Fig. 1 in Comparative thermoregulation of sympatric endothermic and ectothermic cicadas (Homoptera: Cicadidae: Tibicen winnemanna and Tibicen chloromerus )

Fig. 1 Diurnal body temperature (Tb) of Tibicen chloromerus (solid line, filled circles, y ˆ 31.35 + 0.202x, r ˆ 0.217) and T. winnemanna (dashed line, open circles, y ˆ 18.70 + 0.498x, r ˆ 0.619) as a function of ambient temperature (Ta). The slope of the linear regression is significantly dierent from one, suggesting thermoregulation (t ˆ)5.739, df ˆ 21, P <0.00001) for T. chloromerus and (t ˆ)2.509, df ˆ 10, P <0.02) for T. winnemanna
