Ancestral area and migratory state reconstructions for Sylvia warblers. Ancestral area reconstructions above nodes are based on DIVA analysis; reconstructions below nodes are based on LaGrange analysis. Asterisks associated with individual species ranges indicate species that have broad continental distributions, but that also have distributions on Mediterranean islands; reconstructions shown above and below nodes do not reflect the inclusion of these island distributions. Alternatively, when Island is included in the distribution of those species and thus is considered as a possible ancestral area, DIVA or LaGrange reconstruct an Island ancestral area at all nodes in one major clade (indicated by asterisks to the right of nodes). Dashed branches indicate equivocal reconstructions under the most parsimonious reconstruction of migratory habit.
