Effect of selenium exposure on the freshwater bivalve Corbicula fluminea
Selenium is essential for most of living organisms. In normoxic to moderately hypoxic freshwaters, Se exists predominantly in the (+VI) and (+IV) oxidation states as selenate and selenite respectively, whereas in the biota it is incorporated as Se (-II) or Se (0). At low concentrations, it acts against oxidative damages, but it may be toxic at higher levels. In filter feeders, such as the fresh...
متن کاملEffects of the invasive bivalve Corbicula fluminea on settling juveniles and other benthic taxa
The Asian clam Corbicula has become established worldwide in a wide range of freshwater ecosystems. Corbicula fluminea invaded Lake Constance (Central Europe) between 2000 and 2002 and has reached densities up to 3520 individuals .5 mm in length per square meter in sandy areas. However, the effect of this species on other benthic invertebrates remains unclear. Here, we show that ecosystem engin...
متن کاملEarly defense responses in the freshwater bivalve Corbicula fluminea exposed to copper and cadmium: Transcriptional and histochemical studies.
The aim of the present study was to measure the early effects of copper (10 and 50 μg L(-1)), cadmium (2, 10, and 50 μg L(-1)) and mixtures of these metals in the freshwater bivalve Corbicula fluminea exposed for 12 h in laboratory. Transcription levels of superoxide dismutase (SOD), catalase (CAT), selenium-dependent glutathione peroxidase (Se-GPx), pi-class glutathione S-transferase (pi-GST),...
متن کاملFlotation of the Bivalve Corbicula fluminea as a Means of Dispersal.
Small specimens of the Asiatic bivalve Corbicula c.f. fluminea (Müller) secrete long mucous threads through their exhalent siphons that act as draglines to buoy the animal into a water column. These mucous strands, secreted in response to water current stimuli, are produced by dense accumulations of ctenidial mucocytes and may help in the downstream or interstream dispersal of this rapidly spre...
متن کاملGenetic damage in the bivalve mollusk Corbicula fluminea induced by the water-soluble fraction of gasoline.
Although gasoline is an important contaminant of aquatic ecosystems, information concerning the potential effects of this petroleum derivative on the DNA of aquatic biota is lacking. The present study aimed to evaluate the genotoxic and mutagenic effects of acute exposures (6, 24, and 96h) to gasoline water-soluble fraction (GWSF), diluted to 5%, on the Asian clam Corbicula fluminea. The comet ...
