Morphological and molecular tools in identifying the Mediterranean limpets Patella caerulea, Patella aspera and Patella rustica

Allozyme electrophoresis, a partial nucleotide sequence of a mitochondrial gene for cytochrome oxidase I (COI) and discriminant analysis of shell morphometric characters were used to study the relationships among the Sicilian marine gastropods of the Patella genus. Allozyme and mtDNA markers unequivocally distinguished the species and were very useful markers in correctly classifying the different species when morphological characters overlapped each other. Several allozyme loci and many nucleotide positions were diagnostic of species. In contrast, the discriminant analysis of simple morphometric shell characters failed to adequately discriminate the species, suggesting that environmental f…
