Using a global synthesis of size spectra data from pelagic food webs, this study finds that size structure is not driven by temperature as often suggested, but by the nutrient status of the system. This means that modest phytoplankton declines projected for key fishing grounds at mid-latitudes will amplify into substantial reductions in the supportable biomass of fish.
