2. Pteridophytes as ecological indicators: an overview
RESUMO As pteridófitas apresentam grande potencial como indicadores ecológicos (EIs), mas pouco explorado, mostrado apenas em trabalhos esparsos. Portanto, para analisar esse potencial, revisamos artigos publicados, sites ou livros com pteridófitas como EIs, realizando buscas em cinco bases de dados acadêmicas e no Google. Selecionamos 134 estudos, feito

3. Responses of riffle beetle assemblages to deforestation in a semi-deciduous Atlantic Forest remnant
Abstract Deforestation affects freshwater assemblages since aquatic organisms are dependent on the structure of the riparian vegetation. To investigate the responses of riffle beetles (Elmidae) to deforestation, this study assessed the structure of riffle beetle assemblages found in streams running through a large and well-preserved semi-deciduous Atlantic F

6. Development of a Multimetric Index of Ecological Integrity for streams in the urban area of Campo Grande (Mato Grosso do Sul), based on benthic macroinvertebrates / Desenvolvimento de um Índice Multimétrico de Integridade Ecológica para córregos na área urbana de Campo Grande (Mato Grosso do Sul), baseado em macroinvertebrados bentônicos
Water pollution is a growing problem, especially in the water courses that flow through urban centres, receiving residential, commercial and even industrial effluents. The small amount of control that exists is often done by means of physical, chemical and bacteriological analyses. The lack of a biological alternative may be due to the paucity of research in
