研究表明，行为体温调节是蜥蜴的特征(Cowles和Bogert 1944)，在正常活动期间，属于同一属的广泛分离的物种保持几乎相同的平均体温(Bogert 1949a，1949b)。对当地种群的研究表明，无论季节、地点或海拔高度，个体物种体温的“正常活动范围”曲线几乎是相同的。每一个物种都有一个“临界体温”，实际上是一个“偏好区”，其平均值对于青少年和成年人来说几乎是相同的，无论性别。此外，由于蜥蜴利用其周围温度水平在时间和空间上的变化，远亲物种的代表有可能并排出现，但仍然保持显著不同的平均体温(Bogert 1949a)。来自基质的热量有一定的重要性，但晒太阳在它们的热经济中起着更重要的作用。
It has been shown that behavioral thermoregulation is characteristic of lizards (Cowles and Bogert 1944) and that virtually identical mean body temperatures are maintained during periods of normal activity by widely separated species belonging to the same genus (Bogert 1949a, 1949b). Studies of local populations show that curves for the "normal activity range" in the body temperatures of individual species are nearly identical, regardless of the season, the locality, or its elevation. Each species has an "eccritic body temperature," actually a zone of "preference," the mean of which is virtually identical for juveniles as well as for adults of either sex. Furthermore, since lizards avail themselves of variations to be found in time and space in the thermal level of their surroundings, it is possible for representatives of distantly related genera to occur side by side and still to maintain significantly different mean body temperatures (Bogert 1949a). Heat derived from the substratum is of some importance, but basking plays a more significant role in their heat econ-
