Phytoplankton growth and stoichiometric responses to warming, nutrient addition and grazing depend on lake productivity and cell size.

Phytoplankton C:P ratios in ambient conditions (ambient nutrients, temperature and without grazers) were higher in the larger size fraction as compared to the smaller size fraction for the highest productivity system ( p < 0.05, Figure 4 a), and marginally significant for the lowest productivity system ( p = 0.05, Figure 4 a).
