Blue mussels of the Mytilus edulis species complex from South America: The application of species delimitation models to DNA sequence variation.

Smooth-shelled blue mussels, Mytilus spp., have a worldwide antitropical distribution and are ecologically and economically important. Mussels of the Mytilus edulis species complex have been the focus of numerous taxonomic and biogeographical studies, in particular in the Northern hemisphere, but th...
