摘要：
Post-glacial survival, potential migration routes, genetic diversity and phylogeography of the boreal moss species Rhytidium rugosum have been studied. This species is considered to be one of glacial relics of the wide but scattered Holarctic range. According to molecular data sampling from the selected European, American and Asian populations high genetic diversity of this species is present, even if this species is mostly sterile and produced sex organs extremely rarely and spread mostly asexually. Analysing the internal transcribed spacer (ITS) of the nuclear ribosomal DNA, it can be concluded that the populations of this species survived glaciations in various places in Europe and settled and re-settled present range space in various times from various refuges.
