Seed Dispersal: Animals
The guest scientist in this two-minute radio program discusses seed dispersal in plants. He first explains why it is important for seeds to be distributed away from the mother plant. Then he contrasts wind-dispersed seeds with animal-dispersed seeds, pointing out that animals can disperse larger seeds that contain more nutrients for an emerging seedling. The program, which is available here in audio and text, is part of a Pulse of the Planet series on seed dispersal. Copyright 2005 Eisenhower Na
