In order to test the significance of geographical isolation and/ or karyological differences in microevolutionary processes at the intraspecific level we used restriction enzymes and partial sequencing to study the polymorphism of the mtDNA D-loop control region in ten Greek populations. An overall high rate of both inter- and intrapopulation polymorphism was observed. The mtDNA diversity was unevenly distributed so that most of the populations studied were very similar and closely related, and only a few of them were clearly differentiated from the others. The mtDNA analysis failed to reveal any clear variation pattern that could be correlated with karyotypic forms or geographical proximity of the populations studied. Instead, the mtDNA phylogeny gave evidence in support of the coexistence of non-polymorphic (2n = 44) and polymorphic (2n < 44) karyotypic forms within the ancestral Greek M. (T.) thomasi stock. Interestingly, only one population (Agios Stefanos) seemed to significantly diverge from all the others in both methods used, forming a well-supported paraphyletic clade. Allozymic studies have already reported similar results, corroborating the genetic peculiarity of this population. {\textcopyright} 2005 The Linnean Society of London.}, keywords = {D-loop, Karyotypic forms, Mammalia, phylogeny, RFLPs, sequencing}, author = {Thanou, E. and Fraguedakis-Tsolis, S. and Chondropoulos, B.} } @article {7937, title = {Allozyme variation in populations of the karyotypically polymorphic vole Microtus (Terricola) thomasi (Mammalia, Rodentia) from Greece}, journal = {Belgian Journal of ZoologyBelgian Journal of Zoology}, volume = {135}, number = {2}, year = {2005}, note = {Export Date: 4 September 2006Source: ScopusReferences: Corbet, G.B., (1978) The Mammals of the Palearctic Region : A Taxonomic Review, , British Museum (Natural History), Cornell University Press, New York; Fraguedakis-Tsolis, S.E., Hauffe, H.C., Searle, J.B., Genetic distinctiveness of a village population of house mice : Relevance to speciation and chromosomal evolution (1997) Proc.

The present study gives information on genetic relationships between vole populations belonging to the different karyotypic forms, based on allozyme variation. Eighteen loci were typed on cellulose acetate plates in 102 voles collected from six localities of mainland Greece, and the allelic data obtained were analysed using the biostatistical program BIOSYS-1. Populations studied show high intra- and interpopulation electrophoretic variability. A UPGMA dendrogram revealed clear separation of the "atticus" karyotype population from all others. Among the latter, two main groups exist : one including the population with the typical "thomasi" karyotype and another comprising all populations with polymorphic karyotypes.
