Systematics and evolution of arctic‐alpine Arabis alpina (Brassicaceae) and its closest relatives in the eastern Mediterranean
• Premise of the study: The high mountains in southern Anatolia and the eastern Mediterranean are assumed to play a major role as a primary center of genetic diversity and species richness in Eurasia. We tested this hypothesis by focusing on the widespread perennial arctic‐alpine Arabis alpina and i...
