Comparing myrmecochory in Mediterranean to tropical South American region many similarities are revealed: main location in herbaceous and preferentially anthropogenic vegetation; similar morpho-anatomical features of diaspores; many genera and families of ants as well as of plants common to both regions. In the Mediterranean region, some disseminating ants with granivorous diet are "harvesters" that store seed reserves with regard to the inproductive season (Aphaenogaster, Messor and Tetramorium). In contrast, in the tropical American region only omnivorous ants are found, related to food being available throughout the year.
