Geographic sampling, clade representative and phylograms of all species in the Anolis carolinensis subgroup. Left panel: Maximum Likelihood tree consensus resulting from concatenated mitochondrial sequences. Three deep clades are coincident with the relative distribution of lineages in Cuba—western (circle), eastern (square), and central (triangle). Right panel, top: Map with the distribution of ingroup sampling localities (except some within the US), with symbols shaped and colored according to the tree. Light gray areas represent shallow waters. Discontinuous lines represent faults that are associated with paleoisland boundaries. Right panel, bottom: Sample size by species/population are also shape/colored coded (depicting males, no photos available for two species). Photo credit: Tomás M.
