【 摘 要 】

The vegetal fragments size, structure and diversity have direct influence on the litter decomposition rate of decomposition, by inducing a soil biota specific community. This study was carried out to characterize the soil fauna in forest Atlantic areas with different successional stages in two different seasons (summer and winter) in Santa Maria de Jetibá, ES, Brazil. Were used two areas with different vegetation types in relation to successional stage, defi ned as: Secondary Forest "Old" (SFO) and Secondary Forest (FS). To edaphic fauna collect, were used "pit fall" traps where in each area was defi ned a plot of about 1 ha, and these were distributed randomly 10 traps. Were collected 5.009 individuals, separated into 29 taxonomic groups. The taxonomic group Díptera and functional group Holometábolos were the most representative for the SFO in the winter and summer, and FS in the winter, this behavior differs in FS in the summer there was a predominance of the Social and Formicidae groups. In the SF area was observed a greater number of individuals, total wealth and average wealth compared with the SFO. The best diversity and uniformity indexes were observed in the winter season in both areas.
