Predictability of the impact of multiple stressors on the keystone species Daphnia.

ABSTRACT: Eutrophication and climate change are two of the most pressing environmental issues affecting up to 50% of aquatic ecosystems worldwide. Mitigation strategies to reduce the impact of environmental change are complicated by inherent difficulties of predicting the long-term impact of multiple stressors on natural populations. Here, we investigated the impact of temperature, food levels and carbamate insecticides, in isolation and in combination, on current and historical populations of the freshwater grazer Daphnia. We used common garden and competition experiments on historical and modern populations of D. magna 'resurrected' from a lake with known history of anthropogenic eutrophication and documented increase in ambient temperature over time. We found that these populations response drama
