Fig. 2. Skin colour values (A) and grey scale values (B) for frogs exposed to 20 and 30°C in both the dark and the light (Series I experiments) for at least 1 h each. Values are means ± s.e.m. In A, light grey bars refer to the average red value, dark grey values to the average green value, and black bars to the average blue values. Both light level and temperature had significant effects. *Significant difference from 20°C dark exposed frogs; {dagger}significant difference from 30°C dark exposed frogs.
