Climate warming has a role in promoting cyanobacteria blooms expansion caused by eutrophication.To evaluate the response patterns of different algae on combined effects of climate warming and eutrophication, we simulated different increasing temperature amplitudes in late spring (20+3, 23+3, 20+6℃) and five phosphorus concentration levels (0, 0.05, 0.15, 0.30, 0.50 mg/L) to test the response of the three common algae (Microcystis aeruginosa, Anabaena flos-aquae and Scenedesmus obliquus) in eutrophic water. The results showed that the growth rate of three algae showed different response patterns. The growth rate of M. aeruginosa increased significantly with increased phosphorus concentration and temperature, which suggested that additive effect of temperature and phosphorus increased. The growth rate of A. flos-aquae was subject to temperature in the phosphorus concentration of 0.30 mg/L, with no significant additive effect in the other phosphorus concentration levels. The response in growth rate of S. obliquus presented a great variability at different levels, but no significant difference. With increased phosphorus concentration, the additive effect of temperature and phosphorus on the growth of M. aeruginosa showed logistic increasing pattern. The growth of A. flos-aquae and S. obliquus presented the sensitive response to the additive effect at a specific temperature or a specific nutrient concentration, and no significant trend. The photochemical results showed that F_v/F_m of Microcystis declined more significantly than those of A. flos-aquae and S. obliquus, which might be due to that the pigment per cell could not be accumulated under this rapid growth rate of Microcystis. The F_v/F_m of A. flos-aquae showed weak variability with temperature and phosphorus increasing. The F_v/F_m of S. obliquus had a slight decreasing trend with increasing temperature. The dynamics of photochemical characteristics in the three algae were consistent with changes in their growth. In summary, Microcystis had a stronger response to the increased temperature and phosphorus concentration, which led to high growth rates and might contribute to the expansion of cyanobacterial blooms.
