Population-level Ae. aegypti fitness (rmax) by resource supply (0.1 (low) or 1 mg larva−1 day−1 (high)) across temperatures. Fitness estimates for each treatment, with 95% confidence intervals (CIs). The three data points for each treatment represent rmax estimated using the 95% CI bounds of the exponents for the scaling of lifetime fecundity with wing length (electronic supplementary material, equation S1, figure S2). The lightest greyscale hue estimates derive from the lower 95% CIs, the mid-range hue estimates with closed symbols derive from the slopes, and the darkest hue derives from the upper 95% CIs.
