Title: Effects of land use on ant species composition and diaspore removal in exotic grasslands in the Brazilian Pantanal (Hymenoptera : Formicidae)
Author: Uehara-Prado, M
Abstract: The influence of pasture use intensity on ant-diaspore interactions was investigated in the Brazilian Pantanal. Ants were sampled using models of myrmecochorous diaspores placed in pastures with intensive and extensive use. The two types of pasture showed low ant species richness and high species similarity, suggesting that only a few species are able to persist in this simplified environment. Diaspore removal was higher in intensive use pastures, indicating a disturbance-related change in the interaction among ants and diaspores. The factors that may account for the observed pattern are discussed.
