Frugivore Seed Dispersal
Seed dispersal is important for plants because it allows their progeny to move away from their parents in space and time. The advantages of seed dispersal may have led to the evolution of fleshy fruits, which entice animals to eat the fruits and move the plants seeds from place to place. While many fruit producing plant species would not disperse far without frugivores, they can usually germinate even if they fall to the ground directly below the parent plant.
Many types of animals are seed dispersers. Mammal and bird species represent the majority of seed dispersing species. However, frugivorous fish, tortoises, lizards, and even amphibians also disperse seeds. While frugivores and fruit-producing plant species are worldwide, there is some evidence that tropical forests have more frugivore seed dispersers than the temperate zone.

Famous quotes containing the word seed:
“On the whole, my respect for my fellow-men, except as one may outweigh a million, is not being increased these days.... Such do not know that like the seed is the fruit, and that, in the moral world, when good seed is planted, good fruit is inevitable, and does not depend on our watering and cultivating; that when you plant, or bury, a hero in his field, a crop of heroes is sure to spring up. This is a seed of such force and vitality, that it does not ask our leave to germinate.”
—Henry David Thoreau (1817–1862)
