Supplementary Fig. 2 Bias estimation in measured versus standardized Tcrit. (a) Reported critical temperature estimates Tcrit versus standardized values for a 24 h exposure after accounting for mass effects. (b) Difference between Tcrit before and affecter the standardization procedure, to obtain an estimate of bias, plotted against standardized Tcrit, which controls for confounding effects of variable exposure times and body size differences. Similar reported and standardized Tcrit fall on the dotted line in both panels.
