| 中文摘要 | Studies over the last two decades suggested that mixotrophy could be an important adaptive strategy for some bloom-forming dinoflagellates. In the coastal waters adjacent to the Changjiang River estuary in the East China Sea, recurrent blooms of dinoflagellates Prorocentrum donghaiense, Karenia mikimotoi and Alexandrium catenella started to appear from the beginning of the 21 century, but roles of mixotrophy in the formation of dinoflagellate blooms were not well understood. In the current study, mixotrophy-based growth of four selected bloom-causative dinoflagellate species, i.e. K. mikimotoi, A. catenella, P. donghaiense and Prorocentrum micans, were studied. Dinoflagellates were co-cultured with different prey organisms, including bacterium Marinobacter sp., microalgae Isochrysis galbana and Hemiselmis virescens, under a variant of nutrient conditions. It was found that growth of dinoflagellate K. mikimotoi was significantly promoted with the presence of prey organisms. Growth of P. donghaiense and P. micans was only slightly improved. For A. catenella, the addition of prey organisms has no effects on the growth, while both of the two prey microalgae I. galbana and H. virescens were killed, probably by allelochemicals released from A. catenella. There was no apparent relationship between nutrient conditions and the mixotrophy-based growth of the tested dinoflagellates. Based on the results of the growth experiment, it is implicated that mixotrophy may play different roles in the growth and bloom of the four dinoflagellate species. It can be an important competitive strategy for K. mikimotoi. For the two Prorocentrum species and A. catenella, however, the role of mixotrophy is much limited. They may depend more on other competitive strategies, such as phototrophy-based growth and allelopathic effect, to prevail in the phytoplankton community and form blooms. (C) 2013 Elsevier B.V.
