Research Abstract	Although the effect of evolutionary changes in traits and genetic diversity on ecological (demographic) dynamics has received much theoretical attention, the mechanisms responsible for such ecological consequences are usually unknown. Phenotypic and genetic diversity have been suggested to increase population productivity and sustainability, and to enhance the ability of adaptive evolution. Here I investigated the ecological consequence of evolution of diversity in some polymorphic systems, including both animals and plants. I partially confirmed that mechanism and consequence of the evolution of increased genetic or phenotypic diversity, which may contribute to understand the interaction between evolutionary and ecological dynamics.
