Özet
Physical barriers and major climatic oscillations in the Pleistocene are of enormous importance for the distribution and current population genetic structure of many animal taxa. Anatolia was one of the main corridors for postglacial colonization of Europe and it is characterized by rich biodiversity. In the present study, mitochondrial DNA (mtDNA) RFLPs were used to assess i) the phylogeographic relationships among 26 populations of an oak gallwasp, Andricus caputmedusae, and ii) the impact of the heterogenous topography on the geographic structure of populations. PCR was used to amplify a ca. 2540 base pair mtDNA region spanning the genes ND4, ND4L, tRNA(Thr), tRNA(Pro), ND6 and part of cytochrome b. Digestion of this region with eight restriction enzymes yielded a total of 31 haplotypes that divided sampled populations into three phylogenetic assemblages reflecting their geographic location. The average haplotype and nucleotide diversities within populations were 0.4631 and 0.101214, respectively. AMOVA analysis attributed high levels of genetic variation to variation within populations (31.26%), variation within groups (24.85%), and variation among groups (43.89%). Estimation of the age of divergence between mitochondrial lineages with reference to the geological history of Anatolia suggests that the current population structure of A. caputmedusae was shaped by both the Pleistocene climatic fluctuations and the heterogenous topography of Anatolia.
