FIGURE 4 in Revising the taxonomy of Darevskia valentini (Boettger, 1892) and Darevskia rudis (Bedriaga, 1886) (Squamata, Lacertidae): a Morpho-Phylogenetic integrated study in a complex Anatolian scenario

FIGURE 4. UPGMA tree derived from the matrix of distances (Table 1) among MALE samples, showing three great groups: a basal one, well different, with D. bithynica (inc. ssp. tristis), and two more closer groups that include the former rudis and valentini-complexes. See the text for an explanation of the results. The tree, derived from the calculation of ultrametric distances calculated in UPGMA, reflects very well the relationships in respect to the original distanced matrix (see Table 1). Its Cophenetic Correlation Index, r = 0.95, shows that the obtained dendrogram has a very good fit (r> 0.9; Rohlf 2000).
