The dispersal of plants or seeds through the agency of ants with the employment of attractive seed appendages and chemicals by plants that induce the ants to transport the seeds without harming the embryo or endosperm of the plant (the tissue that surrounds the embryo inside a plant seed and provides nourishment for it).

Harvesting ants do not manage to carry all the seeds they collect back to their nests, and they do not eat all of the seeds stored in their granaries.

The result is that ants are a major and fortuitous dispersal agent for plants. They are especially effective in deserts and grasslands, but many species, not necessarily specialized harvesters, play some role even in tropical forests.
