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

چکیده
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.

The aim of this study was to evaluate the presence of Chaetogaster limnaei K. von Baer, 1927 in four species of mollusks collected in irrigation channels of a horticultural garden in the city of Juiz de Fora, Minas Gerais State, Southeastern Brazil. The collections were made from June 2005 to January 2006. Of the four species of mollusks analysed, we could not detect the presence of C. limnaei ...

The cosmopolitan oligochaete worm, Nais elinguis, is common to fresh and brackish water habitats. This species was found while investigating the limnology of two rivers alongside the Iranian coasts and has not been reported in the Iranian freshwater fauna and Caspian Sea before. N. elinguis was collected bimonthly from Cheshmehkileh and Sardabrood estuaries using a Van Veen grab (0.03 m2) and S...

The new species is distinguished from congeners by its large area of reddish brown pigment in the anterior segments I-VIII, serrate hairs, pectinate needles with 1-2 intermediate teeth, ventral chaetae partly wit...
متن کاملMicrodrile Oligochaeta in bromeliad pools of a Honduran cloud forest.
Phytotelmata, or plant-held water bodies, often house complex aquatic invertebrate communities. Microdrile oligochaetes (Clitellata, Annelida) are known to be part of that community, but specimens are rarely identified to species level. Here we report three species of Enchytraeidae and three species of Naididae from a collection sampled in phytotelms of bromeliads in Cusuco National Park, Hondu...

Amphibians are hosts for a wide variety of ecto- and endoparasites, such as protozoans and parasitic worms. Naididae is a family of Oligochaeta whose species live on a wide range of substrates, including mollusks, aquatic macrophytes, sponges, mosses, liverworts, and filamentous algae. However, some species are known as endoparasitic from vertebrates, such as Dero (Allodero) lutzi, which is par...
