Abstract Understanding the interaction between evolutionary history, the current abiotic environment, and biotic interactions is critical for a more nuanced understanding of the response of communities to anthropogenic stressors. We leveraged a long term experiment manipulating temperature in mesocosms containing communities of phytoplankton and zooplankton to examine how evolution in response to long-term community warming affects consumer-resource dynamics at different temperatures.

Are changes of interaction strength with temperature context-dependent? Our definition of consumer–resource interspecific thermal mismatches is based on the comparison of energetic balances and intraspecific thermal mismatches of resources and consumers. Interspecific thermal mismatches combined with the calculation of the consumer–resource energetic balances (CREBs) can help to understand and predict how interaction strength changes with temperature.
