Occurrence of Naididae (Annelida: Oligochaeta) from three gastropod species in irrigation fields in southeastern Brazil

Abstract

Abstract:In the present study we report the occurrence of three Naididae species from three gastropod mollusk species. The species Dero (Dero) righii was found from mollusks of the genus Biomphalaria. Nais communis was found from Biomphalaria sp. and Aplexa rivalis. Chaetogaster limnaei was found from Biomphalaria sp., Aplexa rivalis and Lymnaea columella. In Brazil, previous studies have reported the occurrence of Chaetogaster limnaei from Biomphalaria solely, while Nais communis have been found from Pomacea bridgesii and Dero (Dero) righii in the sediment of aquatic habitats in Mato Grosso do Sul. Our results indicate that, due to their locomotion, naidids are capable of colonizing different substrates in aquatic environments.

First report of Chaetogaster limnaei (Annelida: Naididae) in Chile based on samples retrieved from an invasive freshwater snail

“…This subspecies separation is not supported by recent molecular phylogenetic analysis based on COI sequences, which provides evidence that these forms belong to the same taxonomic entity (Smythe et al, 2015). In South America, C. limnaei has been found associated with snails Aplexa rivalis (Maton & Rackett, 1807) (Physidae), Biomphalaria straminea (Dunker, 1848) (Planorbidae) and Pseudosuccinea columella (Say, 1817) (Lymnaeidae) in Brazil (Callisto et al, 2005;Martins & Alves, 2008. Di Persia (1980) found C. limnaei in Argentina.…”

New records of Naidid worms (Oligochaeta: Naididae) in Euphrates River

“…Species of Naididae worms commonly inhabit sediments of rivers, streams and lakes (1). Due to their great ability to swim, they may have eyes, and are capable of exploring benthic habitat, (2) such as aquatic macrophytes (3), mosses and liverworts; (4) , filamentous algae (5), sponges (6),and gastropod mollusks (7&8).…”

Record of Haplotaxis aedeochaeta Brinkhurst & Marchese, 1987 (Oligochaeta: Haplotaxidae) in a conservation unity in the state of São Paulo

“…In continental aquatic ecosystems, it is composed of more than 1.100 known species (Martin et al, 2008), which play an important role in the decomposition process as most species are detritivorous (Rodriguez and Reynoldson, 2011). These organisms can be found in several microhabitats in aquatic environments, living in sediment or in water columns (Rodriguez and Reynoldson, 2011) and in association with other organisms (Corbi et al, 2004(Corbi et al, , 2005Gorni and Alves, 2007;Martins and Alves, 2008;Oda et al, 2015). In addition, they have limited mobility and are influenced by habitat characteristics (Behrend et al, 2012), which make them efficient bioindicators of water quality.…”
