This work aims to describe and analyze the abundance, richness, diversity and interactions of macro and mesofauna as a possible bioindicator of soil quality in anthropized and non anthropized areas in the Caatinga biome located in the Sertão of Alagoas. Problematizes whether edatrophic organisms are indicators of soil quality since they participate in the food chain and energy flows in the dynamics of mineralization of organic waste by affirmatively hypothertaking affirmatively. Four areas were taken for analysis in the municipality of Santana do Ipanema, AL: Reserva Tocaia preserves (RTP), anthropized Tocaia (TA); Curral do Meio Station preserved (CP), Curral do Meio anthropized (CA). Macrofauna collection, the Tropical Soil Biology and Fertility (TSBF) method described by Anderson and Ingran, 1993, was used. The extraction of mesofauna was used the Extractor of Berlese Tullglen. All samples had their edaficos organisms quantified and identified at the order level and then submitted to the BioEsta 5.0 program to verify the diversity of Shannon and Pielou Uniformity; as well as analyzed through Generalized Linear Models (GLM), with Tukey a posteriori test. The analyses were performed in statistica 13.0 software with a significance index of 0.05; physical and chemical analysis of the soil occurred. In the analyzed environments, 1,813 individuals were found, distributed in 20 taxonomic groups.

In the analyzed environments, 1,813 individuals were found, distributed in 20 taxonomic groups. As a general result we have the area (RTP) had for macrofauna in relation to (AT) presented higher richness and lower abundance, while for mesofauna lower richness and greater abundance; the area (CP) in relation to (AC) taking into account the macrofauna was richer and more abundant and in relation to the mesofauna obtained greater abundance, but with the same richness. The most abundant macrofauna groups were haplotaxide (earthworms), hymenoptera (ants), isoptera (termites) and pulmonata (slugs and snails) and for mesophauna were Acarina and Collembolas. Can be concluded that edaficoorganisms are bioindicators of soil quality, however, further studies directed to certain faunistic groups are necessary.
