Plant sociobiology

  • The floral displays of hermaphroditic plants are often selected primarily for their effects on male function, for reasons similar to those that make males the more showy sex in animals (Queller 1983, 1985, 1997).
  • The endosperm and gametophyte nutritive tissues in plants have their own independent kin selected interests, which helps explain the evolution and function of these unusual tissues (Queller 1983, 1984, 1989).
  • Theory analogous to sex-ratio theory predicts allocation to male and female investments in hermaphrodites, and explains interspecific variation in pollen-ovule ratios (Queller 1984).
