Edaphic fauna and physico-chemical atributes of soil in different phytophysionomies of Cerrado

ABSTRACT The edaphic community comprises several organisms that perform ecological functions in the environment, such as litter fragmentation, nutrient cycling, and modifications of soil structure, addition to acting food chain regulators. Thus, objective this study was evaluate composition fauna physical chemical attributes different physiognomies Cerrado Parque Estadual do Mirador (PEM). carried out two formations (Sparse Typical Cerrado) PEM, where 100 pitfall traps were installed. screened identified terms orders, suborders, subfamilies, families, abundance, richness, Shannon diversity, Pielou’s equitability. A total 4,149 individuals collected from experimental plots. plot showed greater taxonomic richness (25 groups) diversity (H’ = 1.65), while Sparse presented 19 groups equal H’ 1.51. factorial exploration explained 84.43% original data 90.84% Cerrado. It is concluded differences abundance due more favorable conditions for fauna, a high content organic material vegetation cover.
