Robustness to thermal variability differs along a latitudinal gradient in zooplankton communities

Abstract Determining how thermal variability will affect the structure, stability, and function of ecological communities is becoming increasingly important as global warming is predicted to affect not only average temperatures but also increase the frequency of long runs of high temperatures. Latit...
