Evolutionarily conserved thermal biology across continents: The North American lizard Plestiodon gilberti (Scincidae) compared to Asian Plestiodon
- 1. The lizard genus Plestiodon (Scincidae; formerly Eumeces) is widespread in North America and Asia, but the thermal biology of only a few species has been studied.
2. We measured several thermal physiological traits in Plestiodon gilberti, among the few measurements of temperature sensitivity in a North American scincid lizard.
3. Critical thermal minimum (7.7 °C) and maximum (42.3 °C), preferred body temperature (31.5 °C), and optimal temperature for sprinting (34.1 °C) were very similar to published values for several Asian species of Plestiodon.
4. These results suggest that thermal physiology in Plestiodon lizards may be evolutionarily conserved over large temporal and spatial scales.
