SUMMARY:

Among the organisms that are found in the litterfall, the ants stand out for their abundance, frequency and diversity. The litterfall is a food source and shelter for many ant species. In forests, the amount and quality of the litterfall should vary temporally and spatially. These variations are connected to the phenology of the different species of trees that are found in tropical forests. The presented research had the objective to verify if the pattern of the ants assembly diversity under the treetopof diferente tree species used in reforested sites of Atlantic Forest is influenced by the collection techniques. The techniques used for ant collection were the Winkler extractor and the fall trap (pitfall). Fifty four species and twenty-three ant genres were collected in a total of forty four samples of each technique. The effect of the collection technique on the species richness was marginally significant, but there weren't statistically significant effects of the species or functional group of trees or significant effect of the interaction between trees and the collection technique. The composition of the ants assemblies in the samples was as influenced by the trees species as the collection technique, but there wasn't statistically significant interaction between the two factors. The association of collection techniques are demonstrated adequate to evaluate the richness and the ants composition of the studied site, corroborating with the literature.
