Webcontrast, animal-dispersed seeds often end up at nutrient-rich sites and may or may not be transported relatively long distances in the pro-cess (Culver and Beattie, 1978; Beattie and Culver, 1982) and thus exemplify directed dis-persal. For explosively-dispersed plants, the act of dispersal does not depend on an external agent Webexplosively dispersed species, and that clumping unrelated to dispersal distance will be higher in animal-dispersed species reflecting clumped seed deposition.
