Fig. 2 in Comparative thermoregulation of sympatric endothermic and ectothermic cicadas (Homoptera: Cicadidae: Tibicen winnemanna and Tibicen chloromerus )

Fig. 2 Evening Tb distribution of T. chloromerus (solid line, filled circles, y ˆ 9.47 + 0.708x, r ˆ 0.761) and body temperature as a function of Ta in T. winnemanna (dashed line, open circles, y ˆ 16.34 + 0.618x, r ˆ 0.695) producing sound (''active'' animals) during the species' normal evening activity period. The slope of the regression for T. chloromerus is not significantly dierent than one, indicating that the species is a thermoconformer during the evening (t ˆ)9.673, df ˆ 4, P ˆ 0.1941). The slope of the regression for T. winnemanna is significantly dierent than one, indicating that T. winnemanna regulates Tb without access to solar radiation (t ˆ)5.736, df ˆ 92, P 0:00001)
