不同绿藻浓度下铜绿微囊藻对轮虫生活史的影响
Effect of Microcystis aeruginosa on the Rotifer Life History at Different Concentrations of Green Algae
摘要
Abstract
The effect of Microcystis aeruginosa on the life history of Brachionus calyciflorus and B. rubens at different concentrations of Scenedesmus obliquus was investigated by using the life table experiments. The results showed that M. aeruginosa suppressed the survivorship and reproduction of B. calyciflorus at the high concentration of S. obliquus (105 and 106 cells/mL) . The intrinsic increase rate ( rm ) and net reproductive rate ( R0 ) of B. calyciflorus in control group were significantly higher than those in the group with M. aeruginosa (p<0. 01). However, M. aeruginosa could stimulate the rotifer population at the low concentration of S. obliquus (104 cells/mL). M. aeruginosa suppressed the survivorship, reproduction and demographic parameters of B. rubens at any concentration of S. obliquus and this inhibition was relieved with the increase of concentration of S. obliquus. These results indicate that the effects of M. aeruginosa on the rotifer population may be influenced by the other food availability and this influence may be different with the different rotifer species.关键词
