Intraspecific divergence in floral‐tube length promotes asymmetric pollen movement and reproductive isolation

What is it about?

Ecological speciation posits that divergent selection on the phenotype of an organism can also result in geneflow barriers which facilitate the speciation process. We demonstrate that flowers with different floral tube lengths place and receive pollen on different parts of a pollinator's body, and this reduces geneflow between long and short tubed flowers.
