“…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).…”

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.

“…Puede tolerar períodos de hipoxia (Fischer and Beeton 1975) y posee mecanismos de resistencia a la contaminación por metales (Klerks and Bartholomew 1991). Por otro lado, A. pigueti es un taxón reportado como el oligoqueto tubificino más abundante en embalses eutróficos de Sudamérica (Moretto et al 2013;Ragonha and Takeda 2014;Girolli et al 2021).…”

El Embalse Río Hondo es un ambiente muy poluído para el que los antecedentes de estudios biológicos aún son escasos. En este trabajo se caracteriza la diversidad de macroinvertebrados bentónicos y se aplica el índice multimétrico ICBRES, desarrollado para embalses. Se realizó un muestreo de macroinvertebrados, sedimentos y variables fisicoquímicas del agua en 6 sitios dentro del embalse. La temperatura media fue 19.3±2.2 °C, el pH fue 8±0.4, la conductividad eléctrica fue 656±13.3 µS/cm y el oxígeno disuelto fue 9.4±1.5 mg/L. La profundidad varió entre 1.3 y 16 m, y la transparencia osciló entre 0.25 y 0.70 m. En los sedimentos prevalecieron la arena fina, los limos y las arcillas. La densidad de organismos varió entre 0 y 23819±10312 individuos/m2. El 93.5% perteneció a Oligochaeta, el 4.1% a Chironomidae, el 2.2% a otros grupos bentónicos y el 0.2% a insectos no Chironomidae. La riqueza total fue 32 taxones y el índice de Shannon alcanzó un valor global de 1.63. Los oligoquetos más abundantes fueron Limnodrilus hoffmeisteri Claparède 1862 y Aulodrilus pigueti Kowalewski 1914. Entre los quironómidos, los más abundantes fueron Clinotanypus y Procladius. El índice aplicado clasificó la calidad del agua de buena a muy mala en los diferentes sitios. La baja diversidad y dominancia de organismos tolerantes reflejan las condiciones de contaminación y degradación ambiental del embalse. Se considera prometedor el potencial para desarrollar herramientas de biomonitoreo en base a macroinvertebrados bentónicos en el Embalse Río Hondo.

“…Among aquatic invertebrates, the oligochaetes (Clitellata, exclusive of leeches) are well diversified (Creuzé des Châtelliers, Juget, Lafont, & Martin, 2009; Martin, Martinez‐Ansemil, Pinder, Timm, & Wetzel, 2007) and play an essential role in fine sediment bioturbation (Nogaro et al, 2006), nutrient redistribution (Fukuhara & Sakamoto, 1987), and several biogeochemical processes (Anschutz, Ciutat, Lecroart, Gérino, & Boudou, 2012; Chauvet, Giani, & Gessner, 1993). They are sensitive to the chemical water quality (Rodriguez & Reynoldson, 2011; Vivien, Lafont, Werner, Laluc, & Ferrari, 2019) and sediment characteristics (Ragonha & Takeda, 2014) as well as the trophic level of the ecosystem (Armendáriz, Ocón, & Capítulo, 2012). Based on their ecological requirements, species can be assigned to stygoxenes (restricted to surface water and rarely occurring inside hyporheic sediments), stygophiles (living in both surface and hyporheic zones), or stygobites (restricted to groundwater; Marmonier, Vervier, Gibert, & Dole‐Olivier, 1993).…”

River‐groundwater exchanges are crucial for several ecological processes, but difficult to localize. Hyporheic oligochaetes may represent efficient biological indicators of these exchanges, but hydrological disturbance may alter oligochaete distribution and blur the spatial patterns of river‐groundwater exchanges. Oligochaete assemblages were compared in the Drôme River, which is a semi‐natural braided river with an unmodified discharge, and the Ain River, which has reduced sediment mobility and hydropeaking due to several upstream dams. In the semi‐natural river, the oligochaete distribution was mostly controlled by the origin of the water: some stygoxene species (e.g., Chaetogaster spp. and Vejdovskyella intermedia) were restricted to or more abundant in downwellings, whereas a set of stygophiles (e.g., Stylodrilus sp. and Cernovitoviella sp.) and stygobites (e.g., Aberrantidrilus cuspis) were present or more abundant only in upwellings. Species living in fine sediment (e.g., Potamothrix sp. and Tubifex sp.) also occurred in upwellings due to their location at the border of the braided strip. Conversely, in the regulated river, oligochaete assemblages were abundant and diversified, with species living in fine sediment being dominant in the partially clogged stations. The spatial distribution of most species did not follow typical surface‐hyporheic exchange patterns: most stygophiles (e.g., Proppapus volki and Marionina argentea) and some stygobites (e.g., Haber turquini) were found in both upwellings and downwellings or even at stations without water exchanges (e.g., Rhyacodrilus balmensis). In rivers subjected to hydrological disturbance and hydropeaking, oligochaetes became poor indicators of river‐groundwater exchanges.
