“…The fact that this environment is a first order stream, with riparian vegetation along almost its entire course, and away from the surroundings of urban centers, contributes to its environmental quality. Monteiro et al (2008) also observed an improvement in water quality in sampling sites of Meia Ponte River basin, Goiás State, which were more distant from populated areas. In addition, the Itiz Stream presents microhabitats with riffles and that are welloxygenated, favoring the permanence of more sensitive taxa, such as Ephemeroptera, Plecoptera and Trichoptera, which increase the BMWP scores (Biasi et al 2008).…”

“…The ecological integrity of rivers and streams has become a subject of key importance for the maintenance of these resources worldwide (Monteiro et al 2008). Nevertheless, this requires knowledge about patterns of diversity and abundance of communities that comprise these ecosystems, given that many of them provide evidence of the conditions of environmental preservation of their location.…”

Benthic macroinvertebrate community structure in a stream of the north-west region of Paraná State, Brazil

This study aimed to survey the benthic macroinvertebrate fauna of a first order stream located in an agricultural area, and to assess the environmental factors involved in the spatial distribution of this community. Invertebrates were gathered in November 2007 at three sampling sites distributed along the Itiz Stream, located in Marialva municipality, Paraná State. At each site, we measured the physical and chemical variables of the water, and then took four samples, using Surber sampler. In order to evaluate the differences in density, richness, diversity and evenness, we employed an ANOVA and a DCA to summarize biotic data. The invertebrates were categorized into functional groups and the BMWP score was applied to calculate the biological integrity of the environment. The faunal composition was represented by 103 taxa distributed across five phyla, of which the highest occurrence was of arthropods, especially insects. Higher density values were observed for Chironomidae, Ephemeroptera, Coleoptera and Trichoptera. The richness, diversity and density, as well as the density of gathering-collectors, were higher in the intermediate course of the stream. The distribution pattern of the taxa was mainly influenced by lentic or lotic characteristics of the sampled sites and microhabitats, as evidenced by the DCA. The BMWP indices indicated that the three sampling sites presented scores of excellent and good water quality. In the Itiz Stream, the presence of preserved marginal vegetation and the distance from urban centers that generate pollution, combined with peculiarities of each sampling site, influenced the structure of the benthic community.

“…Apresentam características importantes como: locomoção reduzida; amostragem simples; são organismos de fácil identificação até o nível de família; respondem rapidamente a distúrbios; além de possuírem vários táxons que respondem de diferentes formas aos diversos tipos e níveis de poluição (BUSS et al, 2003). Essas características têm contribuído para o uso cada vez mais frequente desses organismos como bioindicadores em várias partes do mundo, especialmente nos Estados Unidos, Austrália, e países europeus (SURIANO et al, 2010 (MONTEIRO et. al, 2008).…”

Benthic macroinvertebrate community structure and seasonal variation in a neotropical stream in the State of Alagoas, Brazil

This paper presents a study on the macrobenthic community in the Salvia stream, a headwater stream that runs through a conserved Atlantic forest fragment in the state of Alagoas, Brazil, and identifies the environmental factors that most influence the community structure. Ten sampling sites were chosen, conducting each collection during the rainy season of 2010 and the dry season of 2011. At each site the macroinvertebrates were collected using a D net (0.250 mm mesh). Water samples were collected and taken to the laboratory to analyze Dissolved Oxygen, Conductivity, pH and Alkalinity. Water temperature, surface current speed and depth were measured at the site. Canonical Correspondence was used to analyze the effect of environmental factors on the macroinvertebrate community. All the environmental factors measured showed significant variation between seasons, showing the seasonality effects on the stream environment. Eighteen taxa were identified, with predominance of Palaemonidae (Decapoda) and Chironomidae (Diptera), respectively, during the rainy and dry season. The results showed that the macroinvertebrates were more correlated to pH, Alkalinity and Dissolved Oxygen, indicating that this ecosystem variation is mainly based on the organic matter decomposition process. Resumo: O objetivo deste estudo foi descrever a comunidade macrobentônica do riacho da Salvia, um riacho de cabeceira que atravessa um fragmento conservado de floresta remanescente de Mata Atlântica, identificando os fatores ambientais que mais influenciam a estrutura da comunidade. Dez estações de coleta foram escolhidas, onde foram realizadas coletas durante a estação chuvosa de 2010 e da estação seca de 2011. Em cada estação os macroinvertebrados foram coletados utilizando uma rede d (malha de 0,250 mm). Amostras de água foram coletadas para analisar Oxigênio Dissolvido, Condutividade, pH e Alcalinidade em laboratório. Temperatura da água, Velocidade de corrente superficial e Profundidade foram medidas em campo. Para analisar a correlação entre os fatores ambientais e a comunidade de macroinvertebrados bentônica foi utilizada a análise de Correspondência Canônica. Todos os fatores ambientais medidos mostraram variação significativa entre a estação chuvosa e seca, mostrando os efeitos da sazonalidade no ambiente do riacho. Dezoito táxons foram identificados, com Palaemonidae (Decapoda) e Chironomidae (Diptera) dominando, respectivamente, durante as estações chuvosa e seca. Os resultados mostraram que os macroinvertebrados foram mais correlacionados ao pH, Alcalinidade e Oxigênio Dissolvido, indicando que as variações neste ecossistema são baseadas principalmente nos processo de decomposição da matéria orgânica.
