The role of ants and mammals in dispersal and post-dispersal seedpredation of the shrubs Grevillea (Proteaceae)

摘要

The role seed predators play in influencing the dynamics of plant populations has been little studied in Australia. The interaction of ant dispersal and seed predation on the soil seedbank in six shrubby species of Grevillea from the Sydney region of southeastern Australia was examined in selective exclusion experiments, seed array trials and placement of single seeds on the ground.
