摘　　要：行为热调节是外温动物体温调节的主要方式。传统观点认为行为热调节仅存在于胚后阶段,然而近年来研究表明爬行动物胚胎具备行为热调节能力。本文回顾了爬行动物胚胎行为热调节的发现和研究进展,探讨了胚胎行为热调节的生态适应意义,分析了胚胎如何感知温度以完成行为热调节,指出了该领域的未来研究方向。Ectotherms rely primarily on behavioral thermoregulation to raise their body temperatures.Traditionally,it is assumed that behavioral thermoregulation only exists in post-embryonic stages.However,recent studies have shown that reptile embryos have the capability of behavioral thermoregulation.Here we review the discovery and research progress of behavioral thermoregulation in reptile embryos,discuss the ecological and adaptive significance of behavioral thermoregulation in embryos,analyze how embryos sense temperature to complete behavioral thermoregulation,and point out some future research directions in this field.
