The biochemical properties of carotenoids from 2 species of freshwater bivalve, namely, Unio douglasiae nipponensis and Anodonta lauta, and 2 species of freshwater snail, namely, Cipangopaludina chinensis laeta and Semisulcospira libertina, were investigated. Diatoxanthin and fucoxanthin were identified as major carotenoids in both bivalves. In contrast, lutein and zeaxanthin were found to be t...
Predicting the impacts of non-native species remains a challenge. As populations of a species are genetically and phenotypically variable, the impact of non-native species on local taxa could crucially depend on population-specific traits and adaptations of both native and non-native species. Bitterling fishes are brood parasites of unionid mussels and unionid mussels produce larvae that parasi...
This study investigated the distribution of cadmium (Cd) and the protein level of metallothionein (MT) and examined the relationship of Cd accumulation and the MT concentration in different tissues of freshwater mussel Anodonta woodiana following Cd treatment. The mussels were exposed to Cd (4.21, 8.43, 16.86, 33.72 and 67.45 mg L-1) for 24, 48, 72 and 96 h, respectively. After Cd treatment, th...
The bivalve mollusc Anodonta cygnea appears to be unique in possessing the most dilute body fluids so far described in the Animal Kingdom. The osmotic concentration of the blood of this species has been found to amount to only about 44-0 m-osmole, with a sodium concentration which averages 15-6 mM/kg. (Potts, 1954). It is difficult to explain the ionic basis of electrical activity of excitable ...
The ability of natural zeolite (Clinoptilolite) to remove copper from aqueous ecosystem was studied in real and laboratory conditions. Fresh water mussels (Anodonta Cygnea) of different sizes were Exposed to copper (150, 350, 450 µgl-1) for 10 days. Copper exposure induced DNA damage in the haemolymph cells of Anodonta of all sizes. In connection with real samples, the amount of damage and even...
