“…Chen, 1940 (Figure 3a) It occurs in East Asia and South America (Argentina, Ecuador, Venezuela, Chile, Brazil and Guiana). In Brazil it has been reported by associated with macrophytes in reservoirs in the state of São Paulo, by Gorni & Alves (2008b) in low-order streams, by Gorni & Alves (2008a) associated with sponges in a reservoir in São Paulo and by Montanholi-Martins & Takeda (1999) in segments of the upper Paraná River. This species was only found in a riffle of one stream in a Semideciduous Seasonal Forest area.…”

“…In South America it has been reported in Chile, Argentina, Bolivia, Peru, Ecuador, Venezuela, Colombia, Guiana, Suriname and Brazil (São Paulo, Mato Grosso do Sul and Pará). It has been found in a wide range of environments, such as the upper Paraná River (Montanholi- Martins & Takeda 1999, urban streams (Alves & Lucca 2000), lakes with different trophic states (Collado & Schmelz 2001a) and reservoirs (Pamplim et al 2005). In the present study it was only found in streams flowing through Semideciduous Seasonal Forest areas.…”

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.

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.

“…The species is usually associated with highly polluted environments (Marchese 1987;Montanholi-Martins & Takeda 1999;Takeda 1999;Ezcurra de Drago et al 2004;Marchese et al 2005). Other authors also recorded L. hoffmeisteri in the shallow organically enriched sediments of lakes (Casellato & Caneva 1994) as well as in estuaries, in both the freshwater and brackish sectors (Moroz 1994;Finogenova 1996;Seys et al 1999).…”

“…This species is frequently found in the main stretch of the Lower Paraguay and Parana´rivers Montanholi-Martins & Takeda 1999;Ezcurra de Drago et al 2004;Marchese et al 2005). In the Rı´o de la Plata, this species has been previously recorded in the sandy sediments of the upper section (Armenda´riz & Ce´sar 2001;Cortelezzi et al 2007).…”

“…The macroinvertebrates in the Rı´o de la Plata River have been studied by a number of authors Darrigran & Lo´pez Armengol 1998;Rodrigues Capı´tulo et al 1998Ce´sar et al 2000;Cortelezzi et al 2007), while the species composition and ecological requirements of oligochaetes in particular have been analysed during recent years in other larger rivers in South America (Montanholi-Martins & Takeda 1999;Takeda 1999;Ezcurra de Drago et al 2004;Marchese et al 2005). Furthermore, in various parts of the world, studies on the oligochaete fauna from temperate estuaries subjected to anthropogenic impact have indicated that the most significant environmental factors affecting their distribution are the salinity, turbidity, discharge, trophic condition, sediment characteristics and general quality of the bodies of water in question (Moroz 1994;Finogenova 1996;Gonza´lez-Oreja & Saiz-Salinas 1999;Seys et al 1999).…”

The oligochaete assemblage on the Argentine coast of the Rı´o de la Plata estuary was sampled seasonally within environments having different types of disturbances. Three habitats were sampled: sediments free of vegetation, sediments within bullrush stands and substrates with Limnoperna fortunei. The species richness, evenness and ShannonÁWiener diversity values were different among those habitats. The only dominant species (according to the Kownacki index) was Nais variabilis. Mean density values varied between 400 and 199,500 ind./m 2 . Organic matter, ammonium and phosphates correlated positively with the mean oligochaete abundance, but not with the granulometry. Physicochemical variables and nutrient levels were measured and their relation to the sampling sites assessed through a principal component analysis (41.8% cumulative variance). The canonical correspondence analysis (41.2% cumulative variance) indicated that the oligochaetes distributed along both a eutrophicationÁpollution gradient and a turbidityÁconductivity gradient. These results would be useful for assessing the ecological status of estuaries for a subsequent implementation of appropriate sustainability-management policies.
