Phylogeny and cryptic diversity of the Gammarus fossarum species complex in the Czech and Slovak Republics: first results

Popis výsledku v původním jazyce

The genus Gammarus is the most diverse of epigean freshwater amphipods in Europe and many of its once thought widespread species are actually highly diverse species complexes. G. fossarum, which comprises numerous divergent lineages especially in south-eastern Europe, is no exception. Virtually nothing is known about its diversity in former Czechoslovakia, except that G. fossarum sensu stricto (the type locality lineage) occurs in Southern Bohemia. The first results of our ongoing project that will fillthis gap are exciting. We analysed genetic variation from 13 localities along the Czech-Slovak border, and five additional ones across the Bohemian Massif, by sequencing one mitochondrial and three nuclear markers, and estimated their phylogenetic relationships in the wider context of European diversity. The examined populations belong to four different clades: G. fossarum s.s. in the west, and other three lineages at the border.
