Depuration kinetics and persistence of the cyanobacterial toxin microcystin-LR in the freshwater bivalve Unio douglasiae.
We carried out uptake and depuration experiments in the laboratory to investigate the effects of temperature (15 degrees C and 25 degrees C) on the depuration kinetics and persistence of a cyanobacterial toxin, microcystin-LR (MCYST-LR), in a freshwater bivalve, Unio douglasiae. Bivalves were fed toxic Microcystis cells in the 15-day uptake experiment and nontoxic diatoms in the following 15-da...
متن کاملHost specificity and metamorphosis of the glochidium of the freshwater mussel Unio tumidiformis (Bivalvia: Unionidae).
The glochidium larvae of freshwater mussels of the family Unionidae need to find suitable hosts to attach themselves and metamorphose into free-living juveniles. The specificity of the host-parasite relationship was investigated for the Iberian Unio tumidiformis Castro, 1885 by means of experimental infections and also by analyzing naturally infected fish. The process of encapsulation of glochi...
متن کاملMorphological 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 کاملIdentification of carotenoids in the freshwater shellfish Unio douglasiae nipponensis, Anodonta lauta, Cipangopaludina chinensis laeta, and Semisulcospira libertina.
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...
متن کاملLong-Term Decline in Freshwater Mussels (Bivalvia: Unionidae) of the Western Basin of Lake Erie
Long-term trends in the abundance of unionids in the western basin of Lake Erie were examined from data collected at 17 stations in 1961, 1972, and 1982. The mean number of unionids at these stations declined over this time period, decreasing from 10 m~2 in 1961, to 6 m~2 in 1972, down to 4 m~2 in 1982. This decline in abundance was reflected in the decrease in the number of stations where muss...
