic and abiotic events including glacial periods, climate and historical dispersal patterns complemented each other in causing regional and local differentiation within a species.

Summary
Various mechanisms such as geographic barriers and glacial episodes have been proposed as determinants of intra-specific and inter-specific differentiation of populations, and the distribution of their genetic diversity. Continental Asia and Australia, has elements of both faunal assemblages within its boundaries, hosting an elevated number of species and endemics [1] Mexico, as another example, being located in a transition zone between tropical central America, and temperate North (page number not for citation purposes). The light blue squares designate the most ancestral haplotype, S3, in the light blue 2nd level nested clade, 2.3. When the squares comprise more than one color, they represent haplotypes comprising purple or light blue 2nd level nested clades, other than S15 or S3, being found in the particular locality. In localities 25 and 26, in addition to the red 2nd level nested clade, 2.4, haplotypes, non-S15 purple and non-S3 light-blue haplotypes are found. The colored polygrams represent the four, second-level nested clades
