Three sampling ranges denominated edge, transition and interior were delimited in each fragment. The macrofauna community was sampled at two seasons of the year (dry and wet). Monoliths were collected from soil at 10 cm depth in each range. The density and richness of the fauna, as well as the Shannon diversity index and the Pielou equitability index, were calculated. It was observed that the edge effect is expressed from the presence/absence of orders of individuals in the different fragment ranges, with no interference in the density, average wealth or number of individuals in each group. The edaphic community presents higher density and average richness in the dry period within the transition and interior range of the fragments. Keywords: fragmentation, density, richness.
