Median T air values for panting/gular flutter (pant 50) were significantly related to (a) log10 body mass (log10 M b) (negative relationship), b prop_act (negative relationship), and c drinking dependency (D: drinking species; ND: non-drinking species); pant 50 was lower in species that rely on surface water. The insets represent partial residuals of the model including all three above-mentioned variables. The filled and clear circles represent drinking and non-drinking species, respectively
