Reptile populations were sampled in spring and summer in various habitats: grassland, creosote shrubland, pinyon-juniper woodland, cottonwood forest, subalpine forest, and subalpine meadow. On 18 sites mark-release methods were used; on 12 sites, all animals were kept for museum specimens. Museum specimen preparations included skulls, whole skeletons, and alcohol preservations; all specimens had tissue samples (liver, heart) taken for ultra-cold preservations for genetic analyses; some were karyotyped. All museum specimens were checked for internal parasites.
