Pollination Intensity and Paternity in Flowering Plants

​Among-plant variation in siring success plays an important role in natural selection on floral traits.  This variation is influenced by two distinct processes, which are rarely studied in unison. Pollinator-mediated interactions influence pollination success, the rate of pollen deposition onto stigmas.  Then, in the post-pollination phase, pollen competition may cause realized paternity to differ from patterns of pollen receipt.  In this paper we explore the interplay between pollination and postpollination success, and how these processes respond to ecological factors such as pollination intensity.  We note that the relative contribution of pollination and postpollination processes may not be constant, and may vary widely with pollination intensity.
