Figure 1.

Warmer temperatures are not associated with selection for smaller body size in animals. The figure shows the relationship between standardized selection (a) gradients or (b) differentials (with error bars of s.e. for each estimate) on animal body size and study-centred annual mean temperature. The blue lines show the overall regression (solid blue line) from models 1 and 2 in table 2 along with the 95% prediction interval (dotted blue lines). The panels do not show outliers (estimated selection coefficients greater than 3.0, which were included in the analysis), which affects the scale on the figure; but see electronic supplementary material, figure S2 for the equivalent figure with all the data (note that all analyses used the full dataset).
