A new work led by Jacek Urbaniak from Wrocław and co-authored by Michał Ronikier from our Group has been published in Preslia.

It presents a phylogeographical analysis of Hacquetia epipactis (Apiaceae), a Central European forest understorey herb, a rare component of various types of deciduous forest communities, associated with Fagus sylvatica. We attempt to discuss this case study in the context of postglacial migration of forest forming species, especially beech, and postglacial assembly or co-migration of elements of forest communities. The most plausible scenario based on cpDNA and AFLP data seems a rapid, postglacial northward expansion from a Dinaric refugium, which concurs with the published postglacial scenario for beech. However, existence of a local refugium in the northern part of the present range is not excluded based on the distribution of genetic groups, which would also be in congruence with the hypothetical last glacial history of beech. All this may indicate a possible shared migration history and role of Fagus expansion as the dominant species for the parallel establishment of Illyricoid species co-occurring in various beech-dominated communities.
