Structure of the genetic diversity in black poplar (Populus nigra L.) populations across European river systems: Consequences for conservation and restoration

Popis výsledku v původním jazyce

Black poplar is a keystone species of riparian ecosystems in Europe. We analysed the structure of genetic diversity of 17 populations from 11 river valleys. 1069 trees were genotyped using AFLP and microsatellites. An observed heterozygosity was 0.74. The majority of the genetic variation was present within populations. Most pairs of populations along a river were relatively similar. Overall population differentiation among rivers was considerable. The Danube and Inn populations in Austria were genetically more similar to the Vltava population in Czech Republic than the geographically more distant populations along the Tisa and Prut rivers in Ukraine. This indicates that gene flow takes place across large distances. The extent of clonal duplication washighest along regulated rivers. No duplication was found along dynamic rivers. The restoration of the natural habitat and the re-creation of the dynamics of the floodplain are the most important measures for regeneration and conservation
