We find consistently stronger declines among formerly common species in marine and terrestrial assemblages, while freshwater assemblages show no clear directional pattern. Rare species present at the start also decline, but less so than common species, while colonists that were not present at the start of the time series compensate for losses within the rarest abundance category.
