 	abstract = "ABSTRACT: Soil is the habitat for a number of living organisms that perform essential
 functions to the ecosystem. The present work aimed to determine the edaphic diversity in
 large groups under different uses and management of the soil in Cerrado Biome. The study
 was developed in the city of Mata Roma (3º 70 '80.88' 'S and 43º 18' 71.27 '' W), in the eastern
 region of the State of Maranhão, Brazil. Were installed 130 pitfall traps in five areas with
 different management (Millet, Soybean, Maize, Eucalyptus, and Pasture) and two reference
 areas with natural vegetation with different uses (anthropized Cerrado and preserved
 Cerrado). The traps remained in the field for a period of seven days, after this, the contents
 were maintained in plastic bottles and taken to the laboratory, where they were sampled and
 identified in large groups (orders and family). After identification, the biodiversity indexes
 were determined: (Shanon index, Pielou, Average and total richness and abundance). The data
 were analyzed using descriptive statistics and multivariate techniques using group
 dissimilarity. 20,995 arthropods were collected throughout the study. The highest abundance
 was found for millet (9,974 individuals), and the lowest abundance values were reported for
 soybean (222) and maize (824), respectively. The highest biodiversity index is reported for
 the soybean area (2.69), although there is less abundance, in this area, the groups are evenly
 distributed due to the homogeneous management in the study area. The main axis in the
 analysis of the main components (PCA) explained 50.9% of the correlation of the groups with
 the sampled areas. The dendrogram had demonstrated that the area of soybean and maize are
 similar and had isolated the area of millet with the most dissimilar in relation to the others.
 The use and management of the soil in the study areas determine the occurrence of soil
 arthropods in function of food availability.",
