Behavioural aspects of thermoregulation are examined in each of the four species which constitute the Sphenomorphus quoyi species complex (an allopatric group of lizards, with similar Voluntary temperatures, restricted to southeast Australia).Shade air temperatures during emergence of S. quoyi and S. tympanum (warm temperate) in the field are 15.5°C and 17.5°C respectively when fifty percent of the population have emerged. Those for S. tympanum (cool temperate) and S. kosciuskoi are 10.0°C and 10.5° C respectively. Laboratory studies on emergence rendered similar temperatures to those found in the field. It appears that both ambient temperatures and commencement of the light phase may alter onset of emergence and submergence behaviour.Shuttling behaviour (movement between sunlit and shaded surfaces) is considered to be an important aspect of behavioural thermoregulation in these species. Following a consideration of the vegetation form and density associated with each species it is suggested that shuttling behaviour patterns are functional adaptations. This thermoregulatory behaviour could explain the absence of widespread sympatric populations within this species complex.
在构成斯氏石龙子物种复合体（一种分布于澳大利亚东南部的异域蜥蜴类群，具有相似的自主体温）的四个物种中，对体温调节的行为方面进行了研究。当50%的群体出现时，野外斯氏石龙子和鼓膜石龙子（暖温带）出现时的阴凉处气温分别为15.5°C和17.5°C。鼓膜石龙子（凉温带）和科氏石龙子的相应气温分别为10.0°C和10.5°C。实验室关于出现情况的研究得出了与野外相似的温度。似乎环境温度和光照阶段的开始都可能改变出现和潜入行为的开始时间。穿梭行为（在阳光照射和阴凉表面之间移动）被认为是这些物种行为体温调节的一个重要方面。在考虑了与每个物种相关的植被形态和密度之后，有人提出穿梭行为模式是功能性适应。这种体温调节行为可以解释这个物种复合体内没有广泛的同域种群的现象。
