Cryptic diversity and population structure at small scales: the freshwater snail Ancylus (Planorbidae, Pulmonata) in the Montseny mountain range
The freshwater limpet Ancylus fluviatilis is a known species complex. We applied COI barcoding and found two molecular clades on a small geographic scale. Their occurrence corresponds to bioclimatic conditions. We propose implementing molecular methods into diversity assessments on a regular basis.
