Fig. 5: Temperature-dependent evolution of the agricultural footprint.
A The relationship between beetle mass produced and host bean consumed. Each assay is represented by an individual datapoint. The slopes of the dashed lines correspond to the temperature-specific constant (Cm) giving the amount of host consumed per beetle produced (23 °C: 3.17, 29 °C: 3.66, 35 °C: 3.55). B The two independent metrics used to predict the agricultural footprint (see equations 5 and 6). C The predicted footprint of each line (using equation 5) relative to respective ancestor raised at 29 °C (grey hatched line). Means ± 95% CIs are presented for each experimental evolution line and were calculated based on equation 5 and parametric bootstraps based on standard errors for each underlying trait (see Fig. 4A–D). The effect of life-history adaptation at cold temperature is small, but life-history adaptation at hot temperature almost doubles the agricultural footprint relative to the ancestral impact.
