Filenko, E. Isakova, D. Gershkovich] The effects of ethanol, potassium chloride, and potassium dichromate on the lifespan and fecundity of cladoceran Ceriodaphnia affinis have been studied experimentally. The average lifespan and female fecundity increase at ethanol concentrations of 0.002 mg/L and 0.02 mg/L and at a potassium chloride concentration of 0.1 mg/L. Only a concentration of 0.0001 mg Cr/L increased the lifespan of the cladocerans by 108% in comparison with the control condition within a wide spectrum of tested concentrations of this agent. The reason for such a phenomenon is discussed, as is its ecological role.
