Abstract: The temperature-size rule (TSR) refers to the observation that a wide variety of organisms reach smaller sizes under warmer temperatures. Although various hypotheses have been stated about the mechanisms underlying TSR, a general understanding is still lacking. In this context, it seems that Dynamic Energy Budget (DEB) theory could be useful, as it constitutes a mechanistic framework that predicts growth and development from individual energetics. However, a critical assumption of this framework is that temperature affects all physiological rates equally, which prevents it from capturing the TSR. It remains an open question if and how the DEB framework can be used to capture the TSR patterns.
