KEY RESULTS: A parapatric distribution of the cytotypes with a relatively wide (over 100 km in some regions) secondary contact zone was identifi ed. Mixedploidy populations, documented for the fi rst time in this species, as well as triploid individuals were found along the diploid–tetraploid borderline. Diff erent climatic requirements of the two main cytotypes were revealed, mirrored in their altitudinal separation. The tetraploids were genetically diff erentiated from both the diploids and the modeled, in silico autotetraploid genotypes, in accordance with the assumed polyploid origin and spread linked to past glaciations, and largely independent evolution in...
