Data for: A size-based perspective on the decoupling between compositional and functional changes in planktonic communities

Recent studies have shown a decoupling in the way community composition and functions respond to environmental changes. A common pattern observed is that aggregated functions at the community level are more stable than community composition, which is likely the result of functional compensatory dynamics driven by interspecific differences in response to environmental change. However, the mechanisms by which these patterns emerge remain largely unexplored. Here, we investigated in a mesocosm experiment for four weeks the compositional and functional responses of edible phytoplankton (<64µm) and cladoceran zooplankton communities to climate warming (a constant increase of +3.5°C plus heat wave) and eutrophication (nutrient additions) from a size-based perspective. Our results show that warming increases small-sized taxa and decreases large-sized taxa within both phytoplankton and zooplankton community composition. We found that such opposite responses of different-sized taxa contribute..., , Please contact Konghao Zhu [e-mail] with any questions.Â
