A terrestrial small mammal community from a Secondary Atlantic Forest area, located in Vicosa county (20deg. 45 minute S e 45deg. 53 minute W) was studied through one year in 1992 and through seven months in 1997, in order to observe species diversity, abundancy and composition alterations. The trapping effort was 5.760 trapnights, on the first period and 2.916 trapnights on the second period. A diversity decay was detected, from 17 to 12 species, although the dominance pattern being the same. The individual turnover was relatively low, suggesting a populational and spatial estability due to fragmentation effects. This ecological aspects and some perspectives about the small mammal studies in Atlantic Forest are discussed.
