Esterases in the zebra mussel Dreissena polymorpha: activities, inhibition, and binding to organophosphates
Cholinesterase activities of Dreissena polymorpha were measured calorimetrically. In homogenates of whole control mussel, activities of 125 f29 pmol min-’ kg-’ were found (n=6). Neither after exposure of Dreissena to organophosphates (thiometon, disulfoton, demeton-Smethyl) nor after addition of demeton-S-methyl (the activated oxygen analogue of thiometon) in vitro was the measured mussel ester...
متن کاملOrganophosphates in the zebra mussel Dreissena polymorpha: subacute exposure, body burdens, and organ concentrations.
Subacute exposures (10 d) of the freshwater mollusc Dreissena polymorpha to disulfoton (10 mg/L), thiometon (6 mg/L), and its activated oxygen analogue demeton-S-methyl (6 mg/L) corroborate earlier findings of organophosphate resistance and accumulation in the organism. Mortality occurred not before the ninth day of exposure. Mortality was induced at high ambient water concentrations and must b...
متن کاملLong-term demography of a zebra mussel (Dreissena polymorpha) population
1. We used long-term data and a simulation model to investigate temporal fluctuations in zebra mussel populations, which govern the ecological and economic impacts of this pest species. 2. The size of the zebra mussel (Dreissena polymorpha) population in the Hudson River estuary fluctuated approximately 11-fold across a 13-year period, following a cycle with a 2–4 year period. 3. This cycling w...
متن کاملStructural-based Differences in Ecotoxicity of Benzoquinoline Isomers to the Zebra Mussel (dreissena Polymorpha)
Effects of four benzoquinoline isomers on the filtration rate of the zebra mussel (Dreissena polymorpha) were analyzed, to study the effect of minor differences in chemical structure on adverse biological effects. Filtration rates were measured after 48 h of exposure to different concentrations of acridine, phenanthridine, benzo[f]quinoline, and benzo[h]quinoline in the water. The 50% effective...
متن کاملModels to Predict Potential Occurrence and Density of the Zebra Mussel, Dreissena polymorpha
Limnological features of different lakes may limit the density of, or even completely restrict, populations of the European zebra mussel, Dreissena polymorpha. We developed statistical models to predict the occurrence (presence or absence) and density (number per square metre) of Dreissena in lakes, based on multivariate correlations between the density of Dreissena populations and the limnolog...
