Differenziazione biochimica e variabilità genetica in due popolazioni simpatriche di Apodemus sylvaticus (L., 1758) e Apodemus flavicollis (Melchior, 1834) (Rodentia, Muridae)
The taxonomic status, the possible hybridization in nature and the genetic variability of Apodemus sylvaticus and A. flavicollis has been investigated using the electrophoretic analysis of 30 enzyme loci in field populations of both species, living sympatrically in the Tolfa hills (North-West of Rome). The results obtained show: 1) A. sylvaticus and A. flavicollis are reproductively isolated and genetically well-differentiated species, easily and surely identifiable by electrophoresis; 2) in the...
