The relative contributions of seed and pollen dispersal to gene flow and genetic diversity in seedlings of a tropical palm.

abstract：:Divergent host use has long been suspected to drive population differentiation and speciation in plant-feeding insects. Evaluating the contribution of divergent host use to genetic differentiation can be difficult, however, as dispersal limitation and population structure may also influence patterns of genetic variati...
