ANOVAs per single life history trait (mortality, fecundity, size and age at maturity) calculated for the three common garden experiments testing for the effect of population, treatment and their interaction terms. The populations are as in Fig. 1, each comprising 10 Daphnia magna genotypes and representing different time periods. CGE1 - Temperature treatment; CGE2 - Temperature and food levels; CGE3 - temperature and insecticide Carbaryl. Significant P-values are shown in bold.
