“…On the other hand, the low total abundance of individuals found in this study can be explained by the presence of potential predators of oligochaetes, such as odonatan and megalopteran insects. These orders were found in this steam by Rosa et al (2009) during the same period and with the same substrate types. Alves et al (2008) also found low abundance of oligochaetes (n = 259 individuals) in forest streams with cold and well oxygenated water, the beds being made up mainly by pebbles and accumulation of fine and coarse organic matter.…”

The oligochaetes are considered good indicators of ecological conditions and specific types of habitats. Among the factors that influence the distribution of these invertebrates are the water flow and the nature of the substrate. The aim of this study is to describe the composition and distribution of oligochaete species in a first-order stream in Atlantic Forest and try to identify if some species are associated with characteristics of particular types of habitats. In the dry season and in the rainy season, sand and litter samples in two riffle areas and two pool areas were collected in different parts along the stream using a hand net. The greatest observed richness and abundance occurred in sand in the pool, however the greatest estimated richness was obtained for litter in the pool. The Kruskal-Wallis analysis showed effect of the different types of habitat on the abundance and richness of oligochaetes. The Nonmetric Multidimensional Scaling (NMDS) and Multiresponse Permutation Procedure analysis (MRPP) indicated that the variation in the fauna composition had relation with different types of substrates. The indicator species analysis showed that Limnodrilus. hoffmeisteri was an indicator species in both the riffle sand and pool sand and Pristina americana was only an indicator in the pool sand. The high organic matter content in both sandy habitats probably favored the greater abundance of oligochaetes. The results showed that the substrate constitutes an important factor for the local distribution of these invertebrates in streams. The variation of the community structure among mesohabitats and the presence of indicator species of specific types of habitats in the stream demonstrate the importance of environmental heterogeneity for the oligochaetes fauna in forested streams.Keywords: indicator species, litter, sand, tropical region. Distribuição de oligoquetas em um riacho da Mata Atlântica, Sudeste do Brasil ResumoOs oligoquetos são considerados bons indicadores de condições ecológicas e de tipos específicos de habitats. Entre os principais fatores que influenciam a distribuição desses invertebrados estão o fluxo da água e a natureza do substrato. O objetivo principal desse estudo foi descrever a composição e distribuição de espécies de oligoquetas de um riacho de primeira ordem da Mata Atlântica e identificar espécies que são características de tipos específicos de habitats. Na estação seca e na estação chuvosa, amostras de areia e folhiço de duas corredeiras e dois remansos foram coletadas em diferentes manchas ao longo de um trecho do riacho usando rede de mão. A maior abundância e riqueza observada ocorreram em areia de remanso. Entretanto, a análise de rarefação mostrou que a maior riqueza estimada foi obtida em folhiço de remanso. A análise de Kruskal-Wallis mostrou o efeito dos diferentes tipos de mesohabitats sobre a abundância e riqueza de oligoquetas. A análise de Escalonamento Multidimensional não-Métrico (NMDS) e a análise de Procedimento de permutação mulitirespostas (MRPP) indicaram ...

“…This association occurs among various organisms in aquatic environments (Tokeshi, 1993). The family Chironomidae (Diptera) have been found to associate themselves phoretically with other aquatic insects, most notably Plecoptera (Dosdall and Mason, 1981;Giberson et al, 1996;Dorville´et al, 2000), Odonata (Dosdall and Parker, 1998;Vescovi Rosa et al, 2009), Ephemeroptera (Epler, 1986;Callisto and Goulart, 2000), Trichoptera (White et al, 1980;Callisto and Goulart, 2000), Megaloptera (Tracy and Hazelwood, 1983;De La Rosa, 1992;Hayashi, 1998) and Hemiptera (Roback, 1977).…”

Phoretic associations between larvae of Nanocladius (Plecopteracoluthus) asiaticus (Diptera, Chironomidae) and two species in the genus Gestroiella (Heteroptera, Naucoridae) were studied in Kanchanaburi and Ratchaburi Provinces (Western Thailand). Gestroiella siamensis was used by chironomid larvae as a host more frequently than was Gestroiella limnocoroides. Moreover, N. asiaticus larvae were associated symphoretically with nymphs of the damselfly Euphaea masoni (Odonata, Euphaeidae). This is the first report of a symphoretic association involving E. masoni. Approximately 44% of the population of naucorids harboured symphoretic chironomids, whereas only 13% of damselfly nymphs were hosts of the chironomid larvae. Most of the brachypterous male (59%) naucorids hosted chironomid larvae. The attachment site of the chironomids was frequently along the mesofemur and mesosternum of the naucorid hosts. The chironomids were attached to the ventral sides of abdominal segments of E. masoni nymphs. There was a positive correlation in body length between chironomids and naucorids (r = 0.389, P < 0.01). There are many benefits of symphoresis in the Chironomidae, such as improved feeding opportunities, increased mobility, suitable pupation sites and decreased predation risks.

“…O gênero Heteragrion foi o mais afetado pela sazonalidade. A larva desse gênero está associado a ambientes com grande concentração de vegetação marginal, além da preferência por ambientes lóticos (26). Embora a redução da lâmina d'água seja considerado como fator determinante para redução na riqueza de Zygoptera, a grande extensão do fragmento florestal, especialmente no lago da Piaba, pode ter funcionado como um importante mecanismo para manutenção permanência e aumento das espécies de Zygoptera (22).…”

Os odonatas são insetos com grande habilidade para voo durante a fase adulta, habitando locais com presença de água como lagos e rios ou mesmo pequenas poças d’água. Durante a fase larval, esses organismos habitam o ambiente aquático, compondo o importante grupo de insetos aquáticos. O conhecimento da composição e riqueza desses insetos é de fundamental importância para entendermos como eles se organizam em comunidade. O objetivo deste estudo foi analisar se a sazonalidade exerce influência sobre as assembleias de larvas de Odonata. O trabalho foi realizado nos lagos Piaba e Viveiro do Parque Zoobotânico da Universidade Federal do Acre. As amostras foram realizadas no inverno de 2015 e verão de 2016. As amostras biológicas foram identificadas até o nível de gênero. Neste estudo confirmamos a hipótese de influência da sazonalidade sobre a fauna de odonatas e a importância da vegetação ciliar para preservação de espécies aquáticas em áreas urbanas.
