FIGURE 10 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 10. Parsimony networks corresponding to Cyt-b (A) and MC1R (B) represent reconstruction of the studied group. Numbers within parentheses represent a mutational step, black circles missing haplotypes, and colored circles haplotypes. The circle area is proportional to the number of individuals. The new nomenclature proposed in the text is used.
FIGURE 9 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 9. Maximum Likelihood (ML) tree (left) and collapsed one for the same tree (right) are given. Numbers on branches indicate the bootstrap and posterior probability (pp) values (ML/BI). Each species delimitation result is shown, and a vertical bar represents each cluster obtained from the analysis. Red circles indicate the internal nodes of each OTUs. The new nomenclature proposed in the text is used.
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).

FIGURE 3 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 3. The three-dimensional representation of MALE centroids (bidimensional of samples and centroids in Fig 2) shows the MST (Minimum Spanning Tree) superimposed on the three-dimensional representation of the position of the centroids. The three axes together explain 89.1 % of all the variability. This MST can be considered equivalent to an unrooted NJ and connects each centroid with its closest relative. See text for explanation.
FIGURE 6 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 6. The three-dimensional representation of FEMALE centroids (bidimensional of samples and centroids in Fig 5) shows the MST (Minimum Spanning Tree) superimposed on the three-dimensional representation of the position of the centroids. The three axes together explain 88.4 % of all the variability. This MST can be considered equivalent to an unrooted NJ and connects each centroid with its closest relative. See text for explanation.

FIGURE 8. A graphic display of the degree (number) of significant differences (p <0.01) among the different OTUs (MALES and FEMALES together). As can be seen, the overall representation is similar to the "old" (only morphological) taxonomy. See text for details.

FIGURE 7 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 7. UPGMA tree derived from the matrix of distances (Table 1) among FEMALE samples, as in the males one, shows three 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 = 0.94, shows that the obtained dendrogram has a very good fit (r> 0.9; Rohlf 2000).
