“…It is important to recognize that leaves can protect and influence the availability of trophic resources for benthic macroinvertebrates (CALLISTO et al 2001, CRISCI-BISPO et al 2007. A benthic community similar to that of the present work was also found by CARVALHO & UIEDA (2004, CARVALHO et al (2008) and RIBEIRO & UIEDA (2005) that analyzed the benthic macroinvertebrates associated to the rocky substratum of the Ribeirão da Quinta stream. In this sense, it may be over-simplistic to assume that all invertebrates collected from litter are feeding specifically on the leaves (BOULTON & BOON 1991).…”

“…The animals were identified to the highest possible taxonomic level (PENNAK 1978, LOPRETTO & TELL 1995, MERRITT & CUMMINS 1996, FERNÁNDEZ & DOMÍNGUEZ 2001, COSTA et al 2004OLIFIERS et al 2004) and counted. In order to estimate the relative area used by each macroinvertebrate taxon when colonizing the leaves, the number of grid squares occupied by each taxon was determined using a graduate slide, according to RIBEIRO & UIEDA (2005).…”

ABSTRACT. The diet of macroinvertebrates sampled in leaf-bags incubated in a tropical stream was analyzed on a spatial scale (one forested and one deforested area) and on a temporal scale (dry and rainy seasons). The macroinvertebrates were mostly represented by detritivores specialized in fine detritus (69%), followed by generalist detritivores (10% with a diet based on fine and coarse detritus), carnivores (10%), omnivores (8%), and one detritivore genera specialized on coarse detritus (3%). The detritivores exhibited a broad spatial and temporal distribution and were represented mainly by Ephemeroptera, Trichoptera and Diptera. Phylloicus sp. (Trichoptera) consumed mostly coarse detritus (CPOM) and can be classified as the unique specialist shredder in this stream. Carnivores were represented by Anacroneuria sp.

“…At Point 2, which yielded just 24.27% of individual macroinvertebrates, Baetidae was dominant. The presence of riverside vegetation substrates at this point could potentially favor this group, which lacks morphological adaptations for rapids (Ribeiro & Uieda 2005).…”

MENEZES, M.S. A comparative analysis of biotic indices that use macroinvertebrates to assess water quality in a coastal river of Paraná state, southern Brazil. Biota Neotrop. 11(4): http://www. biotaneotropica.org.br/v11n4/en/abstract?article+bn00411042011.Abstract: Biotic indices to monitor water quality are helpful tools for evaluating the health of rivers and lakes. In Brazil water samples are mainly analyzed using physical and chemical attributes, because most biotic indices were developed in other countries and their effective application to Brazilian ecosystems requires significant research. This study compared four biotic indices commonly used to evaluate water quality via benthic macroinvertebrates in order to determine which index best reflects ecosystem health in a coastal river in Brazil's Paraná state. We also analyzed functional feeding groups. The indices studied were: 1) EPT (percent of Ephemeroptera, Plecoptera and Trichoptera); 2) BMWP' (Biological Monitoring Work Party System); 3) BMWP'-ASPT (Average Score per Taxon); and 4) HFBI (Hilsenhoff Family Biotic Index). All indices were calculated from five samples collected from April 2005 to April 2006 at two stations on the coastal do Pinto River. The river's headwaters are inside a protected area but impacts increase downriver (e.g., towns, cattle grazing, tourism). The HFBI index did the poorest job of reflecting water quality. No one index performed better than the others, and all indices yielded water quality scores that did not accurately reflect macroinvertebrate community structure because all of them had differences between ordination scores and the structure of assemblage. The functional feeding groups protocol classified the lower stretch of the river as disturbed due to human impacts, suggesting that this method is a good one to evaluate health in environments.

“…Spatial and/or temporal changes in the substrate are often observed in streams, particularly considering the physical structure, organic composition, stability and heterogeneity (Ribeiro & Uieda, 2005). As a result, we can observe a mosaic of microhabitats (Kikuchi & Uieda, 1998), which allow the establishment of Odonata species with different modes of life, such as swimmers, clingers, climbers, sprawlers, burrowers and sprawler-burrowers (Carvalho & Nessimian, 1998).…”

ABSTRACT. This study investigated the assemblages attributes (composition, abundance, richness, diversity and evenness) and the most representative genera of Odonata, Anisoptera at Água Boa and Perobão Streams, Iguatemi River basin, Brazil. Both are first order streams with similar length that are impacted by riparian forest removal and silting. Quarterly samplings were conducted from March to December 2008 in the upper, intermediate and lower stretch of each stream. The Mantel test was used to check the influence of spatial autocorrelation on the Odonata composition. Spatial variations in the composition were summarized by the Principal Coordinates Analysis (PCoA) using Mantel test residuals. The effects of spatial correlation on richness and abundance were investigated by the spatial correlogram of Moranʼs I coefficients. The most representative genera in each stream were identified by the Indicator Value Method. The spatial variations in the attributes of the assemblages were assessed using analysis of variance of null models. We collected 500 immature individuals of 23 genera and three families. Among the attributes analyzed only the composition and abundance showed significant spatial differences, with the highest mean abundance found in the Perobão Stream. Miathyria and Zenithoptera were the indicator genera of the Água Boa Stream and Erythrodiplax, Libellula, Macrothemis, Progomphus and Tramea were the indicator genera of the Perobão Stream.

Assembleia de imaturos de Odonata (Insecta, Anisoptera) em riachos sul-matogrossenses: implicações espaciais. Este trabalho investigou atributos de assembleias (composição, abundância, riqueza, diversidade e equitabilidade) e os gêneros mais representativos de Odonata, Anisoptera nos riachos Água Boa e Perobão, bacia do rio Iguatemi, MS, Brasil. Os riachos são de primeira ordem, apresentam extensão similar e são impactados pela remoção da mata ripária e assoreamento. As amostragens foram realizadas trimestralmente de março a dezembro/2008 nos trechos superior, intermediário e inferior de ambos os riachos. O teste de Mantel foi utilizado para verificar a influência da autocorrelação espacial sobre a composição de Odonata. Variações espaciais na composição foram sumarizadas através da Análise de Coordenadas Principais (PCoA) utilizando-se os resíduos do teste de Mantel. Os efeitos da correlação espacial na riqueza e abundância foram investigados através do correlograma espacial dos coeficientes do I de Moran. Para identificar os gêneros mais representativos em cada riacho foi utilizado o Método do Valor Indicador. As variações espaciais dos atributos das assembleias foram avaliadas por meio de análises de variância de modelos nulos. Foram coletados 500 indivíduos imaturos distribuídos em 23 gêneros e três famílias. Dentre os atributos analisados, apenas a composição e abundância apresentaram diferenças espaciais significativas, sendo o maior valor médio do último atributo regi...
