Depth dependent potential species richness changes under increased water surface temperature of +1.5°C or +3°C (a) and under increased (+25%) or decrease (-25%) turbidity and nutrients (b) for eutraphentic, mesotraphentic and oligotraphentic species within clear, intermediate, and turbid lakes. The change is determined in comparison to the depth dependent species richness of each species group within each lake in the base scenario and given in change of number of species. The points show the mean changes of the lakes per depth and species group, while the vertical bars show the respective standard deviation. Besides the single effects of temperature increase (a) and coupled turbidity and nutrient change (b), we show the pure interactive effects of a temperature increase of +3°C and an increased or decreased turbidity and nutrient level, by subtracting the single effects from the combined effects (c).
