Phylogeography and conservation genetics of endangered European Margaritiferidae (Bivalvia: Unionoidea)
Margaritifera margaritifera and M. auricularia are among the most endangered freshwater mussels in the world, and the only species of the genus found in Europe. Our genetic study explores allozymic variability (27 loci) and differentiation at the mitochondrial sequence level (partial COI and 16S rRN...

Margaritifera margaritifera and M. auricularia are among the most endangered freshwater mussels in the world, and the only species of the genus found in Europe.
