Figure S1 in Cutting the Gordian Knot: Phylogenetic and ecological diversification of the Mesalina brevirostris species complex (Squamata, Lacertidae)
Figure S1. Results of the BI analysis of concatenated mtDNA data and GMYC species delimitation analysis. (a) MCC tree from the mtDNA analysis with posterior probabilities ≥ 0.95 shown by nodes. Sample codes correspond to those in Table S1. Branches colored in red indicate putative species identified by the GMYC species delimitation analysis. (b) Likelihood values produced by GMYC to estimate the transition between cladogenesis and intraspecific coalescence. (c) Lineagethroughtime plot based on the depicted tree that shows the transition from interspecific to intraspecific branching events (red line). The time scale in (b) and (c) is relative.
Figure S2 in Cutting the Gordian Knot: Phylogenetic and ecological diversification of the Mesalina brevirostris species complex (Squamata, Lacertidae)
Figure S2.Environmental space of the background used for developing the SDMs (grey box) and its parts occupied byMesalina bernoullii,M. brevirostris,M. saudiarabica sp. n.,M. microlepis. Values for the nine noncorrelated environmental variables are shown (for abbreviations explanation see Material and methods). The species environmental space is based on their modelled distribution. Mean values (central line), standard deviation (box) and minimum and maximum values (whiskers) are shown.
F I G U R E 3 in Cutting the Gordian Knot: Phylogenetic and ecological diversification of the Mesalina brevirostris species complex (Squamata, Lacertidae)
F I G U R E 3 Results of 100 replicates of niche identity (above diagonal) and background tests (below diagonal). Observed niche overlap (Schoener's D) is given in the upper right corner of each graph and is also indicated by red bars. The identity tests show that the niches are significantly different from models based on pooled and randomly resampled records for all species pairs except M. bernoullii—M. microlepis. Scales of the x axis of all identity tests are 0–1. Background tests show two comparisons, one of the occurrences of the species in row against the background for the species in column (black bars and p values), the other of occurrences of the species in column compared with the background for the species in row (grey bars and p values). Note that the scale of the x axes differs in the background graphs. Asterisks by p values denote significant results. Names of taxa correspond to changes proposed in this study
F I G U R E 2 in Cutting the Gordian Knot: Phylogenetic and ecological diversification of the Mesalina brevirostris species complex (Squamata, Lacertidae)
F I G U R E 2 (a) Species-tree cloudogram (grey shading) superimposed with the MCC tree (black) inferred using three mtDNA and three nDNA gene fragments. White dots mark nodes with pp support ≥.95. Mean ages are indicated for supported nodes in white rectangles by nodes together with 95% HPD (also indicated as blue bars). Higher colour densities in the cloudogram represent higher levels of certainty that given clade exists. The depicted individuals are as follows: Mesalina microlepis from Hermel, Lebanon (voucher NMP 74214/2); M. saudiarabica sp. n. from Mahazat as-Sayd, Saudi Arabia (photovoucher NMP6F 29-30, not sampled); M. bernoullii from Chosrevi, Iran (unvouchered, sample I02), M. brevirostris from the Marawah Island, UAE (unvouchered, not sampled). Specimens are not to scale. (b) Allele networks of the three nDNA gene fragments analysed. Circle sizes are proportional to the number of alleles, lines represent mutational steps. Names of taxa correspond to changes proposed in this study
F I G U R E 1 in Cutting the Gordian Knot: Phylogenetic and ecological diversification of the Mesalina brevirostris species complex (Squamata, Lacertidae)
F I G U R E 1 (a) Map of the Arabian Peninsula showing localities of material examined in this study. Large circles indicate material used for the phylogenetic analyses; smaller paler circles indicate additional records used for the SDM. Dashed line delimits the background for developing the models. Potential distributions of Mesalina bernoullii, M. brevirostris, M. microlepis and M. saudiarabica sp. n. based on the MTSS threshold are shown in corresponding colours. The green and blue striped region shows the overlap of the potential distributions of M. bernoullii and M. microlepis. (b) Plot of the environmental space of the study background and its respective parts occupied by the four species as identified by the PCA. The first two principal components and their contributions to general variation are shown. The species environmental spaces are based on their modelled distributions. Names of taxa correspond to changes proposed in this study

FIGURE 2. Bayesian phylogenetic tree of the genus Mesalina based on concatenated sequences of three mitochondrial markers (12S, 16S and cytb) and one nuclear gene (MC1R). Black dots indicate posterior probability values ≥0.95 and bootstrap values ≥70% are shown next to the nodes. Color bars correspond to the five lineages recognized within the M. guttulata complex. Sample codes are followed by locality numbers (see Figure 1 and Appendix I). Taxon names correspond to changes proposed in this study and inset pictures show specimens of the two new species described (not to scale).
