  abstract = {{T}he human alteration of habitats is a major driver in the decline of biodiversity worldwide. {H}owever, the relationships between different forms of rarity, including both taxonomic and functional aspects, are poorly known. {T}wo relationships were examined in this study: (i) between the different forms of taxonomic rarity and functional originality of lotic fishes; and (ii) between rarity indices and the degree of human alterations. {S}tream fish communities at 429 stream and river sites were sampled between 2013 and 2018. {T}he taxonomic rarity of fishes was characterized based on their local rarity, habitat specificity and geographical restrictedness. {T}he functional originality of each species was also quantified by using ecomorphological traits, and the relationships between the different indices and their responses to human habitat degradation were explored. {O}nly weak or medium level correlations were found among the indices of taxonomic rarity. {A} combined taxonomic rarity index showed that overall taxonomic rarity was determined most strongly by local rarity, followed by habitat specificity, and finally, geographical restrictedness. {F}unctional originality was not related either to individual rarity indices or the combined taxonomic rarity index. {M}ean taxonomic rarity of species was correlated with the degree of habitat degradation of the sites. {C}ontrary to taxonomic rarity, mean functional originality of species increased with the degree of human alteration. {T}his study shows that a more exact characterization of species rarity requires multiple metrics, including functional ones, because these indices respond differently to human alterations. {C}ombined indices of rarity can help to prioritize species level conservation actions, although single rarity metrics are still needed to adapt these actions to species attributes (e.g. endemism or unique functions). {S}pecies level conservation would benefit from including the evaluation of functional rarity into conservation policy.},
