Dataset: Thermal repeatability of tonic immobility in newts

We examined thermal repeatability of tonic immobility in juveniles of two sympatric amphibians, smooth (Lissotriton vulgaris, n=40) and alpine (Ichthyosaura alpestris, n=40) newts. Tonic immobility was characterized using two metrics, the proportion of immobility response and immobility duration. Each individual was repeatedly measured at 13, 18, 23, and 28C.<br>本研究针对两种同域分布的两栖类幼体——滑螈（Lissotriton vulgaris，n=40）与阿尔卑斯螈（Ichthyosaura alpestris，n=40）的强直静止（tonic immobility）温度重复性展开探究。本研究采用两项指标对该行为进行表征：静止反应比例与静止持续时长。所有受试个体均在13℃、18℃、23℃及28℃四个温度梯度下接受重复测量。
