Does microcystin disrupt the induced effect of Daphnia kairomone on colony formation in Scenedesmus?
چکیده انگلیسی
In natural aquatic system, Scenedesmus and Microcystis species usually coexist. Microcystins are released into water after lysis of Microcystis cells during the collapse of heavy blooms. The released toxins can then come into contact with a wide range of aquatic organisms. In this study, we used filtered Daphnia test water containing kairomone from Daphnia magna to stimulate the inducible colony formation in Scenedesmus obliquus under microcystin-contaminated system, to examine how microcystin affects the induced effect of Daphnia kairomone on colony formation in S. obliquus. The results showed neither microcystin nor Daphnia kairomone affected the growth of S. obliquus. Microcystin neither promoted nor impaired the overall Daphnia-induced colony formation in S. obliquus, except reducing the proportion of eight-celled colonies on day 2, indicating that the effect of microcystin was just short-term and in general did not disrupt grazer-induced colony formation of S. obliquus.
