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

Description

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.
