Abstract

Phylogenetic and taxonomic relationships in the genus Marmota were examined using inter-SINE PCR. The primers used were complementary to the consensus sequences of two short retroposons, MIR and B1-dID. The results suggest long-term genetic isolation of Nearctic and Palearctic marmots, but do not support subgeneric subdivision because of relatively low genetic differences between the marmot groups. Confirmation was received for the isolation of bobak and camtschatica, but not the caudata intrageneric species groups. Based on comparison of the mitochondrial and nuclear genome differences, the possibility of ancient hybridization between M. menzbieri and M. caudata was recognized. Species independence of M. kastschenkoi within the suggested superspecies of M. baibacina was supported.
