Morphological and chemical characterization of mineral concretions in the freshwater bivalve Anodonta cygnea (Unionidae).
The freshwater mussel Anodonta cygnea is commonly used as a model organism for biomineralization studies, its peculiar morphofunctional properties also make it an excellent environmental biomonitor. The first detailed on the calcareous concretions from gill and mantle tissue, as well as fluids of the freshwater bivalve A. cygnea, supported by histological, scanning, spectrometry, and spectrosco...
متن کاملResponse of metallothionein concentrations in a freshwater bivalve (Anodonta grandis) along an environmental cadmium gradient
Surficial (oxic) sediments, overlying water, and specimens of the freshwater bivalve Anodonta grandis were collected by divers at 11 littoral lacustrine sites located along a geochemical gradient of pH, [Cd], Dl, and [Z n in an area influenced by mining and smelting activities. The molluscs were dissected (gills; 1 hepatopancreas; remaining tissues) and analyzed for Cd, Cu, Zn, and metallothion...
متن کاملEcosystem Level Effects of Marine Bivalve Aquaculture 51 ECOSYSTEM LEVEL EFFECTS OF MARINE BIVALVE AQUACULTURE
This paper reviews the present state of knowledge on environmental issues related to bivalve aquaculture, with emphasis on suspended mussel culture. Material reviewed includes Canadian and international studies on the role of wild and cultured bivalve populations in controlling ecosystem-level dynamics. The focus is on identifying potential changes in ecosystem processes (material and energy fl...
متن کاملOn the occurrence of Pinctada radiata (Mollusca: Bivalvia: Pteriidae), an alien species in Croatian waters
The family Pteriidae (Bivalvia: Pterioida), which includes the group of species known as “pearl oysters” comprises three genera, namely Pteria Scopoli, 1777, Pinctada röding, 1798 and electroma Stoliczka, 1871 (CLEMAM, 2008). This family is represented by three species (Pteria hirundo (Linné, 1758); Pinctada radiata (Leach, 1814) and electroma vexillum (Reeve, 1857)) in the Mediterranean accord...
متن کاملUranium in aragonitic marine bivalve shells
a r t i c l e i n f o Uranium concentrations in foraminiferal and coral skeletons track oceanic [CO 3 2 − ] and can be useful as a proxy of ocean acidification, but this pH proxy is yet to be investigated in bivalves. Two Saxidomus giganteus shells from the industrialized Puget Sound (WA, USA) and one from the more pristine Kodiak Island (AK, USA) were sampled through ontogeny for U/Ca using la...
