Analysis of DNAVariation and Fossil Records in Alnus glutinosa and A. incana:Changes in Distribution Ranges over Time. Recently, there is a tendency to believe, that the pattern of postglacial colonization was more complicated than the concept following the traditional paradigm of colonization from three southern peninsulas refugia in Europe. There are macrofossil records that show more northward occurrences of many temperate species in the last full-glacial (~37,000–16,000 BP). We propose to discover the postglacial migration routes and late glacial refugia of Alnus glutinosa and A. incana, which appear as cryptic species in paleobotanical studies by analysis of both pollen and macrofossil remains and population genetic structure. We are planning to investigate the population genetic structure by maternally inherited genetic marker (i.e. cpDNA) as well as by recombining genetic marker (i.e. microsatellites). Here we would like to show our first results concerning distribution of pollen and macrofossil records in Europe and microsatellites cross-amplification from various species of Betulaceae to both Alnus species.
