To self, or not to self... A review of outcrossing and pollen-mediated gene flow in neotropical trees
Despite the typically low population densities and animal-mediated pollination of tropical forest trees, outcrossing and long-distance pollen dispersal are the norm. We reviewed the genetic literature on mating systems and pollen dispersal for neotropical trees to identify the ecological and phyloge...
