Abstract: Seed dispersal effectiveness is an important issue for quantifying the contribution of frugivores to plant regeneration, which shapes the persistence of plant population and maintains biodiversity of community. This paper summarized the affecting factors for dispersal effectiveness from two parts: seed dispersal quantity and seed dispersal quality. It also analyzed the effects of effective disperser assemblage on plant regeneration. Seed dispersal quantity is affected by the foraging behavior of frugivores. The animal that has a swallowing foodtreating behavior is recognized as the effective disperser. Moreover, the fruit preferred by frugivores always causes the plant to get a higher dispersal quantity. The part of seed dispersal quality could be shaped by gut passage time, seed dispersal distance and seed deposition sites of frugivores. Frugivores with large body size, high ability in habitat adaptation and migration are always recognized to be highquality dispersers because of their longer dispersal distance for plant recruitment. Moreover, the postforaging habitat selection by frugivores could determine the seed deposition sites thus affecting their dispersal quality. A highquality disperser always uses the recruitment site of plants thus deposits most seeds into the recruitment site. Different, effective dispersers show complementary roles in plant recruitment on both dispersal quantity and quality. Future researches addressing how to incorporate field monitoring of animal behavior and experiment of seed germination or to combine multiple postforaging behaviors of animals are needed to investigate seed dispersal effectiveness. Moreover, exploring seed dispersal effectiveness of the endangered and endemic plants in China should be given great consideration in the study of restoration ecology.
