The Carpathian Mountains: a biodiversity hotspot for freshwater Gammarus (Crustacea: Amphipoda)

Popis výsledku v původním jazyce

The Holarctic genus Gammarus comprises approximately 200 freshwater species exhibiting patchy distributions,weak vagility and ubiquity.Moreover,some of the apparently widespread species are actually diverse species complexes.The aim of this study was toassess the lineage diversity and estimate divergence times of two widespread species complexes in the Carpathians,G.balcanicus and G.fossarum.We sequenced the COI marker from 49 localities for G.balcanicus(118 individuals)and 46 localities for G.fossarum(94 individuals).Phylogenetic relationships were reconstructed using maximum-likelihood and two different approaches were followed for quantifying lineage diversity.Phylogenetic analysis revealed that both taxa comprise highly diverse lineages that are distinct from those of the type localities of nominal taxa.Depending on criteria used(general mixed Yule coalescent and a 16%patristic distance threshold),estimations of lineage diversity indicated at least 8(up to 45)entities within G.
