“…It seems that the proportion of open, herb-rich vegetation transitional to steppes, as it is found today in the Pontic region, was comparatively stable during the stadials and interstadials of the Weichselian/Valdai Glacial in the Black Sea region, whereas deciduous oak forests and Anatolian steppes, for example, changed more in their relative abundances 43 . It is conceivable that the vast north-south extension of the steppe and forest-steppe zone in the Pontic region of Eastern Europe allowed greater stability (with relatively easy spatial shifts) of these vegetation types during cold and warm periods (without major losses) 43,44 , while the small-scale mosaic distribution of steppe-like vegetation in the Pannonian as well as in the German (Central European) region made this more difficult 1,34,[45][46][47][48] . This would explain the higher private allelic richness in the Pontic compared to the Pannonian and German region (given similar age of populations).…”

The Euro-Siberian steppe flora consists of warm- and cold-adapted species, which may have responded differently to Pleistocene glacials and interglacials. Genotyping-by-sequencing individuals from across the distribution range of the pheasant’s eye (Adonis vernalis), we aimed to gain insight into steppe florogenesis based on the species’ evolutionary history. Although the primary area of origin of the species group comprising A. vernalis, A. villosa and A. volgensis is in Asia, our results indicate that recent populations of A. vernalis are not of Asian origin but evolved in the southern part of Europe during the Pleistocene, with Spanish populations clearly genetically distinct from the Southeastern European populations. We inferred that A. vernalis migrated eastwards from the sub-Mediterranean forest-steppes of Southeastern Europe into the continental forest-steppe zone. Eastern European populations had the highest private allelic richness, indicating long-term large population sizes in this region. As a thermophilic species, A. vernalis seems unlikely to have survived in the cold deserts of the Last Glacial Maximum in Western Siberia, so this region was likely (re)colonized postglacially. Overall, our results reinforce the importance of identifying the area of origin and the corresponding ecological requirements of steppe plants in order to understand the composition of today’s steppe flora.
