Estrutura da comunidade de macroinvertebrados aquáticos de um riacho de Mata Atlântica, Brasil

Composition, diversity and density of benthic macroinvertebrates were described based on samples from the four different sites of Rio Mato Grosso, Saquarema, Rio de Janeiro. Biotic and environmental data were obtained in January 2006 in microhabitats with different substrates. A total of 5.605 speci...

Sumario:Composition, diversity and density of benthic macroinvertebrates were described based on samples from the four different sites of Rio Mato Grosso, Saquarema, Rio de Janeiro. Biotic and environmental data were obtained in January 2006 in microhabitats with different substrates. A total of 5.605 specimens of the 28 insect families and two crustaceous families are sampled. The lowest values of richness, diversity, equitability and density were observed in low altitude sites. The highest diversity and density values were observed in litter substrate, while sand substrate showed lower values of these parameters.
