Reductions in Grassland Species Evenness Increase Dicot Seedling Invasion and Spittle Bug Infestation

  title={Reductions in Grassland Species Evenness Increase Dicot Seedling Invasion and Spittle Bug Infestation},
  author={Brian J. Wilsey and Herbert W Polley},
Previous experiments that tested whether diverse plant communities have lower invasibility have all varied species richness. We experimentally varied evenness of four grassland species (three grasses and one forb) by planting a field experiment in Texas, and monitored the number of unplanted dicot and monocot species that invaded plots for two growing seasons. By varying evenness, we eliminated any sampling effect in our diversity treatment, because all plots contained the same plant species… CONTINUE READING
