Freshwater Bivalves (Unionidae), Disequilibrium Isotopic Fractionation, and Temperatures
PALAIOS, 1993A one-year study of two ponds and one river in Rhode Island was implemented to determine whether Recent freshwater bivalves (Unionidae: Elliptio complanata) secrete aragonite in oxygen isotopic equilibrium with the water in which they grow. Water samples and animals were retrieved from each locality at two-week intervals for one year.

Microboring in a Freshwater Fluvial Unionid Bivalve Substrate
Ichnos, 2014Samples of the unionid bivalve Elliptio complanata were collected from the channel of the freshwater Saint John River, from Fredericton, New Brunswick, Canada. Scanning electron microscopy imaging of prepared shell samples revealed an assemblage of microborings. No borings are noted on the periostracum or prismatic shell layers.

Interspecific differences in manganese levels in freshwater bivalves
Water, Air, and Soil Pollution, 1989Vital effects may be important in determining metal levels in bivalves and must be taken into account before the environmental ‘meaning’ of the data may be interpreted. Manganese concentrations in shells and soft tissues of several species of freshwater bivalves from three recent environments in northern Ohio and one archeological site from southern ...

Evaluation of Bivalves as Bioindicators of Metal Pollution in Freshwater
Bulletin of Environmental Contamination and Toxicology, 2011The fresh water bivalves, Lamellidens corrianus, Lamellidens marginalis, and Indonaia caeruleus were exposed to chronic concentration of arsenic (0.1719 ppm), cadmium (0.1284 ppm), copper (0.033 ppm), lead (1.50 ppm), mercury (0.0443 ppm) and zinc (1.858 ppm) separately up to 30 days in laboratory.

A systematic review of invasive non‐native freshwater bivalves
Biological ReviewsABSTRACTThe introduction of invasive species has become an increasing environmental problem in freshwater ecosystems due to the high economic and ecological impacts it has generated. This systematic review covers publications from 2010 to 2020, focusing on non‐native invasive freshwater bivalves, a particularly relevant and widespread introduced ...

Filtration rate capacities in 6 species of European freshwater bivalves
Oecologia, 1988Filtration rate capacities in undisturbed freshwater bivalves were determined by means of two different methods (indirect "clearance" and "suction" methods) in Anodonta anatina (L.), Unio tumidus Philipsson, Unio pictorum (L.), Unio crassus Philipsson, Dreissena polymorpha (Pallas) and Sphaerium corneum (L.). In A. anatina, D.

Chronic Toxicity of Ammonia to the Freshwater Bivalve Sphaerium novaezelandiae
Archives of Environmental Contamination and Toxicology, 1999The chronic toxicity of total ammonium and unionized ammonia (NH3) to the native New Zealand freshwater fingernail clam Sphaerium novaezelandiae was assessed in soft water under laboratory conditions. Control survival after 60 days was high (93%) and concentration-response relationships showed the sensitivity of S.

Copper induces cytotoxicity in freshwater bivalve Anodonta woodiana hemocytes
ChemosphereHemocytes of freshwater bivalves are an important target model for evaluating copper (Cu) toxicity in vitro, with excess Cu causing adverse responses in these organisms. Despite this, the mechanisms underlying cytotoxicity remain poorly understood. The freshwater bivalve Anodonta woodiana, employed as a model organism in freshwater environments, was ...

Norfluoxetine Induces Spawning and Parturition in Estuarine and Freshwater Bivalves
Bulletin of Environmental Contamination and Toxicology, 2008Fluoxetine, a commonly prescribed antidepressant (Prozac), has been detected in sewage effluent. Its active metabolite norfluoxetine is more potent and has been detected in sewage influent and in fish tissues. We tested the effects of norfluoxetine on spawning and parturition in bivalves.
