Remember, insect diversity also matters. With a global reach of over 10 million monthly readers and featuring dedicated websites for science (Phys.org), Australia has a high diversity of seed-collecting ants that occur in most habitats across the continent. Phys.org is a part of Science X network. Strawberry seeds get dispersed when the fruit becomes overly ripe, falls from the plant and either it is washed downstream to another suitable growing locationor the fruit is eaten by birds (sometimes straight off of the plant) or other vectors which redistribute the seeds elsewhere.

Many birds and mammals feed on the tasty fruits, allowing the seeds to travel through the digestive system and eventually be excreted. Human beings play-no minor role in this mode of dispersal. Animals can also disperse the seeds after they pass through their digestive system. Nothing compares to the flavor of locally-grown, fresh strawberries, harvested at the peak of ripeness.
