We synthesize population trends for species initially rare or common across assemblages from 4748 sites within 129 studies spanning terrestrial, freshwater, and marine ecosystems. We find consistently stronger declines among formerly common species in marine and terrestrial assemblages, while freshwater assemblages show no clear directional pattern.
