Boxplot showing median ± IQR (box) and 95% CI (whiskers) of standing variation PC score (axes in Figure 1) across 12 Drosophila species, for subset of proteins exhibiting a relationship with diet breadth: (a) PC1, Nucleic acid binding proteins (n = 26); (b) PC1, Transporters (n = 12); (c) PC2, Oxidoreductases (n = 9); (d) PC2, Transferases (n = 9). Species are given in order of diet breadth: white bars, specialist; light grey bars, oligophagous; dark grey bars, generalist. Species names have been abbreviated using their first three letters.
