Oligochaetes (Annelida, Clitellata) in a neotropical stream: a mesohabitat approach

Abstract: ABSTRACT. This paper analyses the relationship among mesohabitat and aquatic oligochaete species in the Galharada Stream (Campos do Jordão State Park, state of São Paulo, Brazil). Between August 2005 and May 2006 a total of 192 samples were obtained in areas of four different mesohabitats: riffle leaf litter (RL), pool leaf litter (PL), pool sediment (PS) and interstitial sediment from rocky beds in riffle areas (IS). In the mesohabitats sampled, 2007 specimens were identified, belonging to two families (Naidi… Show more

“…The streams studied all fit this description, so this may have contributed to the presence of Enchytraeidae in the bryophytes analyzed. The species of oligochaetes collected in this study are also associated with other microhabitat types, such as fine sediments, sand and stones, in both riffles and pools (Schenková et al, 2001;Alves et al, 2008;Gorni and Alves, 2008;Behrend et al, 2009;Baturina, Gorni and Alves, 2012;Rodrigues et al, 2013a). Hence, there are no indications that a particular species is restricted to inhabiting bryophytes.…”

“…Previous studies have demonstrated that the richness and distribution of oligochaetes could be influenced by the substrate composition and heterogeneity (Dumnicka, 1994;Martínez-Ansemil and Collado, 1996;Schenková and Helešic, 2006;Gorni and Alves, 2012), the quality and availability of food (Learner et al, 1978;Collado and Schmelz, 2001) as well by the water flow, although there isn't a clear relation between the last variable and their distribution. (Verdonschot, 2001).…”
