Abstract

Patterns of dietary and Foraging strata utilization by the ground ant community of a Brazilian cocoa plantation were examined using sugar, meat and Flour baits on the surface as well as buried. A total of 49 ant species was recorded, including 10 species of Pheidole. Strong dominance was exercised by Solenopsis geminata at both surface and subterranean strata, and at all Food resources. More ant species attended sugar and meat baits on the surface, although each type of bait was characteristically Frequented by particular ant species. The dissimilarity matrix of the epigaeic ant Fauna was much greater than that For the hypogaeic species. At least Four guilds were identified: the fungus-growing ants, epigaeic nectivores, epigaeic carnivores, and hypogaeic Foragers. Niche breadth reduction, leading to the Formation of guilds, permits the coexistence of many species in this ground ant community From a tropical cocoa plantation.
