Genetic variation in an ephemeral mudflat species: The role of the soil seed bank and dispersal in river and secondary anthropogenic habitats

Popis výsledku v původním jazyce

Using microsatellite markers, we found no difference in genetic diversity levels between soil seed bank and above-ground population of Cyperus fuscus and only moderate differentiation between the two fractions collected in fishpond, fish storage ponds and river habitats. As the soil seed bank genetic diversity was tested on the basis of individuals emerged from the soil in cultivation experiment, one possible interpretation is the difference in short-term selection during germination under specific conditions (glasshouse versus field) resulting in an ecological filtering of genotypes out of the reservoir in the soil. River populations harbored significantly more genetic diversity than populations from the anthropogenic pond types. We suggest that altered levels and patterns of dispersal together with stronger selection pressures and unknown, historical processes in anthropogenic habitats are responsible for the observed reduction in genetic diversity. Dispersal is also supposed to prohibit genetic structure across Europe, where is a gradient in private allelic richness from southern Europe (high values) to northern, especially north-western, Europe (low values), which probably relates to postglacial expansion out of southern and/or eastern refugia.
