Evolutionaire ecotoxicologie in opgewarmde vijvers: effecten op aquatische subsidies

In eco-evolutionary multi-stressor research on global change, three key aspects needed to increase realism are largely ignored: (i) the effects of the predicted increases in the magnitude of daily temperature fluctuations (DTFs) and heat waves under future warming; (ii) the role of thermal evolution in shaping the impact of (multiple) stressors; and (iii) the subsidies and carry-over effects from one ecosystem to another. I will address these three knowledge gaps by focusing on the combination of warming and pollution as a set of model stressors. I will quantify the impact of thermal evolution on aquatic subsidies under pesticide exposure in heated ponds. For this, I will focus both on the quantity (numbers emerging) and quality (stoichiometry and PUFA content) of the aquatic subsidies. Furthermore, I will quantify the carry-over effects of the aquatic subsidies by testing for effects on the performance of a terrestrial predator and hereby study how thermal evolution shapes these carry-over effects.
