摘 要:Anostraca are known by their ability for long-distance dispersal,but the existence in several species of deep,geographically structured mtDNA lineages suggests their populations are subjected to allopatric differentiation,isolation,and prevalence of local scale *** stagnalis is one of the most widespread species of Anostraca and previous studies revealed an unclear geographical pattern of mtDNA genetic ***,we analyze populations from the Iberian and Italian Peninsulas,Central Europe,and Scandinavia,with the aim to characterize the patterns of genetic diversity in a spatio-temporal framework using mtDNA and nuclear markers to test gene flow among close *** these aims we built a time-calibrated phylogeny and carried out Bayesian phylogeographic analyses using a continuous diffusion *** results indicated that *** presents a deeply structured genetic diversity,including 7 ancient lineages,some of them even predating the *** Iberian Peninsula harbors high diversity of lineages,with strong isolation and recent absence of gene flow between *** at local scale seems to be the prevailing dispersal mode of ***,which exhibits a pattern of isolation-bydistance in the Iberian *** remark the vulnerability of most of these lineages,given the limited known geographic distribution of some of them,and the high risk of losing important evolutionary potential for the species.
