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 (V˙O2) and swim speed in Baja California chorus frog (Pseudacris hypochondriaca) tadpo
