What is Effect of Temperature on Photosynthesis-light Response and Growth of Four Phytoplankton Species Isolated from a Tidal Freshwater River about?
Three cyanobacteria (__Microcystis aeruginosa__ Kütz. emend. Elenkin, __Merismopedia tenuissima__ Lemmermann, and __Oscillatoria__ sp.) and one diatom (__Aulacoseira granulata__ var. __angustissima__ O. Mull. emend. Simonsen) were isolated from the tidal freshwater Potomac River and maintained at 23° C and 40 μmol photons·m^−2^·s^−1^ on a 16:8 L:D cycle in unialgal culture. Photosynthetic parameters were determined in nutrient‐replete cultures growing exponentially at 15, 20, 25, and 30° C by incubation with ^14^C at six light levels. __P__ ^B^~max~ was strongly correlated with temperature over the entire range for the cyanobacteria and from 15 to 25° C for __Aulacoseira__, with __Q__~10~ ranging from 1.79 to 2.67. The α values demonstrated a less consistent temperature pattern. Photosynthetic parameters indicated an advantage for cyanobacteria at warmer temperatures and in light‐limited water columns. __P__ ^B^~max~ and __I__~k~ values were generally lower than comparable literature and field values, whereas α was generally higher, consistent with a somewhat shade acclimated status of our cultures. Specific growth rate (μ), as measured by chlorophyll change, was strongly influen
