“…In contrast, Jorcin and Nogueira (2008) found no Rheotanytarsus but a high number of Djamabatista in the waterfall of the Paranapanema reservoir. A high abundance of Djamabatista larvae was also recorded by Trivinho-Strixino and Strixino (2005) who analyzed the Chironomidae community in the Ribeira River, spatially near the Paranapanema River Basin. Djamabatista larvae are good swimmers and prefer shallow water (Nessimian and Henriques-de-Oliveira 2005).…”

The usual conclusions in such studies focus on the negative aspect of the conversion of riparian forest to agricultural land (Cetra and Petrere 2007;Galbraith et al. 2008). Their presence is important for the maintenance of temperature equilibrium, as continous food supply for aquatic animals, as source of organic material and stabilization of stream banks (Marinho Filho and Reis 1989;Rodrigues 1992;Aguiar et al. 2002).Because of their widespread distribution and the sensitiveness to pollution observed for some species, chironomids are used worldwide as biological indicators of environmental quality (Bacey and Spurlock 2007;Chessman et al. 2007; Smith et al. 2007). Several projects around the world demonstrate their application as bioindicators (WRC 2001; MDFRC 2007).In Brazil, several studies have been conducted in order to analyse the influence of the surrounding land-use on the aquatic fauna (Sonoda 2005;Corbi and Trivinho-Strixino 2008). The interaction of terrestrial and aquatic systems is often analysed in small watersheds in an attempt to reduce the influence of extraneous environmental factors that, consequently, make it more difficult to detect the effects of differences in catchment landuse (Siqueira and Trivinho-Strixino 2005;Roque et al. 2008). Studies conducted on large Brazilian aquatic systems are rare in the scientific literature; as the velocity of river flow and sudden changes in the water level are some of the difficulties encountered.As stated by Vinson and Hawkins (2003), streams within similar biomes support similar number of taxa. This implies that the physical and biological environment of streams are a strong selective force on insect stream communities.The rivers studied here are similar with regard to land-use and cover, terrain slope, river channel morphology and climate. Our objective was to analyze if the Chironomidae communities from AbstractWe investigated the community of Chironomidae from three rivers belonging to the same river basin in Southern Brazil. Our objective was to analyze if the Chironomidae communities from rivers of the same basin were similar and relate this to land-use and water quality variables. Samples of insects were taken using artificial substrate baskets and left 44 days in the field for colonization during the dry season in 2002. Study reaches with the relevant land-use category present for at least 500 m along both river banks above and alongside the study reach were selected and land-use, terrain slope of the river basin and chemical and physical variables of the water were analysed. Faunal data were analyzed by number of individuals, richness of genera and community indices. Statistical analyses were performed in order to investigate the relationship between abiotic variables and the Chironomidae communities. Twenty-two genera were identified; Rheotanytarsus (Thienemann & Bause) was the most abundant in all assemblages. Some genera showed preferences in their distribution, and were observed in only one of the rivers. Land-use and slope of the terrain ...

“…The Chironominae frequently are described as the most abundant Chironomidae subfamily in the region (Suriano and Fonseca-Gessner 2004;Trivinho-Strixino and Strixino 2005;Mendes and Pinho 2009) while Orthocladiinae is the most common subfamily in lotic systems with high frequency in rapids of streams and rivers Ferrington 1984, 1996).…”

“…Though characteristic for lotic systems (Trivinho- Strixino and Strixino, 2005), Rheotanytarsus was recorded in lakes with muddy ground of the Sepotuba basin. Similarly Butakka (2000) encountered larvae of this genus in floodplain lake close to a channel connecting to the main river (Cuiabá River).…”

Benthic habitats are linked by physical processes and are essential elements in assessing of the distribution dynamics of Chironomidae dipteran insects and their role in aquatic ecosystems. This work presents results of distribution patterns of chironomids larvae in 38 sites that are abundant in the study site, inhabiting the substrate of the main river channel, rapids, tributary brook, floodplain lakes and reservoir along the Sepotuba River from its mouth at the Paraguay River to the headwater region. A total of 1,247 larvae was registered. The most abundant taxa were Polypedilum (Tripodura) sp. (25.2%), Cricotopus sp.3 (23.0%) and Tanytarsus sp. (15.0%). Fissimentum desiccatum were found only in the reservoir; Fissimentum sp.2 and Tanytarsus cf. T. obiriciae sp.2 in floodplain lakes, and Goeldichironomus sp. in the main channel. The low diversity of the sites S06 and S35 is caused by the near-exclusive presence of the species Cricotopus sp.3, alone or together with one or another taxon (Tanytarsus sp., Djalmabatista sp.3). Collectors-filterers represent 16%, collectors-gatherers 15%, predators 11% and scrapers only 1%. The predators dominated in the secondary channel (±88 ind/m 2 ), corresponding to 40% of the total of this group. Cryptochironomus sp.2 (34%) and Ablasbemyia gr. annulata (26%) were the most abundant among the predators. The differences along the river course are decisive for the formation of distinct or discontinuous communities and the limits become obvious though the interrelations between the populations in the community, as for instance, competition for food and habitats.Keywords: Chironomidae, functional trophic groups, diversity, Pantanal of Mato Grosso, floodplains.

Aim: In order to identify the factors structuring the spatial distribution of the Chironomidae community, we analyzed the effects of water and sediment characteristics, flood duration and type of phytophysiognomic unit on the taxa composition of this community. Métodos: O estudo foi realizado em 26 parcelas do Sítio de Amostragem de Longa Duração (SALD), localizado em uma área sazonalmente inundável na parte norte do Pantanal (Brasil). The study was conducted at 26 plots of the Long-Term Sampling Site, located in a seasonally flooded area in northern Pantanal (Brazil). Sediment samples were taken from each plot to analyze the Chironomidae community, organic matter and particle size; limnological parameters (depth, water temperature, dissolved oxygen, electrical conductivity and pH); besides the duration of flood. Results: We identified 432 individuals distributed into 21 Chironomidae taxa. Polypedilum and Ablabesmyia were the most frequent spatially. The multivariate multiple regression analysis showed that the community composition was significantly related to the flood duration and grain size characteristics, but not to phytophysiognomic units and limnological parameters. Plots with predominantly sandy substrate and flooded for a shorter time presented a greater occurrence of taxa. Conclusions: The gradient produced by the spatial distribution of sediment grain size and flood duration determined the distribution of Chironomidae taxa. Changes in the hydrological functioning of the Pantanal, such as those from reservoir construction in the uplands region and roads and dykes construction in the floodplain could then impact the local chironomid biodiversity.Keywords: flood duration, sediment grain size, composition of community, chironomids, Pantanal.Resumo: Objetivos: Para identificar os fatores estruturadores da distribuição espacial da comunidade de Chironomidae, analisamos os efeitos das características da água e do sedimento, da duração da inundação e do tipo de unidade fitofisionômica sobre composição de táxons desta comunidade. Métodos: O estudo foi realizado em 26 parcelas do Sítio de Amostragem de Longa Duração (SALD), localizado em uma área sazonalmente inundável na parte norte do Pantanal (Brasil). Em cada parcela foram coletadas amostras de sedimento para analisar a comunidade de Chironomidae, matéria orgânica e granulometria; parâmetros limnológicos (profundidade, temperatura da água, oxigênio dissolvido, condutividade elétrica e pH); além da duração da inundação. Resultados: Foram encontrados 432 indivíduos, distribuídos em 21 taxa de Chironomidae. Os táxons Polypedilum e Ablabesmyia foram os mais frequentes espacialmente. A análise de regressão múltipla multivariada mostrou que a composição
