Summary

The Maranhão amazon forest is the more deforested biome in Brazil. Changes in soil biodiversity had been used like reference for ecosystem functioning and to indicate recuperation of soils after a perturbation activity. The aim of this work is present the first inventory of earthworm populations living inside fallows with different aged stage and fragments of mature forest in Alcântara, Maranhão. Four types of successional stages were selected, each one with four replicates: Young Fallow (YF), Medium Fallow (MF), Old Fallow (OF) and remnant of Forest Fragment (F). Sampling was carried out by the TSBF modified method. Physical and chemicals analysis of soil samples were carried out with standards of Embrapa (1997) and the Agronomic Institute of Campinas methods. Analysis of variance and RDA were used to detect difference between treatment and select significant multiple regression. Analyses were performed with the software R (R Development Core Team 2009). A total of 16 species were observed for the county, the majority considered new species. There was observed a change in earthworm’s composition between conserved areas and early successional stages. Conserved areas presented more diversity in Urubenus spp while young fallow was dominated principally by a native new species called Brasilisia punki, follow by Righiodrilus gurupi. By the other hand, Pontoscolex corethrurus (a native invasive species) was found in all successional stages, except for matured forest. Physical and chemical factors were responsible in explain the major variance observed of the data than physiognomic gradient, with 30%, 15% and 11% respectively. This result suggest there are a complex mechanism of turnover for earthworm through natural succession involving dominance of some species at initial stages and replacing as forest is became mature.
