Resumo

The objective of this study was to identify differences in land use systems and forest management on the diversity of soil fauna and Collembola eco-morphotypes, and their relationship with physical-chemical attributes of the soil. Sampling was carried out in Native Forest (NF), Araucaria Reforestation (AR) and Eucalyptus (ER). In all, 19 taxonomic groups were identified, of which Formicidae and Collembola were the most abundant, in addition to 21 morphotypes of springtail. For TSBF, AR presented the highest abundance and NF the highest values of wealth and diversity of groups. Potassium and magnesium contents, total porosity, pore volume, penetration resistance (Rpen), organic matter, and pH were the environmental variables that contributed to explain the distribution of the soil fauna. In pitfalls traps, ER showed the greatest abundance, NF the greatest richness and AR the greatest diversity. Rpen and soil moisture contributed to explain the distribution of soil fauna. NF provided greater abundance, diversity, and richness of Collembola eco-morphotypes and biopores, macropores, clay, manganese and copper levels affected the community structure. Different forest systems affect the structure of the soil community, showing improvement in biological indicators in the Native Forest areas, Araucaria, and Eucalyptus Reforestation, under the influence of physical and chemical attributes.
