The Effect of Dieoffs of Asian Clams (Corbicula fluminea) on Native Freshwater Mussels (Unionidae)
… suggested that the exotic Asian clam, Corbicula fluminea, may be having an effect on native unionids. Negative impacts may result directly from competition or indirectly, because of Corbicula population crashes that release ammonia and reduce dissolved oxygen in the sediment. Laboratory tests …

Abiotic and biotic factors influencing the decline of native unionid mussels in the Clinch River, Virginia
… of sediment toxicants or adult Corbicula fluminea in the depositional areas, the preferred habitat of the juveniles. Before investigating the impacts of these factors, it was necessary to characterize the relationship of the juveniles with the sediment they inhabit. Observations of feeding …

An Ecotoxicological Recovery Assessment of the Clinch River Following Coal Industry-related Disturbances in Carbo, Virginia (USA): 1967-2002
… and growth of field-caged Asian clams (Corbicula fluminea) at sites downstream of the CRP. More importantly, these results indicated renewed toxicity in CRP effluent. Additional transplant studies using two enclosure types were conducted to isolate effects attributable to CRP effluent from the …

Implications of Shape Factors on Fate, Uptake, and Nanotoxicity of Gold Nanomaterials
… a fresh water filter-feeder bivalve, Corbicula fluminea, can be used as a model organism to study the size and shape-selective biofiltration and nanotoxicity of elongated gold nanoparticles. The results suggest that biofiltration by C. fluminea increases with an increase in the size and AR of …

Prevention, Control and Eradication of Aquatic Invasive Species
… polymorpha) mussels, Asian clam (Corbicula fluminea), killer shrimp (Dikerogammarus villosus), and bloody red shrimp (Hemimysis anomala). Each species was independently exposed to aquatic disinfectants or steam spray treatments (≥100 °C). Dikerogammarus villosus, and H. anomala were also …

A multidisciplinary study of the Asiatic clam, Corbicula fluminea, from the New River, Virginia
… were conducted with the Asiatic clam, Corbicula fluminea, that examined seasonal periodicities in spawning, body condition, and percent tissue water content. In addition, responses of adults to brief (24 hr) and extended (30 d) periods of exposure to toxicants were investigated. These studies …

Hydrologic-Based Ecological Risk Assessment of Urban, Agriculture, and Coal Mining Impacts Upon Aquatic Habitat, Toxicity, and Biodiversity
… techniques instream; and (5) in situ Corbicula fluminea growth rates were dependent upon drainage area. Sporadic signs of agricultural and urban impacts were indicated from acute toxicity with Ceriodaphnia dubia and chronic in situ toxicity testing with C. fluminea. Both the ecotoxicological …

The Effect of Speciation and Form on the Bioavailability of Arsenic: Insight into the Behavior of Arsenic in Natural Waters
… bioavailability of As species to Corbicula fluminea, a clam commonly used for biomonitoring. Results demonstrate that As(III) is most bioavailable to Corbicula, followed by As(V), MSMA, and roxarsone. Corbicula also displayed the ability to change As speciation through internal processing …
