“…Likewise, Callisto et al (2002) and Kleine & Trivinho-Strixino (2005) emphasize the positive relationship between the presence of riparian vegetation with the abundance both Chironomidae as other invertebrates. This fact, summed of all other environmental characteristics of these water bodies are strengthened by habitat selection theory, which predicts that both spread and colonization of areas that provide a better fitness than species are highly nonrandom (Van Baalen & Hochberg, 2001;Morris, 2003).…”

Aim: Gradients of environmental heterogeneity perform a strong influence on the distribution of organisms and determine differences in composition, where more physically complex habitats harbor greater species richness than those simpler. We took as assumptions that differences in environmental requirements of taxa promote distinct distribution patterns which are carried through to community nestedness. Therefore, we hypothesized that more heterogeneous sites hold more nested, richer and abundant communities than those less heterogeneous ones. Methods We analyzed Chironomidae occurrence of 29 floodplain lakes, through one-year-surveys. Analyses of variance were performed to test differences among data. To test our hypothesis, we calculated correlations between the gradients of environmental heterogeneity and Chironomidae metacommunity. Results Highest values in all Chironomidae attributes were recorded in general to the floodplain lakes from Paraná System, mainly in September. Positive correlation between all Chironomidae attributes (i.e, richness, density, Biodiversity score and NODF index) both with PCA scores and variation coefficient values supported our initial hypothesis about the importance of environmental heterogeneity in metacommunity assembly. Conclusions We have demonstrated how differences in environmental heterogeneity promote the nestedness in floodplain lakes and the importance of more heterogeneous places in supporting richer and more abundant communities in species. Such results contribute to future studies on composition and richness of Chironomidae community in other kind of environments. Nested distribution suggests that, despite the existence of floodplain lakes including most of the Chironomidae richness, considering the dispersal ability of species and environmental requirements, there is a strong interaction between all environments of the area. Therefore, areas that have locations with different patterns of richness and composition are critical to maintaining the diversity of the group at the landscape level.

“…A lot of studies have emphasize the positive relationship and importance between the presence and quality of riparian vegetation both to Chironomidae and other invertebrates (Callisto et al, 2002;Kleine and Trivinho-Strixino, 2005;Callisto et al, 2007;Hepp et al, 2008;Ligeiro et al, 2013;Bruder et al, 2014). The vegetal cover also provides greater stability in terms of flow and consequently of community structure (Suriano and Fonseca-Gessner, 2004) that contribute to the habitat heterogeneity ensuring an assemblage with high richness, composed of genera and species with diversified ecological requirements and widely distributed (Amorim et al, 2004;Brown, 2007;Kon and Korukura, 2011), as found in the present study.…”

Aim:This study aimed at to evaluate the influence of habitat heterogeneity on the attributes of richness, abundance, diversity and equitability of Chironomidae assemblage and also the biological differences in faunistic composition related to each microhabitat. Methods: The sampling was performed in summer (February) and winter (August) 2010, with Surber sampler, in three headwaters streams at Atlantic Forest, in southern Brazil. Results: In the total 6,429 Chironomidae larvae were identified and classified into 96 taxa belonging to Chironominae, Tanypodinae and Ortocladiinae subfamilies. Among the microhabitats, the highest richness was observed in the deposits of litter, and the highest number of exclusive species took place in the pool regions. Conclusions: Thus, the composition and structure of the Chironomidae assemblage are directly related to the availability and heterogeneity of habitats in streams.Keywords: substrate, microhabitat, conservation unit, benthic invertebrates, richness.Resumo: Objetivo: Este trabalho teve como objetivo avaliar a influência da heterogeneidade de habitats sobre os atributos de riqueza, abundância, diversidade e equitabilidade da assembleia de Chironomidae e também as diferenças biológicas na composição faunística relacionada a cada microhabitat. Métodos: As coletas foram realizadas no verão (fevereiro) e inverno (agosto) de 2010, com um amostrador tipo Surber. Resultados: As variáveis ambientais analisadas não foram significativamente diferentes entre os riachos amostrados, porém a riqueza taxonômica de larvas de Chironomidae foi distinta entre os microhabitats. Foram identificadas 6.469 larvas de Chironomidae distribuídas em 96 táxons pertencentes às subfamílias Chironominae, Tanypodinae e Ortocladiinae. Entre os microhabitats, a maior riqueza foi observada nos depósitos de folhiços em locais de remanso, onde também foram registrados os maiores números de espécies exclusivas. Conclusões: Portanto, a composição e estrutura da assembleia de Chironomidae estão diretamente relacionadas à heterogeneidade de habitats disponíveis nos riachos.Palavras-chave: substrato, microhabitat, unidade de conservação, invertebrados bentônicos, riqueza.

“…The landscape characteristics, the soil and the vegetation, are directly related with the region climate, described as a mesothermic (Cwb, classification system of Köpper). It presents humid summer (precipitations of approximately 1,400 mm) and dry winter, with lighter temperature (Callisto et al 2002;Barbosa et al 1999;Ecodinâmica 1999). The basin proximity to the capital has contributed very much for the population growth and region development with some micro regional centers, which polluting activities are directly or indirectly linked to the Piracicaba River and tributaries.…”

“…In the case of direct launchings, it depends on the type of industry and the intensity of the human activity (Parks et al 1994;Callisto et al 2002). One of region that can serve of example of these influences is the basin of the Piracicaba River, in the State of Minas Gerais, Brazil.…”

Mercury emissions from some upstream gold mining areas and recent findings of high natural Hg levels in sediments motivated studies on the Hg cycle in the Minas Gerais state. The study presents the total mercury amount found in Geophagus brasiliensis' muscular tissue (wet weight) and sediments from Piracicaba River. Mercury was analyzed using acid digestion followed by determination of total mercury by cold vapour atomic absorption spectrophotometry. This study was also complemented with the analysis of the limnological parameters (water temperature, conductivity, total dissolved solids, suspended particles, pH, dissolved oxygen, maximum depth, photic index and total carbon). The mercury concentration in sediments samples was higher than the mercury concentration in muscular tissue of fish. The lowest Hg level measured in fish was 0.0147 microg g( - 1), while the highest was 0.101 microg g( - 1). In the sediment samples, the lowest and highest levels were 0.02 microg g( - 1) and 0.16 microg g( - 1), respectively. The Hg concentrations in fish and sediment were both under the maximum limit permitted by the World Health Organization.
