Selection of flower color phenotype by contrasting pollinator visual perception in a hybrid zone between two Calceolaria species.

Abstract excerpt

PREMISE: Colorful traits in biology are often shaped by the perception biases of animals making choices based on color. In angiosperms, flower color diversity may reflect selection by pollinators with distinct visual systems, leading to divergence within or between species. Yet, how these visual biases influence continuous flower color variation-particularly in natural hybrid swarms-remains poorly understood....
