We investigated the effects of infochemicals from Daphnia carinata on the morphology, polysaccharides yield and PSII-efficiency in Scenedesmus obliquus. Infochemicals released from D. carinata induced colony formation in S. obliquus. The contents of soluble extracellular polysaccharides, bounded extracellular polysaccharides, and the total polysaccharides per cell in the induced colonies of S. obliquus increased significantly relative to those of the unicells, which indicated that Daphnia -associated infochemicals could also stimulate S. obliquus to increase the synthesis of extracellular polysaccharides. The increased extracellular polysaccharides may play an important role in cementing S. obliquus cells together to form colonies. In addition, no significant differences in growth, the maximal efficiency of PSII photochemistry (Fv/Fm), and the effective quantum yields of PSII (ΦPSII) were detected between unicellular and induced colonial populations, which showed that the cost of induced colony formation was not reflected on these indices.
