Holocene history of Aconitum in the Polish Western Carpathians and adjacent regions: long-distance migrations or cryptic refugia?

AbstractAconitum lasiocarpum (Rchb.) Gáyer and A. variegatum L. are forest species with overlapped geographical ranges in the Beskid Niski and Doły Jasielsko-Sanockie Depression (W. Carpathians). They form here a hybrid zone. The cytogenetic evidences based on the Giemsa C-banding in A. variegatum showed the same cytotype in the Silesian Upland and the Moravskoslezské Beskids, pointing to the role of the Moravian Gate in the migrations of plants from the Moravian glacial forest refugium. Another linked the Małopolska Upland (Ojców) with the two Carpathian regions, including the Pieniny Mts. The result points to the two hypothesis. Firstly, there existed glacial forest cryptic refugia in both regions, or the Małopolska’s population is secondary in relation to the Pieniny Mts. ISSR analysis of A. moldavicum showed relationships between one of the Małopolska’s population and the Podolian populations. The Holocene migrations of the species from the Beskid Niski to the Małopolska region were also probable. The refugial character of the Pieniny Mts. was corroborated by their close relation to the relictual populations of A. moldavicum Hacq. from the Nizke Tatry.
