The cranial and dental morphology of field mouse from the island of Rhodes suggests that they belong to Apodemus iconicus (=A. hermonensis) rather than to A. sylvaticus or any other Sylvaemus species. Morphological identification was supported by partial mitochondrial cytochrome b nucleotid sequences (370 bp long DNA fragment). Samples from the islands of Rhodes and Bozcaada shared 98% identity in nucleotide and 100% identity in amino acid sequences with Apodemus iconicus from Anatolia.
