Supporting Data and Code for: "<i>Metamorphosis reverses the behavioural phenotype in Rana arvalis along a latitudinal gradient</i>"

This dataset accompanies a study investigating the regional variation of proactive behavioural traits (boldness, activity, and exploration) and their association with developmental growth across a latitudinal gradient in <i>Rana arvalis</i>. Behavioural assays were conducted at tadpole and froglet developmental stages across five geographic regions spanning two genetically distinct postglacial clusters in northern Europe.<br><br>The dataset includes individual-level behavioural measurements, developmental growth metrics, and associated metadata, along with the R scripts used for data processing and statistical analysis.
