Within- and Between-Population Polymorphism of the mtDNA Control Region of the Speckled Ground Squirrel (Spermophilus suslicus)

摘要

Fragmentation of distribution ranges and their reduction frequently influence the genetic structure of wild animal populations interfering with gene exchange between different parts of the distribution area, decreasing effective population size, and elevating the level of inbreeding [1]. In small isolated populations, gene drift can decrease genetic diversity, thereby limiting the adaptation to environmental changes and increasing the risk for elimination of local populations [2—4].
