Analysis of trait–performance–fitness relationships reveals pollinator-mediated selection on orchid pollination traits
Premise: The role of pollinators in evolutionary floral divergence has spurred substantial effort into measuring pollinator-mediated phenotypic selection and its variation in space and time. For such estimates, the fitness consequences of pollination processes must be separated from other factors affecting fitness. Methods: We built a fitness function linking phenotypic traits of food-deceptive or
