Substrate types used by lizards: (A) percent of natural and human-made substrates on which lizards were found at each site, (B) percent of sub-categories on which lizards were found (left y-axis) and Levins’ B (right y-axis) for each site. Sub-categories include both natural and human-made substrates (e.g., woody encompasses natural trees and logs and human-made wooden posts). Levin’s B is a measure of niche breadth and was calculated using the proportion of lizards found in each substrate sub-category
