“…It also frequently lives in association with other organisms such as Nymphaea (Marcus, 1944), gastropods (Gorni & Alves, 2006), macrophytes (Montanholi- Martins & Takeda, 2001) and also to decomposing macrophyte leaves (Martins et al 2011). It has been already detected in floodplain habitats (Ragonha & Takeda, 2014), in streams of preserved areas (Rodrigues et al 2013) and in irrigated rice fields (Stenert et al 2012).…”

“…Its occurrence has been cataloged in the States of São Paulo, Minas Gerais, Amazonas, Pará and Rio Grande do Sul. It also occurs mainly in the sediments of degraded sites (Alves & Lucca, 2000;Suriani et al 2007) and in the streams of preserved areas (Rodrigues et al 2013). In the south of the country, it has been collected in rice fields (Stenert et al 2012).…”

Abstract:Oligochaeta is one of the most common and abundant taxon in continental aquatic fauna. However, knowledge of their distribution in Brazilian ecosystems is still incomplete and fragmented. Thus, the aim of this study was to develop an inventory of aquatic oligochaetes in the Extractive Reserve of Lake Cuniã in the State of Rondônia, Brazil. Collections of data were performed during the dry (August 2015) and rainy seasons (February 2016). The sediment samples were collected near the lakeside region using the kick sampling method and a kick-net sampler (mesh size of 0.25mm). This paper provides a catalog with 12 taxon from a total of 383 specimens, distributed into two families: Naididae (95.08%) and Opistocystidae (4.92%). The Pristininae subfamily was the most significant (85.68%), followed by subfamilies: Naidinae (8.36%), Tubificinae (0.52%) and Rhyacondrilinae (0.52%). In addition, some species such as Allonais inaequalis, Aulophorus furcatus, Dero nivea, Pristina synclites, Pristina menoni and Opistocysta serrata, were recorded for the first time in the Brazilian Amazon region. Therefore, the results of this study contribute to increase knowledge on the distribution of the Oligochaeta class in Brazil, particularly in the North of the country, which is so extensive and rich in water resources, but not extensively studied.

“…que contribuíram para a regressão positiva obtida neste estudo. Estes táxons costumam apresentar elevada riqueza nos ecossistemas de água doce e, em particular, na fauna fitófila (LEARNER et al, 19 8;PINDER, 1986;RODRIGUES et al, 2013), sendo também dominantes em bancos de macrófitas aquáticas (PEARSON;MATTHEWS, 1995;TRIVINHO-STRIXINO et al, 2000;KOUAMÉ et al, 2011;MARTINS et al, 2011) onde encontram boa disponibilidade de recursos alimentares na forma de detritos orgânicos aderidos às raízes. Outras variáveis ambientais da lagoa, como, por exemplo, maior adensamento das macrófitas, proximidade das raízes do vegetal com áreas de águas abertas ou fechadas e modi cações da profundidade da lagoa, poderiam também ter in uenciado na distribuição desta macrofauna entre as raízes, contribuindo para diferentes distribuições de riqueza (SYCHRA et al, 2010).…”

Resumoacró tas aquáticas desempenham um importante papel na estruturação de comunidades dos ecossistemas de aquáticos. No presente estudo, a abundância e a riqueza da comunidade de macroinvertebrados foram comparadas através de correlação simples e da participação relativa média com o volume de raízes de Eichhornia azurea numa lagoa marginal no Pantanal ( S) no período de seca. s macroinvertebrados foram identi cados até o menor nível taxonômico possível e os volumes das raízes obtidos pelo método de deslocamento de volume. Foram identi cados 21 táxons pertencentes a 13 famílias num total de 3 1 exemplares. Chironomus sp. (Chironomidae), Slavina sp. e Dero sp. (Naididae), todos detritívoros, foram mais representativos. Houve correlação positiva entre o volume das raízes com a abundância e riqueza de macroinvertebrados. Embora a análise de variância não tenha mostrado diferenças signi cativas entre riqueza e abundância da macrofauna e o volume das raízes, observou-se uma tendência de aumento de ambas as variáveis com o aumento do volume das raízes. Assim, as raízes maiores devem ter maior disponibilidade de microhabitats usti cando a tendência observada. Os resultados obtidos indicaram que as dimensões das raízes E. azurea podem desempenhar importante papel ecológico como abrigo e local de acúmulo de alimentos para os macroinvertebrados em lagoas.

Macrophytes play an important role in the community structure of aquatic systems. In this study, we examined the macroinvertebrate communities within 20 Eichhornia azurea roots in an oxbow lake in Pantanal (MS) during dry season. Species abundance and richness were compared via linear regression, and the mean relative proportion of macroinvertebrates among root samples was determined. Macroinvertebrates were identi ed to the lowest practical taxonomic level, and root volume was measured using the volume displacement method. We identi ed 3 1 specimens, belonging to 31 families and 21 taxonomic groups. Chironomus sp.
