“…In addition, these worms have limited mobility and are influenced by the habitat characteristics in which they are found (Behrend et al 2012). Thus, the richness and abundance of Oligochaeta is directly related to environmental variables (Marchese & Drago 1999, Jablonska, 2014, such as availability of food resources (Martins & Silveira, Alves 2011); dissolved oxygen (Dornfeld et al 2006); type of substrate (Moretto et al 2013); water temperature (Nascimento & Alves 2009), thus being considered indicators of specific habitats.…”

Oligochaeta (Annelida: Clitellata) in the Juruena River, MT, Brazil: species indicators of substrate types

Oligochaeta assemblages are important components in freshwater environments, where their abundance and composition may indicate aspects related to water quality and sediment. The lack of information about these communities in Brazilian aquatic environments, as well as the application of native species as bioindicators of lotic environmental, stimulated the conception of this paper. Thus, the aim was to study the community of aquatic Oligochaeta in selected stretches of the Juruena River (MT), thereby generating grounds for future environmental monitoring action in lotic ecosystems. For this purpose, samples were analyzed at bimonthly intervals during the period from January to November 2009, in stretches of the Juruena River (Amazon River Basin) located in the State of Mato Grosso (MT). Two methods were used to collect the organisms: a) "D" network in small clusters of fixed macrophytes in the sediment on the river banks; and b) Ekman-Birge dredge in fine sediment. Preliminary results were 584 organisms distributed in 22 taxa. Of these, 22 valid species were identified. This number corresponds to approximately 25% of the aquatic oligochaete species registered in Brazil. Of these species, Limnodrilus hoffmeisteri, Dero nivea and Pristina rosea can be associated with organic enrichment conditions and/or some level of environmental degradation.

“…The other factor analyzed was the source of organic matter: commercial fish feed (FF; 38% of crude protein), commercial poultry feed (PF; 23.5% of crude protein), and turkey manure (TM; 16.5% of crude protein). The quantity of organic matter offered was 0.02 g per individual, the same used by Nascimento and Alves (), which was offered twice a week after measurement of water temperature, pH, and dissolved oxygen concentration made with a multiparameter YSI‐63 and with an oxymeter YSI‐550A.…”

This study aimed to assess the combined effects of density of adults of Branchiura sowerbyi and the source of organic matter on the production of eggs and young species. The experimental units used were 250-mL beakers with 100 mL of fine sand (0.074-0.210 mm) and 150 mL of chlorine-free water with constant aeration at the temperature 25 C. The experiment was conducted based on a two-factor model with six treatments and three repetitions, applied in a completely random design. The densities 5 individuals/38.5cm 2 (D5; 1298/m 2 ) and 8 individuals/38.5cm 2 (D8; 2078/m 2 ) were assessed with commercial fish feed (FF), commercial poultry feed (PF), and turkey manure (TM) as sources of organic matter. A total of 1223 cocoons and 2138 eggs were produced, with average hatching of 40.0 ± 15.1%. The highest number of cocoons and eggs was found with the use of PF, D8 having produced the highest number of cocoons and eggs. The hatching rate was not influenced by the source of organic matter or density and no influence was registered from the density of adults on the survival. The PF provided the highest growth of adults, and generally the use of TM provided the worst performance.

“…Essa espécie é um tubificínio comum em vários habitas, mas é mais facilmente encontrada em ambientes poluídos (BRINKHURST; MARCHESE, 1989), sendo assim amplamente utilizado como um indicador de poluição orgânica LUCCA, 2000;DORNFELD et al 2006). Além disso, a reprodução dessa espécie é favorecida em sedimentos finos (LOBO; ALVES, 2011) e temperaturas mais altas de 23 a 25ºC (NASCIMENTO;ALVES, 2009). Neste estudo, esteve presente em maior número no Ribeirão da Bocaina (P7) na estação chuvosa e representou 10,25% da amostra total.…”

Os inventários de espécies fornecem amplo conhecimento sobre a distribuição, ecologia e riqueza dos táxons tornando-o uma ferramenta importante para programas de conservação de biodiversidade e gestão dos ecossistemas. Os organismos inventariados neste estudo são pertencentes à classe Oligochaeta, um importante táxon da fauna aquática continental e um dos grupos mais importantes na ciclagem de matéria orgânica nos ecossistemas de água doce. Dessa forma, este estudo tem como objetivo realizar o levantamento das espécies de Oligochaeta em três córregos urbanos (Córrego Himalaia, Ribeirão da Bocaina e Córrego Bocaina) do município de Bocaina, localizado na região central do estado de São Paulo. Para isso, as amostras de sedimento foram coletadas em sete pontos com o auxílio de uma rede (malha 0,25 mm) pelo método de varredura. O material coletado foi triado para obtenção dos organismos, fixado com formalina 10% e identificado até nível de espécie. Foram registrados 20 táxons de um total de 1395 organismos, distribuídos em 10 gêneros (Allonais, Aulophorus, Bothrioneurum, Brinkhurstia, Dero, Limnodrilus, Nais, Opistocysta, Pristina e Slavina) e 4 famílias: Família Naididae Opistocystidae, Alluroididae e Enchytraeidae. Assim, o presente inventário obteve uma riqueza de 20 táxons, representando aproximadamente 23% das 86 espécies registradas em ecossistemas aquáticos brasileiros. Por fim, muitos estudos ainda precisam ser realizados para fornecer dados mais completos sobre a distribuição e ecologia desse táxon, para enfatizar sua importância como bioindicadores de qualidade da água e para manutenção do equilíbrio ecológico em ambientes aquáticos.
