“…Based on the above, it is believed that ecological indicators such as edaphic fauna of these locations may be affecting the production response of the crops. Edaphic fauna is already known to act on organic matter decomposition, nutrient cycling, litter fragmentation and gallery opening, performing numerous ecosystem functions under different soil management systems Bender and Van Der Heijden, 2015;Choudhary et al, 2018;Pompeo et al, 2017), as well as unquestionable usefulness as indicators, usually easy to collect in the field and identify Choudhary et al, 2018;Favero et al, 2011).…”

This study aimed to evaluate the relationship of edaphic fauna under a no-tillage system with different levels of soybean productivity [High (NTH), Medium (NTM) and Low (NTL)] in the west of Santa Catarina (Brazil), identifying which chemical and physical variables most affect them, and the best indicators that can be used. Native forest (NF) areas were used as a reference. A total of 207 samples of soil fauna were collected by soil monolith and pitfall trap methods over two years of evaluation in four municipalities. Based on edaphic fauna data, Shannon-Wiener (H'), Pielou (J), Dominance (D), Margalef and Fisher Alpha (α) indices were generated, in addition to the average richness and abundance. Data from NTs were submitted to analysis of variance and compared by Tukey's test (p > 0.05). The NF was used as a reference and compared with the agriculture system by Dunnett test (p > 0.05), and regressions between soybean productivity and diversity indices. The H', Margalef, α indices, and average richness for soil fauna sampled by soil monoliths followed the productivity gradient NTH > NTM > NTL, showing a positive correlation with the increase of soybean productivity. NTH has a diversity index similar to that of NF. Soybean productivity is affected by the richness and diversity of edaphic fauna, but abundance was not sensitive in predicting treatments under no-tillage; Fisher's alpha index was more sensitive in treatment separation with soil monoliths. The environmental variables aluminum, organic matter, phosphorus, potassium and penetration resistance affect the fauna edaphic.

“…Therefore, such fauna is largely used as bioindicators (Paolleti et al, 1996, van Straalen, 1998, Parisi et al, 2005, Santoruffo et al, 2012, and some groups, such as butterflies, beetles and ants, are especially useful in environmental monitoring since they are easily sampled and identified, found all year round, and show fast response to environmental changes (Favero et al, 2011). Thus, studies on the composition, structure, behavior and ecological surveys of these communities are extremely important, considering also the lack of information in different regions of the Country and especially related to the state of Piauí.…”

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%.

“…A fauna invertebrada do solo é utilizada como indicador biológico de qualidade devido ao destaque em processos fundamentais para o biofuncionamento do solo e a sustentação de todo o bioma e, principalmente, por serem organismos sensíveis que reagem de forma rápida às mudanças promovidas por atividades antrópicas e naturais. Assim espécies, famílias ou grupos são úteis na bioindicação de mudanças ambientais, Favero et al (2011) citam como exemplos de indicadores -dentre outros -os Formicidae e os Coleoptera.…”

Resumo: O objetivo deste trabalho foi avaliar a abundância e a diversidade da fauna epígea em sistemas de manejo no bioma Caatinga. O estudo foi realizado em diferentes sistemas de cultivo: pastagem de corte irrigada (PCI), feijão-caupi (FC), milho (MI), pastagem de corte (PC) e uva irrigada (UI). Os invertebrados epígeos foram coletados com armadilhas de queda (Pitfall). Dentre os invertebrados, os grupos Formicidae, Coleoptera e Acari predominaram nos sistemas de cultivo. Tanto o número de indivíduos da fauna epígea, quanto a riqueza de grupos variaram significativamente (p<0,05) entre os sistemas de cultivo. Os sistemas UI e MI apresentaram as maiores abundâncias. As maiores riquezas de grupos foram observadas nos sistemas PC, UI e PCI. O sistema PC proporcionou maior diversidade e equitabilidade dos grupos com diferentes estratégias de sobrevivência, o que foi confirmado pela análise de componentes principais. Palavras-chave: Caatinga, bioindicadores, invertebrados do soloAbstract: The objective of this work was to evaluate the abundance and diversity of epigeous fauna in cropping systems in the Caatinga biome. The study was carried out in different cropping systems: cutting irrigated pasture (CIP), cowpea (CWP), corn (C), cutting pasture (CP) and irrigated grape (IG). Invertebrates of the epigeous fauna were collected using Pitfall traps. Among the invertebrates, the Formicidae, Coleoptera and Acari groups were dominants in cropping systems. Both the number of individuals of the epigeic fauna and the richness of groups varied significantly among cropping systems. The systems IG and C had the higher abundances. The higher groups richness were observed in the systems CP, IG and CIP. The CP system provided greater diversity and equitability of groups with different survival strategies, which was confirmed by principal component analysis.
