13. A predictive index based on environmental filters for the bioassessment of river basins without reference areas in Atlantic Forest biome, Brazil
Resumo: Avaliações biológicas que usam a abordagem de condição de referência se baseiam na comparação entre a biota observada em locais teste e a presente em locais íntegros ou minimamente impactados. Entretanto, em muitas regiões do mundo, estes locais são escassos ou inexistentes. Neste estudo, a abordagem alternativa proposta por Chessman e Roy

14. Edaphic Macrofauna as Indicator of Edge Effect in Semi-deciduous Forest Fragments
ABSTRACT The aim of this study was to evaluate the edge effect using the macrofauna community of the soil as indicator in three fragments of Semi-deciduous Seasonal Forest in the city of Vitória da Conquista, Bahia, Brazil. Three sampling ranges denominated edge, transition and interior were delimited in each fragment. The macrofauna community was sampled

15. Soil mesofauna in consolidated land use systems: how management affects soil and litter invertebrates
ABSTRACT: Soil mesofauna consists of small invertebrates that live in the soil or litter and are sensitive to climatic conditions, management systems, plant cover and physical or chemical soil attributes. These organisms are active in the cycling of nutrients, since they fragment the organic matter hereby accelerating microbial decomposition. The aim of this

16. Termite assemblages (Blattaria, Isoptera) in two montane forest (Brejo de Altitude) areas in northeastern Brazil
Resumo: Enclaves de floresta úmida de altitude nos domínios da Caatinga, localmente conhecidos como "Brejos de Altitude", estão associados a áreas com mais de 500 m de altitude e às chuvas orográficas. O presente estudo teve como objetivo caracterizar a estrutura da taxocenose de térmitas em duas áreas de Brejo de Altitude localizadas nos municípios

17. Effects of habitat heterogeneity on epiedaphic Collembola (Arthropoda: Hexapoda) in a semiarid ecosystem in Northeast Brazil
ABSTRACT The spatial distribution of abiotic resources and environmental conditions can vary at small scales within terrestrial ecosystems, influencing the composition of soil fauna. Epiedaphic springtails (Collembola) of a semiarid Caatinga ecosystem were studied to determine if factors related to vegetation structure, such as species richness, aerial bioma

18. Spatial Variability of Soil Fauna Under Different Land Use and Managements
ABSTRACT Geostatistics allows the evaluation of the distribution pattern of data with high spatial variability in agricultural systems. This study aimed to evaluate the spatial variability of biological diversity indices of soil fauna under different land (agriculture and forest). Samples were collected in seven areas (millet, soybean, corn, eucalyptus, past

19. Simultaneous biodegradation of phenol and cyanide present in coke-oven effluent using immobilized Pseudomonas putida and Pseudomonas stutzeri
ABSTRACT Discharge of coke-oven wastewater to the environment may cause severe contamination to it and also threaten the flora and fauna, including human beings. Hence before dumping it is necessary to treat this dangerous effluent in order to minimize the damage to the environment. Conventional technologies have inherent drawbacks however, biological treatm

20. Effects of Natural Atlantic Forest Regeneration on Soil Fauna, Brazil
Abstract The stage of natural forest regeneration may influence soil fauna. This study aimed to test the hypothesis that there are differences in the structure and composition of the soil fauna communities between areas undergoing less advanced (LAS) and more advanced (MAS) stages of natural regeneration of Seasonal Semideciduous Forest at Pinheiral, RJ.

21. Epigeal Fauna and Soil Chemical Attributes in Grazing and Regeneration Areas
ABSTRACT The objective of this study was to evaluate the influence of natural pasture and spontaneous regeneration on soil chemical properties and epigeal fauna community using a secondary Atlantic Forest as reference. The study areas were located in Passa Vinte, Minas Gerais, Brazil. In each study area, pitfall traps were used to sample epigeal fauna in the

22. Application of Georadar in Areas with Different Vegetation Cover
ABSTRACT The Atlantic Forest degradation and fragmentation imposes the need for soil and vegetation assessments in order to estimate the environmental vulnerability of the remnants. The objective of this study was to evaluate the georadar applications in areas of Atlantic Forest under different forms of use in Pinheiral, State of Rio de Janeiro, Brazil, thro

23. Richness and density of aquatic benthic macroinvertebrates after exposure to fungicides and insecticides in rice paddy fields
ABSTRACT The objective of this study was to verify the richness and density of aquatic benthic macroinvertebrates after exposure to fungicides and insecticides of the rice paddy fields. In the crop seasons of 2012/13 and 2013/14, field experiments were performed, which consisted of single-dose applications of the fungicides trifloxystrobin + tebuconazole and

24. Litter Decomposition of Two Pioneer Tree Species and Associated Soil Fauna in Areas Reclaimed after Surface Coal Mining in Southern Brazil
ABSTRACT Decomposition of leaf litter from pioneer tree species and development of associated soil meso- and macrofauna are fundamental for rehabilitation processes in reclaimed coal mining areas. The aim of our study was to evaluate decomposition of Schinus terebinthifolius and Senna multijuga to answer three basic questions: (i) What type of leaf litter de
