Abstract: 
Background: Some populations of Drosophila subobscura (Collin) inhabit geographically separate and ecologically distinct habitats of the central Balkans. Hypothesis: Some of the separate populations were genetically isolated in glacial refugia and have subsequently diverged, leading to high genetic diversity. Methods: We sampled five different D. subobscura populations. Using fragment analysis for 11 microsatellite loci, we used standard diversity parameters (expected heterozygosity, allelic richness, allele size range) to estimate population genetic structure and genetic diversity. Results: We found significant differences in the number of alleles, range of allele sizes, and expected heterozygosity between populations from ecologically distinct microhabitats. However, their geographical distance from each other did not contribute to their genetic differences. Analysis of molecular variance showed slight inter-population differentiation (F ST = 0.00996, P = 0.0215). Conclusions: Microsatellite variability parameters generally match those of other European populations. Drosophila subobscura populations of the Balkan Peninsula likely did not remain isolated in glacial refugia. Instead, our results indicate high levels of gene flow and local divergence at the molecular level. © 2011.
