Different distributional patterns in some small mammals in the Central Iran inferred from mtDNA markers

Quaternary climatic oscillations have influenced the species and forced them to habit in safe localities called refugees. Long time isolation has been resulted in genetic divergence that could be distinguished by phylogeographic studies. Geographic distributional patterns compared in six species using mtDNA markers in different localities mainly the Central Iran. Barrier software applied to revealing genetic barriers and probable corridors. In this case, sequences have been applied as an input data. At first, FST value for each clad was estimated and was visualized by Barrier Software. In addition, geographic coordinate data set was also imported in it. Then, Euclidean distances among each individual calculated and used to Principle component Analysis using statistical software. Comparison of geographic distributional patterns indicates incongruent models in these species that is one of features of refuge localities. It seems that each species has responded to climatic fluctuations in different ways. At the end, genetic barriers and probable corridors have investigated in the Central Iran.
