Macrofauna indicators in domestic sewage areas in landscape a brazilian dry tropical forest

Abstract

This research sought to obtain and analyze seasonally indicators of macrofauna in areas of domestic sewage in the Caatinga. The experiment was carried out at Federal University of Campina Grande, located in the city of Campina Grande - Brazil. A of 3493 individuals were analyze seasonally indicators of macrofauna in areas of domestic sewage in the Caatinga captured from the 20 traps installed at the three sampling points and at both periods (dry and wet). The taxonomy as a bioindicator indicates that there is an intense contribution of organic material coming from the effluents. There is an exuberant diversity, but with compromised soil bioturbation, so the soil formation rate is compromised and the natural pedogenic processes interrupted or altered. The soils are being altered by the domestic effluent that provides a non-labile organic material to the fauna of the soil, and this process intensified in the wet period.
