Abstract

Most species of lizards control their thermoregulation through certain behaviors. This can include basking under the sun and moving into shade, changing body position in relation to the sun and moving to shaded regions. In this project I observed two different Sceloporus malachiticus lizard groups to evaluate their thermoregulatory behaviors. I evaluated the aspects of body, substrate and air temperatures, behavior and flight distances for both groups. My results showed that while air and substrate temperatures were significant factors in the lizard’s thermoregulation, substrate temperatures played a stronger role. Furthermore, lizards showed increased activity earlier in the mornings and exhibited resting behaviors through most of the days. There was no significant correlation found between flight distance and body temperature. La mayoría de las especies de lagartijas controlan su termorregulación a través de determinados comportamientos. Estos incluyen asolearse y ponerse a la sombra, cambiar la posición de sus cuerpos con relación al sol y moverse a sitios sombreados. En este estudio, observé dos grupos de Sceloporus malachiticus para evaluar sus comportamientos de termoregulación. Evalué en los dos grupos la temperatura de cuerpo, la temperatura del aire y del substrato, así como sus distancias de escape (conocidas en la literatura como “flight distances”). Mis resultados muestran que tanto las temperaturas del aire y del substrato son factores significativos en la termorregulación de estas lagartijas, pero que el substrato es más importante. Las lagartijas mostraron un aumento de actividad en horas más tempranas y descansaron la mayor parte de las tardes. No hubo una correlación significativa de las distancias de escape y la temperatura corporal.
