Quaternary climatic fluctuations had remained phylogeographical footprints on some organisms. Relocation of northern populations of many species to the southern parts during ice ages, followed by subsequent northward expansions from refugia during interglacial periods had been resulted in intraspecific morphological and molecular divergence. This model has been used Fat Dormouse was used as a model species for investigation about such events that happened in the Hyrcanian Refugium. By photographing of lower mandibles we would able to compare morphological differences between populations distributed along the Hyrcanian forests. We compared our results with previous molecular findings. However the role of remnant Hyrcanian forests as a refugium has been confirmed by some investigations but longterm survival and isolation of some species in this refugium from eastern and northern parts of Palearctic region trigged inter population’s evolutionary divergence. By investigation about these evolutionary diverged traits, some micro refugiums can be defined along the Hyrcanian refugia. In this study, we found some preliminary documents about the presence of eastern micro refugia based on morphological divergence of Glis glis as a model species.

The aim of present study was to investigate the genetic diversity of Garra persica populations in the Beshar and Kabgiyan rivers in Kohgiluyeh and Boyer-Ahmad province by using six microsatellite loci. In this study fulfilled on 56 Garra individuals. According to the results, the Fst value was 0.024 which indicates the low genetic differentiation between the populations. The number of alleles, observed and expected heterozygosity were, 7-25, 0.000-1.000 (the average: 0.595) and 0.767-0.946 (the average: 0.855), respectively. This indicates the allelic diversity and genetic variation of investigated populations is at favorable level. Also, analysis of molecular variance showed there is low genetic variation among populations and most of the observed variation is within the populations. According to these analyses, it seems that, Garra persica has desirable genetic diversity in investigated regions.
