英文摘要	Temperature and nutrient availability, which are major drivers of consumer performance, are dramatically affected by global change. To date, there is no consensus on whether warming increases or decreases consumer needs for dietary carbon (C) relatively to phosphorus (P), thus hindering predictions of secondary production responses to global change. Here, we investigate how the dietary C:P ratio optimising consumer growth (TERC:P: Threshold Elemental Ratio) changes along temperature gradients by combining a temperature-dependent TERC:P model with growth experiments on Daphnia magna. Both lines of evidence show that the TERC:P response to temperature is U-shaped. This shape indicates that consumer nutrient requirements can both increase or decrease with increasing temperature, thus reconciling previous contradictive observations into a common framework. This unified framework improves our capacity to forecast the combined effects of nutrient cycle and climatic alterations on invertebrate production. © 2020 John Wiley & Sons Ltd/CNRS
