The Coosa Elktoe, Alasmidonta mccordi Athearn, 1964, was previously known only from the type specimen collected in River, St. Clair County, Alabama. Based on discovery of five misidentified specimens three museum lots, we extend distribution A. into Etowah and Conasauga Rivers, tributaries River northwest Georgia. Shell morphology these compare favorably with species. conservation status is exa...

Domoic acid (DA) accumulation was studied in Mytilus galloprovincialis collected from rafts in Ría de Vigo, Spain, during short-term lab experiments. Mussels were fed Pseudo-nitzschia multiseries cultures (1900, 3800, 6000 cells/ml) and P. multiseries blooming in a phosphorus limited mesocosm. Toxin concentration in mussel whole tissue was proportional to toxin offered in food except for the lo...

Environmental pollution due to antibiotics is a serious problem. In this work, the adsorption and desorption of antibiotic cefuroxime (CFX) were studied in four by-products/residues from forestry food industries. For this, batch-type experiments carried out, adding increasing concentrations CFX (from 0 50 µmol L?1) 0.5 g adsorbent. The materials with pH higher than 9 (mussel shell wood ash) tho...

Abstract Mussel shells are often found in archaeological excavations and can provide information useful for ecological reconstruction assessment of anthropogenic impact on waters. In this study, two sample groups swollen river mussel ( Unio tumidus ) which occurred during the Early Middle Ages (EMS) currently (MS) Oder estuary (Baltic basin) were compared. Allometric shell growth, morphological...

Byssogenesis rate and attachment strength of the mussel Mytilus galloprovincialis were investigated in the laboratory considering different body sizes and feeding conditions. Byssal thread secretion was significantly higher in juveniles as compared to larger mussels of approximately 87 mm shell length. Asymptotic number of threads attached was obtained from approximately 72 hours onwards within...

The intertidal clam, Glauconome virens, was collected in the northwestern portion of Peninsular Malaysia near Kuala Perlis, Sungai Layar, and Pantai Teluk Air Tawar. This research attempted to determine cadmium (Cd) lead (Pb) concentrations various G. virens’s organs. Cd (mg/kg dry weight) five distinct soft tissues ranged from 0.90 1.89, but shells 0.95 1.25. Pb 27.0 44.9, whereas shell 74.8 7...
