The brazilian coastal tableland ecosystems (CT) have suffered great antropic pressure derived
from demographic growth and agricultural activities in the last decades. The CT soils are
characterized by its mechanical fragility and the presence of cohesive subsurface layers that
restrict the water flow and the roots development in the profile. These constrains impose
challenges to the establishment of sustainable agricultural in the CT landscapes.
The increasing interest in determining the consequences of the agroecosystems management
in soil quality generates the need for improve the knowledge about soil properties and its functions
(SCHOENHOLTZ et al., 2000). The invertebrate soil fauna has a very close association with the
processes that occur in the decompositon subsystem, interact with microorganisms and shows
na intense sensitivity to interferences in the ecosystem. The soil fauna abundance and
composition can reflect the soil functioning pattern. In such a way, shifts in species composition
and the relative abundance of soil invertebrates have been suggested as a good bioindicator of
changes in the ecosystem (LINDEN et al., 1994). The objective of the present work was to
characterize the edaphic fauna community that occurs in forests and different crop systems at
coastal tableland domain. We also intend to understand the agriculture impact and contribute
to establish conservation strategies. This work is part of a research project where other
environmental variables are also evaluated. The samplings areas are located at the CT
landscapes at the municipalities of Umbaúba (Sergipe state), Coruripe (Alagoas state),
Acajutiba, Nova Viçosa and Cruz das Almas (Bahia state). In each municipality, areas of native
vegetation and crops were selected to sample soil fauna using ten ?pitfall traps? per area
(MOLDENKE, 1994). The invertebrate soil fauna captured was identified at a high taxonomic
level, orders in general.
The forests located at Coruripe and Acajutiba had the highest values for ecological indices,
especially Shannon index, eveness and average groups richness, what did not happen in
Umbaúba, Cruz das Almas and Nova Viçosa where it was verified the dominance of some
groups. In these municipalities the groups Acari and Entomobryomorpha raised 70% of total
individuals number, joined or separated, what characterized these forests as having low diversity
of soil fauna community. MenosThe brazilian coastal tableland ecosystems (CT) have suffered great antropic pressure derived
