Sceloporus thermal requirements

Thermal requirement data of lizard populations of the genus Sceloporus was obtained from the literature. We collected data on preferred body temperature (Tpref), body temperature in the field (Tb), critical minimum temperature (CTmin), and critical maximum temperature (CTmax) of Sceloporus lizards. Additionally, we reported air and substrate temperature at the location of capture, if reported in the papers, and the relation of body temperature with these environmental temperatures. Whenever possible, we reported coordinates and elevation of the study sites, with available data on environmental temperatures (i.e., bioclim data, data from nearby meteorological stations, and the Köppen-Geiger climate classification). When reported, thermal efficiency indexes are given (i.e. thermoregulation accuracy, thermoquality of the habitat, and thermoregulation efficiency). 

Methods
Thermal requirement data of lizard populations of the genus Sceloporus. Thermal requirement data was obtained from published work, undergraduate or graduate thesis, and unpublished data of the authors. Full references are given within the file.

Geographic coordinates, when not given in the original research paper, were geo-referenced with Google Maps.

Data on body size (maximum snout vent length) were obtained from Roll et al. 2017 and Meiri 2018.

Data on environmental temperatures were obtained with the packages Bioclim (Hijmans and Van Etten 2012, Fick and Hijmans 2017) and GSODR (Sparks et al. 2017) in R. 

The Köppen-Geiger classification at the site of the populations was obtained with the kgc package (Bryant et al. 2017) in R (R Core Team 2021).
