Fig. C1. Density distribution plots of the effects of seasonally constant warming on average heat fluxes in the time period between the algal onset and Daphnia maximum. Net heat flux H, short wave radiation HS, long wave radiation from the atmosphere HA, long wave radiation from the water surface HW, heat flux due to evaporation HE and conduction HC averaged between algal onset and Daphnia maximum in the reference scenario and scenarios with seasonally constant warming of 1 , 2, 3, and 4°C. Significant changes with warming occurred for H (slope: -3.6  ±  1.1, p < 0.01), HS(slope: -5.3 ±  0.9, p < 0.001), HA (slope: 3.1 ±  0.5, p < 0.001) and HW (slope: -2.0 ±  0.3, p < 0.001), whereas HE and HC did not change significantly. Note the signs on the y-axis in the different panels: Positive heat fluxes are directed from the atmosphere to the lake, negative heat fluxes are directed from the lake to the atmosphere. Lines connect the means (black dots) of each distribution. Rugs indicate individual data points.
