Figures

Figure 1. Map of the Cape Verde Islands showing the geographical location (latitudes and longitudes) and altitudes of the islands and the origins of the new Tarentola samples included in the genetic (circles) and morphological (diamonds) analyses (Geographic Coordinate System, Datum WGS 84). Island and taxa colours match the colours used on the network analyses. No specimens were found on Sal.

Figure 2. Phylogenetic relationships of endemic Cape Verde Tarentola taxa and their relatives from the Canary Islands modified from Vasconcelos et al. (2010) based on cytochrome b and 12S rRNA genes. The tree was inferred using maximum likelihood (ML) and GTR+I+G model of sequence evolution (log likelihood = -6468.896) and was rooted using Tarentola americana. Bootstrap support values above 60% for the ML analysis are shown below nodes. Posterior probability (PP) values higher than 95% for the Bayesian analysis are represented by an asterisk (*) and are shown above nodes. Names in bold follow the new taxonomic proposal and non-bold ones the taxonomy accepted in previous recent papers (Carranza et al., 2000; Jesus et al., 2002; Vasconcelos et al., 2010). For further details see Vasconcelos et al. (2010). Characters immediately to the right of island names correspond to the 15 evolutionarily significant units (ESUs) of A, B, C, and D clades recognized in the present work and represented in split green bars. Lines of evidence (in grey): 1, mitochondrial DNA (independent cyt b parsimony networks with a connection limit of 95%; see Appendix 3); 2, nuclear DNA (absence of shared haplotypes in MC1R); 3, morphology (detection of any diagnostic morphological character or a set of a unique combination of characters). Integration approaches (in red) from the most conservative to the most inflationist: ITC stands for integration by total congruence (all lines of evidence should be congruent), IPC stands for integration by partial congruence, retained in the present study (at least two lines of evidence are necessary); IC stands for integration by cumulation (one line of evidence is sufficient). Species are represented in split red bars and subspecies in yellow.

Figure 3. Parsimony networks corresponding to the PDC, ACM4 and MC1R nDNA sequence variation in Tarentola from the Cape Verde Islands. Lines represent a mutational step, circles haplotypes and dots missing haplotypes. The size of circles is proportional to the number of haplotypes and colours to the number of individuals. The dotted circles represent the most probable ancestral haplotype. Samples from the same island are similarly coloured but with different tonalities for different taxa. For correspondences of sample and location codes see Appendix 1.

Figure 4. Discriminant analyses for males and females previously called T. darwini. The total contribution of each of the two Canonical Discriminant Functions (CDF1 and CDF2) to explain the total morphological variation is also given. See Material and methods for details.
