Biochemical identification of three sympatric Apodemus species by protein electrophoresis of blood samples

The allelic pattern of seralbumine and general protein 1 of the three sympatric Apodemus species Apodemus sylvaticus, A. flavicollis, and A. alpicola, were studied using electrophoretic analysis of blood samples, This method appears to be a sensitive tool for distinguishing the three Apodemus species in the Alps, Their identification on the basis of external characteristics in the field is sometimes extremely difficult, even more so for juvenile specimens. Compared to previously described methods the electrophoretic analysis does not require killing animals and can be used on juveniles.
