摘要：We examined the effects of infochemicals released by Daphnia magna and Daphnia pulex on the morphology and growth of Scenedesmus obliquus and Microcystis aeruginosa under laboratory conditions. Exposure to the Daphnia culture media filtrate promoted colony formation in S. obliquus significantly, while no colony formation was observed in M. aeruginosa. In addition, no significant difference in the growth was detected between the controls and the treatments in either S. obliquus or M. aeruginosa. These observations suggest that S. obliquus and M. aeruginosa may have adopted different ecological strategies to resist potential grazing by Daphnia.
