Table 1.
Measures of the relationship between active and sleep phase on parameter spaces constructed from principal component analyses in Agamid lizards. Areas of multivariate normal ellipses (at 95% confidence interval) for each phase are unitless; values in parentheses represent percentages of total area of parameter space. Results of PERMANOVA tests on observations along principal components 1 and 2, with the associated model R2 values in parentheses. ‘Variance’ indicates results of multivariate homogeneity of groups dispersions tests. Dashes denote no tests or calculations performed due to lack of variability in data. Statistically significant tests (α = 0.05) in bold
