The majority of species in ecosystems are rare, but the ecosystem consequences of losing rare species are poorly known. We examine the impacts that rare species have on functional diversity using trait-based metrics and four different definitions of rarity. We find that rare species contribute to functional diversity when rarity is defined by maximum abundance, geographic range, and habitat specificity; however, rare species are functionally redundant when defined by mean abundance.
