Introdução: À face do exponencial aumento na produção de conhecimentos científicos e da notória necessidade de empregar-se uma seleção objetiva, capaz de filtrar os estudos que detenham as categorias de análise utilizadas na investigação científica, depreende-se que os empregos de diferentes recursos de busca contribuem para a eficácia das pesquisas realizadas. Objetivo: Apresentar os principais operadores booleanos e os unitermos de busca, expondo como eles podem ser utilizados pelos pesquisadores, visando a qualidade da produção científica. Material e Método: Para tanto, realizou-se uma revisão bibliográfica. Revisão de Literatura: Destaca-se que: os operadores booleanos AND, OR e NOT ou AND NOT, são conectores utilizados para combinar os termos de interesse da pesquisa; no truncamento utiliza-se de caracteres especiais, sobretudo o asterisco (*), o cifrão ($) e o ponto de interrogação, cujo uso variam de acordo com a plataforma de pesquisa; e os unitermos de busca auxiliam no encontro de materiais condizentes com as temáticas investigadas na medida em constituem-se a partir de um vocabulário próprio e padronizado dentro do meio científico. Considerações Finais: Sugere-se a realização de novos estudos, onde diferentes metodologias de revisão sejam empregadas, visando a ampliação das questões apresentadas.
The coloured cotton crop is the best agroecological alternatives for farmers in semi-arid of Northeasthern region. Cultivation of BRS Verde cotton has been a success on productivity in this region. The practice of monoculture in cotton crop has caused loss of soil quality over the years. The organisms present in the soil are sensitive to changes of land use and management. They are excellent environmental bio indicators, representing important tool to evaluate impacts on ecosystems. In this context, the aim of this research was to evaluate the abundance and diversity of edaphic macrofauna under different management systems in the cotton crop. The design was a randomized complete block design with four replicates with five treatments in 5 collection seasons. The plots consisted of 8 lines spaced 1.0 x 0.30 m for all crops. Three PROVID traps were distributed to capture soil organisms, totally 12 samples/treatments. We identified taxonomic groups, density of organisms, ecological indexes of diversity and wealth of groups. In view of the results, we concluded that the cotton + maize consortium favoured increase of individual’s abundance and richness of faunistic groups. This cotton + maize consortium showed to be a promising alternative for better management and sustainability of the system. We also showed that soil macrofauna is a good indicator of soil quality in different cotton growing systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
