Phenotypic divergence, estimated as a quantitative score following Tobias et al. (2010), plotted against genetic divergence, estimated as Jukes-Cantor corrected <i>p</i>-distance, for 96 pairwise comparisons within 48 species.

<p>For binning purposes, thresholds of divergence are set at a phenotypic score of 7 and at 5% genetic divergence. These thresholds partition the results into 4 bins: A) Populations diverging across both genetic and phenotypic thresholds, B) high phenotypic divergence with lower genetic divergence, C) high genetic divergence with lower phenotypic divergence, and D) populations whose divergences did not surpass thresholds. Comparisons are labeled and the labels correspond to case numbers in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0159325#pone.0159325.t001" target="_blank">Table 1</a>.
