Visualized experimental design & analysis. Each density dependence curve originates from a dilution assay with 5 starting densities replicated thrice. Each curve therefore comprises of 15 datapoints that contribute to one set of demographic parameters and 15 sets of parameters describing response in movement and morphological traits. Each datapoint is constructed through image analysis of picture series from two sample points in time, Tstart - Tend. The full experimental design of temperature x pollution x species x strains yields a total of 54 density dependence curves, thus totaling to 54 parameter sets describing demography and 810 sets describing response in movement and morphological traits. Linear models on both datasets separately are used to test our first two hypotheses, after which linear models on the combined dataset are used to test our third hypothesis
