利用实验室的逃逸行为数据和野外的逃逸行为观察，比较了幼年和成年沙蜥的逃逸行为。我们特别研究了差异逃逸反应是否是身体大小的限制，或者青少年的行为是否不同，以最大限度地提高他们的逃逸可能性，同时考虑到他们与大小相关的速度限制。在实验室里，幼年蜥蜴比成年蜥蜴慢，即使剔除了身体大小的影响，它们也会在更短的时间和更短的距离内逃脱。在野外，幼鸟允许更近的接近，在短暂飞行后，通常不会立即躲藏，但如果攻击持续，在连续的短距离奔跑后，幼鸟会这样做。栖息地对幼虫的接近距离影响不大，但覆盖小生境的初始飞行距离和总飞行距离较短。环境温度对幼虫的进近距离和初始飞行距离没有显著影响。然而，总飞行距离与气温显著相关。
We compared the escape behaviour of juvenile and adult Psammodromus algirus lizards, by using data of escape performance in the laboratory and field observations of escape behaviour. We specifically examined whether a differential escape response is a constraint of body size, or whether juveniles behave differently in order to maximize their escape possibilities taking into account their size-related speed limitations. In the laboratory, juvenile lizards were slower than adult lizards, and escaped during less time and to shorter distances, even when removing the effect of body size. In the field, juveniles allowed closer approaches and after a short flight usually did not hide immediately, but did so after successive short runs if the attack persists. Approach distance of juveniles was not affected by habitat, but initial and total flight distances were shorter in covered microhabitats. There was no significant effect of environmental temperature on approach and initial flight distances of juveniles. However, the total flight distances were significantly correlated with air temperatures.
