Table 1
Summary statistics of maximum, minimum, mean and standard deviation of temperature, dissolved oxygen (DO) and phytoplankton biomass. Epilimnion (n) = 255, metalimnion (n) = 153, hypolimnion (n) = 153. Probability values calculated for vertical differences in physicochemical parameters among epilimnion, metalimnion and hypolimnion. Sample size (n): temperature (20), DO (20), phytoplankton biomass (21), light intensity (7), Secchi depth (7).
