Abstract The literature was reviewed mine the direct temperature effects on thetic capacity (P_max), specific respiration and growth rate of bloom-forming (Anabaena, Aphanizomenon, Microcysti toria) and to assess the importance perature effects on cyanobacterial lakes. This analysis is supported by field Microcystis aeruginosa in a hypertrophic literature and field data show that P_max growth rate are temperature-dependent w usually at 25 °C or greater. The four in their response to low temperatures w cystis being most severely limited be 15 °C. Oscillatoria tended to tolerate range of temperatures. However, an of field data from representative lakes a world indicated that direct temperature secondary to indirect temperature effect and nutrients in determining the bloom-forming cyanobacteria in lakes, perature effects probably act synergisti other factors in this process.
