Agents of Seed Dispersal proposes that the city is a natural ecosystem within the greater context of earth's environment. 471). This field is for validation purposes and should be left unchanged. "For example, they may fly in the wind, like a dandelion, or be moved by the water, like a coconut. A winged achene, as in maple, is called a samara.
