Abstract

Little attention has been paid so far to the genetic legacy of the oceanic-continental gradient across Europe. Due to this gradient steppe regions become more extensive and mesic environments become more scattered towards the East. A well suited system to study the impact of this gradient on lineage differentiation is the temperate mesophilic plant Erythronium dens-canis (Liliaceae), which is widespread in southern Europe with a distribution gap in the Pannonian Plain. Moreover, the large disjunction between E. dens-canis and its sister species E. caucasicum coincides with the Pontic steppe region. By applying range-wide sampling of E. dens-canis and limited sampling of E. caucasicum, we explored their phylogeography using the plastid regions rpl32-trnL and rps15-ycf1. Three major phylogroups were identified: a Caucasian lineage, a highly structured and narrowly distributed Transylvanian lineage, and a more homogenous and widely distributed ?non-Transylvanian? lineage. Apparently, both physiographic (mountain) and climatic (steppe) barriers have caused allopatric differentiation in European Erythronium. The Southern Carpathians constitute a latitudinal barrier and the Pannonian Plain a longitudinal barrier between the Transylvanian and ?non-Transylvanian? lineages of E. dens-canis. The eastern Carpathian Basin likely functioned as a combination of cryptic eastern (mesic) and cryptic northern refugia for E. dens-canis during glacial periods. The Eastern Carpathians and particularly the Pontic steppe regions acted as a longitudinal barrier between E. dens-canis and E. caucasicum. As steppe-dominated gaps in the distribution range of Erythronium are mirrored by genetic discontinuities along longitudes this highlights the important role of the oceanic-continental gradient throughout Europe for lineage differentiation.
