C1-Appendix

134 lizard species with data on 50 niche dimensions including habitat, anatomy, diet, life history, metabolism, and defense. Four other variables (semi arboreal, semi fossorial, crepuscular, and mixed foraging mode) were scored with double entries. Multivariate analyses capture 61.7 % of the total variance in the first 3 dimensions. Lizard niches appear to be tightly constrained.
