Özet:
Intraspecific variability of behavioral thermoregulation in lizards due to habitat, temperature availability, and seasonality is well documented, but variability due to sex is not. Sex-specific thermoregulatory behaviors are important to understand because they can affect relative fitness in ways that result in different responses to environmental changes. The common chuckwalla (Sauromalus ater) is a great model for investigating sex differences in thermoregulation because males behave differently from females while they actively defend distinct territories while females may not. I recorded body temperatures of wild adult chuckwallas continuously from May to July 2016, as well as operative environmental temperatures in crevices and aboveground sites used by chuckwallas for basking. I compared the effect of sex on indices of thermoregulatory accuracy and effectiveness, aboveground activity, and the time chuckwallas selected body temperatures relative to their preferred temperature range (34--39 °C) for May-July. Males and females achieved the same thermoregulatory accuracy and effectiveness, and amount of time at preferred body temperatures, but males were more active aboveground than females, especially in June. These results indicate that different behavioral strategies can accomplish the same thermoregulatory outcomes. Further, chuckwallas might be able to cope with predicted changes in climate that result in a shorter amount of time they could be active at preferred body temperature because these lizards were only active aboveground for one to four hours per day, a fraction of the time available.
