The preferred body temperature (Ts) that a lizard voluntarily selects in a laboratory thermal gradient 4Postdoc Researcher, Centro de Investigaciones provides a reasonable estimate of what a lizard would attain in the wild with a minimum of associate costs Biológicas del Noroeste, Playa Palo de Santa Rita in absence of constraints for thermoregulation. In this study we evaluated accuracy of modifi ed iButtons Sur, 23096 La Paz, Baja California Sur, México to estimate Tb and Ts of three lizard species (Sceloporus poinsettii and Sceloporus jarrovii in northeastern Durango, and Ctenosaura oaxacana in southern Oaxaca, Mexico). We used linear regression models to Received: 31 March, 2018 obtain equations for predicting T and T of these species from iButtons. Results from regression models Accepted: 21 December, 2018 b s showed that T is a good indicator of T for S.
