Roads and highways contribute enormously to habitat fragmentation, because they can inhibit or even block animal movement across them, which may result in the ultimate division of the populations adjacent to the roads into smaller isolated subpopulations. The isolation reduces gene flow and increases risk of extinction due to a decrease in the genetic diversity of the isolated population. The aim of the present study is to determine whether highways can cause genetic subdivision of the bank vole Myodes glareolus (Schreber, 1780) and yellow-necked mouse Apodemus flavicollis (Melchior, 1834).
