摘　　要：Distribution area and taxonomic borders within the species complex Spermophilus erythrogenys sensu lato re­main questionable.Early evidence suggests that red-cheeked ground squirrels of Southeast Kazakhstan are re­markably different in terms of the acoustic structure of their alarm calls from the red-cheeked ground squirrels of the Kurgan region in Russia.In this study,we analyzed the differences in the acoustic structure of the alarm call and mitochondrial DNA(complete control region,1005-1006 bp and complete cytochrome b gene,1140 bp)in 3 populations of red-cheeked ground squirrels(Tara,Altyn-Emel and Balkhash),all located within ar­eas isolated by geographical barriers in Southeast Kazakhstan.We found that the alarm call variables were sim­ilar between the 3 study populations and differed by the maximum fundamental frequency(8.46±0.75 kHz)from the values(5.62±0.06 kHz)reported for the red-cheeked ground squirrels from the Kurgan region of Rus­sia.Variation in mtDNA control region was only 3%and variation in cytochrome b gene was only 2.5%.Phylo­genetic trees based on cytochrome b gene polymorphism of 44 individuals from the study area and adjacent ter­ritories indicated 3 clades with high(98-100%)bootstrap support:“intermedius,”“brevicauda”and“iliensis”).We conclude that the 3 study populations in Southeast Kazakhstan belong to the clade intermedius and suggest a taxonomical revision of the species complex Spermophilus erythrogenys sensu lato,including analyses of nu­clear DNA and alarm calls for populations of the brevicauda and iliensis clades.
