“…The first one, especially in the pasture area, and the second one more frequent in the preserved area. Dung beetles are sensitive to changes in habitat, since they have low dispersal ability, specialized diet, based mainly on mammalian excreta, and display distribution strongly influenced by vegetation cover (Halter and Arellano, 2002, Costa et al, 2009, Azevedo et al, 2011. This explains the larger amount of the insects collected in the preserved area.…”

The soil fauna plays an important function over the processes of organic matter decomposition, nutrient cycling, ground aeration and fertility. Thus, studies on the composition and structure of such communities are important, considering moreover the lack of information in different regions of Brazil and mainly related to the state of Piauí. This study aimed to evaluate the density and diversity of the soil arthropod fauna in a Cerrado area in preservation conditions and in a pasture area. Both are situated in the city of Teresina, capital of the state of Piauí. Pitfall traps were used for sampling. Five stations with four traps were placed in each area. The traps were constituted by a 500 mL plastic cup containing a preserving solution made with 70% alcohol and 40% formalin. The traps were weekly changed by occasion of the collections. Eight samples were performed in the period between March and April 2007. The results were evaluated using the following variables: number of orders, number of families, total of species and total number of individuals. Evaluation of the Diversity Index and Similarity Coefficient were also performed. As result, the variables and diversity indices were slightly higher in the preserved area. However, the similarity coefficient showed only 10% similarity between both areas.Keywords: soil, macrofauna, insects, savannah, conservation.Diversidade de artrópodes da fauna edáfica em área preservada e área manejada com pastagem no município de Teresina-Piauí-Brasil ResumoA fauna do solo exerce importante papel nos processos de decomposição da matéria orgânica, ciclos de nutrientes, aeração e fertilidade do solo. Assim, estudos sobre a composição e estrutura dessas comunidades são importantes, considerando, além disso, a escassez de informações nas diferentes regiões do Brasil e principalmente em relação ao estado do Piauí. Este estudo teve como objetivo avaliar a densidade e diversidade da fauna de artrópodes encontrados no solo em uma área de Cerrado em estado de preservação e uma área utilizada com pastagem. Ambas estão situadas no município de Teresina, capital do estado do Piauí. Armadilhas do tipo Pitfall foram utilizadas para amostragem. Cinco estações com quatro armadilhas foram colocadas em cada área. As armadilhas foram constituídas por um copo plástico (500 mL), contendo uma solução conservante feita de álcool 70% e formol 40%.

“…The diversity of the order Diptera was not only influenced by temperature but also by precipitation. Azevedo et al (2011) stated that each insect group responds differently to annual climatic variations. The authors observed that frugivorous, phytophagous and detritivorous beetles and the Gryllidae family of the order Orthoptera were more abundant in the dry season, whereas the frugivorous and scavenging Diptera predominated in the rainy season, suggesting that temperature and precipitation may influence the availability of food and shelter for these orders.…”

The phylum Arthropoda is one of the most diverse groups under the terrestrial surface comprising different classes of insects that occupy different environments. Some groups have a close relationship with the habitat they occupy, responding significantly to changes in the environment, thus indicating the level of change in the environment by their presence or absence. The present study aimed to demonstrate the importance of edaphic fauna as a bioindicator of environmental quality. This is a bibliographic review based on specialized consultation of scientific articles in the databases Google Scholar, SciELO-Scientific Electronic Library and ResearchGate. The studies found that environmental quality can be measured from the diversity and abundance of arthropods that live and perform their functions in the soil. Macrofauna influences important soil chemical and physical processes such as nutrient cycling, structuring and homogenization, and increased productivity, among others. The mesofauna, besides acting on soil properties, acts on the regulation of microbial populations, is sensitive to changes and responds promptly. The groups Acari, Collembola, Coleoptera, Hymenoptera and Araneae are indicated in several studies as potential bioindicators because they are commonly sampled in different environments. The factors identified as conditioning factors of the presence of these groups are environmental heterogeneity, type of vegetation cover and availability of litter, applied management system, seasonality, soil characteristics, and anthropic activities, among others. In short, because they respond quickly, the changes are considered to be efficient biological indicators; therefore, knowing the diversity of species and their degree of interaction with the environment allows us to analyze the effects of anthropic modifications in ecosystems.Resumo: O filo Arthropoda é um dos grupos mais diversos da superfície terrestre, compreendendo diferentes classes de insetos que ocupam diversos ambientes. Alguns grupos, entretanto, apresentam relação estreita com o habitat que ocupam, respondendo de forma significativa às modificações no ambiente, o que acaba indicando o nível de alteração desse mesmo ambiente através de sua presença ou ausência. O presente estudo objetivou demonstrar a importância da fauna edáfica como bioindicadora de qualidade ambiental. Trata-se de uma revisão bibliográfica baseada em consulta especializada de artigos científicos nos bancos de dados Google Acadêmico, SciELO-Scientific Eletronic Library e ResearchGate. Os trabalhos encontrados apontaram que a qualidade ambiental pode ser mensurada a partir da diversidade e abundância de artrópodes que vivem e desempenham suas funções no solo. A macrofauna influencia importantes processos químicos e físicos do solo como a ciclagem de nutrientes, estruturação e homogeneização, aumento da produtividade, dentre outros. Já a mesofauna, além de atuar sobre as propriedades edáficas, atua na regulação de populações microbianas e é sensível às alterações, respondendo pr...

“…According to Queiroz et al (2006), ants are excellent biological indicators, promoting soil fertility improvement and acting as efficient biological control agents. For Azevedo et al (2011), large ant presence in almost all ecosystems is justified through ant cosmopolitan habits, ease of adaptation and generalist eating habits. According to Braga et al (2010), ants are good indicators of impact on ecosystems, as they are often present in various ecosystems and are very sensitive to disturbance.…”
