ABSTRACT: A quantitative comparative study of ants visiting flowers in the canopies of savanna and forest in the upper
Orinoco (Venezuela) showed that flowers in the savanna are more likely to display features for avoiding ant visits
than do flowers in the forest canopy. In both, savanna and forest canopy, some flowers have special features to
attract ants, probably to reduce herbivore pressure, whereas others posses features that hinder the access of ants to
the flowers. The number of plant specimens, and of species, having flowers of the former type, is more abundant
in forest canopy; whereas the later type is predominate in the savanna.
