The results of the spatial evolutionary and ecological vicariance analysis (SEEVA) of E. melanogaster using mean annual temperature, annual precipitation, seasonal climatic variation and elevation coded as four quantitative section states. The total height of each histogram bar equals 100% of the observations for each clade, and the greyscale of the histograms represents the four different states. The underlined phylogeny was based on the Bayesian mitochondrial phylogeny and the species tree estimated by BP&P and *BEAST. The nodal values represent the Index of divergence (D), and asterisks indicate significant differences between sister groups using a Bonferroni criterion of P ≤ 0.05
