Growth and competition between the dinoflagellates Prorocentrum donghaiense and Alexandrium catenella and the diatom Skeletonema costatum sensu lato in response to different forms of phosphorus were investigated in mixed cultures. The results indicated that S. costatum s.l. outcompeted P. donghaiense to become dominant owing to high growth rates,(More)
Colony enlargement in Phaeocystis globosa has been considered as an induced defense strategy that reduces its susceptibility to grazers, but allocation costs inflicted by this plastic morphological defense are poorly understood. We conducted experiments in which P. globosa cultures were exposed to chemical cues from copepods, ciliates and heterotrophic(More)
