Exotic earthworm invasion into a native forest ecosystem can cause major changes to the soil, its functioning and local plant, animal and microbial biodiversity. Little is known, however, of the extent of exotic species invasion in Brazilian forest ecosystems, and the potential effects on the soil. In the present study, the effect of anthropogenic disturbance on the presence of surface-active native and exotic earthworms was assessed in two areas of the Atlantic Rain Forest State Park in the State of São Paulo, Brazil. The earthworms were sampled from November 2004 to May 2005, using 30 pit-fall traps placed in forest areas with or without (recent) human disturbance (five traps and six transects per area). Three earthworm species were collected, belonging to two families, Megascolecidae (Amynthas sp., probably A. gracilis) and Glossoscolecidae (Pontoscolex corethrurus and Glossoscolex sp.), totaling 58 individuals overall. In the disturbed area, a significantly (?2 = 42.6, p< 0,0001) larger number of earthworms were collected, totaling 53 individuals (91% of total), all of them exotic species (51 Amynthas and two P. corethrurus). In the well-preserved forest area, only five individuals were collected, four Amynthas sp. and one native Glossoscolex sp. The invasion of the exotic species, particularly Amynthas in the disturbed area, is likely due to (among other factors) rapid movements, frequent rising to the soil surface, reproductive strategy (parthenogenesis, small, light-weight cocoons), and ecological plasticity, which permit this species to adapt to and rapidly colonize new areas, even sites relatively unfavorable to native species.
