STRUCTURE clustering outcome with K = 3 (upper panel) and K = 7 (lower panel). Admixture model applied, no LOCPRIOR used, POPFLAF = 1 for sexually breeding species (D. mixta, D. raddei, D. portschinskii, D. valentini). With K = 7, two geographic populations of D. mixta are from the Lesser and the Greater Caucasus respectively; the red cluster marks populations of D. raddei from Armenia and northern Turkey, blue cluster - D. raddei vanensis, brown cluster - D. valentini from Georgia and northeastern Turkey, yellow cluster - D. valentini from the Lake Van area
