Figure 3. Phylogenetic ML tree reconstructed from concatenated alignment of the nuclear genes RAG-1, BDNF, AKAP9 and NKTR.

Numbers on tree nodes indicate bootstrap values (BS) and posterior probabilities for ML BSP/MP BSP/BI BPP, respectively. Color marking of species groups corresponds to mitochondrial lineages; see Fig. 2 and Fig. S4. Thumbnails show representative species of each Phrynocephalus species group (to scale; note large size of P. mystaceus). Photographs by E. A. Dunayev and R. A. Nazarov.
