Mating system divergence affects the distribution of sequence diversity within and among populations of recently diverged subspecies of Clarkia xantiana (Onagraceae).

Abstract excerpt

PREMISE OF THE STUDY: The population biology of outcrossing and self-fertilizing taxa is thought to differ because of the advantage that selfers have in colonizing unoccupied sites where mates and pollinators may be limiting (Baker's Law). This reduced tendency for outcrossers to colonize new sites, along with their greater dependence on pollinators to disperse pollen, has the potential to differently influence...
