“…However, A. piguetti presented negative correlation with oxygen which suggests a sensibility of these individuals to the conditions of hypoxia and contrasts with some previous pieces of information about this species (e.g., Montanholi-Martins & Takeda, 2001).…”

“…Tubificinae subfamily had A. piguetti as the representative with greatest abundance. Although the occurrence of A. piguetti is also related to high values of organic matter, mud and low oxygen contents (Montanholi-Martins & Takeda, 2001). A. piguetti was dominant in different environments, where occurred high levels of oxygen (e.g., Osmar and Clara lakes) which, similarly to P. americana, demonstrates the environmental plasticity of the species.…”

Abstract: Aim: Identify the effects of sediment composition and water conditions on diversity, richness, evenness, density and composition of freshwater Oligochaeta in shallow floodplain lakes. Methods: We sampled 13 shallow floodplain lakes quarterly during the year 2010 in the Upper Paraná River floodplain. In each lake, four sediment samples were taken from the shore and central regions, three of them were used for biological analysis, and one for granulometric analysis. Concomitantly, temperature, dissolved oxygen, pH, conductivity, alkalinity, turbidity and chlorophyll-a were also measured. Initially, the biological samples were analyzed by a stereoscopic microscope. Oligochaeta individuals were identified under optical microscope at the lowest possible taxonomic level. For data analysis, we quantified density, richness, evenness and diversity index of freshwater Oligochaeta. In order to show differences between the months and the analyzed lakes, in relation to the percentages of coarse and fine organic material, the nonparametric Kruskal Wallis test was used. We also calculated the sediment granulometric diversity using the Shannon-Wienner index, using a simple regression analysis. We correlated assemblage attributes of Oligochaeta with sediment diversity and the assemblage species with the limnological variables using the Spearman correlation. Results: A total of 2,090 individuals were found distributed among 27 species. From the total individuals number, 57% were Pristina americana, followed by Dero (Dero) righii with 13%. Assemblage attributes were not significantly correlated with sediment diversity, and 7 of the 27 species recorded showed significant correlations with at least some of the abiotic variables. Conclusions: We verified that the abiotic variables of the water present greater influence on the attributes of the assemblage of freshwater Oligochaeta, when compared with sediment influences. Although we found low local diversity of this group, the wide range of water conditions offered by lakes culminates with a great species richness considering the whole landscape.

“…FAMILY ENCHYTRAEIDAE (Figure 4c) This family has high representation in terrestrial and semi-aquatic environments (Brinkhurst & Marchese 1989) and also occurs in typically aquatic environments, such as the plains of the upper Paraná River (Montanholi- Martins & Takeda 2001, Takeda 1999, preserved low-order streams , Gorni & Alves 2008b, lakes (Collado et al 1999) and the ocean (Lasserre 1971). Coates & Stacey (1994) reported that Enchytraeidae are less studied than others in South America and that most information is about semi-aquatic and terrestrial species.…”

Data resulting from species inventories shed light on the richness and distribution of various groups. In Minas Gerais, work on inventory and distribution of the oligochaetes of lotic environments in preserved areas are non-existent. Therefore, this study aimed to inventory the limnic oligochaetes fauna of first-order streams located in four preserved areas, to expand knowledge of the ecology and distribution of this group. In total, 19 taxa were inventoried, belonging to the families Naididae and Enchytraeidae and the superorder Megadrili (earthworms), with the genus Pristina having the largest number of species. The number of species found in this investigation corresponds to 22% of oligochaetes species recorded in Brazilian aquatic environments. The results obtained add important knowledge of the distribution of some oligochaetes species in Brazil, represent the first records of species for the four preserved areas studied and confirm the first occurrence of various species in the state.

Biota Neotrop. 13(1): http://www.biotaneotropica.org.br/v13n1/pt/abstract?inventory+bn02313012013Resumo: Os dados resultantes de um levantamento fornecem informações sobre a riqueza e distribuição de diversos grupos. Em Minas Gerais, trabalhos sobre inventário e distribuição de oligoquetas de ambientes lóticos em áreas preservadas são inexistentes. Dessa forma, este estudo objetivou inventariar a fauna de oligoquetas límnicos de córregos de primeira ordem localizados em quatro áreas preservadas, visando ampliar as informações sobre ecologia e distribuição deste grupo. Foram inventariados 19 taxa pertencentes às famílias Naididae, Enchytraeidae e à superordem Megadrili, sendo o gênero Pristina o de maior número de espécies. O número de espécies encontradas neste trabalho corresponde a 22% das espécies de oligoquetas registrados em ambientes aquáticos brasileiros. Os resultados obtidos ampliam o conhecimento sobre a distribuição de algumas espécies de oligoquetas no Brasil, representam os primeiros registros de espécies para as quatro áreas preservadas estudadas e confirmam a primeira ocorrência de várias espécies no Estado. Palavras-chave : biodiversidade, Campos Rupestres, Mata Atlântica, Naididae, folhiço, oligoquetas, Enchytraeidae. Martins et al. ( , 2011 and Suriani-Affonso et al. (2011), the number in the state has increased to 23. The true number is probably even higher, because ecological studies often record new species not considered in official records. In this context, the present study aimed to inventory the limnic oligochaete fauna in first-order streams in preserved areas, to expand the information about the ecology and distribution of this group.

“…In the present literature, N. schubarti occurrence records in Brazil were limited to two Brazilian states: Pernambuco (Marcus, 1944;Righi, 1984;Christoffersen, 2007), and Paraná (Montanholi-Martins and Takeda, 2001;Christoffersen, 2007); being recognized as an endemic species of South America (Christoffersen, 2007). However, it is probable that N. schubarti occurs in other Brazilian aquatic ecosystems, due to the scarcity of studies that aim at the survey of oligochaete species in Brazilian aquatic ecosystems, as well as the lack of specialists in the taxonomic identification of these worms.…”
