Flight thermoregulatory behaviour of <i>Scarabaeus sacer</i>.

<p>(A) Individual variation of T_thorax (in red) and T_abdomen (in blue). Environmental temperature (T_ambient) (in green) was maintained during each experiment. (B) Comparison of slopes of T_thorax, T_abdomen and T_ambient variation during flight (<i>N</i> = 27; Kruskal-Wallis test with the Conover-Inman post hoc test for pairwise comparisons, α<0.05); black dots indicate the median values; temperatures with the same letter did not differ significantly from each other. (C) Thermal image of <i>S. sacer</i> during flight showing the strong contrast between T_thorax and T_abdomen.
