Data from "The repeatability of thermal reaction norms for locomotor activity in juvenile newts"

We repeatedly examined the influence of body temperature (13, 18, 23, and 28°C) and individual identity on locomotor activity in juvenile alpine newts, Ichthyosaura alpestris, over three consecutive weeks. Locomotor activity was characterized by four parameters: covered distance, mean velocity, frequency of movements, and total activity rate (all directional and non-directional movements). We found out that locomotor activity is a complex trait, which can be characterized by several parameters with varying individual repeatability and thermal dependency. This information should be considered for both planning further locomotor activity experiments and modeling ectotherm responses to climate change.

本研究在连续三周的实验周期内，反复测定了体温（13、18、23及28℃）与个体身份对幼体高山欧螈（Ichthyosaura alpestris）运动活动的影响。运动活动通过四项参数进行表征：移动总距离、平均移动速度、运动频次以及总活动率（涵盖所有定向与非定向运动）。研究结果表明，运动活动属于复杂性状，可通过多项参数进行表征，且不同参数的个体重复性与温度依赖性存在差异。上述结论可为后续运动活动相关实验的规划设计，以及外温动物对气候变化响应的模型构建提供重要参考。
