Figure 4. SNP species tree of 50 individuals assigned to three groups: H. insularum from Madeira, Desertas and Bugio, H. insularum from Porto Santo and H. maderiana from Porto Santo based on 696 unlinked SNPs . The maximum clade credibility tree and congruent trees are in black. The cloudogram produced by SNAPP represents the range of different topologies: the black tree displays the first topology, representing 45.93% of the accumulative trees. Pink (covering 35.53% of trees) and green (21.54%) trees display the second and third topologies, respectively. Higher-density areas of the tree indicate greater topology agreement.
