This dataset contains data to accompany the publication: Mueller CA and St Onge CJ. Temperature influences inter-individual variability in morphological and physiological traits of Baja California chorus frog tadpoles. Accepted manuscript. Phil. Trans. R. Soc. B. The files include Excel files with all trait data, R code file for all graphing and analyses performed, and a supplementary file with additional figures and tables. Abstract of study: Inter-individual variability is the range of phenotypes within a population and can shape adaptive responses to environmental change. However, how temperature influences this variability remains unclear despite its importance for predicting population resilience to warming. We tested how rearing temperature (15°C and 22°C) affects both trait means and variability in time to stage, size, oxygen consumption rate (V̇O2), and swim speed in Baja California chorus frog (Pseudacris hypochondriaca) tadpoles. Mean time to stage and morphological traits decreased at 22°C, while mean mass-specific V̇O2 and swim speed increased. Variance (s2, absolute variation) was lower at 22°C for time to stage and mass, higher at 22°C for mass-specific V̇O2, and similar for length and swim speed. Coefficient of variation (CV, relative variation) was higher at 22°C for mass, tail length and depth, and mass-specific V̇O2, indicating trait-specific changes in canalization. Log-transformed Q10 response ratios for trait means (lnRRQ10), variance (lnVRQ10) and CV (lnCVRQ10) revealed strong thermal sensitivity for means but more limited and trait-specific responses in variability. Thus, temperature effects on variability are trait-specific and variability does not always change with, or in the same direction as, trait means. These phenotypic changes may have ecological consequences that influence physiological performance during subsequent life stages.
