Summary results for the anova analyses of residuals calculated from a single RMA line. A significant anova P-value indicates a significant difference between nocturnal and diurnal activity patterns. All variables produced a significant anova except for when measurements of the sclerotic ring are considered alone, indicating that activity pattern can not be interpreted from an isolated sclerotic ring with no other information.
