What is Ecological and morphological differentiation among cryptic evolutionary lineages in freshwater limpets of the nominal form‐group Ancylus fluviatilis (O.F. Müller, 1774) about?

## Abstract The phylogeny and potential mode of speciation of the river limpet __Ancylus fluviatilis__ (Basommatophora) was examined using mitochondrial DNA sequences from 16S ribosomal RNA, cytochrome __c__ oxidase subunit I (COI) and nuclear DNA from internal transcribed spacer (ITS‐1) regions from 103 populations across Europe. Four highly divergent lineages were observed within __Ancylus.__ Clade 1, representing the nominal taxon __Ancylus fluviatilis__ (O.F. Müller, 1774), is mainly found in central and northern Europe, Clade 2 is present in a single Portuguese population, Clade 3 is distributed on the Canary islands, North Africa and the eastern Mediterranean region, whereas Clade 4 inhabits the Northern Mediterranean coasts. Phylogenetic analyses revealed an overall consistent topology of nuclear and mitochondrial gene trees. Based on a molecular clock, we estimated that the basic radiation occurred in the late Pliocene. Although clades differ significantly in size independent shell shape, morphological differentiation of lineages is not feasible without genetic data. Environmental data related to climate (precipitation, temperature, etc.) showed a significant differentiatio
