The effect of changed nutrient load and water turbidity is higher (Figure 3b) than the effect of temperature. The effects are almost mirrored for decrease or increase. While in clear lakes the potential species richness increases under increased turbidity and nutrients, it decreases under decreased turbidity and nutrients. In turbid lakes, the effect is the opposite. In intermediate lakes, the effect depends on the depth. In shallow water, an increase / decrease of nutrients and turbidity results prevailingly in an increase / decrease of species, while in deep water the effect is the opposite.
