dc.abstract.enThe present study is focused on Potamogeton polygonifolius – the species considered to be endangered in Germany, the Czech Republic, Poland and Switzerland. Field studies were carried out in Lower Silesia and Lusatia in southwestern Poland in order to verify the present state of the marginal populations of P. polygonifolius, to determine the habitat preferences of the species in the study area, to compare the ecological data between marginal and central populations and finally to recognise the factors constraining the easternmost limit of the P. polygonifolius. In total, 18 populations were examined, and 11 relevés were collected. The relevés gathered were compared with 95 relevés made in northwestern Germany, and with 10 relevés collected in the German part of Lusatia. There were no significant differences between the ecology of populations of P. polygonifolius on the eastern edge of its range and those in the central part. P. polygonifolius was found growing both in natural habitats like unspoiled peat bogs, and in anthropogenic habitats such as exploited peat bogs and drainage ditches. In both types of habitats its populations were abundant and competent in terms of generative propagation. The lack of geographical barriers as well as biology and fitness of P. polygonifolius individuals from the study area suggest that marginal populations are possibly a part of a large metapopulation, covering the whole (Polish and German) area of Lusatia, however, this hypothesis was not tested in detail. The main factor shaping the easternmost limit of the general range of P. polygonifolius is most likely climate, which prevents P. polygonifolius from spreading farther eastwards.pl
