Shading denotes the preferred model in each case as determined by minimum AIC score. ΔAIC is the difference in AIC between every model with the preferred model. Fixed effects of temperature, age, order caught and generation were included in both juvenile and adult models with an additional fixed effect of repeat in adult models
