Taxonomy and new bacterial symbioses of gutless marine Tubificidae (Annelida, Oligochaeta) from the Island of Elba (Italy)
In shallow sublittoral sediments of the north-west coast of the Island of Elba, Italy, a new gutless marine oligochaete, Olavius ilvae n. sp., was found together with a congeneric but not closely related species, O. algarvensis Giere et al., 1998. In diagnostic features of the genital organs, the new species differs from other Olavius species in having bipartite atria and very long, often folde...
متن کاملFirst record of Limnodrilus claparedeianus Ratzel, 1868 (Annelida: Oligochaeta: Tubificidae) in Anzali Wetland, Guilan province, Iran
Oligochaeta worms are important organisms in aquatic ecosystem. Their omnipresence makes them as an indicator of environmental changes and health of aquatic ecosystem. The members of the family Tubificidae and in particular, genus Limnodrilus are considered as the most tolerant oligochaets to aquatic pollution. Therefore identification and biological characteristics of this taxon are of great h...
متن کاملEffects of 5-Fluorouracil, Etoposide and CdCl2 in Aquatic Oligochaeta Limnodrilus udekemianus Claparede (Tubificidae) Measured by Comet Assay
Genotoxicity of 5-fluorouracil (5-FU), etoposide (ET) and cadmium chloride (CdCl2) was evaluated in Limnodrilus udekemianus, cosmopolitan tubificid species, by alkaline single-cell gel electrophoresis (comet assay). Groups of 50 individuals were exposed in vivo in water-only short-term (96 h) tests to 5-FU (0.004, 0.04, 0.4, 4 and 40 μM), ET (0.004. 0.04, 0.4 and 4 μM) and CdCl2 (0.004, 0.04, 0...
