Figure 2. Ecological niche and distribution analyses.A. Niche overlap between northern and southern clades forSceloporus zosteromus . B. Niche breadth for all genetic clades. C. Present day distribution area for all clades.D. Change in distribution area from LGM to present for all clades. E. Example of distribution model for S. zosteromus for present day and LGM CCSM climatic conditions, shows a contraction of the distribution for the northern and southern clades. The gray outline indicates the sea-level boundary for LGM conditions.
