Combined effects of oxytetracycline concentration and algal food level on the life-table demography of Brachionus calyciflorus (Rotifera)
The increase in Scenedesmus obliquus density from 2.0 × 106 to 4.0 × 106 cells mL−1 decreased the magnitude of stimulatory effects of lower concentrations of OTC but enhanced that of inhibitory effects of high concentration of OTC on the survival, asexual reproduction and population growth of Brachionus calyciflorus. So did the decrease in algal density from 2.0 × 106 to 1.0 × 106 cells mL−1.
