Percentage of species accumulating floral pigment types across different light environments and pollination systems. (A) Comparison of the percentage of species with the three main pigment groups between exposed (light brown) and shaded (green) light environments in California (N = 328 and 72, respectively). (B) Comparison of the percentage of species with three main pigment groups between exposed (light brown) and shaded (green) light environments in S Spain (N = 309 and 39). (C) Comparison of the percentage of species with the three main pigment groups between insect (light orange) and hummingbird (red) pollination systems in California (N = 393 and 45, respectively). (D) Comparison of the percentage of species with three main pigment groups between insect (light orange) and hummingbird (red) pollination systems in SE Brazil (N = 94 and 8). Symbols on the right show the results of permutation tests to compare the frequency of each pigment group between light environments and pollination systems (see statistical results in Supplementary Tables 1 and 2). n.s. not significant, **p < 0.01, ***p < 0.001. Images of light environments and pollination systems were generated by AI image generator DALL-E.
