Background,Seed dispersal has long been a topic of interest to naturalists, but only rather recently has the ecology of dispersal received concerted and rigorous scientific attention (Willson 1992).

Dispersal Spectra,The fact that particular dispersal mechanisms are characteristic of certain plant communities is of great importance. However, little attempt has been made to search for broad patterns and general trends in dispersal spectra of seed plants in plant communities and geographic regions as a whole ( Willson et al.1990).

Restriction of Dispersal Due to Anchorage Mechanisms,ena differ vastly, the advantages conferred to the species by way of anchorage are similar. Myxospermic diaspores form a superficial layer of mucilage upon moistening, while trypanospermic diaspores have the ability to “drill” (bore) their diaspores into the soil.
