Soil water and nutrient availability interactively modify pollinator‐mediated directional and correlational selection on floral display

What is it about?

Resource limitation constrains the response of Primula tibetica to among-individual variation in pollen receipt, that addition of nutrients or water leads to pollinator-mediated selection, and that effects of the two abiotic factors are nonadditive. More generally, our results highlight that variation in abiotic environmental factors can have major impact on the prevalence and strength of biotic selection.
