In vitro culture of glochidia from the freshwater mussel Anodonta cygnea

In Vitro Culture of Freshwater Pearl Mussel from Glochidia to Adult

comparison of zinc and chromium bioaccumulation in the internal organs of freshwater mussel anodonta cygnea (bivalvia: :union:idae)

nowadays, bivalves are used in monitoring levels of heavy metals in aquatic environments. the aim of this study was to investigate bioaccumulation of heavy metals zinc (zn) and chromium (cr) in the internal organs of anodonta cygnea. for this purpose, bivalve specimens were collected from semeskandeh region, sari, and then in laboratory, were exposed to 125 µg l-1 concentrations of each metal f...

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...

Factors affecting the heart activity and blood pressure of the swan mussel Anodonta cygnea.

1. The rate of heart beat increased with temperature and was three times as high in the active as in the inactive animal. 2. The rate of shell valve movement rose and the rate of heart beat fell when the foot was extended. 3. The rates of heart beat and shell valve movement decreased when the water was saturated with carbon dioxide. This heart response remained when the visceral ganglion was de...

Seasonal changes in the behaviour and respiration physiology of the freshwater duck mussel, Anodonta anatina.

For low-energy organisms such as bivalves, the costs of thermal compensation of biological rates (synonymous with acclimation or acclimatization) may be higher than the benefits. We therefore conducted two experiments to examine the effect of seasonal temperature changes on behaviour and oxygen consumption. In the first experiment, we examined the effects of seasonal temperature changes on the ...
